Description

[Technical Field]

[0001] The present specification relates to a display device, and more particularly to a display device capable of controlling a viewing angle. [Background technology]

[0002] As technology in modern society develops, display devices are used in a variety of ways to provide information to users. Display devices include electronic boards that simply transmit visual information in one direction, as well as various electronic devices that require more advanced technology to confirm user input and provide information corresponding to the confirmed input.

[0003] For example, a display device may be installed in a vehicle to provide various information to the driver and passengers of the vehicle. However, the display device of the vehicle must display content appropriately so as not to interfere with the operation of the vehicle. For example, the display device must limit the display of content that may distract the driver from driving while the vehicle is in operation. Summary of the Invention [Problem to be solved by the invention]

[0004] The problem to be solved by this specification is to provide a display device that can minimize the problem of a visible boundary between a first region that provides content at a wide viewing angle and a second region that provides content at a wide or narrow viewing angle.

[0005] The objects of the present invention are not limited to those mentioned above, and other objects not mentioned above will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0006] A display device according to an embodiment of the present specification may include a display panel partitioned into a first region including a plurality of first pixels and a second region adjacent to the first region in a direction opposite to the first direction and including a plurality of second pixels, and a brightness controller configured to control the brightness of the first region. Each of the plurality of first pixels may include a first light-emitting element disposed on the first optical region, a second light-emitting element disposed on the second optical region, a first optical member disposed on the first optical region and configured to emit light generated from the first light-emitting element at a first viewing angle, and a second optical member disposed on the second optical region and configured to emit light generated from the second light-emitting element at the first viewing angle. Each of the plurality of second pixels may include a third light-emitting element disposed on the third optical region, a fourth light-emitting element disposed on the fourth optical region, a third optical member disposed on the third optical region and configured to emit light generated from the third light-emitting element at the first viewing angle, and a fourth optical member disposed on the fourth optical region and configured to emit light generated from the fourth light-emitting element at a second viewing angle lower than the first viewing angle. The brightness controller may control the brightness of the second optical region included in each of the plurality of first pixels disposed on the first region.

[0007] Further details of the embodiments are included in the detailed description and drawings.

[0008] In this specification, the brightness of the display panel can be controlled so that in a first mode that provides content at a wide viewing angle depending on the driving mode, the brightness of the first region increases as the distance from the boundary between the first region and the second region increases.

[0009] The present specification provides a method for controlling the brightness of a region in a first region adjacent to the boundary between the first region and the second region to have a value that is substantially the same as or similar to the brightness of the second region, thereby improving the problem of the boundary between the first region and the second region being visible.

[0019] The area and thickness of each component shown in the drawings are shown for convenience of explanation, and the present specification is not necessarily limited to the area and thickness of the components shown.

[0020] The features of the various embodiments of this specification may be partially or wholly combined or combined with each other, and may be technically interlocked and operated in various ways, and each embodiment may be implemented independently of each other or in conjunction with each other.

[0021] In the following, the present specification will be described with reference to the drawings.

[0022] FIG. 1 is a diagram illustrating a display device according to an embodiment of the present specification.

[0023] 1, the display device 100 may be disposed in at least a portion of a vehicle dashboard. The vehicle dashboard may include a configuration disposed in front of the front seats (e.g., driver's seat, passenger seat) of the vehicle. For example, the vehicle dashboard may include an input configuration for operating various functions inside the vehicle (e.g., air conditioning, audio system, navigation system).

[0024] The display device 100 is disposed on the dashboard of a vehicle and can operate as an input unit for operating at least some of the vehicle's various functions. The display device 100 can provide various information related to the vehicle, such as vehicle operation information (e.g., the vehicle's current speed, the amount of remaining fuel, and the mileage), information on vehicle parts (e.g., the degree of damage to the vehicle's tires), etc.

[0025] The display device 100 may be disposed across the driver's seat and passenger seat, which are located in the front seats of a vehicle. Users of the display device 100 may include the driver of the vehicle and a passenger sitting in the passenger seat. Any of the driver and passengers of the vehicle may use the display device 100.

[0026] The display device 100 shown in Fig. 1 may be only partially illustrated. The display device 100 shown in Fig. 1 may be a display panel among various components included in the display device 100. To give a specific example, the display device 100 shown in Fig. 1 may be a display panel that includes at least a portion of a display area and a non-display area of ​​a display panel. Components of the display device 100 other than those shown in Fig. 1 may be implemented (or at least a portion of) inside a vehicle.

[0027] FIG. 2 is a functional block diagram of a display device according to an embodiment of the present specification.

[0028] The display device according to an embodiment of the present specification may be an electroluminescent display device, which may be an organic light emitting diode (OLED) display device, a quantum dot light emitting diode (QLD) display device, or an inorganic light emitting diode (ILD) display device.

[0029] 2, the display device 100 may include a display panel PN, a data driving circuit DD, a gate driving circuit GD, a timing controller TD, and a brightness controller LD. The display device 100 may further include a mode controller MS and a mode selection unit MD.

[0030] The display panel PN can generate an image to be provided to a user. For example, the display panel PN can generate and display an image to be provided to a user through a plurality of pixels PX, each of which has a pixel circuit arranged therein.

[0031] The pixels PX may include first and second pixels arranged in different regions of the display panel PN. The first and second pixels and their relative positions will be described in detail below with reference to FIGS. 8A to 11.

[0032] The data driving circuit DD, the gate driving circuit GD, and the timing controller TD may provide signals for operating each pixel PX through signal lines, for example, the signal lines for providing signals for operating each pixel PX may include a plurality of data lines DL and a plurality of gate lines GL.

[0033] The mode selection unit MD can provide signals for controlling the driving modes of each pixel PX through signal wirings. For example, the signal wirings for providing signals for controlling the driving modes of each pixel PX can include a plurality of selection signal wirings SSL.

[0034] The plurality of data lines DL may be arranged in a column direction and may include a plurality of lines connected to pixels PX arranged in one column direction, and the plurality of gate lines GL may be arranged in a row direction and may include a plurality of lines connected to pixels PX arranged in one row direction.

[0035] The plurality of selection signal lines SSL may include a plurality of lines arranged in the row direction and connected to the pixels PX arranged in one row direction.

[0036] The plurality of selection signal lines SSL may include first to fourth selection signal lines. Here, the first and second selection signal lines may be selection signal lines commonly connected to a first pixel included in the plurality of pixels PX, and the third and fourth selection signal lines may be selection signal lines commonly connected to a second pixel included in the plurality of pixels PX. A detailed description of the connection relationship of the first to fourth selection signal lines will be given later with reference to Figures 8a and 9a.

[0037] In some cases, the display device 100 may further include a power supply unit. In this case, signals for operating the pixels PX may be provided through power lines connecting the power supply unit to the display panel PN. According to an embodiment, the power supply unit may provide power to the data driving circuit DD and the gate driving circuit GD. The data driving circuit DD and the gate driving circuit GD may be driven based on the power provided by the power supply unit.

[0038] As an example, the data driving circuit DD can apply data signals to each pixel PX through a plurality of data lines DL, the gate driving circuit GD can apply gate signals to each pixel PX through a plurality of gate lines GL, and the power supply unit can supply a power supply voltage to each pixel PX through a power supply voltage supply line.

[0039] The brightness controller LD can receive digital input image data IDATA and a mode signal MODE input from the outside. Here, the mode signal MODE may be a signal input corresponding to a driving mode of the display device 100.

[0040] The luminance controller LD can generate corrected video data CDATA for controlling the luminance of the display panel PN depending on the drive mode of the display device 100 based on the mode signal MODE.

[0041] For example, in a first mode in which the entire area of ​​the display panel PN of the display device 100 is controlled to a wide viewing mode (Share mode), the brightness controller LD may generate the correction image data CDATA for controlling the brightness of at least a portion of the display panel PN, for example, a first area. As an example, in the first mode, the brightness controller LD may generate the correction image data CDATA for reducing the brightness of the first area.

[0042] The brightness controller LD may generate the corrected image data CDATA by scaling grayscale values ​​included in the input image data IDATA using a scale factor. For example, the brightness controller LD may generate the corrected image data CDATA by scaling grayscale values ​​corresponding to at least a portion of the display panel PN, for example, a first region. However, this is merely an example, and the method by which the brightness controller LD generates the corrected image data CDATA is not limited thereto.

[0043] As another example, in a second mode in which the display device 100 controls at least a portion of the display panel PN, for example, the first region, to a wide-view mode (Share mode) and controls another portion of the display panel PN, for example, the second region, to a narrow-view mode (Private mode), the brightness controller LD can generate corrected image data CDATA to control the brightness of the entire region of the display panel PN to correspond to the input image data IDATA.

[0044] In the second mode, the brightness of the entire area of ​​the display panel PN must correspond to the input image data IDATA, so the corrected image data CDATA may be substantially the same as the input image data IDATA. For example, in the second mode, the brightness controller LD may not correct the input image data IDATA and may output the input image data IDATA as the corrected image data CDATA.

[0045] The timing controller TD can control the data driving circuit DD and the gate driving circuit GD. For example, the timing controller TD can realign the corrected image data CDATA provided from the luminance controller LD to match the resolution of the display panel PN to generate image data RGB and supply it to the data driving circuit DD.

[0046] As described above, when the display device 100 is driven in the first mode, the brightness of an image displayed on at least a portion of the display panel PN, for example, the first region, may be controlled based on the corrected image data CDATA generated by scaling the grayscale values ​​of the input image data IDATA by the brightness controller LD. A detailed description of a configuration for controlling the brightness of the display panel PN based on the corrected image data CDATA will be given later with reference to FIGS. 12 to 18.

[0047] 2, for convenience of explanation, the brightness controller LD and the timing controller TD are described as being separate components, but the present invention is not limited thereto. For example, a part or the whole of the brightness controller LD may be integrated into the timing controller TD.

[0048] The data driving circuit DD can convert the video data RGB input from the timing controller TD based on the data control signal into an analog data signal (data voltage) and supply it to a plurality of data lines DL.

[0049] The gate driver GD can generate scan signals and light emission signals (or light emission control signals) based on the gate control signals. For example, the gate driver GD can include a scan driver and a light emission signal driver. The scan driver can generate scan signals in a row sequential manner to drive at least one scan line connected to each row of pixels and supply them to the scan lines. The light emission signal driver can generate light emission signals in a row sequential manner to drive at least one light emission signal line connected to each row of pixels and supply them to the light emission signal lines.

[0050] According to an embodiment, the gate driving circuit GD may be arranged on the display panel PN in a GIP (Gate-driver In Panel) manner. For example, the gate driving circuit GD may be divided into a plurality of parts and arranged on at least two sides of the display panel PN, respectively.

[0051] The mode controller MS can control the mode selection unit MD. For example, the mode controller MS can generate a mode selection signal MSS for controlling the mode selection unit MD based on a mode signal MODE input corresponding to a driving mode of the display device 100, and provide the generated signal to the mode selection unit MD. The mode selection unit MD can provide selection signals to a plurality of selection signal lines SSL in response to the mode selection signal MSS.

[0052] The display panel PN can include a display area and a non-display area surrounding the display area.

[0053] The display area of ​​the display panel PN may include a plurality of pixels PX arranged in row and column directions. For example, the plurality of pixels PX may be arranged in an area where a plurality of data lines DL and a plurality of gate lines GL intersect.

[0054] A pixel PX may include multiple sub-pixels that emit different colors. For example, a pixel PX may use three sub-pixels to implement blue, red, and green. However, the present invention is not limited thereto, and the pixel PX may include an additional sub-pixel to implement a specific color, for example, white, in some cases.

[0055] In the pixel PX, a region that realizes blue may be referred to as a blue sub-pixel, a region that realizes red may be referred to as a red sub-pixel, and a region that realizes green may be referred to as a green sub-pixel.

[0056] Each of the plurality of pixels PX can include a first type light emitting element and a second type light emitting element that emit light of the same color.

[0057] Each of the plurality of pixels PX may include at least one of a first type lens and a second type lens that refracts light from the first type light emitting element and the second type light emitting element in a specific direction. Meanwhile, the term "lens" used in this specification is used for convenience of explanation, and may also be defined as the term "optical element" instead of a lens.

[0058] For example, a first type of lens may be disposed in a lens region that provides light to a first range to form a first viewing angle, and a second type of lens may be disposed in a lens region that provides light to a second range to form a second viewing angle. The first range may be wider than the second range. Thus, the first type of lens and the second type of lens may limit the viewing angle of each of the plurality of pixels PX.

[0059] The first and second type lenses will be described in detail below with reference to FIGS.

[0060] The non-display area may be arranged along the periphery of the display area. Various components for driving pixel circuits arranged in the pixels PX may be arranged in the non-display area. For example, at least a portion of the gate drive circuit GD may be arranged in the non-display area. The non-display area may be referred to as a bezel area.

[0061] The display panel PN may be divided into a plurality of regions. In other words, the display panel PN may include a plurality of regions. For example, the display panel PN may include a first region in which a plurality of first pixels among the plurality of pixels PX are arranged and a second region in which a plurality of second pixels among the plurality of pixels PX are arranged. The plurality of first pixels arranged in the first region and the plurality of second pixels arranged in the second region may each include the same pixel circuit.

[0062] For example, each of a plurality of first pixels arranged in a first region of the display panel PN and a plurality of second pixels arranged in a second region may include a driving circuit, a selection circuit, a first type light-emitting element and a second type light-emitting element that emit the same color.

[0063] Here, the driving circuit may be a circuit for providing driving currents to the first type light emitting element and the second type light emitting element based on signals provided from the data driving circuit DD and the gate driving circuit GD.

[0064] The selection circuit may be a circuit for controlling the generation of at least one of a first driving current passing through a first type of light emitting element and a second driving current passing through a second type of light emitting element based on a selection signal provided from the mode selection unit MD. In other words, by controlling the selection circuit, a current path for the first driving current is formed to cause the first type of light emitting element to emit light, or a current path for the second driving current is formed to cause the second type of light emitting element to emit light. However, without being limited thereto, the selection circuit may also be defined as being included in the driving circuit.

[0065] Meanwhile, for ease of explanation, in the following, when a current path of a first driving current is formed and a first type of light-emitting element emits light, the pixel PX is defined as being driven in a first state, and when a current path of a second driving current is formed and a second type of light-emitting element emits light, the pixel PX is defined as being driven in a second state.

[0066] The selection circuit may be controlled based on the selection signal provided by the mode selection unit MD so that both the first driving current passing through the first type light emitting element and the second driving current passing through the second type light emitting element are formed. In other words, by controlling the selection circuit in this manner, a current path for the first driving current and a current path for the second driving current are formed, respectively, so that both the first type light emitting element and the second type light emitting element can emit light.

[0067] Meanwhile, for convenience of explanation, in the following, it is defined that the pixel PX is driven in the third state when the current path of the first driving current and the current path of the second driving current are respectively formed and the first type light-emitting element and the second type light-emitting element all emit light.

[0068] Each of the plurality of first pixels arranged in the first region of the display panel PN may include two first-type lenses, e.g., a first lens and a second lens, that refract light from the first-type light-emitting element and the second-type light-emitting element, respectively, in a specific direction. For example, light generated from the first-type light-emitting element included in each of the plurality of first pixels arranged in the first region of the display panel PN may be refracted in a specific direction through the first lens embodied in the first-type lens, and light generated from the second-type light-emitting element may be refracted in a specific direction through the second lens embodied in the first-type lens.

[0069] Each of the plurality of second pixels arranged in the second region of the display panel PN may include a first type lens, e.g., a third lens, that refracts light from the first type light-emitting element in a specific direction, and a second type lens, e.g., a fourth lens, that refracts light from the second type light-emitting element in a specific direction. For example, light generated from the first type light-emitting element included in each of the plurality of second pixels arranged in the second region of the display panel PN may be refracted in a specific direction through the third lens embodied in the first type lens, and light generated from the second type light-emitting element included in each of the plurality of second pixels arranged in the second region of the display panel PN may be refracted in a specific direction through the fourth lens embodied in the second type lens.

