Description

Technical Field

[0001] This specification relates to a display device, and more particularly, to a display device capable of controlling a viewing angle.

Background Art

[0002] As technology in modern society develops, display devices are widely used to provide information to users. A display device may be simply included in an electro-optical panel that transmits visual information in one direction, or may also be included in various electronic devices that require higher technology to check user input and provide information corresponding to the confirmed input.

[0003] For example, a display device can be included in a vehicle to provide various information to the driver and passengers of the vehicle. However, the display device in the vehicle needs to appropriately display content so as not to interfere with the operation of the vehicle. For example, the display device needs to limit the display of content that can reduce the driver's concentration during vehicle operation.

Summary of the Invention

Problems to be Solved by the Invention

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

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

Means for Solving the Problems

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

[0007] Specific matters of other embodiments are included in the detailed description and the drawings.

[0008] This specification can control the luminance of the display panel such that in a first mode of providing content at a wide viewing angle according to a driving mode, the luminance of the first region increases as the distance from the boundary between the first region and the second region increases.

[0009] This specification can control the luminance of the region adjacent to the boundary between the first region and the second region in the first region to have a value substantially the same as or similar to the luminance of the second region, so that the problem of the boundary between the first region and the second region being visible can be improved.

[0010] The effects according to the present invention are not limited to the contents illustrated above, and the present invention includes more various effects.

However, the present specification is not limited to the embodiments disclosed below, and is embodied in various different forms. Merely, these embodiments are provided so that the disclosure of the present specification becomes complete and that those having ordinary knowledge in the technical field to which the present specification pertains are fully informed of the scope of the specification.

[0013] The shapes, areas, ratios, angles, numbers, etc. disclosed in the drawings for explaining the embodiments of the present specification are exemplary, and thus the present specification is not limited to the matters illustrated. Throughout the specification, the same reference numerals refer to the same components. Also, when explaining the present specification, if it is determined that a detailed description of related known technologies may obscure the gist of the present specification, the detailed description thereof is omitted. When terms such as "including," "having," and "being made" are used in the present specification, unless "only" is used, other parts can be added. When a component is expressed in the singular, it includes the case of including a plurality unless otherwise explicitly stated.

[0014] When interpreting a component, it is interpreted as including an error range even without a separate explicit description.

[0015] When it comes to the description of the positional relationship, for example, when the positional relationship between two parts is described such as "above ~", "on the upper part of ~", "on the lower part of ~", "next to ~", etc., as long as "immediately" or "directly" is not used, one or more other parts may be located between the two parts.

[0016] What is referred to as "on" an element or layer of another element or layer includes both cases where there is another layer or another element immediately above or with another layer or another element intervening in the middle of the other element.

[0017] Also, although the first, second, etc. are used to describe various components, these components are not limited by these terms. These terms are merely used to distinguish one component from another. Therefore, the first component mentioned below may be the second component within the technical idea of this specification.

[0018] Throughout the specification, the same reference signs refer to the same components.

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

[0020] The respective features of the various embodiments of this specification can be partially or wholly combined or combined with each other, enabling various interlocks and operations technically, and each embodiment may be implemented independently of each other or may be implemented in cooperation with each other.

[0021] Hereinafter, this specification will be described with reference to the drawings.

[0022] FIG. 1 is an exemplary view of a display device according to an embodiment of this specification.

[0023] Referring to FIG. 1, the display device 100 can be disposed on at least a part of the dashboard of the vehicle. The dashboard of the vehicle can include a configuration disposed in front of the front seats (e.g., driver's seat, passenger seat) of the vehicle. For example, the dashboard of the vehicle can have input configurations for operating various functions inside the vehicle (e.g., air conditioner, audio system, navigation system).

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

[0025] The display device 100 can be disposed so as to cross the driver's seat and the passenger seat disposed in front of the vehicle. The users of the display device 100 can include the driver of the vehicle and the passengers boarding the passenger seat. Any of the driver and the passengers of the vehicle can use the display device 100.

[0026] The display device 100 shown in FIG. 1 may show only a part. The display device 100 shown in FIG. 1 may show a display panel among various configurations included in the display device 100. Specifically, by way of example, the display device 100 shown in FIG. 1 may show at least a part of the display area and the non-display area of the display panel. Configurations of the display device 100 other than the part shown in FIG. 1 can be implemented inside the vehicle (or at least a part thereof).

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

[0028] The display device according to an embodiment of the present specification may apply an electroluminescent display device. As the electroluminescent display device, an organic light emitting diode (OLED) display device, a quantum-dot light emitting diode (QLED) display device, or an inorganic light emitting diode (ILED) display device may be used.

[0029] Referring to FIG. 2, the display device 100 may include a display panel PN, a data driving circuit DD, a gate driving circuit GD, a timing controller TD, and a luminance controller LD. The display device 100 may further include a mode controller MS and a mode selector MD.

[0030] The display panel PN can generate an image provided to the user. For example, the display panel PN can generate and display an image provided to the user through a plurality of pixels PX in which pixel circuits are respectively arranged.

[0031] The plurality of pixels PX may include a first pixel and a second pixel arranged by region of the display panel PN. Details of the first pixel, the second pixel, and the arrangement relationship therewith will be described later with reference to FIGS. 8A to 11.

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

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

[0034] A plurality of data wirings DL are arranged in the column direction and can include a plurality of wirings connected to pixels PX arranged in one column direction. A plurality of gate wirings GL are arranged in the row direction and can include a plurality of wirings connected to pixels PX arranged in one row direction.

[0035] Also, a plurality of selection signal wirings SSL are arranged in the row direction and can include a plurality of wirings connected to pixels PX arranged in one row direction.

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

[0037] In some cases, the display device 100 can further include a power supply unit. In such a case, signals for the operation of the pixel PX can be provided through a power wiring connecting the power supply unit and the display panel PN. According to an embodiment, the power supply unit can supply power to the data driving circuit DD and the gate driving circuit GD. The data driving circuit DD and the gate driving circuit GD can be driven based on the power supplied from the power supply unit.

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

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

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

[0041] For example, when the display device 100 is in the first mode in which the entire area of the display panel PN is controlled in the wide viewing angle mode (Share mode), the luminance controller LD can generate corrected video data CDATA for controlling the luminance of at least a part of the display panel PN, for example, the first area. As an example, in the first mode, the luminance controller LD can generate corrected video data CDATA for reducing the luminance of the first area.

[0042] The luminance controller LD can generate the corrected video data CDATA by scaling the gradation values included in the input video data IDATA using a scale factor. For example, the luminance controller LD can generate the corrected video data CDATA by performing scaling on the gradation values corresponding to at least a part of the display panel PN, for example, the first area. However, this is merely exemplary, and the method by which the luminance controller LD generates the corrected video data CDATA is not limited thereto.

[0043] As another example, in a second mode in which at least a partial region of the display panel PN, for example, a first region, is controlled to be in a wide viewing angle mode (Share mode) and another partial region, for example, a second region, is controlled to be in a narrow viewing angle mode (Private mode), the luminance controller LD can generate correction video data CDATA for controlling the luminance of the entire region of the display panel PN to correspond to the input video data IDATA.

[0044] In such a second mode, since the luminance of the entire region of the display panel PN must correspond to the input video data IDATA, the correction video data CDATA can be substantially the same as the input video data IDATA. For example, in the second mode, the luminance controller LD can perform no correction on the input video data IDATA and output the input video data IDATA as the correction video data CDATA as it is.

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

[0046] Here, as described above, when the display device 100 is driven in the first mode, based on the correction video data CDATA generated by scaling the gradation value of the input video data IDATA by the luminance controller LD, the luminance of the video displayed on at least a partial region of the display panel PN, for example, the first region, can be controlled. A detailed description of the configuration in which the luminance of the display panel PN is controlled based on the correction video data CDATA will be described later with reference to FIGS. 12 to 18.

[0047] On the one hand, in FIG. 2, for the sake of convenience of explanation, the description was based on the premise that the luminance controller LD and the timing controller TD have separate configurations, but it is not limited thereto. For example, part or all of the luminance controller LD may be integrated into the timing controller TD for configuration.

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

[0049] The gate driving circuit GD can generate a scan signal and a light emission signal (or a light emission control signal) based on the gate control signal. For example, the gate driving circuit GD can include a scan driving unit and a light emission signal driving unit. The scan driving unit can generate a scan signal in a row sequential manner to drive at least one or more scan wirings connected for each row of pixels and supply it to the scan wiring. The light emission signal driving unit can generate a light emission signal in a row sequential manner to drive at least one or more light emission signal wirings connected for each row of pixels and supply it to the light emission signal wiring.

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

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

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

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

[0054] One pixel PX can include a plurality of sub-pixels that emit different colors. For example, one pixel PX can implement blue, red, and green using three sub-pixels. However, it is not limited thereto, and in some cases, the pixel PX can further include a sub-pixel for further implementing a specific color, for example, white.

[0055] The area for implementing blue in the pixel PX can be referred to as a blue sub-pixel, the area for implementing red can be referred to as a red sub-pixel, and the area for implementing green can be referred to as a green sub-pixel.

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

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

[0058] For example, the first type of lens is arranged in a lens area that provides light to a first range to form a first viewing angle, and the second type of lens can be arranged in a lens area that provides light to a second range to form a second viewing angle. The first range can correspond to a wider range than the second range. Therefore, the first type of lens and the second type of lens can limit the viewing angle of each of the plurality of pixels PX.

