[0002] The present description relates to a display device, in particular, for example, without limitation, to a display device that can control a viewing angle. Description of the state of the art

[0003] With the advancement of technology in modern society, display devices are used in various ways to provide information to users. Display devices can be incorporated into electronic display panels that simply transmit visual information in one direction, and can also be incorporated into various high-technology electronic devices that identify user inputs and provide information in response to the identified inputs.

[0004] For example, the display device may be included in a vehicle and provide various information to a driver and a passenger in the vehicle. However, the display device in the vehicle must display content in a manner that does not interfere with the operation of the vehicle. For example, the display device must limit the display of content that could reduce the driver's concentration on controlling the vehicle while driving.

[0005] The description contained in the description of the prior art section should not be considered prior art simply because it is mentioned in or associated with the description of the prior art section. The description of the prior art section may contain information describing one or more aspects of the technology in question. SUMMARY

[0006] An object of the present description is to provide a display device that minimizes or reduces the problem of visually detecting a boundary between a first area providing content at a wide viewing angle and a second area providing content at a wide or narrow viewing angle.

[0007] The objects of the present disclosure are not limited to the above-mentioned objects, and other objects not mentioned above can be clearly understood by those skilled in the art from the following descriptions.

[0008] A display device according to an exemplary embodiment of the present disclosure includes a display panel divided into a first region having a plurality of first pixels and a second region arranged adjacent to the first region in a direction opposite to a first direction and having a plurality of second pixels, and a brightness control device configured to control the brightness of the first region, wherein the plurality of first pixels each includes a first light-emitting element arranged in a first optical region, a second light-emitting element arranged in a second optical region, a first optical component arranged in the first optical region and configured to emit light generated by the first light-emitting element at a first viewing angle, and a second optical component,which is arranged in the second optical region and configured to emit light generated by the second light-emitting element at the first viewing angle, wherein the plurality of second pixels each comprise a third light-emitting element arranged in a third optical region, a fourth light-emitting element arranged in a fourth optical region, a third optical component arranged in the third optical region and configured to emit light generated by the third light-emitting element at the first viewing angle, and a fourth optical component arranged in the fourth optical region and configured to emit light generated by the fourth light-emitting element at a second viewing angle that is smaller than the first viewing angle,and wherein the brightness control means controls the brightness of the second optical region included in each of the plurality of first pixels arranged in the first region.,

[0009] Further details of the embodiments are contained in the detailed description and the drawings.

[0010] According to the present description, it is possible to control the brightness of the display panel based on the driving mode to increase the brightness of the first area as the distance from the boundary between the first area and the second area increases in the first mode in which the content is provided in a wide viewing angle.

[0011] According to the present description, it is possible to control the brightness of the area in the first area adjacent to the boundary between the first area and the second area so that the brightness has a value substantially equal to or similar to that of the brightness of the second area, thereby solving the problem that the boundary between the first area and the second area is visually recognized.

[0032] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. All components of each display device according to all embodiments of the present disclosure are operably coupled and configured.

[0033] Fig. 1 is an exemplary view illustrating a display device according to an embodiment of the present disclosure.

[0034] With reference to Fig. 1, a display device 100 may be disposed on at least a portion of a vehicle's dashboard. The vehicle's dashboard may include a configuration disposed at a front side of a front seat (e.g., a driver's seat or a passenger seat) of the vehicle. For example, the vehicle's dashboard may be equipped with an input configuration for manipulating various functions (e.g., an air conditioning system, an audio system, and a navigation system) in the vehicle.

[0035] The display device 100 may be arranged on the dashboard of the vehicle and serve as an input for manipulating at least some of the various functions of the vehicle. The display device 100 may provide various types of information related to the vehicle, such as vehicle driving information (e.g., the current speed of the vehicle, the remaining amount of fuel, and the distance traveled), information about vehicle components (e.g., the degree of damage to a vehicle tire), and the like.

[0036] The display device 100 may be arranged to extend beyond the driver's seat and the passenger seat, which is arranged as the front seat of the vehicle. Users of the display device 100 may include a driver of the vehicle and a passenger sitting in the passenger seat. Both the driver and the passenger in the vehicle may use the display device 100.

[0037] In Fig. 1 may only illustrate a portion of the display device 100. The Fig. 1 can be illustrated as a display panel among various components included in the display device 100. In particular, for example, the display panel shown in Fig. 1 can be illustrated as at least a portion of a display area and at least a portion of a non-display area of the display panel. The components that form the Fig. 1 among the components of the display device 100 can be mounted in the vehicle (or at least a portion of the vehicle).

[0038] Fig. 2 is a functional block diagram of the display device according to the embodiment of the present specification.

[0039] As the display device according to the embodiment of the present specification, an electroluminescent display device can be used. An organic light-emitting diode display device, a quantum dot light-emitting diode display device, or an inorganic light-emitting diode display device can be used as the electroluminescent display device. However, the present disclosure is not limited thereto, and various other types of display devices can also be used as the display device according to the embodiment of the present specification.

[0040] With reference to Fig. 2, the display device 100 may include a display panel PN, a data drive circuit DD, a gate drive 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 part MD.

[0041] The display panel PN can generate an image that is provided to the user. For example, the display panel PN can generate and display images that are provided to the user via a plurality of pixels PX in which pixel circuits are arranged.

[0042] The plurality of pixels PX may include first and second pixels arranged for each area of the display panel PN. The first and second pixels and an arrangement relationship between the first and second pixels are determined with reference to the Fig. 8A to 11 are described in detail.

[0043] The data drive circuit DD, the gate drive circuit GD, and the timing controller TD may provide signals for driving the pixels PX via signal lines. For example, the signal lines for providing the signals for driving the pixels PX may include a plurality of data lines DL and a plurality of gate lines GL.

[0044] The mode selection part MD can provide signals for controlling the driving modes of the pixels PX via the signal lines. For example, the signal lines for providing the signals for controlling the driving modes of the pixels PX can include a plurality of selection signal lines SSL.

[0045] The plurality of data lines DL may include a plurality of lines arranged in a column direction and connected to the pixels PX arranged in a column direction. The plurality of gate lines GL may include a plurality of lines arranged in a row direction and connected to the pixels PX arranged in a row direction.

[0046] In addition, the plurality of selection signal lines SSL may include a plurality of lines arranged in a row direction and connected to the pixels PX arranged in a row direction.

[0047] The plurality of selection signal lines SSL may include first to fourth selection signal lines. In this case, 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 connection relationship between the first to fourth selection signal lines will be described below with reference to FIG. Fig. 8A and Fig. 9A is described in detail.

[0048] In some cases, the display device 100 may further include a power source unit. In this case, the signal for driving the pixel PX may be provided via a power line connecting the power source unit and the display panel PN. According to the embodiment, the power source unit may supply power to the data drive circuit DD and the gate drive circuit GD. The data drive circuit DD and the gate drive circuit GD may be operated based on the power provided by the power source unit.

[0049] For example, the data drive circuit DD may apply data signals to the pixels PX via the plurality of data lines DL, the gate drive circuit GD may apply gate signals to the pixels PX via the plurality of gate lines GL, and the power source unit may supply data voltages to the pixels PX via power voltage supply lines.

[0050] The brightness control device LD can receive input image data IDATA and a mode signal MODE, which are digital types and input from the outside. In this case, the mode signal MODE can be a signal input in response to the driving mode of the display device 100.

[0051] The brightness control means LD may generate 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.

[0052] For example, in a first mode in which an entire area of the display panel PN of the display device 100 is controlled in a wide field of view mode (e.g., partial mode), the brightness control means LD may generate the corrected image data CDATA for controlling the brightness of the first area.

[0053] The brightness control device LD can generate the corrected image data CDATA by scaling gradation values included in the input image data IDATA using a scaling factor. For example, the brightness control device LD can generate the corrected image data CDATA by scaling gradation values corresponding to at least a partial area, e.g., the first area of the display panel PN. However, this configuration is for illustrative purposes only. The method for generating the corrected image data CDATA by the brightness control device LD is not limited thereto.

[0054] As another example, in a second mode of the display device 100 in which at least a partial area, e.g., the first area of the display panel PN, is controlled in a wide field of view mode (e.g., partial mode) and another partial area, e.g., a second area of the display panel PN, is controlled in a narrow field of view mode (e.g., private mode), the brightness control device LD may generate the corrected image data CDATA for controlling the brightness of the entire area of the display panel PN so that the brightness corresponds to the input image data IDATA.

[0055] In the second mode, the brightness of the entire area of the display panel PN must correspond to the input image data IDATA. Therefore, the corrected image data CDATA may be substantially identical to the input image data IDATA. For example, in the second mode, the brightness control device LD may output the input image data IDATA as the corrected image data CDATA intact without correcting the input image data IDATA.

[0056] The timing controller TD can control the data drive circuit DD and the gate drive circuit GD. For example, the timing controller TD can generate image data RGB by realigning the corrected image data CDATA provided by the brightness control device LD according to the resolution of the display panel PN and supplying the image data RGB to the data drive circuit DD.

[0057] In this case, as described above, the brightness of the image displayed on at least a partial area, e.g., the first area of the display panel PN, can be controlled based on the corrected image data CDATA generated by scaling the gradation values of the input image data IDATA by the brightness control means LD when the display device 100 operates in the first mode. The configuration in which the brightness of the display panel PN is controlled based on the corrected image data CDATA will be described with reference to Fig. 12 to 18 are described in detail.

[0058] However, to simplify the description in Fig. 2 describes the configuration in which the brightness control device LD and the timing control device TD are separate components. However, the present disclosure is not limited thereto. For example, part or all of the brightness control device LD may be integrated with the timing control device TD.

[0059] The data drive circuit DD can convert the image data RGB input from the timing controller TD into an analog data signal (data voltage) based on a data drive signal and supply the data signal to the plurality of data lines DL.

[0060] The gate drive circuit GD may generate a scan signal and a light-emitting signal (or a light-emitting control signal) based on the gate control signal. For example, the gate drive circuit GD may include a scan drive part and a light-emitting signal drive part. The scan drive part may generate scan signals in a row-sequential manner to drive at least one scan line connected to each pixel row and supply the scan signals to scan lines. The light-emitting signal drive part may generate light-emitting signals in a row-sequential manner to drive at least one light-emitting signal line connected to each pixel row and supply the light-emitting signals to light-emitting signal lines.

[0061] According to the embodiment, the gate drive circuit GD may be arranged on the display panel PN in a gate driver-in-panel (GIP) manner. For example, the gate drive circuit GD may be divided into a plurality of gate drive circuits, each arranged on at least two sides of the display panel PN.

[0062] The mode controller MS can control the mode selection part MD. For example, the mode controller MS can generate a mode selection signal MSS for controlling the mode selection part MD based on the mode signal MODE input in response to the drive mode of the display device 100, and supply the mode selection signal MSS to the mode selection part MD. The mode selection part MD can supply a selection signal to the plurality of selection signal lines SSL in response to the mode selection signal MSS.

[0063] The display panel PN may include a display area and a non-display area adjacent to (e.g., surrounding) the display area.

[0064] The display area of the display panel PN may include a plurality of pixels PX arranged in the row direction and the column direction. For example, the plurality of pixels PX may be arranged in an area where the plurality of data lines DL and the plurality of gate lines GL intersect.

[0065] A pixel PX may include a plurality of subpixels that emit light rays of different colors. For example, a pixel PX may implement blue, red, and green using three subpixels. However, the present description is not limited to this. In some cases, the pixel PX may further include a subpixel for further implementing a specific color, e.g., white.

[0066] In the pixel PX, the area for implementing blue may be referred to as a blue subpixel, an area for implementing red as a red subpixel, and an area for implementing green as a green subpixel.

[0067] The plurality of pixels PX may each include light-emitting elements of a first and a second type that emit light of the same color.

[0068] The plurality of pixels PX may include at least one lens of a first or second type that refracts light rays emitted by the first and second type light-emitting elements in a specific direction. However, the term "lens" used in this description is used for convenience. Instead of the lens, the term "optical component" or "optical element" may be used.

[0069] For example, the first-type lens may be arranged in a lens region configured to define a first viewing angle by providing light within a first region, and the second-type lens may be arranged in a lens region configured to define a second viewing angle by providing light within a second region. The first region may correspond to an area larger than the second region. Therefore, the first- and second-type lenses may restrict the viewing angle of each of the plurality of pixels PX.

[0070] The lenses of the first and second types are described in detail below with reference to the Fig. 6 and Fig. 7 described.

[0071] The non-display region may be arranged along a perimeter of the display region. Various elements arranged in the pixel PX that form the pixel circuit may be arranged in the non-display region. For example, at least a portion of the gate drive circuit GD may be arranged in the non-display region. The non-display region may be referred to as a bezel region.

[0072] 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 the first region in which a plurality of first pixels among the plurality of pixels PX are arranged, and the second region in which a plurality of second pixels among the plurality of pixels PX are arranged. The plurality of first pixels arranged in a first region and the plurality of second pixels arranged in a second region may include the same pixel circuit.

[0073] For example, the plurality of first pixels arranged in the first region of the display panel PN and the plurality of second pixels arranged in the second region may each include a driving circuit, a selection circuit, and light-emitting elements of a first and a second type configured to emit light beams of the same color.

[0074] In this case, the drive circuit may be a circuit configured to provide drive currents to the light-emitting elements of the first and second types based on the signals provided by the data drive circuit DD and the gate drive circuit GD.

[0075] Additionally, the selection circuit may be a circuit configured to perform control for generating at least one of a first drive current flowing through the first-type light-emitting element and a second drive current flowing through the second-type light-emitting element based on the selection signal provided from the mode selection part MD. In other words, under the control of the selection circuit, a current path for the first drive current may be formed to allow the first-type light-emitting element to emit light, or a current path for the second drive current may be formed to allow the second-type light-emitting element to emit light. However, the present disclosure is not limited thereto. The selection circuit may be defined as being included in the drive circuit.

[0076] Meanwhile, for the convenience of description, the case where the current path for the first drive current is formed and the first-type light-emitting element emits light is defined below as a case where the pixel PX operates in a first state. The case where the current path for the second drive current is formed and the second-type light-emitting element emits light is defined as a case where the pixel PX operates in a second state.

[0077] The selection circuit can perform control to form both the first drive current flowing through the first type light-emitting element and the second drive current flowing through the second type light-emitting element based on the selection signal provided by the mode selection part MD. In other words, under the control of the selection circuit, the current path for the first drive current and the current path for the second drive current can be formed so that both the first and second type light-emitting elements can emit light.

[0078] Meanwhile, for the convenience of description, the case where the current path for the first driving current and the current path for the second driving current are formed and both the first and second type light-emitting elements emit light is defined below as a case where the pixel PX operates in a third state.

[0079] The plurality of first pixels arranged in the first region of the display panel PN may each include two lenses of a first type, e.g., a first and a second lens configured to refract light rays emitted by the first and second type light-emitting elements in a specific direction. For example, the light generated by 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 by the first lens implemented as a first type lens. The light generated by the second type light-emitting element may be refracted in a specific direction by the second lens implemented as a first type lens.

[0080] The plurality of second pixels arranged in the second region of the display panel PN may each include the first-type lens, e.g., a third lens configured to refract the light emitted by the first-type light-emitting element in a specific direction, and the second-type lens, e.g., a fourth lens configured to refract the light emitted by the second-type light-emitting element in a specific direction. For example, the light generated by 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 by the third lens implemented as a first-type lens.The light generated by 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 can be refracted in a specific direction by the fourth lens configured as a second type lens.

[0081] The plurality of regions, e.g., the first and second regions included in the display panel PN, and the first and second pixels arranged in the first and second regions will be described in detail below with reference to the Fig. 8A to 11.

[0082] According to the embodiment, the respective portions of the display panel PN may be arranged to cover the driver's seat and the passenger's seat, which are designated as front seats in the embodiment shown in FIG. Fig. 1 and provide various information to the driver and the passenger in the vehicle. For example, the first area of the display panel PN may be an area provided on one side of the driver's seat arranged on the front seat of the vehicle and providing information such as vehicle speed, engine speed, engine temperature, fuel quantity, and the like. The second area of the display panel PN may be an area provided on one side of the passenger seat arranged on the front seat of the vehicle and providing an entertainment function, seat information, and the like for the passenger sitting on the passenger seat. Meanwhile, the first area of the display panel PN may further include a central dash area arranged between the driver's seat and the passenger seat.However, the division of the regions is for convenience of description only; the present disclosure is not limited thereto. The first and second regions of the display panel PN may be defined differently according to the design.

