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. Display devices include not only electro-optical panels that simply transmit visual information in one direction, but also various electronic devices that require higher technologies 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 may 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 area that provides content with a wide viewing angle and a second area that provides content with a wide or narrow viewing angle.

[0005] Another problem to be solved by this specification is to provide a display device that can improve power consumption due to increased brightness.

[0006] 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

[0007] A display device according to an embodiment of the present specification may include a display panel partitioned into a first region including a plurality of first pixels and a plurality of second pixels, and a second region adjacent to the first region in a direction opposite to a first direction and including a plurality of third pixels. Each of the plurality of first pixels includes a first light-emitting element, a second light-emitting element, a first optical member that emits light generated from the first light-emitting element at a first viewing angle, and a second optical member that emits light generated from the second light-emitting element at the first viewing angle. Each of the plurality of second pixels includes a third light-emitting element, a fourth light-emitting element, a third optical member that emits light generated from the third light-emitting element at the first viewing angle, and a fourth optical member that emits light generated from the fourth light-emitting element at a second viewing angle lower than the first viewing angle. Each of the plurality of third pixels may include a fifth light-emitting element, a sixth light-emitting element, a fifth optical member that emits light generated from the fifth light-emitting element at the first viewing angle, and a sixth optical member that emits light generated from the sixth light-emitting element at the second viewing angle. The pixel density of the plurality of second pixels disposed on the first region may vary by region.

[0008] Specific matters of other embodiments are included in the detailed description and the drawings.

Effects of the Invention

[0009] This specification can provide content at a wide viewing angle in the first region of the display panel and can provide content at a wide viewing angle or a narrow viewing angle in the second region.

[0010] This specification can minimize the problem that the boundary between the first region and the second region is visible by further arranging pixels having the same lens structure as the pixels arranged on the second region on the first region.

[0011] This specification drives the first region so that all of the plurality of light-emitting elements included in each of the plurality of pixels disposed on the first region that provides content at a wide viewing angle emit light, thereby providing content at a wide viewing angle and at the same time increasing the luminance based on what has the same data signal written therein.

[0012] The power consumption for increasing the brightness can be improved in this specification.

[0013] The effects according to the present invention are not limited by the contents illustrated above, and more various effects are included in the present invention.

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 muddy the gist of the present specification, the detailed description thereof is omitted. When terms such as "including", "having", "being made" mentioned in the present specification are used, unless "only" is used, other parts can be added.

[0019] What an element or layer is referred to as "on" another element or layer includes both the case where it is immediately above the other element and the case where another layer or another element is interposed in the middle.

[0020] 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 concept of this specification.

[0022] The area and thickness of each configuration shown in the drawings are shown for convenience of explanation, and this specification is not necessarily limited to the area and thickness of the shown configuration.

[0023] The respective features of the various embodiments of this specification can be partially or wholly combined or combined with each other, various technical linkages and drives are possible, and each embodiment may be implemented independently of each other or may be implemented together in a related relationship.

[0024] Hereinafter, this specification will be described with reference to the drawings.

[0025] FIG. 1 is an exemplary diagram of a display device according to an embodiment of this specification.

[0026] Referring to FIG. 1, the display device 100 can be disposed at least partially on 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).

[0027] 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 vehicle operation information (e.g., current speed of the vehicle, remaining fuel level, driving distance), information about vehicle components (e.g., degree of damage to the vehicle's tires), etc.

[0028] 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 passengers riding in the passenger seat. Any of the driver and passengers of the vehicle can use the display device 100.

[0029] The display device 100 shown in FIG. 1 may show only a part thereof. The display device 100 shown in FIG. 1 may show the display panel among the 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. The configurations of the display device 100 other than the part shown in FIG. 1 can be implemented inside the vehicle (or at least partially).

[0030] FIG. 2 is a functional block diagram of a display device according to an embodiment of the present specification.

[0031] In one embodiment of the present specification, an electroluminescent display device can be applied to the 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 can be used.

[0032] Referring to FIG. 2, the display device 100 can include a display panel PN, a data driving circuit DD, a gate driving circuit GD, and a timing controller TD. The display device 100 can further include a mode controller MS and a mode selector MD.

[0033] The display panel PN can generate an image provided to a 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.

[0034] The plurality of pixels PX can include a first pixel, a second pixel, and a third pixel arranged according to regions of the display panel PN. Details of the first pixel, the second pixel, and the third pixel and their arrangement relationship will be described later with reference to FIGS. 8 to 12.