[0059] Detailed descriptions of the first type of lens and the second type of lens will be described later with reference to FIGS. 6 and 7.

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

[0061] The display panel PN can be divided into a plurality of areas. In other words, the display panel PN can include a plurality of areas. For example, the display panel PN can include a first area where a plurality of first pixels among the plurality of pixels PX are arranged and a second area where a plurality of second pixels among the plurality of pixels PX are arranged. Each of the plurality of first pixels arranged in the first area and the plurality of second pixels arranged in the second area can include the same pixel circuit.

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

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

[0064] Also, the selection circuit may be a circuit for controlling to generate at least one of a first driving current passing through the first type of light-emitting element and a second driving current passing through the second type of light-emitting element based on a selection signal provided from the mode selection unit MD. In other words, by the control of the selection circuit, a current path of the first driving current can be formed so that the first type of light-emitting element emits light, or a current path of the second driving current can be formed so that the second type of light-emitting element emits light. However, it is not limited to this, and the selection circuit can also be defined as being included in the driving circuit.

[0065] On the other hand, for the sake of convenience of explanation, hereinafter, when the current path of the first drive current is formed and the first type of light-emitting element emits light, it is defined that the pixel PX is driven in the first state, and when the current path of the second drive current is formed and the second type of light-emitting element emits light, it is defined that the pixel PX is driven in the second state.

[0066] The selection circuit can be controlled based on the selection signal provided from the mode selection unit MD so that both the first drive current passing through the first type of light-emitting element and the second drive current passing through the second type of light-emitting element are formed. In other words, by controlling such a selection circuit, the current path of the first drive current and the current path of the second drive current are respectively formed, and all the first type of light-emitting element and the second type of light-emitting element can emit light.

[0067] On the other hand, for the sake of convenience of explanation, hereinafter, when the current paths of the first drive current and the second drive current are respectively formed and all the first type of light-emitting element and the second type of light-emitting element emit light, it is defined that the pixel PX is driven in the third state.

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

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

[0070] Detailed descriptions of the plurality of regions included in the display panel PN, for example, the first region and the second region, and the first and second pixels disposed in the first region and the second region will be described later with reference to FIGS. 8A to 11.

[0071] According to an embodiment, each region of the display panel PN is disposed so as to cross the driver's seat and the passenger seat disposed in the front seats of the vehicle described with reference to FIG. 1, and can provide various information to the driver and passengers of the vehicle. For example, the first region of the display panel PN is a region provided on the driver's seat side disposed in the front seats of the vehicle, and provides information such as the traveling speed, RPM, engine temperature, fuel amount, etc., and the second region of the display panel PN is a region provided on the passenger seat side disposed in the front seats of the vehicle, and can provide an entertainment function and seat information for the passenger sitting in the passenger seat. On the other hand, the first region of the display panel PN can further include a center fascia region disposed between the driver's seat and the passenger seat. However, such a region division is for convenience of explanation, and the first region and the second region in the display panel PN can be defined variously according to the design.

[0072] On the one hand, when the display panel PN is used in the vehicle described with reference to FIG. 1, it is necessary to limit the viewing field of at least some of the plurality of regions included in the display panel PN according to the user's request. For example, in the case of the video displayed in the second region that provides entertainment functions and seat information for the passenger sitting in the passenger seat, since it may interfere with the driver's vehicle operation, it may be necessary to limit the viewing field of the video displayed in the second region according to the user's request.

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

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

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

[0076] Also, when the display device 100 is driven in the first mode, under the control of the mode controller MS, the second region of the display panel PN can be driven in the first state. In this case, the first type of light-emitting elements included in each of the plurality of second pixels disposed on the second region of the display panel PN can emit light, and the second type of light-emitting elements can be non-emitting. As a result, the light generated from the first type of light-emitting elements included in each of the plurality of second pixels can be emitted at the first viewing angle through the third lens. Therefore, when the display device 100 is driven in the first mode, content in the wide viewing angle mode can be provided from the plurality of second pixels disposed on the second region of the display panel PN.

[0077] Also, when the display device 100 is driven in the second mode, under the control of the mode controller MS, the second region of the display panel PN can be driven in the second state. In this case, the second type of light-emitting elements included in each of the plurality of second pixels disposed on the second region of the display panel PN can emit light, and the first type of light-emitting elements can be non-emitting. As a result, the light generated from the second type of light-emitting elements 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 is driven in the second mode, content in the narrow viewing angle mode can be provided from the plurality of second pixels disposed on the second region of the display panel PN.

[0078] A detailed description of the configuration in which the mode controller MS controls the display panel PN in the first mode or the second mode according to the driving mode of the display device 100 will be described later with reference to FIGS. 12 and 13.

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

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

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

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

[0083] The driving transistor DT and the first capacitor C1 can be connected to the switching transistor ST. The first electrode of the driving transistor DT can be connected to a first power supply wiring that provides a first power supply voltage VDD, for example, a high potential power supply voltage.

[0084] The switching transistor ST is connected to a gate wiring GL and can receive a supply of a 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 a data wiring DL. In such a case, a data signal can be supplied to the gate electrode of the driving transistor DT through the switching transistor ST in response to the switching transistor ST being turned on.

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

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

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

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

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

[0090] In such a case, the first type of light-emitting element EDa or the second type of light-emitting element EDb can be connected to other components of the pixel circuit SPC, for example, the drive transistor DT of the drive circuit DC, depending on the drive mode. Here, the drive mode can be determined when specified by a user input or when a pre-specified condition is satisfied.

[0091] For example, the drive mode can include a first mode in which a plurality of regions of the display panel PN described with reference to FIG. 2 are all controlled in a wide viewing angle mode (Share mode), and a second mode in which at least some regions of the plurality of regions of the display panel PN, for example, a second region, are driven in a narrow viewing angle mode (Private mode).

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

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

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

[0095] On the other hand, FIG. 4 can show an exemplary pixel circuit SPC_1 applicable to the pixel circuit SPC shown in FIG. 3.

[0096] Referring to FIG. 4, at least some of the plurality of transistors included in the pixel circuit SPC_1 may be n-type transistors or p-type transistors. In the case of p-type transistors, the low level voltage of each drive signal may mean the voltage to turn on the TFT, and the high level voltage of each drive signal may mean the voltage to turn off the TFT.

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

[0098] Hereinafter, the first electrode or the second electrode of the transistor to be described later may mean the source electrode or the drain electrode. However, the terms "first electrode" and "second electrode" are only terms for distinguishing each electrode and do not limit what each electrode corresponds to. Also, the first electrode may not refer to the same electrode for each electrode.

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

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

[0101] The driving transistor DT can control the driving current applied to the plurality of light emitting elements EDa and EDb by the source-gate voltage. The driving transistor DT can include a source electrode connected to a first power supply wiring that provides a first power supply voltage VDD, for example, a high potential power supply voltage, a gate electrode connected to a second node N2, and a drain electrode connected to a third node N3.

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

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

[0104] The third switching transistor ST3 can apply a reference voltage Vref to the first node N1. The third switching transistor ST3 can include a source electrode connected to a reference voltage wiring that provides the reference voltage Vref, a drain electrode connected to the first node N1, and a gate electrode connected to a light emission signal wiring EL to which a light emission signal EM is applied. The third switching transistor ST3 can be turned on or off by the light emission signal EM. Therefore, the third switching transistor ST3 can transmit the reference voltage Vref to the first node N1 in response to the light emission signal EM at a turn-on level, which is a low level.

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

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

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

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

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

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

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

[0112] In such a case, the first type of light-emitting element EDa or the second type of light-emitting element EDb can be connected to other components of the pixel circuit SPC_1, for example, the drive transistor DT of the drive circuit DC_1, depending on the drive mode. Here, the drive mode can be determined when specified by a user input or when satisfying a pre-specified condition.

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

[0114] FIGS. 5A and 5B are waveform diagrams for explaining the pixel circuit of FIG. 4.

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

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

[0117] Specifically, first, referring to FIGS. 4 and 5a, when the pixel circuit SPC_1 operates in the first state, a low-level second scan signal SCAN2, a low-level first selection signal Ss, and a low-level emission signal EM can be output during the initialization period. The second switching transistor ST2, the fourth switching transistor ST4, and the fifth switching transistor ST5 are turned on by the low-level second scan signal SCAN2, the first selection transistor TP1 is turned on by the low-level first selection signal Ss, and the third switching transistor ST3 can be turned on by the low-level emission signal EM.

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

[0119] Next, a low-level first scan signal SCAN1 and a low-level second scan signal SCAN2 are output during the sampling period, and the first selection signal Ss can be output at a high level. When a high-level emission signal EM is output and the third switching transistor ST3 is turned off, the first switching transistor ST1 is turned on by the low-level first scan signal SCAN1, and a data signal can be transmitted to the first node N1. Then, the driving transistor DT is diode-connected by the turned-on second switching transistor ST2, and a differential voltage between the first power supply voltage VDD and the threshold voltage can be sampled and supplied to the second node N2.

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

[0121] Finally, a low-level first selection signal Ss and an emission signal EM are output during the emission period, and a high-level second selection signal Ps can be output. A reference voltage Vref is applied to the first node N1 through the third switching transistor ST3 turned on by the low-level emission signal EM, and the voltage of the first node N1 can become a differential voltage between the reference voltage Vref and the data signal (data voltage), and such a voltage fluctuation can also be reflected in the second node N2. The gate-source voltage of the driving transistor DT is set to a value (Vdata - Vref + Vth) obtained by subtracting the reference voltage Vref from the data signal (data voltage) and adding the data signal (data voltage), and the first drive current can be controlled.

