[0050] The light-emitting display device according to the embodiment of the present disclosure may be any one of an organic light-emitting diode display device, a quantum dot light-emitting diode display device, and an inorganic light-emitting diode display device. That is, the light-emitting display device according to the embodiment of the present disclosure may be an electroluminescent display device. In addition, the light-emitting display device according to the embodiment of the present disclosure may be a micro light-emitting diode display device.

[0051] The light-emitting display device according to the embodiment of the present disclosure can be used as various electronic devices. The electronic device can be, for example, a television, a monitor, etc., and can be an automotive electronic device installed and used in a vehicle. In particular, the light-emitting display device according to the embodiment of the present disclosure can be installed on the dashboard of the vehicle to provide the driver and passengers with information and various images related to the operation of the vehicle. In the following, for the convenience of description, the light-emitting display device installed on the dashboard of the vehicle to be used will be described as an example of the light-emitting display device according to the embodiment of the present disclosure.

[0052] like Figure 1 and Figure 2As shown, a light-emitting display device according to an embodiment of the present disclosure may include: a light-emitting display panel 100, which includes a display area DA for displaying an image and a non-display area NDA arranged outside the display area DA; a gate driver 200, which provides a gate signal GS to a plurality of gate lines GL1 to GLg arranged in the display area DA of the display panel 100; a data driver 300, which provides a data voltage Vdata to a plurality of data lines DL arranged in the display area DA of the display panel 100; a control driver 400, which controls the driving of the gate driver 200 and the data driver 300; and a power supply unit 500, which provides power to the control driver 400, the gate driver 200, the data driver 300 and the light-emitting display panel 100.

[0053] First, the light-emitting display panel 100 may include a display area DA and a non-display area NDA. Gate lines GL1 to GLg, data lines DL, and sub-pixels P may be disposed in the display area DA. Therefore, an image may be displayed in the display area DA. Here, g is a natural number. The non-display area NDA may surround the periphery of the display area DA.

[0054] like Figure 2 As shown, the sub-pixel P included in the light-emitting display panel 100 may include a pixel driving circuit PDC and a first light-emitting device ED1 and a second light-emitting device ED2 connected to the pixel driving circuit PDC, and the pixel driving circuit PDC includes a switching transistor Tsw1, a storage capacitor Cst, a driving transistor Tdr, a first reference transistor Tsw2a, a second reference transistor Tsw2b, a first viewing angle control transistor Tvc1 and a second viewing angle control transistor Tvc2.

[0055] A first terminal of the driving transistor Tdr may be connected to a first voltage supply line PLA through which a first voltage ELVDD is supplied, and a second terminal of the driving transistor Tdr may be connected to the first and second light emitting devices ED1 and ED2 .

[0056] A first terminal of the switching transistor Tsw1 may be connected to the data line DL, a second terminal of the switching transistor Tsw1 may be connected to a first terminal of the storage capacitor Cst, and a gate of the switching transistor Tsw1 may be connected to the gate line GL.

[0057] The data voltage Vdata may be provided through the data line DL from the data driver 300. The gate signal GS may be provided through the gate line GL from the gate driver 200. The gate signal GS may include a gate pulse GP for turning on the switching transistor Tsw1 and a gate-off signal for turning off the switching transistor Tsw1.

[0058] The first reference transistor Tsw2a and the second reference transistor Tsw2b may be provided to measure a threshold voltage or mobility of the driving transistor Tdr, or to provide a reference voltage VREF to the pixel driving circuit PDC.

[0059] A first terminal of the first reference transistor Tsw2a may be connected to a reference line RL, through which a reference voltage VREF is provided, a second terminal of the first reference transistor Tsw2a may be connected to a second terminal of the first viewing angle control transistor Tvc1 and the first light emitting device ED1, and a gate of the first reference transistor Tsw2a may be connected to a reference control line RCL, through which a reference control signal RCS is provided.

[0060] A first terminal of the second reference transistor Tsw2b may be connected to a reference line RL, through which a reference voltage VREF is provided, a second terminal of the second reference transistor Tsw2b may be connected to a second terminal of the second viewing angle control transistor Tvc2 and the second light-emitting device ED2, and a gate of the second reference transistor Tsw2b may be connected to a reference control line RCL, through which a reference control signal RCS is provided.

[0061] The reference line RL may be connected to the data driver 300, and may be connected to the power supply unit 500 through the data driver 300. For example, the reference voltage VREF provided from the power supply unit 500 may be provided to the sub-pixel SP through the reference line RL, the sensing signal transmitted from the sub-pixel SP may be converted into a digital sensing signal in the data driver 300, and the digital sensing signal may be transmitted to the control driver 400.

[0062] A first terminal of the storage capacitor Cst may be connected to the second terminal of the switching transistor Tsw1 , and a second terminal of the storage capacitor Cst may be connected to the gate of the driving transistor Tdr.

[0063] A first terminal of the first viewing angle control transistor Tvc1 may be connected to the second terminal of the driving transistor Tdr, a second terminal of the first viewing angle control transistor Tvc1 may be connected to the first light emitting device ED1, and a gate of the first viewing angle control transistor Tvc1 may be connected to the first control signal line CL1.

[0064] A first terminal of the second viewing angle control transistor Tvc2 may be connected to the second terminal of the driving transistor Tdr, a second terminal of the second viewing angle control transistor Tvc2 may be connected to the second light emitting device ED2, and a gate of the second viewing angle control transistor Tvc2 may be connected to the second control signal line CL2.

[0065] That is, the gate of the first viewing angle control transistor Tvc1 may be connected to the first control signal line CL1, and the gate of the second viewing angle control transistor Tvc2 may be connected to the second control signal line CL2. The first control signal line CL1 and the second control signal line CL2 may be arranged in each of the m light-emitting areas. Here, m is a natural number greater than 1.

[0066] For example, when the display area DA is Figure 1 When the light emitting area EA1 to EA12 is divided into 12 light emitting areas, m is 12. In this case, the gate of the first viewing angle control transistor Tvc1 disposed in the first light emitting area EA1 can be connected to the first control signal line CL1, and the gate of the second viewing angle control transistor Tvc2 disposed in the first light emitting area EA1 can be connected to the second control signal line CL2.

[0067] In addition, a gate of the first viewing angle control transistor Tvc1 disposed in the twelfth light emitting area EA12 may be connected to the first control signal line CL1, and a gate of the second viewing angle control transistor Tvc2 disposed in the twelfth light emitting area EA12 may be connected to the second control signal line CL2.

[0068] The first and second control signal lines CL1 and CL2 disposed in the first emission area EA1 are different from the first and second control signal lines CL1 and CL2 disposed in the twelfth emission area EA12. That is, the first and second control signal lines CL1 and CL2 may be disposed in each of the emission areas.

[0069] In this case, the polarity type of the first viewing angle control transistor Tvc1 may be the same as the polarity type of the second viewing angle control transistor Tvc2.

[0070] For example, when the first viewing angle control transistor Tvc1 is an N-type transistor, the second viewing angle control transistor Tvc2 may be an N-type transistor, and when the first viewing angle control transistor Tvc1 is a P-type transistor, the second viewing angle control transistor Tvc2 may be a P-type transistor.

[0071] In this case, when the first viewing angle control transistor Tvc1 is turned on, the second viewing angle control transistor Tvc2 may be turned off, and when the first viewing angle control transistor Tvc1 is turned off, the second viewing angle control transistor Tvc2 may be turned on.

[0072] For example, Figure 2As shown, the gate of the first viewing angle control transistor Tvc1 is connected to the first control signal line CL1, and the gate of the second viewing angle control transistor Tvc2 is connected to the second control signal line CL2. Therefore, when signals of different levels are input through the first control signal line CL1 and the second control signal line CL2, one of the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 may be turned on, while the other may be turned off.

[0073] More specifically, in Figure 2 In the embodiment, when a first control signal with a low level is input to the first control signal line CL1 and a second control signal with a high level is input to the second control signal line CL2, a first viewing angle control transistor Tvc1 formed by a P-type transistor can be turned on, and a second viewing angle control transistor Tvc2 formed by a P-type transistor can be turned off.

[0074] In addition, Figure 2 In the embodiment, when a first control signal with a high level is input to the first control signal line CL1 and a second control signal with a low level is input to the second control signal line CL2, the first viewing angle control transistor Tvc1 formed by the P-type transistor can be turned off, and the second viewing angle control transistor Tvc2 formed by the P-type transistor can be turned on.

[0075] like Figure 2 As shown, the pixel driving circuit PDC may further include a connecting transistor Tsw3 and light emitting transistors Tsw4a and Tsw4b.

[0076] A first terminal of the connection transistor Tsw3 may be connected to the gate of the driving transistor Tdr and the second terminal of the storage capacitor Cst, a second terminal of the connection transistor Tsw3 may be connected to the second terminal of the driving transistor Tdr, and a gate of the connection transistor Tsw3 may be connected to the reference control line RCL.

[0077] A first terminal of the first light emitting transistor Tsw4a may be connected to the second terminal of the switching transistor Tsw1 and the first terminal of the storage capacitor Cst, a second terminal of the first light emitting transistor Tsw4a may be connected to the reference line RL, and a gate of the first light emitting transistor Tsw4a may be connected to the light emitting line EL.

[0078] A first terminal of the second light emitting transistor Tsw4b may be connected to a second terminal of the driving transistor Tdr and a second terminal of the connection transistor Tsw3, a second terminal of the second light emitting transistor Tsw4b may be connected to a first terminal of the first viewing angle control transistor Tvc1 and a first terminal of the second viewing angle control transistor Tvc2, and a gate of the second light emitting transistor Tsw4b may be connected to the light emitting line EL. A light emitting signal EM may be provided to the light emitting line EL.

[0079] The first light emitting device ED1 connected to the pixel driving circuit PDC may include a first electrode receiving a first voltage ELVDD through a driving transistor Tdr, a second light emitting transistor Tsw4b and a first viewing angle control transistor Tvc1, a second electrode connected to a second voltage supply line PLB supplied with a second voltage ELVSS, and a light emitting layer disposed between the first electrode and the second electrode.

[0080] The second light emitting device ED2 connected to the pixel driving circuit PDC may include a first electrode receiving a first voltage ELVDD through a driving transistor Tdr, a second light emitting transistor Tsw4b and a second viewing angle control transistor Tvc2, a second electrode connected to a second voltage supply line PLB supplied with a second voltage ELVSS, and a light emitting layer disposed between the first electrode and the second electrode.

[0081] The structure of the sub-pixel P applied to the light-emitting display device according to the embodiment of the present disclosure is not limited to Figure 2 Therefore, the structure of the sub-pixel P can be changed into various shapes.

[0082] In particular, if Figure 2 As shown, the pixel driving circuit PDC applied to the light-emitting display device according to the embodiment of the present disclosure may include a light-emitting control unit ECU (e.g., a light-emitting control circuit) and a viewing angle control unit VCU (e.g., a viewing angle control circuit). The light-emitting control unit ECU may control the level of the current supplied to the light-emitting device ED1 or ED2 and the timing of supplying the current to the light-emitting device ED1 or ED2. The viewing angle control unit VCU may control the viewing angle of the light output from the light-emitting device ED1 or ED2. In this case, the structure and function of the light-emitting control unit ECU may be changed into various shapes.

[0083] The control driver 400 may realign the input image data Ri, Gi, and Bi transmitted from the external system 600 by using the timing synchronization signal TSS transmitted from the external system, and may generate a data control signal DCS to be provided to the data driver 300 and a gate control signal GCS to be provided to the gate driver 200 .

[0084] For this reason, Figure 3As shown, the control driver 400 may include: a data aligner 430 (e.g., a circuit) which realigns the input image data Ri, Gi, and Bi to generate the image data Data and transmits the image data Data to the data driver 300; a control signal generator 420 (e.g., a circuit) which generates a gate control signal GCS and a data control signal DCS by using a timing synchronization signal TSS; an input unit 410 (e.g., a circuit) which transmits the timing synchronization signal TSS transmitted from the external system 600 to the control signal generator 420 and transmits the input image data Ri, Gi, and Bi transmitted from the external system 600 to the data aligner 430; and an output unit 440 (e.g., a circuit) which provides the image data Data generated by the data aligner 430 and the data control signal DCS generated by the control signal generator 420 to the data driver 300 and provides the gate control signal GCS generated by the control signal generator 420 to the gate driver 200.

[0085] The control signal generator 420 may generate a power control signal provided to the power supply unit 500 .

[0086] The control driver 400 may further include a storage unit (eg, memory) for storing various information. The storage unit 450 may be as follows: Figure 3 It is shown to be included in the control driver 400, but may be separated from the control driver 400 and provided independently.

[0087] The control signal generator 420 may generate viewing angle control signals VCS and provide them to the viewing angle control lines.

[0088] The viewing angle control signal VCS may be provided to the viewing angle switching unit 700 disposed in the non-display area NDA.

[0089] The external system 600 may perform a function of driving and controlling the driver 400 and the electronic device.

[0090] For example, when the electronic device is installed on the vehicle, the external system 600 may receive various sound information, image information, and letter information through the communication network, and may receive various image information related to the operation of the vehicle through other electronic devices installed on the vehicle. The external system 600 may transmit the received image information to the control driver 400. The external system 600 may convert the image information into input image data Ri, Gi, and Bi, and transmit the input image data Ri, Gi, and Bi to the control driver 400.

[0091] The power supply unit 500 may generate various powers and supply the generated powers to the control driver 400 , the gate driver 200 , the data driver 300 , and the light-emitting display panel 100 .

[0092] The gate driver 200 may be directly embedded in the non-display area NDA by using a gate in panel (GIP) type, or the gate driver 200 may be disposed in the display area DA in which the light emitting device ED is disposed, or the gate driver 200 may be disposed on a chip on film mounted in the non-display area NDA.

[0093] The gate driver 200 may provide gate pulses GP1 to GPg to the gate lines GL1 to GLg.

[0094] The switching transistor Tsw1 may be turned on when the gate pulse GP generated by the gate driver 200 is supplied to the gate of the switching transistor Tsw1 included in the subpixel P. The data voltage Vdata supplied through the data line DL may be supplied to the subpixel P when the switching transistor Tsw1 is turned on.

[0095] When the gate-off signal generated by the gate driver 200 is provided to the switching transistor Tsw1, the switching transistor Tsw1 may be turned off. When the switching transistor Tsw1 is turned off, the data voltage may no longer be provided to the sub-pixel P.

[0096] The gate signal GS supplied to the gate line GL may include a gate pulse GP and a gate-off signal.

[0097] In order to supply the gate pulses GP1 to GPg to the gate lines GL1 to GLg, as shown in FIG. Figure 4 As shown in FIG. 1 , the gate driver 200 may include stages ST1 to STg connected to the gate lines GL1 to GLg.

[0098] Each of the stages ST1 to STg may be connected to one gate line GL, but may be connected to at least two gate lines GL.

[0099] To generate the gate pulses GP1 to GPg, the gate start signal VST and at least one gate clock GCLK generated by the control signal generator 420 may be transmitted to the gate driver 200. For example, the gate start signal VST and the at least one gate clock GCLK may be included in the gate control signal GCS.

[0100] One of the stages ST1 to STg may be driven by the gate start signal VST to output a gate pulse GP to the gate line GL. The gate pulse GP may be generated by the gate clock GCLK.

[0101] At least one of the signals output from the stage ST outputting the strobe pulse may be provided to another stage ST to drive the other stage ST. Therefore, the strobe pulse may be output in the other stage ST.

[0102] For example, the stages ST may be driven sequentially to sequentially supply the gate pulses GP to the gate lines GL.

[0103] As described above, each of the stages ST1 to STg may be connected to one gate line GL, but may also be connected to at least two gate lines GL.

[0104] In addition, when the sub-pixel P has Figure 2 In the structure shown, each of the stages ST1 to STg can be connected to at least one gate line GL and at least one reference control line RCL. The reference control signal RCS output through the reference control line RCL can be generated by a method that is the same as or similar to the method of generating the gate pulse, and then can be sequentially output to the reference control line RCL.

[0105] In this case, connect to Figure 2 The gate line GL is shown as a stage and connected to Figure 2 The levels of the reference control lines RCL shown may be the same or different.

[0106] Furthermore, a stage for generating a gate signal to be supplied to the gate line GL and a stage for generating a reference control signal RCS to be supplied to the reference control line RCL may be independently provided in the gate driver 200 .

[0107] That is, the number, type, and connection structure of lines connected to one stage may vary according to the structure of the sub-pixel P and the driving method of the sub-pixel P.

[0108] In addition, if Figure 2 As shown, when the emission line EL to which the emission signal EM is supplied is connected to the subpixel P, after the emission signal EM is generated in the gate driver 200 by the same method as the gate signal GS, the emission signal EM may be output to the emission line EL.

[0109] For example, the gate driver 200 may generate a gate signal GS and a light emitting signal EM, and may also generate a reference control signal RCS.

[0110] In this case, the strobe signal GS, the light emitting signal EM and the reference control signal RCS can be Figure 4 The stages St1 to STg shown are generated. Alternatively, a stage for generating the gate signal GS, a stage for generating the emission signal EM, and a stage for generating the reference control signal RCS may be independently set in the gate driver 200. Alternatively, a stage for generating the gate signal GS and the reference control signal RCS, and a stage for generating the emission signal EM may be independently set in the gate driver 200.

[0111] Therefore, the detailed structure of the gate driver 200 may be changed into various shapes according to the structure of the sub-pixel P, the driving method of the sub-pixel P, and the number and type of lines connected between the sub-pixel P and the gate driver 200 .

[0112] The data driver 300 may provide a data voltage Vdata to the data line DL.

[0113] For this reason, Figure 5 As shown in , the data driver 300 may include: a shift register 310, which outputs a sampling signal; a latch 320, which latches the image data Data received from the control driver 400; a digital-to-analog converter 330, which converts the image data Data transmitted from the latch 320 into a data voltage Vdata and outputs the data voltage Vdata; and an output buffer 340, which outputs the data voltage transmitted from the digital-to-analog converter 330 to the data line DL based on a source output enable signal SOE.

[0114] The shift register 310 may output a sampling signal by using a data control signal DCS received from the control signal generator 420. For example, the data control signal DCS transmitted to the shift register 310 may include a source start pulse SSP and a source shift clock signal SSC.

[0115] The latch 320 may latch the image data Data sequentially received from the control driver 400 and then simultaneously output the image data Data to the digital-to-analog converter 330 based on the sampling signal.

[0116] The digital-to-analog converter 330 may convert the image data Data transmitted from the latch 320 into a data voltage Vdata and output the data voltage Vdata.

[0117] The output buffer 340 may simultaneously output the data voltages Vdata transmitted from the digital-to-analog converter 330 to the data lines DL of the light-emitting display panel 100 based on the source output enable signal SOE transmitted from the control signal generator 420 .

[0118] To this end, the output buffer 340 may include a buffer 341 storing the data voltage Vdata transmitted from the digital-to-analog converter 330 and a switch 342 outputting the data voltage Vdata stored in the buffer 341 to the data line DL based on a source output enable signal SOE.

[0119] For example, when the switch 342 is turned on based on the source output enable signal SOE simultaneously supplied to the switch 342 , the data voltage Vdata stored in the buffer 341 may be supplied to the data line DL through the switch 342 .

[0120] The data voltage Vdata supplied to the data line DL may be supplied to the sub-pixel P connected to the gate line GL supplied with the gate pulse GP.

[0121] Finally, the viewing angle switching unit 700 may be disposed in the non-display area NDA, and the viewing angle switching unit 700 may be connected to the emission area EA in a one-to-one relationship.

[0122] For example, Figure 1 As shown, when the display area DA is divided into 12 emission areas EA1 to EA12, 12 viewing angle switching units 700 may be provided in the non-display area NDA, and one viewing angle switching unit 700 may be connected to a sub-pixel P provided in one emission area EA.