[0035] 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 can include a plurality of data wirings DL and a plurality of gate wirings GL.

[0036] 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.

[0037] The plurality of data wirings DL are arranged in the column direction and can include a plurality of wirings connected to the pixels PX arranged in one column direction. The plurality of gate wirings GL are arranged in the row direction and can include a plurality of wirings connected to the pixels PX arranged in one row direction.

[0038] Also, the plurality of selection signal wirings SSL can be arranged in the row direction and can include a plurality of wirings connected to the pixels PX arranged in one row direction.

[0039] The plurality of selection signal wirings SSL can include the first to sixth selection signal wirings. Here, the first and second selection signal wirings are selection signal wirings commonly connected to the first pixel included in the plurality of pixels PX, the third and fourth selection signal wirings are selection signal wirings commonly connected to the second pixel included in the plurality of pixels PX, and the fifth and sixth selection signal wirings can be selection signal wirings commonly connected to the third pixel included in the plurality of pixels PX. A detailed description of the connection relationship of the first to sixth selection signal wirings will be described later with reference to FIGS. 8 to 12.

[0040] 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 the power wiring connecting the power supply unit and the display panel PN. According to an embodiment, the power supply unit can provide power to the data driving circuit DD and the gate driving circuit GD. The data driving circuit DD and the gate driving circuit GD can be driven based on the power provided from the power supply unit.

[0041] As an example, the data driving circuit DD can apply a data signal to each pixel PX through a plurality of data wirings DL, the gate driving circuit GD can apply a gate signal to each pixel PX through a plurality of gate wirings GL, and the power supply unit can supply a power supply voltage to each pixel PX through a power supply voltage supply wiring.

[0042] 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 digital video data input from the outside to match the resolution of the display panel PN and supply it to the data driving circuit DD.

[0043] The data driving circuit DD can convert the digital video data input from the timing controller TD based on a data control signal into an analog data voltage and supply it to a plurality of data wirings DL.

[0044] The gate driving circuit GD can generate a scan signal and a light emission signal (or a light emission control signal) based on a 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 each pixel 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 each pixel and supply it to the light emission signal wiring.

[0045] 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 of parts and arranged on at least two side surfaces of the display panel PN respectively.

[0046] The mode controller MS can control the mode selection unit MD. For example, the mode controller MS can generate a mode selection signal MSS for controlling the mode selection unit MD based on a mode signal 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 selection signals to a plurality of selection signal wirings SSL in response to the mode selection signal MSS.

[0047] The display panel PN can include a display area and a non-display area surrounding the display area.

[0048] 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.

[0049] 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 sub-pixels for further implementing a specific color (e.g., white).

[0050] The area where blue is implemented in the pixel PX can be referred to as a blue sub-pixel, the area where red is implemented as a red sub-pixel, and the area where green is implemented as a green sub-pixel.

[0051] 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.

[0052] 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".

[0053] For example, the first type of lens may be disposed in a lens region that provides light to a first range to form a first viewing angle, and the second type of lens may be disposed in a lens region that provides light to a second range to form a second viewing angle. The first range may correspond to a range wider than the second range. Thus, the first type of lens and the second type of lens can limit the viewing angles of the respective plurality of pixels PX.

[0054] 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.

[0055] The non-display area may be disposed along the periphery of the display area. Various components for driving the pixel circuit disposed in the pixel PX may be disposed in the non-display area. For example, at least a part of the gate driving circuit GD may be disposed in the non-display area. The non-display area may be referred to as a bezel area.

[0056] The display panel PN may be partitioned 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 and a plurality of second pixels among the plurality of pixels PX are disposed, and a second area where a plurality of third pixels among the plurality of pixels PX are disposed. Each of the plurality of first pixels, the plurality of second pixels disposed in the first area, and the plurality of third pixels disposed in the second area can include the same pixel circuit.

[0057] For example, each of the plurality of first pixels, the plurality of second pixels disposed in the first area of the display panel PN, and the plurality of third pixels disposed in the second area can include a driving circuit, a selection circuit, a first type of light-emitting element and a second type of light-emitting element that emit the same color.

[0058] 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.