[0070] A detailed description of the multiple regions included in the display panel PN, for example, the first and second regions, and the first and second pixels arranged in the first and second regions, will be given later with reference to Figures 8a to 11.

[0071] According to the embodiment, the regions of the display panel PN are disposed across the driver's seat and passenger seat, respectively, located in the front seats of the vehicle as described with reference to FIG. 1, and can provide various information to the driver and passengers of the vehicle. For example, the first region of the display panel PN is provided on the driver's seat side and can provide information such as driving speed and RPM, engine temperature, and fuel level. The second region of the display panel PN is provided on the passenger seat side and can provide entertainment functions and seat information for the passenger in the passenger seat. Meanwhile, the first region of the display panel PN may further include a center fascia region disposed between the driver's seat and passenger seat. However, this region division is for convenience of explanation, and the first and second regions of the display panel PN may be defined in various ways depending on the design.

[0072] Meanwhile, when the display panel PN is used in the vehicle described with reference to Fig. 1, it is necessary to restrict the field of view of at least some of the regions included in the display panel PN in response to a user request. For example, in the case of an image displayed in the second region that provides entertainment functions, seat information, etc. for a passenger in the front passenger seat, this may interfere with the driver's driving of the vehicle, so it may be necessary to restrict the field of view of the image displayed in the second region in response to a user request.

[0073] More specifically, referring to FIG. 2, the display device 100 can control the field of view of at least some of a plurality of regions included in the display panel PN by using a mode controller MS and a mode selection unit MD.

[0074] The mode controller MS may generate a mode selection signal MSS to the mode selection unit MD based on the mode signal MODE, which allows the display panel PN to be controlled to a first mode or a second mode depending on the driving mode of the display device 100. Here, the first mode may correspond to a mode in which a plurality of regions of the display panel PN, for example, the first region and the second region, are all controlled to a wide viewing mode (Share mode), and the second mode may correspond to a mode in which a plurality of regions of the display panel PN, for example, at least a portion of the first region and the second region, for example, the second region, is driven in a narrow viewing mode (Private mode).

[0075] For example, when the display device 100 is driven in the first mode and the second mode, the first region of the display panel PN may be driven in the third state under the control of the mode controller MS. In this case, all of the first-type light-emitting elements and the second-type light-emitting elements included in each of the first pixels arranged on the first region of the display panel PN may emit light. As a result, light generated from the first-type light-emitting elements included in each of the first pixels may be emitted at a first viewing angle through the first lens, and light generated from the second-type light-emitting elements included in each of the first pixels may be emitted at a first viewing angle through the second lens. Therefore, when the display device 100 is driven in the first mode and the second mode, wide-viewing mode content may be provided from the first pixels arranged on the first region of the display panel PN.

[0076] Furthermore, when the display device 100 is driven in the first mode, the second region of the display panel PN may be driven in a first state under the control of the mode controller MS. In this case, the first-type light-emitting elements included in each of the second pixels arranged on the second region of the display panel PN may emit light, and the second-type light-emitting elements may not emit light. This allows light generated from the first-type light-emitting elements included in each of the second pixels to be emitted at a first viewing angle through the third lens. Therefore, when the display device 100 is driven in the first mode, wide-viewing mode content may be provided from the second pixels arranged on the second region of the display panel PN.

[0077] Furthermore, when the display device 100 is driven in the second mode, the second region of the display panel PN may be driven in a second state under the control of the mode controller MS. In this case, the second-type light-emitting elements included in each of the second pixels arranged on the second region of the display panel PN may emit light, and the first-type light-emitting elements may not emit light. This allows light generated from the second-type light-emitting elements included in each of the second pixels to be emitted at a second viewing angle through the fourth lens. Therefore, when the display device 100 is driven in the second mode, narrow viewing mode content may be provided from the second pixels arranged on the second region of the display panel PN.

[0078] A detailed description of the configuration in which the mode controller MS controls the display panel PN to the first mode or the second mode depending on the driving mode of the display device 100 will be given later with reference to FIGS.

[0079] FIG. 3 is a circuit diagram showing an example of a pixel circuit of a display device according to an embodiment of the present specification.

[0080] On the other hand, FIG. 3 shows an example of a pixel circuit SPC corresponding to each of the plurality of pixels PX of the display device 100. In FIG.

[0081] Referring to FIG. 3, the pixel circuit SPC may include a driving circuit DC, a selection circuit SC, and a plurality of light emitting elements EDa and EDb.

[0082] The driving circuit DC may include a driving transistor DT, a switching transistor ST, and a first capacitor C1.

[0083] The driving transistor DT and the first capacitor C1 may be connected to the switching transistor ST. A first electrode of the driving transistor DT may be connected to a first power line providing a first power supply voltage VDD, for example, a high potential power supply voltage.

[0084] The switching transistor ST is connected to the gate line GL and receives a gate signal. The switching transistor ST can be turned on or off in response to the gate signal. A first electrode of the switching transistor ST can be connected to the data line DL. In this case, when the switching transistor ST is turned on, a data signal can be supplied to the gate electrode of the driving transistor DT through the switching transistor ST.

[0085] The first capacitor C1 may be disposed between the gate electrode and the second electrode of the driving transistor DT, and may maintain a signal, such as a data signal, applied to the gate electrode of the driving transistor DT for one frame.

[0086] The selection circuit SC may include a first selection transistor TP1 for generating a current path for a first drive current through the first type light-emitting element EDa, and a second selection transistor TP2 for generating a current path for a second drive current through the second type light-emitting element EDb.

[0087] The first selection transistor TP1 is disposed between the drive circuit DC and the first-type light-emitting element EDa, and the gate electrode of the first selection transistor TP1 may be connected to a first-type selection signal line that provides a first selection signal Ss. When the pixel circuit SPC is driven in the first state or the third state, if the first selection signal Ss is supplied to the gate electrode of the first selection transistor TP1, the first selection transistor TP1 is turned on, and a current path for the first driving current passing through the first-type light-emitting element EDa may be formed. In this case, the first-type light-emitting element EDa can emit light.

[0088] The second selection transistor TP2 is disposed between the drive circuit DC and the second-type light-emitting element EDb, and the gate electrode of the second selection transistor TP2 may be connected to a second-type selection signal line that provides a second selection signal Ps. When the pixel circuit SPC is driven in the second state or the third state, if the second selection signal Ps is supplied to the gate electrode of the second selection transistor TP2, the second selection transistor TP2 is turned on, and a current path for the second driving current passing through the second-type light-emitting element EDb may be formed. In this case, the second-type light-emitting element EDb can emit light.

[0089] The first-type light emitting element EDa may be connected between a first selection transistor TP1 that is turned on or off by a first selection signal Ss and a second power supply line that provides a second power supply voltage VSS, e.g., a low potential power supply voltage. The second-type light emitting element EDb may be connected between a second selection transistor TP2 that is turned on or off by a second selection signal Ps and a second power supply line that provides a second power supply voltage VSS, e.g., a low potential power supply voltage.

[0090] In this case, the first-type light-emitting element EDa or the second-type light-emitting element EDb may be connected to another component of the pixel circuit SPC, for example, the drive transistor DT of the drive circuit DC, depending on the drive mode, where the drive mode may be specified by a user input or may be determined when a pre-specified condition is met.

[0091] For example, the driving mode may include a first mode in which all of the multiple regions of the display panel PN described with reference to FIG. 2 are controlled to a wide-view mode (Share mode), and a second mode in which at least a portion of the multiple regions of the display panel PN, for example, the second region, is driven in a narrow-view mode (Private mode).

[0092] The first-type light emitting element EDa and the second-type light emitting element EDb included in one pixel circuit SPC can embody the same color.

[0093] The transistors DT, ST, TP1, and TP2 in FIG. 3 may include at least one of amorphous silicon, polycrystalline silicon, and an oxide semiconductor such as IGZO. The first electrode or the second electrode of the transistor may be a source electrode or a drain electrode. For example, the first electrode may be a source electrode and the second electrode may be a drain electrode. For another example, the first electrode may be a drain electrode and the second electrode may be a source electrode.

[0094] FIG. 4 is a circuit diagram showing an example of a pixel circuit of a display device according to an embodiment of the present specification.

[0095] Meanwhile, FIG. 4 may show an exemplary pixel circuit SPC_1 applicable to the pixel circuit SPC shown in FIG.

[0096] 4, at least some of the transistors included in pixel circuit SPC_1 may be n-type transistors or p-type transistors. In the case of p-type transistors, the low level voltage of each driving signal may represent a voltage that turns on the TFT, and the high level voltage of each driving signal may represent a voltage that turns off the TFT.

[0097] Here, the low-level voltage may correspond to a pre-specified voltage lower than the high-level voltage. For example, the low-level voltage may include a voltage within a range of -8V to -12V. The high-level voltage may correspond to a pre-specified voltage higher than the low-level voltage. For example, the high-level voltage may include a voltage within a range of 12V to 16V. Depending on the embodiment, the low-level voltage may be referred to as a first voltage, and the high-level voltage may be referred to as a second voltage. In this case, the first voltage may be lower than the second voltage.

[0098] Hereinafter, the first electrode or second electrode of a transistor may refer to a source electrode or a drain electrode. However, the terms "first electrode" and "second electrode" are merely terms used to distinguish between the electrodes and do not limit what each electrode corresponds to. Furthermore, the "first electrode" may not refer to the same electrode for each electrode.

[0099] The pixel circuit SPC_1 may include a drive circuit DC_1, a selection circuit SC_1, and a plurality of light emitting elements EDa and EDb.

[0100] The driving circuit DC_1 may include a driving transistor DT, a plurality of switching transistors ST1 to ST5, and a second capacitor C2.

[0101] The driving transistor DT controls the driving current applied to the light emitting elements EDa and EDb according to a source-gate voltage. The driving transistor DT includes a source electrode connected to a first power line providing a first power supply voltage VDD, for example, a high potential power supply voltage, a gate electrode connected to a second node N2, and a drain electrode connected to a third node N3.

[0102] The first switching transistor ST1 can apply a data signal from the data line DL to the first node N1. The first switching transistor ST1 includes a source electrode connected to the data line DL, a drain electrode connected to the first node N1, and a gate electrode connected to a first scan signal line SL1 to which a first scan signal SCAN1 is applied. The first switching transistor ST1 can be turned on or off by the first scan signal SCAN1. Thus, the first switching transistor ST1 can apply the data signal from the data line DL to the first node N1 in response to the first scan signal SCAN1 at a low level, which is a turn-on level.

[0103] The second switching transistor ST2 can diode-connect the gate electrode and drain electrode of the driving transistor DT. The second switching transistor ST2 includes a drain electrode connected to a second node N2, a source electrode connected to a third node N3, and a gate electrode connected to a second scan signal line SL2 to which a second scan signal SCAN2 is applied. The second switching transistor ST2 can be turned on or off in response to the second scan signal SCAN2 at a low level, which is a turn-on level. Therefore, the second switching transistor ST2 can diode-connect the gate electrode and drain electrode of the driving transistor DT.

[0104] The third switching transistor ST3 can apply a reference voltage Vref to the first node N1. The third switching transistor ST3 includes a source electrode connected to a reference voltage line providing the reference voltage Vref, a drain electrode connected to the first node N1, and a gate electrode connected to an emission signal line EL to which an emission signal EM is applied. The third switching transistor ST3 can be turned on or off by the emission signal EM. Thus, the third switching transistor ST3 can transfer the reference voltage Vref to the first node N1 in response to the emission signal EM being at a low level, which is a turn-on level.

[0105] The fourth switching transistor ST4 can apply the reference voltage Vref to the anode electrode of the first-type light-emitting element EDa. The fourth switching transistor ST4 includes a source electrode connected to a reference voltage line providing the reference voltage Vref, a drain electrode connected to the anode electrode of the first-type light-emitting element EDa, and a gate electrode connected to a second scan signal line SL2 to which a second scan signal SCAN2 is applied. The fourth switching transistor ST4 can be turned on or off by the second scan signal SCAN2. Therefore, the fourth switching transistor ST4 can apply the reference voltage Vref to the anode electrode of the first-type light-emitting element EDa in response to the second scan signal SCAN2 being at a low level, which is a turn-on level.

[0106] The fifth switching transistor ST5 applies the reference voltage Vref to the anode electrode of the second-type light-emitting element EDb. The fifth switching transistor ST5 includes a source electrode connected to a reference voltage line providing the reference voltage Vref, a drain electrode connected to the anode electrode of the second-type light-emitting element EDb, and a gate electrode connected to a second scan signal line SL2 to which a second scan signal SCAN2 is applied. The fifth switching transistor ST5 can be turned on or off by the second scan signal SCAN2. Therefore, the fifth switching transistor ST5 can apply the reference voltage Vref to the anode electrode of the second-type light-emitting element EDb in response to the second scan signal SCAN2 being at a low level, which is a turn-on level.

[0107] The second capacitor C2 may include a first electrode connected to the first node N1 and a second electrode connected to the second node N2. That is, one electrode of the second capacitor C2 may be connected to the gate electrode of the driving transistor DT, and the other electrode of the second capacitor C2 may be connected to the first switching transistor ST1. The second capacitor C2 stores a constant voltage to maintain a constant voltage at the gate electrode of the driving transistor DT while at least one of the light emitting elements EDa and EDb is emitting light.

[0108] The selection circuit SC_1 may include a first selection transistor TP1 for generating a current path for a first driving current passing through a first type light-emitting element EDa, and a second selection transistor TP2 for generating a current path for a second driving current passing through a second type light-emitting element EDb.

[0109] The first selection transistor TP1 is disposed between the drive circuit DC_1 and the first-type light-emitting element EDa, and the gate electrode of the first selection transistor TP1 may be connected to a first-type selection signal line that provides a first selection signal Ss. When the pixel circuit SPC_1 is driven in the first state or the third state, if the first selection signal Ss is supplied to the gate electrode of the first selection transistor TP1, the first selection transistor TP1 is turned on, and a current path for a first driving current passing through the first-type light-emitting element EDa may be formed. In this case, the first-type light-emitting element EDa can emit light.

[0110] The second selection transistor TP2 is disposed between the drive circuit DC_1 and the second-type light-emitting element EDb, and the gate electrode of the second selection transistor TP2 may be connected to a second-type selection signal line that provides a second selection signal Ps. When the pixel circuit SPC_1 is driven in the second state or the third state, if the second selection signal Ps is supplied to the gate electrode of the second selection transistor TP2, the second selection transistor TP2 is turned on, and a current path for the second driving current passing through the second-type light-emitting element EDb may be formed. In this case, the second-type light-emitting element EDb can emit light.

[0111] The first-type light emitting element EDa may be connected between a first selection transistor TP1 that is turned on or off by a first selection signal Ss and a second power supply line that provides a second power supply voltage VSS, e.g., a low potential power supply voltage. The second-type light emitting element EDb may be connected between a second selection transistor TP2 that is turned on or off by a second selection signal Ps and a second power supply line that provides a second power supply voltage VSS, e.g., a low potential power supply voltage.

[0112] In this case, the first-type light-emitting element EDa or the second-type light-emitting element EDb may be connected to another component of the pixel circuit SPC_1, for example, the driving transistor DT of the driving circuit DC_1, depending on the driving mode, where the driving mode may be specified by a user input or may be determined when a predetermined condition is met.

[0113] The first-type light emitting element EDa and the second-type light emitting element EDb included in one pixel circuit SPC_1 can embody the same color.

[0114] 5a and 5b are waveform diagrams for explaining the pixel circuit of FIG.

[0115] On the other hand, Figure 5a shows a waveform diagram for explaining an example when pixel circuit SPC_1 is driven in the first state, and Figure 5b shows a waveform diagram for explaining an example when pixel circuit SPC_1 is driven in the second state.