[0122] Then, a first driving current is supplied from the driving transistor DT to the first type of light-emitting element EDa through the turned-on first selection transistor TP1, and the first type of light-emitting element EDa can emit light. However, since the second selection signal Ps is output at a high level and the second selection transistor TP2 is turned off, the second driving current cannot be transmitted from the driving transistor DT to the second type of light-emitting element EDb. Therefore, when the pixel circuit SPC_1 is driven in the first state, only the first driving current is applied to the first type of light-emitting element EDa, and only the first type of light-emitting element EDa can emit light.

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

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

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

[0126] Next, a low-level first scan signal SCAN1 and a low-level second scan signal SCAN2 are output during the sampling period, and the second selection signal Ps and the emission signal EM can be output from the low level to the high level. When the high-level emission signal EM is output, the third switching transistor ST3 is turned off, and the first switching transistor ST1 is turned on by the low-level first scan signal SCAN1, and the data signal can be transmitted to the first node N1. Then, the driving transistor DT is diode-connected by the turned-on second switching transistor ST2, and the differential voltage between the first power supply voltage VDD and the threshold voltage can be sampled and supplied to the second node N2.

[0127] Finally, a low-level second selection signal Ps and a light emission signal EM may be output during the light emission period, and a high-level first selection signal Ss may be output. A reference voltage Vref is applied to the first node N1 through a third switching transistor ST3 turned on by the low-level light emission signal EM, and the voltage of the first node N1 may become a differential voltage between the reference voltage Vref and the data signal (data voltage), and such voltage fluctuations may also be reflected in the second node N2. The gate-source voltage of the driving transistor DT is set to a value (Vdata - Vref + Vth) obtained by subtracting the reference voltage Vref from the data signal (data voltage) and adding the data signal (data voltage), and the second driving current may be controlled.

[0128] Then, a second driving current is supplied from the driving transistor DT to the second type of light emitting element EDb through the turned-on second selection transistor TP2, and the second type of light emitting element EDb can emit light. However, since the first selection signal Ss is output at a high level and the first selection transistor TP1 is turned off, the first driving current cannot be transmitted from the driving transistor DT to the first type of light emitting element EDa. Therefore, when the pixel circuit SPC_1 is driven in the second state, the second driving current is applied only to the second type of light emitting element EDb, and only the second type of light emitting element EDb can emit light.

[0129] On the other hand, although not shown in FIGS. 5A and 5B, when the pixel circuit SPC_1 is driven in the third state, both the first type of light emitting element EDa and the second type of light emitting element EDb emit light. Therefore, the waveform of the first selection signal Ss in the third state and the operation of the pixel circuit SPC_1 in which the first driving current is formed thereby, and the waveform of the first selection signal Ss in the first state and the operation of the pixel circuit SPC_1 in which the first driving current is formed thereby described with reference to FIG. 5A are substantially the same or similar. Also, the waveform of the second selection signal Ps in the third state and the operation of the pixel circuit SPC_1 in which the second driving current is formed thereby, and the waveform of the second selection signal Ps in the second state and the operation of the pixel circuit SPC_1 in which the second driving current is formed thereby described with reference to FIG. 5B are substantially the same or similar. Thus, redundant descriptions will not be repeated.

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

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

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

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

[0134] A buffer film 111 may be arranged 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 laminated structure of a film made of silicon nitride (SiNx) and a film made of silicon oxide (SiOx).

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

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

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

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

[0139] On the interlayer insulating film 113, a lower protective film 114 can be disposed. The lower protective film 114 can contain an insulating material. For example, the lower protective film 114 can contain an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN). The lower protective film 114 can prevent damage to the driving portion due to external moisture and impact. The lower protective film 114 can extend along the surfaces of the driving transistor DT and the switching transistor ST facing the substrate 110. The lower protective film 114 can be in contact with the interlayer insulating film 113 outside the driving portion located within each pixel PX.

[0140] On the lower protective film 114, an overcoat layer 115 can be disposed. The overcoat layer 115 can contain an insulating material. The overcoat layer 115 can contain a material different from that of the lower protective film 114. For example, the overcoat layer 115 can contain an organic insulating material. The overcoat layer 115 can remove the step caused by the driving portion of each pixel PX. For example, the upper surface of the overcoat layer 115 facing the element substrate 110 can be a flat surface.

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

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

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

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

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

[0146] The first bottom electrode 141 can contain a conductive material. The first bottom electrode 141 can contain a material with a high reflectivity. For example, the first bottom electrode 141 can contain metals such as aluminum (Al) and silver (Ag). The first bottom electrode 141 can have a multilayer structure. For example, the first bottom electrode 141 can have a structure in which a reflective electrode made of metal is positioned between transparent electrodes made of transparent conductive materials such as ITO and IZO. The first bottom electrode 141 can be electrically connected to the first drain electrode 124 of the first selection transistor TP1 through a contact hole that penetrates the bottom protective film 114 and the overcoat layer 115.

[0147] The first light-emitting layer 142 can generate light with a luminance corresponding to the voltage difference between the first bottom electrode 141 and the first top electrode 143. For example, the first light-emitting layer 142 can contain a light-emitting material layer (Emission Material Layer; EML) containing a light-emitting material. The light-emitting material can contain an organic material, an inorganic material, or a hybrid material.

[0148] The first light-emitting layer 142 can have a multilayer structure. For example, the first light-emitting layer 142 can further contain at least one of a hole injection layer (Hole Injection Layer; HIL), a hole transport layer (Hole Transport Layer; HTL), an electron transport layer (Electron Transport Layer; ETL), and an electron injection layer (Electron Injection Layer; EIL).

[0149] The first top electrode 143 can contain a conductive material. The first top electrode 143 can contain a material different from that of the first bottom electrode 141. The transmittance of the first top electrode 143 can be higher than that of the first bottom electrode 141. For example, the first top electrode 143 can be a transparent electrode made of a transparent conductive material such as ITO and IZO. Accordingly, in the display device 100 according to the embodiments of this specification, the light generated by the first light-emitting layer 142 can be emitted through the first top electrode 143.

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

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

[0152] The second light-emitting layer 152 may be separated from the first light-emitting layer 142. Thereby, in the display device according to the embodiments of the present specification, light emission due to leakage current can be prevented.

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

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

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

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

[0157] A sealing member 180 can be located on the first type of light-emitting element EDa and the second type of light-emitting element EDb of each pixel PX. The sealing member 180 can prevent damage to the light-emitting elements EDa and EDb due to moisture and impact from the outside. The sealing member 180 can have a multilayer structure. For example, the sealing member 180 can include a first sealing layer 181, a second sealing layer 182, and a third sealing layer 183 laminated in sequence, but is not limited thereto. The first sealing layer 181, the second sealing layer 182, and the third sealing layer 183 can include an insulating material. The second sealing layer 182 can include a different material from the first sealing layer 181 and the third sealing layer 183. For example, the first sealing layer 181 and the third sealing layer 183 are inorganic sealing layers including an inorganic insulating material, and the second sealing layer 182 can include an organic sealing layer including an organic insulating material. Thereby, damage to the light-emitting element ED of the display device 100 due to moisture and impact from the outside can be more effectively prevented.

[0158] The first type of lens 161 and the second type of lens 162 can be arranged on the sealing member 180.

[0159] The first type of lens 161 can be disposed on the first type of light-emitting element EDa. The light generated by the first type of light-emitting element EDa of each pixel PX can be emitted through the first type of lens 161 of the corresponding pixel PX. The first type of lens 161 can have a shape in which the light in at least one lateral direction does not need to be restricted. For example, the planar shape of the first type of lens 161 located within each pixel PX can have a bar shape extending in one direction.

[0160] In such a case, the traveling direction of the light emitted from the first type of lens region LSAa of each pixel PX does not need to be restricted in one direction. For example, the content (or image) provided through the first type of lens region LSAa of each pixel PX can be shared with the people around who are adjacent to the user in one direction. Thereby, the content provided by the light emitted through the first type of lens 161 can be provided in a first viewing angle range having a wider viewing angle than the content provided by the light emitted through the second type of lens 162. For example, the content provided by the light emitted through the first type of lens 161 can be provided in a wide viewing angle (Share mode).

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

[0162] In such a case, the traveling direction of the light emitted from the second type of lens region LSAb of each pixel PX can be restricted to one direction and / or another direction. For example, the content (or image) provided by the second type of lens region LSAb of each pixel PX does not need to be shared with the people around the user. Accordingly, the content provided by the light emitted through the second type of lens 162 can be provided within a second viewing angle range that has a narrower viewing angle than the content provided by the light emitted through the first type of lens 161. For example, the content provided by the light emitted through the second type of lens 162 can be provided in a private mode.

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

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

[0165] Referring to FIG. 6, when the pixel PX includes the first type of lens 161, the first type of lens region LSAa where the first type of lens 161 is disposed may include one light-emitting region, for example, one first type of light-emitting region EAa. Also, referring to FIG. 7, when the pixel PX includes the second type of lens 162, the second type of lens region LSAb where the second type of lens 162 is disposed may include a plurality of light-emitting regions, for example, a plurality of second type of light-emitting regions EAb.