[0059] Further, the selection circuit may be a circuit for controlling to generate either the first drive current passing through the first type of light-emitting element or the second drive current passing through the second type of light-emitting element based on the selection signal provided from the mode selection unit MD. In other words, by the control of the selection circuit, either the current path of the first drive current is formed and the first type of light-emitting element emits light, or the current path of the second drive current is formed and the second type of light-emitting element emits light. However, it is not limited thereto, and the selection circuit may also be defined as being included in the drive circuit.

[0060] 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.

[0061] The selection circuit may 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 such control of the selection circuit, the current path of the first drive current and the current path of the second drive current are respectively formed, and both the first type of light-emitting element and the second type of light-emitting element can emit light.

[0062] 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 both 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.

[0063] Each of the plurality of first pixels disposed in the first region of the display panel PN can include two first-type lenses that refract light from the first-type light-emitting element and the second-type light-emitting element in a specific direction, for example, the first lens and the second lens. For example, the light generated from the first-type light-emitting element included in each of the plurality of first pixels disposed in the first region of the display panel PN is refracted in a specific direction through the first lens embodied in the first-type lens, and the light generated from the second-type light-emitting element can be refracted in a specific direction through the second lens embodied in the first-type lens.

[0064] Each of the plurality of second pixels disposed in the first region of the display panel PN and the plurality of third pixels disposed in the second region can include a first-type lens that refracts light from the first-type light-emitting element in a specific direction, for example, the third lens or the fifth lens, and a second-type lens that refracts light from the second-type light-emitting element in a specific direction, for example, the fourth lens or the sixth lens. For example, the light generated from the first-type light-emitting element included in each of the plurality of second pixels disposed in the first region of the display panel PN is refracted in a specific direction through the third lens embodied in the first-type lens, and the light generated from the second-type light-emitting element included in each of the plurality of second pixels disposed in the first region of the display panel PN can be refracted in a specific direction through the fourth lens embodied in the second-type lens. As another example, the light generated from the first-type light-emitting element included in each of the plurality of third pixels disposed in the second region of the display panel PN is refracted in a specific direction through the fifth lens embodied in the first-type lens, and the light generated from the second-type light-emitting element included in each of the plurality of third pixels disposed in the second region of the display panel PN can be refracted in a specific direction through the sixth lens embodied in the second-type lens.

[0065] 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 to third pixels disposed in the first region and the second region will be described later with reference to FIGS. 8 to 18.

[0066] According to the embodiment, each region of the display panel PN is arranged to cross the driver's seat and the passenger seat arranged in front 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 arranged in front of the vehicle, and provides information such as running speed, RPM, engine temperature, fuel quantity, etc. The second region of the display panel PN is a region provided on the passenger seat side arranged in front of the vehicle, and can provide entertainment functions and seat information for the passenger getting on the passenger seat. On the other hand, the first region of the display panel PN can further include a center fascia region arranged between the driver's seat and the passenger seat. However, such region division is for convenience of explanation, and the first region and the second region on the display panel PN can be defined variously by design.

[0067] On the other hand, when the display panel PN is used in the vehicle described with reference to FIG. 1, according to the user's request, the view of at least some of the plurality of regions included in the display panel PN needs to be restricted. For example, in the case of the video displayed in the second region that provides entertainment functions and seat information for the passenger getting on the passenger seat, since it may interfere with the driver's vehicle operation, it may be necessary that the view of the video displayed in the second region is restricted according to the user's request.

[0068] More specifically, referring to FIG. 2, the display device 100 can control the view 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.

[0069] The mode controller MS can generate a mode selection signal MSS that enables the display panel PN to be controlled in a first mode or a second mode according to the driving mode of the display device 100, 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 a wide viewing angle mode (Share mode), and the second mode corresponds to a mode in which at least a part of a plurality of regions of the display panel PN, for example, the second region among the first region and the second region, is driven in a narrow viewing angle mode (Private mode).

[0070] 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. 13a and 13b.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] The driving circuit DC can include a driving transistor DT, a switching transistor ST, and a first capacitor C1.

[0075] 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.

[0076] The switching transistor ST is connected to the gate wiring GL and can receive the 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 the data wiring DL. In such a case, corresponding to the switching transistor ST being turned on, a data signal can be supplied through the switching transistor ST to the gate electrode of the driving transistor DT.

[0077] The first capacitor C1 can be disposed between the gate electrode and the second electrode of the driving transistor DT. 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.

[0078] 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.

[0079] 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 and 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.