[0123] Based on the first control signal and the second control signal transmitted from the viewing angle switching unit 700, the first light-emitting unit may be driven without driving the second light-emitting unit in the light-emitting area EA, or the second light-emitting unit may be driven without driving the first light-emitting unit. Therefore, in the light-emitting area EA, light having a first viewing angle may be output or light having a second viewing angle may be output.

[0124] Hereinafter, additional features of the above-described configuration will be described.

[0125] The display area DA may include pixel row lines and pixel column lines provided with sub-pixels P. For example, a pixel row line may refer to a line along which Figure 1 The sub-pixels P are arranged in the first direction (X-axis direction) shown in FIG. 1 , and the pixel column line may refer to a sub-pixel P arranged along the first direction (X-axis direction) shown in FIG. 1 . Figure 1 The sub-pixels P are arranged in the second direction (Y-axis direction) shown in .

[0126] The sub-pixel P may be any one of a red sub-pixel emitting red light, a green sub-pixel emitting green light, a blue sub-pixel emitting blue light, and a white sub-pixel emitting white light. A unit pixel may include at least two sub-pixels. For example, white light may be output by a unit pixel.

[0127] The subpixel P may include first and second light emitting devices ED1 and ED2, a pixel driving circuit PDC including transistors driving the first and second light emitting devices ED1 and ED2, a first lens disposed on the first light emitting device ED1, and a second lens disposed on the second light emitting device ED2.

[0128] The first light emitting unit may include a first light emitting device ED1 driven by a first viewing angle control transistor Tvc1 and a first lens disposed on the first light emitting device ED1. In addition, the second light emitting unit may include a second light emitting device ED2 driven by a second viewing angle control transistor Tvc2 and a second lens disposed on the second light emitting device ED2.

[0129] The first light emitting unit may be driven by a first viewing angle control transistor Tvc1 , and the second light emitting unit may be driven by a second viewing angle control transistor Tvc2 .

[0130] The first viewing angle control transistor Tvc1 may be connected between the first light emitting unit and a driving transistor Tdr that controls the level of current supplied to the first light emitting unit or the second light emitting unit. The second viewing angle control transistor Tvc2 may be connected between the driving transistor Tdr and the second light emitting unit. The second light emitting transistor Tsw4b may be connected between the first viewing angle control transistor Tvc1 and the driving transistor Tdr and between the second viewing angle control transistor Tvc2 and the driving transistor Tdr.

[0131] The first lens provided in the first light emitting unit and the second lens provided in the second light emitting unit may have different shapes.

[0132] In particular, the exit angle (ie, viewing angle) of light output through the first lens may be different from the viewing angle of light output through the second lens.

[0133] For example, the sub-pixel P may be operated in a wide viewing angle mode, a sharing mode, or a first mode (hereinafter referred to as a sharing mode (SM)) by driving the first light-emitting device ED1 to output light through the first lens, so that the light has a first viewing angle during the wide viewing angle mode. In addition, the sub-pixel P may be operated in a narrow viewing angle mode, a privacy mode, or a second mode (hereinafter referred to as a privacy mode (PM)) that limits the viewing angle by driving the second light-emitting device ED2 to output light through the second lens, so that the light has a second viewing angle during the narrow viewing angle mode, and the second viewing angle is smaller than the first viewing angle.

[0134] The narrow viewing angle mode may refer to a mode having a viewing angle (hereinafter referred to as a narrow viewing angle or a second viewing angle) narrower than a viewing angle in a wide viewing angle mode (hereinafter referred to as a wide viewing angle or a first viewing angle).

[0135] That is, the light emitting display device according to the embodiment of the present disclosure may selectively drive the first light emitting device ED1 and the second light emitting device ED2 of the sub-pixel P, thereby controlling the viewing angle of the sub-pixel P. A detailed description thereof will be provided later.

[0136] The display area DA may be divided into at least two light emitting areas along a first direction, and the display area DA may be divided into at least two light emitting areas along a second direction different from the first direction. Figure 1 As shown, the display area DA can be divided into four light-emitting areas along the first direction X, and can be divided into three light-emitting areas along the second direction Y. That is, Figure 1 A light emitting display panel including a display area DA divided into 12 light emitting areas EA1 to EA12 is shown.

[0137] For example, when Figure 1 When the first light-emitting device ED1 is driven in the sub-pixel P of the first light-emitting area EA1 shown and light is output through the first lens, the first light-emitting area EA1 can operate in a wide viewing angle mode, and when the second light-emitting device ED2 is driven in the sub-pixel P of the first light-emitting area EA1 and light is output through the second lens, the first light-emitting area EA1 can operate in a narrow viewing angle mode.

[0138] In this case, when the first light-emitting device ED1 is driven in the sub-pixel P of the second light-emitting area EA2 and light is output through the first lens, the second light-emitting area EA2 can operate in a wide viewing angle mode, and when the second light-emitting device ED2 is driven in the sub-pixel P of the second light-emitting area EA2 and light is output through the second lens, the second light-emitting area EA2 can operate in a narrow viewing angle mode.

[0139] Each of the third to twelfth light emitting areas EA3 to EA12 may also be operated in the wide viewing angle mode or the narrow viewing angle mode.

[0140] For example, all of the first to twelfth light-emitting areas EA1 to EA12 may be operated in a wide viewing angle mode or a narrow viewing angle mode. Alternatively, a first subset of the first to twelfth light-emitting areas EA1 to EA12 may be operated in a wide viewing angle mode, and a second subset of the first to twelfth light-emitting areas EA1 to EA12 may be operated in a narrow viewing angle mode.

[0141] Therefore, the position of the light emitting area operated in the wide viewing angle mode and the position of the light emitting area operated in the narrow viewing angle mode can be changed differently. In particular, the position of the light emitting area operated in the wide viewing angle mode and the position of the light emitting area operated in the narrow viewing angle mode can be changed differently along the first direction X, and can be changed differently along the second direction Y.

[0142] The light emitting display device according to an embodiment of the present disclosure may further include a touch screen provided in the display area DA for sensing a user's touch.

[0143] The touch screen may be coupled with the light-emitting display panel 100 or may be embedded in the light-emitting display panel 100 .

[0144] For example, the light-emitting display panel 100 may include: a pixel driving circuit layer including a transistor disposed on a substrate; a light-emitting device layer including a light-emitting device disposed on the pixel driving circuit layer; an encapsulation layer, which is configured to encapsulate the light-emitting device layer; a touch sensor array including a touch electrode disposed on the encapsulation layer; and a lens array disposed on the touch sensor array. In this case, the light-emitting display panel 100 may further include an optical film, an optical adhesive (OCA), a cover substrate, and a protective film sequentially disposed on the lens array. The light-emitting display panel 100 may further include a color filter array, the color filter array including a color filter and a black matrix disposed between the touch sensor array and the lens array.

[0145] As described above, the gate driver 200 may generate the gate signal GS and the emission signal EM, and may also generate the reference control signal RCS. In the following description, the gate signal GS, the emission signal EM, and the reference control signal RCS are referred to as scan signals.

[0146] That is, the gate driver 200 may provide at least one scan signal to each pixel row line by using the gate control signal GCS provided from the control driver 400. For example, Figure 2 A sub-pixel P to which three scanning signals GS, EM and RCS are supplied is shown.

[0147] The transistors provided in the sub-pixel P and the transistors included in the gate driver 200 provided in the display area DA or the non-display area NDA may be formed by at least one of an LTPS transistor using low temperature polysilicon (LTPS) and an oxide transistor using a metal oxide semiconductor. In particular, in order to reduce power consumption, the LTPS transistor and the oxide transistor may coexist in the light-emitting display panel 100.

[0148] The data driver 300 may include Figure 1 A data driver IC (integrated circuit) is shown, and at least one data driver IC may be mounted on the light-emitting display panel 100 . Figure 1 The light emitting display panel 100 on which four data drivers 300 consisting of four data driver ICs are mounted is shown.

[0149] Each data driver IC may be mounted on each circuit film individually. The circuit film on which the data driver IC is mounted may be bonded to the non-display area NDA where the pad area of ​​the display panel 100 is disposed through an anisotropic conductive film (ACF). The circuit film may be a chip on film (COF). In addition, in addition to COF, an FPC (flexible printed circuit) or an FFC (flexible flat cable) may be used as the circuit film.

[0150] The control driver 400 may control the gate driver 200 and the data driver 300 by using the timing synchronization signal TSS provided from the external system 600 and the timing setting information stored therein.

[0151] To this end, the control driver 400 may generate and provide a gate control signal GCS controlling driving timing of the gate driver 200 to the gate driver 200 , and generate and provide a data control signal DCS controlling driving timing of the data driver 300 to the data driver 300 .

[0152] In addition, the control driver 400 may perform various image processing including image quality correction, degradation correction, and brightness correction to reduce power consumption on the received input image data Ri, Gi, and Bi, and may then provide the image processed data Data to the data driver 300 .

[0153] Figure 6 is an exemplary diagram showing an internal structure of a vehicle to which a light emitting display device according to an embodiment of the present disclosure is applied, and 7A to 7F is an exemplary diagram showing how the viewing angle of the light emitting area in the light emitting display panel according to an embodiment of the present disclosure changes. 7A to 7F FIG. 1 shows a light-emitting display panel 100 divided into 12 light-emitting areas EA1 to EA12. Figures 1 to 7F A light emitting display device according to an embodiment of the present disclosure is described.

[0154] For example, Figure 6 As shown, the light-emitting display device 10 according to the embodiment of the present disclosure can be placed in the center of the vehicle dashboard to display images to passengers and drivers in the passenger seats. For example, the light-emitting display panel 100 of the light-emitting display device 10 may include first to twelfth light-emitting areas EA1 to EA12, and the viewing angles of the first to twelfth light-emitting areas EA1 to EA12 can be changed independently.

[0155] Here, the viewing angle refers to a wide viewing angle and a narrow viewing angle. A wide viewing angle means a viewing angle wider than a narrow viewing angle. In the following description, a light-emitting area that outputs an image with a wide viewing angle is referred to as a wide viewing angle mode area or a shared mode area, and a light-emitting area that outputs an image with a narrow viewing angle is referred to as a narrow viewing angle mode area or a privacy mode area.

[0156] First, refer to Fig. 7A , the first to sixth light emitting areas EA1 to EA6 (eg, the first light emitting area) of the light emitting display panel 100 may provide a first image IM1 having a wide viewing angle in the left-right direction to the driver and passengers of the passenger seats. Fig. 7AAs shown, each of the first to sixth light-emitting areas EA1 to EA6 emits light at a wide viewing angle corresponding to a portion of the first image IM1. The first to sixth light-emitting areas EA1 to EA6 jointly display the first image IM1 by causing each light-emitting area to display a corresponding portion of the first image IM1. Therefore, both the passenger and the driver can view the first image IM1.

[0157] The first image IM1 may represent an image providing information related to the operation of the vehicle (hereinafter referred to as a vehicle operation information image, and the vehicle operation information image may also be indicated by the reference numeral IM1). Fig. 7A As shown, the first image IM1 may provide the speed of the vehicle, the mileage of the vehicle, and the fuel amount of the vehicle.

[0158] The vehicle operation information image needs to be seen not only by the driver but also by the passengers of the vehicle. Since the first image IM1 has a wide viewing angle, both the driver and the passengers can see the first image IM1. Therefore, the first to sixth light-emitting areas EA1 to EA6 can be shared mode areas.

[0159] In particular, the vehicle operation information image should be displayed when the vehicle is in operation, to meet established standard display dimensions, and to be displayed in an area that is most visible to the driver. Therefore, when the vehicle (e.g., an object including the display device) is operated (e.g., moved), the display device is in an operating mode (e.g., a first mode) and the vehicle operation information image should be displayed unconditionally, regardless of the driver's selection, and the luminous area that outputs the vehicle operation information image should also be fixed. For example, when the first image IM1 is a vehicle operation information image, the first image IM1 can be fixedly displayed in the first luminous area EA1 to the sixth luminous area EA6, as shown in FIG. Fig. 7A shown.

[0160] In this case, the seventh to twelfth light emitting areas EA7 to EA12 of the light emitting display panel 100 may display the second image IM2 having a narrow viewing angle in the left-right direction to the passenger in the passenger seat rather than the driver in the driving seat so as not to interfere with the driver's driving. Fig. 7A As shown, each of the seventh to twelfth light-emitting areas EA7 to EA12 emits light at a narrow viewing angle corresponding to a portion of the second image IM2. The seventh to twelfth light-emitting areas EA7 to EA12 jointly display the second image IM2 by causing each light-emitting area to display a corresponding portion of the second image IM2.

[0161] During the operation mode, the second image IM2 is different from the first image IM1. The second image IM2 may represent, for example, an image received through various communication networks (hereinafter referred to as a general image, and the general image may also be represented by the reference numeral IM2). For example, the second image IM2 may be a TV video, an Internet video, or a playback file video.

[0162] Because the general image is irrelevant to the operation of the vehicle, is provided by the passenger's selection, and attracts the driver's attention, the general image may distract the driver. Therefore, it is not necessary for the driver to see the second image IM2. Because the second image IM2 has a narrow viewing angle that is visible to the passenger but not to the driver, the driver cannot see the second image IM2, while the passenger can see the second image IM2. Therefore, the seventh light-emitting area EA7 to the twelfth light-emitting area EA12 can be a privacy mode area.

[0163] Reference Figure 7B , when the vehicle is parked or not operated, the display device is in a non-operating mode (e.g., the second mode), and the first to twelfth light-emitting areas EA1 to EA12 can provide the driver and the passenger with a second image IM2 having a wide viewing angle in the left and right directions based on the user's selection. That is, the first to sixth light-emitting areas EA1 to EA6 display a first portion of the second image IM2 at a wide viewing angle, and the seventh to twelfth light-emitting areas EA7 to EA12 display a second portion of the second image IM2 at a wide viewing angle to jointly display the second image IM2 during the non-operating mode. Figure 7B As shown, each (and therefore both) of the driver and passenger may view the second image IM2 when the vehicle is parked or not being operated and thus stationary.

[0164] Reference Figure 7C , the seventh to twelfth light-emitting areas EA7 to EA12 may be divided based on the user's selection. In this case, the seventh to ninth light-emitting areas EA7 to EA9 may provide the third image IM3 having a wide viewing angle in the left and right directions to the passengers of the driver and passenger seats, while the tenth to EA10 twelfth light-emitting areas EA12 may provide the second image IM2.

[0165] The third image IM3 may represent an image providing auxiliary information related to the operation of the vehicle (hereinafter referred to as a vehicle operation information auxiliary image, and the vehicle operation information auxiliary image may also be represented by the reference numeral IM3). Figure 7C As shown, the third image IM3 may provide location information (eg, navigation information).

[0166] The vehicle operation information auxiliary image IM3 needs to be seen by both the driver and the passenger. Since the third image IM3 has a wide viewing angle, both the driver and the passenger can see the third image IM3. Therefore, the seventh to ninth light-emitting areas EA7 to EA9 may be shared mode areas, and the tenth to twelfth light-emitting areas EA10 to EA12 may be private mode areas.

[0167] Reference Fig.7D , the third image IM3 may be displayed through the seventh light-emitting area EA7 and the tenth light-emitting area EA10, and the second image IM2 may be displayed through the eighth light-emitting area EA8, the ninth light-emitting area EA9, the eleventh light-emitting area EA11, and the twelfth light-emitting area EA12.

[0168] That is, in the light-emitting display device according to the embodiment of the present disclosure, the sharing mode area and the privacy mode area can be changed along the first direction X of the light-emitting display panel, such as FIG. 7A to FIG. 7C As shown, and can be changed along the second direction Y of the light-emitting display panel, as Fig.7D shown.

[0169] Finally, driven Fig. 7A At least one of the seventh to twelfth light-emitting areas EA7 to EA12 of the privacy mode area in the embodiment may be changed to a sharing mode area to display the fourth image IM4. Fig. 7E As shown, the eighth light emitting area EA8 may be changed into a shared mode area to display the fourth image IM4.

[0170] The fourth image IM4 may represent an image providing emergency information related to the operation of the vehicle (hereinafter referred to as an emergency information image, and the emergency information image may also be indicated by the reference numeral IM4). Fig. 7E As shown, the fourth image IM4 may be an image indicating that a dangerous object exists in front of the vehicle. The emergency information image IM4 may be collected by various sensors installed on the vehicle. In addition, the emergency information image IM4 may be a disaster message provided by the government or local government to citizens in the whole country or a specific area through various communication networks, or may be an image provided by a navigation system installed in the vehicle.

[0171] However, if Fig. 7A and Figure 7F As shown, the fourth image IM4 may be displayed by at least one (eg, the third light emitting area EA3 ) of the first to sixth light emitting areas EA1 to EA6 driven in the shared mode area.

[0172] The following will refer to Figures 14 to 25 Describes how to change shared mode areas and private mode areas.

[0173] The light-emitting display device 10 according to an embodiment of the present disclosure is not limited to the light-emitting display device for vehicles as described above, and thus can be applied to various light-emitting display devices, such as a light-emitting display device for mobile devices, a light-emitting display device for IT devices, and a light-emitting display device for TV.

[0174] Figure 8 is an exemplary plan view schematically showing a structure of a sub-pixel of a light-emitting display panel according to an embodiment of the present disclosure, and Fig.9A and Fig. 9B is an exemplary perspective view illustrating the structure of a first lens and a second lens applied to a sub-pixel of a light-emitting display panel according to an embodiment of the present disclosure.

[0175] like Figure 8 As shown, a subpixel P applied to a light-emitting display panel according to an embodiment of the present disclosure may include a first light-emitting device ED1, a second light-emitting device ED2, a first lens LZ1 disposed on the first light-emitting device ED1, and a second lens LZ2 disposed on the second light-emitting device ED2.

[0176] The first lens LZ1 may be disposed on a light traveling path of the first light emitting device ED1. The second lens LZ2 may be disposed on a light traveling path of the second light emitting device ED2. Here, the light traveling path may be, for example, a third direction Z perpendicular to the first direction X and the second direction Y. For example, the first lens LZ1 and the first light emitting device ED1 may be disposed along the third direction Z, and the second lens LZ2 and the second light emitting device ED2 may be disposed along the third direction Z.

[0177] The subpixel P may include at least two second light emitting devices ED2, and the second lens LZ2 may be disposed on a light traveling path of each of the at least two second light emitting devices ED2. The at least two second light emitting devices ED2 may share one first electrode (eg, anode) in the subpixel P.

[0178] In the sub-pixel P, a region where the first lens LZ1 is disposed may be referred to as a first lens region, and a region where the second lens LZ2 is disposed may be referred to as a second lens region.

[0179] like Fig.9A As shown, the first lens LZ1 may be a semi-cylindrical lens elongated in the first direction X. Fig. 9B As shown, the second lens LZ2 may be a hemispherical lens. However, the shapes of the first lens LZ1 and the second lens LZ2 may be variously changed.

[0180] In the following description, the first direction X may be expressed as a left-right direction, a width direction, a horizontal direction, or an X-axis direction. The second direction Y may be expressed as an up-down direction, a length direction, a vertical direction, or a Y-axis direction. The third direction Z may be expressed as a front-back direction, a thickness direction of the light-emitting display panel 100, or a Z-axis direction.

[0181] The first lens LZ1 and the second lens LZ2 may differently control (limit) the viewing angle in the left-right direction X, and may equally control (limit) the viewing angle in the up-down direction Y.

[0182] For example, the first lens LZ1 may control a first viewing angle corresponding to a wide viewing angle because the first lens LZ1 does not limit a traveling path of light emitted from the first light emitting device ED1 within a specific angle in the left-right direction X. The second lens LZ2 may control a second viewing angle to be a narrow viewing angle by limiting a traveling path of light emitted from the second light emitting device ED2 within a specific angle in the left-right direction X.

[0183] Both the first lens LZ1 and the second lens LZ2 can control the viewing angle to be narrow by limiting the light travel path within a specific angle in the up-down direction Y. Figure 6 In the case where the light-emitting display device 10 is applied to a vehicle, the driver's field of vision is prevented from being disturbed by the image displayed on the light-emitting display panel 100 reflected by the front glass of the vehicle.

