[0053] Figure 1 This is a block diagram illustrating a display device according to an embodiment of the present invention. Figure 2 It is used to illustrate that it includes Figure 1 The circuit diagram of a conventional pixel in a display device.

[0054] Reference Figure 1 According to an embodiment of the present invention, the display device DD may include a display panel PNL, a data driving unit DDV, a gate driving unit GDV, a light-emitting driving unit EDV, and a control unit CON.

[0055] The display panel PNL may include at least one conventional pixel (CPX) and at least one viewing angle adjustment pixel (VPX). The display panel PNL can display images through the conventional pixel (CPX) and the viewing angle adjustment pixel (VPX).

[0056] In one embodiment, the conventional pixel CPX may be a pixel with an unadjusted viewing angle, and the viewing angle adjustment pixel VPX may be a pixel with an adjusted viewing angle. For example, the viewing angle adjustment pixel VPX may form a lens and / or a light-shielding component. Consequently, the viewing angle adjustment pixel VPX may not emit light with an angle greater than a predetermined viewing angle.

[0057] In one embodiment, the display device DD can be driven in a first mode (e.g., a normal mode) and a second mode (e.g., a viewing angle adjustment mode). During the first mode, both the normal pixel CPX and the viewing angle adjustment pixel VPX can emit light. Alternatively, during the second mode, the normal pixel CPX may not emit light, while the viewing angle adjustment pixel VPX emits light.

[0058] The data driving unit DDV can be electrically connected to the conventional pixel CPX and the viewing angle adjustment pixel VPX. The data driving unit DDV can generate a data voltage DATA based on the output image data ODAT and transmit the data voltage DATA based on the data control signal DCTRL. For example, the output image data ODAT can be RGB data related to the image displayed in the display panel PNL, and the data control signal DCTRL can include an output data enable signal, a horizontal start signal, and a load signal.

[0059] The gate driving unit GDV can be electrically connected to the conventional pixel CPX and the viewing angle adjustment pixel VPX. The gate driving unit GDV can generate a gate signal GS based on the gate control signal GCTRL. In addition, the gate driving unit GDV can output the gate signal GS sequentially. For example, the gate control signal GCTRL may include a vertical start signal, a clock signal, etc.

[0060] The light-emitting drive unit (EDV) can be electrically connected to the conventional pixel (CPX) and the viewing angle adjustment pixel (VPX). The EDV can generate a light-emitting drive signal (EM) based on the light-emitting control signal (ECTRL). Furthermore, the EDV can sequentially output the light-emitting drive signal (EM). For example, the light-emitting control signal (ECTRL) may include a vertical start signal, a clock signal, etc.

[0061] The control unit CON (e.g., a timing controller) can receive input image data IDAT and control signals CTRL from an external main processor (e.g., a GPU). For example, the input image data IDAT may be RGB data including red, green, and blue image data. The control signal CTRL may include a vertical synchronization signal, a horizontal synchronization signal, an input data enable signal, a master clock signal, etc. The control unit CON can generate the output image data ODAT, the data control signal DCTRL, the gate control signal GCTRL, and the light emission control signal ECTRL based on the input image data IDAT and the control signal CTRL.

The first terminal may be electrically connected to the data voltage DATA. The second terminal may be electrically connected to the first terminal of the first transistor T1.

[0066] The second transistor T2 can be turned on or off in response to the first gate signal GW. For example, when the second transistor T2 is a PMOS transistor, it can be turned off when the first gate signal GW has a positive voltage level and turned on when the first gate signal GW has a negative voltage level. During the period when the second transistor T2 is turned on, it can transmit the data voltage DATA.

[0067] The third transistor T3 may include a gate terminal, a first terminal, and a second terminal. The gate terminal may be electrically connected to the first gate signal GW. The first terminal may be electrically connected to the second terminal of the first transistor T1. The second terminal may be electrically connected to the gate terminal of the first transistor T1.

[0068] The third transistor T3 can be turned on or off in response to the first gate signal GW. For example, when the third transistor T3 is a PMOS transistor, it can be turned off when the first gate signal GW has a positive voltage level and turned on when the first gate signal GW has a negative voltage level. During the period when the third transistor T3 is turned on, it can cause the first transistor T1 to be diode-connected. Consequently, the third transistor T3 can compensate for the threshold voltage of the first transistor T1.