[0080] The second selection transistor TP2 is disposed between the drive 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 a 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.

[0081] 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.

[0082] 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.

[0083] For example, the drive mode can include a first mode in which all of a plurality of regions of the display panel PN described with reference to FIG. 1 are controlled in a wide viewing angle mode (Share mode), and a second mode in which at least a part of the plurality of regions of the display panel PN, for example, the second region, is driven in a narrow viewing angle mode (Private mode).

[0084] 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 may be a source electrode or a drain electrode. For example, the first electrode may be a source electrode and the second electrode may be a drain electrode. As another example, the first electrode may be a drain electrode and the second electrode may be a source electrode.

[0085] 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.

[0086] On the other hand, FIG. 4 can show an exemplary pixel circuit SPC_1 applicable to the pixel circuit SPC shown in FIG. 3.

[0087] 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 a voltage for turning on the TFT, and the high level voltage of each drive signal may mean a voltage for turning off the TFT.

[0088] 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 a voltage corresponding to a voltage 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 a voltage corresponding to a voltage within the range of 12V to 16V. Depending on the 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.

[0089] Hereinafter, the first electrode or the second electrode of the transistor described below may mean a source electrode or a 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.

[0090] The pixel circuit SPC_1 can include a driving circuit DC_1, a selection circuit SC_1, and a plurality of light-emitting elements EDa, EDb.

[0091] The driving circuit DC_1 can include a driving transistor DT, a plurality of switching transistors ST1 to ST5, and a second capacitor C2.

[0092] The driving transistor DT can control the driving current applied to the plurality of light-emitting elements EDa, 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, a gate electrode connected to a second node N2, and a drain electrode connected to a third node N3.

[0093] 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 the 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.

[0094] 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 at a low level which is the turn-on level.

[0095] 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 low level which is the turn-on level.

[0096] The fourth switching transistor ST4 can apply a 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.

[0097] 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 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 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 turn-on level, which is a low level.

[0098] 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 maintain 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.

[0099] The selection circuit SC_1 can include a first selection transistor TP1 for generating a current path of a first drive current via the first type of light-emitting element EDa, and a second selection transistor TP2 for generating a current path of a second drive current via the second type of light-emitting element EDb.

[0100] The first selection transistor TP1 is disposed between the driving 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 a first selection signal wiring that provides a first selection signal Ss. When the pixel circuit SPC_1 is driven in the first state or the third state, if the first selection signal Ss is supplied to the gate electrode of the first selection transistor TP1, the first selection transistor TP1 is turned on, and a current path of the first drive current via 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.

[0101] The second selection transistor TP2 is disposed between the driving 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 a second selection signal wiring that provides a second selection signal Ps. When the pixel circuit SPC_1 is driven in the second state or the third state, if the second selection signal Ps is supplied to the gate electrode of the second selection transistor TP2, the second selection transistor TP2 is turned on, and a current path of the second drive current via 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.

[0102] The light-emitting element EDa of the first type 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 light-emitting element EDb of the second type can be connected between a second selection transistor TP2 that is turned on or off by a second selection signal Ps and the second power supply wiring that provides the second power supply voltage VSS, for example, the low-potential power supply voltage.

[0103] In such a case, the light-emitting element EDa of the first type or the light-emitting element EDb of the second type 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 a pre-specified condition is satisfied.

[0104] Figures 5a and 5b are waveform diagrams for explaining the pixel circuit of FIG. 4.

[0105] 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.

[0106] Referring to FIGS. 4 to 5b, when the pixel circuit SPC_1 is driven in the first state, only the light-emitting element EDa of the first type emits light, and when the pixel circuit SPC_1 is driven in the second state, only the light-emitting element EDb of the second type can emit light. Here, as shown in FIG. 5a, a second selection signal Ps for controlling the light emission of the light-emitting element EDb of the second type so that only the light-emitting element EDa of the first type emits light in the first state, 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. Also, as shown in FIG. 5b, in the second state, a first selection signal Ss for controlling the light emission of the light-emitting element EDa of the first type so that only the light-emitting element EDb of the second type emits light, 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.

[0107] Specifically, first, referring to FIGS. 4 and 5a, when considering the case where the pixel circuit SPC_1 operates in the first state, a low-level second scan signal SCAN2, a low-level first selection signal Ss, and a low-level light emission signal EM can be output during the initialization period. The low-level second scan signal SCAN2 turns on the second switching transistor ST2, the fourth switching transistor ST4, and the fifth switching transistor ST5, the low-level first selection signal Ss turns on the first selection transistor TP1, and the low-level light emission signal EM can turn on the third switching transistor ST3.