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

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

[0168] A lens protection film 170 may be located on the first type of lens 161 and the second type of lens 162 of the pixel PX. The lens protection film 170 may include an insulating material. For example, the lens protection film 170 may include an organic insulating material. The refractive index of the lens protection film 170 may be smaller than the refractive indices of the first type of lens 161 and the second type of lens 162 located within each pixel PX. Accordingly, in the display device 100 according to the embodiments of the present specification, the light passing through the first type of lens 161 and the second type of lens 162 of each pixel PX does not need to be reflected in the direction of the substrate 110 due to the refractive index difference with the lens protection film 170.

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

[0170] For example, the pixel PX can also include a plurality of first-type lenses 161 disposed above the first-type light-emitting element EDa and above the second-type light-emitting element EDb, respectively. A detailed description thereof will be given later with reference to FIGS. 8a and 8b.

[0171] FIG. 8a is a circuit diagram showing an example of a first pixel of a display device according to an embodiment of the present specification. FIG. 8b is a plan view schematically showing an example of the first pixel of the display device according to an embodiment of the present specification.

[0172] On the other hand, FIGS. 8a and 8b show an example of the first pixel PX1 among the plurality of pixels PX arranged on the display panel PN of the display device 100 according to an embodiment of the present specification described with reference to FIG. 2.

[0173] On the other hand, the first pixel PX1 shown in FIG. 8a can include the pixel circuit SPC described with reference to FIG. 3 or the pixel circuit SPC_1 described with reference to FIG. 4, and thus, the description overlapping with that described with reference to FIGS. 3 and 4 will not be repeated.

[0174] Also, for the sake of convenience of description, FIGS. 8a and 8b show only the selection circuit, the plurality of light-emitting elements, and the plurality of lenses among the components included in the first pixel PX1. In FIG. 8a, for the sake of convenience of description, only the corresponding relationship is schematically shown by a dotted line for the plurality of lenses.

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

[0176] The first selection circuit SC1 can 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 to the first selection transistor TP1 and the second selection transistor TP2 described with reference to FIGS. 3 and 4, respectively.

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

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

[0179] Accordingly, when the first transistor T1 is turned on in response to a turn-on level selection signal provided from the first selection signal wiring SSL1, a first drive current passing through the first light-emitting element ED1 is formed, and the first light-emitting element ED1 of the first pixel PX1 can emit light.

[0180] When the second transistor T2 is turned on in response to the turn-on level selection signal provided from the second selection signal wiring SSL2, a second drive current passing through the second light emitting element ED2 is formed, and the second light emitting element ED2 of the first pixel PX1 can emit light.

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

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

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

[0184] The first lens region LSA1 and the second lens region LSA2 can provide an image through substantially the same viewing angle. The luminance of the first lens region LSA1 can be controlled by the first drive current generated by the first light emitting element ED1, and the luminance of the second lens region LSA2 can be controlled by the second drive current generated by the second light emitting element ED2.

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

[0186] Each of the first lens LS1 and the second lens LS2 may have a first shape. Each of the first lens LS1 and the second lens LS2 may have a shape that allows light in at least one lateral direction to pass through without being restricted. For example, the planar shape of each of the first lens LS1 and the second lens LS2 located within the first pixel PX1 may have a bar shape extending in one direction. As an example, each of the first lens LS1 and the second lens LS2 may be embodied as the first type of lens 161 described with reference to FIG. 6.

[0187] In such a case, when 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 traveling direction of the corresponding light does not need to be limited to one direction.

[0188] The 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 the 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.

[0189] For example, as shown in FIG. 8b, the planar shape of the first light-emitting region EA1 and the planar shape of the second light-emitting region EA2 may each have a bar shape extending in one direction so as to correspond to the shape of the first lens LS1 and the shape of the second lens LS2, respectively. Also, in this case, the first lens LS1 located on the first lens region LSA1 may have a size larger than the first light-emitting region EA1 included in the first lens region LSA1, and the second lens LS2 located on the second lens region LSA2 may have a size larger than the second light-emitting region EA2 included in the second lens region LSA2. Thereby, 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 can be improved.

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

[0191] Accordingly, when a first driving current is formed within 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 embodied in the first type of 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 a first viewing angle. For example, the provided content (or image) can be shared with people in the surroundings adjacent to the user in one direction. Accordingly, the content provided by the light emitted through the first lens LS1 can be provided in a wide viewing angle mode (Share mode).

[0192] Also, when a second driving current is formed within 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 embodied in the first type of 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 a first viewing angle. For example, the provided content (or image) can be shared with people in the surroundings adjacent to the user in one direction. Accordingly, the content provided by the light emitted through the second lens LS2 can be provided in a wide viewing angle mode (Share mode).

[0193] That is, 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 can be provided at the first viewing angle.

[0194] Here, as described above, the first pixel PX1 can be driven in a third state in which both the first light-emitting element ED1 and the second light-emitting element ED2 emit light. Accordingly, when the first pixel PX1 is driven in the third state, the content can be provided at the first viewing angle by the light generated by the first light-emitting element ED1 and the light generated by the second light-emitting element ED2.

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

[0196] FIG. 9A is a circuit diagram showing an example of a second pixel of a display device according to an embodiment of the present specification. FIG. 9B is a plan view schematically showing an example of a second pixel of a display device according to an embodiment of the present specification.

[0197] On the other hand, FIGS. 9A and 9B show an example of a second pixel PX2 among the plurality of pixels PX arranged on the display panel PN of the display device 100 according to an embodiment of the present specification described with reference to FIG. 2.

[0198] On the other hand, the second pixel PX2 shown in FIG. 9A may include the pixel circuit SPC described with reference to FIG. 3 or the pixel circuit SPC_1 described with reference to FIG. 4, and thus, the description overlapping with the content described with reference to FIGS. 3 and 4 will not be repeated.

[0199] Also, for convenience of explanation, FIGS. 9A and 9B show only a selection circuit, a plurality of light-emitting elements, and a plurality of lenses among the components included in the second pixel PX2. In FIG. 9A, for convenience of explanation, only the corresponding relationship of the plurality of lenses is schematically shown by a dotted line.

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

[0201] The second selection circuit SC2 may include a third transistor T3 and a fourth transistor T4. The third transistor T3 and the fourth transistor T4 in FIG. 9A may be transistors corresponding to the first selection transistor TP1 and the second selection transistor TP2 described with reference to FIGS. 3 and 4, respectively.

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

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

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

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

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

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

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

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

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

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

[0212] In such a case, when the light generated by the third light-emitting element ED3 of the second pixel PX2 is emitted through the third lens LS3, the traveling direction of the corresponding light does not need to be restricted in one direction.

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

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

[0215] The third light-emitting region EA3 defined by the third light-emitting element ED3 of the second pixel PX2 has a shape corresponding to the third lens LS3, and the 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.

[0216] For example, as shown in FIG. 9b, the planar shape of the third light-emitting region EA3 may have a bar shape extending in one direction so as to correspond to the shape of the third lens LS3. Also, in this case, the third lens LS3 located on the third lens region LSA3 may have a size larger than that of the third light-emitting region EA3 included in the third lens region LSA3. Thereby, the efficiency of the light emitted from the third light-emitting region EA3 of the second pixel PX2 may be improved.

[0217] Also, as shown in FIG. 9b, the planar shape of the fourth light-emitting region EA4 may have a circular shape so as to correspond to the shape of the fourth lens LS4. Also, in this case, the fourth lens LS4 located on the fourth lens region LSA4 may have a size larger than that of the fourth light-emitting region EA4 included in the fourth lens region LSA4. For example, the planar shape of the fourth light-emitting region EA4 located within the fourth lens region LSA4 may be concentric with the planar shape of the fourth lens LS4 located on the fourth lens region LSA4. In such a case, the efficiency of the light emitted from the fourth light-emitting region EA4 of the second pixel PX2 may be improved.

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

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

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

[0221] Here, as described above, the second pixel PX2 can be driven in a first state in which the third light-emitting element ED3 emits light, or in a second state in which the fourth light-emitting element ED4 emits light. Accordingly, when the second pixel PX2 is driven in the first state, content can be provided at a first viewing angle by the light generated by the third light-emitting element ED3. Also, when the second pixel PX2 is driven in the second state, content can be provided at a second viewing angle by the light generated by the fourth light-emitting element ED4.

[0222] Thus, in the second region where the second pixel PX2 driven in the first state or the second state is arranged among the plurality of regions of the display panel PN, content in a wide viewing angle mode or content in a narrow viewing angle mode can be provided depending on the driving mode.

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

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

[0225] On the other hand, in FIG. 11, an embodiment in which each of the first pixel PX1 and the second pixel PX2 includes three sub-pixels is shown.

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

[0227] On the one hand, for the sake of convenience of explanation, in FIG. 10, a plurality of rows R1, 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 shown as a plurality of pixel rows and a plurality of pixel columns in which a plurality of first pixels PX1 are arranged on the first region A1.

[0228] Referring to FIGS. 2, 6 to 10, the display panel PN can be partitioned into a plurality of regions A1, A2. For example, as shown in FIG. 10, the display panel PN can be partitioned into two regions A1, A2. As an example, the display panel PN can include a first region A1 and a second region A2 adjacent to the first region A1 in the direction opposite to the first direction DR1.