[0116] 4 to 5b, when the pixel circuit SPC_1 is driven in a first state, only the first-type light-emitting element EDa emits light, and when the pixel circuit SPC_1 is driven in a second state, only the second-type light-emitting element EDb emits light. Here, as shown in FIG. 5a, in the first state, the second select signal Ps for controlling the emission of the second-type light-emitting element EDb, i.e., the second select signal Ps for forming a current path for the second driving current, can be output only at a high level, which is a turn-off level, so that only the first-type light-emitting element EDa emits light. Also, as shown in FIG. 5b, in the second state, the first select signal Ss for controlling the emission of the first-type light-emitting element EDa, i.e., the first select signal Ss for forming a current path for the first driving current, can be output only at a high level, which is a turn-off level, so that only the second-type light-emitting element EDb emits light.

[0117] 4 and 5a, considering the case where the pixel circuit SPC_1 operates in the first state, a low-level second scan signal SCAN2, a low-level first select signal Ss, and a low-level light-emitting signal EM may be output during the initialization period. The low-level second scan signal SCAN2 may turn on the second switching transistor ST2, the fourth switching transistor ST4, and the fifth switching transistor ST5, the low-level first select signal Ss may turn on the first selection transistor TP1, and the low-level light-emitting signal EM may turn on the third switching transistor ST3.

[0118] The first node N1 may be initialized to the reference voltage Vref through the turned-on third switching transistor ST3. The voltage of the anode electrode of the first-type light emitting element EDa may be initialized to the reference voltage Vref through the turned-on fourth switching transistor ST4, and the voltage of the anode electrode of the second-type light emitting element EDb may be initialized to the reference voltage Vref through the turned-on fifth switching transistor ST5. The drive transistor DT is diode-connected through the turned-on second switching transistor ST2, and the gate electrode and drain electrode of the drive transistor DT are shorted, allowing the drive transistor DT to operate like a diode. The reference voltage Vref transferred to the anode electrode of the first-type light emitting element EDa through the turned-on fourth switching transistor ST4 is transferred to the third node N3 and the second node N2 through the turned-on first selection transistor TP1, and the third node N3 and the second node N2 may be initialized to the reference voltage Vref.

[0119] Next, during a sampling period, the first scan signal SCAN1 and the second scan signal SCAN2 are output at a low level, and the first select signal Ss is output at a high level. The light-emitting signal EM is output at a high level, turning off the third switching transistor ST3. At the same time, the first switching transistor ST1 is turned on by the first scan signal SCAN1 at a low level, and a data signal is transmitted to the first node N1. The driving transistor DT is diode-coupled by the turned-on second switching transistor ST2, and a difference voltage between the first power supply voltage VDD and the threshold voltage is sampled and supplied to the second node N2.

[0120] During the holding period, the first scan signal SCAN1 and the second scan signal SCAN2 are output at a high level, and the first switching transistor ST1, the second switching transistor ST2, the fourth switching transistor ST4, and the fifth switching transistor ST5 are all turned off. However, even if the first switching transistor ST1 is turned off, the data signal (data voltage) input during the previous period (e.g., the sampling period) may be maintained by the second capacitor C2.

[0121] Finally, during the light-emitting period, the first select signal Ss and the light-emitting signal EM are output at a low level, and the second select signal Ps is output at a high level. The reference voltage Vref is applied to the first node N1 through the third switching transistor ST3, which is turned on by the light-emitting signal EM at a low level. The voltage at the first node N1 may be the difference voltage between the reference voltage Vref and the data signal (data voltage), and this voltage fluctuation may also be reflected at the second node N2. The gate-source voltage of the drive transistor DT may be set to a value obtained by subtracting the reference voltage Vref from the data signal (data voltage) and adding the data signal (data voltage), (Vdata-Vref+Vth), thereby controlling the first drive current.

[0122] Then, the first driving current is supplied from the driving transistor DT to the first-type light emitting element EDa through the turned-on first selection transistor TP1, allowing the first-type light emitting element EDa to emit light. However, the second selection signal Ps is output at a high level, turning off the second selection transistor TP2, preventing the second driving current from being transmitted from the driving transistor DT to the second-type light emitting element EDb. Therefore, when the pixel circuit SPC_1 is driven in the first state, the first driving current is applied only to the first-type light emitting element EDa, allowing only the first-type light emitting element EDa to emit light.

[0123] 4 and 5b, the pixel circuit SPC_1 may be driven in the second state in substantially the same manner as the first state, except that the first selection signal Ss and the second selection signal Ps are output in the opposite manner to those in the first state. That is, the first selection signal Ss may be output only at a high level, which is a turn-off level, and the second selection signal Ps may be output at a low level, which is a turn-on level, during an emission period in which the second-type light-emitting element EDb emits light.

[0124] Specifically, during the initialization period, the first scan signal SCAN1 may be output at a high level, and the second scan signal SCAN2 may be output at a low level. The first select signal Ss may be output at a high level, and the second select signal Ps and the light-emitting signal EM may be output at a low level. The second, fourth, and fifth switching transistors ST2, ST4, and ST5 may be turned on by the second scan signal SCAN2, the second select signal Ps may be turned on by the second select transistor TP2, and the third switching transistor ST3 may be turned on by the light-emitting signal EM.

[0125] The first node N1 is initialized to the reference voltage Vref through the third switching transistor ST3 turned on by the light emitting signal EM, and the anode electrodes of the first-type light emitting element EDa and the second-type light emitting element EDb can be initialized to the reference voltage Vref through the fourth switching transistor ST4 and the fifth switching transistor ST5 turned on by the second scan signal SCAN2. The driving transistor DT is diode-coupled through the turned-on second switching transistor ST2 and can operate like a diode. Finally, the reference voltage Vref transferred to the anode electrode of the second-type light emitting element EDb through the turned-on fifth switching transistor ST5 is transferred to the third node N3 and the second node N2 through the turned-on second selection transistor TP2, and the third node N3 and the second node N2 can be initialized to the reference voltage Vref.

[0126] Next, during a sampling period, the first scan signal SCAN1 and the second scan signal SCAN2 are output at a low level, and the second select signal Ps and the light emitting signal EM are output at a high level. The light emitting signal EM is output at a high level, and the third switching transistor ST3 is turned off. The first switching transistor ST1 is turned on by the first scan signal SCAN1 at a low level, and the data signal is transmitted to the first node N1. The driving transistor DT is diode-coupled by the turned-on second switching transistor ST2, and the difference voltage between the first power supply voltage VDD and the threshold voltage is sampled and supplied to the second node N2.

[0127] Finally, during the light-emitting period, the second selection signal Ps and the light-emitting signal EM are output at a low level, and the first selection signal Ss is output at a high level. The reference voltage Vref is applied to the first node N1 through the third switching transistor ST3, which is turned on by the light-emitting signal EM at a low level. The voltage at the first node N1 may be the difference voltage between the reference voltage Vref and the data signal (data voltage), and this voltage fluctuation may also be reflected at the second node N2. The gate-source voltage of the driving transistor DT may be set to a value obtained by subtracting the reference voltage Vref from the data signal (data voltage) and adding the data signal (data voltage), (Vdata-Vref+Vth), thereby controlling the second driving current.

[0128] Then, the second driving current is supplied from the driving transistor DT to the second-type light emitting element EDb through the turned-on second selection transistor TP2, allowing the second-type light emitting element EDb to emit light. However, the first selection signal Ss is output at a high level, turning off the first selection transistor TP1, preventing the first driving current from being transmitted from the driving transistor DT to the first-type light emitting element EDa. Therefore, when the pixel circuit SPC_1 is driven in the second state, the second driving current is applied only to the second-type light emitting element EDb, allowing only the second-type light emitting element EDb to emit light.

[0129] On the other hand, although not shown in Figures 5a and 5b, when the pixel circuit SPC_1 is driven in the third state, the first-type light-emitting element EDa and the second-type light-emitting element EDb all emit light, so the waveform of the first selection signal Ss in the third state and the operation of the pixel circuit SPC_1 in which the first driving current is formed thereby, and the waveform of the first selection signal Ss in the first state and the operation of the pixel circuit SPC_1 in which the first driving current is formed thereby, described with reference to Figure 5a, are substantially identical or similar, and the waveform of the second selection signal Ps in the third state and the operation of the pixel circuit SPC_1 in which the second driving current is formed thereby, and the waveform of the second selection signal Ps in the second state and the operation of the pixel circuit SPC_1 in which the second driving current is formed thereby, described with reference to Figure 5b, are substantially identical or similar, so redundant description will not be repeated.

[0130] 6 and 7 are cross-sectional views of a display device according to an embodiment of the present specification.

[0131] FIG. 6 shows a pixel in which a first type lens 161 is arranged, and FIG. 7 shows a pixel in which a second type lens 162 is arranged.

[0132] Referring to Figures 6 and 7, the display device 100 according to an embodiment of the present specification may include a substrate 110, a buffer film 111, a gate insulating film 112, an interlayer insulating film 113, a lower protective film 114, an overcoat layer 115, a bank insulating film 116, a first selection transistor TP1, a second selection transistor TP2, a first type light-emitting element EDa, a second type light-emitting element EDb, a first type lens 161, a second type lens 162, a lens protection film 170 and a sealing member 180.

[0133] The substrate 110 may include an insulating material. The substrate 110 may include a transparent material. For example, the substrate 110 may include glass or plastic.

[0134] A buffer film 111 may be disposed on the substrate 110. The buffer film 111 may include an insulating material. For example, the buffer film 111 may include an inorganic insulating material such as silicon oxide (SiOx) and silicon nitride (SiNx). The buffer film 111 may have a multi-layer structure. For example, the buffer film 111 may have a stacked structure of a film made of silicon nitride (SiNx) and a film made of silicon oxide (SiOx).

[0135] The buffer film 111 may be located between the substrate 110 and a driving portion of each pixel PX, such as a driving circuit DC. The buffer film 111 can prevent contamination by the substrate 110 during the process of forming the driving portion. For example, the upper surface of the substrate 110 facing the driving portion of each pixel PX may be covered with the buffer film 111. The driving portion of each pixel PX may be located on the buffer film 111.

[0136] A gate insulating layer 112 may be disposed on the buffer layer 111. The gate insulating layer 112 may include an insulating material. For example, the gate insulating layer 112 may include an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN). The gate insulating layer 112 may include a material having a high dielectric constant. For example, the gate insulating layer 112 may include a high-K material such as hafnium oxide (HfO). The gate insulating layer 112 may have a multi-layer structure.

[0137] The gate insulating film 112 may extend between the semiconductor layers 121, 221 and the gate electrodes 122, 223 of the selection transistors TP1, TP2. For example, the gate electrodes of the driving transistor DT and the switching transistor ST may be insulated from the semiconductor layers of the driving transistor DT and the switching transistor ST by the gate insulating film 112. The gate insulating film 112 may cover the semiconductor layers of each pixel PX. The gate electrodes of the driving transistor DT and the switching transistor ST may be located on the gate insulating film 112.

[0138] An interlayer insulating film 113 may be disposed on the gate insulating film 112. The interlayer insulating film 113 may include an insulating material. For example, the interlayer insulating film 113 may include an inorganic insulating material such as silicon dioxide (SiO) and silicon nitride (SiN). The interlayer insulating film 113 may extend between the gate electrode and source electrode and between the gate electrode and drain electrode of each of the driving transistor DT and the switching transistor ST. For example, the source electrode and drain electrode of each of the driving transistor DT and the switching transistor ST may be insulated from the gate electrode by the interlayer insulating film 113. The interlayer insulating film 113 may cover the gate electrodes of the driving transistor DT and the switching transistor ST. The source electrode and drain electrode of each pixel PX may be located on the interlayer insulating film 113. The gate insulating film 112 and the interlayer insulating film 113 may expose the source region and drain region of each semiconductor pattern located in each pixel PX.

[0139] A lower passivation layer 114 may be disposed on the interlayer insulating layer 113. The lower passivation layer 114 may include an insulating material. For example, the lower passivation layer 114 may include an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN). The lower passivation layer 114 may prevent damage to the driving portions due to external moisture and impact. The lower passivation layer 114 may extend along surfaces of the driving transistor DT and the switching transistor ST facing the substrate 110. The lower passivation layer 114 may contact the interlayer insulating layer 113 outside the driving portions located in each pixel PX.

[0140] An overcoat layer 115 may be disposed on the lower passivation layer 114. The overcoat layer 115 may include an insulating material. The overcoat layer 115 may include a material different from that of the lower passivation layer 114. For example, the overcoat layer 115 may include an organic insulating material. The overcoat layer 115 may remove steps caused by driving portions of each pixel PX. For example, the top surface of the overcoat layer 115 facing the device substrate 110 may be a flat surface.

[0141] A first selection transistor TP1 and a second selection transistor TP2 may be disposed on the substrate 110. The first selection transistor TP1 may be electrically connected between the drain electrode of the driving transistor DT and the first bottom electrode 141 of the first-type light-emitting element EDa. The second selection transistor TP2 may be electrically connected between the drain electrode of the driving transistor DT and the second bottom electrode 151 of the second-type light-emitting element EDb.

[0142] The first selection transistor TP1 may include a first semiconductor layer 121, a first gate electrode 122, a first source electrode 123, and a first drain electrode 124. The first selection transistor TP1 may have the same structure as the switching transistor ST and the driving transistor DT. For example, the first semiconductor layer 121 may be located between the buffer film 111 and the gate insulating film 112, and the first gate electrode 122 may be located between the gate insulating film 112 and the interlayer insulating film 113. The first source electrode 123 and the first drain electrode 124 may be located between the interlayer insulating film 113 and the lower passivation film 114. The first gate electrode 122 may overlap a channel region of the first semiconductor layer 121. The first source electrode 123 may be electrically connected to a source region of the first semiconductor layer 121. The first drain electrode 124 may be electrically connected to a drain region of the first semiconductor layer 121.

[0143] The second selection transistor TP2 may include a second semiconductor layer 221, a second gate electrode 223, a second source electrode 225, and a second drain electrode 227. For example, the second semiconductor layer 221 may be located in the same layer as the first semiconductor layer 121, the second gate electrode 223 may be located in the same layer as the first gate electrode 122, and the second source electrode 225 and the second drain electrode 227 may be located in the same layer as the first source electrode 123 and the first drain electrode 124.

[0144] The first-type light-emitting element EDa and the second-type light-emitting element EDb of each pixel PX may be disposed on the overcoat layer 115 of the corresponding pixel PX.

[0145] The first-type light emitting element EDa may emit light of a specific color. For example, the first-type light emitting element EDa may include a first lower electrode 141, a first light emitting layer 142, and a first upper electrode 143, which are sequentially stacked on a substrate 110.

[0146] The first lower electrode 141 may include a conductive material. The first lower electrode 141 may include a material having high reflectivity. For example, the first lower electrode 141 may include a metal such as aluminum (Al) or silver (Ag). The first lower electrode 141 may have a multi-layer structure. For example, the first lower electrode 141 may have a structure in which a reflective electrode made of a metal is located between transparent electrodes made of a transparent conductive material such as ITO or IZO. The first lower electrode 141 may be electrically connected to the first drain electrode 124 of the first selection transistor TP1 through a contact hole penetrating the lower passivation layer 114 and the overcoat layer 115.

[0147] The first light-emitting layer 142 can generate light with a brightness corresponding to the voltage difference between the first lower electrode 141 and the first upper electrode 143. For example, the first light-emitting layer 142 can include an emission material layer (EML) containing a light-emitting material. The light-emitting material can include an organic material, an inorganic material, or a hybrid material.

[0148] The first light-emitting layer 142 may have a multi-layer structure. For example, the first light-emitting layer 142 may further include at least one of a hole injection layer (HIL), a hole transport layer (HTL), an electron transport layer (ETL), and an electron injection layer (EIL).