[0083] However, when using the display panel PN for the related to Fig. 1, a field of view of at least some of the plurality of areas included in the display panel PN may be required to be restricted in response to the user's needs. For example, the image displayed in the second area, which provides the entertainment function, seat information, and the like for the passenger sitting in the front passenger seat, may obstruct the driver controlling the vehicle. Therefore, it may sometimes be necessary to restrict the field of view of the image displayed in the second area according to the user's needs.

[0084] More specifically, the display device 100 may be described with reference to Fig. 2 control the field of view of at least some of the plurality of areas included in the display panel PN using the mode control means MS and the mode selection part MD.

[0085] The mode control part MS may generate the mode selection signal MSS for controlling the display panel PN in the first or second mode according to the driving mode of the display device 100 based on the mode signal MODE, and supply the mode selection signal MSS to the mode selection part MD. In this case, the first mode may correspond to a mode in which all areas of the plurality of areas, e.g., both the first and second areas of the display panel PN, are controlled in the wide field of view mode (partial mode). The second mode may correspond to a mode in which at least some of the plurality of areas, e.g., at least one of the first and second areas of the display panel PN, e.g., the second area, are operated in the narrow field of view mode (privacy mode).

[0086] For example, when the display device 100 operates in the first and second modes, the first region of the display panel PN may operate in the third state under the control of the mode controller MS. In this case, both the first-type and second-type light-emitting elements included in each of the plurality of first pixels arranged in the first region of the display panel PN may emit light. Therefore, the light emitted from the first-type light-emitting element included in each of the plurality of first pixels may be emitted at the first viewing angle through the first lens, and the light emitted from the second-type light-emitting element included in each of the plurality of first pixels may be emitted at the first viewing angle through the second lens.Therefore, when the display device 100 operates in the first and second modes, in the wide field of view mode, the content can be provided by the plurality of first pixels arranged in the first area of the display panel PN.

[0087] Additionally, when the display device 100 operates in the first mode, the second region of the display panel PN can operate in the first state under the control of the mode control device MS. In this case, 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 can emit light, and the second-type light-emitting element cannot emit light. Therefore, the light generated by the first-type light-emitting element included in each of the plurality of second pixels can be emitted through the third lens at the first viewing angle. Therefore, when the display device 100 operates in the first mode, the content can be provided in the wide-field-of-view mode from the plurality of second pixels arranged in the second region of the display panel PN.

[0088] Furthermore, when the display device 100 operates in the second mode, the second region of the display panel PN can operate in the second state under the control of the mode control device MS. In this case, 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 can emit light, and the first-type light-emitting element cannot emit light. Therefore, the light emitted from the second-type light-emitting element included in each of the plurality of second pixels can be emitted at the second viewing angle through the fourth lens. Therefore, when the display device 100 operates in the second mode, the content can be provided in the narrow field of view mode from the plurality of second pixels arranged in the second region of the display panel PN.

[0089] The configuration in which the mode control means MS controls the display panel PN in the first or second mode according to the driving mode of the display device 100 will be described below with reference to FIG. Fig. 12 and Fig. 13 described in detail.

[0090] Fig. 3 is a circuit diagram illustrating an example of the pixel circuit of the display device according to the embodiment of the present specification.

[0091] Meanwhile, Fig. 3 shows an example of a pixel circuit SPC corresponding to each of the plurality of pixels PX of the display device 100.

[0092] With reference to Fig. 3, the pixel circuit SPC may include a drive circuit DC, a selection circuit SC, and a plurality of light-emitting elements EDa and EDb.

[0093] The drive circuit DC may include a drive transistor DT, a switching transistor ST and a first capacitor C1.

[0094] The drive transistor DT and the first capacitor C1 may be connected to the switching transistor ST. A first electrode of the drive transistor DT may be connected to a first power line configured to provide a first supply voltage VDD, e.g., a high-potential supply voltage.

[0095] The switching transistor ST can be connected to the gate line GL and supplied with the gate signal. The switching transistor ST can be turned on or off by the gate signal. The first electrode of the switching transistor ST can be connected to the data line DL. In this case, the data signal can be supplied to a gate electrode of the drive transistor DT through the switching transistor ST based on the switching transistor ST being turned on.

[0096] The first capacitor C1 may be arranged between the gate electrode and a second electrode of the drive transistor DT. The first capacitor C1 may maintain a signal applied to the gate electrode of the drive transistor DT, for example, maintain the data signal for one frame.

[0097] The selection circuit SC may include a first selection transistor TP1 configured to generate a current path for the first drive current flowing through a light-emitting element EDa of a first type, and a second selection transistor TP2 configured to generate a current path for the second drive current flowing through a light-emitting element EDb of a second type.

[0098] The first selection transistor TP1 may be arranged between the drive circuit DC and the first-type light-emitting element EDa, and a gate electrode of the first selection transistor TP1 may be connected to a first-type selection signal line configured to provide a first selection signal Ss. If the first selection signal Ss is applied to the gate electrode of the first selection transistor TP1 when the pixel circuit SPC operates in the first or third state, the first selection transistor TP1 may be turned on, so that the current path for the first drive current flowing through the first-type light-emitting element EDa may be formed. In this case, the first-type light-emitting element EDa may emit light.

[0099] The second selection transistor TP2 may be arranged between the drive circuit DC and the second-type light-emitting element EDb, and a gate electrode of the second selection transistor TP2 may be connected to a second-type selection signal line configured to provide a second selection signal Ps. If the second selection signal Ps is applied to the gate electrode of the second selection transistor TP2 when the pixel circuit SPC operates in the second or third state, the second selection transistor TP2 may be turned on, so that the current path for the second drive current flowing through the second-type light-emitting element EDb may be formed. In this case, the second-type light-emitting element EDb may emit light.

[0100] The first-type light-emitting element EDa can be connected between the first selection transistor TP1, which is switched on or off by the first selection signal Ss, and a second power line configured to provide a second supply voltage VSS, e.g., a low-potential supply voltage. The second-type light-emitting element EDb can be connected between the second selection transistor TP2, which is switched on or off by the second selection signal Ps, and the second power line configured to provide the second supply voltage VSS, e.g., the low-potential supply voltage.

[0101] In this case, the first-type light-emitting element EDa or the second-type light-emitting element EDb can be connected to other components of the pixel circuit SPC, e.g., to the drive transistor DT of the drive circuit DC, according to the drive mode MODE. In this case, the drive mode can be determined when a condition specified by user input or in advance is met.

[0102] For example, the driving mode may include the first mode in which all of the plurality of areas of the display panel PN that are connected with respect to Fig. 2 are controlled in the wide field of view mode (partial mode), and the second mode in which at least some of the plurality of areas, e.g. the second area of the display panel PN, are operated in the narrow field of view mode (private mode).

[0103] The first type light-emitting element EDa and the second type light-emitting element EDb included in a pixel circuit SPC can emit light of the same color.

[0104] The majority of transistors DT, ST, TP1 and TP2 in Fig. 3 may include at least one of oxide semiconductors such as IGZO, amorphous silicon, and polycrystalline silicon. The first or 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 a drain electrode. As another example, the first electrode may be a drain electrode and the second electrode a source electrode.

[0105] Fig. 4 is a circuit diagram illustrating an example of the pixel circuit of the display device according to the embodiment of the present specification.

[0106] However, Fig. 4 illustrate an exemplary pixel circuit SPC_1, which is used as the one in Fig. 3 illustrated pixel circuit SPC is applicable.

[0107] With reference to Fig. 4, at least one of the plurality of transistors included in the pixel circuit SPC_1 may be an n-type transistor or a p-type transistor. In the case of the p-type transistor, a low-level voltage of each of the drive signals may indicate a voltage that turns on the TFT, and a high-level voltage of each of the drive signals may indicate a voltage that turns off the TFTs.

[0108] In this case, the low-level voltage may correspond to a predetermined voltage that is lower than the high-level voltage. For example, the low-level voltage may include a voltage corresponding to a range of -8 V to -12 V. The high-level voltage may correspond to a predetermined voltage that is higher than the low-level voltage. For example, the high-level voltage may include a voltage corresponding to a range of 12 V to 16 V. According to 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 have a lower value than the second voltage.

[0109] The first or second electrode of the transistor described below may be the source or drain electrode. However, the terms "first electrode" and "second electrode" are merely used to distinguish the electrodes. There is no limitation on what corresponds to the electrode. Furthermore, the first electrode may not refer to the same electrode in each transistor.

[0110] The pixel circuit SPC_1 may include a drive circuit DC_1, a selection circuit SC_1 and the plurality of light-emitting elements EDa and EDb.

[0111] The drive circuit DC_1 may include the drive transistor DT, a plurality of switching transistors ST1 to ST5 and a second capacitor C2.

[0112] The drive transistor DT can control a drive current applied to the plurality of light-emitting elements EDa and EDb according to a source-gate voltage. The drive transistor DT can have the source electrode connected to the first power line configured to provide the first supply voltage VDD, e.g., the high-potential supply voltage, the gate electrode connected to a second node N2, and the drain electrode connected to a third node N3.

[0113] A first switching transistor ST1 may apply the data signal from the data line DL to a first node N1. The first switching transistor ST1 may include 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 configured to apply a first scan signal SCAN1. The first switching transistor ST1 may be turned on or off by the first scan signal SCAN1. Therefore, the first switching transistor ST1 may apply the data signal from the data line DL to the first node N1 in response to the first scan signal SCAN1 having a low level, for example, a turn-on level.

[0114] The second switching transistor ST2 may diode-connect the gate and drain of the driving transistor DT. The second switching transistor ST2 may include a drain connected to the second node N2, a source connected to the third node N3, and a gate connected to a second scan signal line SL2 configured to apply a second scan signal SCAN2. The second switching transistor ST2 may be turned on or off by the second scan signal SCAN2. Therefore, the second switching transistor ST2 may diode-connect the gate and drain of the driving transistor DT in response to the second scan signal SCAN2 at a low level, for example, a turn-on level.

[0115] A third switching transistor ST3 may apply a reference voltage Vref to the first node N1. The third switching transistor ST3 may include a source electrode connected to a reference voltage line configured to provide the reference voltage Vref, a drain electrode connected to the first node N1, and a gate electrode connected to a light-emitting signal line EL configured to apply a light-emitting signal EM. The third switching transistor ST3 may be turned on or off by the light-emitting signal EM. Therefore, the third switching transistor ST3 may transmit the reference voltage Vref to the first node N1 in response to the light-emitting signal EM having a low level, for example, a turn-on level.

[0116] A fourth switching transistor ST4 can apply the reference voltage Vref to an anode electrode of the first type light-emitting element EDa. The fourth switching transistor ST4 can include a source electrode connected to the reference voltage line configured to provide 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 the second scan signal line SL2 configured to apply the second scan signal SCAN2. 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 having a low level, for example, a turn-on level.

[0117] A fifth switching transistor ST5 can apply the reference voltage Vref to an anode electrode of the second type light-emitting element EDb. The fifth switching transistor ST5 can include a source electrode connected to the reference voltage line configured to provide 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 the second scan signal line SL2 configured to apply the second scan signal SCAN2. 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 having a low level, for example, a turn-on level.

[0118] 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. For example, one electrode of the second capacitor C2 may be connected to the gate electrode of the driving transistor DT, and another electrode of the second capacitor C2 may be connected to the first switching transistor ST1. The second capacitor C2 may store a predetermined voltage and maintain a predetermined voltage of the gate electrode of the driving transistor DT while at least one of the plurality of light-emitting elements EDa and EDb emits light.

[0119] The selection circuit SC_1 may include the first selection transistor TP1 configured to generate the current path for the first drive current flowing through the first type light-emitting element EDa, and the second selection transistor TP2 configured to generate the current path for the second drive current flowing through the second type light-emitting element EDb.

[0120] The first selection transistor TP1 may be arranged 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 the first-type selection signal line configured to provide the first selection signal Ss. If the first selection signal Ss is applied to the gate electrode of the first selection transistor TP1 when the pixel circuit SPC_1 is operating in the first or third state, the first selection transistor TP1 may be turned on, so that the current path for the first drive current flowing through the first-type light-emitting element EDa may be formed. In this case, the first-type light-emitting element EDa may emit light.

[0121] The second selection transistor TP2 may be arranged 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 the second-type selection signal line configured to provide the second selection signal Ps. If the second selection signal Ps is applied to the gate electrode of the second selection transistor TP2 when the pixel circuit SPC_1 is operating in the second or third state, the second selection transistor TP2 may be turned on, so that the current path for the second drive current flowing through the second-type light-emitting element EDb may be formed. In this case, the second-type light-emitting element EDb may emit light.

[0122] The first-type light-emitting element EDa can be connected between the first selection transistor TP1, which is switched on or off by the first selection signal Ss, and the second power line configured to provide the second supply voltage VSS, e.g., the low-potential supply voltage. The second-type light-emitting element EDb can be connected between the second selection transistor TP2, which is switched on or off by the second selection signal Ps, and the second power line configured to provide the second supply voltage VSS, e.g., the low-potential supply voltage.

[0123] In this case, the first-type light-emitting element EDa or the second-type light-emitting element EDb can be connected to other components of the pixel circuit SPC_1 of the pixel, e.g., to the drive transistor DT of the drive circuit DC_1 according to the drive mode MODE. In this case, the drive mode can be determined when a condition specified by user input or in advance is met.

[0124] The first type light-emitting element EDa and the second type light-emitting element EDb included in a pixel circuit SPC_1 can emit light of the same color.

[0125] The Fig. 5A and Fig. 5B are waveform diagrams for explaining the pixel circuit in Fig. 4.

[0126] Meanwhile, Fig. 5A is a waveform diagram for explaining an example in which the pixel circuit SPC_1 operates in the first state, and Fig. 5B is a waveform diagram for explaining an example in which the pixel circuit SPC_1 operates in the second state.

[0127] With reference to the Fig. 4 to 5B, only the first-type light-emitting element EDa emits light if the pixel circuit SPC_1 operates in the first state, and only the second-type light-emitting element EDb can emit light if the pixel circuit SPC_1 operates in the second state. In this case, as shown in Fig. 5A, in the first state, the second selection signal Ps used to control the light emission from the second type light-emitting element EDb, for example, the second selection signal Ps used to form the current path for the second drive current, may be output only at a high level, for example, a cut-off level, so that only the first type light-emitting element EDa emits light. In addition, as shown in Fig. 5B illustrates that in the second state, the first selection signal Ss used to control the light emission from the first type light-emitting element EDa, for example, the first selection signal Ss used to form the current path for the first drive current, is output only at a high level, for example, a turn-off level, so that only the second type light-emitting element EDb emits light.

[0128] In particular, the case where the pixel circuit SPC_1 operates in the first state is first discussed with reference to the Fig. 4 and Fig. 5A. During an initialization period, the second scan signal SCAN2 may be output at a low level, the first selection signal Ss at a low level, and the light-emitting signal EM at a low level. The second switching transistor ST2, the fourth switching transistor ST4, and the fifth switching transistor ST5 may be turned on by the second scan signal SCAN2 at a low level, the first selection transistor TP1 may be turned on by the first selection signal Ss at a low level, and the third switching transistor ST3 may be turned on by the light-emitting signal EM at a low level.

[0129] The first node N1 can be initialized to the reference voltage Vref by the turned-on third switching transistor ST3. The voltage of the anode electrode of the first-type light-emitting element EDa can be initialized to the reference voltage Vref by the turned-on fourth switching transistor ST4, and the voltage of the anode electrode of the second-type light-emitting element EDb can be initialized to the reference voltage Vref by the turned-on fifth switching transistor ST5. In addition, the driving transistor DT is connected as a diode via the turned-on second switching transistor ST2, and the gate and drain of the driving transistor DT are short-circuited, allowing the driving transistor DT to operate as a diode.Furthermore, the reference voltage Vref transmitted to the anode electrode of the first type light-emitting element EDa by the turned-on fourth switching transistor ST4 can be transmitted to the third node N3 and the second node N2 by the turned-on first selection transistor TP1, so that the third node N3 and the second node N2 can be initialized to the reference voltage Vref.