[0229] Each region A1, A2 included in the display panel PN can include a plurality of pixels in which pixel circuits are respectively arranged. For example, in the first region A1, a plurality of first pixels PX1 are arranged at intervals along the first direction DR1 and the second direction DR2, and in the second region A2, a plurality of second pixels PX2 can be arranged at intervals along the first direction DR1 and the second direction DR2.

[0230] On the one hand, as described above, the first region A1 of the display panel PN is a region provided on the driver's seat side arranged in the front seat of the vehicle described with reference to FIG. 1, and is a region that provides content in the wide viewing angle mode, and the second region A2 of the display panel PN is a region provided on the passenger seat side arranged in the front seat of the vehicle described with reference to FIG. 1, and can be a region that provides content in the wide viewing angle mode or the narrow viewing angle mode depending on the driving mode of the display device 100.

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

[0232] Also, as described with reference to FIGS. 8A and 8B, the first lens LS1 located in the first lens region LSA1 and the second lens LS2 located in the second lens region LSA2 of each of the plurality of first pixels PX1 arranged in the first region A1 can both emit (provide) light at the first viewing angle. As a result, in each of the first mode and the second mode, the video displayed by the plurality of first pixels PX1 arranged in the first region A1 can be provided to the user at the first viewing angle.

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

[0234] Also, as described with reference to FIGS. 9A and 9B, the third lens LS3 located in the third lens region LSA3 of each of the plurality of second pixels PX2 arranged in the second region A2 can provide light at the first viewing angle. As a result, in the first mode, the video displayed by the plurality of second pixels PX2 arranged in the second region A2 can be provided to the user at the first viewing angle. Also, the fourth lens LS4 located in the fourth lens region LSA4 of each of the plurality of second pixels PX2 arranged in the second region A2 can provide light at the second viewing angle. As a result, in the second mode, the video displayed by the plurality of second pixels PX2 arranged in the second region A2 can be provided to the user at the second viewing angle.

[0235] On the other hand, as described above, by having the first pixel PX1 arranged in the first region A1 and the second pixel PX2 arranged in the second region A2 have different lens arrangement structures from each other, a problem may occur in which the boundary between the first region A1 and the second region A2 is visually recognized.

[0236] To describe this in more detail, further referring to FIG. 11, the first pixel PX1 includes a first red sub-pixel RSP1 for implementing red, a first green sub-pixel GSP1 for implementing green, and a first blue sub-pixel BSP1 for implementing blue. The second pixel PX2 can include a second red sub-pixel RSP2 for implementing red, a second green sub-pixel GSP2 for implementing green, and a second blue sub-pixel BSP2 for implementing blue.

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

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

[0239] The first pixel PX1 can include a plurality of first lens regions LSA1 where a first lens LS1 is arranged for each sub-pixel and a plurality of second lens regions LSA2 where a second lens LS2 is arranged for each sub-pixel.

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

[0241] Here, the first sub-lens region LSA1a, the third sub-lens region LSA1b, and the fifth sub-lens region LSA1c where the first lens LS1 of the first pixel PX1 is disposed may be regions included in the first lens region LSA1. That is, since the first lens LS1 having the first shape is disposed on the first sub-lens region LSA1a, the third sub-lens region LSA1b, and the fifth sub-lens region LSA1c of the first pixel PX1, respectively, the images displayed 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.

[0242] Also, the second sub-lens region LSA2a, the fourth sub-lens region LSA2b, and the sixth sub-lens region LSA2c where the second lens LS2 of the first pixel PX1 is disposed may be regions included in the second lens region LSA2. That is, since the second lens LS2 having the first shape is disposed on the second sub-lens region LSA2a, the fourth sub-lens region LSA2b, and the sixth sub-lens region LSA2c of the first pixel PX1, respectively, the images displayed from the second sub-lens region LSA2a, the fourth sub-lens region LSA2b, and the sixth sub-lens region LSA2c of the first pixel PX1 can be provided to the user at the first viewing angle.

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

[0244] The second pixel PX2 can include a plurality of third lens regions LSA3 in which third lenses LS3 are arranged for each sub-pixel and a plurality of fourth lens regions LSA4 in which fourth lenses LS4 are arranged for each sub-pixel.

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

[0246] Here, the seventh sub-lens region LSA3a, the ninth sub-lens region LSA3b, and the eleventh sub-lens region LSA3c in which the third lens LS3 of the second pixel PX2 is arranged may be regions included in the third lens region LSA3. That is, since the third lenses LS3 having the first shape are arranged on the seventh sub-lens region LSA3a, the ninth sub-lens region LSA3b, and the eleventh sub-lens region LSA3c of the second pixel PX2, the images displayed from 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.

[0247] In addition, the eighth sub-lens region LSA4a, the tenth sub-lens region LSA4b, and the twelfth sub-lens region LSA4c where the fourth lens LS4 of the second pixel PX2 is disposed may be regions included in the fourth lens region LSA4. That is, since the fourth lens LS4 having the second shape is disposed on the eighth sub-lens region LSA4a, the tenth sub-lens region LSA4b, and the twelfth sub-lens region LSA4c of the second pixel PX2, respectively, the images displayed from the eighth sub-lens region LSA4a, the tenth sub-lens region LSA4b, and the twelfth sub-lens region LSA4c of the second pixel PX2 can be provided to the user at the second viewing angle.

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

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

[0250] For example, the first lens region LSA1 of the first pixel PX1, such as the first sub-lens region LSA1a, the third sub-lens region LSA1b, and the fifth sub-lens region LSA1c, may be disposed at positions corresponding to the third lens region LSA3 of the first type of lens 161 on the second pixel PX2, such as the seventh sub-lens region LSA3a, the ninth sub-lens region LSA3b, and the eleventh sub-lens region LSA3c, respectively.

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

[0252] The number of the fourth lenses LS4 disposed on the fourth lens region LSA4 for each of the sub-pixels RSP2, GSP2, and BSP2 of the second pixel PX2 and the number of corresponding light-emitting regions may be different. For example, the number of the fourth lenses LS4 located in the tenth sub-lens region LSA4b of the second green sub-pixel GSP2 and the number of the fourth lenses LS4 located in the twelfth sub-lens region LSA4c of the second blue sub-pixel BSP2 may be larger than the number of the fourth lenses LS4 located in the eighth sub-lens region LSA4a of the second red sub-pixel RSP2, respectively. In such a case, the efficiency deviation of the fourth light-emitting element ED4 located on the fourth lens region LSA4 of the second pixel PX2 can be compensated by the number of the fourth lenses LS4 disposed on the fourth lens region LSA4 of each of the second pixels PX2 and the number of corresponding light-emitting regions. However, the number of the fourth lenses LS4 disposed on the fourth lens region LSA4 for each of the sub-pixels RSP2, GSP2, and BSP2 of the second pixel PX2 and the number of corresponding light-emitting regions are not limited thereto, and according to embodiments, the number of the fourth lenses LS4 disposed on the fourth lens region LSA4 for each of the sub-pixels RSP2, GSP2, and BSP2 of the second pixel PX2 and the number of corresponding light-emitting regions may be the same as each other.

[0253] Thus, the first pixel PX1 disposed in the first region A1 and the second pixel PX2 disposed in the second region A2 may have different lens arrangement structures. For example, in the case of the first pixel PX1, lenses having a first shape, for example, the first lens LS1 and the second lens LS2, are disposed in all the lens regions LSA1 and LSA2, while in the case of the second pixel PX2, a third lens LS3 having a first shape is disposed on the third lens region LSA3, and a fourth lens LS4 having a second shape may be disposed on the fourth lens region LSA4.

[0254] As a result, when a plurality of first pixels PX1 disposed in the first region A1 and a plurality of second pixels PX2 disposed in the second region A2 display images with the same luminance, a problem may occur in that the boundary between the first region A1 and the second region A2 is visually recognized due to the difference in the lens arrangement structures between the first pixel PX1 and the second pixel PX2.

[0255] In particular, when the display device 100 is driven in the first mode, as described above, a plurality of first pixels PX1 in the first region A1 are driven in the third state to display an image through the first lens region LSA1 and the second lens region LSA2, while a plurality of second pixels PX2 in the second region A2 are driven in the first state and can display an image only through the third lens region LSA3. Here, in the first mode, since the first region A1 and the second region A2 both provide an image to the user at the same first viewing angle, the images displayed in the first region A1 and the second region A2 can be provided to the user in a form where they are continuously arranged. At this time, when a plurality of first pixels PX1 disposed in the first region A1 and a plurality of second pixels PX2 disposed in the second region A2 display images with the same luminance, since a plurality of first pixels PX1 in the first region A1 are driven in the third state to display an image through the first lens region LSA1 and the second lens region LSA2, the luminance of the first region A1 may be higher than that of the second region A2, which is driven in the first state and can display an image only through the third lens region LSA3. Due to such a luminance difference, a problem may occur in that the boundary between the first region A1 and the second region A2 is visually recognized.

[0256] To solve such problems, the display device 100 according to an embodiment of this specification can control the luminance 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 luminance controller LD generates corrected video data CDATA for controlling the luminance of the display panel PN according to the driving mode of the display device 100 based on the mode signal MODE, and the timing controller TD generates video data RGB provided to the data driving circuit DD based on the corrected video data CDATA, so that the luminance of the video displayed on the display panel PN can be controlled.