[0108] The first node N1 can be initialized to a 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 by shorting the gate electrode and the drain electrode of the driving transistor DT, the driving transistor DT can operate like a diode. And 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.

[0109] 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 light-emitting signal EM is output and the third switching transistor ST3 is turned off, at the same time, 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 the voltage difference between the first power supply voltage VDD and the threshold voltage can be sampled and supplied to the second node N2.

[0110] 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., sampling period) can be maintained by the second capacitor C2.

[0111] Finally, during the light-emitting period, a low-level first selection signal Ss and a light-emitting signal EM are output, 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 light-emitting signal EM, and the voltage of the first node N1 can become the voltage difference between the reference voltage Vref and the data signal (data voltage), and such voltage fluctuations 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 driving current can be controlled.

[0112] 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, a 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.

[0113] Next, referring to FIGS. 4 and 5b, when considering the operation of the pixel circuit SPC_1 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 the first state. That is, the first selection signal Ss is output only at a high level which is the turn-off level, and the second selection signal Ps can be output at a low level which is the turn-on level during the light emission period when the second type of light emitting element EDb emits light.

[0114] 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 emission signal EM can be output at a low level. Thus, the second switching transistor ST2, the fourth switching transistor ST4, and the fifth switching transistor ST5 are turned on by the second scan signal SCAN2, the second selection transistor TP2 is turned on by the second selection signal Ps, and the third switching transistor ST3 can be turned on by the light emission signal EM.

[0115] The first node N1 is initialized to the reference voltage Vref through the third switching transistor ST3 turned on by the light emission signal EM, and the anode electrodes of the first type of light emitting element EDa and the second type of 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 of 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.

[0116] 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 a low level to a 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 can be 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 voltage difference between the first power supply voltage VDD and the threshold voltage can be sampled and supplied to the second node N2.

[0117] Finally, a low-level second selection signal Ps and an emission signal EM are output during the emission period, and a high-level first selection signal Ss 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 the voltage difference 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 second driving current can be controlled.

[0118] Then, the 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.

[0119] On the other hand, although not shown in FIGS. 5A and 5B, when the pixel circuit SPC_1 is driven in the third state, since all of the first type of light-emitting element EDa and the second type of light-emitting element EDb emit light, 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, as described with reference to FIG. 5A, are substantially the same or similar, and the waveform of the second selection signal Ps in the third state and the operation of the pixel circuit SPC_1 in which the second driving current is formed thereby, and the waveform of the second selection signal Ps in the second state and the operation of the pixel circuit SPC_1 in which the second driving current is formed thereby, as described with reference to FIG. 5B, are substantially the same or similar, so the repeated description will not be repeated.

[0120] FIGS. 6 and 7 are cross-sectional views of a display device according to an embodiment of the present specification.

[0121] FIG. 6 shows a pixel in which the first type of lens 161 is arranged, and FIG. 7 shows a pixel in which the second type of lens 162 is arranged.

[0122] Referring to FIGS. 6 and 7, the display device 100 according to the 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.

[0123] 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.

[0124] A buffer film 111 can be disposed on the substrate 110. The buffer film 111 can contain an insulating material. For example, the buffer film 111 can contain an inorganic insulating material such as silicon oxide (SiOx) and silicon nitride (SiNx). The buffer film 111 can have a multilayer structure. For example, the buffer film 111 can have a laminated structure of a film made of silicon nitride (SiNx) and a film made of silicon oxide (SiOx).

[0125] The buffer film 111 can 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 during the formation process of the driving part. For example, the upper surface of the substrate 110 facing the driving part of each pixel PX can be covered by the buffer film 111. The driving part of each pixel PX can be located on the buffer film 111.

[0126] 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.

[0127] The gate insulating film 112 can extend between the semiconductor layers 121, 221 and the gate electrodes 122, 223 of the selection transistors TP1, TP2. For example, the gate electrodes of the driving transistor DT and the switching transistor ST 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.

[0128] 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 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 electrodes of the driving transistor DT and the switching transistor ST. The source electrodes and the drain electrodes 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 regions and the drain regions of the semiconductor patterns located within each pixel PX.