[0069] The fourth transistor T4 may include a gate terminal, a first terminal, and a second terminal. The gate terminal may be electrically connected to a second gate signal GI. The first terminal may be electrically connected to an initialization voltage VINT. The second terminal may be electrically connected to the gate terminal of the first transistor T1.

For example, when the fourth transistor T4 is a PMOS transistor, it can be turned off when the second gate signal GI has a positive voltage level and turned on when the second gate signal GI has a negative voltage level. During the period when the fourth transistor T4 is turned on, it can transmit the initialization voltage VINT. Subsequently, the fourth transistor T4 can initialize the gate terminal of the first transistor T1.

The first terminal may be electrically connected to the high power supply voltage ELVDD. The second terminal may be electrically connected to the first transistor T1.

[0072] The fifth transistor T5 can be turned on or off in response to the light-emitting drive signal EM. For example, when the fifth transistor T5 is a PMOS transistor, it can be turned off when the light-emitting drive signal EM has a positive voltage level and turned on when the light-emitting drive signal EM has a negative voltage level. During the period when the fifth transistor T5 is turned on, it can transmit the high power supply voltage ELVDD.

[0073] The sixth transistor T6 may include a gate terminal, a first terminal, and a second terminal. The gate terminal may be electrically connected to the light-emitting driving signal EM. The first terminal may be electrically connected to the first transistor T1. The second terminal may be electrically connected to the light-emitting element LED.

[0074] The sixth transistor T6 can be turned on or off in response to the light-emitting drive signal EM. For example, when the sixth transistor T6 is a PMOS transistor, it can be turned off when the light-emitting drive signal EM has a positive voltage level and turned on when the light-emitting drive signal EM has a negative voltage level. During the period when the sixth transistor T6 is turned on, it can transmit the drive current.

[0075] The seventh transistor T7 may include a gate terminal, a first terminal, and a second terminal. The gate terminal may be electrically connected to a third gate signal GB. The first terminal may be electrically connected to the anode initialization voltage AINT. The second terminal may be electrically connected to the light-emitting element LED.

[0076] The seventh transistor T7 can be turned on or off in response to the third gate signal GB. For example, when the seventh transistor T7 is a PMOS transistor, it can be turned off when the third gate signal GB has a positive voltage level and turned on when the third gate signal GB has a negative voltage level. During the period when the seventh transistor T7 is turned on, it can transmit the anode initialization voltage AINT.

[0077] The storage capacitor CST may include a first terminal and a second terminal. The first terminal may be electrically connected to the high power supply voltage ELVDD. The second terminal may be electrically connected to the gate terminal of the first transistor T1.

[0078] The light-emitting element (LED) may include a first terminal and a second terminal. The first terminal can be electrically connected to the first transistor T1 via the sixth transistor T6. The second terminal can be electrically connected to a low power supply voltage ELVSS. The LED can emit light based on the driving current.

[0079] The first to seventh transistors T1, T2, T3, T4, T5, T6, and T7 can be PMOS transistors, but the present invention is not limited thereto. For example, at least one of the first to seventh transistors T1, T2, T3, T4, T5, T6, and T7 can be an NMOS transistor.

[0080] In addition, the number of transistors, the number of capacitors, and the connection relationship between transistors and capacitors can be changed as needed.

[0081] In one embodiment, the view adjustment pixel VPX (refer to...) Figure 1 The viewing angle adjustment pixel (VPX) can have substantially the same circuit structure as the conventional pixel (CPX). In another embodiment, the viewing angle adjustment pixel (VPX) can have a different circuit structure than the conventional pixel (CPX).

[0082] Figure 3 It is used for explanation Figure 1 A plan view of the display device. Figure 4 It is used to illustrate that it includes Figure 3 A graph showing the brightness ratio of pixels that adjust for viewing angle in a display device.

[0083] Reference Figure 3 The display device DD may include the display panel PNL, which may have a display surface formed by a first direction D1, a second direction D2 opposite to the first direction D1, and a third direction D3 perpendicular to the first and second directions D1 and D2. Additionally, the display panel PNL may have a thickness in a fourth direction D4 perpendicular to the first to third directions D1, D2, and D3.

[0084] The display surface of the display panel PNL can be arranged with multiple conventional pixels and multiple viewing angle adjustment pixels.

[0085] For example, the conventional pixel CPX (reference) Figure 1 It can include the first to fifth regular pixels CPX1, CPX2, CPX3, CPX4, and CPX5.

[0086] In one embodiment, the first conventional pixel CPX1 may be located at the center of the display panel PNL.