[0184] When the first light emitting device ED1 is driven in the sub-pixel P, the sub-pixel P may operate in a wide viewing angle mode that does not limit the viewing angle in the left-right direction X.

[0185] When the second light emitting device ED2 is driven in the subpixel P, the subpixel P may operate in a narrow viewing angle mode that limits the viewing angle in the left-right direction X. The wide viewing angle mode may be described as a first mode, and the narrow viewing angle mode may be described as a second mode.

[0186] By switching driving of the first light emitting device ED1 and the second light emitting device ED2 of the sub-pixel P, the sub-pixel P may be switched between a wide viewing angle mode and a narrow viewing angle mode.

[0187] To provide additional description, as described above, the first light emitting unit may include a first light emitting device ED1 driven by a first viewing angle control transistor Tvc1 and a first lens LZ1 disposed on the first light emitting device, and the second light emitting unit may include a second light emitting device ED2 driven by a second viewing angle control transistor Tvc2 and a second lens LZ2 disposed on the second light emitting device.

[0188] In this case, the first light emitting unit or the second light emitting unit may be driven in each of the light emitting areas EA1 to EA12. For example, in each light emitting area, the first light emitting device ED1 disposed in the first light emitting unit may be driven without driving the second light emitting device ED2, or the second light emitting device ED2 disposed in the second light emitting unit may be driven without driving the first light emitting device ED1. Therefore, in each light emitting area EA, light having a wide viewing angle may be output through the first lens LZ1, or light having a narrow viewing angle may be output through the second lens LZ2.

[0189] Therefore, each light emitting area may be a wide viewing angle mode area or a narrow viewing angle mode area.

[0190] Furthermore, since the viewing angles of the light emitting areas can be independently controlled, the light emitting areas can be either wide viewing angle mode areas or narrow viewing angle mode areas regardless of the positions of the light emitting areas.

[0191] Fig.10 is an exemplary plan view showing a structure of three sub-pixels applied to a light-emitting display panel according to an embodiment of the present disclosure, Fig.11 According to the embodiment of the present disclosure Fig.10 An exemplary cross-sectional view taken along line II' shown, and Fig.12 According to the embodiment of the present disclosure Fig.10 The exemplary cross-sectional view taken along the line II-II' shown in FIG. Fig.10 3 sub-pixels BP, RP and GP constituting a unit pixel UP are shown, Fig.11 shows a cross section of a first light emitting unit LU1, and Fig.12 A cross section of a second light emitting unit LU2 is shown.

[0192] For example, a unit pixel UP capable of outputting white light may include a blue sub-pixel BP emitting blue light, a red sub-pixel RP emitting red light, and a green sub-pixel GP emitting green light. Fig.10 shown.

[0193] The blue sub-pixel BP may include a first light emitting unit LU1 and a second light emitting unit LU2. The first light emitting unit LU1 may include a first light emitting device ED1 driven by a first viewing angle control transistor Tvc1 and a first lens LZ1 overlapping the first light emitting device ED1. The second light emitting unit LU2 may include a second light emitting device ED2 driven by a second viewing angle control transistor Tvc2 and a second lens LZ2 overlapping the second light emitting device.

[0194] The red sub-pixel RP may include a first light emitting unit LU1 and a second light emitting unit LU2. The first light emitting unit LU1 may include a first light emitting device ED1 driven by a first viewing angle control transistor Tvc1 and a first lens LZ1 overlapping the first light emitting device ED1. The second light emitting unit LU2 may include a second light emitting device ED2 driven by a second viewing angle control transistor Tvc2 and a second lens LZ2 overlapping the second light emitting device.

[0195] The green sub-pixel GP may include a first light emitting unit LU1 and a second light emitting unit LU2. The first light emitting unit LU1 may include a first light emitting device ED1 driven by a first viewing angle control transistor Tvc1 and a first lens LZ1 overlapping the first light emitting device ED1. The second light emitting unit LU2 may include a second light emitting device ED2 driven by a second viewing angle control transistor Tvc2 and a second lens LZ2 overlapping the second light emitting device.

[0196] In each of the blue sub-pixel BP, the red sub-pixel RP, and the green sub-pixel GP, as shown in FIG. Fig.9A and Fig. 9B As described, the first lens LZ1 and the second lens LZ2 may control the viewing angles in the left-right direction X differently, and may control the viewing angles in the up-down direction Y equally.

[0197] Each first light emitting unit LU1 of the unit pixel UP may include a first light emitting device ED1 and a first lens LZ1. Each second light emitting unit LU2 of the unit pixel UP may include at least one second light emitting device ED2 and at least one second lens LZ2. In this case, at least two second light emitting devices ED2 may share a first electrode (e.g., an anode) 321, a light emitting layer 322, and a second electrode (e.g., a cathode) 323, as shown in FIG. Fig.12 shown.

[0198] The first light emitting device ED1 included in the first light emitting unit LU1 may have the same shape as a lower surface of the first lens LZ1. The size of the first lens LZ1 may be set larger than that of the first light emitting device ED1 to improve emission efficiency of light generated from the first light emitting device ED1.

[0199] The second light emitting device ED2 included in the second light emitting unit LU2 may have the same shape as the lower surface of the second lens LZ2. The size of the second lens LZ2 may be set larger than that of the second light emitting device ED2 to improve emission efficiency of light generated from the second light emitting device ED2.

[0200] Areas of the second light emitting devices ED2 included in the second light emitting units LU2 may be the same.

[0201] However, for each of the sub-pixels BP, RP, and GP, the number of the second light emitting devices ED2 included in the second light emitting unit LU2 may vary. Fig.10 As shown, the number of second light-emitting devices ED2 provided in the second light-emitting unit LU2 of the blue sub-pixel BP may be greater than the number of second light-emitting devices ED2 provided in the second light-emitting unit LU2 of the red sub-pixel RP. The number of second light-emitting devices ED2 provided in the second light-emitting unit LU2 of the red sub-pixel RP may be less than the number of second light-emitting devices ED2 provided in the second light-emitting unit LU2 of the green sub-pixel GP. Therefore, the efficiency deviation of the blue sub-pixel BP, the red sub-pixel RP, and the green sub-pixel GP in the unit pixel UP may be compensated by the number of second light-emitting devices ED2 provided in the second light-emitting unit LU2.

[0202] For each sub-pixel P, the size of the first light emitting device ED1 may be different. Fig.10 As shown, the size of the first light emitting device ED1 of the blue sub-pixel BP may be larger than the size of the first light emitting device ED1 of the red sub-pixel RP. In addition, the size of the first light emitting device ED1 of the red sub-pixel RP may be smaller than the size of the first light emitting device ED1 of the green sub-pixel GP. Therefore, the efficiency deviation of the blue sub-pixel BP, the red sub-pixel RP, and the green sub-pixel GP in the unit pixel UP may be compensated by the size of the first light emitting device ED1 set in the first light emitting unit LU1.

[0203] like Fig.11 and Fig.12 As shown, the light-emitting display panel 100 according to an embodiment of the present disclosure may include: a pixel driving circuit layer, which includes a substrate 101 and transistors Tvc1 and Tvc2 arranged on the substrate 101; a light-emitting device layer, which includes light-emitting devices ED1 and ED2 arranged on the pixel driving circuit layer; an encapsulation layer 800, which is arranged on the light-emitting device layer; and a lens layer, which includes lenses LZ1 and LZ2 arranged on the encapsulation layer 800.

[0204] The light-emitting display panel 100 according to the embodiment of the present disclosure may further include a touch sensor layer disposed between the encapsulation layer 800 and the lens layer. The light-emitting display panel 100 according to the embodiment of the present disclosure may further include a color filter layer including a color filter and a black matrix disposed between the touch sensor layer and the lens layer.

[0205] In the following, reference is made to Figures 10 to 12 Describe the cross-sectional structure of a subpixel. Fig.11 and Fig.12 Shows Fig.10However, each of the red sub-pixel RP and the green sub-pixel GP may also have a cross-section of a blue sub-pixel BP. Fig.11 and Fig.12 The cross-sectional structure is shown.

[0206] That is, each of the sub-pixels BP, RP, and GP of the light-emitting display panel according to an embodiment of the present disclosure may include Fig.11 The first light emitting unit LU1 and Fig.12 The second light emitting unit LU2 is shown.

[0207] like Fig.11 As shown, the first light emitting unit LU1 of the subpixel P may include a first viewing angle control transistor Tvc1, a first light emitting device ED1 connected to the first viewing angle control transistor Tvc1, and a first lens LZ1 disposed on the first light emitting device ED1 to overlap with the first light emitting device ED1.

[0209] In the light-emitting display panel 100 according to an embodiment of the present disclosure, the pixel driving circuit layer disposed on the substrate 101 may include an insulating layer stacked on the substrate 101. For example, the insulating layer may include a buffer layer 110, a gate insulating layer 120, an interlayer insulating layer 130, a passivation layer 140, and a planarization layer 150.

[0210] The substrate 101 may include an insulating material such as glass or plastic. The plastic substrate may be formed of a flexible material. For example, the substrate 101 may include at least one of acrylic resin, epoxy resin, siloxane resin, polyimide resin, and polyamide resin. That is, the substrate 101 may include an organic insulating material.

[0211] The buffer layer 110 may include an inorganic insulating material such as silicon oxide (SiOx), silicon nitride (SiNx), and aluminum oxide (Al2O3), and may have a single layer or a multilayer structure. The buffer layer 110 may prevent impurities such as hydrogen from flowing into the semiconductor layers 211 and 221 through the substrate 101.

[0212] Various transistors constituting the sub-pixel P may be disposed on the buffer layer 110. For example, a first viewing angle control transistor Tvc1 and a second viewing angle control transistor Tvc2 may be disposed.

[0213] Each transistor provided in the sub-pixel P may include a gate, a source, and a drain. In this case, the source and the drain are not fixed and may change according to the voltage and current direction applied to the gate. Therefore, one of the source and the drain may be referred to as a first pole, and the other may be referred to as a second pole. The transistor of the sub-pixel P may use at least one of a polycrystalline silicon semiconductor, an amorphous silicon semiconductor, and an oxide semiconductor. The transistor of the sub-pixel P may be a P-type transistor or an N-type transistor, and the sub-pixel P may include both a P-type transistor and an N-type transistor.

[0214] The first viewing angle control transistor Tvc1 includes a semiconductor layer 211 disposed on the upper end of the buffer layer 110, a gate 213, a source 215 and a drain 217. The second viewing angle control transistor Tvc2 includes a semiconductor layer 221 disposed on the buffer layer 110, a gate 223, a source 225 and a drain 227.

[0215] The gate insulating layer 120 may be disposed between the semiconductor layers 211 and 221 and the gates 213 and 223. The interlayer insulating layer 130 may be disposed between the gates 213 and 223 and the source and drain electrodes 215, 217, 225, and 227. The source electrode 215 and the drain electrode 217 of the first viewing angle control transistor Tvc1 may be connected to the source region and the drain region of the semiconductor layer 211 through a contact hole penetrating the interlayer insulating layer 130 and the gate insulating layer 120. The source electrode 225 and the drain electrode 227 of the second viewing angle control transistor Tvc2 may be connected to the source region and the drain region of the semiconductor layer 221 through a contact hole penetrating the interlayer insulating layer 130 and the gate insulating layer 120.

[0216] The semiconductor layers 211 and 221 may include polysilicon, an oxide semiconductor material, or low temperature polysilicon (LPTS). The semiconductor layers 211 and 221 may include at least one selected from IZO (InZnO)-based, IGO (InGaO)-based, ITO (InSnO)-based, IGZO (InGaZnO)-based, IGZTO (InGaZnSnO)-based, GZTO (GaZnSnO)-based, GZO (GaZnO)-based, and ITZO (InSnZnO)-based oxide semiconductor materials. A light blocking layer may be further provided below the semiconductor layers 211 and 221.

[0217] The gate insulating layer 120 may include an inorganic insulating material such as silicon oxide (SiOx) and silicon nitride (SiNx). The gate insulating layer 120 may include a material having a high dielectric constant. For example, the gate insulating layer 120 may include a high-K material such as hafnium oxide (HfO). The gate insulating layer 120 may have a multilayer structure.

[0218] A gate line connected to the gate electrodes 213 and 223 may be disposed on the gate insulating layer 120 .

[0219] The interlayer insulating layer 130 may include an inorganic insulating material such as silicon oxide (SiOx) and silicon nitride (SiNx). The interlayer insulating layer 130 may have a multi-layer structure.

[0220] Data lines and power lines connected to the source electrodes 215 and 225 or the drain electrodes 217 and 227 may be disposed on the interlayer insulating layer 130 .

[0221] The passivation layer 140 and the planarization layer 150 may be stacked on the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2. The passivation layer 140 may include an inorganic insulating material such as silicon oxide (SiOx) and silicon nitride (SiNx). The planarization layer 150 may include an organic insulating material different from the material of the passivation layer 140 and may provide a flat surface.

[0222] A light emitting device layer including the first light emitting device ED1 and the second light emitting device ED2 may be disposed on the planarization layer 150 .

[0223] The first light emitting device ED1 includes a first electrode 311 disposed on the planarization layer 150, a light emitting layer 312 disposed on the first electrode 311, and a second electrode 313 disposed on the light emitting layer 312. The second light emitting device ED2 includes a first electrode 321 disposed on the planarization layer 150, a light emitting layer 322 disposed on the first electrode 321, and a second electrode 323 disposed on the light emitting layer 322. The first light emitting device ED1 and the second light emitting device ED2 disposed in the subpixel P may emit light of the same color.

[0224] The first electrode 311 of the first light emitting device ED1 may be connected to any one of the source 215 and the drain 217 of the first viewing angle control transistor Tvc1 through a contact hole penetrating the planarization layer 150 and the passivation layer 140. The first electrode 321 of the second light emitting device ED2 may be connected to any one of the source 225 and the drain 227 of the second viewing angle control transistor Tvc2 through a contact hole penetrating the planarization layer 150 and the passivation layer 140.

[0225] The first electrodes 311 and 321 may include a conductive material with high reflectivity. The first electrodes 311 and 321 may include metals such as aluminum (Al), silver (Ag), titanium (Ti), and silver palladium copper (APC) alloys. The first electrodes 311 and 321 may also include transparent conductive materials such as indium tin oxide (ITO) or indium zinc oxide (IZO). For example, the first electrodes 311 and 321 may have a multilayer structure Ti / Al / Ti of titanium (Ti) and aluminum (Al), a multilayer structure ITO / Al / ITO of ITO and aluminum (Al), or a multilayer structure ITO / APC / ITO of ITO and APC.

[0226] The light emitting layers 312 and 322 may include a light emitting material layer (EML) including a light emitting material. The light emitting material may include an organic material, an inorganic material, or a mixed material. The light emitting layer 312 of the first light emitting device ED1 and the light emitting layer 322 of the second light emitting device ED2 may be spaced apart from each other. Therefore, light emission due to leakage current may be prevented.

[0227] The light emitting layers 312 and 322 may have a multi-layer structure. For example, the light emitting layers 312 and 322 may further include at least one of a hole injection layer (HIL), a hole transport layer (HTL), and an electron injection layer (EIL).

[0228] The second electrodes 313 and 323 may include a conductive material that can transmit light. The second electrodes 313 and 323 may include a transparent conductive material such as ITO or IZO. The second electrodes 313 and 323 may include aluminum (Al), magnesium (Mg), silver (Ag) or an alloy thereof, and may have a thin thickness that can transmit light. Therefore, the light generated in each light-emitting layer 312 and 322 can be emitted by the second electrodes 313 and 323.

[0229] The first electrode 311 of the first light emitting device ED1 may be spaced apart from the first electrode 321 of the second light emitting device ED2, and a bank insulating layer 160 may be provided between the first electrodes 311 and 321. The bank insulating layer 160 may cover an edge of each of the first electrodes 311 and 321. The bank insulating layer 160 may include an organic insulating material. The bank insulating layer 160 may include an organic material different from that of the planarization layer 150, and may have a single-layer or double-layer structure.

[0230] The bank insulating layer 160 may include an opening portion through which the first electrode 311 of the first light emitting device ED1 is exposed, and light may be output through the opening portion. The light emitting layer 312 and the second electrode 313 of the first light emitting device ED1 may be stacked on the first electrode 311 exposed through the opening portion of the bank insulating layer 160.

[0231] The bank insulating layer 160 may include an opening portion through which the first electrode 321 of the second light emitting device ED2 is exposed, and light may be output through the opening portion. The bank insulating layer 160 may include at least two opening portions disposed on the first electrode 321, so that at least two second light emitting devices ED2 may be formed.

[0232] The light emitting layer 322 and the second electrode 323 of the second light emitting device ED2 may be stacked on the first electrode 321 exposed through the opening portion of the bank insulating layer 160. The light emitting layer 322 and the second electrode 323 of the second light emitting device ED2 may overlap the first electrode 321. In the second light emitting unit LU2, at least two second light emitting devices ED2 are independently arranged and spaced apart from each other by the bank insulating layer 160, but the second light emitting devices ED2 may share the first electrode 321, the light emitting layer 322, and the second electrode 323. Therefore, the light emitting efficiency of the second light emitting device ED2 may be improved. The size of the second light emitting device ED2 may be smaller than that of the first light emitting device ED1.

[0233] The second electrode 313 of the first light emitting device ED1 may be a common electrode electrically connected to the second electrode 323 of the second light emitting device ED2 .

[0234] The encapsulation layer 800 may be disposed on the light emitting device layer including the first light emitting device ED1 and the second light emitting device ED2. The encapsulation layer 800 may prevent the light emitting devices ED1 and ED2 from being damaged by impact and moisture from the outside. The encapsulation layer 800 may have a multilayer structure. For example, the encapsulation layer 800 may include a first encapsulation layer 810, a second encapsulation layer 820, and a third encapsulation layer 830, but is not limited thereto. The first encapsulation layer 810, the second encapsulation layer 820, and the third encapsulation layer 830 may include an insulating material. The second encapsulation layer 820 may include a material different from that of the first encapsulation layer 810 and the third encapsulation layer 830. For example, the first encapsulation layer 810 and the third encapsulation layer 830 may be an inorganic encapsulation layer including an inorganic insulating material, and the second encapsulation layer 820 may include an organic encapsulation layer including an organic insulating material. Therefore, the light emitting devices ED1 and ED2 may be more effectively prevented from being damaged by impact and moisture from the outside.

[0235] A lens layer including the first lens LZ1 and the second lens LZ2 may be disposed on the encapsulation layer 800 .

[0236] The first lens LZ1 may be disposed at an upper end of the first light emitting device ED1 in the first light emitting unit LU1. The first lens LZ1 does not limit the path of the light generated in the first light emitting device ED1 in the left-right direction. Therefore, the first lens LZ1 may output light having a wide viewing angle in the left-right direction. For example, the first lens LZ1 does not limit the path of the light emitted from the first light emitting device ED1 within a specific angle in the left-right direction. Therefore, the first lens LZ1 may output light having a wide viewing angle in the left-right direction. In addition, the first lens LZ1 may limit the path of the light generated in the first light emitting device ED1 within a certain angle in the up-down direction, so that light having a narrow viewing angle in the up-down direction may be output.

[0237] The second lens LZ2 may be disposed at an upper end of the second light-emitting device ED2 in the second light-emitting unit LU2. The second lens LZ2 limits the path of light generated in the second light-emitting device ED2 to the left and right directions. Therefore, the second lens LZ2 may output light having a narrow viewing angle in the left and right directions. For example, the second lens LZ2 limits the path of light emitted from the second light-emitting device ED2 to the left and right directions. Therefore, the second lens LZ2 may output light having a narrow viewing angle in the left and right directions. In addition, the second lens LZ2 may limit the path of light generated in the second light-emitting device ED2 to a specific angle in the up and down directions, thereby being able to output light having a narrow viewing angle in the up and down directions.