[0129] A lower protective film 114 can be disposed on the interlayer insulating film 113. 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 contact the interlayer insulating film 113 outside the driving portion located within each pixel PX.

[0130] An overcoat layer 115 can be disposed on the lower protective film 114. 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 formed by the driving portion of each pixel PX. For example, the upper surface of the overcoat layer 115 facing the substrate 110 can be a flat surface.

[0131] On the substrate 110, a first selection transistor TP1 and a second selection transistor TP2 may be disposed. The first selection transistor TP1 may 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 may 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.

[0132] The first selection transistor TP1 may include a first semiconductor layer 121, a first gate electrode 122, a first source electrode 123, and a first drain electrode 124. The first selection transistor TP1 may have the same structure as the switching transistor ST and the driving transistor DT. For example, the first semiconductor layer 121 may be located between the buffer film 111 and the gate insulating film 112, and the first gate electrode 122 may be located between the gate insulating film 112 and the interlayer insulating film 113. The first source electrode 123 and the first drain electrode 124 may be located between the interlayer insulating film 113 and the lower protective film 114. The first gate electrode 122 may overlap the channel region of the first semiconductor layer 121. The first source electrode 123 may be electrically connected to the source region of the first semiconductor layer 121. The first drain electrode 124 may be electrically connected to the drain region of the first semiconductor layer 121.

[0133] The second selection transistor TP2 may include a second semiconductor layer 221, a second gate electrode 223, a second source electrode 225, and a second drain electrode 227. For example, the second semiconductor layer 221 may be located in the same layer as the first semiconductor layer 121, the second gate electrode 223 may be located in the same layer as the first gate electrode 122, and the second source electrode 225 and the second drain electrode 227 may be located in the same layer as the first source electrode 123 and the first drain electrode 124.

[0134] The first type of light-emitting element EDa and the second type of light-emitting element EDb of each pixel PX may be disposed on the overcoat layer 115 of the corresponding pixel PX.

[0135] The first type of light-emitting element EDa can emit light showing 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 sequentially stacked on a substrate 110.

[0136] The first lower electrode 141 can contain a conductive material. The first lower electrode 141 can contain a material having a high reflectivity. For example, the first lower electrode 141 can contain metals such as aluminum (Al) and silver (Ag). The first lower electrode 141 can have a multilayer structure. For example, the first lower electrode 141 can have a structure in which a reflective electrode made of a metal is positioned between transparent electrodes made of transparent conductive materials such as ITO and IZO. The first lower electrode 141 can be electrically connected to the first drain electrode 124 of the first selection transistor TP1 through a contact hole penetrating the lower protective film 114 and the overcoat layer 115.

[0137] The first light-emitting layer 142 can generate light with a luminance corresponding to the voltage difference between the first lower electrode 141 and the first upper electrode 143. For example, the first light-emitting layer 142 can include a light-emitting material layer (EML) containing a light-emitting material. The light-emitting material can include an organic material, an inorganic material, or a hybrid material.

[0138] The first light-emitting layer 142 can have a multilayer structure. For example, the first light-emitting layer 142 can further include at least one of a hole injection layer (HIL), a hole transport layer (HTL), an electron transport layer (ETL), and an electron injection layer (EIL).

[0139] The first upper electrode 143 can include a conductive material. The first upper electrode 143 can include a material different from that of the first lower electrode 141. The transmittance of the first upper electrode 143 may be higher than that of the first lower electrode 141. For example, the first upper electrode 143 may be a transparent electrode made of a transparent conductive material such as ITO and IZO. Accordingly, in the display device 100 according to the embodiments of the present specification, the light generated by the first light-emitting layer 142 can be emitted through the first upper electrode 143.

[0140] 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 can include a second lower electrode 151, a second light-emitting layer 152, and a second upper electrode 153 sequentially stacked on a substrate 110.

[0141] 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.

[0142] The second light-emitting layer 152 may be separated from the first light-emitting layer 142. Accordingly, in the display device according to the embodiments of the present specification, light emission due to leakage current can be prevented.

[0143] The second lower electrode 151 of each pixel PX can be separated from the first lower electrode 141 of the corresponding pixel PX. For example, a bank insulating film 116 can be disposed between the first lower electrode 141 and the second lower electrode 151 of each pixel PX. The bank insulating film 116 can contain an insulating material. For example, the bank insulating film 116 can contain an organic insulating material. The bank insulating film 116 can contain a material different from that of the overcoat layer 115.