The fifth conventional pixel CPX5 can be located at the periphery of the display panel PNL, and the fourth conventional pixel CPX4 can be located between the first conventional pixel CPX1 and the fifth conventional pixel CPX5.

[0088] For example, the view adjustment pixel VPX (reference) Figure 1 It can include the first to fifth viewpoint adjustment pixels VPX1, VPX2, VPX3, VPX4, and VPX5.

[0089] In one embodiment, the first viewing angle adjustment pixel VPX1 may be located at the center of the display panel PNL. The second viewing angle adjustment pixel VPX2 may be spaced apart from the first viewing angle adjustment pixel VPX1 in the first direction D1, and the third viewing angle adjustment pixel VPX3 may be spaced apart from the second viewing angle adjustment pixel VPX2 in the first direction D1. The fourth viewing angle adjustment pixel VPX4 may be spaced apart from the first viewing angle adjustment pixel VPX1 in the second direction D2, and the fifth viewing angle adjustment pixel VPX5 may be spaced apart from the fourth viewing angle adjustment pixel VPX4 in the second direction D2.

[0090] The third viewing angle adjustment pixel VPX3 can be located at the periphery of the display panel PNL, and the second viewing angle adjustment pixel VPX2 can be located between the first viewing angle adjustment pixel VPX1 and the third viewing angle adjustment pixel VPX3. The fifth viewing angle adjustment pixel VPX5 can be located at the periphery of the display panel PNL, and the fourth viewing angle adjustment pixel VPX4 can be located between the first viewing angle adjustment pixel VPX1 and the fifth viewing angle adjustment pixel VPX5.

[0091] In one embodiment, the first conventional pixel CPX1 may be adjacent to the first viewing angle adjustment pixel VPX1, the second conventional pixel CPX2 may be adjacent to the second viewing angle adjustment pixel VPX2, the third conventional pixel CPX3 may be adjacent to the third viewing angle adjustment pixel VPX3, the fourth conventional pixel CPX4 may be adjacent to the fourth viewing angle adjustment pixel VPX4, and the fifth conventional pixel CPX5 may be adjacent to the fifth viewing angle adjustment pixel VPX5.

[0092] Reference Figure 4In one embodiment, the light emitted from the viewing angle adjustment pixel may include front light and side light. The front light may be light emitted in a vertical direction (e.g., the fourth direction D4) relative to the display panel PNL. The side light may be light emitted in an acute angle α relative to the vertical direction. The acute angle α may be a predetermined angle between 0 degrees and 90 degrees, for example, approximately 35 degrees.

[0093] In one embodiment, the brightness ratio of a pixel can be adjusted according to each viewing angle. The brightness ratio can be defined as the ratio of the brightness of the side light to the brightness of the front light.

[0094] In one embodiment, the light emitted from the first viewing angle adjusted pixel VPX1 may include a first front light L0_VPX1 and a first side light La_VPX1. The first front light L0_VPX1 may be light emitted in a vertical direction (e.g., the fourth direction D4) relative to the display panel PNL. The first side light La_VPX1 may be light emitted in an acute angle α direction relative to the vertical direction.

[0095] In one embodiment, the first brightness ratio R1 of the first viewing angle adjustment pixel VPX1 can be defined as the ratio of the brightness of the first side light La_VPX1 to the brightness of the first front light L0_VPX1. In other words, it can be R1 = La_VPX1 / L0_VPX1.

[0096] In one embodiment, the light emitted by pixel VPX2 adjusted from the second viewing angle may include a second front light L0_VPX2 and a second side light La_VPX2. The second front light L0_VPX2 may be light emitted in a vertical direction (e.g., the fourth direction D4) relative to the display panel PNL. The second side light La_VPX2 may be light emitted in an acute angle α direction relative to the vertical direction.

[0097] In one embodiment, the second brightness ratio R2 of the second viewing angle adjustment pixel VPX2 can be defined as the ratio of the brightness of the second side light La_VPX2 to the brightness of the second front light L0_VPX2. In other words, it can be R2 = La_VPX2 / L0_VPX2.

[0098] In one embodiment, the light emitted from the third-viewpoint adjustable pixel VPX3 may include a third front light L0_VPX3 and a third side light La_VPX3. The third front light L0_VPX3 may be light emitted in a vertical direction (e.g., the fourth direction D4) relative to the display panel PNL. The third side light La_VPX3 may be light emitted in an acute-angle direction relative to the vertical direction.