[0238] The lens passivation layer 900 may be disposed on the first lens LZ1 and the second lens LZ2 of each sub-pixel region. The lens passivation layer 900 may include an organic insulating material. The refractive index of the lens passivation layer 900 may be less than the refractive index of the first lens LZ1 and the refractive index of the second lens LZ2. Therefore, the light passing through the first lens LZ1 and the second lens LZ2 cannot be reflected toward the direction of the substrate 101.

[0239] Fig.13 is an exemplary timing diagram for explaining a basic driving method of a light emitting display device according to an embodiment of the present disclosure.

[0240] In the light-emitting display device according to the present disclosure, the pixel driving circuit PDC may be driven in a state where one of the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 provided in the sub-pixel P is turned on. Therefore, in each sub-pixel P, only the first light-emitting device ED1 connected to the first viewing angle control transistor Tvc1 may output light, or only the second light-emitting device ED2 connected to the second viewing angle control transistor Tvc2 may output light.

[0241] Light output from the first light emitting device ED1 may have a first viewing angle (wide viewing angle), and light output from the second light emitting device ED2 may have a second viewing angle (narrow viewing angle).

[0242] Therefore, an image with a first viewing angle (wide viewing angle) can be displayed in a light emitting area where light is output only from the first light emitting device ED1, and an image with a second viewing angle (narrow viewing angle) can be displayed in a light emitting area where light is output only from the second light emitting device ED2.

[0243] The pixel driving circuit PDC applied to the light-emitting display device according to the present disclosure may include a light-emitting control unit ECU and a viewing angle control unit VCU, as shown in FIG. Figure 2 as described.

[0244] The viewing angle control unit VCU may include a first viewing angle control transistor Tvc1 connected to the first light emitting device ED1 and a second viewing angle control transistor Tvc2 connected to the second light emitting device ED2. The gate of the first viewing angle control transistor Tvc1 may be connected to the first control signal line CL1, and the gate of the second viewing angle control transistor Tvc2 may be connected to the second control signal line CL2.

[0245] In this case, the polarity type of the first viewing angle control transistor Tvc1 may be the same as the polarity type of the second viewing angle control transistor Tvc2. For example, when the first viewing angle control transistor Tvc1 is a P-type transistor, Figure 2 As shown, the second viewing angle control transistor Tvc2 may also be a P-type transistor.

[0246] The light emission control unit ECU may perform a function of supplying current to the first viewing angle control transistor Tvc1 or the second viewing angle control transistor Tvc2. To this end, the light emission control unit ECU may be formed as Figure 2 The structure shown can be changed to Figure 2 Various structures other than those shown.

[0247] Furthermore, a driving method for turning on the driving transistor Tdr included in the light emission control unit ECU to supply current to the first viewing angle control transistor Tvc1 or the second viewing angle control transistor Tvc2 may also be changed in various ways.

[0248] Therefore, in the following, reference will be made to Figure 2 The pixel driving circuit PDC and Fig.13 The timing diagram shown briefly describes a basic driving method of a light emitting display device according to the present disclosure.

[0249] In particular, hereinafter, reference will be made to the eighth light emitting area EA8 (eg, the eighth light emitting area EA9) which is switched from the privacy mode (PM) of outputting the general image IM2 having the second viewing angle (narrow viewing angle) to the sharing mode (SM) of outputting the emergency information image IM4 having the first viewing angle (wide viewing angle). Fig. 7E ) briefly describes a basic driving method of a light-emitting display device according to the present disclosure.

[0250] First, for example, when the eighth light emitting area EA8 is driven in the privacy mode (PM), the following Fig.13 The first control signal CS1 with a high level is provided to the gate of the first viewing angle control transistor Tvc1 of the sub-pixel P disposed in the eighth light emitting area EA8. Fig.13 The second control signal CS2 shown having a low level may be supplied to the gate of the second viewing angle control transistor Tvc2 of the sub-pixel P disposed in the eighth light emitting area EA8.

[0251] That is, the level of the first control signal CS1 provided to the subpixel P disposed in the eighth emission area EA8 is different from the level of the second control signal CS2 provided to the subpixel P disposed in the eighth emission area EA8. For example, when the first control signal CS1 has a high level, the second control signal CS2 has a low level.

[0252] In this case, if Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 disposed in the sub-pixel P may be P-type transistors.

[0253] Therefore, when the eighth light-emitting area EA8 is driven in the privacy mode (PM), the first viewing angle control transistor Tvc1 set in the sub-pixel P of the eighth light-emitting area EA8 can be turned off by the first control signal CS1 having a high level, and the second viewing angle control transistor Tvc2 set in the sub-pixel P of the eighth light-emitting area EA8 can be turned on by the second control signal CS2 having a low level.

[0254] Next, if Fig.13 As shown, when the reference control signal RCS having a low level, the selection signal GS having a high level, and the light-emitting signal EM having a low level are provided to the k-th pixel row line (k is a natural number less than or equal to g) set in the eighth light-emitting area EA8, the first light-emitting transistor Tsw4a, the second light-emitting transistor Tsw4b, the first reference transistor Tsw2a, the second reference transistor Tsw2b, and the connecting transistor Tsw3 in the sub-pixel P set in the k-th pixel row line may be turned on, and the switch transistor Tsw1 may be turned off. Here, the k-th pixel row line may represent a pixel row line set in the eighth light-emitting area EA8, and in particular, the k-th pixel row line may represent a sub-pixel set along the first direction X in the eighth light-emitting area EA8.

[0255] Therefore, through the first light-emitting transistor Tsw4a, the second light-emitting transistor Tsw4b, the first reference transistor Tsw2a, the second reference transistor Tsw2b and the connecting transistor Tsw3, the reference voltage VREF can be provided to the gate of the driving transistor Tdr, the first electrode (anode) of the first light-emitting device ED1 and the first electrode (anode) of the second light-emitting device ED2.

[0256] Therefore, the gate electrode of the driving transistor Tdr, the first electrode (anode) of the first light emitting device ED1 , and the first electrode (anode) of the second light emitting device ED2 may be initialized by the reference voltage VREF.

[0257] If the second terminal of the first reference transistor Tsw2a is connected to the first terminal of the first viewing angle control transistor Tvc1 and the second terminal of the second reference transistor Tsw2b is connected to the first terminal of the second viewing angle control transistor Tvc2, since the first viewing angle control transistor Tvc1 is turned off, only the second light emitting device ED2 can be initialized by the reference voltage VREF transmitted through the second reference transistor Tsw2b and the second viewing angle control transistor Tvc2.

[0258] Hereinafter, a period during which the reference control signal RCS having a low level, the gate signal GS having a high level, and the light emitting signal EM having a low level are supplied to the k-th pixel row line provided in the eighth light emitting area EA8 is referred to as an initialization period A.

[0259] Next, after the initialization period A, the sampling period B starts.

[0260] In sampling period B, if Fig.13 As shown, when the reference control signal RCS with a low level, the selection signal GS with a low level, and the light-emitting signal EM with a high level are provided to the k-th pixel row line set in the eighth light-emitting area EA8, the switch transistor Tsw1, the first reference transistor Tsw2a, the second reference transistor Tsw2b, and the connection transistor Tsw3 set in the sub-pixel connected to the k-th pixel row line can be turned on, and the first light-emitting transistor Tsw4a and the second light-emitting transistor Tsw4b can be turned off. In this case, the driving transistor Tdr can also be turned on. Since the second light-emitting transistor Tsw4b is turned off, even if the driving transistor Tdr is turned on, the second light-emitting device ED2 is not provided with current through the second viewing angle control transistor Tvc2.

[0261] Therefore, the data voltage Vdata transmitted through the data line DL may be charged to the first terminal of the storage capacitor Cst through the switching transistor Tsw1 .

[0262] In this case, the gate of the driving transistor Tdr, which is the second terminal of the storage capacitor Cst, may be charged with the first voltage VDD and the threshold voltage (Vth) of the driving transistor Tdr.

[0263] Next, after the sampling period B, the light emission period C starts.

[0264] In the light-emitting period C, Fig.13 As shown, when the reference control signal RCS having a high level, the selection signal GS having a high level, and the light-emitting signal EM having a low level are provided to the kth pixel row line set in the eighth light-emitting area EA8, the switching transistor Tsw1, the first reference transistor Tsw2, the second reference transistor Tsw2b, and the connecting transistor Tsw3 set in the sub-pixel P connected to the kth pixel row line can be turned off, and the first light-emitting transistor Tsw4a and the second light-emitting transistor Tsw4b can be turned on.

[0265] Therefore, the first terminal of the storage capacitor Cst may be charged with the reference voltage VREF.

[0266] In this case, a gate voltage (Vg) (eg, Vg=VREF-Vdata+ELVDD+Vth) may be provided to the gate of the driving transistor Tdr as the second terminal of the storage capacitor Cst, and a source voltage (Vs) (eg, Vs=ELVDD) may be provided to the source of the driving transistor Tdr.

[0267] The level of current flowing to the first light emitting device ED1 or the second light emitting device ED2 through the driving transistor Tdr may be proportional to the square of a voltage obtained by subtracting a threshold voltage (Vth) of the driving transistor Tdr from a difference voltage between a gate voltage Vg and a source voltage Vs of the driving transistor Tdr (hereinafter referred to as a gate-source voltage (Vgs)).

[0268] In the above example, the value (Vgs-Vth) obtained by subtracting the threshold voltage (Vth) of the driving transistor Tdr from the gate-source voltage (Vgs) does not include the threshold voltage (Vth) of the driving transistor Tdr, but may include the data voltage Vdata and the reference voltage VREF (e.g., Vgs-Vth=[Vref-Vdata+ELVDD+Vth]-[ELVDD]-[Vth]=VREF-Vdata). Here, regardless of the threshold voltage (Vth) of the driving transistor Tdr, the reference voltage VREF is a constant voltage.

[0269] Therefore, the threshold voltage (Vth) of the driving transistor Tdr does not affect the level of current flowing through the driving transistor Tdr, and the data voltage Vdata and the reference voltage VREF may affect the level of current flowing through the driving transistor Tdr.

[0270] Therefore, even when the driving transistor Tdr is degraded and thus the threshold voltage (Vth) of the driving transistor Tdr is changed, the first light emitting device ED1 or the second light emitting device ED2 may output light having brightness corresponding to the data voltage Vdata.

[0271] In this case, since the second viewing angle control transistor Tvc2 connected only to the second light-emitting device ED2 is turned on by the second control signal CS2 with a low level in the privacy mode (PM), only light with a second viewing angle (narrow viewing angle) can be output from the sub-pixel P of the kth pixel row line set in the eighth light-emitting area EA8.

[0272] That is, the light having the second viewing angle may be output from the sub-pixel P disposed in the eighth light emitting area EA8. Fig. 7A As shown, a general image IM2 having a second viewing angle (narrow viewing angle) may be displayed in the eighth light emitting area EA8.

[0273] The general image IM2 with the second viewing angle (narrow viewing angle) is visible only to users (eg, passengers) at specific locations. Therefore, as described above, the mode may be a privacy mode (PM).

[0274] When the first control signal CS1 having a high level and the second control signal CS2 having a low level are supplied to the eighth light emitting area EA8, the above process may be repeated in all pixel row lines provided in the eighth light emitting area EA8.

[0275] Next, if an emergency information image IM4 having a first viewing angle (wide viewing angle) is received in the privacy mode (PM) displaying the general image IM2 having a second viewing angle (narrow viewing angle), the control driver 400 may Fig.13 The first control signal having a low level and the second control signal having a high level are shown to be supplied to the sub-pixel P provided in the eighth light emitting area EA8.

[0276] In this case, if Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 disposed in the sub-pixel P may be P-type transistors.

[0277] Therefore, the first viewing angle control transistor Tvc1 disposed in the subpixel P of the eighth light emitting area EA8 may be turned on by the first control signal CS1 having a low level, and the second viewing angle control transistor Tvc2 may be turned off by the second control signal CS2 having a high level.

[0278] Next, the initialization period A and the sampling period B may be performed with respect to the k-th pixel row line provided in the eighth light emitting area EA8.

[0279] That is, for the k-th pixel row line, the same initialization period A and sampling period B as those described in the privacy mode (PM) may be performed.

[0280] Therefore, the driving transistor Tdr disposed in the k-th pixel row line may be initialized and the data voltage Vdata may be provided to the sub-pixel P.

[0281] Finally, after the sampling period B, the light emission period C starts.

[0282] In the light-emitting period C, if Fig.13 As shown, when the reference control signal RCS having a high level, the selection signal GS having a high level, and the light-emitting signal EM having a low level are provided to the kth pixel row line set in the eighth light-emitting area EA8, the switching transistor Tsw1, the first reference transistor Tsw2a, the second reference transistor Tsw2b, and the connecting transistor Tsw3 set in the sub-pixel P connected to the kth pixel row line can be turned off, and the first light-emitting transistor Tsw4a and the second light-emitting transistor Tsw4b can be turned on.

[0283] Therefore, current flows to the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 through the driving transistor Tdr.

[0284] In this case, in the sharing mode (SM), since the first viewing angle control transistor Tvc1 connected only to the first light-emitting device ED1 is turned on by the first control signal CS1 having a low level, only light with a first viewing angle (wide viewing angle) can be output from the sub-pixel P connected to the k-th pixel row line set in the eighth light-emitting area EA8.

[0285] That is, light having the first viewing angle may be output from the sub-pixel P disposed in the eighth light emitting area EA8, and thus, the emergency information image IM4 having the first viewing angle (wide viewing angle) may be displayed in the eighth light emitting area EA8. Fig. 7E shown.

[0286] The emergency information image IM4 with the first viewing angle (wide viewing angle) can be seen by users at any position, such as a driver and a passenger. Therefore, as described above, the mode can be a sharing mode (SM).

[0287] That is, the mode of the eighth light emitting area EA8 may be changed from the privacy mode (PM) to the sharing mode (SM) by the above method.

[0288] The mode of each of the remaining light emitting areas may also be changed from the privacy mode (PM) to the sharing mode (SM), or from the sharing mode (SM) to the privacy mode (PM) by the same method as described above.

[0289] Fig.14 is an exemplary diagram showing a connection structure of a viewing angle switching unit and a viewing angle control line in a light emitting display device according to an embodiment of the present disclosure, Fig.15 It is shown Fig.14 An exemplary diagram of the structure of the perspective switching unit shown in FIG. Fig.16 It is shown Fig.14 Another exemplary diagram of the structure of the perspective switching unit shown, and Fig.17 It is shown that the application Fig.14 1 is an exemplary diagram of a viewing angle control signal, a first control signal, and a second control signal of a light-emitting display device shown in FIG. Fig.14 Specifically shows Figure 1 The structure of the light-emitting display panel 100 is shown, and Fig.15 and Fig.16 Specifically shows Fig.14 The detailed structure of the perspective switching unit is shown.

[0290] In addition, Fig.14 In the embodiment, different reference numerals are assigned to the 12 viewing angle switching units 700 to distinguish the 12 viewing angle switching units 700. For example, the first viewing angle switching unit corresponding to the first light emitting area EA1 is denoted by reference numeral 700a, and the twelfth viewing angle switching unit corresponding to the twelfth light emitting area EA12 is denoted by reference numeral 700l.

[0291] In the following description, the following description will be omitted or briefly described with reference to Figures 1 to 13 The details described are the same or similar to those described herein. Figures 1 to 17 A method of driving only the first light emitting unit LU1 or only the second light emitting unit LU2 in each light emitting area is described.

[0292] As described above, the first viewing angle control transistor Tvc1 may be connected between the driving transistor Tdr that controls the level of current provided to the first light emitting unit LU1 (or the second light emitting unit LU2) and the first light emitting unit LU1, and the second viewing angle control transistor Tvc2 may be connected between the driving transistor Tdr and the second light emitting unit LU2.

[0293] In this case, if Figure 2 As shown, the second light emitting transistor Tsw4b for controlling the light emitting timing of the first light emitting device ED1 (or the second light emitting device ED2) may also be disposed between the driving transistor Tdr and the first viewing angle control transistor Tvc1 (or the second viewing angle control transistor Tvc2).

[0294] The first light emitting unit LU1 may include a first light emitting device ED1 driven by a first viewing angle control transistor Tdr and a first lens LZ1 disposed on the first light emitting device ED1. In addition, the second light emitting unit LU2 may include a second light emitting device ED2 driven by a second viewing angle control transistor Tvc2 and a second lens LZ2 disposed on the second light emitting device ED2.

[0295] The display area DA of the light-emitting display panel 100 may be divided into at least two light-emitting areas along a first direction X, and the display area DA may be divided into at least two light-emitting areas along a second direction Y different from the first direction X. Figure 1 and Fig.14 FIG. 1 shows a light-emitting display panel 100 divided into four light-emitting areas along a first direction X and divided into three light-emitting areas along a second direction Y. That is, in FIG. Figure 1 and Fig.14 , a light-emitting display panel 100 divided into 12 light-emitting areas EA1 to EA12 is shown.

[0296] In this case, the s-1th perspective switching unit connected to the first perspective control transistor Tvc1 and the second perspective control transistor Tvc2 set in the s-1th light-emitting area in the light-emitting area can be connected to the s-1th perspective control line provided with the s-1th perspective control signal, and the sth perspective switching unit connected to the first perspective control transistor Tvc1 and the second perspective control transistor Tvc2 set in the sth light-emitting area in the light-emitting area can be connected to the sth perspective control line provided with the sth perspective control signal.

[0297] That is, the s-1th perspective switching unit in the perspective switching unit 700 can be connected to the first perspective control transistor Tvc1 and the second perspective control transistor Tvc2 set in the s-1th light-emitting area in the light-emitting area, and the sth perspective switching unit in the perspective switching unit 700 can be connected to the first perspective control transistor Tvc1 and the second perspective control transistor Tvc2 set in the sth light-emitting area in the light-emitting area.

[0298] Wherein, s is a natural number, which is less than or equal to the number of light-emitting areas provided in the light-emitting display panel 100. Fig.14 In the illustrated light emitting display panel 100 , m is 12, and s may be any natural number from 1 to 12.

[0299] In addition, the first to twelfth viewing angle switching units 700a to 700l are connected to the first to twelfth viewing angle control lines VCL1 to VCL12, and the first to twelfth viewing angle control lines VCL1 to VCL12 may be connected to the control driver 400 that generates the first to twelfth viewing angle control signals VCS1 to VCS12. That is, each of the viewing angle switching units 700 may be connected to the control driver 400 that controls the viewing angle switching unit 700.

[0300] For example, in the Fig.14 The gate of the first viewing angle control transistor Tvc1 and the gate of the second viewing angle control transistor Tvc2 in the first light emitting area EA1 in the light emitting area shown can be connected to the first viewing angle switching unit 700a provided with the first viewing angle control signal VCS1. In addition, the gate of the first viewing angle control transistor Tvc1 and the gate of the second viewing angle control transistor Tvc2 in the second light emitting area EA2 in the light emitting area can be connected to the second viewing angle switching unit 700b provided with the second viewing angle control signal VCS2. In addition, the gate of the first viewing angle control transistor Tvc1 and the gate of the second viewing angle control transistor Tvc2 in the twelfth light emitting area EA12 in the light emitting area can be connected to the twelfth viewing angle switching unit 700l provided with the twelfth viewing angle control signal VCS12. In addition, the first viewing angle control lines VCL1 to the twelfth viewing angle control lines VCL12 can be connected to the control driver 400 that generates the first viewing angle control signals VCS1 to the twelfth viewing angle control signals VCS12.

[0301] In particular, the first to twelfth viewing angle control lines VCL1 to VCL12 may be connected to first to twelfth viewing angle control signal generators 701 to 712 provided in the control signal generator 420 of the control driver 400, as shown in FIG. Fig.14That is, the first viewing angle control signal generator 701 to the twelfth viewing angle control signal generator 712 can generate the first viewing angle control signal VCS1 to the twelfth viewing angle control signal VCS12.