[0130] Next, during a sampling period, the first scan signal SCAN1 at a low level and the second scan signal SCAN2 at a low level may be output, and the first selection signal Ss may be output at a high level. When the light-emitting signal EM is output at a high level, the first switching transistor ST1 is turned on by the first scan signal SCAN1 at a low level, while simultaneously turning off the third switching transistor ST3, so that the data signal can be transmitted to the first node N1. Furthermore, the drive transistor DT is diode-connected by the turned-on second switching transistor ST2, and a difference between the first power supply voltage VDD and the threshold voltage may be sensed and supplied to the second node N2.

[0131] Furthermore, during a hold period, the first scan signal SCAN1 and the second scan signal SCAN2 may be 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 may all be turned off. However, even when the first switching transistor ST1 is turned off, the data signal (data voltage) input during the previous period (e.g., the sampling period) can be maintained by the second capacitor C2.

[0132] Finally, during a light-emitting period, the first selection signal Ss and the light-emitting signal EM may be output at a low level, and the second selection signal Ps may be output at a high level. The reference voltage Vref may be applied to the first node N1 through the third switching transistor ST3, which is turned on by the low-level light-emitting signal EM. A voltage of the first node N1 may be a voltage difference between the reference voltage Vref and the data signal (data voltage), and this voltage change may also be applied to the second node N2. A gate-source voltage of the drive transistor DT may be set to a value (Vdata-Vref+Vth) formed by subtracting the reference voltage Vref from the data signal (data voltage) and adding the threshold voltage Vth, thereby controlling the first drive current.

[0133] Furthermore, the first drive current is supplied from the drive transistor DT to the first-type light-emitting element EDa via the turned-on first selection transistor TP1, so that the first-type light-emitting element EDa can emit light. However, the second selection signal Ps is output at a high level and the second selection transistor TP2 is turned off, so the second drive current is not transmitted from the drive transistor DT to the second-type light-emitting element EDb. Therefore, when the pixel circuit SPC_1 operates in the first state, the first drive current can only be applied to the first-type light-emitting element EDa, and only the first-type light-emitting element EDa can emit light.

[0134] Next, the case where the pixel circuit SPC_1 operates in the second state will be described with reference to the Fig. 4 and Fig. 5B. The pixel circuit SPC_1 may operate in the second state in substantially the same manner as when the pixel circuit SPC_1 operates in the first state, except that the first selection signal Ss and the second selection signal Ps are output in a manner opposite to the first state. For example, the first selection signal Ss may be output only at a high level, such as a turn-off level, and the second selection signal Ps may be output at a low level, such as a turn-on level, during the light-emitting period in which the second-type light-emitting element EDb emits light.

[0135] 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. Furthermore, the first selection signal Ss may be output at a high level, and the second selection signal Ps and the light-emitting signal EM may be output at a low level. Therefore, the second switching transistor ST2, the fourth switching transistor ST4, and the fifth switching transistor ST5 may be turned on by the second scan signal SCAN2, the second selection transistor TP2 may be turned on by the second selection signal Ps, and the third switching transistor ST3 may be turned on by the light-emitting signal EM.

[0136] The first node N1 can be initialized to the reference voltage Vref by the third switching transistor ST3, which is turned on by the light-emitting signal EM, and the anode electrodes of the first- and second-type light-emitting elements EDa and EDb can be initialized to the reference voltage Vref by the fourth switching transistor ST4 and the fifth switching transistor ST5, which are turned on by the second scan signal SCAN2. Furthermore, the driving transistor DT can be connected as a diode via the turned-on second switching transistor ST2 and operate as a diode.Finally, the reference voltage Vref transmitted to the anode electrode of the second type light-emitting element EDb by the turned-on fifth switching transistor ST5 can be transmitted to the third node N3 and the second node N2 by the turned-on second selection transistor TP2, so that the third node N3 and the second node N2 can be initialized to the reference voltage Vref.

[0137] Next, during the sampling period, the first scan signal SCAN1 may be output at a low level and the second scan signal SCAN2 at a low level, and the second selection signal Ps and the light-emitting signal EM may be output from a low level to a high level. When the light-emitting signal EM is output at a high level, the third switching transistor ST3 may be turned off, and the first switching transistor ST1 may be turned on by the first scan signal SCAN1 at a low level, so that the data signal can be transmitted to the first node N1. Furthermore, the drive transistor DT is diode-connected by the turned-on second switching transistor ST2, and the voltage difference between the first power supply voltage VDD and the threshold voltage may be sampled and supplied to the second node N2.

[0138] Finally, during the light-emitting period, the second selection signal Ps and the light-emitting signal EM may be output at a low level, and the first selection signal Ss may be output at a high level. The reference voltage Vref may be 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 of the first node N1 may be a voltage difference between the reference voltage Vref and the data signal (data voltage), and this voltage change may also be applied to the second node N2. The gate-source voltage of the drive transistor DT may be set to a value (Vdata-Vref+Vth) obtained by subtracting the reference voltage Vref from the data signal (data voltage) and adding the threshold voltage Vth, thereby controlling the second drive current.

[0139] Furthermore, the second drive current is supplied from the drive transistor DT to the second-type light-emitting element EDb via the turned-on second selection transistor TP2, so that the second-type light-emitting element EDb can emit light. However, the first selection signal Ss is output at a high level and the first selection transistor TP1 is turned off, so that the first drive current is not transmitted from the drive transistor DT to the first-type light-emitting element EDa. Therefore, when the pixel drive circuit SPC_1 operates in the second state, the second drive current can only be applied to the second-type light-emitting element EDb, and only the second-type light-emitting element EDb can emit light.

[0140] However, although in the Fig. 5A and Fig. 5B, both the first-type light-emitting element EDa and the second-type light-emitting element EDb emit light if the pixel circuit SPC_1 operates in the third state. Therefore, the waveform of the first selection signal Ss and the operation of the pixel circuit SPC_1 generating the first drive current according to the waveform of the first selection signal Ss in the third state are substantially identical to or similar to the waveform of the first selection signal Ss and the operation of the pixel circuit SPC_1 generating the first drive current according to the waveform of the first selection signal Ss in the first state, as shown in Fig. 5A. Furthermore, the waveform of the second selection signal Ps and the operation of the pixel circuit SPC_1 that generates the second drive current according to the waveform of the second selection signal Ps in the third state are substantially identical to or similar to the waveform of the second selection signal Ps and the operation of the pixel circuit SPC_1 that generates the second drive current according to the waveform of the second selection signal Ps in the second state described with reference to Fig. 5B. Therefore, repeated description is omitted.

[0141] Fig. 6 and Fig. 7 are cross-sectional views of the display device according to the embodiment of the present specification.

[0142] Fig. Figure 6 illustrates a pixel in which a lens 161 of a first type is arranged, and Fig. Figure 7 illustrates a pixel in which a lens 162 of a second type is arranged.

[0143] With reference to the Fig. 6 and Fig. 7, the display device 100 according to the embodiment of the present description may include a substrate 110, a buffer film 111, a gate insulating film 112, an interlayer insulating film 113, a lower protective film 114, a cap layer 115, a bank insulating film 116, the first selection transistor TP1, the second selection transistor TP2, the first type light-emitting element EDa, the second type light-emitting element EDb, the first type lens 161, the second type lens 162, a lens protective film 170, and an encapsulating member 180.

[0144] The substrate 110 may include an insulating material. The substrate 110 may include a transparent material. For example, the substrate 110 may include glass, plastic, or a flexible polymer film. For example, the flexible polymer film may be formed from any of polyethylene terephthalate (PET), polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA), polyethylene naphthalate (PEN), polyethersulfone (PES), cyclic olefin copolymer (COC), triacetyl cellulose (TAC) film, polyvinyl alcohol (PVA) film, polyimide (PI) film, and polystyrene (PS), which is only an example and not necessarily limited thereto.

[0145] The 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 multilayer structure. For example, the buffer film 111 may have a stacked structure including a silicon nitride (SiNx) film and a silicon oxide (SiOx) film, but the present disclosure is not limited thereto.

[0146] The buffer film 111 can be positioned between the substrate 110 and a driving part, e.g., the driving circuit DC of each of the pixels PX. The buffer film 111 can suppress or reduce contamination caused by the substrate 110 during a process of forming the driving part. For example, an upper surface of the substrate 110 facing the driving part of each of the pixels PX can be covered by the buffer film 111. The driving part of each of the pixels PX can be positioned on the buffer film 111.

[0147] The gate insulating film 112 may be disposed on the buffer film 111. The gate insulating film 112 may include an insulating material. For example, the gate insulating film 112 may include an inorganic insulating material such as silicon oxide (SiOx) and silicon nitride (SiNx). The gate insulating film 112 may include a high-dielectric constant material. For example, the gate insulating film 112 may include a high-K material such as hafnium oxide (HfO). The gate insulating film 112 may have a multilayer structure.

[0148] The gate insulating film 112 may extend between the semiconductor layers 121 and 131 and the gate electrodes 122 and 132 of the selection transistors TP1 and TP2. For example, the gate electrodes of the switching transistor ST and the drive transistor DT may be insulated from the semiconductor layers of the switching transistor ST and the drive transistor DT by the gate insulating film 112. The gate insulating film 112 may cover the semiconductor layer of each of the pixels PX. The gate electrodes of the switching transistor ST and the drive transistor DT may be positioned on the gate insulating film 112.

[0149] The insulating interlayer film 113 may be disposed on the gate insulating film 112. The insulating interlayer film 113 may include an insulating material. For example, the insulating interlayer film 113 may include an inorganic insulating material such as silicon oxide (SiOx) and silicon nitride (SiNx). The insulating interlayer film 113 may extend between the gate electrodes and the source electrodes, and between the gate electrodes and the drain electrodes of the driving transistor DT and the switching transistor ST. For example, the source electrodes and the drain electrodes of the driving transistor DT and the switching transistor ST may be insulated from the gate electrodes by the insulating interlayer film 113. The insulating interlayer film 113 may cover the gate electrodes of the switching transistor ST and the driving transistor DT.The source electrode and drain electrode in each of the pixels PX may be positioned on the interlayer insulating film 113. The gate insulating film 112 and the interlayer insulating film 113 may expose the source and drain regions of each semiconductor structure positioned in each of the pixels PX.

[0150] The lower protective film 114 may be disposed on the insulating interlayer film 113. The lower protective film 114 may include an insulating material. For example, the lower protective film 114 may include an inorganic insulating material such as silicon oxide (SiOx) and silicon nitride (SiNx). The lower protective film 114 may suppress or reduce damage to the driving part caused by external moisture and shock. The lower protective film 114 may extend along a surface of the driving transistor DT and a surface of the switching transistor ST that are opposite to the substrate 110. The lower protective film 114 may be in contact with the insulating interlayer film 113 outside the driving part positioned in each of the pixels PX.

[0151] The cap layer 115 may be disposed on the lower protective film 114. The cap layer 115 may include an insulating material. The cap layer 115 may include a material different from the material of the lower protective film 114. For example, the cap layer 115 may include an organic insulating material. For example, the cap layer 115 may include one or more of acrylic resin, epoxy resin, phenolic resin, polyamide resin, unsaturated polyester resin, polyphenylene resin, polyphenylene sulfide resin, and benzocyclobutene, but the embodiments are not limited thereto. The cap layer 115 may eliminate a height difference caused by the driving part in each of the pixels PX. For example, an upper surface of the cap layer 115 facing the substrate 110 may be a flat surface.

[0152] The first selection transistor TP1 and the second selection transistor TP2 may be arranged on the substrate 110. The first selection transistor TP1 may be electrically connected between the drain electrode of the drive transistor DT and a first lower 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 drive transistor DT and a second lower electrode 151 of the second-type light-emitting element EDb.

[0153] 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 or a similar structure as the switching transistor ST and the driving transistor DT. For example, the first semiconductor layer 121 may be positioned between the buffer film 111 and the gate insulating film 112, and the first gate electrode 122 may be positioned 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 positioned between the interlayer insulating film 113 and the lower protection 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.

[0154] The second selection transistor TP2 may include a second semiconductor layer 131, a second gate electrode 132, a second source electrode 133, and a second drain electrode 134. For example, the second semiconductor layer 131 may be positioned on the same layer as the first semiconductor layer 121, the second gate electrode 132 may be positioned on the same layer as the first gate electrode 122, and the second source electrode 133 and the second drain electrode 134 may be positioned on the same layer as the first source electrode 123 and the first drain electrode 124.

[0155] The first type light-emitting element EDa and the second type light-emitting element EDb in each of the pixels PX may be arranged on the cover layer 115 in the corresponding pixel PX.

[0156] The first-type light-emitting element EDa can emit light of a specific color. For example, the first-type light-emitting element EDa can include the first lower electrode 141, a first light-emitting layer 142, and a first upper electrode 143, which are sequentially stacked on the substrate 110.

[0157] The first lower electrode 141 may include an electrically conductive material. The first lower electrode 141 may include a material with high reflectivity. For example, the first lower electrode 141 may include metal such as aluminum (Al) and silver (Ag). The first lower electrode 141 may have a multilayer structure. For example, the first lower electrode 141 may have a structure in which a reflective electrode made of metal is positioned between transparent electrodes made of a transparent conductive material such as ITO and IZO. The first lower electrode 141 may be electrically connected to the first drain electrode 124 of the first selection transistor TP1 through contact holes formed by the lower protective film 114 and the cap layer 115.

[0158] The first light-emitting layer 142 can generate light with a brightness corresponding to a 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 emissive material layer (EML) containing a light-emitting material. The light-emitting material can include an organic material, an inorganic material, or a hybrid material.

[0159] 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).

[0160] The first upper electrode 143 may include an electrically conductive material. The first upper electrode 143 may include a material different from the material of the first lower electrode 141. A transmittance of the first upper electrode 143 may be higher than a transmittance of the first lower electrode 141. For example, the first upper electrode 143 may be configured as a transparent electrode made of a transparent conductive material such as ITO and IZO. Therefore, in the display device 100 according to the embodiment of the present description, the light generated by the first light-emitting layer 142 can be emitted through the first upper electrode 143.

[0161] The second type light-emitting element EDb may have the same color as the first type light-emitting element EDa. The second type light-emitting element EDb may have the same or a similar structure to the first type light-emitting element EDa. For example, the second type light-emitting element EDb may include the second lower electrode 151, a second light-emitting layer 152, and a second upper electrode 153 stacked sequentially on the substrate 110.

[0162] 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 for the second-type light-emitting element EDb while having the same or a similar structure to the first lower electrode 141. The same may apply to 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 or a similar structure. However, the present description is not limited to this.In some cases, the first type light-emitting element EDa and the second type light-emitting element EDb may be formed to differ from each other in at least some configurations.

[0163] The second light-emitting layer 152 may be spaced apart from the first light-emitting layer 142. Therefore, in the display device according to the embodiment of the present description, it is possible to suppress or reduce the light emission caused by a leakage current.

[0164] The second lower electrode 151 in each of the pixels PX may be spaced apart from the first lower electrode 141 in the corresponding pixel PX. For example, the bank insulating film 116 may be disposed between the first lower electrode 141 and the second lower electrode 151 in each of the pixels PX. The bank insulating film 116 may include an insulating material. For example, the bank insulating film 116 may include an organic insulating material such as acrylic resin, epoxy resin, phenolic resin, polyamide resin, and / or polyimide resin, etc. Alternatively, the bank insulating film 116 may include an inorganic insulating material such as silicon nitride, aluminum nitride, zirconium nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, or titanium oxide, etc. The bank insulating film 116 may include a material different from the material of the cap layer 115. In addition, the bank insulating film 116 serves to define a pixel or sub-pixel.Thus, the bank insulating film 116 may be made of an insulating material containing a black material. For example, the bank insulating film 116 may be made of a transparent carbon-based mixture. In particular, the bank insulating film 116K may contain, but is not limited to, carbon black. The bank insulating film 116 may also be made of a transparent insulating material.