[0149] The first upper electrode 143 may include a conductive material. The first upper electrode 143 may include a different material from the first lower electrode 141. The transmittance of the first upper electrode 143 may be higher than the transmittance of the first lower electrode 141. For example, the first upper electrode 143 may be a transparent electrode made of a transparent conductive material such as ITO or IZO. As a result, in the display device 100 according to the embodiment of the present specification, light generated by the first light emitting layer 142 may be emitted through the first upper electrode 143.

[0150] The second-type light emitting device EDb may embody the same color as the first-type light emitting device EDa. The second-type light emitting device EDb may have the same structure as the first-type light emitting device EDa. For example, the second-type light emitting device EDb may include a second lower electrode 151, a second light emitting layer 152, and a second upper electrode 153, which are sequentially stacked on the substrate 110.

[0151] The second lower electrode 151 may correspond to the first lower electrode 141, the second light-emitting layer 152 may correspond to the first light-emitting layer 142, and the second upper electrode 153 may correspond to the first upper electrode 143. For example, the second lower electrode 151 may be formed with the same structure as the first lower electrode 141 for the second-type light-emitting element EDb, and this is also the same for the second light-emitting layer 152 and the second upper electrode 153. For example, the first-type light-emitting element EDa and the second-type light-emitting element EDb may be formed to have the same structure. However, this is not limited thereto, and in some cases, at least a portion of the configuration of the first-type light-emitting element EDa and the second-type light-emitting element EDb may be formed to be different.

[0152] The second light emitting layer 152 may be spaced apart from the first light emitting layer 142. This may prevent light emission due to leakage current in the display device according to the embodiment of the present disclosure.

[0153] The second lower electrode 151 of each pixel PX may be spaced apart from the first lower electrode 141 of the corresponding pixel PX. For example, a bank insulating layer 116 may be disposed between the first lower electrode 141 and the second lower electrode 151 of each pixel PX. The bank insulating layer 116 may include an insulating material. For example, the bank insulating layer 116 may include an organic insulating material. The bank insulating layer 116 may include a different material from the overcoat layer 115.

[0154] The second lower electrode 151 of each pixel PX may be insulated from the first lower electrode 141 of the corresponding pixel PX by the bank insulating film 116. For example, the bank insulating film 116 may cover an edge of the first lower electrode 141 and an edge of the second lower electrode 151 located in each pixel PX. As a result, in the display device 100, an image based on the first-type lens region LSAa of each pixel PX in which the first-type light-emitting element EDa is located or an image based on the second-type lens region LSAb of each pixel PX in which the second-type light-emitting element EDb is located may be provided to a user.

[0155] The first light-emitting layer 142 and the first upper electrode 143 of the first-type light-emitting element EDa located in each pixel PX may be stacked on a portion of the corresponding first lower electrode 141 exposed by the bank insulating film 116. The second light-emitting layer 152 and the second upper electrode 153 of the second-type light-emitting element EDb located in each pixel PX may be stacked on a portion of the corresponding second lower electrode 151 exposed by the bank insulating film 116. For example, the bank insulating film 116 may divide each pixel PX into a first-type light-emitting region EAa from which light is emitted by the first-type light-emitting element EDa and a second-type light-emitting region EAb from which light is emitted by the second-type light-emitting element EDb. The size of the divided second-type light-emitting region EAb in each pixel PX may be smaller than the size of the first-type light-emitting region EAa.

[0156] The second upper electrode 153 of each pixel PX may be electrically connected to the first upper electrode 143 of the corresponding pixel PX. For example, the voltage applied to the second upper electrode 153 of the second-type light-emitting element EDb located in each pixel PX may be the same as the voltage applied to the first upper electrode 143 of the first-type light-emitting element EDa located in the corresponding pixel PX. The second upper electrode 153 of each pixel PX may include the same material as the first upper electrode 143 of the corresponding pixel PX. For example, the second upper electrode 153 of each pixel PX may be formed simultaneously with the first upper electrode 143 of the corresponding pixel PX. The second upper electrode 153 of each pixel PX may extend on the bank insulating film 116 and be in direct contact with the first upper electrode 143 of the corresponding pixel PX. The luminance of the first-type lens area LSAa and the second-type lens area LSAb located in each pixel PX may be controlled by the driving current generated in the corresponding pixel PX.

[0157] An encapsulating member 180 may be disposed on the first-type light emitting device EDa and the second-type light emitting device EDb of each pixel PX. The encapsulating member 180 may prevent damage to the light emitting devices EDa and EDb due to external moisture and impact. The encapsulating member 180 may have a multi-layer structure. For example, the encapsulating member 180 may include, but is not limited to, a first encapsulating layer 181, a second encapsulating layer 182, and a third encapsulating layer 183 stacked in order. The first encapsulating layer 181, the second encapsulating layer 182, and the third encapsulating layer 183 may include an insulating material. The second encapsulating layer 182 may include a different material from the first encapsulating layer 181 and the third encapsulating layer 183. For example, the first encapsulating layer 181 and the third encapsulating layer 183 may be inorganic encapsulating layers including an inorganic insulating material, and the second encapsulating layer 182 may include an organic encapsulating layer including an organic insulating material. This may more effectively prevent damage to the light emitting device ED of the display device 100 due to external moisture and impact.

[0158] A first type lens 161 and a second type lens 162 may be disposed on the sealing member 180 .

[0159] The first-type lenses 161 may be disposed on the first-type light-emitting elements EDa. Light generated by the first-type light-emitting elements EDa of each pixel PX may be emitted through the first-type lenses 161 of the corresponding pixel PX. The first-type lenses 161 may have a shape that does not restrict light in at least one lateral direction. For example, the planar shape of the first-type lenses 161 located in each pixel PX may have a bar shape extending in one direction.

[0160] In this case, the traveling direction of light emitted from the first-type lens area LSAa of each pixel PX is not limited to one direction. For example, content (or an image) provided through the first-type lens area LSAa of each pixel PX can be shared with the user and people nearby in one direction. As a result, content provided by light emitted through the first-type lens 161 can be provided in a first viewing angle range, which is a wider viewing angle than content provided by light emitted through the second-type lens 162. For example, content provided by light emitted through the first-type lens 161 can be provided in a wide-viewing mode (Share mode).

[0161] The second-type lens 162 may be disposed on the second-type light-emitting element EDb. Light generated by the second-type light-emitting element EDb in each pixel PX may be emitted through the second-type lens 162 in the corresponding pixel PX. The second-type lens 162 may limit the traveling direction of the light passing therethrough to one direction and / or another direction. For example, the planar shape of the second-type lens 162 located in each pixel PX may be circular.

[0162] In this case, the traveling direction of light emitted from the second-type lens region LSAb of each pixel PX may be limited to one direction and / or another direction. For example, the content (or image) provided by the second-type lens region LSAb of each pixel PX may not be shared with people around the user. As a result, the content provided by light emitted through the second-type lens 162 may be provided in a second viewing angle range, which is a narrower viewing angle than the content provided by light emitted through the first-type lens 161. For example, the content provided by light emitted through the second-type lens 162 may be provided in a narrow viewing mode (Private mode).

[0163] The first-type light-emitting region EAa of each pixel PX may have a shape corresponding to the first-type lens 161 of the corresponding pixel PX. For example, the planar shape of the first-type light-emitting region EAa of each pixel PX may be a bar shape extending in one direction. The first-type lens 161 may be larger than the first-type light-emitting region EAa of the corresponding pixel PX. This may improve the efficiency of light emitted from the first-type light-emitting region EAa of the pixel PX.

[0164] The second-type light-emitting region EAb of each pixel PX may have a shape corresponding to the second-type lens 162 of the corresponding pixel PX. For example, the planar shape of the second-type light-emitting region EAb of each pixel PX may be circular. The second-type lens 162 may have a larger size than the second-type light-emitting region EAb of the corresponding pixel PX. This may improve the efficiency of light emitted from the second-type light-emitting region EAb of the pixel PX.

[0165] 6, when a pixel PX includes a first-type lens 161, a first-type lens area LSAa in which the first-type lens 161 is disposed may include one light-emitting area, for example, one first-type light-emitting area EAa. Also, when a pixel PX includes a second-type lens 162, a second-type lens area LSAb in which the second-type lens 162 is disposed may include multiple light-emitting areas, for example, multiple second-type light-emitting areas EAb.

[0166] 6, when the pixel PX includes the first-type lens 161, one first-type lens 161 may be disposed on the first-type lens area LSAa. Thus, the first-type light-emitting area EAa of the first-type light-emitting element EDa defined by the bank insulating film 116 may be one corresponding to one first-type lens 161.

[0167] 7, when the pixel PX includes the second-type lens 162, two second-type lenses 162 may be disposed on the second-type lens region LSAb. Thus, the second-type light-emitting region EAb of the second-type light-emitting element EDb defined by the bank insulating film 116 may be two, corresponding to the two second-type lenses 162.

[0168] A lens protection film 170 may be disposed on the first-type lenses 161 and the second-type lenses 162 of the pixel PX. The lens protection film 170 may include an insulating material. For example, the lens protection film 170 may include an organic insulating material. The refractive index of the lens protection film 170 may be smaller than the refractive index of the first-type lenses 161 and the second-type lenses 162 disposed in each pixel PX. As a result, in the display device 100 according to the embodiment of the present specification, light passing through the first-type lenses 161 and the second-type lenses 162 of each pixel PX is not reflected toward the substrate 110 due to the difference in refractive index between the lens protection film 170 and the lens protection film 170.

[0169] Referring to Figures 6 and 7, as described above, the pixel PX may include, but is not limited to, a first type lens 161 arranged on top of the first type light-emitting element EDa and a second type lens 162 arranged on top of the second type light-emitting element EDb.

[0170] For example, the pixel PX may include a plurality of first-type lenses 161 disposed above the first-type light-emitting element EDa and the second-type light-emitting element EDb, respectively, which will be described in detail below with reference to FIGS.

[0171] 8a and 8b are circuit diagrams and a plan view, respectively, illustrating an example of a first pixel of a display device according to an embodiment of the present disclosure.

[0172] On the other hand, FIGS. 8a and 8b show an example of a first pixel PX1 among a plurality of pixels PX arranged on a display panel PN of a display device 100 according to an embodiment of the present specification described with reference to FIG.

[0173] Meanwhile, the first pixel PX1 shown in FIG. 8a may include the pixel circuit SPC described with reference to FIG. 3 or the pixel circuit SPC_1 described with reference to FIG. 4, and therefore, redundant description of the content described with reference to FIG. 3 and FIG. 4 will not be repeated.

[0174] 8a and 8b, only the selection circuit, the light-emitting elements, and the lenses included in the first pixel PX1 are shown. In FIG. 8a, the correspondence between the lenses is indicated by dotted lines.

[0175] First, referring to FIGS. 3, 4 and 8a, a first pixel PX1 may include a first selection circuit SC1 and a plurality of light emitting elements ED1 and ED2.

[0176] The first selection circuit SC1 may include a first transistor T1 and a second transistor T2, which may correspond to the first selection transistor TP1 and the second selection transistor TP2 described with reference to FIGS.

[0177] The gate electrode of the first transistor T1 may be turned on or off in response to a select signal provided from a first select signal line SSL1, and the gate electrode of the second transistor T2 may be turned on or off in response to a select signal provided from a second select signal line SSL2. Here, the select signal provided from the first select signal line SSL1 and the select signal provided from the second select signal line SSL2 may be, but are not limited to, the first select signal Ss and the second select signal Ps described with reference to FIGS. 3 and 4, respectively.

[0178] The plurality of light-emitting elements ED1 and ED2 included in the first pixel PX1 may include a first light-emitting element ED1 and a second light-emitting element ED2. Substantially the same as or similar to those described with reference to FIGS. 3 and 4, the first light-emitting element ED1 of the first pixel PX1 may be connected between the first transistor T1 and a second power supply line providing a second power supply voltage VSS (e.g., a low-potential power supply voltage), and the second light-emitting element ED2 of the first pixel PX1 may be connected between the second transistor T2 and a second power supply line providing the second power supply voltage VSS. For example, the first light-emitting element ED1 and the second light-emitting element ED2 of FIG. 8a may be light-emitting elements corresponding to the first-type light-emitting element EDa and the second-type light-emitting element EDb described with reference to FIGS. 3 and 4, respectively.

[0179] As a result, when the first transistor T1 is turned on in response to a turn-on level selection signal provided from the first selection signal line SSL1, a first driving current is formed through the first light-emitting element ED1, allowing the first light-emitting element ED1 of the first pixel PX1 to emit light.

[0180] In addition, when the second transistor T2 is turned on in response to a turn-on level selection signal provided from the second selection signal line SSL2, a second driving current is formed through the second light-emitting element ED2, allowing the second light-emitting element ED2 of the first pixel PX1 to emit light.

[0181] The first pixel PX1 can be driven in a third state in which both the first light emitting element ED1 and the second light emitting element ED2 emit light.

[0182] The first pixel PX1 may include a first lens LS1 disposed above the first light-emitting element ED1 and a second lens LS2 disposed above the second light-emitting element ED2.

[0183] To explain the first lens LS1 and the second lens LS2 in more detail, referring further to FIG. 8b, the first pixel PX1 may include a first lens area LSA1 and a second lens area LSA2 in which the first light-emitting element ED1 and the second light-emitting element ED2 are located, respectively.

[0184] The first lens area LSA1 and the second lens area LSA2 can provide images through substantially the same viewing angle, and the luminance of the first lens area LSA1 can be controlled by a first driving current generated by the first light-emitting element ED1, and the luminance of the second lens area LSA2 can be controlled by a second driving current generated by the second light-emitting element ED2.

[0185] The first lens LS1 may be located above the first light-emitting element ED1, and the second lens LS2 may be located above the second light-emitting element ED2.

[0186] The first lens LS1 and the second lens LS2 may each have a first shape. The first lens LS1 and the second lens LS2 may each have a shape that does not restrict light in at least one direction. For example, the planar shape of the first lens LS1 and the second lens LS2 located within the first pixel PX1 may each have a bar shape extending in one direction. As an example, the first lens LS1 and the second lens LS2 may each be embodied as the first type lens 161 described with reference to FIG. 6.

[0187] In this case, if the light generated by the first light-emitting element ED1 of the first pixel PX1 is emitted through the first lens LS1 or the light generated by the second light-emitting element ED2 is emitted through the second lens LS2, the direction of travel of the light is not limited to one direction.

[0188] The first light-emitting area EA1 defined by the first light-emitting element ED1 of the first pixel PX1 may have a shape corresponding to the first lens LS1, and the second light-emitting area EA2 defined by the second light-emitting element ED2 of the first pixel PX1 may have a shape corresponding to the second lens LS2.

[0189] 8b, the planar shapes of the first light-emitting region EA1 and the second light-emitting region EA2 may have a bar shape extending in one direction to correspond to the shapes of the first lens LS1 and the second lens LS2, respectively. In this case, the first lens LS1 located in the first lens region LSA1 may be larger than the first light-emitting region EA1 included in the first lens region LSA1, and the second lens LS2 located in the second lens region LSA2 may be larger than the second light-emitting region EA2 included in the second lens region LSA2. This may improve the efficiency of light emitted from the first light-emitting region EA1 and the second light-emitting region EA2 of the first pixel PX1.

[0190] Since the first lens LS1 and the second lens LS2 are embodied as the first type lens 161, as described with reference to FIG. 6, the first lens area LSA1 and the second lens area LSA2 each include one light-emitting area, for example, one first light-emitting area EA1 and one second light-emitting area EA2, and one lens, for example, one first lens LS1 and one second lens LS2.

[0191] Therefore, when a first driving current is formed in the first pixel PX1 and the first light emitting element ED1 emits light, the light generated by the first light emitting element ED1 of the first pixel PX1 is emitted through the first lens LS1 implemented in the first type lens 161. Therefore, content provided by the light generated by the first light emitting element ED1 of the first pixel PX1 may be provided at a first viewing angle. For example, the provided content (or image) may be shared with people nearby in one direction from the user. Thus, the content provided by the light emitted through the first lens LS1 may be provided in a wide viewing mode (Share mode).