[0302] Therefore, each of the light emitting areas EA1 to EDA12 can be driven independently. For example, the subpixel P disposed in the first light emitting area EA1 can be driven by the first viewing angle control signal VCS1, the subpixel P disposed in the second light emitting area EA2 can be driven by the second viewing angle control signal VCS2, and the subpixel P disposed in the twelfth light emitting area EA12 can be driven by the twelfth viewing angle control signal VSC12.

[0303] The first to twelfth viewing angle switching units 700a to 701 may be disposed in the non-display area NDA. Fig.14 shown.

[0304] For example, when the first to third light emitting areas EA1 to EA3 are arranged on the left side of the display area DA, as shown in FIG. Fig.14 As shown, the first to third viewing angle switching units 700a to 700c may be disposed in the non-display area NDA disposed on the left side of the display area DA.

[0305] In addition, if Fig.14 As shown, when the tenth to twelfth emission areas EA10 to EA12 are disposed on the right side of the display area DA, the tenth to twelfth viewing angle switching units 700j to 700l may be disposed in the non-display area NDA disposed on the right side of the display area DA.

[0306] In addition, when the fourth to ninth light emitting areas EA4 to EA9 are disposed in the central region with respect to the left and right sides of the display area DA, as shown in FIG. Fig.14 As shown, the fourth to ninth viewing angle switching units 700d to 700i may be disposed in the non-display area NDA disposed on the upper side or the lower side of the display area DA. Fig.14 In the light-emitting display device shown, the control signal generator 420 included in the control driver 400 is disposed at the lower side of the light-emitting display panel. Therefore, in order to minimize the length of the viewing angle control line VCL, the fourth viewing angle switching unit 700d to the ninth viewing angle switching unit 700i may be disposed at the lower side of the display area DA.

[0307] In this case, the first to twelfth viewing angle switching units 700a to 700l are connected to the first to twelfth viewing angle control lines VCL1 to VCL12, and the first to twelfth viewing angle control lines VCL1 to VCL12 may be connected to the control driver 400 that generates the first to twelfth viewing angle control signals VCS1 to VCS12. That is, one viewing angle control line VCL is connected to each of the viewing angle switching units 700.

[0308] In addition, the high voltage line HL and the low voltage line LL may be connected to the first to twelfth viewing angle switching units 700a to 700l, respectively. The high voltage VGH may be supplied to the high voltage line HL through the power supply unit 500, and the low voltage VGL lower than the high voltage VGH may be supplied to the low voltage line LL through the power supply unit 500.

[0309] The high voltage VGH may be a voltage capable of turning off (or on) the first and second viewing angle control transistors Tvc1 and Tvc2, and the low voltage VGL may be a voltage capable of turning on (or off) the first and second viewing angle control transistors Tvc1 and Tvc2.

[0310] For example, Figure 2 As shown, when the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 are formed of P-type transistors, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 may be turned off by the high voltage VGH and may be turned on by the low voltage VGL.

[0311] That is, the voltage for turning on the first and second viewing angle control transistors Tvc1 and Tvc2 and the voltage for turning off the first and second viewing angle control transistors Tvc1 and Tvc2 may vary based on the polarity types of the first and second viewing angle control transistors Tvc1 and Tvc2.

[0312] In the following, Figure 2 As shown, a light-emitting display device including a first viewing angle control transistor Tvc1 and a second viewing angle control transistor Tvc2 formed of a P-type transistor will be described as an example of a light-emitting display device according to an embodiment of the present disclosure. Therefore, the high voltage VGH may be a voltage capable of turning off the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2, and the low voltage VGL may be a voltage capable of turning on the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2.

[0313] In this case, each of the view switching units 700 may include a first switching unit 710 and a second switching unit 720 .

[0314] For example, in the perspective switching unit 700, the sth perspective switching unit (s is a natural number that is less than or equal to the number of light-emitting areas) may include a first switching unit 710 connected to the gate of the first perspective control transistor Tvc1 in the sth light-emitting area in the light-emitting area EA and a second switching unit 720 connected to the gate of the second perspective control transistor Tvc2 in the sth light-emitting area.

[0315] To provide additional description, the first viewing angle switching unit 700a may include a first switching unit 710 connected to the gate of the first viewing angle control transistor Tvc1 set in the first light-emitting area EA1 set in the light-emitting area EA and a second switching unit 720 connected to the gate of the second viewing angle control transistor Tvc2 set in the first light-emitting area EA1.

[0316] In addition, the second viewing angle switching unit 700b may include a first switching unit 710 connected to the gate of the first viewing angle control transistor Tvc1 in the second light emitting area EA2 disposed in the light emitting area EA and a second switching unit 720 connected to the gate of the second viewing angle control transistor Tvc2 disposed in the second light emitting area EA2.

[0317] Therefore, the twelfth viewing angle switching unit 700l may include a first switching unit 710 connected to the gate of the first viewing angle control transistor Tvc1 in the twelfth light-emitting area EA12 set in the light-emitting area EA and a second switching unit 720 connected to the gate of the second viewing angle control transistor Tvc2 set in the twelfth light-emitting area EA12.

[0318] The first switching unit 710 may include a first transistor unit TU1 connected between a first control signal line CL1 and a low voltage line LL, and a first resistance unit RU1 connected between the first control signal line CL1 and a high voltage line HL, the first control signal line CL1 is connected to a gate of a first viewing angle control transistor Tvc1 disposed in the sth light emitting area, the low voltage line LL is provided with a low voltage, and the high voltage line HL is provided with a high voltage VGH higher than the low voltage VGL.

[0319] The second switching unit 720 may include a second transistor unit TU2 connected between a second control signal line CL2 and a high voltage line HL and a second resistance unit RU2 connected between the second control signal line CL2 and a low voltage line LL, wherein the second control signal line CL2 is connected to a gate of a second viewing angle control transistor Tvc2 disposed in the sth light emitting area.

[0320] For example, the first switching units 710 provided in the first to twelfth perspective switching units 700a to 700l may have the same structure, and the second switching units 720 provided in the first to twelfth perspective switching units 700a to 700l may have the same structure.

[0321] In this case, the structure of the first switching unit 710 and the structure of the second switching unit 720 may be formed differently from each other.

[0322] For example, Fig.15 As shown, the first transistor unit TU1 of the first switching unit 710 may include a first control transistor T1. In this case, a gate of the first control transistor T1 may be connected to a viewing angle control line VCL to which a viewing angle control signal VCS is provided, a first terminal of the first control transistor T1 may be connected to a low voltage line LL, and a second terminal of the first control transistor T1 may be connected to the first resistance unit RU1.

[0323] The second transistor unit TU2 of the second switching unit 720 may include a second control transistor T2. In this case, a gate of the second control transistor T2 may be connected to the viewing angle control line VCL, a first terminal of the second control transistor T2 may be connected to the high voltage line HL, and a second terminal of the second control transistor T2 may be connected to the second resistance unit RU2.

[0324] In this case, each of the first resistance unit RU1 and the second resistance unit RU2 provided in the viewing angle switching unit 700 may be formed of a resistor. Fig.15 As shown, the first resistance unit RU1 may include a first resistor R1 disposed between the high voltage line HL and the first control signal line CL1, and the second resistance unit RU2 may include a second resistor R2 disposed between the low voltage line LL and the second control signal line CL2.

[0325] The first resistor R1 and the second resistor R2 can be replaced by a first resistance transistor Tr1 and a second resistance transistor Tr2, such as Fig.16 That is, each of the first resistance transistor Tr1 and the second resistance transistor Tr2 can be used as a resistor.

[0326] In the following, reference will be made to Figures 14 to 17 A method of operating the viewing angle switching unit 700 and a method of driving the light emitting area EA corresponding to the viewing angle switching unit 700 are described. In particular, in the following, as Fig.15 As shown, a viewing angle switching unit 700 including a first control transistor T1 and a second control transistor T2 formed as a P type will be described as an example of the present disclosure.

[0327] First, if Fig.17 As shown, when the viewing angle control signal VCS having a low level is provided through the viewing angle control line VCL, Fig.15 The first control transistor T1 and the second control transistor T2 are shown to be turned on.

[0328] Therefore, the low voltage VGL provided through the first terminal of the first control transistor T1 is provided to the first control signal line CL1 through the first control transistor T1. That is, the first control signal CS1 having a low level is provided to the first control signal line CL1.

[0329] In addition, the high voltage VGH provided through the first terminal of the second control transistor T2 is provided to the second control signal line CL2 through the second control transistor T2. That is, the second control signal CS2 having a high level is provided to the second control signal line CL2.

[0330] In this case, when Fig.15 When the perspective switching unit 700 shown is a first perspective switching unit 700a, the first control signal line CL1 connected to the first perspective switching unit 700a is connected to the gate of the first perspective control transistor Tvc1 set in the first light-emitting area EA1, and the second control signal line CL2 connected to the first perspective switching unit 700a is connected to the gate of the second perspective control transistor Tvc2 set in the first light-emitting area EA1.

[0331] Therefore, the first control signal CS1 having a low level is supplied to the gate of the first viewing angle control transistor Tvc1 disposed in the first light emitting area EA1, and the second control signal CS2 having a high level is supplied to the gate of the second viewing angle control transistor Tvc2 disposed in the first light emitting area EA1.

[0332] like Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 can be formed by P-type transistors. Therefore, when the first viewing angle control transistor Tvc1 is provided with a first control signal CS1 having a low level, the first viewing angle control transistor Tvc1 is turned on. In addition, when the second viewing angle control transistor Tvc2 is provided with a second control signal CS2 having a high level, the second viewing angle control transistor Tvc2 is turned off.

[0333] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions can be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1. That is, in the first light emitting area EA1, only the first light emitting unit LU1 can be driven to output an image having a wide viewing angle.

[0334] Therefore, the mode of the first light emitting area EA1 may be the sharing mode (SM).

[0335] In this case, if Fig.16 As shown, when the first resistance unit RU1 is formed by the first resistance transistor Tr1 and the second resistance unit RU2 is formed by the second resistance transistor Tr2, the gate of the first resistance transistor Tr1 and the gate of the second resistance transistor Tr2 can be connected to the viewing angle control line VCL. The first resistance transistor Tr1 and the second resistance transistor Tr2 can be formed by N-type transistors.

[0336] Therefore, the first resistance transistor Tr1 and the second resistance transistor Tr2 are turned off by the viewing angle control signal VCS having a low level.

[0337] Therefore, as described above, the first control signal line CL1 may be provided with the first control signal CS1 having a low level through the first control transistor T1 , and the second control signal line CL2 may be provided with the second control signal CS2 having a high level through the second control transistor T2 .

[0338] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions may be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1.

[0339] That is, the mode of the first light emitting area EA1 may be the sharing mode (SM).

[0340] Secondly, if Fig.17 As shown, when the viewing angle control signal VCS having a high level is provided through the viewing angle control line VCL, Fig.15 The first control transistor T1 and the second control transistor T2 are shown to be turned off.

[0341] Therefore, the high voltage VGH provided through the first resistance unit RU1 is provided to the first control signal line CL1 through the first resistance unit RU1. That is, the first control signal CS1 having a high level is provided to the first control signal line CL1.

[0342] In addition, the low voltage VGL provided through the second resistance unit RU2 is provided to the second control signal line CL2 through the second resistance unit RU2. That is, the second control signal CS2 having a low level is provided to the second control signal line CL2.

[0343] In this case, when Fig.15When the perspective switching unit 700 shown is a first perspective switching unit 700a, the first control signal line CL1 connected to the first perspective switching unit 700a is connected to the gate of the first perspective control transistor Tvc1 set in the first light-emitting area EA1, and the second control signal line CL2 connected to the first perspective switching unit 700a is connected to the gate of the second perspective control transistor Tvc2 set in the first light-emitting area EA1.

[0344] Therefore, the first control signal CS1 having a high level is supplied to the gate of the first viewing angle control transistor Tvc1 disposed in the first light emitting area EA1, and the second control signal CS2 having a low level is supplied to the gate of the second viewing angle control transistor Tvc2 disposed in the first light emitting area EA1.

[0345] like Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 can be formed by P-type transistors. Therefore, when the first viewing angle control transistor Tvc1 is provided with a first control signal CS1 having a high level, the first viewing angle control transistor Tvc1 is turned off. In addition, when the second viewing angle control transistor Tvc2 is provided with a second control signal CS2 having a low level, the second viewing angle control transistor Tvc2 is turned on.

[0346] Therefore, in the first light emitting area EA1, the second light emitting unit LU2 connected to the second viewing angle control transistor Tvc2 can output an image with a narrow viewing angle in the left and right directions. That is, in the first light emitting area EA1, only the second light emitting unit LU2 can be driven to output an image with a narrow viewing angle.

[0347] Therefore, the mode of the first light emitting area EA1 may be a privacy mode (PM).

[0348] In this case, if Fig.16 As shown, when the first resistance unit RU1 is formed by the first resistance transistor Tr1 and the second resistance unit RU2 is formed by the second resistance transistor Tr2, the gate of the first resistance transistor Tr1 and the gate of the second resistance transistor Tr2 are connected to the viewing angle control line VCL. The first resistance transistor Tr1 and the second resistance transistor Tr2 may be formed by N-type transistors.

[0349] Therefore, the first resistance transistor Tr1 and the second resistance transistor Tr2 are turned on by the viewing angle control signal VCS having a high level.

[0350] Therefore, as described above, the first control signal CS1 having a high level may be provided to the first control signal line CL1 through the first resistance transistor Tr1, and the second control signal CS2 having a low level may be provided to the second control signal line CL2 through the second resistance transistor Tr2.

[0351] Therefore, in the first light emitting area EA1, an image having a narrow viewing angle in the left and right directions may be output through the second light emitting unit LU2 connected to the second viewing angle control transistor Tvc2.

[0352] That is, the mode of the first light emitting area EA1 may be a privacy mode (PM).

[0353] The above operation method can also be independently performed in the second to twelfth viewing angle switching units 700b to 7001. Therefore, an image with a wide viewing angle or an image with a narrow viewing angle can be output in each of the second to twelfth light emitting areas EA2 to EA12.

[0354] Fig.18 is another exemplary diagram showing a connection structure of a viewing angle switching unit and a viewing angle control line in a light emitting display device according to an embodiment of the present disclosure, Fig.19 It is shown Fig.18 An exemplary diagram of the structure of the perspective switching unit shown in FIG. Fig. 20 It is shown Fig.18 Another exemplary diagram of the structure of the perspective switching unit shown, Fig.21 It is shown Fig.18 Another exemplary diagram of the structure of the perspective switching unit shown, and Fig. 22 It is shown that the application Fig.18 1 is an exemplary diagram of a viewing angle control signal, a first control signal, and a second control signal of a light-emitting display device shown in FIG. Fig.18 Specifically shows Figure 1 The structure of the light-emitting display panel 100 is shown, and Figures 19 to 21 Specifically shows Fig.18 The detailed structure of the perspective switching unit is shown.

[0355] In addition, Fig.18 , different reference numerals are assigned to the 12 viewing angle switching units 700 to distinguish the 12 viewing angle switching units 700. For example, the first viewing angle switching unit corresponding to the first light emitting area EA1 is indicated by reference numeral 700a, and the twelfth viewing angle switching unit corresponding to the twelfth light emitting area EA12 is indicated by reference numeral 7001.

[0356] In the following description, the following description will be omitted or briefly described with reference to Figures 1 to 17 The details described are the same or similar to those described herein. Figures 1 to 22A method of driving only the first light emitting unit LU1 or only the second light emitting unit LU2 in each of the light emitting areas is described. As described above, the first viewing angle control transistor Tvc1 may be connected between the driving transistor Tdr that controls the level of current supplied to the first light emitting unit LU1 (or the second light emitting unit LU2) and the first light emitting unit LU1, and the second viewing angle control transistor Tvc2 may be connected between the driving transistor Tdr and the second light emitting unit LU2.

[0357] In this case, if Figure 2 As shown, the second light emitting transistor Tsw4b for controlling the light emitting timing of the first light emitting device ED1 (or the second light emitting device ED2) may also be disposed between the driving transistor Tdr and the first viewing angle control transistor Tvc1 (or the second viewing angle control transistor Tvc2).

[0358] The first light emitting unit LU1 may include a first light emitting device ED1 driven by a first viewing angle control transistor Tdr and a first lens LZ1 disposed on the first light emitting device ED1. In addition, the second light emitting unit LU2 may include a second light emitting device ED2 driven by a second viewing angle control transistor Tvc2 and a second lens LZ2 disposed on the second light emitting device ED2.

[0359] The display area DA of the light-emitting display panel 100 may be divided into at least two light-emitting areas along a first direction X, and the display area DA may be divided into at least two light-emitting areas along a second direction Y different from the first direction X. Figure 1 and Fig.18 FIG. 1 shows a light-emitting display panel 100 divided into four light-emitting areas along a first direction X and divided into three light-emitting areas along a second direction Y. That is, in FIG. Figure 1 and Fig.18 , a light-emitting display panel 100 divided into 12 light-emitting areas EA1 to EA12 is shown.

[0360] In this case, the s-1th perspective switching unit connected to the first perspective control transistor Tvc1 and the second perspective control transistor Tvc2 set in the s-1th light-emitting area in the light-emitting area can be connected to the s-1th perspective control line provided with the s-1th perspective control signal, and the sth perspective switching unit connected to the first perspective control transistor Tvc1 and the second perspective control transistor Tvc2 set in the sth light-emitting area in the light-emitting area can be connected to the sth perspective control line provided with the sth perspective control signal.

[0361] That is, the s-1th perspective switching unit in the perspective switching unit 700 can be connected to the first perspective control transistor Tvc1 and the second perspective control transistor Tvc2 set in the s-1th light-emitting area in the light-emitting area, and the sth perspective switching unit in the perspective switching unit 700 can be connected to the first perspective control transistor Tvc1 and the second perspective control transistor Tvc2 set in the sth light-emitting area in the light-emitting area.

[0362] Here, s is a natural number that is less than or equal to the number of light-emitting areas provided in the light-emitting display panel 100. Fig.18 In the illustrated light emitting display panel 100 , m is 12, and s may be any natural number from 1 to 12.

[0363] In addition, each of the first to twelfth viewing angle switching units 700a to 700l is connected to two viewing angle control lines VCLX and VCLY, and the viewing angle control lines VCLX1, VCLX2, VCLX3, VCLX4, VCLY1, VCLY2, and VCLY3 may be connected to the control driver 400 that generates viewing angle control signals VCSX1, VCSX2, VCSX3, VCSX4, VCSY1, VCSY2, and VCSY3. That is, each of the viewing angle switching units 700 may be connected to the control driver 400 that controls the viewing angle switching unit 700.

[0364] For example, Fig.18 The gate of the first viewing angle control transistor Tvc1 and the gate of the second viewing angle control transistor Tvc2 provided in the first light emitting area EA1 of the light emitting areas shown can be connected to the first viewing angle switching unit 700a to which the first viewing angle control signals VCSX1 and VCSY1 are provided. In addition, Fig.18 The gates of the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 provided in the second light emitting area EA2 of the light emitting area shown can be connected to the second viewing angle switching unit 700b provided with the second viewing angle control signals VCSX1 and VCSY2. In addition, the gates of the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 provided in the twelfth light emitting area EA12 can be connected to the twelfth viewing angle switching unit 700l provided with the twelfth viewing angle control signals VCSX4 and VCSY3.

[0365] In addition, the viewing angle control lines VCLX1 , VCLX2 , VCLX3 , VCLX4 , VCLY1 , ​​VCLY2 , and VCLY3 may be connected to a control driver 400 that generates viewing angle control signals VCSX1 , VCSX2 , VCSX3 , VCSX4 , VCSY1 , VCSY2 , and VCSY3 .

[0366] In particular, the viewing angle control lines VCLX1, VCLX2, VCLX3, VCLX4, VCLY1, VCLY2, and VCLY3 may be connected to viewing angle control signal generators 701 to 707 provided in the control signal generator 420 of the control driver 400, such as Fig.18 That is, the first viewing angle control signal generator 701 to the seventh viewing angle control signal generator 707 can generate viewing angle control signals VCSX1, VCSY1, VCSX2, VCSY2, VCSX3, VCSX4 and VCSY3.