[0165] The second lower electrode 151 in each of the pixels PX may be insulated from the first lower electrode 141 in 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 positioned in each of the pixels PX. Therefore, the display device 100 can provide the user with images formed by a first-type lens region LSAa in each of the pixels PX in which the first-type light-emitting element EDa is positioned, or by a second-type lens region LSAb in each of the pixels PX in which the second-type light-emitting element EDb is positioned.

[0166] The first light-emitting layer 142 and the first upper electrode 143 of the first-type light-emitting element EDa, positioned in each of the pixels PX, may be stacked in 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, positioned in each of the pixels PX, may be stacked in a portion of the corresponding second lower electrode 151 exposed by the bank insulating film 116.For example, in each of the pixels PX, the bank insulating film 116 may be divided into a first-type light-emitting region EAa in which light is emitted by the first-type light-emitting element EDa, and a second-type light-emitting region EAb in which light is emitted by the second-type light-emitting element EDb. In each of the pixels PX, a size of the defined second-type light-emitting region EAb may be smaller than a size of the defined first-type light-emitting region EAa.

[0167] In each of the pixels PX, the second upper electrode 153 may be electrically connected to the first upper electrode 143 in the corresponding pixel PX. For example, a voltage applied to the second upper electrode 153 of the second type light-emitting element EDb positioned in each of the pixels PX may be equal to a voltage applied to the first upper electrode 143 of the first type light-emitting element EDa positioned in the corresponding pixel PX. The second upper electrode 153 in each of the pixels PX may include the same material as the first upper electrode 143 in the corresponding pixel PX. For example, the second upper electrode 153 in each of the pixels PX may be formed simultaneously with the first upper electrode 143 in the corresponding pixel PX.The second upper electrode 153 in each of the pixels PX may extend on the bank insulating film 116 and be in direct contact with the first upper electrode 143 in the corresponding pixel PX. The brightness of the first-type lens region LSAa positioned in each of the pixels PX and the brightness of the second-type lens region LSAb positioned in each of the pixels PX may be controlled by the drive current generated in the corresponding pixel PX.

[0168] The encapsulation member 180 can be positioned on the first-type light-emitting element EDa and the second-type light-emitting element EDb in each of the pixels PX. The encapsulation member 180 can suppress or reduce damage to the light-emitting elements EDa and EDb caused by moisture and external impact. The encapsulation member 180 can have a multi-layer structure. For example, the encapsulation member 180 can include a first encapsulation layer 181, a second encapsulation layer 182, and a third encapsulation layer 183 stacked sequentially. However, the present description is not limited to this. The first encapsulation layer 181, the second encapsulation layer 182, and the third encapsulation layer 183 can include an insulating material.The second encapsulation layer 182 may contain a material different from the material of the first encapsulation layer 181 and the third encapsulation layer 183. For example, the first encapsulation layer 181 and the third encapsulation layer 183 are inorganic encapsulation layers containing an inorganic insulating material, and the second encapsulation layer 182 may contain an organic encapsulation layer containing an organic insulating material. Therefore, damage to the light-emitting elements EDa and EDb of the display device 100 caused by moisture and external influences can be more effectively suppressed or reduced.

[0169] The first type lens 161 and the second type lens 162 may be arranged on the encapsulation component 180.

[0170] The first-type lens 161 may be disposed on the first-type light-emitting element EDa. The light generated by the first-type light-emitting element EDa in each of the pixels PX may be emitted through the first-type lens 161 in the corresponding pixel PX. The first-type lens 161 may have a shape in which light is not restricted at least in one direction. For example, a planar shape of the first-type lens 161 positioned in each of the pixels PX may be a bar shape extending in one direction.

[0171] In this case, a propagation direction of light emitted from the first-type lens area LSAa in each of the pixels PX may not be limited to one direction. For example, the content (or images) provided by the first-type lens area LSAa in each of the pixels PX may be shared with people adjacent to the user in one direction. Therefore, the content provided by the light emitted by the first-type lens 161 may be provided in a first viewing angle range having a wider viewing angle than the content provided by the light emitted by the second-type lens 162. For example, the content provided by the light emitted by the first-type lens 161 may be provided in a wide-field-of-view mode (shared mode).

[0172] The second-type lens 162 may be disposed on the second-type light-emitting element EDb. The light generated by the second-type light-emitting element EDb in each of the pixels PX may be emitted through the second-type lens 162 in the corresponding pixel PX. The second-type lens 162 may restrict the propagation direction in which the light passes through the second-type lens 162 to one direction and / or another direction. For example, a planar shape of the second-type lens 162 positioned in each of the pixels PX may be a circular shape.

[0173] In this case, the propagation direction of the light emitted by the second-type lens region LSAb in each of the pixels PX may be limited to one direction and / or another direction. For example, the content (or images) provided by the second-type lens region LSAb in each of the pixels PX may not be shared with people adjacent to the user in one direction. Therefore, the content provided by the light emitted by the second-type lens 162 may be provided in a second viewing angle range that has a smaller viewing angle than the content provided by the light emitted by the first-type lens 161. For example, the content provided by the light emitted by the second-type lens 162 may be provided in a narrow-field-of-view mode (private mode).

[0174] The first-type light-emitting region EAa provided in each of the pixels PX may have a shape corresponding to the first-type lens 161 in each of the pixels PX. For example, a planar shape of the first-type light-emitting region EAa in each of the pixels 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 in the corresponding pixel PX. Therefore, it is possible to improve the efficiency of the light emitted from the first-type light-emitting region EAa in the pixel PX.

[0175] The second-type light-emitting region EAb in each of the pixels PX may have a shape corresponding to the second-type lens 162 in each of the pixels PX. For example, a planar shape of the second-type light-emitting region EAb in each of the pixels PX may be a circular shape. The second-type lens 162 may have a larger size than the second-type light-emitting region EAb in the corresponding pixel PX. Therefore, it is possible to improve the efficiency of the light emitted by the second-type light-emitting region EAb in the pixel PX.

[0176] With reference to Fig. 6, if the pixel PX includes the first-type lens 161, the first-type lens region LSAa in which the first-type lens 161 is arranged may include a light-emitting region, e.g., a first-type light-emitting region EAa. In addition, with reference to Fig. 7, if the pixel PX includes the second type lens 162, the second type lens region LSAb in which the second type lens 162 is arranged may include a plurality of light-emitting regions, e.g., a plurality of second type light-emitting regions EAb.

[0177] With reference to Fig. 6, in the case where the pixel PX includes the first-type lens 161, one first-type lens 161 may be disposed in the first-type lens region LSAa. Therefore, the number of light-emitting regions EAa of the first-type light-emitting element EDa defined by the bank insulating film 116 may be one, which corresponds to one first-type lens 161.

[0178] In addition, with reference to Fig. 7, if the pixel PX includes the second-type lens 162, the two second-type lenses 162 may be arranged in the second-type lens region LSAb. Therefore, the number of the second-type light-emitting regions 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. However, the present disclosure is not limited to this; the number of the second-type light-emitting regions EAb of the second-type light-emitting element EDb defined by the bank insulating film 116 may be three or more, and the planar shape of the second-type light-emitting region EAb in each of the pixels PX may have various shapes other than the circular shape, such as an ellipse or oval shape.

[0179] The lens protection film 170 may be positioned on the first-type lens 161 and the second-type lens 162 in 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. A refractive index of the lens protection film 170 may be smaller than a refractive index of the first-type lens 161 and a refractive index of the second-type lens 162 positioned in each of the pixels PX. Therefore, in the display device 100 according to the embodiment of the present description, the light that has passed through the first-type lens 161 and the second-type lens 162 in each of the pixels PX may not be reflected to the substrate 110 due to a difference from the refractive index of the lens protection film 170.

[0180] With reference to the Fig. 6 and Fig. 7, as described above, the pixel PX may include the first-type lens 161 disposed over the first-type light-emitting element EDa and the second-type lens 162 disposed over the second-type light-emitting element EDb. However, the present disclosure is not limited thereto.

[0181] For example, the pixel PX may include the plurality of first-type lenses 161 arranged over the first-type light-emitting element EDa and the second-type light-emitting element EDb. This configuration will be described below with reference to Fig. 8A and Fig. 8B is described in detail.

[0182] Fig. 8A is a circuit diagram illustrating an example of the first pixel of the display device according to the embodiment of the present specification. Fig. 8B is a plan view schematically illustrating an example of the first pixel of the display device according to the embodiment of the present specification.

[0183] Meanwhile, the Fig. 8A and Fig. 8B shows an example of a first pixel PX1 from the plurality of pixels PX formed on the display panel PN of the display device 100 according to the embodiment described with reference to Fig. 2 described embodiment of the present description.

[0184] Meanwhile, the first pixel PX1, illustrated in Fig. 8A, containing the pixel circuit SPC, described with reference to Fig. 3, or the pixel circuit SPC_1, described with reference to Fig. 4. Therefore, a repeated description of the contents related to the Fig. 3 and Fig. 4 are identical in content, are omitted.

[0185] In addition, the Fig. 8A and Fig. 8B illustrates only the selection circuit, the plurality of light-emitting elements, and the plurality of lenses among the components included in the first pixel PX1. For simplicity of description, Fig. 8A schematically shows only a corresponding relationship between the plurality of lenses, which is indicated by the dashed line.

[0186] Firstly, the first pixel PX1 can be identified with respect to the Fig. 3, Fig. 4 and Fig. 8A includes a first selection circuit SC1 and a plurality of light-emitting elements ED1 and ED2.

[0187] The first selection circuit SC1 may include a first transistor T1 and a second transistor T2. The first transistor T1 and the second transistor T2 in Fig. 8A may be transistors corresponding respectively to the first selection transistor TP1 and the second selection transistor TP2, which are shown with reference to the Fig. 3 and Fig. 4 are described.

[0188] A gate electrode of the first transistor T1 may be turned on or off in response to a selection signal provided by a first selection signal line SSL1, and a gate electrode of the second transistor T2 may be turned on or off in response to a selection signal provided by a second selection signal line SSL2. In this case, the selection signal provided by the first selection signal line SSL1 and the selection signal provided by the second selection signal line SSL2 may be the first selection signal Ss and the second selection signal Ps, respectively, which may be Fig. 3 and Fig. 4. However, the present disclosure is not limited thereto.

[0189] 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 identical or similar to the one with respect to the Fig. 3 and Fig. 4, the first light-emitting element ED1 of the first pixel PX1 can be connected between the first transistor T1 and the second power line configured to provide the second supply voltage VSS, e.g., the low-potential supply voltage, and the second light-emitting element ED2 of the first pixel PX1 can be connected between the second transistor T2 and the second power line configured to provide the second supply voltage VSS. For example, the first light-emitting element ED1 and the second light-emitting element ED2 can be connected in Fig. 8A light-emitting elements corresponding respectively to the first type light-emitting element EDa and the second type light-emitting element EDb, which are shown with reference to the Fig. 3 and Fig. 4 are described.

[0190] Therefore, when the first transistor T1 is turned on in response to the selection signal at a turn-on level provided from the first selection signal line SSL1, the first drive current flowing through the first light-emitting element ED1 can be formed so that the first light-emitting element ED1 of the first pixel PX1 can emit light.

[0191] In addition, when the second transistor T2 is turned on in response to the selection signal at a turn-on level provided from the second selection signal line SSL2, the second drive current flowing through the second light-emitting element ED2 can be formed so that the second light-emitting element ED2 of the first pixel PX1 can emit light.

[0192] The first pixel PX1 can operate in the third state in which both the first light-emitting element ED1 and the second light-emitting element ED2 emit light.

[0193] The first pixel PX1 may include a first lens LS1 arranged above the first light-emitting element ED1 and a second lens LS2 arranged above the second light-emitting element ED2.

[0194] With reference to Fig. 8B to describe the first lens LS1 and the second lens LS2 in more detail, 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 positioned, respectively.

[0195] The first lens area LSA1 and the second lens area LSA2 can provide images at substantially the same viewing angle. The brightness of the first lens area LSA1 can be controlled by the first drive current generated by the first light-emitting element ED1, and the brightness of the second lens area LSA2 can be controlled by the second drive current generated by the second light-emitting element ED2.

[0196] The first lens LS1 can be positioned over the first light-emitting element ED1, and the second lens LS2 can be positioned over the second light-emitting element ED2.

[0197] 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 in which at least light cannot be restricted in one direction. For example, a planar shape of the first lens LS1 and the second lens LS2 positioned in the first pixel PX1 may be a bar shape extending in one direction. For example, the first lens LS1 and the second lens LS2 may each be implemented as a first type lens 161, as described with reference to Fig. 6 described.

[0198] 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 propagation direction of the corresponding light may not be limited to one direction.

[0199] A first light-emitting region 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 a second light-emitting region EA2 defined by the second light-emitting element ED2 of the first pixel PX1 may have a shape corresponding to the second lens LS2.

[0200] For example, as in Fig. 8B illustrates, a planar shape of the first light-emitting region EA1 and a planar shape of the second light-emitting region EA2 may each be a bar shape extending in a direction to correspond to the shape of the first lens LS1 and the shape of the second lens LS2. Furthermore, in this case, the first lens LS1 positioned 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 positioned in the second lens region LSA2 may be larger than the second light-emitting region EA2 included in the second lens region LSA2. Therefore, it is possible to improve the efficiency of the light emitted from the first light-emitting region EA1 and the second light-emitting region EA2 of the first pixel PX1.

[0201] Since the first lens LS1 and the second lens LS2 are implemented as a lens of the first type 161, the first lens region LSA1 and the second lens region LSA2 may each include a light-emitting region, e.g., a first light-emitting region EA1 and a second light-emitting region EA2, and a lens, e.g., a first lens LS1 and a second lens LS2, as described with reference to Fig. 6 described.

[0202] Therefore, in the case where the first drive current is generated 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 as a first-type lens 161. Therefore, the content provided by the light generated by the first light-emitting element ED1 of the first pixel PX1 can be provided at the first viewing angle. For example, the provided content (or images) can be shared with people located adjacent to the user in a direction. Therefore, the content provided by the light emitted by the first lens LS1 can be provided in the wide field of view mode (shared mode).

[0203] In addition, in the case where the second drive current is generated 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 as a first-type lens 161. Therefore, the content provided by the light generated by the second light-emitting element ED2 of the first pixel PX1 can be provided at the first viewing angle. For example, the provided content (or images) can be shared with people located adjacent to the user in a direction. Therefore, the content provided by the light emitted by the second lens LS2 can be provided in the wide field of view mode (shared mode).

[0204] For example, in the case of the first pixel PX1, both 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 be provided at the first viewing angle.

[0205] In this case, as described above, the first pixel PX1 can operate in the third state, in which both the first light-emitting element ED1 and the second light-emitting element ED2 emit light. Therefore, when the first pixel PX1 operates in the third state, the content at the first viewing angle can be provided by the light generated by the first light-emitting element ED1 and the light generated by the second light-emitting element ED2.

[0206] As described above, the first region in which the first pixel PX1 operating in the third state is arranged among the plurality of regions of the display panel PN can provide the content in the wide field of view mode regardless of the driving mode.

[0207] Fig. 9A is a circuit diagram illustrating an example of the second pixel of the display device according to the embodiment of the present specification. Fig. 9B is a plan view schematically illustrating an example of the second pixel of the display device according to the embodiment of the present specification.

[0208] Meanwhile, the Fig. 9A and Fig. 9B shows an example of a second pixel PX2 from the plurality of pixels PX formed on the display panel PN of the display device 100 according to the embodiment described with reference to Fig. 2 described embodiment of the present description.

[0209] However, this can Fig. 9A illustrated second pixel PX2 which with reference to Fig. 3 described pixel circuit SPC or the one with reference to Fig. 4. Therefore, a repeated description of the contents related to the circuits described with reference to Fig. 3 and Fig. 4 are identical in content, are omitted.