[0192] Furthermore, when a second driving current is formed in the first pixel PX1 and the second light-emitting element ED2 emits light, the light generated by the second light-emitting element ED2 of the first pixel PX1 is emitted through the second lens LS2 implemented in the first type lens 161. Therefore, content provided by the light generated by the second light-emitting element ED2 of the first pixel PX1 may be provided at a first viewing angle. For example, the provided content (or image) may be shared with people nearby in one direction from the user. Thus, the content provided by the light emitted through the second lens LS2 may be provided in a wide viewing mode (Share mode).

[0193] That is, in the case of the first pixel PX1, the content provided by the light generated by the first light emitting element ED1 and the content provided by the light generated by the second light emitting element ED2 may both be provided at the first viewing angle.

[0194] As described above, the first pixel PX1 may be driven in a third state in which both the first and second light-emitting elements ED1 and ED2 emit light. When the first pixel PX1 is driven in the third state, content may be provided at a first viewing angle by the light generated by the first and second light-emitting elements ED1 and ED2.

[0195] In this way, the first region in which the first pixel PX1 driven in the third state is arranged among the plurality of regions of the display panel PN can provide content in the wide viewing mode regardless of the driving mode.

[0196] 9a and 9b are circuit diagrams and a plan view, respectively, illustrating an example of a second pixel of a display device according to an embodiment of the present disclosure.

[0197] On the other hand, FIGS. 9a and 9b show an example of a second pixel PX2 among the plurality of pixels PX arranged on the display panel PN of the display device 100 according to one embodiment of the present specification described with reference to FIG.

[0198] Meanwhile, the second pixel PX2 shown in FIG. 9a may include the pixel circuit SPC described with reference to FIG. 3 or the pixel circuit SPC_1 described with reference to FIG. 4, and therefore, redundant description of the content described with reference to FIG. 3 and FIG. 4 will not be repeated.

[0199] 9a and 9b, only the selection circuit, the light-emitting elements, and the lenses included in the second pixel PX2 are shown. In FIG. 9a, the correspondence between the lenses is indicated by dotted lines.

[0200] First, referring to FIGS. 3, 4 and 9a, the second pixel PX2 may include a second selection circuit SC2 and a plurality of light emitting elements ED3 and ED4.

[0201] The second selection circuit SC2 may include a third transistor T3 and a fourth transistor T4, which may correspond to the first selection transistor TP1 and the second selection transistor TP2 described with reference to FIGS.

[0202] The gate electrode of the third transistor T3 may be turned on or off in response to a select signal provided from a third select signal line SSL3, and the gate electrode of the fourth transistor T4 may be turned on or off in response to a select signal provided from a fourth select signal line SSL4. Here, the select signal provided from the third select signal line SSL3 and the select signal provided from the fourth select signal line SSL4 may be, but are not limited to, the first select signal Ss and the second select signal Ps described with reference to FIGS. 3 and 4, respectively.

[0203] The plurality of light-emitting elements ED3 and ED4 included in the second pixel PX2 may include a third light-emitting element ED3 and a fourth light-emitting element ED4. The third light-emitting element ED3 of the second pixel PX2 may be connected between the third transistor T3 and a second power supply line providing the second power supply voltage VSS, and the fourth light-emitting element ED4 of the second pixel PX2 may be connected between the fourth transistor T4 and a second power supply line providing the second power supply voltage VSS, as substantially the same as or similar to those described with reference to FIGS. 3 and 4. For example, the third light-emitting element ED3 and the fourth light-emitting element ED4 of FIG. 9a may be light-emitting elements corresponding to the first-type light-emitting element EDa and the second-type light-emitting element EDb described with reference to FIGS. 3 and 4, respectively.

[0204] As a result, when the third transistor T3 is turned on in response to a turn-on level selection signal provided from the third selection signal line SSL3, a first driving current is formed through the third light-emitting element ED3, allowing the third light-emitting element ED3 of the second pixel PX2 to emit light.

[0205] In addition, when the fourth transistor T4 is turned on in response to a turn-on level selection signal provided from the fourth selection signal line SSL4, a second driving current is formed through the fourth light-emitting element ED4, allowing the fourth light-emitting element ED4 of the second pixel PX2 to emit light.

[0206] The second pixel PX2 may be driven in a first state in which the third light-emitting element ED3 emits light, or in a second state in which the fourth light-emitting element ED4 emits light.

[0207] The second pixel PX2 may include a third lens LS3 disposed above the third light-emitting element ED3 and a fourth lens LS4 disposed above the fourth light-emitting element ED4.

[0208] To explain the third lens LS3 and the fourth lens LS4 in more detail, referring further to Figure 9b, the second pixel PX2 may include a third lens area LSA3 and a fourth lens area LSA4 in which the third light-emitting element ED3 and the fourth light-emitting element ED4 are located, respectively.

[0209] The third lens area LSA3 and the fourth lens area LSA4 can provide images through different viewing angles, and the luminance of the third lens area LSA3 can be controlled by a first driving current generated by the third light-emitting element ED3, and the luminance of the fourth lens area LSA4 can be controlled by a second driving current generated by the fourth light-emitting element ED4.

[0210] The third lens LS3 may be located above the third light-emitting element ED3, and the fourth lens LS4 may be located above the fourth light-emitting element ED4.

[0211] The third lens LS3 may have a first shape. The third lens LS3 may have a shape that does not restrict light in at least one direction. For example, the planar shape of the third lens LS3 located in the second pixel PX2 may have a bar shape extending in one direction. As an example, the third lens LS3 may be embodied as the first type lens 161 described with reference to FIG. 6.

[0212] In this case, when the light generated by the third light emitting element ED3 of the second pixel PX2 is emitted through the third lens LS3, the traveling direction of the light is not limited to one direction.

[0213] The fourth lens LS4 may have a second shape. The fourth lens LS4 may limit the direction of travel of light passing through it to one direction and / or another direction. For example, the planar shape of the fourth lens LS4 located in the second pixel PX2 may be circular. As an example, the fourth lens LS4 may be embodied as the second type lens 162 described with reference to FIG. 7.

[0214] In this case, when the light generated by the fourth light emitting element ED4 of the second pixel PX2 is emitted through the fourth lens LS4, the traveling direction of the light may be limited to one direction and / or another direction.

[0215] The third light-emitting area EA3 defined by the third light-emitting element ED3 of the second pixel PX2 may have a shape corresponding to the third lens LS3, and the fourth light-emitting area EA4 defined by the fourth light-emitting element ED4 of the second pixel PX2 may have a shape corresponding to the fourth lens LS4.

[0216] 9b, the third light-emitting region EA3 may have a bar shape extending in one direction to correspond to the shape of the third lens LS3. In this case, the third lens LS3 located on the third lens region LSA3 may be larger than the third light-emitting region EA3 included in the third lens region LSA3. This may improve the efficiency of light emitted from the third light-emitting region EA3 of the second pixel PX2.

[0217] 9b, the planar shape of the fourth light-emitting region EA4 may be circular to correspond to the shape of the fourth lens LS4. In this case, the fourth lens LS4 located in the fourth lens region LSA4 may be larger than the fourth light-emitting region EA4 included in the fourth lens region LSA4. For example, the planar shape of the fourth light-emitting region EA4 located in the fourth lens region LSA4 may be a circle concentric with the planar shape of the fourth lens LS4 located in the fourth lens region LSA4. In this case, the efficiency of light emitted from the fourth light-emitting region EA4 of the second pixel PX2 may be improved.

[0218] Since the third lens LS3 is implemented in the first type lens 161, the third lens area LSA3 may include one third light-emitting area EA3 and one third lens LS3, as described with reference to Fig. 6. Also, since the fourth lens LS4 is implemented in the second type lens 162, the fourth lens area LSA4 may include two fourth light-emitting areas EA4 and two fourth lenses LS4, as described with reference to Fig. 7.

[0219] Therefore, when the first driving current is formed in the second pixel PX2 and the third light-emitting element ED3 emits light, the light generated by the third light-emitting element ED3 of the third pixel PX3 is emitted through the third lens LS3 implemented in the first type lens 161. Therefore, content provided by the light generated by the third light-emitting element ED3 of the second pixel PX2 may be provided at a first viewing angle. For example, the provided content (or image) may be shared with people nearby in one direction from the user. Thus, the content provided by the light emitted through the third lens LS3 may be provided in a wide viewing mode (Share mode).

[0220] Furthermore, when a second driving current is formed in the second pixel PX2 and the fourth light-emitting element ED4 emits light, the light generated by the fourth light-emitting element ED4 of the second pixel PX2 is emitted through the fourth lens LS4 implemented in the second type lens 162. Therefore, content provided by the light generated by the fourth light-emitting element ED4 of the second pixel PX2 may be provided at a second viewing angle. For example, the provided content (or image) does not need to be shared with people around the user. Therefore, the content provided by the light emitted through the fourth lens LS4 may be provided in a narrow viewing mode (private mode).

[0221] As described above, the second pixel PX2 may be driven in a first state in which the third light-emitting element ED3 emits light, or in a second state in which the fourth light-emitting element ED4 emits light. When the second pixel PX2 is driven in the first state, light generated by the third light-emitting element ED3 may provide content at a first viewing angle. When the second pixel PX2 is driven in the second state, light generated by the fourth light-emitting element ED4 may provide content at a second viewing angle.

[0222] In this way, the second region among the multiple regions of the display panel PN, in which the second pixel PX2 driven in the first state or the second state is arranged, can provide wide viewing mode content or narrow viewing mode content depending on the driving mode.

[0223] Fig. 10 is a diagram illustrating an example of a display panel of a display device according to an embodiment of the present specification. Fig. 11 is a plan view schematically illustrating the lens arrangement of a first pixel and a second pixel included in the display panel of Fig. 10.

[0224] On the other hand, Figure 10 shows an example of a display panel PN included in a display device 100 according to one embodiment of this specification described with reference to Figure 2, and including first and second regions A1 and A2, and Figure 11 shows an example of a first pixel PX1 arranged in the first region A1 of the display panel PN of Figure 10 and a second pixel PX2 arranged in the second region A2.

[0225] On the other hand, FIG. 11 shows an example in which the first pixel PX1 and the second pixel PX2 each include three sub-pixels.

[0226] On the other hand, for convenience of explanation, in FIGS. 10 and 11, the horizontal direction on the plane is shown as a first direction DR1, and the vertical direction on the plane is shown as a second direction DR2.

[0227] On the other hand, for ease of explanation, Figure 10 shows a plurality of pixel rows and a plurality of pixel columns in which a plurality of first pixels PX1 are arranged on the first region A1, including a plurality of rows R1, R2 defined as being parallel to the first direction DR1 and a plurality of columns C1 to Cm defined as being parallel to the second direction DR2.

[0228] 2, 6 to 10, the display panel PN may be divided into a plurality of regions A1 and A2. For example, as shown in Fig. 10, the display panel PN may be divided into two regions A1 and A2. For example, the display panel PN may include a first region A1 and a second region A2 adjacent to the first region A1 in the opposite direction of the first direction DR1.

[0229] Each of the regions A1 and A2 included in the display panel PN may include a plurality of pixels, each having a pixel circuit arranged therein. For example, the first region A1 may include a plurality of first pixels PX1 spaced apart from each other along the first direction DR1 and the second direction DR2, and the second region A2 may include a plurality of second pixels PX2 spaced apart from each other along the first direction DR1 and the second direction DR2.

[0230] Meanwhile, as described above, the first area A1 of the display panel PN is an area provided on the driver's seat side located in the front seat of the vehicle as described with reference to FIG. 1, and is an area that provides content in wide viewing mode, and the second area A2 of the display panel PN is an area provided on the passenger's seat side located in the front seat of the vehicle as described with reference to FIG. 1, and may be an area that provides content in wide viewing mode or narrow viewing mode depending on the driving mode of the display device 100.

[0231] For example, the first pixels PX1 arranged in the first region A1 may display an image through the first lens region LSA1 and the second lens region LSA2. As an example, regardless of the driving mode, for example, in each of the first and second modes, the first pixels PX1 arranged in the first region A1 may be driven in a third state in which both the first lens region LSA1 and the second lens region LSA2 display an image.

[0232] 8a and 8b, the first lens LS1 located in the first lens region LSA1 and the second lens LS2 located in the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 can both emit (provide) light at the first viewing angle, so that an image displayed by the plurality of first pixels PX1 arranged in the first region A1 can be provided to a user at the first viewing angle in both the first and second modes.

[0233] The second pixels PX2 arranged in the second area A2 can display an image through the third lens area LSA3 and the fourth lens area LSA4. For example, each of the second pixels PX2 arranged in the second area A2 can be driven in a first state in which only the third lens area LSA3 displays an image in a first mode, or in a second state in which only the fourth lens area LSA4 displays an image in a second mode.

[0234] 9a and 9b, the third lenses LS3 located in the third lens areas LSA3 of the second pixels PX2 arranged in the second region A2 can provide light at a first viewing angle. Therefore, in the first mode, an image displayed by the second pixels PX2 arranged in the second region A2 can be provided to a user at the first viewing angle. Furthermore, the fourth lenses LS4 located in the fourth lens areas LSA4 of the second pixels PX2 arranged in the second region A2 can provide light at a second viewing angle. Therefore, in the second mode, an image displayed by the second pixels PX2 arranged in the second region A2 can be provided to a user at the second viewing angle.

[0235] On the other hand, as mentioned above, if the first pixel PX1 arranged in the first region A1 and the second pixel PX2 arranged in the second region A2 have different lens arrangement structures, a problem may arise in which the boundary between the first region A1 and the second region A2 becomes visible.

[0236] To explain this in more detail, referring further to FIG. 11, the first pixel PX1 includes a first red subpixel RSP1 that represents red, a first green subpixel GSP1 that represents green, and a first blue subpixel BSP1 that represents blue, and the second pixel PX2 includes a second red subpixel RSP2 that represents red, a second green subpixel GSP2 that represents green, and a second blue subpixel BSP2 that represents blue.

[0237] 11 are merely exemplary, and the embodiments of the present specification are not limited thereto. For example, the first pixel PX1 and / or the second pixel PX2 may further include a sub-pixel for implementing a specific color other than red, green, and blue, for example, white.

[0238] The first pixel PX1 and the second pixel PX2 may have substantially the same subpixel arrangement. For example, the first pixel PX1 may have a subpixel arrangement in which the first green subpixel GSP1 and the first blue subpixel BSP1 are arranged side by side in the second direction DR2 on one side of the first red subpixel RSP1 in the first direction DR1. Similarly, the second pixel PX2 may have a subpixel arrangement in which the second green subpixel GSP2 and the second blue subpixel BSP2 are arranged side by side in the second direction DR2 on one side of the second red subpixel RSP2 in the first direction DR1. However, this is merely an example, and the subpixel arrangements of the first pixel PX1 and / or the second pixel PX2 are not limited thereto. The first pixel PX1 and the second pixel PX2 may have a subpixel arrangement different from the arrangement shown in FIG. 11 and / or the first pixel PX1 and the second pixel PX2 may have subpixel arrangements different from each other.

[0239] The first pixel PX1 may include a plurality of first lens areas LSA1 in which the first lenses LS1 are disposed for each sub-pixel, and a plurality of second lens areas LSA2 in which the second lenses LS2 are disposed for each sub-pixel.

[0240] For example, the first red subpixel RSP1 of the first pixel PX1 includes a first sub-lens area LSA1a where the first lens LS1 is arranged and a second sub-lens area LSA2a where the second lens LS2 is arranged, the first green subpixel GSP1 of the first pixel PX1 includes a third sub-lens area LSA1b where the first lens LS1 is arranged and a fourth sub-lens area LSA2b where the second lens LS2 is arranged, and the first blue sub-pixel BSP1 of the first pixel PX1 includes a fifth sub-lens area LSA1c where the first lens LS1 is arranged and a sixth sub-lens area LSA2c where the second lens LS2 is arranged.