[0367] In this case, the viewing angle control signal generated by each of the viewing angle control signal generators 701 to 707 is not transmitted to one viewing angle switching unit 700, but may be transmitted to at least one viewing angle switching unit based on the number of light emitting areas provided along the X-axis and the Y-axis.

[0368] For example, when 12 light emitting areas EA1 to EA12 are provided in the light emitting display panel 100, Fig.18 As shown, the coordinates (X, Y) of the 12 light-emitting areas EA1 to EA12 may be (1, 1), (1, 2), (1, 3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3), (4, 1), (4, 2) and (4, 3).

[0369] In this case, four X coordinates and three Y coordinates may be generated.

[0370] To this end, four X-coordinate viewing angle control signals VCSX1 , VCSX2 , VCSX3 , and VCSX4 and three Y-coordinate viewing angle control signals VCSY1 , VCSY2 , and VCSY3 may be generated.

[0371] For example, the first X-coordinate viewing angle control signal VCSX1 generated by the first viewing angle control signal generator 701 may be transmitted to the first viewing angle switching unit 700a, the second viewing angle switching unit 700b, and the third viewing angle switching unit 700c through the first X-coordinate viewing angle control line VCLX1. The first viewing angle switching unit 700a, the second viewing angle switching unit 700b, and the third viewing angle switching unit 700c may be connected to the first light-emitting area EA1, the second light-emitting area EA2, and the third light-emitting area EA3. In addition, the X coordinate of each of the first light-emitting area EA1, the second light-emitting area EA2, and the third light-emitting area EA3 is 1.

[0372] Further, the first Y-coordinate viewing angle control signal VCSY1 generated by the second viewing angle control signal generator 702 can be transmitted to the first viewing angle switching unit 700a, the fourth viewing angle switching unit 700d, the seventh viewing angle switching unit 700g, and the tenth viewing angle switching unit 700j through the first Y-coordinate viewing angle control line VCLY1. The first viewing angle switching unit 700a, the fourth viewing angle switching unit 700d, the seventh viewing angle switching unit 700g, and the tenth viewing angle switching unit 700j can be connected to the first light-emitting area EA1, the fourth light-emitting area EA4, the seventh light-emitting area EA7, and the tenth light-emitting area EA10. In addition, the Y coordinate of each of the first light-emitting area EA1, the fourth light-emitting area EA4, the seventh light-emitting area EA7, and the tenth light-emitting area EA10 is 1.

[0373] In addition, the third X-coordinate viewing angle control signal VCSX3 generated by the fifth viewing angle control signal generator 705 can be transmitted to the seventh viewing angle switching unit 700g, the eighth viewing angle switching unit 700h, and the ninth viewing angle switching unit 700i through the third X-coordinate viewing angle control line VCLX3. The seventh viewing angle switching unit 700g, the eighth viewing angle switching unit 700h, and the ninth viewing angle switching unit 700i can be connected to the seventh light-emitting area EA7, the eighth light-emitting area EA8, and the ninth light-emitting area EA9. In addition, the X coordinate of each of the seventh light-emitting area EA7, the eighth light-emitting area EA8, and the ninth light-emitting area EA9 is 3.

[0374] In addition, the third Y-coordinate viewing angle control signal VCSY3 generated by the seventh viewing angle control signal generator 707 can be transmitted to the third viewing angle switching unit 700c, the sixth viewing angle switching unit 700f, the ninth viewing angle switching unit 700i, and the twelfth viewing angle switching unit 700l through the third Y-coordinate viewing angle control line VCLY3. The third viewing angle switching unit 700c, the sixth viewing angle switching unit 700f, the ninth viewing angle switching unit 700i, and the twelfth viewing angle switching unit 700l can be connected to the third light-emitting area EA3, the sixth light-emitting area EA6, the ninth light-emitting area EA9, and the twelfth light-emitting area EA12. In addition, the Y coordinate of each of the third light-emitting area EA3, the sixth light-emitting area EA6, the ninth light-emitting area EA9, and the twelfth light-emitting area EA12 is 3.

[0375] That is, each of the viewing angle switching units may be connected to one X-coordinate viewing angle control line VCLX and one Y-coordinate viewing angle control line VCLY, and may be driven by one X-coordinate viewing angle control signal VCSX and one Y-coordinate viewing angle control signal VCSY.

[0376] Therefore, each of the light-emitting areas EA1 to EA12 can be driven independently. For example, the sub-pixel P disposed in the first light-emitting area EA1 can be driven by the first X-coordinate viewing angle control signal VCSX1 and the first Y-coordinate viewing angle control signal VCSY1, the sub-pixel P disposed in the second light-emitting area EA2 can be driven by the first X-coordinate viewing angle control signal VCSX1 and the second Y-coordinate viewing angle control signal VCSY2, and the sub-pixel P disposed in the twelfth light-emitting area EA12 can be driven by the fourth X-coordinate viewing angle control signal VCSX4 and the third Y-coordinate viewing angle control signal VCSY3.

[0377] The first to twelfth viewing angle switching units 700a to 701 may be disposed in the non-display area NDA. Fig.18 shown.

[0378] For example, when the first to third light emitting areas EA1 to EA3 are arranged on the left side of the display area DA, as shown in FIG. Fig.18 As shown, the first to third viewing angle switching units 700a to 700c may be disposed in the non-display area NDA disposed on the left side of the display area DA.

[0379] In addition, if Fig.18 As shown, when the tenth to twelfth emission areas EA10 to EA12 are disposed on the right side of the display area DA, the tenth to twelfth viewing angle switching units 700j to 700l may be disposed in the non-display area NDA disposed on the right side of the display area DA.

[0380] In addition, when the fourth to ninth light emitting areas EA4 to EA9 are disposed in the central region with respect to the left and right sides of the display area DA, as shown in FIG. Fig.18 As shown, the fourth to ninth viewing angle switching units 700d to 700i may be disposed in the non-display area NDA disposed on the upper side or the lower side of the display area DA. Fig.18 In the light-emitting display device shown in FIG. 1 , the control signal generator 420 included in the control driver 400 is disposed at the lower side of the light-emitting display panel. Therefore, in order to minimize the length of the viewing angle control lines VCLX and VCLY, Fig.14 In the illustrated light-emitting display panel 100 , the fourth to ninth viewing angle switching units 700 d to 700 i may be disposed at the lower side of the display area DA.

[0381] In this case, each of the first to twelfth viewing angle switching units 700a to 700l is connected to one X-coordinate viewing angle control line VCLX and one Y-coordinate viewing angle control line VCLY, and the X-coordinate viewing angle control lines VCLX1, VCLX2, VCLX3, and VCLX4 and the Y-coordinate viewing angle control lines VCLY1, VCLY2, and VCLY3 may be connected to the control driver 400. That is, each of the viewing angle switching units 700 is connected to one X-coordinate viewing angle control line VCLX and one Y-coordinate viewing angle control line VCLY.

[0382] In addition, a high voltage line HL and a low voltage line LL may be connected to each of the first to twelfth viewing angle switching units 700a to 700l. A high voltage VGH may be supplied to the high voltage line HL by the power supply unit 500, and a low voltage VGL lower than the high voltage VGH may be supplied to the low voltage line LL by the power supply unit 500.

[0383] The high voltage VGH may be a voltage capable of turning off (or on) the first and second viewing angle control transistors Tvc1 and Tvc2, and the low voltage VGL may be a voltage capable of turning on (or off) the first and second viewing angle control transistors Tvc1 and Tvc2.

[0384] For example, Figure 2 As shown, when the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 are formed of P-type transistors, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 may be turned off by the high voltage VGH and may be turned on by the low voltage VGL.

[0385] That is, the voltage for turning on the first and second viewing angle control transistors Tvc1 and Tvc2 and the voltage for turning off the first and second viewing angle control transistors Tvc1 and Tvc2 may vary based on the polarity types of the first and second viewing angle control transistors Tvc1 and Tvc2.

[0386] In the following, Figure 2 As shown, a light-emitting display device including a first viewing angle control transistor Tvc1 and a second viewing angle control transistor Tvc2 formed of a P-type transistor will be described as an example of a light-emitting display device according to the present disclosure. Therefore, the high voltage VGH may be a voltage capable of turning off the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2, and the low voltage VGL may be a voltage capable of turning on the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2.

[0387] In this case, each of the view switching units 700 may include a first switching unit 710 and a second switching unit 720 .

[0388] For example, in the perspective switching unit 700, the sth perspective switching unit (s is a natural number that is less than or equal to the number of light-emitting areas) may include a first switching unit 710 connected to the gate of a first perspective control transistor Tvc1 set in the sth light-emitting area in the light-emitting area EA, and a second switching unit 720 connected to the gate of a second perspective control transistor Tvc2 set in the sth light-emitting area.

[0389] To provide additional description, the first viewing angle switching unit 700a may include a first switching unit 710 connected to the gate of the first viewing angle control transistor Tvc1 set in the first light-emitting area EA1 set in the light-emitting area EA and a second switching unit 720 connected to the gate of the second viewing angle control transistor Tvc2 set in the first light-emitting area EA1.

[0390] In addition, the second viewing angle switching unit 700b may include a first switching unit 710 connected to the gate of the first viewing angle control transistor Tvc1 in the second light emitting area EA2 disposed in the light emitting area EA and a second switching unit 720 connected to the gate of the second viewing angle control transistor Tvc2 disposed in the second light emitting area EA2.

[0391] Therefore, the twelfth viewing angle switching unit 700l may include a first switching unit 710 connected to the gate of the first viewing angle control transistor Tvc1 in the twelfth light-emitting area EA12 set in the light-emitting area EA and a second switching unit 720 connected to the gate of the second viewing angle control transistor Tvc2 set in the twelfth light-emitting area EA12.

[0392] The first switching unit 710 may include a first transistor unit TU1 connected between a first control signal line CL1 and a low voltage line LL and a first resistance unit RU1 connected between the first control signal line CL1 and a high voltage line HL, the first control signal line CL1 is connected to a gate of a first viewing angle control transistor Tvc1 disposed in the sth light emitting area, the low voltage line LL is provided with a low voltage, and the high voltage line HL is provided with a high voltage VGH higher than the low voltage VGL.

[0393] The second switching unit 720 may include a second transistor unit TU2 connected between a second control signal line CL2 and a high voltage line HL, and a second resistance unit RU2 connected between the second control signal line CL2 and a low voltage line LL, wherein the second control signal line CL2 is connected to a gate of a second viewing angle control transistor Tvc2 disposed in the sth light emitting area.

[0394] For example, the first switching units 710 provided in the first to twelfth perspective switching units 700a to 700l may have the same structure, and the second switching units 720 provided in the first to twelfth perspective switching units 700a to 700l may have the same structure.

[0395] In this case, the structure of the first switching unit 710 and the structure of the second switching unit 720 may be formed differently from each other.

[0396] For example, Fig.19 As shown, the first transistor unit TU1 of the first switching unit 710 may include a 1a-th control transistor T1a and a 1b-th control transistor T1b.

[0397] In this case, a gate of the 1a-th control transistor T1a is connected to the X-coordinate viewing angle control line VCLX to which the X-coordinate viewing angle control signal VCSX is provided, a first terminal of the 1a-th control transistor T1a is connected to the low voltage line LL, and a second terminal of the 1a-th control transistor T1a is connected to the first resistance unit RU1.

[0398] A gate of the 1bth control transistor T1b is connected to the Y-coordinate viewing angle control line VCLY provided with the Y-coordinate viewing angle control signal VCSY, a first terminal of the 1bth control transistor T1b is connected to the low voltage line LL, and a second terminal of the 1bth control transistor T1b is connected to the first resistance unit RU1.

[0399] The second transistor unit TU2 of the second switching unit 720 may include a 2a-th control transistor T2a and a 2b-th control transistor T2b.

[0400] In this case, a gate of the 2a-th control transistor T2a is connected to the X-coordinate viewing angle control line VCLX, a first terminal of the 2a-th control transistor T2a is connected to the high voltage line HL, and a second terminal of the 2a-th control transistor T2a is connected to the second resistance unit RU2.

[0401] A gate of the 2b-th control transistor T2b is connected to the Y-coordinate viewing angle control line VCLY, a first terminal of the 2b-th control transistor T2b is connected to the high voltage line HL, and a second terminal of the 2b-th control transistor T2b is connected to the second resistance unit RU2.

[0402] In this case, each of the first resistance unit RU1 and the second resistance unit RU2 provided in the viewing angle switching unit 700 may be formed of a resistor. Fig.19As shown, the first resistance unit RU1 may include a first resistor R1 disposed between the high voltage line HL and the first control signal line CL1, and the second resistance unit RU2 may include a second resistor R2 disposed between the low voltage line LL and the second control signal line CL2.

[0403] The first resistor R1 and the second resistor R2 can be replaced by a first resistance transistor Tr1 and a second resistance transistor Tr2, such as Fig. 20 That is, each of the first resistance transistor Tr1 and the second resistance transistor Tr2 can be used as a resistor.

[0404] In addition, if Fig.21 As shown, the first resistor R1 may be replaced by a 1a-th resistor transistor Tr1a and a 1b-th resistor transistor Tr1b, and the second resistor R2 may be replaced by a 2a-th resistor transistor Tr2a and a 2b-th resistor transistor Tr2b.

[0405] In this case, gates of the 1ath and 2ath resistor transistors Tr1a and Tr2a may be connected to the X-coordinate viewing angle control line VCLX, and gates of the 1bth and 2bth resistor transistors Tr1b and Tr2b may be connected to the Y-coordinate viewing angle control line VCLY.

[0406] In the following, reference will be made to Figures 18 to 22 A method of operating the viewing angle switching unit 700 and a method of driving the light emitting area EA corresponding to the viewing angle switching unit 700 are described. In particular, in the following, Fig.19 As shown, a viewing angle switching unit 700 including a 1a control transistor T1a, a 1b control transistor T1b, a 2a control transistor T2a, and a 2b control transistor T2b formed as a P type will be described as an example of the present disclosure. As described above, since the viewing angle switching units 700 have the same structure, the details described below can be applied to each viewing angle switching unit 700.

[0407] First, if Fig. 22 As shown, when the X-coordinate viewing angle control signal VCSX having a low level is provided through the X-coordinate viewing angle control line VCLX and the Y-coordinate viewing angle control signal VCSY having a low level is provided through the Y-coordinate viewing angle control line VCLY, Fig.19 The 1a-th control transistor T1a, the 1b-th control transistor T1b, the 2a-th control transistor T2a, and the 2b-th control transistor T2b are shown to be turned on.

[0408] Therefore, the low voltage VGL provided through the first terminal of the 1ath control transistor T1a and the first terminal of the 1bth control transistor T1b is provided to the first control signal line CL1 through the 1ath control transistor T1a and the 1bth control transistor T1b. That is, the first control signal CS1 having a low level is provided to the first control signal line CL1.

[0409] In addition, the high voltage VGH provided by the first terminal of the 2a control transistor T2a and the first terminal of the 2b control transistor T2b is provided to the second control signal line CL2 through the 2a control transistor T2a and the 2b control transistor T2b. That is, the second control signal CS2 with a high level is provided to the second control signal line CL2.

[0410] In this case, when Fig.19 When the perspective switching unit 700 shown is a first perspective switching unit 700a, the first control signal line CL1 connected to the first perspective switching unit 700a is connected to the gate of the first perspective control transistor Tvc1 set in the first light-emitting area EA1, and the second control signal line CL2 connected to the first perspective switching unit 700a is connected to the gate of the second perspective control transistor Tvc2 set in the first light-emitting area EA1.

[0411] Therefore, the first control signal CS1 having a low level is supplied to the gate of the first viewing angle control transistor Tvc1 disposed in the first light emitting area EA1, and the second control signal CS2 having a high level is supplied to the gate of the second viewing angle control transistor Tvc2 disposed in the first light emitting area EA1.

[0412] like Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 can be formed by P-type transistors. Therefore, when the first control signal CS1 with a low level is supplied to the first viewing angle control transistor Tvc1, the first viewing angle control transistor Tvc1 is turned on, and when the second control signal CS2 with a high level is supplied to the second viewing angle control transistor Tvc2, the second viewing angle control transistor Tvc2 is turned off.

[0413] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions can be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1. That is, in the first light emitting area EA1, only the first light emitting unit LU1 can be driven to output an image having a wide viewing angle.

[0414] Therefore, the mode of the first light emitting area EA1 may be the sharing mode (SM).

[0415] In this case, if Fig. 20 As shown, when the first resistance unit RU1 is formed by the first resistance transistor Tr1 and the second resistance unit RU2 is formed by the second resistance transistor Tr2, the gate of the first resistance transistor Tr1 and the gate of the second resistance transistor Tr2 are connected to the resistance control line RL. The first resistance transistor Tr1 and the second resistance transistor Tr2 may be formed by P-type transistors, and a resistance control signal having a high level may be input to the resistance control line RL. Therefore, the first resistance transistor Tr1 and the second resistance transistor Tr2 are turned off by the resistance control signal having a high level.

[0416] In addition, if Fig.21 As shown, when the first resistance unit RU1 includes the 1a-th resistance transistor Tr1a and the 1b-th resistance transistor Tr1b and the second resistance unit RU2 includes the 2a-th resistance transistor Tr2a and the 2b-th resistance transistor Tr2b, the gate of the 1a-th resistance transistor Tr1a and the gate of the 2a-th resistance transistor Tr2a can be connected to the X-coordinate viewing angle control line VCLX, and the gate of the 1b-th resistance transistor Tr1b and the gate of the 2b-th resistance transistor Tr2b can be connected to the Y-coordinate viewing angle control line VCLY.

[0417] The 1a-th resistor transistor Tr1a, the 1b-th resistor transistor Tr1b, the 2a-th resistor transistor Tr2a, and the 2b-th resistor transistor Tr2b may be formed of N-type transistors, an X-coordinate viewing angle control signal VCSX having a low level may be input to the X-coordinate viewing angle control line VCLX, and a Y-coordinate viewing angle control signal VCSY having a low level may be input to the Y-coordinate viewing angle control line VCLY.

[0418] Therefore, the 1a-th resistance transistor Tr1a, the 1b-th resistance transistor Tr1b, the 2a-th resistance transistor Tr2a, and the 2b-th resistance transistor Tr2b are turned off by the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY having a low level.

[0419] Therefore, as described above, the first control signal CS1 having a low level can be provided to the first control signal line CL1 through the 1a control transistor T1a and the 1b control transistor T1b, and the second control signal CS2 having a high level can be provided to the second control signal line CL2 through the 2a control transistor T2a and the 2b control transistor T2b.

[0420] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions may be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1.

[0421] That is, the mode of the first light emitting area EA1 may be the sharing mode (SM).

[0422] Secondly, if Fig. 22 As shown, when the X-coordinate viewing angle control signal VCSX having a low level is provided through the X-coordinate viewing angle control line VCLX and the Y-coordinate viewing angle control signal VCSY having a high level is provided through the Y-coordinate viewing angle control line VCLY, Fig.19 As shown, the 1a-th control transistor T1a and the 2a-th control transistor T2a are turned on, while the 1b-th control transistor T1b and the 2b-th control transistor T2b are turned off.

[0423] Therefore, the low voltage VGL provided through the first terminal of the 1a-th control transistor T1a is provided to the first control signal line CL1 through the 1a-th control transistor T1a. That is, the first control signal CS1 having a low level is provided to the first control signal line CL1.

[0424] In addition, the high voltage VGH provided through the first terminal of the 2a-th control transistor T2a is provided to the second control signal line CL2 through the 2a-th control transistor T2a. That is, the second control signal CS2 having a high level is provided to the second control signal line CL2.

[0425] Therefore, the first control signal CS1 having a low level is supplied to the gate of the first viewing angle control transistor Tvc1 disposed in the first light emitting area EA1, and the second control signal CS2 having a high level is supplied to the gate of the second viewing angle control transistor Tvc2 disposed in the first light emitting area EA1.