[0210] Additionally, the Fig. 9A and Fig. 9B illustrates only the selection circuit, the plurality of light-emitting elements, and the plurality of lenses among the components included in the second pixel PX2. For simplicity of description, Fig. 9A schematically shows only a corresponding relationship between the plurality of lenses, which is indicated by the dashed line.

[0211] First, the second pixel PX2 can be compared with the Fig. 3, Fig. 4 and Fig. 9A, a second selection circuit SC2 and a plurality of light-emitting elements ED3 and ED4.

[0212] The second selection circuit SC2 may include a third transistor T3 and a fourth transistor T4. The third transistor T3 and the fourth transistor T4 in Fig. 9A may be transistors corresponding respectively to the first selection transistor TP1 and the second selection transistor TP2, which are shown with reference to the Fig. 3 and Fig. 4 are described.

[0213] A gate electrode of the third transistor T3 may be turned on or off in response to a selection signal supplied from a third selection signal line SSL3, and a gate electrode of the fourth transistor T4 may be turned on or off in response to a selection signal supplied from a fourth selection signal line SSL4. In this case, the selection signal supplied from the third selection signal line SSL3 and the selection signal supplied from the fourth selection signal line SSL4 may be the first selection signal Ss and the second selection signal Ps, respectively, which are Fig. 3 and Fig. 4. However, the present disclosure is not limited thereto.

[0214] 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. Substantially identical or similar to the embodiment described with reference to Fig. 3 and Fig. 4, the third light-emitting element ED3 of the second pixel PX2 can be connected between the third transistor T3 and the second power line configured to provide the second supply voltage VSS, and the fourth light-emitting element ED4 of the second pixel PX2 can be connected between the fourth transistor T4 and the second power line configured to provide the second supply voltage VSS. For example, the third light-emitting element ED3 and the fourth light-emitting element ED4 can be Fig. 9A light-emitting elements corresponding respectively to the first type light-emitting element EDa and the second type light-emitting element EDb, which are shown with reference to the Fig. 3 and Fig. 4 are described.

[0215] Therefore, when the third transistor T3 is turned on in response to the selection signal at a turn-on level provided from the third selection signal line SSL3, the first drive current flowing through the third light-emitting element ED3 can be formed so that the third light-emitting element ED3 of the second pixel PX2 can emit light.

[0216] In addition, when the fourth transistor T4 is turned on in response to the selection signal at a turn-on level provided from the fourth selection signal line SSL4, the second drive current flowing through the fourth light-emitting element ED4 can be formed so that the fourth light-emitting element ED4 of the second pixel PX2 can emit light.

[0217] The second pixel PX2 can operate in the first state, in which the third light-emitting element ED3 emits light. Alternatively, the second pixel PX2 can operate in the second state, in which the fourth light-emitting element ED4 emits light.

[0218] The second pixel PX2 may include a third lens LS3 arranged above the third light-emitting element ED3 and a fourth lens LS4 arranged above the fourth light-emitting element ED4.

[0219] With reference to Fig. 9B to describe the third lens LS3 and the fourth lens LS4 in more detail, 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 positioned, respectively.

[0220] The third lens area LSA3 and the fourth lens area LSA4 can provide images with different viewing angles. The brightness of the third lens area LSA3 can be controlled by the first drive current generated by the third light-emitting element ED3, and the brightness of the fourth lens area LSA4 can be controlled by the second drive current generated by the fourth light-emitting element ED4.

[0221] The third lens LS3 can be positioned over the third light-emitting element ED3, and the fourth lens LS4 can be positioned over the fourth light-emitting element ED4.

[0222] The third lens LS3 may have a first shape. The third lens LS3 may have a shape in which at least light in one direction is not restricted. For example, a planar shape of the third lens LS3 positioned in the second pixel PX2 may be a bar shape extending in one direction. For example, the third lens LS3 may be implemented as the first type lens 161 described with reference to Fig. 6 is described.

[0223] In this case, if the light generated by the third light-emitting element ED3 of the second pixel PX2 is emitted through the third lens LS3, the propagation direction of the corresponding light may not be limited to one direction.

[0224] The fourth lens LS4 may have a second shape. The fourth lens LS4 may restrict the propagation direction in which the light passes through the second-type lens 162 to one direction and / or another direction. For example, a planar shape of the fourth lens LS4 positioned in the second pixel PX2 may be a circular shape, but the present disclosure is not limited thereto. For example, the fourth lens LS4 may be implemented as the second-type lens 162 described with reference to Fig. 7 is described.

[0225] In this case, if the light generated by the fourth light-emitting element ED4 of the second pixel PX2 is emitted through the fourth lens LS4, the propagation direction of the corresponding light may be limited to one direction and / or another direction.

[0226] A third light-emitting region 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 a fourth light-emitting region EA4 defined by the fourth light-emitting element ED4 of the second pixel PX2 may have a shape corresponding to the fourth lens LS4.

[0227] For example, as in Fig. 9B, a planar shape of the third light-emitting region EA3 may be a bar shape extending in a direction to correspond to the shape of the third lens LS3. Furthermore, in this case, the third lens LS3 positioned in the third lens region LSA3 may be larger than the third light-emitting region EA3 included in the third lens region LSA3. Therefore, it is possible to improve the efficiency of the light emitted from the third light-emitting region EA3 of the second pixel PX2.

[0228] In addition, as in Fig. 9B illustrates, a planar shape of the fourth light-emitting region EA4 may be a circular shape corresponding to the shape of the fourth lens LS4. In addition, in this case, the fourth lens LS4 positioned in the fourth lens region LSA4 may have a larger size than the fourth light-emitting region EA4 included in the fourth lens region LSA4. For example, a planar shape of the fourth light-emitting region EA4 positioned in the fourth lens region LSA4 may have a circular shape concentric with the planar shape of the fourth lens LS4 positioned in the fourth lens region LSA4. In this case, it is possible to improve the efficiency of the light emitted from the fourth light-emitting region EA4 of the second pixel PX2.

[0229] Since the third lens LS3 is implemented as a lens of the first type 161, the third lens region LSA3 may include a third light-emitting region EA3 and a third lens LS3, as described with reference to Fig. 6. Since the fourth lens LS4 is implemented as a lens of the second type 162, the fourth lens region LSA4 may also include the two fourth light-emitting regions EA4 and the two fourth lenses LS4, as described with reference to Fig. 7 described.

[0230] Therefore, in the case where the first drive current is generated 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 a third pixel PX3 is emitted through the third lens LS3 implemented as a first-type lens 161. Therefore, the content provided by the light generated by the third light-emitting element ED3 of the second pixel PX2 can be provided at the first viewing angle. For example, the provided content (or images) can be shared with people located adjacent to the user in a direction. Therefore, the content provided by the light emitted by the third lens LS3 can be provided in the wide field of view mode (shared mode).

[0231] In addition, in the case where the second drive current is generated 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 as a second-type lens 162. Therefore, the content provided by the light generated by the fourth light-emitting element ED4 of the second pixel PX2 can be provided at the second viewing angle. For example, the provided content (or images) cannot be shared with people adjacent to the user. Therefore, the content provided by the light emitted by the fourth lens LS4 can be provided in the narrow field of view mode (private mode).

[0232] In this case, as described above, the second pixel PX2 can operate in the first state in which the third light-emitting element ED3 emits light. Alternatively, the second pixel PX2 can operate in the second state in which the fourth light-emitting element ED4 emits light. Therefore, when the second pixel PX2 operates in the first state, the content in the first viewing angle can be provided by the light generated by the third light-emitting element ED3. When the second pixel PX2 operates in the second state, the content in the second viewing angle can be provided by the light generated by the fourth light-emitting element ED4.

[0233] As described above, the second area in which the second pixel PX2 operating in the first or second state is arranged among the plurality of areas of the display panel PN can provide the content in the wide field of view mode or the content in the narrow field of view mode according to the driving mode.

[0234] Fig. 10 is a view illustrating an example of the display panel of the display device according to the embodiment of the present specification. Fig. 11 is a plan view schematically illustrating an arrangement of the lenses of the first and second pixels used in the display panel in Fig. 10 are included.

[0235] Meanwhile, Fig. 10 shows an example of the display panel PN including first and second areas A1 and A2 included in the display device 100 according to the embodiment of the present description described with reference to Fig. 2 is described. Fig. Fig. 11 illustrates an example of the first pixel PX1 arranged in the first area A1 and an example of the second pixel PX2 arranged in the second area A2 of the display panel PN in Fig. 10 is arranged.

[0236] Meanwhile, Fig. 11 an embodiment in which the first pixel PX1 and the second pixel PX2 each contain three subpixels.

[0237] Meanwhile, the Fig. 10 and Fig. 11, for convenience of description, a first direction DR1 is shown as a horizontal direction in a plan view and a second direction DR2 is shown as a vertical direction in a plan view.

[0238] Meanwhile, Fig. 10, for convenience of description, a plurality of rows R1 and R2 defined in a direction parallel to the first direction DR1 and a plurality of columns C1 to Cm defined in a direction parallel to the second direction DR2 are designated as a plurality of pixel rows and a plurality of pixel columns in which the plurality of first pixels PX1 are arranged in the first area A1.

[0239] With reference to the Fig. 2 and 6 to 10, the display panel PN can be divided into the plurality of areas A1 and A2. For example, the display panel PN, as in Fig. 10, may be divided into two regions A1 and A2. For example, the display panel PN may include the first region A1 and the second region A2 adjacent to the first region A1 in a direction opposite to the first direction DR1.

[0240] The regions A1 and A2 included in the display panel PN may include a plurality of pixels in which pixel circuits are arranged. For example, the plurality of first pixels PX1 may be arranged in the first region A1 and spaced apart from each other in the first direction DR1 and the second direction DR2, and the plurality of second pixels PX2 may be arranged in the second region A2 and spaced apart from each other in the first direction DR1 and the second direction DR2.

[0241] Meanwhile, as described above, the first area A1 of the display panel PN may be an area arranged on the side of the driver's seat provided in the front seat of the vehicle described with reference to Fig. 1, for example, an area providing the content in the wide field of view mode. The second area A2 of the display panel PN may be an area provided on the side of the passenger seat provided in the front seat of the vehicle described with reference to Fig. 1, for example, an area providing the content in the wide field of view mode or the content in the narrow field of view mode according to the driving mode of the display device 100.

[0242] For example, the plurality of first pixels PX1 arranged in the first area A1 may display images through the first lens area LSA1 and the second lens area LSA2. For example, the plurality of first pixels PX1 arranged in the first area A1 may each operate in the third state in which both the first lens area LSA1 and the second lens area LSA2 display images, for example, in each of the first and second modes, regardless of the driving mode.

[0243] In addition, as with reference to the Fig. 8A and Fig. 8B, both the first lens LS1 positioned in the first lens area LSA1 and the second lens LS2 positioned in the second lens area LSA2 emit (provide) light at the first viewing angle from each of the plurality of first pixels PX1 arranged in the first area A1. Therefore, the images displayed by the plurality of first pixels PX1 arranged in the first area A1 can be provided to the user in each of the first and second modes at the first viewing angle.

[0244] The plurality of second pixels PX2 arranged in the second area A2 can display images through the third lens area LSA3 and the fourth lens area LSA4. For example, the plurality of second pixels PX2 arranged in the second area A2 can each operate in the first state in which only the third lens area LSA3 displays images in the first mode. Alternatively, the plurality of second pixels PX2 arranged in the second area A2 can each operate in the second state in which only the fourth lens area LSA4 displays images in the second mode.

[0245] In addition, as with reference to the Fig. 9A and Fig. 9B, the third lens LS3 arranged in the third lens area LSA3 of each of the plurality of second pixels PX2 arranged in the second area A2 provides the light at the first viewing angle. Therefore, in the first mode, the images displayed by the plurality of second pixels PX2 arranged in the second area A2 can be provided to the user at the first viewing angle. In addition, the fourth lens LS4 arranged in the fourth lens area LSA4 of each of the plurality of second pixels PX2 arranged in the second area A2 can provide the light at the second viewing angle. Therefore, in the second mode, the images displayed by the plurality of second pixels PX2 arranged in the second area A2 can be provided to the user at the second viewing angle.

[0246] Meanwhile, as described above, the first pixel PX1 arranged in the first area A1 and the second pixel PX2 arranged in the second area A2 have different lens arrangement structures, which may cause a problem that a boundary between the first area A1 and the second area A2 is visually recognized.

[0247] With reference to Fig. 11 To describe this situation in more detail, the first pixel PX1 may include a first red subpixel RSP1 configured to implement red, a first green subpixel GSP1 configured to implement green, and a first blue subpixel BSP1 configured to implement blue, and the second pixel PX2 may include a second red subpixel RSP2 configured to implement red, a second green subpixel GSP2 configured to implement green, and a second blue subpixel BSP2 configured to implement blue.

[0248] Meanwhile, the first pixel PX1 and the second pixel PX2, illustrated in Fig. 11, is provided for illustrative purposes only, and the embodiment of the present description is not limited thereto. For example, the first pixel PX1 and / or the second pixel PX2 may each additionally include a subpixel to implement a particular color in addition to red, green, and blue, e.g., white.

[0249] The first pixel PX1 and the second pixel PX2 may have substantially the same subpixel arrangement structure. For example, the first pixel PX1 may have a subpixel arrangement structure 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 based on the first direction DR1. Similarly, the second pixel PX2 may have a subpixel arrangement structure 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 based on the first direction DR1. However, this is for illustrative purposes only, and the subpixel arrangement structures 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 each have an arrangement structure different from that shown in . Fig. 11, and / or the first pixel PX1 and the second pixel PX2 may have different subpixel arrangement structures.

[0250] The first pixel PX1 may include the plurality of first lens areas LSA1 in which the first lenses LS1 are arranged for each subpixel, and the plurality of second lens areas LSA2 in which the second lenses LS2 are arranged for each subpixel.

[0251] For example, the first red sub-pixel RSP1 of the first pixel PX1 may include a first sub-lens area LSA1a in which the first lens LS1 is arranged and a second sub-lens area LSA2a in which the second lens LS2 is arranged, the first green sub-pixel GSP1 of the first pixel PX1 may include a third sub-lens area LSA1b in which the first lens LS1 is arranged and a fourth sub-lens area LSA2b in which the second lens LS2 is arranged, and the first blue sub-pixel BSP1 of the first pixel PX1 may include a fifth sub-lens area LSA1c in which the first lens LS1 is arranged and a sixth sub-lens area LSA2c in which the second lens LS2 is arranged.

[0252] In this case, the first sub-lens region LSA1a, the third sub-lens region LSA1b, and the fifth sub-lens region LSA1c in which the first lenses LS1 of the first pixel PX1 are arranged may be regions arranged in the first lens region LSA1. For example, the first lenses LS1 each having the first shape are arranged in the first sub-lens region LSA1a, the third sub-lens region LSA1b, and the fifth sub-lens region LSA1c of the first pixel PX1, so that images obtained from the first sub-lens region LSA1a, the third sub-lens region LSA1b, and the fifth sub-lens region LSA1c of the first pixel PX1 can be provided to the user at the first viewing angle.

[0253] Additionally, the second sub-lens region LSA2a, the fourth sub-lens region LSA2b, and the sixth sub-lens region LSA2c in which the second lenses LS2 of the first pixel PX1 are arranged may be regions included in the second lens region LSA2. For example, the second lenses LS2 each having the first shape are arranged in the second sub-lens region LSA2a, the fourth sub-lens region LSA2b, and the sixth sub-lens region LSA2c of the first pixel PX1, so that images obtained 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 can be provided to the user at the first viewing angle.

[0254] For example, the first to sixth sub-lens areas LSA1a, LSA2a, LSA1b, LSA2b, LSA1c and LSA2c of the first pixel PX1 can provide images at the same viewing angle.

[0255] The second pixel PX2 may include the plurality of third lens areas LSA3 in which the third lenses LS3 are arranged for each subpixel, and the plurality of fourth lens areas LSA4 in which the fourth lenses LS4 are arranged for each subpixel.