[0099] In one embodiment, the third luminance ratio R3 of the third viewing angle adjustment pixel VPX3 can be defined as the ratio of the luminance of the third side light La_VPX3 to the luminance of the third front light L0_VPX3. In other words, it can be R3 = La_VPX3 / L0_VPX3.

[0100] In one embodiment, the luminance ratios defined by the viewing angle adjustment pixels can be different from each other. For example, the luminance ratio of the viewing angle adjustment pixels located at the periphery of the display panel PNL can be smaller than the luminance ratio of the viewing angle adjustment pixels located at the center of the display panel PNL. In other words, as... Figure 4 As shown, the brightness ratio can decrease as it moves toward the periphery of the display panel PNL.

[0101] In one embodiment, the third luminance ratio R3 may be less than the second luminance ratio R2, and the second luminance ratio R2 may be less than the first luminance ratio R1. For example, the luminance of the third side light La_VPX3 may be less than the luminance of the second side light La_VPX2, and the luminance of the second side light La_VPX2 may be less than the luminance of the first side light La_VPX1.

[0102] Figure 5 It is used for explanation Figure 3 A diagram showing the display device driven in normal mode. Figure 6 It is used for explanation Figure 3 A diagram showing a display device driven in viewing angle adjustment mode. Figure 7 It is used to explain in Figure 3 A graph showing the intensity of light measured from the front during operation of the display device in either normal or viewing angle adjustment mode.

[0103] Reference Figure 5 For example, the display device DD can be installed in a car. While the car is parked, the display device DD can operate in the normal mode. At this time, the driver and the front passenger can view the images.

[0104] Reference Figure 6 While the car is in motion, the display device DD can be driven in the viewing angle adjustment mode. In this mode, the driver cannot view the image, but the passenger in the front passenger seat can.

[0105] Reference Figure 7 As described above, in the display device DD (refer to) of the present invention Figure 1 In the display panel PNL (reference), the brightness ratio of the viewing angle adjustment pixel can be adjusted according to the viewing angle adjustment pixel. Figure 1The brightness of the central portion of the display panel decreases as it moves towards the periphery. In contrast, in conventional display devices, the brightness ratio of all viewing angle adjustment pixels arranged on the display panel may be the same for each other.

[0106] During the period when the display device DD is driven in the viewing angle adjustment mode, the intensity of light measured from the front of the display device DD can be greater than the intensity of light measured from the front of a conventional display device. In other words, during the period when the display device DD is driven in the viewing angle adjustment mode, the brightness distribution according to the viewing angle of the display device DD can be improved. Consequently, the amount of brightness variation perceived by a user (e.g., the passenger) viewing the display device DD from the front can be reduced, which can reduce the user's dizziness or eye fatigue.

[0142] In one embodiment, the thicknesses of the first to third light-shielding components BM1, BM2, and BM3 may be the same. In another embodiment, the thicknesses of the first to third light-shielding components BM1, BM2, and BM3 may be different from each other. For example, the thickness of the first light-shielding component BM1 may be less than the thickness of the second light-shielding component BM2, and the thickness of the second light-shielding component BM2 may be less than the thickness of the third light-shielding component BM3.

[0143] The first viewing angle adjustment pixel VPX1 may include a first lens LS1 having a relatively large first radius of curvature and a first light-shielding member BM1 having a relatively small first width W1.

Figure 9a The described display device DD1 is substantially the same.

[0192] The first protective layer PVX1 can cover the first to third light-shielding components BM1, BM2, and BM3.

[0193] The second upper light-shielding component UBM2 can be disposed on the first protective layer PVX1 and can overlap with the second light-shielding component BM2. The second upper light-shielding component UBM2 may include a light-shielding material that can block a portion of the light emitted from the second light-emitting layer EL2.

[0194] The third-1 upper light-shielding component UBM3-1 can be disposed on the first protective layer PVX1 and can overlap with the third light-shielding component BM3. The third-1 upper light-shielding component UBM3-1 can include a light-shielding material that can block a portion of the light emitted from the third light-emitting layer EL3.

[0195] The second protective layer PVX2 can cover the second upper light-shielding component UBM2 and the third-first upper light-shielding component UBM3-1.

[0196] The third-2 upper light-shielding component UBM3-2 can be disposed on the second protective layer PVX2 and can overlap with the third-1 upper light-shielding component UBM3-1. The third-2 upper light-shielding component UBM3-2 can include a light-shielding material that can block a portion of the light emitted from the third light-emitting layer EL3.