[0241] Here, the first sub-lens area LSA1a, the third sub-lens area LSA1b, and the fifth sub-lens area LSA1c in which the first lens LS1 of the first pixel PX1 is arranged may be areas included in the first lens area LSA1. That is, the first lens LS1 having a first shape is arranged on the first sub-lens area LSA1a, the third sub-lens area LSA1b, and the fifth sub-lens area LSA1c of the first pixel PX1, respectively, so that an image displayed from the first sub-lens area LSA1a, the third sub-lens area LSA1b, and the fifth sub-lens area LSA1c of the first pixel PX1 may be provided to a user at a first viewing angle.

[0242] Furthermore, the second sub-lens region LSA2a, the fourth sub-lens region LSA2b, and the sixth sub-lens region LSA2c in which the second lens LS2 of the first pixel PX1 is arranged may be regions included in the second lens region LSA2. That is, since the second lens LS2 having the first shape is arranged on the second sub-lens region LSA2a, the fourth sub-lens region LSA2b, and the sixth sub-lens region LSA2c of the first pixel PX1, an image displayed from the second sub-lens region LSA2a, the fourth sub-lens region LSA2b, and the sixth sub-lens region LSA2c of the first pixel PX1 may be provided to the user at a first viewing angle.

[0243] That is, the first to sixth sub-lens areas LSA1a, LSA2a, LSA1b, LSA2b, LSA3a, and LSA3b of the first pixel PX1 can provide images at the same viewing angle.

[0244] The second pixel PX2 may include a plurality of third lens areas LSA3 in which the third lenses LS3 are disposed for each sub-pixel, and a plurality of fourth lens areas LSA4 in which the fourth lenses LS4 are disposed for each sub-pixel.

[0245] For example, the second red subpixel RSP2 of the second pixel PX2 includes a seventh sub-lens region LSA3a where the third lens LS3 is arranged and an eighth sub-lens region LSA4a where the fourth lens LS4 is arranged, the second green subpixel GSP2 of the second pixel PX2 includes a ninth sub-lens region LSA3b where the third lens LS3 is arranged and a tenth sub-lens region LSA4b where the fourth lens LS4 is arranged, and the second blue sub-pixel BSP2 of the second pixel PX2 includes an eleventh sub-lens region LSA3c where the third lens LS3 is arranged and a twelfth sub-lens region LSA4c where the fourth lens LS4 is arranged.

[0246] Here, the seventh sub-lens region LSA3a, the ninth sub-lens region LSA3b, and the eleventh sub-lens region LSA3c in which the third lens LS3 of the second pixel PX2 is arranged may be regions included in the third lens region LSA3. That is, since the third lens LS3 having the first shape is arranged on the seventh sub-lens region LSA3a, the ninth sub-lens region LSA3b, and the eleventh sub-lens region LSA3c of the second pixel PX2, an image displayed through the seventh sub-lens region LSA3a, the ninth sub-lens region LSA3b, and the eleventh sub-lens region LSA3c of the second pixel PX2 may be provided to a user at a first viewing angle.

[0247] Furthermore, the eighth sub-lens region LSA4a, the tenth sub-lens region LSA4b, and the twelfth sub-lens region LSA4c in which the fourth lens LS4 of the second pixel PX2 is arranged may be regions included in the fourth lens region LSA4. That is, since the fourth lens LS4 having the second shape is arranged on the eighth sub-lens region LSA4a, the tenth sub-lens region LSA4b, and the twelfth sub-lens region LSA4c of the second pixel PX2, an image displayed through the eighth sub-lens region LSA4a, the tenth sub-lens region LSA4b, and the twelfth sub-lens region LSA4c of the second pixel PX2 may be provided to the user at the second viewing angle.

[0248] That is, the seventh sub-lens area LSA3a, the ninth sub-lens area LSA3b, and the eleventh sub-lens area LSA3c in which the third lens LS3 of the second pixel PX2 is arranged, and the eighth sub-lens area LSA4a, the tenth sub-lens area LSA4b, and the twelfth sub-lens area LSA4c in which the fourth lens LS4 is arranged can provide images at different viewing angles.

[0249] The arrangement of the first lens area LSA1 and the second lens area LSA2 of the first pixel PX1 may be substantially the same as the arrangement of the third lens area LSA3 and the fourth lens area LSA4 of the second pixel PX2.

[0250] For example, the third lens area LSA3 in which the third lens LS3 of the first type lens 161 is arranged on the second pixel PX2, for example, the first lens area LSA1 of the first pixel PX1, for example, the first sub-lens area LSA1a, the third sub-lens area LSA1b and the fifth sub-lens area LSA1c, may be arranged at positions corresponding to the seventh sub-lens area LSA3a, the ninth sub-lens area LSA3b and the eleventh sub-lens area LSA3c, respectively.

[0251] Furthermore, the second lens area LSA2 of the first pixel PX1, for example, the second sub-lens area LSA2a, the fourth sub-lens area LSA2b, and the sixth sub-lens area LSA2c, may be arranged at positions corresponding to the fourth lens area LSA4 where the fourth lens LS4 of the second type lens 162 is arranged on the second pixel PX2, for example, the eighth sub-lens area LSA4a, the tenth sub-lens area LSA4b, and the twelfth sub-lens area LSA4c, respectively.

[0252] The number of fourth lenses LS4 arranged in the fourth lens region LSA4 and the number of corresponding light-emitting areas may vary for each of the subpixels RSP2, GSP2, and BSP2 of the second pixel PX2. For example, the number of fourth lenses LS4 arranged in the tenth sub-lens region LSA4b of the second green subpixel GSP2 and the number of fourth lenses LS4 arranged in the twelfth sub-lens region LSA4c of the second blue subpixel BSP2 may be greater than the number of fourth lenses LS4 arranged in the eighth sub-lens region LSA4a of the second red subpixel RSP2. In this case, the efficiency deviation of the fourth light-emitting element ED4 arranged in the fourth lens region LSA4 of the second pixel PX2 may be compensated for by the number of fourth lenses LS4 arranged in the fourth lens region LSA4 of each second pixel PX2 and the number of corresponding light-emitting areas. However, the number of fourth lenses LS4 arranged on the fourth lens area LSA4 for each of the sub-pixels RSP2, GSP2, and BSP2 of the second pixel PX2 and the number of corresponding light-emitting areas are not limited to this, and depending on the embodiment, the number of fourth lenses LS4 arranged on the fourth lens area LSA4 for each of the sub-pixels RSP2, GSP2, and BSP2 of the second pixel PX2 and the number of corresponding light-emitting areas may be the same.

[0253] In this way, the first pixel PX1 arranged in the first region A1 and the second pixel PX2 arranged in the second region A2 may have different lens arrangement structures. For example, in the case of the first pixel PX1, lenses having a first shape, such as a first lens LS1 and a second lens LS2, may be arranged in all of the lens regions LSA1 and LSA2, whereas in the case of the second pixel PX2, a third lens LS3 having the first shape may be arranged in the third lens region LSA3, and a fourth lens LS4 having a second shape may be arranged in the fourth lens region LSA4.

[0254] As a result, if the multiple first pixels PX1 arranged in the first region A1 and the multiple second pixels PX2 arranged in the second region A2 display an image at the same brightness, the difference in lens arrangement structure between the first pixels PX1 and the second pixels PX2 may cause a problem in which the boundary between the first region A1 and the second region A2 is visible.

[0255] In particular, when the display device 100 is driven in the first mode, as described above, the plurality of first pixels PX1 in the first region A1 are driven in the third state to display an image through the first lens region LSA1 and the second lens region LSA2, while the plurality of second pixels PX2 in the second region A2 are driven in the first state to display an image only through the third lens region LSA3. Here, in the first mode, the first region A1 and the second region A2 all provide an image to the user at the same first viewing angle, so that the image displayed in the first region A1 and the image displayed in the second region A2 may be provided to the user in a form in which they are continuously arranged. In this case, if the first pixels PX1 arranged in the first region A1 and the second pixels PX2 arranged in the second region A2 display an image at the same brightness, the first pixels PX1 in the first region A1 are driven in the third state to display an image through the first lens region LSA1 and the second lens region LSA2, and therefore the brightness of the first region A1 may be higher than that of the second region A2, which is driven in the first state to display an image only through the third lens region LSA3. This brightness difference may cause a problem in which the boundary between the first region A1 and the second region A2 is visible.

[0256] To solve this problem, the display device 100 according to an embodiment of the present specification can control the brightness of the display panel PN according to the driving mode of the display device 100 based on the mode signal MODE. For example, as described with reference to Fig. 2, the brightness controller LD generates corrected image data CDATA for controlling the brightness of the display panel PN according to the driving mode of the display device 100 based on the mode signal MODE, and the timing controller TD generates image data RGB to be provided to the data driving circuit DD based on the corrected image data CDATA, thereby controlling the brightness of the image displayed on the display panel PN.

[0257] The display device 100, for example, the luminance controller LD, may control the luminance of the display panel PN, for example, the first region A1, so that the luminance of the first region A1 increases with increasing distance from the boundary between the first region A1 and the second region A2. The luminance controller LD may also control the luminance of a region in the first region A1 adjacent to the boundary between the first region A1 and the second region A2 to have a value substantially equal to or similar to the luminance of the second region A2. In a first mode in which an image is provided at a first viewing angle in both the first region A1 and the second region A2, such driving of the luminance controller LD may minimize the luminance difference between the first region A1 and the second region A2 at the boundary between the first region A1 and the second region A2, thereby improving the visibility of the boundary between the first region A1 and the second region A2.

[0258] 12 to 18, a configuration in which the display device 100, for example, the brightness controller LD controls the brightness of the first region A1 will be described in more detail. Meanwhile, as described above, the brightness controller LD can control the brightness of the first region A1 by generating corrected video data CDATA based on the input video data IDATA, but the configuration in which the brightness controller LD controls the brightness of the first region A1 is not limited to this.

[0259] Fig. 12 is a diagram illustrating an example in which a display device according to an embodiment of the present specification is driven in a first mode. Fig. 13 is a diagram illustrating an example in which a display device according to an embodiment of the present specification is driven in a second mode.

[0260] On the other hand, FIGS. 12 and 13 show examples of the display panel PN when the display device 100 according to an embodiment of the present specification is driven in the first mode and the second mode, respectively.

[0261] On the other hand, for convenience of explanation, in FIGS. 12 and 13, when a light emitting element arranged in a lens area on the display panel PN does not emit light, it is indicated as "Off."

[0262] 2 to 11, a mode controller MS included in the display device 100 can generate a mode selection signal MSS based on a mode signal MODE input from an external device. For example, the mode controller MS can receive a mode signal MODE from an external device corresponding to a driving mode of the display device 100, generate a mode selection signal MSS based on the mode signal MODE, and provide the generated mode selection signal to the mode selection unit MD. In addition, the mode selection unit MD can provide a selection signal corresponding to the driving mode to a plurality of pixels PX, for example, a plurality of first pixels PX1 arranged in the first region A1 and a plurality of second pixels PX2 arranged in the second region A2, in response to the mode selection signal MSS provided from the mode controller MS.

[0263] When the display device 100 is driven in the first mode, the second area A2 of the display panel PN can provide content with a first viewing angle to the user in response to a selection signal provided from the mode selection unit MD.

[0264] Specifically, referring again to FIG. 12, in the first mode, each of the plurality of second pixels PX2 arranged on the second region A2 may be driven in a first state.

[0265] For example, in the first mode, the third transistor T3 included in the second pixel PX2 is turned on in response to a selection signal provided through the third selection signal line SSL3, thereby forming a first driving current within the second pixel PX2, and the light generated by the third light-emitting element ED3 arranged on the third lens area LSA3 of the second pixel PX2 emitting light due to the first driving current is emitted through the third lens LS3 arranged on the third lens area LSA3 and composed of a first type lens 161, thereby providing content at a first viewing angle.

[0266] Meanwhile, since a selection signal maintained at a turn-off level is provided to the fourth selection signal line SSL4 in the first mode, the fourth transistor T4 included in the second pixel PX2 is maintained in a turn-off state, and the fourth light-emitting element ED4 disposed on the fourth lens area LSA4 of the second pixel PX2 is maintained in a non-emitting state. That is, a current path for the second driving current does not need to be formed within the second pixel PX2 in the second mode.

[0267] Furthermore, when the display device 100 is driven in the second mode, the second area A2 of the display panel PN can provide content with a second viewing angle to the user in response to a selection signal provided from the mode selection unit MD.

[0268] Specifically, referring again to FIG. 13, in the second mode, each of the plurality of second pixels PX2 arranged on the second region A2 may be driven in the second state.

[0269] For example, in the second mode, the fourth transistor T4 included in the second pixel PX2 is turned on in response to a selection signal provided through the fourth selection signal line SSL4, thereby forming a second driving current within the second pixel PX2, and the light generated by the fourth light-emitting element ED4 arranged on the fourth lens area LSA4 of the second pixel PX2 emitting light due to the second driving current is emitted through the fourth lens LS4 arranged on the fourth lens area LSA4 and composed of the second type lens 162, thereby providing content of a second viewing angle.

[0270] Meanwhile, in the second mode, a selection signal maintained at a turn-off level is provided to the third selection signal line SSL3, so that the third transistor T3 included in the second pixel PX2 is maintained in a turn-off state, and the third light-emitting element ED3 of the second pixel PX2 is maintained in a non-emitting state, i.e., a current path for the first driving current is not formed within the second pixel PX2 in the second mode.

[0271] As a result, when the display device 100 is driven in the first mode, content with a first viewing angle can be provided to the user on the second region A2 of the display panel PN, and when the display device 100 is driven in the second mode, content with a second viewing angle can be provided to the user on the second region A2 of the display panel PN.

[0272] The display device 100 can control the luminance of the second region A2 to correspond to the input image data IDATA regardless of the driving mode. For example, the luminance controller LD can generate the corrected image data CDATA corresponding to the second region A2 so that the value of the corrected image data CDATA is the same as the value of the input image data IDATA.

[0273] As a result, in a first mode in which content is provided to a user at a first viewing angle and a second mode in which content is provided to a user at a second viewing angle, the second pixels PX2 arranged on the second area A2 can display an image at a luminance (hereinafter referred to as "reference luminance L0") corresponding to the input image data IDATA. For example, as shown in FIG. 12, the third lens area LSA3 of each of the plurality of second pixels PX2 can emit light at the reference luminance L0 in the first mode, and as shown in FIG. 13, the fourth lens area LSA4 of each of the plurality of second pixels PX2 can emit light at the reference luminance L0 in the second mode.

[0274] Also, as described above, in the first mode in which wide viewing mode content is provided and the second mode in which narrow viewing mode content is provided, all of the display panels PN can be driven to provide content with a first viewing angle on the first region A1.

[0275] For example, when the display device 100 is driven in either the first mode or the second mode, in response to a selection signal provided from the mode selection unit MD, the first area A1 of the display panel PN can provide content at a first viewing angle to the user.

[0276] Specifically, referring to FIGS. 12 and 13, in the first mode and the second mode, each of the plurality of first pixels PX1 arranged on the first region A1 may be driven in the third state.

[0277] For example, in each of the first and second modes, a first transistor T1 included in the first pixel PX1 may be turned on in response to a selection signal provided through a first selection signal line SSL1 to form a first driving current in the first pixel PX1, and a second transistor T2 included in the first pixel PX1 may be turned on in response to a selection signal provided through a second selection signal line SSL2 to form a second driving current in the first pixel PX1. Furthermore, light generated by a first light-emitting element ED1 disposed on a first lens region LSA1 of the first pixel PX1 is emitted in response to the first driving current and is then emitted through a first lens LS1 disposed on the first lens region LSA1 and configured with a first-type lens 161, and light generated by a second light-emitting element ED2 disposed on a second lens region LSA2 of the first pixel PX1 is emitted in response to the second driving current and is then emitted through a second lens LS2 disposed on a second lens region LSA2 and configured with a first-type lens 161, thereby providing content at a first viewing angle.