[0256] For example, the second red sub-pixel RSP2 of the second pixel PX2 may include a seventh sub-lens area LSA3a in which the third lens LS3 is arranged, and an eighth sub-lens area LSA4a in which the fourth lens LS4 is arranged, the second green sub-pixel GSP2 of the second pixel PX2 may include a ninth sub-lens area LSA3b in which the third lens LS3 is arranged, and a tenth sub-lens area LSA4b in which the fourth lens LS4 is arranged, and the second blue sub-pixel BSP2 of the second pixel PX2 may include an eleventh sub-lens area LSA3c in which the third lens LS3 is arranged, and a twelfth sub-lens area LSA4c in which the fourth lens LS4 is arranged.

[0257] In this case, the seventh sub-lens region LSA3a, the ninth sub-lens region LSA3b, and the eleventh sub-lens region LSA3c in which the third lenses LS3 of the second pixel PX2 are arranged may be regions included in the third lens region LSA3. For example, the third lenses LS3 each having the first shape may be arranged in the seventh sub-lens region LSA3a, the ninth sub-lens region LSA3b, and the eleventh sub-lens region LSA3c of the second pixel PX2, so that images displayed by the seventh sub-lens region LSA3a, the ninth sub-lens region LSA3b, and the eleventh sub-lens region LSA3c of the second pixel PX2 can be provided to the user at the first viewing angle.

[0258] Additionally, the eighth sub-lens region LSA4a, the tenth sub-lens region LSA4b, and the twelfth sub-lens region LSA4c in which the fourth lenses LS4 of the second pixel PX2 are arranged may be regions included in the fourth lens region LSA4. For example, the fourth lenses LS4 each having the second shape may be arranged in the eighth sub-lens region LSA4a, the tenth sub-lens region LSA4b, and the twelfth sub-lens region LSA4c of the second pixel PX2, so that images displayed by the eighth sub-lens region LSA4a, the tenth sub-lens region LSA4b, and the twelfth sub-lens region LSA4c of the sub-lens of the second pixel PX2 can be provided to the user at the second viewing angle.

[0259] For example, the seventh lens area LSA3a, the ninth lens area LSA3b and the eleventh lens area LSA3c in which the third lenses LS3 of the second pixel PX2 are arranged, and the eighth lens area LSA4a, the tenth lens area LSA4b and the twelfth lens area LSA4c in which the fourth lenses LS4 are arranged can provide images with different viewing angles.

[0260] The arrangement structures of the first lens region LSA1 and the second lens region LSA2 of the first pixel PX1 may be substantially identical to the arrangement structures of the third lens region LSA3 and the fourth lens region LSA4 of the second pixel PX2.

[0261] For example, the first lens areas LSA1 of the first pixel PX1, e.g., 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 respectively to the third lens areas LSA3, e.g., the seventh sub-lens area LSA3a, the ninth sub-lens area LSA3b, and the eleventh sub-lens area LSA3c, in which the third lenses LS3 of the first-type lenses 161 are arranged in the second pixel PX2.

[0262] In addition, the second lens areas LSA2 of the first pixel PX1, e.g., 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 respectively to the fourth lens areas LSA4, e.g., the eighth sub-lens area LSA4a, the tenth sub-lens area LSA4b, and the twelfth sub-lens area LSA4c, in which the fourth lenses LS4 of the second-type lenses 162 are arranged in the second pixel PX2.

[0263] The number of fourth lenses LS4 arranged in the fourth lens region LSA4 and the number of light-emitting regions corresponding to the fourth lenses LS4 may vary depending on each of the subpixels RSP2, GSP2, and BSP2 of the second pixel PX2. For example, the number of fourth lenses LS4 positioned in the tenth sub-lens region LSA4b of the second green subpixel GSP2 and the number of fourth lenses LS4 positioned in the twelfth sub-lens region LSA4c of the second blue subpixel BSP2 may be greater than the number of fourth lenses LS4 positioned in the eighth sub-lens region LSA4a of the second red subpixel RSP2.In this case, a deviation in the efficiency of the fourth light-emitting element ED4 positioned in the fourth lens region LSA4 of the second pixel PX2 can be compensated by the number of fourth lenses LS4 arranged in the fourth lens region LSA4 of the second pixel PX2 and the number of light-emitting regions corresponding to the fourth lenses LS4. However, the number of fourth lenses LS4 arranged in the fourth lens region LSA4 and the number of light-emitting regions corresponding to the fourth lenses LS4 for each of the subpixels RSP2, GSP2, and BSP2 of the second pixel PX2 are not limited thereto. According to the embodiment, the number of fourth lenses LS4 arranged in the fourth lens region LSA4 and the number of light-emitting regions corresponding to the fourth lenses LS4 for each of the subpixels RSP2, GSP2, and BSP2 of the second pixel PX2 may be the same.

[0264] As described above, 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, the lenses having the first shape, e.g., the first lens LS1 and the second lens LS2, may be arranged in all of the lens regions LSA1 and LSA2. In contrast, in the case of the second pixel PX2, the third lens LS3 having the first shape may be arranged in the third lens region LSA3, and the fourth lens LS4 having the second shape may be arranged in the fourth lens region LSA4.

[0265] Therefore, in the case where the plurality of first pixels PX1 arranged in the first area A1 and the plurality of second pixels PX2 arranged in the second area A2 display images having the same brightness, there may be a problem that the boundary between the first area A1 and the second area A2 is visually recognized due to a difference in the lens arrangement structures between the first pixel PX1 and the second pixel PX2.

[0266] Specifically, as described above, if the display device 100 operates in the first mode, the plurality of first pixels PX1 in the first area A1 can operate in the third state and display images through the first lens area LSA1 and the second lens area LSA2, while the plurality of second pixels PX2 in the second area A2 can operate in the first state and display images only through the third lens area LSA3. In this case, both the first area A1 and the second area A2 provide images at the first viewing angle to the user in the first mode, so that images can be provided to the user in a form in which the images displayed in the first area A1 and the images displayed in the second area A2 are continuously arranged.In this case, if the plurality of first pixels PX1 arranged in the first area A1 and the plurality of second pixels PX2 arranged in the second area A2 display images with the same brightness, the plurality of first pixels PX1 in the first area A1 operate in the third state and display images through the first lens area LSA1 and the second lens area LSA2, thereby implementing high brightness of the first area A1 compared to the second area A2 operating in the first state and displaying images only through the third lens area LSA3. A problem may occur in that the boundary between the first area A1 and the second area A2 is visually recognized due to the above-mentioned difference in brightness.

[0267] To solve or mitigate the above-mentioned problem, the display device 100 according to the embodiment of the present description may 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 control means LD may generate the 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 control means TD may generate the image data RGB to be supplied to the data driving circuit DD based on the corrected image data CDATA, thereby controlling the brightness of the images to be displayed on the display panel PN.

[0268] The display device 100, e.g., the brightness control device LD, can control the brightness of the display panel PN, e.g., the first area A1, such that the brightness of the first area A1 increases with increasing distance from the boundary between the first area A1 and the second area A2. Additionally, the brightness control device LD can control the brightness of the area of the first area A1 adjacent to the boundary between the first area A1 and the second area A2 to have a value substantially equal to or similar to the brightness of the second area A2.In the first mode in which images in the first viewing angle are provided in both the first area A1 and the second area A2, a difference in brightness between the first area A1 and the second area A2 at the boundary between the first area A1 and the second area A2 can be minimized or reduced by the operation of the brightness control means LD, whereby the problem in which the boundary between the first area A1 and the second area A2 is visually recognized can be solved or alleviated.

[0269] Hereinafter, a configuration in which the display device 100, e.g., the brightness control means LD, controls the brightness of the first area A1 will be described with reference to FIG. Fig. 12 to 18. As described above, the brightness control device LD can control the brightness of the first area A1 by generating the corrected image data CDATA based on the input image data IDATA. However, the configuration in which the brightness control device LD controls the brightness of the first area A1 is not limited thereto.

[0270] Fig. 12 is a view for explaining an example in which the display device according to the embodiment of the present specification operates in the first mode. Fig. 13 is a view for explaining an example in which the display device according to the embodiment of the present specification operates in the second mode.

[0271] Meanwhile, the Fig. 12 and Fig. 13 shows an example of the display panel PN in the case where the display device 100 according to the embodiment of the present description operates in the first and second modes.

[0272] Meanwhile, the Fig. 12 and Fig. 13 For convenience of description, “Off” indicates that the light-emitting element arranged in the lens area on the display panel PN does not emit light.

[0273] With reference to the Fig. 2 to 11, the mode control unit MS included in the display device 100 may generate the mode selection signal MSS based on the externally input mode signal MODE. For example, the mode control unit MS may receive the mode signal MODE from the outside in response to the drive mode of the display device 100, generate the mode selection signal MSS based on the mode signal MODE, and supply the mode selection signal MSS to the mode selection part MD. In addition, in response to the mode selection signal MSS provided by the mode control unit MS, the mode selection part MD may supply the selection signals corresponding to the drive mode to the plurality of pixels PX, for example, to the plurality of first pixels PX1 arranged in the first area A1 and to the plurality of second pixels PX2 arranged in the second area A2.

[0274] If the display device 100 operates in the first mode, the second area A2 of the display panel PN may provide the user with the content at the first viewing angle in response to the selection signal provided by the mode selection part MD.

[0275] In particular, with reference to Fig. 12 each of the plurality of second pixels PX2 arranged in the second area A2 operates in the first mode in the first state.

[0276] For example, in the first mode, when the third transistor T3 included in the second pixel PX2 is turned on in response to the selection signal provided via the third selection signal line SSL3, the first drive current is formed in the second pixel PX2, and the light emitted by the first drive current from the third light-emitting element ED3 arranged in the third lens region LSA3 of the second pixel PX2 is emitted through the third lens LS3 arranged in the third lens region LSA3 and configured as the first type lens 161, so that the content with the first viewing angle can be provided.

[0277] Meanwhile, in the first mode, the selection signal maintained at a cutoff level is supplied to the fourth selection signal line SSL4, and the fourth transistor T4 included in the second pixel PX2 is maintained in a cutoff state, so that the fourth light-emitting element ED4 disposed in the fourth lens region LSA4 of the second pixel PX2 can be maintained in a non-light-emitting state. For example, in the second mode, the current path for the second drive current cannot be formed in the second pixel PX2.

[0278] In addition, if the display device 100 operates in the second mode, the second area A2 of the display panel PN may provide the user with the content at the second viewing angle in response to the selection signal provided by the mode selection part MD.

[0279] In particular, with reference to Fig. 13 each of the plurality of second pixels PX2 arranged in the second area A2 operates in the second mode in the second state.

[0280] For example, in the second mode, when the fourth transistor T4 included in the second pixel PX2 is turned on in response to the selection signal provided via the fourth selection signal line SSL4, the second drive current is formed in the second pixel PX2, and the light emitted by the second drive current from the fourth light-emitting element ED4 arranged in the fourth lens region LSA4 of the second pixel PX2 is emitted through the fourth lens LS4 arranged in the fourth lens region LSA4 and configured as the second type lens 162, so that the content with the second viewing angle can be provided.

[0281] Meanwhile, in the second mode, the selection signal maintained at a cutoff level is supplied to the third selection signal line SSL3, and the third transistor T3 included in the second pixel PX2 is maintained in a cutoff state, so that the third light-emitting element ED3 of the second pixel PX2 can be maintained in a non-light-emitting state. For example, in the second mode, the current path of the first drive current cannot be formed in the second pixel PX2.

[0282] Therefore, when the display device 100 operates in the first mode, the second area A2 of the display panel PN provides the content to the user at the first viewing angle. When the display device 100 operates in the second mode, the second area A2 of the display panel PN can provide the content to the user at the second viewing angle.

[0283] The display device 100 can control the brightness of the second area A2 to correspond to the input image data IDATA regardless of the control mode. For example, the brightness control device LD can generate the corrected image data CDATA such that the values of the corrected image data CDATA corresponding to the second area A2 are equal to the values of the input image data IDATA.

[0284] Therefore, in each of the first mode in which the content is provided to the user with the first viewing angle and the second mode in which the content is provided to the user with the second viewing angle, the second pixel PX2 located in the second area A2 can display images with a brightness (hereinafter referred to as “reference brightness L0”) corresponding to the input image data IDATA. For example, as shown in Fig. 12 illustrates, in the first mode, the third lens area LSA3 of each of the plurality of second pixels PX2 emits light with the reference brightness L0. As shown in Fig. 13, in the second mode, the fourth lens area LSA4 of each of the plurality of second pixels PX2 can emit light having the reference brightness L0.

[0285] As described above, in both the first mode in which the content is provided in the wide field of view mode and the second mode in which the content is provided in the narrow field of view mode, the display device may operate such that the first area A1 of the display panel PN provides the content in the first viewing angle.

[0286] For example, if the display device 100 operates in the first or second mode, the first area A1 of the display panel PN may provide the user with the content at the first viewing angle in response to the selection signal provided by the mode selection part MD.

[0287] In particular, with reference to the Fig. 12 and Fig. 13 in each of the first and second modes, each of the plurality of first pixels PX1 arranged in the first area A1 operates in the third state.

[0288] For example, in each of the first and second modes, the first drive current may be formed in the first pixel PX1 when the first transistor T1 included in the first pixel PX1 is turned on in response to the selection signal provided via the first selection signal line SSL1, and the second drive current may be formed in the first pixel PX1 when the second transistor T2 included in the first pixel PX1 is turned on in response to the selection signal provided via the second selection signal line SSL2.In addition, the light emitted by the first driving current from the first light-emitting element ED1 arranged in the first lens region LSA1 of the first pixel PX1 is emitted through the first lens LS1 arranged in the first lens region LSA1 and configured as the first type lens 161, and the light emitted by the second driving current from the second light-emitting element ED2 arranged in the second lens region LSA2 of the first pixel PX1 is emitted through the second lens LS2 arranged in the second lens region LSA2 and configured as the first type lens 161, so that the content can be provided with the first viewing angle.

[0289] In the first mode, the display device 100 may control the brightness of the display panel PN, e.g., the first region A1, such that the brightness of the first region A1 increases as the distance from the boundary between the first region A1 and the second region A2 increases. For example, in the first mode, the display device 100 may perform control such that the brightness of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 increases as the distance from the boundary between the first region A1 and the second region A2 increases.

[0290] In addition, the display device 100 may control such that the brightness of the portion of the first region A1 adjacent to the boundary between the first region A1 and the second region A2 has a value substantially equal to or similar to that of the brightness of the second region A2.

[0291] With reference to Fig. 12 to describe the present disclosure in more detail, in the first mode, the display device 100 may perform control such that the brightness of the first lens area LSA1 of the first pixel PX1 located in the first area A1 corresponds to the input image data IDATA. For example, the brightness controller LD may generate the corrected image data CDATA such that the values of the corrected image data CDATA corresponding to the first lens area LSA1 of each of the plurality of first pixels PX1 located in the first area A1 are equal to the values of the input image data IDATA. Therefore, in the first mode, the first lens area LSA1 of the first pixel PX1 located in the first area A1 may emit light at the reference brightness L0.

[0292] In addition, in the first mode, the brightness of the second lens area LSA2 of the first pixel PX1 arranged in the first area A1 may increase with increasing distance from the boundary between the first area A1 and the second area A2.

[0293] For example, the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in a first column C1 closest to the boundary between the first area A1 and the second area A2 may emit light having a first brightness L1 lower than the reference brightness L0.

[0294] In addition, the second lens region LSA2 of each of the plurality of first pixels PX1, which is provided in the first region A1 and arranged in a second column C2 adjacent to the first column C1 in the first direction DR1, may emit light with a second brightness L2 greater than the first brightness L1. In this case, the second brightness L2 may be smaller than the reference brightness L0.

[0295] Similarly, the second lens region LSA2 of each of the plurality of first pixels PX1, provided in the first region A1 and arranged in a third column C3 adjacent to the second column C2 in the first direction DR1, may emit light having a third brightness L3 higher than the second brightness L2. In this case, the third brightness L3 may be lower than the reference brightness L0.

[0296] Similarly, the second lens region LSA2 of each of the plurality of first pixels PX1, provided in the first region A1 and arranged in a fourth column C4 adjacent to the third column C3 in the first direction DR1, may emit light with a fourth brightness L4 higher than the third brightness L3. In this case, the fourth brightness L4 may be lower than the reference brightness L0.