[0257] For the display device 100, for example, the luminance controller LD can control the luminance of the display panel PN, for example, the luminance of the first region A1, such that the luminance of the first region A1 increases as it gets farther from the boundary between the first region A1 and the second region A2. Also, the luminance controller LD can control the luminance of the region adjacent to the boundary between the first region A1 and the second region A2 in the first region A1 to have a value substantially the same as or similar to the luminance of the second region A2. In the first mode in which video is provided at the first viewing angle in both the first region A1 and the second region A2, driving the luminance controller LD in this way can minimize the luminance difference between the first region A1 and the second region A2 at the boundary between the first region A1 and the second region A2, so that the problem of the boundary between the first region A1 and the second region A2 being visible can be improved.

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

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

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

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

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

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

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

[0265] For example, in the first mode, in response to the selection signal provided through the third selection signal wiring SSL3, the third transistor T3 included in the second pixel PX2 is turned on, and a first drive current is formed within the second pixel PX2. The light generated by the third light-emitting element ED3 disposed on the third lens region LSA3 of the second pixel PX2 due to the first drive current emits light, and the emitted light is disposed on the third lens region LSA3 and is emitted through the third lens LS3 constituted by the first type of lens 161, whereby content with a first viewing angle can be provided.

[0266] On the other hand, in the first mode, since a selection signal maintained at a turn-off level is provided to the fourth selection signal wiring SSL4, the fourth transistor T4 included in the second pixel PX2 is maintained in a turn-off state, and the fourth light-emitting element ED4 disposed on the fourth lens region LSA4 of the second pixel PX2 can be maintained in a non-light-emitting state. That is, in the second mode, it is not necessary to form a current path of the second drive current within the second pixel PX2.

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

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

[0269] For example, in the second mode, in response to the selection signal provided through the fourth selection signal wiring SSL4, the fourth transistor T4 included in the second pixel PX2 is turned on, and a second drive current is formed within the second pixel PX2. The light generated by the fourth light-emitting element ED4 disposed on the fourth lens region LSA4 of the second pixel PX2 due to the second drive current emits light, and the emitted light is disposed on the fourth lens region LSA4 and is emitted through the fourth lens LS4 constituted by the second type of lens 162, whereby content with a second viewing angle can be provided.

[0270] On the other hand, in the second mode, since a selection signal maintained at the turn-off level is provided to the third selection signal wiring SSL3, the third transistor T3 included in the second pixel PX2 is maintained in the turn-off state, and the third light-emitting element ED3 of the second pixel PX2 can be maintained in the non-light-emitting state. That is, in the second mode, it is not necessary to form a current path of the first drive current in the second pixel PX2.

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

[0272] Regardless of the drive mode, the display device 100 can be controlled such that the luminance of the second region A2 corresponds to the input video data IDATA. For example, the luminance controller LD can generate corrected video data CDATA such that the value of the corrected video data CDATA corresponding to the second region A2 is the same as the value of the input video data IDATA.

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

[0274] Also, as described above, in the first mode in which content in the wide viewing angle mode is provided and in the second mode in which content in the narrow viewing angle mode is provided, the first region A1 of the display panel PN can be driven so that content with the first viewing angle is provided.

[0275] For example, in all cases where the display device 100 is driven in the first mode or the second mode, in response to the selection signal provided from the mode selection unit MD, the first region A1 of the display panel PN can provide the user with content within a first viewing angle.

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

[0277] For example, in each of the first mode and the second mode, in response to the selection signal provided through the first selection signal wiring SSL1, the first transistor T1 included in the first pixel PX1 is turned on to form a first driving current within the first pixel PX1, and in response to the selection signal provided through the second selection signal wiring SSL2, the second transistor T2 included in the first pixel PX1 is turned on to form a second driving current within the first pixel PX1. Further, the light generated by the first light-emitting element ED1 disposed on the first lens region LSA1 of the first pixel PX1 emitting light due to the first driving current is disposed on the first lens region LSA1 and emitted through the first lens LS1 composed of the first type of lens 161, and the light generated by the second light-emitting element ED2 disposed on the second lens region LSA2 of the first pixel PX1 emitting light due to the second driving current is disposed on the second lens region LSA2 and emitted through the second lens LS2 composed of the first type of lens 161, whereby content within a first viewing angle can be provided.

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

[0279] Further, the display device 100 can control the luminance of the area adjacent to the boundary between the first area A1 and the second area A2 in the first area A1 to have a value substantially the same as or similar to the luminance of the second area A2.

[0280] For more specific description, referring to FIG. 12, in the first mode, the display device 100 can control the luminance of the first lens area LSA1 of the first pixel PX1 arranged on the first area A1 to correspond to the input video data IDATA. For example, the luminance controller LD can generate the corrected video data CDATA such that the value of the corrected video data CDATA corresponding to the first lens area LSA1 of each of the plurality of first pixels PX1 arranged on the first area A1 is the same as the value of the input video data IDATA. Thereby, in the first mode, the first lens area LSA1 of the first pixel PX1 arranged on the first area A1 can emit light at the reference luminance L0.

[0281] Also, in the first mode, the luminance of the second lens area LSA2 of the first pixel PX1 arranged on the first area A1 can increase as it is farther from the boundary between the first area A1 and the second area A2.

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

[0283] Also, the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the second column C2 adjacent to the first column C1 along the first direction DR1 on the first area A1 can emit light at the second luminance L2 that is higher than the first luminance L1. Here, the second luminance L2 may be lower than the reference luminance L0.

[0284] Similarly, the second lens area LSA2 of each of the plurality of first pixels PX1 arranged on the third column C3 adjacent to the second column C2 along the first direction DR1 on the first area A1 can emit light at the third luminance L3 that is higher than the second luminance L2. Here, the third luminance L3 may be lower than the reference luminance L0.

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

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

[0287] Also, each second lens region LSA2 of a plurality of first pixels PX1 disposed on the mth column Cm that is farthest from the boundary between the first region A1 and the second region A2 on the first region A1 can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of each second lens region LSA2 of a plurality of first pixels PX1 disposed on the pixel column, for example, the mth column Cm, that is farthest from the boundary between the first region A1 and the second region A2 among the plurality of first pixels PX1 disposed on the first region A1 to correspond to the input video data IDATA.

[0288] In this way, the display device 100 can control the luminance of each second lens region LSA2 of a plurality of first pixels PX1 disposed on the first region A1 to increase as it gets farther from the boundary between the first region A1 and the second region A2 in the first mode, for example, as it goes in the first direction DR1. For example, the display device 100 can control the luminance of each second lens region LSA2 of a plurality of first pixels PX1 disposed on the first region A1 to increase as it goes from the first column C1 to the mth column Cm. Thereby, when the video is displayed in the first mode, the problem of the boundary between the first region A1 and the second region A2 being visible can be minimized.

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

[0290] Thereby, the luminance of each of the plurality of first pixels PX1 disposed on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 may have a value substantially the same as or similar to the luminance of each of the plurality of second pixels PX2 disposed on the second region A2, for example, the reference luminance L0. Thereby, when an image is displayed in the first mode, the problem that the boundary between the first region A1 and the second region A2 is visually recognized can be more effectively improved.

[0291] However, the embodiments of the present specification are not limited thereto, and the second lens region LSA2 of each of the plurality of first pixels PX1 disposed on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 may be non-emissive.

[0292] Also, as described with reference to FIG. 11, the second lens regions LSA2 of the plurality of first pixels PX1 disposed on the first region A1 can be disposed at positions corresponding to the fourth lens region LSA4 where the fourth lens LS4 of the second type of lens 162 is disposed by the plurality of second pixels PX2 disposed on the second region A2 in terms of the lens arrangement structure. Thus, when the display device 100 controls the luminance of the plurality of first pixels PX1 disposed on the first region A1 to increase as it moves farther from the boundary between the first region A1 and the second region A2 in the first mode, for example, as it moves in the first direction DR1, by controlling the luminance of the second lens region LSA2 of the first pixel PX1 corresponding to the fourth lens region LSA4 of the second region A2 which is non-emissive in the first mode in terms of the lens arrangement structure, the problem that the boundary between the first region A1 and the second region A2 is visually recognized can be more effectively improved.

[0293] The display device 100 can control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 disposed on the first region A1 to increase linearly as it moves farther from the boundary between the first region A1 and the second region A2 in the first mode, for example, as it moves in the first direction DR1. Thus, the problem that the luminance change on the first region A1, for example, the luminance change due to the first direction DR1 is visually recognized by the user can be minimized.

[0294] On the other hand, as described above, the display device 100 can control the luminance of the first region A1 to correspond to the input video data IDATA in the second mode.

[0295] For example, referring to FIG. 13, in the second mode, the display device 100 can control the luminance of the first lens region LSA1 and the luminance of the second lens region LSA2 of the first pixel PX1 disposed on the first region A1 to correspond to the input video data IDATA, respectively. For example, the luminance controller LD can generate the corrected video data CDATA such that the values of the corrected video data CDATA corresponding to the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 disposed on the first region A1 are the same as the values of the input video data IDATA. Thereby, in the second mode, the first lens region LSA1 of the first pixel PX1 disposed on the first region A1 can emit light at the reference luminance L0, and the second lens region LSA2 of the first pixel PX1 disposed on the first region A1 can emit light at the reference luminance L0.

[0296] On the other hand, in such a second mode, since all of the first lens region LSA1 and the second lens region LSA2 of the first pixel PX1 disposed on the first region A1 emit light at the reference luminance L0, a luminance difference may occur between the video displayed in the first region A1 and the video displayed in the second region A2. However, despite such a luminance difference, in the second mode, since the video is displayed at the first viewing angle on the first region A1 and the video is displayed at the second viewing angle on the second region A2, there is no problem that the boundary is substantially visually recognized by the user.