[0426] like Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 can be formed by P-type transistors. Therefore, when the first control signal CS1 with a low level is supplied to the first viewing angle control transistor Tvc1, the first viewing angle control transistor Tvc1 is turned on, and when the second control signal CS2 with a high level is supplied to the second viewing angle control transistor Tvc2, the second viewing angle control transistor Tvc2 is turned off.

[0427] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions can be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1. That is, in the first light emitting area EA1, only the first light emitting unit LU1 can be driven to output an image having a wide viewing angle.

[0428] Therefore, the mode of the first light emitting area EA1 may be the sharing mode (SM).

[0429] In this case, if Fig. 20As shown, when the first resistance unit RU1 is formed by the first resistance transistor Tr1 and the second resistance unit RU2 is formed by the second resistance transistor Tr2, the gate of the first resistance transistor Tr1 and the gate of the second resistance transistor Tr2 are connected to the resistance control line RL. The first resistance transistor Tr1 and the second resistance transistor Tr2 may be formed by P-type transistors, and a resistance control signal having a high level may be input to the resistance control line RL. Therefore, the first resistance transistor Tr1 and the second resistance transistor Tr2 are turned off by the resistance control signal having a high level.

[0430] In addition, if Fig.21 As shown, when the first resistance unit RU1 includes the 1a-th resistance transistor Tr1a and the 1b-th resistance transistor Tr1b and the second resistance unit RU2 includes the 2a-th resistance transistor Tr2a and the 2b-th resistance transistor Tr2b, the gate of the 1a-th resistance transistor Tr1a and the gate of the 2a-th resistance transistor Tr2a can be connected to the X-coordinate viewing angle control line VCLX, and the gate of the 1b-th resistance transistor Tr1b and the gate of the 2b-th resistance transistor Tr2b can be connected to the Y-coordinate viewing angle control line VCLY.

[0431] The 1a-th resistor transistor Tr1a, the 1b-th resistor transistor Tr1b, the 2a-th resistor transistor Tr2a, and the 2b-th resistor transistor Tr2b may be formed of N-type transistors, an X-coordinate viewing angle control signal VCSX having a low level may be input to the X-coordinate viewing angle control line VCLX, and a Y-coordinate viewing angle control signal VCSY having a high level may be input to the Y-coordinate viewing angle control line VCLY.

[0432] Therefore, the 1a-th and 2a-th resistor transistors Tr1a and Tr2a are turned off by the X-coordinate viewing angle control signal VCSX having a low level, and the 1b-th and 2b-th resistor transistors Tr1b and Tr2b are turned on by the Y-coordinate viewing angle control signal VCSY having a high level.

[0433] Since the 1a-th resistance transistor Tr1a is turned off, the high voltage VGH cannot be supplied to the first control signal line CL1 , and since the 2a-th resistance transistor Tr2a is turned off, the low voltage VGL cannot be supplied to the second control signal line CL2 .

[0434] Therefore, as described above, the first control signal CS1 having a low level may be provided to the first control signal line CL1 through the 1a-th control transistor T1a, and the second control signal CS2 having a high level may be provided to the second control signal line CL2 through the 2a-th control transistor T2a.

[0435] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions may be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1.

[0436] That is, the mode of the first light emitting area EA1 may be the sharing mode (SM).

[0437] Third, if Fig. 22 As shown, when the X-coordinate viewing angle control signal VCSX having a high level is provided through the X-coordinate viewing angle control line VCLX and the Y-coordinate viewing angle control signal VCSY having a low level is provided through the Y-coordinate viewing angle control line VCLY, Fig.19 As shown, the 1a-th control transistor T1a and the 2a-th control transistor T2a are turned off, and the 1b-th control transistor T1b and the 2b-th control transistor T2b are turned on.

[0438] Therefore, the low voltage VGL provided through the first terminal of the 1b-th control transistor T1b is provided to the first control signal line CL1 through the 1b-th control transistor T1b. That is, the first control signal CS1 having a low level is provided to the first control signal line CL1.

[0439] In addition, the high voltage VGH provided through the first terminal of the 2b-th control transistor T2b is provided to the second control signal line CL2 through the 2b-th control transistor T2b. That is, the second control signal CS2 having a high level is provided to the second control signal line CL2.

[0440] Therefore, the first control signal CS1 having a low level is supplied to the gate of the first viewing angle control transistor Tvc1 disposed in the first light emitting area EA1, and the second control signal CS2 having a high level is supplied to the gate of the second viewing angle control transistor Tvc2 disposed in the first light emitting area EA1.

[0441] like Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 can be formed by P-type transistors. Therefore, when the first control signal CS1 with a low level is supplied to the first viewing angle control transistor Tvc1, the first viewing angle control transistor Tvc1 is turned on, and when the second control signal CS2 with a high level is supplied to the second viewing angle control transistor Tvc2, the second viewing angle control transistor Tvc2 is turned off.

[0442] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions can be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1. That is, in the first light emitting area EA1, only the first light emitting unit LU1 can be driven to output an image having a wide viewing angle.

[0443] Therefore, the mode of the first light emitting area EA1 may be the sharing mode (SM).

[0444] In this case, if Fig. 20 As shown, when the first resistance unit RU1 is formed by the first resistance transistor Tr1 and the second resistance unit RU2 is formed by the second resistance transistor Tr2, the gate of the first resistance transistor Tr1 and the gate of the second resistance transistor Tr2 are connected to the resistance control line RL. The first resistance transistor Tr1 and the second resistance transistor Tr2 may be formed by P-type transistors, and a resistance control signal having a high level may be input to the resistance control line RL. Therefore, the first resistance transistor Tr1 and the second resistance transistor Tr2 are turned off by the resistance control signal having a high level.

[0445] In addition, if Fig.21 As shown, when the first resistance unit RU1 includes the 1a-th resistance transistor Tr1a and the 1b-th resistance transistor Tr1b and the second resistance unit RU2 includes the 2a-th resistance transistor Tr2a and the 2b-th resistance transistor Tr2b, the gate of the 1a-th resistance transistor Tr1a and the gate of the 2a-th resistance transistor Tr2a can be connected to the X-coordinate viewing angle control line VCLX, and the gate of the 1b-th resistance transistor Tr1b and the gate of the 2b-th resistance transistor Tr2b can be connected to the Y-coordinate viewing angle control line VCLY.

[0446] The 1a-th resistor transistor Tr1a, the 1b-th resistor transistor Tr1b, the 2a-th resistor transistor Tr2a, and the 2b-th resistor transistor Tr2b may be formed of N-type transistors, an X-coordinate viewing angle control signal VCSX having a high level may be input to the X-coordinate viewing angle control line VCLX, and a Y-coordinate viewing angle control signal VCSY having a low level may be input to the Y-coordinate viewing angle control line VCLY.

[0447] Therefore, the 1a-th and 2a-th resistor transistors Tr1a and Tr2a are turned on by the X-coordinate viewing angle control signal VCSX having a high level, and the 1b-th and 2b-th resistor transistors Tr1b and Tr2b are turned off by the Y-coordinate viewing angle control signal VCSY having a low level.

[0448] Since the 1b-th resistance transistor Tr1b is turned off, the high voltage VGH cannot be provided to the first control signal line CL1, and since the 2b-th resistance transistor Tr2b is turned off, the low voltage VGL cannot be provided to the second control signal line CL2.

[0449] Therefore, as described above, the first control signal CS1 having a low level may be provided to the first control signal line CL1 through the 1b-th control transistor T1b, and the second control signal CS2 having a high level may be provided to the second control signal line CL2 through the 2b-th control transistor T2b.

[0450] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions may be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1.

[0451] That is, the mode of the first light emitting area EA1 may be the sharing mode (SM).

[0452] Fourth, if Fig. 22 As shown, when the X-coordinate viewing angle control signal VCSX having a high level is provided through the X-coordinate viewing angle control line VCLX and the Y-coordinate viewing angle control signal VCSY having a high level is provided through the Y-coordinate viewing angle control line VCLY, Fig.19 The 1a-th control transistor T1a, the 2a-th control transistor T2a, the 1b-th control transistor T1b, and the 2b-th control transistor T2b are turned off.

[0453] Therefore, the high voltage VGH provided through the first resistance unit RU1 is provided to the first control signal line CL1 through the first resistance unit RU1. That is, the first control signal CS1 having a high level is provided to the first control signal line CL1.

[0454] In addition, the low voltage VGL provided through the second resistance unit RU2 is provided to the second control signal line CL2 through the second resistance unit RU2. That is, the second control signal CS2 having a low level is provided to the second control signal line CL2.

[0455] In this case, when Fig.19 When the perspective switching unit 700 shown is a first perspective switching unit 700a, the first control signal line CL1 connected to the first perspective switching unit 700a is connected to the gate of the first perspective control transistor Tvc1 set in the first light-emitting area EA1, and the second control signal line CL2 connected to the first perspective switching unit 700a is connected to the gate of the second perspective control transistor Tvc2 set in the first light-emitting area EA1.

[0456] Therefore, the first control signal CS1 having a high level is supplied to the gate of the first viewing angle control transistor Tvc1 disposed in the first light emitting area EA1, and the second control signal CS2 having a low level is supplied to the gate of the second viewing angle control transistor Tvc2 disposed in the first light emitting area EA1.

[0457] like Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 can be formed by P-type transistors. Therefore, when the first viewing angle control transistor Tvc1 is provided with a first control signal CS1 having a high level, the first viewing angle control transistor Tvc1 is turned off, and when the second viewing angle control transistor Tvc2 is provided with a second control signal CS2 having a low level, the second viewing angle control transistor Tvc2 is turned on.

[0458] Therefore, in the first light emitting area EA1, an image having a narrow viewing angle in the left and right directions can be output through the second light emitting unit LU2 connected to the second viewing angle control transistor Tvc2. That is, in the first light emitting area EA1, only the second light emitting unit LU2 can be driven to output an image having a narrow viewing angle.

[0459] Therefore, the mode of the first light emitting area EA1 may be a privacy mode (PM).

[0460] In this case, if Fig. 20 As shown, when the first resistance unit RU1 is formed by the first resistance transistor Tr1 and the second resistance unit RU2 is formed by the second resistance transistor Tr2, the gate of the first resistance transistor Tr1 and the gate of the second resistance transistor Tr2 are connected to the resistance control line RL. The first resistance transistor Tr1 and the second resistance transistor Tr2 may be formed by P-type transistors, and a resistance control signal having a low level may be input to the resistance control line RL. Therefore, the first resistance transistor Tr1 and the second resistance transistor Tr2 are turned on by the resistance control signal having a low level.

[0461] In addition, if Fig.21 As shown, when the first resistance unit RU1 includes the 1a-th resistance transistor Tr1a and the 1b-th resistance transistor Tr1b and the second resistance unit RU2 includes the 2a-th resistance transistor Tr2a and the 2b-th resistance transistor Tr2b, the gate of the 1a-th resistance transistor Tr1a and the gate of the 2a-th resistance transistor Tr2a can be connected to the X-coordinate viewing angle control line VCLX, and the gate of the 1b-th resistance transistor Tr1b and the gate of the 2b-th resistance transistor Tr2b can be connected to the Y-coordinate viewing angle control line VCLY.

[0462] The 1a-th resistance transistor Tr1a, the 1b-th resistance transistor Tr1b, the 2a-th resistance transistor Tr2a, and the 2b-th resistance transistor Tr2b may be formed of N-type transistors, an X-coordinate viewing angle control signal VCSX having a high level may be provided to the X-coordinate viewing angle control line VCLX, and a Y-coordinate viewing angle control signal VCSY having a high level may be input to the Y-coordinate viewing angle control line VCLY.

[0463] Therefore, the 1a-th resistor transistor Tr1a, the 1b-th resistor transistor Tr1b, the 2a-th resistor transistor Tr2a, and the 2b-th resistor transistor Tr2b are turned on by the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY having a high level. Therefore, as described above, the first control signal CS1 having a high level can be provided to the first control signal line CL1 through the 1a-th resistor transistor Tr1a and the 1b-th resistor transistor Tr1b, and the second control signal CS2 having a low level can be provided to the second control signal line CL2 through the 2a-th resistor transistor Tr2a and the 2b-th resistor transistor Tr2b. Therefore, in the first light-emitting area EA1, an image having a narrow viewing angle in the left and right directions can be output through the second light-emitting unit LU2 connected to the second viewing angle control transistor Tvc2.

[0464] That is, the mode of the first light emitting area EA1 may be a privacy mode (PM).

[0465] The above operation method can also be independently performed in the second to twelfth viewing angle switching units 700b to 7001. Therefore, in each of the second to twelfth light emitting areas EA2 to EA12, an image with a wide viewing angle can be output or an image with a narrow viewing angle can be output.

[0466] Below, we will refer to Figures 14 to 17 The operation method of the light-emitting display device according to the present disclosure is described with reference to the viewing angle switching unit 700 shown in FIG. Figures 14 to 17 Detailed operation methods of each of the perspective switching units 700 are described.

[0467] The operation method described below can be equally applied to Figures 18 to 22 A light-emitting display device with a viewing angle switching unit 700 is described.

[0468] As mentioned above, send to reference Figures 18 to 22 The viewing angle control signals VCSX1, VCSX2, VCSX3, VCSX4, VCSY1, VCSY2 and VCSY3 of the viewing angle switching unit 700 are different from those sent to the reference Figures 14 to 17 The viewing angle control signals VCS1 to VCS12 of the viewing angle switching unit 700 are described in detail. Figures 18 to 22 The first control signal CS1 and the second control signal CS2 generated by the viewing angle switching unit 700 described above are the same as those generated by the reference Figures 14 to 17 The first control signal CS1 and the second control signal CS2 generated by the viewing angle switching unit 700 are described to be the same.

[0469] Therefore, the method of operating the viewing angle switching unit 700 and the method of driving the sub-pixel described below can be equally or similarly applied to the reference Figures 18 to 22 A method of operating the viewing angle switching unit 700 and a method of driving sub-pixels are described.

[0470] First, after the vehicle is started and the vehicle is driven by the driver, a vehicle operation information signal may be transmitted from the external system 600 to the control driver 400 .

[0471] In this case, the first to sixth viewing angle control signal generators 701 to 706 may generate first to sixth viewing angle control signals VCS1 to VCS6 having a low level. The first to sixth viewing angle control signals VCS1 to VCS6 may be transmitted to the first to sixth viewing angle switching units 700a to 700f through the first to sixth viewing angle control lines VCL1 to VCL6.

[0472] In this case, each of the first to sixth viewing angle switching units 700a to 700f may transmit a first control signal CS1 having a low level to the first control signal line CL1 and may transmit a second control signal CS2 having a high level to the second control signal line CL2.

[0473] In the sub-pixels P provided in the first to sixth light-emitting areas EA1 to EA6 corresponding to the first to sixth view switching units 700a to 700f, a first view control transistor Tvc1 connected to the first control signal line CL1 and a second view control transistor Tvc2 connected to the second control signal line CL2 may be provided. Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 may be P-type transistors.

[0474] Therefore, in the sub-pixels P set in the first to sixth emission areas EA1 to EA6, only the first viewing angle control transistor Tvc1 can be turned on by the first control signal CS1 with a low level, and the second viewing angle control transistor Tvc2 can be turned off by the second control signal CS2 with a high level.

[0475] Therefore, in the first to sixth light emitting areas EA1 to EA6, as shown in FIG. Fig. 7A As shown, a first image having a wide viewing angle in the left-right direction, such as a vehicle operation information image, can be displayed by the first light emitting unit LU1. Therefore, both the driver and the passenger can see the vehicle operation information image.

[0476] In other words, the vehicle operation information image IM1 should necessarily be displayed when the vehicle is operated, and in particular, the vehicle operation information image IM1 may have a first viewing angle, such as a wide viewing angle, so that it can be seen by both the driver and the passenger.

[0477] Therefore, the mode of the first to sixth light emitting areas EA1 to EA6 may be a shared mode (SM).

[0478] Next, when the driver operates the vehicle, if the driver or a passenger selects a TV, radio, Internet, or file playback program, a general image signal may be transmitted from the external system 600 to the control driver 400 .

[0479] In this case, the seventh viewing angle control signal generator 707 to the twelfth viewing angle control signal generator 712 may generate the seventh viewing angle control signal VCS7 to the twelfth viewing angle control signal VCS12 having a high level. The seventh viewing angle control signal VCS7 to the twelfth viewing angle control signal VCS12 may be transmitted to the seventh viewing angle switching unit 700g to the twelfth viewing angle switching unit 700l through the seventh viewing angle control line VCL7 to the twelfth viewing angle control line VCL12.

[0480] In this case, each of the seventh to twelfth viewing angle switching units 700g to 700l may transmit a first control signal CS1 having a high level to the first control signal line CL1 and may transmit a second control signal CS2 having a low level to the second control signal line CL2.

[0481] The sub-pixels P disposed in the seventh to twelfth emission areas EA7 to EA12 corresponding to the seventh to twelfth viewing angle switching units 700g to 700l may be provided with a first viewing angle control transistor Tvc1 connected to the first control signal line CL1 and a second viewing angle control transistor Tvc2 connected to the second control signal line CL2. In this case, Figure 2 As shown, the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 may be P-type transistors.

[0482] Therefore, in the subpixels P provided in the seventh to twelfth emission areas EA7 to EA12, only the second viewing angle control transistor Tvc2 may be turned on by the second control signal CS2 having a low level, and the first viewing angle control transistor Tvc1 may be turned off by the first control signal CS1 having a high level.

[0483] Therefore, in the seventh to twelfth light-emitting areas EA7 to EA12, as shown in FIG. Fig. 7AAs shown, a second image having a narrow viewing angle in the left-right direction, such as a general image, can be displayed by the second light emitting unit LU2. Therefore, only the passenger can see the general image.

[0484] In other words, when the vehicle is being operated, the general image IM2 that disturbs the driver may have a second viewing angle, such as a narrow viewing angle, so that it can only be seen by the passenger.

[0485] Therefore, the mode of the seventh to twelfth light emitting areas EA7 to EA12 may be the privacy mode (PM).

[0486] Next, if the vehicle is stopped or not operated in the parking mode, an operation stop signal may be transmitted from the external system 600 to the control driver 400 .

[0487] In this case, if the entire screen of the light-emitting display panel 100 is converted into a screen for viewing the general image IM2 by a user's selection or by an automatic function of the control driver 400, the first to twelfth viewing angle control signal generators 701 to 712 may generate first to twelfth viewing angle control signals VCS1 to VCS12 having a low level. The first to twelfth viewing angle control signals VCS1 to VCS12 may be transmitted to the first to twelfth viewing angle switching units 700a to 700l through the first to twelfth viewing angle control lines VCL1 to VCL12.

[0488] In this case, each of the first to twelfth viewing angle switching units 700a to 700l may transmit a first control signal CS1 having a low level to the first control signal line CL1 and may transmit a second control signal CS2 having a high level to the second control signal line CL2.

[0489] Therefore, in the subpixels P provided in the first to twelfth emission areas EA1 to EA12, only the first viewing angle control transistor Tvc1 can be turned on by the first control signal CS1 having a low level, and the second viewing angle control transistor Tvc2 can be turned off by the second control signal CS2 having a high level.

[0490] Therefore, in the first to twelfth light emitting areas EA1 to EA12, as shown in FIG. Figure 7B As shown, the second image IM2 having a wide viewing angle in the left-right direction, such as a general image, can be displayed by the first light emitting unit LU1. Therefore, both the driver and the passenger can see the general image.

[0491] In other words, when the vehicle is operated, the general image IM2 may disturb the driver. However, when the vehicle is not operated or stopped in the parking mode, there is almost no chance of an accident due to the general image IM2. Figure 7B As shown, a general image IM2 having a first viewing angle (eg, a wide viewing angle) may be displayed through the entire light-emitting display panel 100 .

[0492] Therefore, the mode of the first to twelfth light emitting areas EA1 to EA12 may be the sharing mode (SM).