[0297] Similarly, the second lens region LSA2 of each of the plurality of first pixels PX1 provided in the first region A1 and arranged in an (m-1)th column Cm-1 adjacent to an mth (here, m is an integer greater than 0) column Cm farthest from the boundary between the first region A1 and the second region A2 in a direction opposite to the first direction DR1 may emit light having a fifth brightness L5 higher than the fourth brightness L4. In this case, the fifth brightness L5 may be lower than the reference brightness L0.

[0298] In addition, the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and located in the m-th column Cm farthest from the boundary between the first area A1 and the second area A2 may emit light at the reference brightness L0. For example, the display device 100 may control such that the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the pixel column, e.g., the m-th column Cm farthest from the boundary between the first area A1 and the second area A2, of the plurality of first pixels PX1 arranged in the first area A1, corresponds to the input image data IDATA.

[0299] As described above, in the first mode, the display device 100 can perform control such that the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first area A1 increases in the first direction DR1, that is, increases as the distance from the boundary between the first area A1 and the second area A2 increases. For example, the display device 100 can be controlled such that the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first area A1 increases from the first column C1 to the m-th column Cm. Therefore, it is possible to minimize or mitigate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized when displaying images in the first mode.

[0300] The first brightness L1 of the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 may be a brightness substantially corresponding to a black image. For example, the first brightness L1 may have a value of 0.In this case, the brightness of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 may correspond to a value formed by adding the reference brightness L0 of the first lens area LSA1 and the first brightness L1 of the second lens area LSA2, so that the brightness of each of the plurality of first pixels P X1 arranged in the first column C1 may have a value substantially equal to or similar to that of the reference brightness L0.

[0301] Therefore, the brightness of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 can have a value substantially equal to or similar to the brightness, e.g., the reference brightness L0, of each of the plurality of second pixels PX2 arranged in the second area A2. Therefore, it is possible to more effectively solve or mitigate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized when displaying images in the first mode.

[0302] However, the embodiment of the present description is not limited to this. The second lens region LSA2 of each of the plurality of first pixels PX1, which is provided in the first region A1 and located in the first column C1 closest to the boundary between the first region A1 and the second region A2, may not emit light.

[0303] In addition, as with reference to Fig. As described in Figure 11, the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first area A1 may be arranged at a position corresponding in the lens arrangement structure to the fourth lens area LSA4 in which the fourth lenses LS4 of the second-type lenses 162 are arranged in the plurality of second pixels PX2 arranged in the second area A2. Therefore, in the first mode, the display device 100 performs control so that the brightness of the plurality of first pixels PX1 arranged in the first area A1 increases in the first direction DR1, e.g.increases as the distance from the boundary between the first area A1 and the second area A2 increases, the display device 100 controls the brightness of the second lens area LSA2 of the first pixel PX1, which in the lens array structure corresponds to the fourth lens area LSA4 of the second area A2 that does not emit light in the first mode, which may more effectively solve or alleviate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized.

[0304] In the first mode, the display device 100 can control the brightness of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 to increase linearly in the first direction DR1, that is, to increase with increasing distance from the boundary between the first region A1 and the second region A2. Therefore, it is possible to minimize or mitigate a problem in which the change in brightness of the first region A1, e.g., the change in brightness in the first direction DR1, is visually recognized by the user.

[0305] Meanwhile, as described above, in the second mode, the display device 100 may perform control so that the brightness of the first area A1 corresponds to the input image data IDATA.

[0306] For example, the display device 100 may be described with reference to Fig. 13 in the second mode so that the brightness of the first lens area LSA1 of the first pixel PX1 arranged in the first area A1 and the brightness of the second lens area LSA2 correspond to the input image data IDATA. For example, the brightness control means LD may generate the corrected image data CDATA so that the values 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 in the first area A1 are equal to the values of the input image data IDATA. Therefore, in the second mode, the first lens area LSA1 of the first pixel PX1 arranged in the first area A1 can emit light at the reference brightness L0, and the second lens area LSA2 of the first pixel PX1 arranged in the first area A1 can emit light at the reference brightness L0.

[0307] Meanwhile, as described above, in the second mode, both the first lens area LSA1 and the second lens area LSA2 of the first pixel PX1 located in the first area A1 emit light at the reference brightness L0, which may result in a difference in brightness between the image displayed in the first area A1 and the image displayed in the second area A2. However, despite the difference in brightness, in the second mode, the image is displayed in the first area A1 at the first viewing angle and in the second area A2 at the second viewing angle, so the problem in which the boundary is essentially visually discernible to the user does not occur.

[0308] As described above, the display device 100 according to the embodiment of the present description can display the content in the first mode at the first viewing angle on the display panel PN according to the driving mode, and display the content in the second mode at the second viewing angle in at least a partial area (second area) of the display panel PN. In this case, the display device 100 according to the embodiment of the present description can control the brightness of the first area A1 of the display panel PN according to the driving mode, so that the brightness of the first area A1 increases as the distance from the boundary between the first area A1 and the second area A2, which provide the content in the first mode at the first viewing angle, increases.In addition, the display device 100 may control such that the brightness of the portion of the first region A1 adjacent to the boundary between the first region A1 and the second region A2 has a value substantially equal to or similar to that of the brightness of the second region A2.

[0309] Therefore, it is possible to solve or mitigate the problem of visually detecting the boundary between the first area A1 and the second area A2.

[0310] Meanwhile, the configuration in which, in the first mode, the display device 100 controls the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first area A1 and controls the brightness of the plurality of first pixels PX1 arranged in the entire first area A1 has been described above. However, the embodiment of the present description is not limited to this.

[0311] Therefore, various embodiments of the present description will be described in more detail below, in which the display device 100 controls the brightness of the first area A1 in the first mode.

[0312] Fig. 14 is a view for explaining another example in which the display device according to the embodiment of the present specification operates in the first mode.

[0313] Fig. 14 illustrates an embodiment in which the display device 100 controls the brightness of a partial area, e.g., a third area A3 of the first area A1 in the first mode.

[0314] Meanwhile, Fig. 14 shows an example of the display panel PN in the case where the display device 100 according to the embodiment of the present description operates in the first mode.

[0315] With reference to Fig. 14, in the first mode, the display device 100 may control the brightness of the display panel PN, e.g., the first region A1, such that the brightness of a sub-region, e.g., the third region A3 of the first region A1, 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 perform control such that the brightness of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the third region A3 increases as the distance from the boundary between the first region A1 and the second region A2 in the third region A3 of the first region A1 adjacent to the second region A2 increases.

[0316] In addition, the display device 100 may control such that the brightness of the portion of the third region A3 adjacent to the boundary between the first region A1 and the second region A2 has a value substantially equal to or similar to that of the brightness of the second region A2.

[0317] Therefore, in the first mode, the brightness of the first pixel PX1 located in the third area A3 of the first area A1 adjacent to the second area A2 may have a value substantially equal to that of the brightness of the second area A2 at a part closest to the second area A2 and increase with increasing distance from the boundary between the first area A1 and the second area A2.

[0318] For example, the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the third area A3 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 may emit light having a sixth brightness L6 lower than the reference brightness L0.

[0319] In addition, the second lens region LSA2 of each of the plurality of first pixels PX1 provided in the third region A3 and arranged in the second column C2 adjacent to the first column C1 in the first direction DR1 may emit light having a seventh brightness L7 higher than the sixth brightness L6. In this case, the seventh brightness L7 may be lower than the reference brightness L0.

[0320] Similarly, the second lens region LSA2 of each of the plurality of first pixels PX1 provided in the third area A3 and arranged in the third column C3 adjacent to the second column C2 in the first direction DR1 may emit light with an eighth brightness L8 higher than the seventh brightness L7. In this case, the eighth brightness L8 may be lower than the reference brightness L0.

[0321] In addition, the second lens area LSA2 of each of the plurality of first pixels PX1 located in the remaining area of the first area A1 excluding the third area A3, e.g., a fourth area A4, may emit light at the reference brightness L0. For example, the display device 100 may control the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 located in the remaining area excluding the third area A3, e.g., the fourth area A4 of the plurality of first pixels PX1 located in the first area A1, to correspond to the input image data IDATA.

[0322] As described above, in the first mode, the display device 100 can control the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the third area A3 of the first area A1 adjacent to the second area A2 to increase in the first direction DR1, that is, to increase as the distance from the boundary between the first area A1 and the second area A2 increases. For example, the display device 100 can control the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the third area A3 to increase from the first column C1 to the third column C3. Therefore, it is possible to minimize or alleviate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized when displaying images in the first mode.

[0323] Substantially identical or similar to that relating to Fig. With the configuration described in FIG. 12, the sixth brightness L6 of the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the third area A3 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 may be the brightness substantially corresponding to a black image. For example, the sixth brightness L6 may have a value of 0. Therefore, it is possible to more effectively solve or mitigate the problem that the boundary between the first area A1 and the second area A2 is visually recognized when displaying images in the first mode. However, the embodiment of the present description is not limited to this.The second lens area LSA2 of each of the plurality of first pixels PX1 provided in the third area A3 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 may not emit light.

[0324] In addition, the display device 100 may be substantially identical or similar to that described with reference to Fig. 12, in the first mode, the display device 100 can be controlled so that the brightness of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the third region A3 increases linearly in the first direction DR1, that is, increases with increasing distance from the boundary between the first region A1 and the second region A2. Therefore, it is possible to minimize or mitigate a problem in which the change in the brightness of the third region A3, for example, the change in the brightness in the first direction DR1, is visually recognized by the user.

[0325] Meanwhile, the configuration in Fig. 14, in which the third region A3 of the first region A1 adjacent to the second region A2 includes the first to third columns C1, C2, and C3, for example, the three pixel columns. However, this configuration is for illustrative purposes only, and the embodiment of the present description is not limited thereto. For example, the third region A3 may be configured to include two or fewer pixel columns, or may be configured to include four or more pixel columns.

[0326] Fig. 15 is a view for explaining another example in which the display device according to the embodiment of the present specification operates in the first mode.

[0327] Fig. 15 illustrates an embodiment in which the display device 100 controls the brightness of the first lens area LSA1 and the second lens area LSA2 of the first pixel PX1 arranged in the first area A1 in the first mode.

[0328] Meanwhile, Fig. 15 shows an example of the display panel PN in the case where the display device 100 according to the embodiment of the present description operates in the first mode.

[0329] With reference to Fig. 15, in the first mode, the display device 100 may control the brightness of the display panel PN, e.g., the first region A1, such that the brightness of the first region A1 increases as the distance from the boundary between the first region A1 and the second region A2 increases. For example, in the first mode, the display device 100 may perform control such that the brightness 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 increases as the distance from the boundary between the first region A1 and the second region A2 increases.

[0330] In addition, the display device 100 may be controlled such that the brightness of the portion of the first region A1 adjacent to the boundary between the first region A1 and the second region A2 has a value substantially equal to or similar to that of the brightness of the second region A2.

[0331] Therefore, in the first mode, the brightness of the first pixel PX1 located in the first area A1 may have a value substantially equal to that of the brightness of the second area A2 at a part closest to the second area A2 and increase with increasing distance from the boundary between the first area A1 and the second area A2.

[0332] For example, the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 may emit light having a ninth brightness L9 lower than the reference brightness L0.

[0333] In addition, the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the second column C2 adjacent to the first column C1 in the first direction DR1 may emit light with a tenth brightness L10 greater than the ninth brightness L9. In this case, the tenth brightness L10 may be lower than the reference brightness L0.

[0334] Similarly, the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the third column C3 adjacent to the second column C2 in the first direction DR1 may emit light with an eleventh brightness L11 higher than the tenth brightness L10. In this case, the eleventh brightness L11 may be lower than the reference brightness L0.

[0335] Similarly, the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the fourth column C4 adjacent to the third column C3 in the first direction DR1 may emit light with a twelfth brightness L12 higher than the eleventh brightness L11. In this case, the twelfth brightness L12 may be lower than the reference brightness L0.

[0336] Similarly, the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 provided in the first region A1 and arranged in the (m-1)th column Cm-1 adjacent to the mth column Cm farthest from the boundary between the first region A1 and the second region A2 in the direction opposite to the first direction DR1 may emit light having a thirteenth brightness L13 higher than the twelfth brightness L12. In this case, the thirteenth brightness L13 may be lower than the reference brightness L0.

[0337] In addition, the first lens area LSA1 and the second lens area LSA2 may emit light at the reference brightness L0 of each of the plurality of first pixels PX1 provided in the first area A1 and located in the m-th column Cm farthest from the boundary between the first area A1 and the second area A2. For example, the display device 100 may control such that the brightness of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the pixel column (e.g., the m-th column Cm) farthest from the boundary between the first area A1 and the second area A2, among the plurality of first pixels PX1 arranged in the first area A1, corresponds to the input image data IDATA.

[0338] As described above, in the first mode, the display device 100 can perform control such that the brightness of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first area A1 increases in the first direction DR1, that is, increases as the distance from the boundary between the first area A1 and the second area A2 increases. For example, the display device 100 can be controlled such that the brightness of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first area A1 increases from the first column C1 to the m-th column Cm. Therefore, it is possible to minimize or mitigate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized when displaying images in the first mode.

[0339] The brightness of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 may be the brightness corresponding to half the reference brightness L0. In this case, the brightness of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 may be a value obtained by adding a value corresponding to half the reference brightness L0, e.g., the ninth brightness L9 of the first lens area LSA1, and a value corresponding to half the reference brightness L0, e.g.,the ninth brightness L9 of the second lens area LSA2, so that the brightness of each of the plurality of first pixels PX1 arranged in the first column C1 can have a value substantially equal to or similar to that of the reference brightness L0.

[0340] Therefore, the brightness of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 can have a value substantially equal to or similar to the brightness, e.g., the reference brightness L0, of each of the plurality of second pixels PX2 arranged in the second area A2. Therefore, it is possible to more effectively solve or mitigate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized when displaying images in the first mode.

[0341] In addition, the display device 100 may be substantially identical or similar to that described with reference to Fig. 12, in the first mode, the display device 100 can be controlled so that the brightness of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first area A1 linearly increases in the first direction DR1, e.g., increases as the distance from the boundary between the first area A1 and the second area A2 increases. Therefore, it is possible to minimize or mitigate a problem in which the change in the brightness of the first area A1, e.g., the change in the brightness in the first direction DR1, is visually recognized by the user.

[0342] Fig. 16 is a view for explaining another example in which the display device according to the embodiment of the present specification operates in the first mode.

[0343] Fig. 16 illustrates an embodiment in which the display device 100 controls the brightness of the first lens area LSA1 and the second lens area LSA2 of the first pixel PX1 arranged in a partial area of the first area A1, e.g., the third area A3, in the first mode.

[0344] Meanwhile, Fig. 16 shows an example of the display panel PN in the case where the display device 100 according to the embodiment of the present description operates in the first mode.

[0345] With reference to Fig. 16, in the first mode, the display device 100 may control the brightness of the display panel PN, e.g., the first region A1, such that the brightness of a sub-region, e.g., the third region A3 of the first region A1, 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 such that the brightness of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the third region A3 increases as the distance from the boundary between the first region A1 and the second region A2 in the third region A3 of the first region A1 adjacent to the second region A2 increases.

[0346] In addition, the display device 100 may control such that the brightness of the portion of the third region A3 adjacent to the boundary between the first region A1 and the second region A2 has a value substantially equal to or similar to that of the brightness of the second region A2.

[0347] Therefore, in the first mode, the brightness of the first pixel PX1 located in the third area A3 of the first area A1 adjacent to the second area A2 may have a value substantially equal to that of the brightness of the second area A2 at a part closest to the second area A2 and increase with increasing distance from the boundary between the first area A1 and the second area A2.

[0348] For example, the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the third area A3 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 may emit light having a fourteenth brightness L14 lower than the reference brightness L0.

[0349] In addition, the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the third area A3 and arranged in the second column C2 adjacent to the first column C1 in the first direction DR1 may emit light with a fifteenth brightness L15 greater than the fourteenth brightness L14. In this case, the fifteenth brightness L15 may be lower than the reference brightness L0.