[0297] As described above, the display device 100 according to an embodiment of the present specification can display the content at the first viewing angle on the display panel PN in the first mode and display the content at the second viewing angle on at least a part of the region (second region) of the display panel PN in the second mode according to the drive mode. Here, the display device 100 according to an embodiment of the present specification can control the luminance of the first region A1 of the display panel PN such that the luminance of the first region A1 increases as it is farther from the boundary between the first region A1 and the second region A2 that provides the content at the first viewing angle in the first mode according to the drive mode. Further, the display device 100 can control the luminance of the region adjacent to the boundary between the first region A1 and the second region A2 in the first region A1 to have a value substantially the same as or similar to the luminance of the second region A2.

[0298] Accordingly, the problem that the boundary between the first region A1 and the second region A2 is visible can be improved.

[0299] On the other hand, in the above, it has been described based on the premise that the display device 100 controls the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the first region A1 in the first mode, and controls the luminance of the plurality of first pixels PX1 arranged throughout the first region A1. However, the embodiments of the present specification are not limited thereto.

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

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

[0302] In FIG. 14, an embodiment is shown in which the display device 100 controls the luminance of a partial region of the first region A1, for example, the third region A3, in the first mode.

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

[0304] Referring to FIG. 14, the display device 100 can control the luminance of the display panel PN, for example, the first region A1, such that the luminance of a partial region of the first region A1, for example, the third region A3, increases as it gets farther from the boundary between the first region A1 and the second region A2 in the first mode. For example, in the first mode, the display device 100 can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the third region A3, which is adjacent to the second region A2 in the first region A1, to increase as it gets farther from the boundary between the first region A1 and the second region A2.

[0305] Further, the display device 100 can control the luminance of the region adjacent to the boundary between the first region A1 and the second region A2 in the third region A3 to have a value substantially the same as or similar to the luminance of the second region A2.

[0306] Accordingly, in the first mode, the luminance of the first pixel PX1 disposed on the third region A3 adjacent to the second region A2 in the first region A1 has a value substantially the same as the luminance of the second region A2 at the portion closest to the second region A2, and can increase as it gets farther from the boundary between the first region A1 and the second region A2.

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

[0308] Also, each of the second lens regions LSA2 of the plurality of first pixels PX1 disposed on the second column C2 adjacent to the first column C1 along the first direction DR1 on the third region A3 can emit light at a seventh luminance L7 higher than the sixth luminance L6. Here, the seventh luminance L7 may be lower than the reference luminance L0.

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

[0310] Also, each of the second lens regions LSA2 of the plurality of first pixels PX1 disposed on the remaining region of the first region A1 excluding the third region A3, for example, the fourth region A4, can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of each of the second lens regions LSA2 of the plurality of first pixels PX1 disposed on the remaining region of the first region A1 excluding the third region A3, for example, the fourth region A4, to correspond to the input video data IDATA.

[0311] In this way, in the first mode, the display device 100 can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the third region A3 adjacent to the second region A2 in the first region A1 to increase as it goes farther from the boundary between the first region A1 and the second region A2, for example, as it goes in the first direction DR1. For example, the display device 100 can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the third region A3 to increase as it goes from the first column C1 to the third column C3. Thereby, when an image is displayed in the first mode, the problem that the boundary between the first region A1 and the second region A2 is visually recognized can be minimized.

[0312] Substantially the same as or similar to that described with reference to FIG. 12, the sixth luminance L6 of the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the third region A3 may have a luminance corresponding to a substantially black image. For example, the sixth luminance L6 may have a value of 0. Thereby, when an image is displayed in the first mode, the problem that the boundary between the first region A1 and the second region A2 is visually recognized can be more effectively improved. However, the embodiments of this specification are not limited thereto, and the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the third region A3 may be non-emissive.

[0313] Also, substantially the same as or similar to that described with reference to FIG. 12, the display device 100 can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the third region A3 to increase linearly as it goes farther from the boundary between the first region A1 and the second region A2, for example, as it goes in the first direction DR1 in the first mode. Thereby, the problem that the luminance change on the third region A3, for example, the luminance change in the first direction DR1, is visually recognized by the user can be minimized.

[0314] On the one hand, in FIG. 14, the description was based on the fact that the third region A3 adjacent to the second region A2 in the first region A1 includes the first to third columns C1, C2, and C3 which are three pixel columns. However, this is merely illustrative for convenience of explanation, and the embodiments of the present specification are not limited thereto. For example, the third region A3 may be designed to include two or fewer pixel columns, or may be designed to include four or more pixel columns.

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

[0316] In FIG. 15, an embodiment is shown in which the display device 100 controls the luminance of the first lens region LSA1 and the second lens region LSA2 of the first pixel PX1 disposed on the first region A1 in the first mode.

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

[0318] Referring to FIG. 15, the display device 100 can control the luminance of the display panel PN, for example, the luminance of the first region A1, so that the luminance of the first region A1 increases as it moves farther from the boundary between the first region A1 and the second region A2 in the first mode. For example, in the first mode, the display device 100 can control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 disposed on the first region A1 to increase as it moves farther from the boundary between the first region A1 and the second region A2.

[0319] Further, the display device 100 can control the luminance of the region adjacent to the boundary between the first region A1 and the second region A2 in the first region A1 to have a value substantially the same as or similar to the luminance of the second region A2.

[0320] As a result, in the first mode, the luminance of the first pixel PX1 disposed on the first region A1 has a value substantially the same as the luminance of the second region A2 at the portion closest to the second region A2, and can increase as it gets farther from the boundary between the first region A1 and the second region A2.

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

[0322] Also, the first lens regions LSA1 and the second lens regions LSA2 of the plurality of first pixels PX1 disposed on the second column C2 adjacent to the first column C1 along the first direction DR1 on the first region A1 can emit light at a tenth luminance L10 higher than the ninth luminance L9, respectively. Here, the tenth luminance L10 may be lower than the reference luminance L0.

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

[0324] Similarly, the first lens regions LSA1 and the second lens regions LSA2 of the plurality of first pixels PX1 disposed on the fourth column C4 adjacent to the third column C3 along the first direction DR1 on the first region A1 can emit light at a twelfth luminance L12 higher than the eleventh luminance L11, respectively. Here, the twelfth luminance L12 may be lower than the reference luminance L0.

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

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

[0327] In this way, in the first mode, the display device 100 can control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first region A1 to increase as the distance from the boundary between the first region A1 and the second region A2 increases, for example, as it goes in the first direction DR1. For example, the display device 100 can control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first region A1 to increase as it goes from the first column C1 to the m-th column Cm. Thereby, when the video is displayed in the first mode, the problem of the boundary between the first region A1 and the second region A2 being visually recognized can be minimized.

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

[0329] As a result, the luminance of each of the plurality of first pixels PX1 disposed on the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 may have a value substantially the same as or similar to the luminance of each of the plurality of second pixels PX2 disposed on the second region A2, for example, the reference luminance L0. Thereby, when the video is displayed in the first mode, the problem that the boundary between the first region A1 and the second region A2 is visually recognized can be more effectively improved.

[0330] Also, substantially the same as or similar to that described with reference to FIG. 12, in the first mode, the display device 100 can control the luminance of the first lens region LSA1 and the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 disposed on the first region A1 to increase linearly as the distance from the boundary between the first region A1 and the second region A2 increases, for example, as it goes in the first direction DR1. Thereby, the problem that the luminance change on the first region A1, for example, the luminance change due to the first direction DR1, is visually recognized by the user can be minimized.

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

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

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

[0334] Referring to FIG. 16, in the first mode, the display device 100 can control the luminance of the display panel PN, for example, a part of the first region A1, such as the luminance of the third region A3, to increase as it gets farther from the boundary between the first region A1 and the second region A2. For example, in the first mode, the display device 100 can control the luminance of the first lens region LSA1 and the second lens region LSA2 of each of the plurality of first pixels PX1 disposed on the third region A3, which is adjacent to the second region A2 among the first region A1, to increase as it gets farther from the boundary between the first region A1 and the second region A2.

[0335] Further, the display device 100 can control the luminance of the region adjacent to the boundary between the first region A1 and the second region A2 in the third region A3 to have a value substantially the same as or similar to the luminance of the second region A2.

[0336] As a result, in the first mode, the luminance of the first pixel PX1 disposed on the third region A3 adjacent to the second region A2 in the first region A1 can have a value substantially the same as the luminance of the second region A2 at the portion closest to the second region A2, and can increase as it gets farther from the boundary between the first region A1 and the second region A2.

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

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

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

[0340] Also, the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the remaining region of the first region A1 excluding the third region A3 can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of the first lens regions LSA1 and the second lens regions LSA2 of the plurality of first pixels PX1 arranged in the remaining region of the first region A1 excluding the third region A3, for example, the fourth region A4, on the first region A1 to correspond to the input video data IDATA.

[0341] Thus, in the first mode, the display device 100 can control the luminance of the first lens regions LSA1 and the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the third region A3 adjacent to the second region A2 in the first region A1 to increase as the distance from the boundary between the first region A1 and the second region A2 increases, for example, as going in the first direction DR1. For example, the display device 100 can control the luminance of the first lens regions LSA1 and the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the third region A3 to increase as going from the first column C1 to the third column C3. Thereby, when an image is displayed in the first mode, the problem that the boundary between the first region A1 and the second region A2 is visually recognized can be minimized.