[0493] To provide additional description, in the light emitting display device according to the present disclosure, each of the light emitting areas EA1 to EA12 may output an image having a wide viewing angle, or may output an image having a narrow viewing angle.

[0494] Furthermore, in the light emitting display device according to the present disclosure, the same type of image (eg, general image IM2 ) may have a narrow viewing angle or a wide viewing angle depending on a driving mode of a vehicle or the like.

[0495] Next, when the driver operates the vehicle, if the driver or the passenger selects the third image IM3 (eg, a vehicle operation information auxiliary image such as navigation), a vehicle operation information auxiliary signal may be transmitted from the external system 600 to the control driver 400 .

[0496] If the vehicle operation information auxiliary signal is transmitted from the external system 600 to the control driver 400 and the vehicle operation information auxiliary image IM3 is set to be displayed in the seventh to ninth light emitting areas EA7 to EA9, as shown in FIG. Figure 7C As shown, the seventh perspective control signal generator 707 to the ninth perspective control signal generator 709 can transmit the seventh perspective control signal VCS7 to the ninth perspective control signal VCS9 with a low level to the seventh perspective switching unit 700g to the ninth perspective switching unit 700i through the seventh perspective control line VCL7 to the ninth perspective control line VCL9.

[0497] In this case, each of the seventh to ninth viewing angle switching units 700g to 700i may transmit the first control signal CS1 having a low level to the first control signal line CL1 and may transmit the second control signal CS2 having a high level to the second control signal line CL2.

[0498] Therefore, in the subpixels P set in the seventh to ninth emission areas EA7 to EA9, only the first viewing angle control transistor Tvc1 can be turned on by the first control signal CS1 with a low level, and the second viewing angle control transistor Tvc2 can be turned off by the second control signal CS2 with a high level.

[0499] Therefore, in the seventh to ninth light-emitting areas EA7 to EA9, as shown in FIG. Figure 7C As shown, the third image IM3 with a wide viewing angle in the left-right direction, such as a vehicle operation information auxiliary image, can be displayed by the first light emitting unit LU1. Therefore, both the driver and the passenger can see the vehicle operation information auxiliary image.

[0500] Therefore, the mode of the seventh to ninth light emitting areas EA7 to EA9 may be the sharing mode (SM).

[0501] In other words, the vehicle operation information auxiliary image IM3 is an image that is beneficial to the driver and passengers when the vehicle is operated, and therefore, the vehicle operation information auxiliary image IM3 may have a first viewing angle, such as a wide viewing angle, so that both the driver and passengers can see it.

[0502] In addition, if the vehicle operation information auxiliary signal is transmitted from the external system 600 to the control driver 400 and the vehicle operation information auxiliary image IM3 is set to be displayed in the seventh light emitting area EA7 and the tenth light emitting area EA10, as shown in FIG. Fig.7D As shown, the seventh viewing angle control signal generator 707 and the tenth viewing angle control signal generator may transmit the seventh viewing angle control signal VCS7 and the tenth viewing angle control signal VCS10 having a low level to the seventh viewing angle switching unit 700g and the tenth viewing angle switching unit 700j.

[0503] In this case, each of the seventh and tenth viewing angle switching units 700g and 700j may transmit the first control signal CS1 having a low level to the first control signal line CL1 and may transmit the second control signal CS2 having a high level to the second control signal line CL2.

[0504] Therefore, in the subpixels P disposed in the seventh and tenth emission areas EA7 and EA10, only the first viewing angle control transistor Tvc1 can be turned on by the first control signal CS1 having a low level, and the second viewing angle control transistor Tvc2 can be turned off by the second control signal CS2 having a high level.

[0505] Therefore, in the seventh light emitting area EA7 and the tenth light emitting area EA10, as shown in FIG. Fig.7D As shown, the third image IM3 with a wide viewing angle in the left-right direction, such as a vehicle operation information auxiliary image, can be displayed by the first light emitting unit LU1. Therefore, both the driver and the passenger can see the vehicle operation information auxiliary image.

[0506] Therefore, the mode of the seventh light emitting area EA7 and the tenth light emitting area EA10 may be the shared mode (SM).

[0507] In other words, the vehicle operation information auxiliary image IM3 is an image that is beneficial to the driver and passengers when the vehicle is operated, and therefore, the vehicle operation information auxiliary image IM3 may have a first viewing angle, such as a wide viewing angle, so that both the driver and passengers can see it.

[0508] In particular, in the light emitting display device according to the present disclosure, as Figure 7C and Fig.7D As shown, the position where the image having the first viewing angle is output and the position where the image having the second viewing angle is output may be changed not only along the first direction X but also along the second direction Y.

[0509] That is, according to the light-emitting display device according to the present disclosure, the position where the image with the first viewing angle is output and the position where the image with the second viewing angle is output can be freely changed. Therefore, the driver or passenger can freely change the position where the image with the first viewing angle is output and the position where the image with the second viewing angle is output.

[0510] For example, the driver or passenger can use the external system 60 to Figure 7C The area shown (for example, the seventh light-emitting area EA7 to the ninth light-emitting area EA9) or Fig.7D The illustrated areas (eg, the seventh light emitting area EA7 and the tenth light emitting area EA10 ) are set as positions where the vehicle operation information auxiliary image IM3 such as navigation is output.

[0511] However, the external system 600 or the control driver 400 may fix the position of outputting the image affecting safe driving (such as the vehicle operation information image IM1 ) to a specific area (eg, the first to sixth light emitting areas EA1 to EA6 ).

[0512] Finally, when the vehicle is operated by the driver or the vehicle is not operated or stopped in the parking mode, if the emergency information image IM4 is received, an emergency information signal may be transmitted from the external system 600 to the control driver 400 .

[0513] For example, when receiving an emergency information signal, the eighth viewing angle control signal generator 708 may generate an eighth viewing angle control signal VCS8 having a low level. The eighth viewing angle control signal VCS8 may be transmitted to the eighth viewing angle switching unit 700h through the eighth viewing angle control line VCL8.

[0514] In this case, the eighth viewing angle switching unit 700h may transmit the first control signal CS1 having a low level to the first control signal line CL1, and may transmit the second control signal CS2 having a high level to the second control signal line CL2.

[0515] Therefore, in the subpixel P disposed in the eighth emission area EA8, only the first viewing angle control transistor Tvc1 may be turned on by the first control signal CS1 having a low level, and the second viewing angle control transistor Tvc2 may be turned off by the second control signal CS2 having a high level.

[0516] Therefore, in the eighth light emitting area EA8, if Fig. 7E As shown, a fourth image IM4 having a wide viewing angle in the left-right direction, such as an emergency information image, may be displayed by the first light emitting unit LU1.

[0517] Therefore, the mode of the eighth light emitting area EA8 may be the sharing mode (SM).

[0518] In other words, when the vehicle is operated, the emergency information image IM4 is an image that not only the driver but also the passenger needs to see, and therefore, the emergency information image IM4 may have a first viewing angle, such as a wide viewing angle, so that it can be seen by both the driver and the passenger.

[0519] In this case, the emergency information image IM4 can be displayed by displaying any one of the light emitting areas of the general image IM2 having the second viewing angle (narrow viewing angle), such as Fig. 7E shown.

[0520] However, if Fig. 7A and Figure 7F As shown, the emergency information image IM4 can be displayed by any one of the light emitting areas of the vehicle operation information image IM1 having the first viewing angle (wide viewing angle).

[0521] That is, in the light-emitting display device according to the present disclosure, each of the light-emitting areas EA1 to EA12 can be driven independently, and thus, each of the light-emitting areas EA1 to EA12 can independently display an image with a first viewing angle (wide viewing angle) or an image with a second viewing angle (narrow viewing angle).

[0522] Fig.23 and Fig.24 are other exemplary diagrams showing the structure of a viewing angle switching unit applied to a light-emitting display device according to the present disclosure, and Fig.25 is another exemplary diagram illustrating a structure of a viewing angle control unit applied to a light-emitting display device according to the present disclosure.

[0523] in this case, Fig.23 and Fig.24 The function of the perspective switching unit shown is the same or similar to the function of the perspective switching unit described above. Fig.25 The functions and references of the viewing angle control unit VCU shown Figure 2Therefore, in the following description, the functions of the viewing angle control unit VCU described in the reference are omitted or briefly described. Figures 1 to 22 The details described are the same or similar details.

[0524] first, Fig.23 The illustrated viewing angle switching unit 700 includes a first switching unit 710 and a second switching unit 720. The first switching unit 710 includes a first transistor unit TU1 and a first resistance unit RU1, and the second switching unit 720 includes a second transistor unit TU2 and a second resistance unit RU2.

[0525] The first switching unit 710 includes a 1a-th control transistor T1a and a 1b-th control transistor T1b. The 1a-th control transistor T1a and the 1b-th control transistor T1b may be formed of P-type transistors.

[0526] A gate of the 1a-th control transistor T1a is connected to an X-coordinate viewing angle control line VCLX to which an X-coordinate viewing angle control signal VCSX is provided, a first terminal of the 1a-th control transistor T1a is connected to a high voltage line HL, and a second terminal of the 1a-th control transistor T1a is connected to a first terminal of the 1b-th control transistor T1b.

[0527] A gate of the 1bth control transistor T1b is connected to the Y-coordinate viewing angle control line VCLY to which the Y-coordinate viewing angle control signal VCSY is provided, a first terminal of the 1bth control transistor T1b is connected to the second terminal of the 1ath control transistor T1a, and a second terminal of the 1bth control transistor T1b is connected to the first resistance unit RU1.

[0528] The second switching unit 720 includes a 2a-th control transistor T2a and a 2b-th control transistor T2b. The 2a-th control transistor T2a and the 2b-th control transistor T2b may be formed of P-type transistors.

[0531] In this case, if at least one of the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY has a high level, the first switching unit 710 outputs the low voltage VGL, and the second switching unit 720 outputs the high voltage VGH.

[0532] The low voltage VGL output from the first switching unit 710 is supplied to the first viewing angle control transistor Tvc1 through the first control signal line CL1, and the high voltage VGH output from the second switching unit 720 is supplied to the second viewing angle control transistor Tvc2 through the second control signal line CL2.

[0533] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions may be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1.

[0534] However, if the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY have a low level, the first switching unit 710 outputs the high voltage VGH, and the second switching unit 720 outputs the low voltage VGL.

[0535] Therefore, in the first light emitting area EA1, an image having a narrow viewing angle in the left and right directions may be output through the second light emitting unit LU2 connected to the second viewing angle control transistor Tvc2.

[0536] That is, to provide Fig.23 The viewing angle switching unit 700 shown in FIG. 1 is configured to output an image having a wide viewing angle (or a narrow viewing angle) by using viewing angle control signals VCSX and VCSY different from those provided to the image. Fig.19 The viewing angle switching unit 700 is shown to output viewing angle control signals VCSX and VCSY for an image having a wide viewing angle (or a narrow viewing angle).

[0537] However, referring to Figures 1 to 22 The described functionality can also be accomplished by Fig.23 The perspective switching unit 700 shown in FIG.

[0538] Next, Fig.24 The illustrated viewing angle switching unit 700 includes a first switching unit 710 and a second switching unit 720. The first switching unit 710 includes a first transistor unit TU1 and a first resistance unit RU1, and the second switching unit 720 includes a second transistor unit TU2 and a second resistance unit RU2.

[0539] The first switching unit 710 includes a 1a-th control transistor T1a and a 1b-th control transistor T1b. The 1a-th control transistor T1a and the 1b-th control transistor T1b may be formed of P-type transistors.

[0540] A gate of the 1a-th control transistor T1a is connected to an X-coordinate viewing angle control line VCLX to which an X-coordinate viewing angle control signal VCSX is provided, a first terminal of the 1a-th control transistor T1a is connected to a low voltage line LL, and a second terminal of the 1a-th control transistor T1a is connected to the first resistance unit RU1.

[0541] A gate of the 1bth control transistor T1b is connected to the Y-coordinate viewing angle control line VCLY provided with the Y-coordinate viewing angle control signal VCSY, a first terminal of the 1bth control transistor T1b is connected to the low voltage line LL, and a second terminal of the 1bth control transistor T1b is connected to the first resistance unit RU1.

[0542] The second switching unit 720 includes a 2a-th control transistor T2a and a 2b-th control transistor T2b. The 2a-th control transistor T2a and the 2b-th control transistor T2b may be formed of N-type transistors.

[0543] A gate of the 2a-th control transistor T2a is connected to an X-coordinate viewing angle control line VCLX to which an X-coordinate viewing angle control signal VCSX is provided, a first terminal of the 2a-th control transistor T2a is connected to a low voltage line LL, and a second terminal of the 2a-th control transistor T2a is connected to a first terminal of the 2b-th control transistor T2b.

[0544] A gate of the 2bth control transistor T2b is connected to the Y-coordinate viewing angle control line VCLY to which the Y-coordinate viewing angle control signal VCSY is provided, a first terminal of the 2bth control transistor T2b is connected to the second terminal of the 2ath control transistor T2a, and a second terminal of the 2bth control transistor T2b is connected to the second resistance unit RU2.

[0545] In this case, if at least one of the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY has a low level, the first switching unit 710 outputs the low voltage VGL, and the second switching unit 720 outputs the high voltage VGH.

[0546] The low voltage VGL output from the first switching unit 710 is supplied to the first viewing angle control transistor Tvc1 through the first control signal line CL1, and the high voltage VGH output from the second switching unit 720 is supplied to the second viewing angle control transistor Tvc2 through the second control signal line CL2.

[0547] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions may be output through the first light emitting unit LU1 connected to the first viewing angle control transistor Tvc1.

[0548] However, if the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY have a high level, the first switching unit 710 outputs the high voltage VGH, and the second switching unit 720 outputs the low voltage VGL.

[0549] Therefore, in the first light emitting area EA1, an image having a narrow viewing angle in the left and right directions may be output through the second light emitting unit LU2 connected to the second viewing angle control transistor Tvc2.

[0550] That is, to provide Fig.24 The viewing angle switching unit 700 shown in FIG. 1 is used to output an image having a wide viewing angle (or a narrow viewing angle) and the viewing angle control signals VCSX and VCSY provided to the image. Fig.19 The viewing angle switching unit 700 is shown to output an image having a wide viewing angle (or a narrow viewing angle) with the same viewing angle control signals VCSX and VCSY.

[0551] Therefore, refer to Figures 1 to 22 The functionality described can also be represented by Fig.24 The perspective switching unit 700 is shown to execute.

[0552] Finally, in Fig.25 In the figure, it is shown that the Figure 2 The structure of the view control unit VCU described is different from the structure of the view control unit VCU.

[0553] For example, in reference Figures 1 to 22 In the described light emitting display device, the viewing angle control signals VCSX and VCSY are provided to the viewing angle switching unit 700 provided in the non-display area NDA. In this case, one of the first viewing angle control transistor Tvc1 and the second viewing angle control transistor Tvc2 of the viewing angle control unit VCU is turned on by the first control signal CS1 and the second control signal CS2 provided from the viewing angle switching unit 700, and thus, an image with a wide viewing angle or an image with a narrow viewing angle can be output in the light emitting area EA.

[0554] However, in the Fig.25 In the light-emitting display device of the viewing angle control unit VCU shown, the viewing angle control signals VCSX and VCSY may be directly provided to the viewing angle control unit VCU, so that an image with a wide viewing angle or an image with a narrow viewing angle may be output in the light-emitting area EA.

[0555] to this end, Fig.25 The viewing angle control unit VCU shown includes a first viewing angle control transistor unit CT1 and a second viewing angle control transistor unit CT2.

[0556] The first viewing angle control transistor unit CT1 includes a 1a-th viewing angle transistor TC1a and a 1b-th viewing angle transistor TC1b. The 1a-th viewing angle transistor TC1a and the 1b-th viewing angle transistor TC1b may be formed of P-type transistors.

[0557] A gate of the 1a-th viewing angle transistor TC1a is connected to an X-coordinate viewing angle control line VCLX to which an X-coordinate viewing angle control signal VCSX is provided, a first terminal of the 1a-th viewing angle transistor TC1a is connected to a second terminal of the second light emitting transistor Tsw4b, and a second terminal of the 1a-th viewing angle transistor TC1a is connected to a first terminal of the first light emitting device ED1.

[0558] The gate of the 1b-th viewing angle transistor TC1b is connected to the Y-coordinate viewing angle control line VCLY to which the Y-coordinate viewing angle control signal VCSY is provided, the first terminal of the 1b-th viewing angle transistor TC1b is connected to the second terminal of the second light-emitting transistor Tsw4b, and the second terminal of the 1b-th viewing angle transistor TC1b is connected to the first terminal of the first light-emitting device ED1.

[0559] The second viewing angle control transistor unit CT2 includes a 2a-th viewing angle transistor TC2a and a 2b-th viewing angle transistor TC2b. The 2a-th viewing angle transistor TC2a and the 2b-th viewing angle transistor TC2b may be formed of N-type transistors.

[0560] A gate of the 2a viewing angle transistor TC2a is connected to the X-coordinate viewing angle control line VCLX to which the X-coordinate viewing angle control signal VCSX is provided, a first terminal of the 2a viewing angle transistor TC2a is connected to the second terminal of the second light emitting transistor Tsw4b, and a second terminal of the 2a viewing angle transistor TC2a is connected to the first terminal of the 2b viewing angle transistor TC2b.

[0561] The gate of the 2b-th viewing angle transistor TC2b is connected to the Y-coordinate viewing angle control line VCLY to which the Y-coordinate viewing angle control signal VCSY is provided, the first terminal of the 2b-th viewing angle transistor TC2b is connected to the second terminal of the 2a-th viewing angle transistor TC2a, and the second terminal of the 2b-th viewing angle transistor TC2b is connected to the first terminal of the second light-emitting device ED2.

[0562] In this case, if at least one of the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY has a low level, the first viewing angle control transistor unit CT1 is turned on and may supply current to the first light emitting device ED1.

[0563] If at least one of the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY has a low level, the second viewing angle control transistor unit CT2 is turned off, and thus cannot supply current to the second light emitting device ED2.

[0564] Therefore, in the first light emitting area EA1, an image having a wide viewing angle in the left and right directions may be output through the first light emitting unit LU1 connected to the first viewing angle control transistor unit CT1.

[0565] However, if the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY have a high level, the second viewing angle control transistor unit CT2 is turned on and may supply current to the second light emitting device ED2.

[0566] If the X-coordinate viewing angle control signal VCSX and the Y-coordinate viewing angle control signal VCSY have a high level, the first viewing angle control transistor unit CT1 is turned off, and thus cannot supply current to the first light emitting device ED1.

[0567] Therefore, in the first light emitting area EA, an image having a narrow viewing angle in the left and right directions may be output through the second light emitting unit LU2 connected to the second viewing angle control transistor unit CT2.

[0568] That is, to provide Fig.25 The viewing angle control unit VCU shown in the figure outputs an image with a wide viewing angle (or a narrow viewing angle) and the viewing angle control signals VCSX and VCSY provided to the image. Fig.19 The viewing angle switching unit 700 is shown to output an image having a wide viewing angle (or a narrow viewing angle) with the same viewing angle control signals VCSX and VCSY.

[0569] Therefore, refer to Figures 1 to 22 The image with a narrow viewing angle or the image with a wide viewing angle described can also be represented by Fig.25 The output of the view control unit VCU is shown.

[0570] According to the present disclosure as described above, the mode of the light emitting area EA may be controlled by the viewing angle switching unit 700 provided in the non-display area NDA of the light emitting display panel, and in particular, the mode of the light emitting area EA may be independently controlled.

[0571] In addition, according to the present disclosure as described above, the mode of the light emitting area EA can be controlled by the viewing angle control signal VCS. In this case, the viewing angle control signal VCS can be provided to the viewing angle switching unit 700 set in the non-display area NDA, or can be directly transmitted to the viewing angle control unit VCU set in the pixel driving circuit PDC.