[0278] The display device 100 may control the display panel PN, for example, the luminance of the first region A1, such that the luminance of the first region A1 increases with increasing distance from the boundary between the first region A1 and the second region A2 in the first mode. For example, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first region A1 to increase with increasing distance from the boundary between the first region A1 and the second region A2 in the first mode.

[0279] In addition, the display device 100 can control the brightness of the area in the first region A1 adjacent to the boundary between the first region A1 and the second region A2 to have a value that is substantially the same as or similar to the brightness of the second region A2.

[0280] 12, in the first mode, the display device 100 may control the luminance of the first lens area LSA1 of the first pixel PX1 arranged on the first region A1 to correspond to the input image data IDATA. For example, the luminance controller LD may generate corrected image data CDATA such that the value of the corrected image data CDATA corresponding to the first lens area LSA1 of each of the plurality of first pixels PX1 arranged on the first region A1 is equal to the value of the input image data IDATA. As a result, in the first mode, the first lens area LSA1 of the first pixel PX1 arranged on the first region A1 may emit light at the reference luminance L0.

[0281] In addition, in the first mode, the luminance of the second lens area LSA2 of the first pixel PX1 disposed on the first area A1 may increase as it moves away from the boundary between the first area A1 and the second area A2.

[0282] For example, the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first area A1 and the second area A2 on the first area A1 can emit light at a first brightness L1 lower than the reference brightness L0.

[0283] In addition, the second lens areas LSA2 of the first pixels PX1 arranged on the second column C2 adjacent to the first column C1 in the first direction DR1 in the first area A1 may emit light at a second luminance L2 higher than the first luminance L1, where the second luminance L2 may be lower than the reference luminance L0.

[0284] Similarly, the second lens regions LSA2 of the first pixels PX1 arranged on a third column C3 adjacent to the second column C2 in the first direction DR1 in the first region A1 may emit light at a third luminance L3 higher than the second luminance L2, where the third luminance L3 may be lower than the reference luminance L0.

[0285] Similarly, the second lens regions LSA2 of the first pixels PX1 arranged on a fourth column C4 adjacent to the third column C3 in the first direction DR1 in the first region A1 may emit light at a fourth luminance L4 higher than the third luminance L3, where the fourth luminance L4 may be lower than the reference luminance L0.

[0286] Similarly, the second lens regions LSA2 of the first pixels PX1 arranged on the m-1-th column Cm-1 adjacent to the m-th column Cm (where m is an integer greater than 0) in the first region A1, which is farthest from the boundary between the first region A1 and the second region A2, along the opposite direction of the first direction DR1, may emit light at a fifth luminance L5 higher than the fourth luminance L4, where the fifth luminance L5 may be lower than the reference luminance L0.

[0287] Furthermore, the second lens regions LSA2 of the first pixels PX1 arranged on the m-th column Cm in the first region A1, which is the farthest from the boundary between the first region A1 and the second region A2, can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of the second lens regions LSA2 of the first pixels PX1 arranged on the pixel column farthest from the boundary between the first region A1 and the second region A2, for example, the m-th column Cm, among the first pixels PX1 arranged on the first region A1, so that the luminance corresponds to the input image data IDATA.

[0288] In this way, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 to increase as the pixel moves away from the boundary between the first region A1 and the second region A2, for example, in the first direction DR1. For example, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 to increase as the pixel moves from the first column C1 to the m-th column Cm. This may minimize the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode.

[0289] The first luminance L1 of each of the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 may have a luminance corresponding to a substantially black image. For example, the first luminance L1 may have a value of 0. In this case, the luminance of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 corresponds to a value obtained by adding the reference luminance L0 of the first lens region LSA1 and the first luminance L1 of the second lens region LSA2. Therefore, the luminance of each of the plurality of first pixels PX1 arranged on the first column C1 may have a value substantially equal to or similar to the reference luminance L0.

[0290] As a result, the luminance of each of the plurality of first pixels PX1 arranged in the first column C1 closest to the boundary between the first region A1 and the second region A2 in the first region A1 may be substantially the same as or similar to the luminance of each of the plurality of second pixels PX2 arranged in the second region A2, e.g., the reference luminance L0, thereby more effectively alleviating the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode.

[0291] However, the embodiments of this specification are not limited to this, and the second lens area LSA2 of each of the multiple first pixels PX1 arranged on the first column C1 closest to the boundary between the first area A1 and the second area A2 on the first area A1 may be non-emitting.

[0292] 11 , the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 may be arranged at a position in the lens arrangement structure corresponding to the fourth lens area LSA4 in which the fourth lens LS4 of the second-type lens 162 is arranged in the plurality of second pixels PX2 arranged in the second region A2. As a result, when the display device 100 controls the luminance of the plurality of first pixels PX1 arranged in the first region A1 to increase as the display device 100 moves away from the boundary between the first region A1 and the second region A2, for example, in the first direction DR1, the problem of the boundary between the first region A1 and the second region A2 being visible may be more effectively alleviated by controlling the luminance of the second lens area LSA2 of the first pixel PX1 that corresponds in the lens arrangement structure to the fourth lens area LSA4 in the second region A2 that is non-emitting in the first mode.

[0293] In the first mode, the display device 100 may control the luminance of the second lens area LSA2 of each of the first pixels PX1 arranged in the first area A1 to linearly increase as the luminance increases from the boundary between the first area A1 and the second area A2, for example, in the first direction DR1, thereby minimizing the problem of a luminance change in the first area A1, for example, a luminance change in the first direction DR1, being visible to the user.

[0294] Meanwhile, as described above, the display device 100 can control the luminance of the first area A1 in the second mode so that it corresponds to the input image data IDATA.

[0295] 13, in the second mode, the display device 100 may control the luminance of the first lens area LSA1 and the luminance of the second lens area LSA2 of the first pixel PX1 arranged on the first region A1 so that they correspond to the input image data IDATA. For example, the luminance controller LD may generate corrected image data CDATA such that the value of the corrected image data CDATA corresponding to the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the first region A1 is equal to the value of the input image data IDATA. Thus, in the second mode, the first lens area LSA1 of the first pixel PX1 arranged on the first region A1 may emit light at the reference luminance L0, and the second lens area LSA2 of the first pixel PX1 arranged on the first region A1 may emit light at the reference luminance L0.

[0296] Meanwhile, in this second mode, the first lens area LSA1 and the second lens area LSA2 of the first pixel PX1 arranged on the first area A1 all emit light at the reference luminance L0, which may cause a luminance difference between the image displayed on the first area A1 and the image displayed on the second area A2. However, despite this luminance difference, in the second mode, the image is displayed on the first area A1 at the first viewing angle and the image is displayed on the second area A2 at the second viewing angle, so the problem of a boundary being substantially visible to the user does not occur.

[0297] As described above, the display device 100 according to an embodiment of the present disclosure may display content at a first viewing angle on the display panel PN in a first mode depending on the driving mode, and may display content at a second viewing angle on at least a portion (second region) of the display panel PN in a second mode depending on the driving mode. Here, the display device 100 according to an embodiment of the present disclosure may control the luminance of the first region A1 of the display panel PN such that the luminance of the first region A1 increases with increasing distance from the boundary between the first region A1 and the second region A2, which provide content at the first viewing angle in the first mode depending on the driving mode. In addition, the display device 100 may control the luminance of a region of the first region A1 adjacent to the boundary between the first region A1 and the second region A2 to have a value substantially the same as or similar to the luminance of the second region A2.

[0298] This can alleviate the problem of the boundary between the first area A1 and the second area A2 being visible.

[0299] On the other hand, the above description has been based on the display device 100 controlling the brightness of the second lens area LSA2 of each of the multiple first pixels PX1 arranged on the first area A1 in the first mode, and controlling the brightness of the multiple first pixels PX1 arranged throughout the first area A1, but the examples in this specification are not limited to this.

[0300] Therefore, various embodiments of the present specification in which the display device 100 controls the luminance of the first area A1 in the first mode will be described in more detail below.

[0301] FIG. 14 is a diagram illustrating another example in which the display device according to an embodiment of the present specification is driven in the first mode.

[0302] FIG. 14 shows an example in which the display device 100 controls the brightness of a part of the first area A1, for example, the third area A3, in the first mode.

[0303] On the other hand, FIG. 14 shows an example of the display panel PN when the display device 100 according to an embodiment of the present specification is driven in the first mode.

[0304] 14, the display device 100 may control the luminance of the display panel PN, e.g., the first region A1, such that the luminance of a portion of the first region A1, e.g., the third region A3, increases with increasing distance from the boundary between the first region A1 and the second region A2 in the first mode. For example, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 disposed in the third region A3 adjacent to the second region A2 in the first region A1, such that the luminance of the second lens region LSA2 increases with increasing distance from the boundary between the first region A1 and the second region A2 in the third region A3 in the first mode.

[0305] In addition, the display device 100 can control the brightness of the area of ​​the third area A3 adjacent to the boundary between the first area A1 and the second area A2 to have a value that is substantially the same as or similar to the brightness of the second area A2.

[0306] As a result, in the first mode, the brightness of the first pixel PX1 arranged on the third region A3 of the first region A1 adjacent to the second region A2 has substantially the same value as the brightness of the second region A2 at the part closest to the second region A2, and can increase as it moves away from the boundary between the first region A1 and the second region A2.

[0307] For example, the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first area A1 and the second area A2 on the third area A3 can emit light at a sixth brightness L6 lower than the reference brightness L0.

[0308] Additionally, the second lens regions LSA2 of the first pixels PX1 arranged on the second column C2 adjacent to the first column C1 in the first direction DR1 in the third area A3 may emit light at a seventh luminance L7 higher than the sixth luminance L6, where the seventh luminance L7 may be lower than the reference luminance L0.

[0309] Similarly, the second lens regions LSA2 of the first pixels PX1 arranged on the third column C3 adjacent to the second column C2 in the first direction DR1 in the third region A3 may emit light at an eighth luminance L8 higher than the seventh luminance L7, where the eighth luminance L8 may be lower than the reference luminance L0.

[0310] Furthermore, the second lens areas LSA2 of the plurality of first pixels PX1 arranged in the remaining area of ​​the first region A1 excluding the third region A3, for example, the fourth region A4, can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of the second lens areas LSA2 of the plurality of first pixels PX1 arranged in the remaining area of ​​the first region A1 excluding the third region A3, for example, the fourth region A4, so that the luminance corresponds to the input image data IDATA.

[0311] In this way, in the first mode, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 disposed in the third region A3 adjacent to the second region A2 of the first region A1 to increase as the pixel moves away from the boundary between the first region A1 and the second region A2, for example, in the first direction DR1. For example, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 disposed in the third region A3 to increase as the pixel moves from the first column C1 to the third column C3. This may minimize the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode.

[0312] 12, the sixth luminance L6 of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 in the third region A3 may have a luminance corresponding to a substantially black image. For example, the sixth luminance L6 may have a value of 0. This may more effectively alleviate the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode. However, the embodiments of the present specification are not limited thereto, and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 in the third region A3 may be non-emitting.

[0313] 12, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 disposed in the third region A3 to linearly increase as the luminance increases from the boundary between the first region A1 and the second region A2, for example, in the first direction DR1, in the first mode, thereby minimizing the problem of a change in luminance in the third region A3, for example, a change in luminance in the first direction DR1, being visible to the user.

[0314] 14, the third region A3 of the first region A1 adjacent to the second region A2 includes three pixel columns, i.e., first to third columns C1, C2, and C3. However, this is merely an example for the convenience of explanation, and the embodiments of the present specification are not limited thereto. For example, the third region A3 may be designed to include two or fewer pixel columns, or four or more pixel columns.

[0315] FIG. 15 is a diagram illustrating another example in which the display device according to an embodiment of the present specification is driven in the first mode.

[0316] FIG. 15 shows an example in which the display device 100 controls the luminance of each of the first lens area LSA1 and the second lens area LSA2 of the first pixel PX1 arranged on the first area A1 in the first mode.

[0317] On the other hand, FIG. 15 shows an example of the display panel PN when the display device 100 according to an embodiment of the present specification is driven in the first mode.

[0318] 15, the display device 100 may control the display panel PN, for example, the luminance of the first region A1, in the first mode such that the luminance of the first region A1 increases with increasing distance from the boundary between the first region A1 and the second region A2. For example, the display device 100 may control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first region A1 to increase with increasing distance from the boundary between the first region A1 and the second region A2.

[0319] In addition, the display device 100 can control the brightness of the area in the first region A1 adjacent to the boundary between the first region A1 and the second region A2 to have a value that is substantially the same as or similar to the brightness of the second region A2.

[0320] As a result, in the first mode, the brightness of the first pixel PX1 arranged on the first region A1 has substantially the same value as the brightness of the second region A2 at the part closest to the second region A2, and can increase as it moves away from the boundary between the first region A1 and the second region A2.

[0321] For example, the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first area A1 and the second area A2 on the first area A1 can emit light at a ninth brightness L9 lower than the reference brightness L0.

[0322] In addition, the first lens region LSA1 and the second lens region LSA2 of each of the first pixels PX1 arranged on the second column C2 adjacent to the first column C1 in the first direction DR1 in the first region A1 may emit light at a tenth luminance L10 higher than the ninth luminance L9, where the tenth luminance L10 may be lower than the reference luminance L0.

[0323] Similarly, the first lens region LSA1 and the second lens region LSA2 of each of the first pixels PX1 arranged on the third column C3 adjacent to the second column C2 in the first direction DR1 in the first region A1 may emit light at an eleventh luminance L11 higher than the tenth luminance L10. Here, the eleventh luminance L11 may be lower than the reference luminance L0.

[0324] Similarly, the first lens area LSA1 and the second lens area LSA2 of each of the first pixels PX1 arranged on the fourth column C4 adjacent to the third column C3 in the first direction DR1 in the first area A1 may emit light at a twelfth luminance L12 higher than the eleventh luminance L11, where the twelfth luminance L12 may be lower than the reference luminance L0.

[0325] Similarly, the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the m-1-th column Cm-1 adjacent to the m-th column Cm in the first region A1, which is farthest from the boundary between the first region A1 and the second region A2, along the opposite direction of the first direction DR1, may emit light at a thirteenth luminance L13 higher than the twelfth luminance L12. Here, the thirteenth luminance L13 may be lower than the reference luminance L0.

[0326] Furthermore, the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the m-th column Cm on the first region A1 that is the farthest from the boundary between the first region A1 and the second region A2 can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the pixel column (m-th column Cm) that is the farthest from the boundary between the first region A1 and the second region A2 among the plurality of first pixels PX1 arranged on the first region A1 to correspond to the input image data IDATA.

[0327] In this way, in the first mode, the display device 100 may control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 to increase as the pixel size increases from the boundary between the first region A1 and the second region A2, for example, in the first direction DR1. For example, the display device 100 may control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 to increase as the pixel size increases from the first column C1 to the m-th column Cm. This may minimize the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode.

[0328] The luminance of the first lens region LSA1 and the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 may have a luminance corresponding to half of the reference luminance L0. In this case, the luminance of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 corresponds to the sum of the ninth luminance L9 of the first lens region LSA1, for example, a value corresponding to half the reference luminance L0, and the ninth luminance L9 of the second lens region LSA2, for example, a value corresponding to half the reference luminance L0, so the luminance of each of the plurality of first pixels PX1 arranged on the first column C1 may have a value substantially identical to or similar to the reference luminance L0.

[0329] As a result, the luminance of each of the plurality of first pixels PX1 arranged in the first column C1 closest to the boundary between the first region A1 and the second region A2 in the first region A1 may be substantially the same as or similar to the luminance of each of the plurality of second pixels PX2 arranged in the second region A2, e.g., the reference luminance L0, thereby more effectively alleviating the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode.