[0342] Similar to or substantially the same as described with reference to FIG. 15, the 14th luminance L14 of each of the first lens regions LSA1 and the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the first column C1 that is most adjacent to the boundary between the first region A1 and the second region A2 on the third region A3 may have a luminance substantially corresponding to half of the reference luminance L0. Thereby, when an image is displayed in the first mode, the problem that the boundary between the first region A1 and the second region A2 is visually recognized can be more effectively improved.

[0343] Also, similar to or substantially the same as described with reference to FIG. 12, in the first mode, the display device 100 can be controlled such that the luminance of each of the first lens regions LSA1 and the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the third region A3 increases linearly as it gets farther from the boundary between the first region A1 and the second region A2, for example, as it goes in the first direction DR1. Thereby, the problem that the luminance change on the third region A3, for example, the luminance change due to the first direction DR1, is visually recognized by the user can be minimized.

[0344] On the other hand, in FIG. 16, the description is based on the premise that the third region A3 adjacent to the second region A2 in the first region A1 includes the first to third columns C1, C2, and C3 which are three pixel columns, but this is merely exemplary for convenience of explanation, and the embodiments of the present specification are not limited thereto. For example, the third region A3 may be designed to include two or fewer pixel columns or four or more pixel columns.

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

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

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

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

[0349] The display device 100 can control, in the first mode, the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 in units of pixel rows so that the luminance increases as it moves farther from the boundary between the first region A1 and the second region A2.

[0350] For example, in the first mode, the display device 100 can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in the odd-numbered rows, for example, the first row R1, among the plurality of first pixels PX1 arranged on the odd-numbered columns, for example, the first column C1 and the third column C3, so that the luminance increases as it moves farther from the boundary between the first region A1 and the second region A2.

[0351] Also, in the first mode, the display device 100 can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in the even-numbered rows, for example, the second row R2, among the plurality of first pixels PX1 arranged on the even-numbered columns, for example, the second column C2 and the fourth column C4, so that the luminance increases as it moves farther from the boundary between the first region A1 and the second region A2.

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

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

[0354] Also, the second lens region LSA2 of the first pixel PX1 disposed in the even-numbered rows among the plurality of first pixels PX1 disposed on the second column C2 adjacent to the first column C1 along the first direction DR1 on the first region A1, for example, the second row R2, can emit light at a second luminance L2 higher than the first luminance L1. Here, the second luminance L2 may be lower than the reference luminance L0.

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

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

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

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

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

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

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

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

[0363] As described above, in the first mode, the display device 100 can control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first region A1 in units of pixel rows to increase as it goes farther from the boundary between the first region A1 and the second region A2, for example, as it goes in the first direction DR1. For example, the display device 100 can control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the odd-numbered rows of the odd-numbered columns, for example, the first column C1 and the third column C3, to increase as it goes from the first column C1 to the m-th column Cm, and can control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the even-numbered rows of the even-numbered columns, for example, the second column C2 and the fourth column C4, to increase. As an example, in the first mode, the display device 100 can control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first region A1 in a zigzag pattern to increase as it goes in the first direction DR1 from the boundary between the first region A1 and the second region A2.

[0364] Accordingly, when an image is displayed in the first mode, the problem of the boundary between the first region A1 and the second region A2 being visible can be minimized.

[0365] Substantially the same as or similar to that described with reference to FIG. 12, the first luminance L1 of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the odd-numbered rows of the first column C1 that is closest to the boundary between the first region A1 and the second region A2 on the first region A1 can have a luminance corresponding to a substantially black image, for example, a value of 0. Accordingly, when an image is displayed in the first mode, the problem of the boundary between the first region A1 and the second region A2 being visible can be more effectively improved. However, the embodiments of the present specification are not limited thereto, and the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the odd-numbered rows of the first column C1 that is closest to the boundary between the first region A1 and the second region A2 on the first region A1 can be non-emissive.

[0366] Also, similar to or substantially the same as described with reference to FIG. 12, in the first mode, the display device 100 can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 disposed on the first region A1 to linearly increase as it goes farther from the boundary between the first region A1 and the second region A2, for example, as it goes in the first direction DR1. Thereby, the problem that the luminance change on the first region A1, for example, the luminance change in the first direction DR1, is visually recognized by the user can be minimized.

[0367] On the other hand, in FIG. 17, the description has been made based on the control such that as the display device 100 goes farther from the boundary between the first region A1 and the second region A2 in the first mode, the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 disposed in the odd-numbered rows among the plurality of first pixels PX1 disposed on the odd-numbered columns increases, and the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 disposed in the even-numbered rows among the plurality of first pixels PX1 disposed on the even-numbered columns increases. However, the present invention is not limited thereto. For example, as the display device 100 goes farther from the boundary between the first region A1 and the second region A2 in the first mode, the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 disposed in the even-numbered rows among the plurality of first pixels PX1 disposed on the odd-numbered columns increases, and the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 disposed in the odd-numbered rows among the plurality of first pixels PX1 disposed on the even-numbered columns increases, and the control can be performed.

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

[0369] FIG. 18 shows an embodiment in which the display device 100 alternately controls the luminance of the second lens regions LSA2 of the first pixels PX1 disposed on a part of the first region A1, for example, the third region A3, in pixel row units in the first mode.

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

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

[0372] The display device 100, for example, the luminance controller LD, can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged on the third region A3 in units of pixel rows so that the luminance increases as it moves farther from the boundary between the first region A1 and the second region A2 in the first mode.

[0373] For example, the display device 100, for example, the luminance controller LD, can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in the odd-numbered rows, for example, the first row R1, among the plurality of first pixels PX1 arranged on the odd-numbered columns, for example, the first column C1 and the third column C3, on the third region A3 so that the luminance increases as it moves farther from the boundary between the first region A1 and the second region A2 in the first mode.

[0374] In addition, the display device 100 can control the luminance of the second lens regions LSA2 of the plurality of first pixels PX1 arranged in the even-numbered rows, for example, the second row R2, among the plurality of first pixels PX1 arranged on the even-numbered columns, for example, the second column C2, on the third region A3 so that the luminance increases as it moves farther from the boundary between the first region A1 and the second region A2 in the first mode.

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

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

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

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

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

[0380] Also, the second lens region LSA2 of each of the plurality of first pixels PX1 disposed on the remaining region of the first region A1 excluding the third region A3 can emit light at the reference luminance L0. That is, the display device 100 can control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 disposed on the remaining region of the first region A1 excluding the third region A3, for example, the fourth region A4, to correspond to the input video data IDATA.

[0381] In this way, in the first mode, the display device 100 can control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the third region A3 in pixel row units to increase as it goes farther from the boundary between the first region A1 and the second region A2, for example, as it goes in the first direction DR1. As a result, when an image is displayed in the first mode, the problem of the boundary between the first region A1 and the second region A2 being visible can be minimized.

[0382] Substantially the same or similar to that described with reference to FIG. 12, the sixth luminance L6 of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the odd-numbered rows, for example, the first row R1, of the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 may have a luminance corresponding to a substantially black image, for example, a value of 0. As a result, when an image is displayed in the first mode, the problem of the boundary between the first region A1 and the second region A2 being visible can be more effectively improved. However, the embodiments of this specification are not limited thereto, and the second lens regions LSA2 of each of the plurality of first pixels PX1 arranged on the odd-numbered rows, for example, the first row R1, of the first column C1 closest to the boundary between the first region A1 and the second region A2 on the first region A1 may be non-emissive.

[0383] Also, substantially the same or similar to that described with reference to FIG. 12, the display device 100 can control the luminance of the second lens region LSA2 of each of the plurality of first pixels PX1 arranged on the first region A1 to increase linearly as it goes farther from the boundary between the first region A1 and the second region A2, for example, as it goes in the first direction DR1 in the first mode. As a result, the problem that the luminance change on the first region A1, for example, the luminance change due to the first direction DR1, is visible to the user can be minimized.

[0384] On the one hand, in FIG. 18, it was described based on the criterion that as the display device 100 moves farther from the boundary between the first region A1 and the second region A2 in the first mode, the luminance of the second lens region LSA2 of the odd-numbered first pixels PX1 arranged in the odd-numbered rows among the plurality of first pixels PX1 arranged on the third region A3 increases, and the luminance of the second lens region LSA2 of the even-numbered first pixels PX1 arranged in the even-numbered rows among the plurality of first pixels PX1 arranged on the even-numbered columns on the third region A3 increases. However, the present invention is not limited thereto. For example, as the display device 100 moves farther from the boundary between the first region A1 and the second region A2 in the first mode, the luminance of the second lens region LSA2 of the even-numbered first pixels PX1 arranged in the odd-numbered rows among the plurality of first pixels PX1 arranged on the third region A3 increases, and the luminance of the second lens region LSA2 of the odd-numbered first pixels PX1 arranged in the even-numbered rows among the plurality of first pixels PX1 arranged on the even-numbered columns on the third region A3 can be increased.

[0385] On the other hand, in FIG. 18, it was described based on the criterion that the third region A3 adjacent to the second region A2 in the first region A1 includes the first to third columns C1, C2, and C3, which are three pixel columns. However, this is merely illustrative for the convenience of explanation, and the embodiments of the present specification are not limited thereto. For example, the third region A3 may be designed to include two or fewer pixel columns, or may be designed to include four or more pixel columns.