[0197] The first light-shielding component BM1 may have a first width W1.

[0198] The second light-shielding component BM2 and the second upper light-shielding component UBM2 may have the first width W1.

[0199] The third light-shielding component BM3, the third-1 upper light-shielding component UBM3-1, and the third-2 upper light-shielding component UBM3-2 may have the first width W1.

[0200] like Figure 13a As shown, the number of light-shielding components vertically stacked on the first light-emitting layer EL1 can be less than the number of light-shielding components vertically stacked on the second light-emitting layer EL2. Furthermore, the number of light-shielding components vertically stacked on the second light-emitting layer EL2 can be less than the number of light-shielding components vertically stacked on the third light-emitting layer EL3.

[0201] For example, the number of light-shielding components vertically stacked on the first light-emitting layer EL1 can be one, the number of light-shielding components vertically stacked on the second light-emitting layer EL2 can be two, and the number of light-shielding components vertically stacked on the third light-emitting layer EL3 can be three.

[0202] In other words, no light-shielding component may be provided on the first light-shielding component BM1, no light-shielding component may be provided on the second upper light-shielding component UBM2, and no light-shielding component may be provided on the third-second upper light-shielding component UBM3-2.

[0203] The first viewing angle adjustment pixel VPX1 may include a relatively small number of vertically stacked light-shielding components. Consequently, the first brightness ratio R1 of the first viewing angle adjustment pixel VPX1 (refer to...) Figure 4 It can be relatively large.

[0204] The third-view adjustment pixel VPX3 may include a relatively large number of vertically stacked light-blocking components. Consequently, the third luminance ratio R3 of the third-view adjustment pixel VPX3 (refer to...) Figure 4 It can be relatively small.

[0205] Reference Figure 13b According to yet another embodiment of the present invention, the display device DD4' may include lenses. For example, the display device DD4' may include a first lens LS1', a second lens LS2', and a third lens LS3'. However, the display device DD4' may be other than the first lens LS1', the second lens LS2', and the third lens LS3' described above (see also...). Figure 13a They are essentially the same.

[0206] The first lens LS1' may be disposed on the planarization layer OC. In one embodiment, the first lens LS1' may overlap with the first light-emitting layer EL1. The first lens LS1' may redirect the path of light emitted from the first light-emitting layer EL1 toward the vertical direction (e.g., the fourth direction D4). For example, the first lens LS1' may have a first radius of curvature.

[0207] The second lens LS2' may be disposed on the planarization layer OC. In one embodiment, the second lens LS2' may overlap with the second light-emitting layer EL2. The second lens LS2' may redirect the path of light emitted from the second light-emitting layer EL2 toward the vertical direction (e.g., the fourth direction D4). For example, the second lens LS2' may have a second radius of curvature.

[0208] The third lens LS3' can be disposed on the planarization layer OC. In one embodiment, the third lens LS3' can overlap with the third light-emitting layer EL3. The third lens LS3' can change the path of light emitted from the third light-emitting layer EL3 towards the vertical direction (e.g., the fourth direction D4). For example, the third lens LS3' can have a third radius of curvature.

[0209] In one embodiment, the third radius of curvature may be smaller than the second radius of curvature, and the second radius of curvature may be smaller than the first radius of curvature. In other words, the curvature of the third lens LS3' may be greater than the curvature of the second lens LS2', and the curvature of the second lens LS2' may be greater than the curvature of the first lens LS1'. Consequently, the focusing efficiency of the third lens LS3' may be greater than the focusing efficiency of the second lens LS2', and the focusing efficiency of the second lens LS2' may be greater than the focusing efficiency of the first lens LS1'.

[0210] In one embodiment, the heights of the first lens LS1', the second lens LS2', and the third lens LS3' may be substantially the same. Additionally, the width of the first lens LS1' may be greater than the width of the second lens LS2', and the width of the second lens LS2' may be greater than the width of the third lens LS3'.

[0216] The first viewing angle adjustment pixel VPX1 may include a relatively small number of vertically stacked light-shielding components, the width of which may be relatively small. Consequently, the first brightness ratio R1 of the first viewing angle adjustment pixel VPX1 (refer to...) Figure 4 It can be relatively large.

[0217] The third-view adjustment pixel VPX3 may include a relatively large number of vertically stacked light-shielding components, the width of which may be relatively large. Consequently, the third luminance ratio R3 of the third-view adjustment pixel VPX3 (refer to...) Figure 4 It can be relatively small.