[0350] Similarly, the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the third area A3 and arranged in the third column C3 adjacent to the second column C2 in the first direction DR1 may emit light with a sixteenth brightness L16 higher than the fifteenth brightness L15. In this case, the sixteenth brightness L16 may be lower than the reference brightness L0.

[0351] In addition, the second lens area LSA2 of each of the plurality of first pixels PX1 located in the remaining area of the first area A1 excluding the third area A3 may emit light at the reference brightness L0. For example, the display device 100 may control the brightness of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 located in the remaining area excluding the third area A3, e.g., the fourth area A4 of the plurality of first pixels PX1 located in the first area A1, to correspond to the input image data IDATA.

[0352] As described above, in the first mode, the display device 100 can control the brightness 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 of the first area A1 adjacent to the second area A2 to increase in the first direction DR1, that is, to increase with increasing distance from the boundary between the first area A1 and the second area A2. For example, the display device 100 can control the brightness 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 increase from the first column C1 to the third column C3. Therefore, it is possible to minimize or mitigate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized when displaying images in the first mode.

[0353] Substantially identical or similar to that relating to Fig. According to the configuration described in Figure 15, the fourteenth brightness L14 of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the third area A3 and arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2 can be the brightness substantially half of the reference brightness L0. Therefore, it is possible to more effectively solve or mitigate the problem that the boundary between the first area A1 and the second area A2 is visually recognized when images are displayed in the first mode.

[0354] In addition, the display device 100 may be substantially identical or similar to that described with reference to Fig. 12, in the first mode, the display device 100 can be controlled so that the brightness 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 increases linearly in the first direction DR1, that is, increases with increasing distance from the boundary between the first area A1 and the second area A2. Therefore, it is possible to minimize or mitigate a problem in which the change in the brightness of the third area A3, for example, the change in the brightness in the first direction DR1, is visually recognized by the user.

[0355] Meanwhile, the configuration in Fig. 16, in which the third region A3 of the first region A1 adjacent to the second region A2 includes the first to third columns C1, C2, and C3, for example, the three pixel columns. However, this configuration is for illustrative purposes only, and the embodiment of the present description is not limited thereto. For example, the third region A3 may be configured to include two or fewer pixel columns, or may be configured to include four or more pixel columns.

[0356] Fig. 17 is a view for explaining another example in which the display device according to the embodiment of the present specification operates in the first mode.

[0357] Fig. 17 illustrates an embodiment in which the display device 100, in the first mode, controls the brightness of the second lens area LSA2 of the first pixel PX1 arranged in the first area A1 on a line-by-line basis.

[0358] Meanwhile, Fig. 17 shows an example of the display panel PN in the case where the display device 100 according to the embodiment of the present description operates in the first mode.

[0359] With reference to Fig. 17, in the first mode, the display device 100 may control the brightness of the display panel PN such that the brightness of the first area A1 increases with increasing distance from the boundary between the first area A1 and the second area A2.

[0360] In the first mode, the display device 100 may control such that the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 increases line by line with increasing distance from the boundary between the first area A1 and the second area A2.

[0361] For example, in the first mode, the display device 100 may control such that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in the odd-numbered row, e.g., a first row R1 of the plurality of first pixels PX1 arranged in the odd-numbered columns, e.g., the first column C1 and the third column C3, increases with increasing distance from the boundary between the first area A1 and the second area A2.

[0362] In addition, in the first mode, the display device 100 may control such that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in the even-numbered row, e.g., a second row R2 of the plurality of first pixels PX1 arranged in the even-numbered columns, e.g., the second column C2 and the fourth column C4, increases with increasing distance from the boundary between the first area A1 and the second area A2.

[0363] More precisely, as in Fig. 17, the second lens area LSA2 of the first pixel PX1 provided in the first area A1 and arranged in the odd-numbered row, e.g., the first row R1 of the plurality of first pixels PX1 arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2, may emit light having a first brightness L1 lower than the reference brightness L0.

[0364] Meanwhile, the second lens area LSA2 of the first pixel PX1 arranged in the even-numbered row, e.g., in the second row R2 of the plurality of first pixels PX1 arranged in the first column C1, can emit light having the reference brightness L0.

[0365] In addition, the second lens area LSA2 of the first pixel PX1 provided in the first area A1 and arranged in the even-numbered row, e.g., the second row R2 of the plurality of first pixels PX1 arranged in the second column C2 adjacent to the first column C1 in the first direction DR1, may emit light having the second brightness L2 higher than the first brightness L1. In this case, the second brightness L2 may be lower than the reference brightness L0.

[0366] Meanwhile, the second lens area LSA2 of the first pixel PX1 arranged in the odd-numbered row, e.g., the first row R1 of the plurality of first pixels PX1 arranged in the second column C2, can emit light having the reference brightness L0.

[0367] Similarly, the second lens area LSA2 of the first pixel PX1 provided in the first area A1 and arranged in the odd-numbered row, e.g., the first row R1 of the plurality of first pixels PX1 arranged in the third column C3 adjacent to the second column C2 in the first direction DR1, may emit light having a third brightness L3 higher than the second brightness L2. In this case, the third brightness L3 may be lower than the reference brightness L0.

[0368] Meanwhile, the second lens area LSA2 of the first pixel PX1 arranged in the even-numbered row, e.g., in the second row R2 of the plurality of first pixels PX1 arranged in the third column C3, can emit light having the reference brightness L0.

[0369] Similarly, the second lens area LSA2 of the first pixel PX1 provided in the first area A1 and arranged in the even-numbered row, e.g., the second row R2 of the plurality of first pixels PX1 arranged in the fourth column C4 adjacent to the third column C3 in the first direction DR1, emits light having the fourth brightness L4 higher than the third brightness L3. In this case, the fourth brightness L4 may be lower than the reference brightness L0.

[0370] Meanwhile, the second lens area LSA2 of the first pixel PX1 arranged in the odd-numbered row, e.g., the first row R1 of the plurality of first pixels PX1 arranged in the fourth column C4, can emit light having the reference brightness L0.

[0371] Similarly, the second lens area LSA2 of the first pixel PX1 provided in the first region A1 and arranged in the even-numbered row, e.g., the second row R2 of the plurality of first pixels PX1 arranged in the (m-1)th column Cm-1 adjacent to the mth column Cm farthest from the boundary between the first region A1 and the second region A2 in the direction opposite to the first direction DR1, may emit light having the fifth brightness L5 higher than the fourth brightness L4. In this case, the fifth brightness L5 may be lower than the reference brightness L0.

[0372] Meanwhile, the second lens area LSA2 of the first pixel PX1 arranged in the odd-numbered row, e.g., the first row R1 of the plurality of first pixels PX1 arranged in the (m-1)th column Cm-1, can emit light having the reference brightness L0.

[0373] In addition, the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and located in the m-th column Cm farthest from the boundary between the first area A1 and the second area A2 may emit light at the reference brightness L0. For example, the display device 100 may control such that the brightness of the first lens area LSA1 and the second lens area LSA2 of each of the plurality of first pixels PX1 located in the pixel column (the m-th column Cm) farthest from the boundary between the first area A1 and the second area A2, among the plurality of first pixels PX1 located in the first area A1, corresponds to the input image data IDATA.

[0374] As described above, in the first mode, the display device 100 can control such that the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first area A1 increases in the first direction DR1, that is, increases on a row-by-row basis as the distance from the boundary between the first area A1 and the second area A2 increases. For example, the display device 100 can control such that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in the odd-numbered row, e.g., the first row R1 of the plurality of first pixels PX1 arranged in the odd-numbered columns, e.g., in the first column C1 and the third column C3, increases from the first column C1 to the m-th column Cm, and the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in the even-numbered row, e.g.,the second row R2 of the plurality of first pixels PX1 arranged in the even-numbered columns, e.g., in the second column C2 and the fourth column C4, increases from the first column C1 to the mth column Cm. For example, in the first mode, the display device 100 may control such that the brightness of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in a zigzag shape in the first region A1 increases in the first direction DR1 from the boundary between the first region A1 and the second region A2.

[0375] Therefore, it is possible to minimize or mitigate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized when images are displayed in the first mode.

[0376] Substantially identical or similar to that relating to Fig. 12, the first brightness L1 of the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the odd-numbered row in the first column C1 closest to the boundary between the first area A1 and the second area A2 may be the brightness substantially corresponding to a black image, for example, a value of 0. Therefore, it is possible to more effectively solve or mitigate the problem that the boundary between the first area A1 and the second area A2 is visually recognized when images are displayed in the first mode. However, the embodiment of the present description is not limited to this.The second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the odd-numbered row in the first column C1 closest to the boundary between the first area A1 and the second area A2 may not emit light.

[0377] In addition, the display device 100 may be substantially identical or similar to that described with reference to Fig. 12, in the first mode, the control so that the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the first area A1 increases linearly in the first direction DR1, that is, increases with increasing distance from the boundary between the first area A1 and the second area A2. Therefore, it is possible to minimize or mitigate a problem in which the change in the brightness of the first area A1, e.g., the change in the brightness in the first direction DR1, is visually recognized by the user.

[0378] Meanwhile, the configuration in Fig. 17, in which the display device 100, in the first mode, performs control such that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in the odd-numbered row among the plurality of first pixels PX1 arranged in the odd-numbered column and the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in the even-numbered row among the plurality of first pixels PX1 arranged in the even-numbered column increases with increasing distance from the boundary between the first area A1 and the second area A2. However, the present disclosure is not limited thereto.For example, in the first mode, the display device 100 may control such that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in the even-numbered row among the plurality of first pixels PX1 arranged in the odd-numbered column and the brightness of the second lens area LSA2 of the plurality of first pixels PX1 arranged in the odd-numbered row among the plurality of first pixels PX1 arranged in the even-numbered column increases with increasing distance from the boundary between the first area A1 and the second area A2.

[0379] Fig. 18 is a view for explaining another example in which the display device according to the embodiment of the present specification operates in the first mode.

[0380] Fig. 18 is an embodiment in which the display device 100 alternately controls, on a line-by-pixel basis, the brightness of the second lens area LSA2 of the first pixel PX1 arranged in a partial area of the first area A1, e.g., the third area A3, in the first mode.

[0381] Meanwhile, Fig. 18 shows an example of the display panel PN in the case where the display device 100 according to the embodiment of the present description operates in the first mode.

[0382] With reference to Fig. 18, in the first mode, the display device 100 can control the brightness of the first area A1 of the display panel PN such that the brightness of a partial area, e.g., the third area A3 of the first area A1, increases with increasing distance from the boundary between the first area A1 and the second area A2.

[0383] In the first mode, the display device 100, e.g., the brightness control means LD, may control such that the brightness of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the third region A3 increases row by pixel as the distance from the boundary between the first region A1 and the second region A2 increases.

[0384] For example, in the first mode, the display device 100, e.g., the brightness control means LD, may control such that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 provided in the third area A3 and arranged in the odd-numbered row, e.g., in a first row R1 of the plurality of first pixels PX1 arranged in the odd-numbered columns, e.g., in the first column C1 and in the third column C3, increases with increasing distance from the boundary between the first area A1 and the second area A2.

[0385] In addition, in the first mode, the display device 100 may control such that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 provided in the third area A3 and arranged in the even-numbered row, e.g., in the second row R2, of the plurality of first pixels PX1 arranged in the even-numbered column, e.g., in the second column C2, increases with increasing distance from the boundary between the first area A1 and the second area A2.

[0386] More precisely, as in Fig. 18, the second lens area LSA2 of the first pixel PX1 provided in the first area A1 and arranged in the odd-numbered row, e.g., in the first row R1 of the plurality of first pixels PX1 arranged in the first column C1 closest to the boundary between the first area A1 and the second area A2, can emit light having a sixth brightness L6 lower than the reference brightness L0.

[0387] Meanwhile, the second lens area LSA2 of the first pixel PX1 arranged in the even-numbered row, e.g., the second row R2 of the plurality of first pixels PX1 arranged in the first column C1, can emit light having the reference brightness L0.

[0388] In addition, the second lens area LSA2 of the first pixel PX1 provided in the first area A1 and arranged in the even-numbered row, e.g., in the second row R2 of the plurality of first pixels PX1 arranged in the second column C2 adjacent to the first column C1 in the first direction DR1, may emit light having the seventh brightness L7 higher than the sixth brightness L6. In this case, the seventh brightness L7 may be lower than the reference brightness L0.

[0389] Meanwhile, the second lens area LSA2 of the first pixel PX1 arranged in the odd-numbered row, e.g., in the first row R1 of the plurality of first pixels PX1 arranged in the second column C2, can emit light having the reference brightness L0.

[0390] Similarly, the second lens area LSA2 of the first pixel PX1 provided in the first area A1 and arranged in the odd-numbered row, e.g., in the first row R1 of the plurality of first pixels PX1 arranged in the third column C3 adjacent to the second column C2 in the first direction DR1, may emit light having the eighth brightness L8 higher than the seventh brightness L7. In this case, the eighth brightness L8 may be lower than the reference brightness L0.

[0391] In addition, the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the remaining area of the first area A1 excluding the third area A3 may emit light at the reference brightness L0. For example, the display device 100 may control the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the remaining area excluding the third area A3, e.g., in the fourth area A4, of the plurality of first pixels PX1 arranged in the first area A1, to correspond to the input image data IDATA.

[0392] As described above, in the first mode, the display device 100 can control the brightness of the second lens area LSA2 of each of the plurality of first pixels PX1 arranged in the third area A3 to increase in the first direction DR1, that is, to increase on a pixel-by-pixel basis, as the distance from the boundary between the first area A1 and the second area A2 increases. Therefore, it is possible to minimize or mitigate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized when displaying images in the first mode.

[0393] Substantially identical or similar to that relating to Fig. 12, the sixth brightness L6 of the second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the odd-numbered row, e.g., in the first row R1 in the first column C1 closest to the boundary between the first area A1 and the second area A2, may have a brightness substantially corresponding to a black image, e.g., a value of 0. Therefore, it is possible to more effectively solve or mitigate the problem in which the boundary between the first area A1 and the second area A2 is visually recognized when images are displayed in the first mode. However, the embodiment of the present description is not limited to this. The second lens area LSA2 of each of the plurality of first pixels PX1 provided in the first area A1 and arranged in the odd-numbered row, e.g.,the first row R1 in the first column C1 closest to the boundary between the first region A1 and the second region A2 may not emit light.

[0394] In addition, the display device 100 may be substantially identical or similar to that described with reference to Fig. 12, 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 the first area A1 increases linearly in the first direction DR1, that is, increases with increasing distance from the boundary between the first area A1 and the second area A2. Therefore, it is possible to minimize or mitigate a problem in which the change in the brightness of the first area A1, e.g., the change in the brightness in the first direction DR1, is visually recognized by the user.

[0395] Meanwhile, the configuration in Fig. 18, in the first mode, the display device 100 performs control such that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 provided in the third area A3 and arranged in the odd-numbered row among the plurality of first pixels PX1 arranged in the odd-numbered column increases, and the brightness of the second lens area LSA2 of the plurality of first pixels PX1 provided in the third area A3 and arranged in the even-numbered row among the plurality of first pixels PX1 arranged in the even-numbered column increases as the distance from the boundary between the first area A1 and the second area A2 increases. However, the present disclosure is not limited to this.For example, in the first mode, the display device 100 may control such that the brightness of the second lens area LSA2 of the plurality of first pixels PX1 provided in the third area A3 and arranged in the even-numbered row among the plurality of first pixels PX1 arranged in the odd-numbered column, and the brightness of the second lens area LSA2 of the plurality of first pixels PX1 provided in the third area A3 and arranged in the odd-numbered row among the plurality of first pixels PX1 arranged in the even-numbered column increases with increasing distance from the boundary between the first area A1 and the second area A2.

[0396] Meanwhile, the configuration in Fig.18, in which the third region A3 of the first region A1 adjacent to the second region A2 includes the first to third columns C1, C2, and C3, for example, the three pixel columns. However, this configuration is for illustrative purposes only, and the embodiment of the present description is not limited thereto. For example, the third region A3 may be configured to include two or fewer pixel columns, or may be configured to include four or more pixel columns.