[0330] 12, the display device 100 may control the luminance of the first lens region LSA1 and the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 to linearly increase as the distance from the boundary between the first region A1 and the second region A2 increases, for example, as the distance increases in the first direction DR1, thereby minimizing the problem of a change in luminance in the first region A1, for example, a change in luminance in the first direction DR1, being visible to the user.

[0331] FIG. 16 is a diagram illustrating another example in which the display device according to an embodiment of the present specification is driven in the first mode.

[0332] FIG. 16 shows an example in which the display device 100 controls the brightness of a part of the first region A1, for example, the first lens region LSA1 and the second lens region LSA2 of the first pixel PX1 arranged on the third region A3, in the first mode.

[0333] On the other hand, FIG. 16 shows an example of the display panel PN when the display device 100 according to an embodiment of the present specification is driven in the first mode.

[0334] 16, in the first mode, the display device 100 may control the luminance of the display panel PN, e.g., the first region A1, such that the luminance of a portion of the first region A1, e.g., the third region A3, increases with increasing distance from the boundary between the first region A1 and the second region A2. For example, in the first mode, the display device 100 may control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 disposed in the third region A3 adjacent to the second region A2 of the first region A1 to increase with increasing distance from the boundary between the first region A1 and the second region A2.

[0335] In addition, the display device 100 can control the brightness of the area of ​​the third area A3 adjacent to the boundary between the first area A1 and the second area A2 to have a value that is substantially the same as or similar to the brightness of the second area A2.

[0336] As a result, in the first mode, the brightness of the first pixel PX1 arranged on the third region A3 of the first region A1 adjacent to the second region A2 has substantially the same value as the brightness of the second region A2 at the part closest to the second region A2, and can increase as it moves away from the boundary between the first region A1 and the second region A2.

[0337] For example, each of the first lens areas LSA1 and second lens areas LSA2 of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first area A1 and the second area A2 on the third area A3 can emit light at a 14th brightness L14 lower than the reference brightness L0.

[0338] In addition, the first lens regions LSA1 and second lens regions LSA2 of each of the first pixels PX1 arranged on the second column C2 adjacent to the first column C1 in the first direction DR1 in the third area A3 may emit light at a fifteenth luminance L15 higher than the fourteenth luminance L14. Here, the fifteenth luminance L15 may be lower than the reference luminance L0.

[0339] Similarly, the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the third column C3 adjacent to the second column C2 in the first direction DR1 in the third region A3 may emit light at a 16th luminance L16 higher than the 15th luminance L15, where the 16th luminance L16 may be lower than the reference luminance L0.

[0340] Furthermore, the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the remaining area of ​​the first region A1 excluding the third region A3 can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the remaining area of ​​the first region A1 excluding the third region A3, for example, the fourth region A4, so that the luminance corresponds to the input image data IDATA.

[0341] In this way, in the first mode, the display device 100 may control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 disposed in the third region A3 adjacent to the second region A2 of the first region A1 to increase as the distance from the boundary between the first region A1 and the second region A2 increases, for example, toward the first direction DR1. For example, the display device 100 may control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 disposed in the third region A3 to increase as the distance from the first column C1 to the third column C3 increases. This may minimize the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode.

[0342] 15, the fourteenth luminance L14 of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 in the third region A3 may have a luminance substantially corresponding to half the reference luminance L0. This may more effectively alleviate the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode.

[0343] 12, the display device 100 may control the luminance of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the third area A3 to linearly increase as the luminance increases from the boundary between the first area A1 and the second area A2, for example, in the first direction DR1, in the first mode, thereby minimizing the problem of a luminance change in the third area A3, for example, a luminance change in the first direction DR1, being visible to the user.

[0344] 16, the third region A3 of the first region A1 adjacent to the second region A2 includes three pixel columns, i.e., first to third columns C1, C2, and C3. However, this is merely an example for the convenience of explanation, and the embodiments of the present specification are not limited thereto. For example, the third region A3 may be designed to include two or fewer pixel columns, or four or more pixel columns.

[0345] FIG. 17 is a diagram illustrating another example in which the display device according to an embodiment of the present specification is driven in the first mode.

[0346] FIG. 17 shows an example in which the display device 100 controls the luminance of the second lens areas LSA2 of the first pixels PX1 arranged on the first area A1 alternately in pixel row units in the first mode.

[0347] On the other hand, FIG. 17 shows an example of the display panel PN when the display device 100 according to an embodiment of the present specification is driven in the first mode.

[0348] Referring to FIG. 17, in the first mode, the display device 100 can control the brightness of the display panel PN so that the brightness of the first region A1 increases as it moves away from the boundary between the first region A1 and the second region A2.

[0349] In the first mode, the display device 100 can be controlled so that the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 increases in pixel row units as it moves away from the boundary between the first area A1 and the second area A2.

[0350] For example, in the first mode, the display device 100 can be controlled so that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in odd-numbered columns, for example, the first column C1 and the third column C3, increases as the distance from the boundary between the first area A1 and the second area A2 increases.

[0351] In addition, in the first mode, the display device 100 can control the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in the even-numbered rows, for example, the second row R2, among the plurality of first pixels PX1 arranged on the even-numbered columns, for example, the second column C2 and the fourth column C4, to increase as the distance from the boundary between the first area A1 and the second area A2 increases.

[0352] More specifically, as shown in FIG. 17, the second lens area LSA2 of the first pixel PX1 arranged in an odd-numbered row, for example, the first row R1, among the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 can emit light at a first brightness L1 lower than the reference brightness L0.

[0353] On the other hand, the second lens area LSA2 of the first pixel PX1 arranged in an even-numbered row among the plurality of first pixels PX1 arranged on the first column C1, for example, arranged in the second row R2, can emit light at the reference luminance L0.

[0354] In addition, the second lens region LSA2 of the first pixel PX1 arranged in an even-numbered row, for example, the second row R2, among the plurality of first pixels PX1 arranged in the second column C2 adjacent to the first column C1 in the first direction DR1 in the first region A1 may emit light at a second luminance L2 higher than the first luminance L1, where the second luminance L2 may be lower than the reference luminance L0.

[0355] On the other hand, the second lens area LSA2 of the first pixel PX1 arranged in an odd-numbered row among the plurality of first pixels PX1 arranged on the second column C2, for example, arranged in the first row R1, can emit light at the reference luminance L0.

[0356] Similarly, the second lens region LSA2 of the first pixel PX1 arranged in an odd-numbered row, for example, the first row R1, among the plurality of first pixels PX1 arranged in the third column C3 adjacent to the second column C2 in the first direction DR1 in the first region A1 may emit light at a third luminance L3 higher than the second luminance L2, where the third luminance L3 may be lower than the reference luminance L0.

[0357] On the other hand, the second lens area LSA2 of the first pixel PX1 arranged in an even-numbered row among the plurality of first pixels PX1 arranged on the third column C3, for example, the second row R2, can emit light at the reference luminance L0.

[0358] Similarly, among the plurality of first pixels PX1 arranged on the fourth column C4 adjacent to the third column C3 in the first direction DR1 in the first region A1, the second lens region LSA2 of the first pixel PX1 arranged on an even-numbered row, for example, the second row R2, may emit light at a fourth luminance L4 higher than the third luminance L3, where the fourth luminance L4 may be lower than the reference luminance L0.

[0359] On the other hand, the second lens area LSA2 of the first pixel PX1 arranged in an odd-numbered row among the plurality of first pixels PX1 arranged on the fourth column C4, for example, arranged in the first row R1, can emit light at the reference luminance L0.

[0360] Similarly, the second lens region LSA2 of the first pixel PX1 arranged in an even-numbered row, for example, the second row R2, among the plurality of first pixels PX1 arranged in the m-1-th column Cm-1 adjacent to the m-th column Cm farthest from the boundary between the first region A1 and the second region A2 in the opposite direction to the first direction DR1 may emit light at a fifth luminance L5 higher than the fourth luminance L4, where the fifth luminance L5 may be lower than the reference luminance L0.

[0361] On the other hand, the second lens area LSA2 of the first pixel PX1 arranged in an odd-numbered row among the multiple first pixels PX1 arranged on the m-1th column Cm-1, for example, the first pixel PX1 arranged in the first row R1, can emit light at the reference luminance L0.

[0362] Furthermore, the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the m-th column Cm on the first region A1, which is the farthest from the boundary between the first region A1 and the second region A2, can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the pixel column (m-th column Cm) farthest from the boundary between the first region A1 and the second region A2, among the plurality of first pixels PX1 arranged on the first region A1, to correspond to the input image data IDATA.

[0363] In this way, in the first mode, the display device 100 can control the luminance of the second lens regions LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 in pixel row units so that the luminance increases with increasing distance from the boundary between the first region A1 and the second region A2, for example, in the first direction DR1. For example, the display device 100 can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in odd-numbered rows, for example, the first row R1, of the plurality of first pixels PX1 arranged in odd-numbered columns, for example, the first column C1 and the third column C3, increasing from the first column C1 to the m-th column Cm, and the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in even-numbered rows, for example, the second row R2, of the plurality of first pixels PX1 arranged in even-numbered columns, for example, the second column C2 and the fourth column C4, increasing. As an example, in the first mode, the display device 100 can be controlled so that the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in a zigzag pattern on the first area A1 increases as it moves from the boundary between the first area A1 and the second area A2 in the first direction DR1.

[0364] This can minimize the problem of the boundary between the first area A1 and the second area A2 being visible when an image is displayed in the first mode.

[0365] 12, the first luminance L1 of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the odd-numbered row of the first column C1 closest to the boundary between the first region A1 and the second region A2 in the first region A1 may have a luminance corresponding to a substantially black image, for example, a value of 0. This may more effectively alleviate the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode. However, the embodiments of the present specification are not limited thereto, and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the odd-numbered row of the first column C1 closest to the boundary between the first region A1 and the second region A2 in the first region A1 may be non-emitting.

[0366] 12, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 to linearly increase as the luminance increases from the boundary between the first region A1 and the second region A2, for example, in the first direction DR1, in the first mode, thereby minimizing the problem of a luminance change in the first region A1, for example, a luminance change in the first direction DR1, being visible to the user.

[0367] 17 has been described based on the example where the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in odd-numbered rows among the plurality of first pixels PX1 arranged in odd-numbered columns increases as the display device 100 moves away from the boundary between the first region A1 and the second region A2 in the first mode, and the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in even-numbered rows among the plurality of first pixels PX1 arranged in even-numbered columns increases as the display device 100 moves away from the boundary between the first region A1 and the second region A2 in the first mode, but this is not limiting. For example, the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in even-numbered rows among the plurality of first pixels PX1 arranged in odd-numbered columns can be controlled to increase as the display device 100 moves away from the boundary between the first region A1 and the second region A2 in the first mode, and the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in odd-numbered rows among the plurality of first pixels PX1 arranged in even-numbered columns can be controlled to increase.

[0368] FIG. 18 is a diagram illustrating another example in which the display device according to an embodiment of the present specification is driven in the first mode.

[0369] Figure 18 shows an example in which the display device 100 in the first mode alternately controls the brightness of a portion of the first region A1, for example, the second lens region LSA2 of the first pixel PX1 arranged on the third region A3, on a pixel row basis.

[0370] On the other hand, FIG. 18 shows an example of the display panel PN when the display device 100 according to an embodiment of the present specification is driven in the first mode.

[0371] Referring to FIG. 18, in the first mode, the display device 100 can control the brightness of the first region A1 of the display panel PN so that the brightness of a portion of the first region A1, for example, the third region A3, increases as the distance from the boundary between the first region A1 and the second region A2 increases.

[0372] The display device 100, for example, the brightness controller LD, can control the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the third area A3 in pixel row units to increase as the distance from the boundary between the first area A1 and the second area A2 increases in the first mode.

[0373] For example, in the first mode, the display device 100, e.g., the brightness controller LD, can control the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in odd-numbered columns, e.g., the first column C1 and the third column C3, on the third area A3 so that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in odd-numbered rows, e.g., the first row R1, increases as the distance from the boundary between the first area A1 and the second area A2 increases.

[0374] In addition, in the first mode, the display device 100 can control the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in an even-numbered column on the third area A3, for example, the second column C2, to increase as the distance from the boundary between the first area A1 and the second area A2 increases.

[0375] More specifically, as shown in FIG. 18, the second lens area LSA2 of the first pixel PX1 arranged in an odd-numbered row, for example, the first row R1, among the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 can emit light at a sixth brightness L6 lower than the reference brightness L0.

[0376] On the other hand, the second lens area LSA2 of the first pixel PX1 arranged in an even-numbered row among the plurality of first pixels PX1 arranged on the first column C1, for example, arranged in the second row R2, can emit light at the reference luminance L0.

[0377] In addition, the second lens region LSA2 of the first pixel PX1 arranged in an even-numbered row, for example, the second row R2, among the plurality of first pixels PX1 arranged in the second column C2 adjacent to the first column C1 in the first direction DR1 in the first region A1 may emit light at a seventh luminance L7 higher than the sixth luminance L6, where the seventh luminance L7 may be lower than the reference luminance L0.

[0378] On the other hand, the second lens area LSA2 of the first pixel PX1 arranged in an odd-numbered row among the plurality of first pixels PX1 arranged on the second column C2, for example, arranged in the first row R1, can emit light at the reference luminance L0.

[0379] Similarly, the second lens region LSA2 of the first pixel PX1 arranged in an odd-numbered row, for example, the first row R1, among the plurality of first pixels PX1 arranged in the third column C3 adjacent to the second column C2 in the first direction DR1 in the first region A1 may emit light at an eighth luminance L8 higher than the seventh luminance L7, where the eighth luminance L8 may be lower than the reference luminance L0.

[0380] In addition, the second lens areas LSA2 of the first pixels PX1 arranged in the remaining area of ​​the first region A1 excluding the third region A3 can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of the second lens areas LSA2 of the first pixels PX1 arranged in the remaining area of ​​the first region A1 excluding the third region A3, for example, the fourth region A4, so that the luminance corresponds to the input image data IDATA.

[0381] In this way, in the first mode, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the third region A3 in pixel row units to increase as the luminance increases from the boundary between the first region A1 and the second region A2, for example, in the first direction DR1, thereby minimizing the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode.

[0382] 12, the sixth luminance L6 of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in an odd-numbered row (e.g., the first row R1) of the first column C1 closest to the boundary between the first region A1 and the second region A2 in the first region A1 may have a luminance corresponding to a substantially black image, e.g., a value of 0. This may more effectively alleviate the problem of the boundary between the first region A1 and the second region A2 being visible when an image is displayed in the first mode. However, the embodiments of the present specification are not limited thereto, and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in an odd-numbered row (e.g., the first row R1) of the first column C1 closest to the boundary between the first region A1 and the second region A2 in the first region A1 may be non-emitting.

[0383] 12, the display device 100 may control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 to linearly increase as the luminance increases from the boundary between the first region A1 and the second region A2, for example, in the first direction DR1, in the first mode, thereby minimizing the problem of a luminance change in the first region A1, for example, a luminance change in the first direction DR1, being visible to the user.

[0384] 18 has been described based on the example in which the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in odd-numbered rows among the plurality of first pixels PX1 arranged in odd-numbered columns in the third region A3 increases as the display device 100 moves away from the boundary between the first region A1 and the second region A2 in the first mode, and the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in even-numbered rows among the plurality of first pixels PX1 arranged in even-numbered columns in the third region A3 increases, but this is not limiting. For example, the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in even-numbered rows among the plurality of first pixels PX1 arranged in odd-numbered columns in the third region A3 increases as the display device 100 moves away from the boundary between the first region A1 and the second region A2 in the first mode, and the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in odd-numbered rows among the plurality of first pixels PX1 arranged in even-numbered columns in the third region A3 increase.

[0385] 18, the third region A3 of the first region A1 adjacent to the second region A2 includes three pixel columns, i.e., first to third columns C1, C2, and C3. However, this is merely an example for the convenience of explanation, and the embodiments of the present specification are not limited thereto. For example, the third region A3 may be designed to include two or fewer pixel columns, or four or more pixel columns.