[0144] 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. Accordingly, in the display device 100, an image by the first lens region of each pixel PX where the first type of light-emitting element EDa is located or an image by the second lens region of each pixel PX where the second type of light-emitting element EDb is located can be provided to the user.

[0145] 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 a first light-emitting region where light is emitted by the first type of light-emitting element EDa and a second light-emitting region where light is emitted by the second type of light-emitting element EDb within each pixel PX. The size of the second light-emitting region divided within each pixel PX can be smaller than the size of the first light-emitting region.

[0146] 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 within 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 within the corresponding pixel PX. The second upper electrode 153 of each pixel PX can contain 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 lens region and the luminance of the second lens region located within each pixel PX can be controlled by the drive current generated in the corresponding pixel PX.

[0147] A sealing member 180 can be positioned 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, 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, but is not limited to, a first sealing layer 181, a second sealing layer 182, and a third sealing layer 183 laminated in sequence. The first sealing layer 181, the second sealing layer 182, and the third sealing layer 183 can contain an insulating material. The second sealing layer 182 can contain a material different from that of 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 containing an inorganic insulating material, and the second sealing layer 182 can include an organic sealing layer containing an organic insulating material. Thereby, damage to the light-emitting elements EDa, EDb of the display device 100 due to moisture and impact from the outside can be more effectively prevented.

[0148] The first type of lens 161 and the second type of lens 162 can be arranged on the sealing member 180.

[0149] 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 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.

[0150] In such a case, the traveling direction of the light emitted in the first lens region of each pixel PX does not need to be restricted in one direction. For example, the content (or image) provided through the first lens region of each pixel PX can be shared with people in the surroundings adjacent to the user in one direction. As a result, 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 mode (Share mode).

[0151] 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.

[0152] In such a case, the traveling direction of the light emitted in the second lens region of each pixel PX can be restricted to one direction and / or another direction. For example, the content (or image) provided by the second lens region of each pixel PX does not have to be shared with 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.

[0153] The first light-emitting region 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 light-emitting region 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 light-emitting region of the corresponding pixel PX. Accordingly, the efficiency of the light emitted from the first light-emitting region of the pixel PX can be improved.

[0154] The second light-emitting region 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 light-emitting region 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 light-emitting region of the corresponding pixel PX. Accordingly, the efficiency of the light emitted from the second light-emitting region of the pixel PX can be improved.

[0155] On the first type of lens 161 and the second type of lens 162 of the pixel PX, a lens protective film 170 may be located. The lens protective film 170 can include an insulating substance. For example, the lens protective film 170 can include an organic insulating substance. The refractive index of the lens protective film 170 may be smaller than the refractive index of the first type of lens 161 and the refractive index of 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 that has passed through the first type of lens 161 and the second type of lens 162 of each pixel PX does not have to be reflected in the direction of the substrate 110 due to the refractive index difference with the lens protective film 170.

[0156] Referring to FIGS. 6 and 7, as described above, the pixel PX can include 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, but is not limited thereto.

[0157] For example, the pixel PX can also include a plurality of first type of lenses 161 disposed above the first type of light-emitting element EDa and above the second type of light-emitting element EDb, respectively. A detailed description thereof will be given later with reference to FIG. 8.

[0158] FIG. 8 is a circuit diagram showing an example of a first pixel of a display device according to an embodiment of the present specification. FIG. 9 is a circuit diagram showing an example of a second pixel of a display device according to an embodiment of the present specification. FIG. 10 is a circuit diagram showing an example of a third pixel of a display device according to an embodiment of the present specification.

[0159] On the other hand, in FIGS. 8 to 10, examples of the first pixel PX1, the second pixel PX2, and the third pixel PX3 included in the plurality of pixels PX disposed on the display panel PN of the display device 100 according to an embodiment of the present specification described with reference to FIG. 2 are shown, respectively.

[0160] On the one hand, each of the first pixel PX1, the second pixel PX2, and the third pixel PX3 shown in FIGS. 8 to 10 can include the pixel circuit SPC described with reference to FIG. 3 or the pixel circuit SPC_1 described with reference to FIG. 4. Accordingly, descriptions overlapping with those described with reference to FIGS. 3 and 4 will not be repeated.

[0161] Also, for convenience of explanation, in FIGS. 8 to 10, only the selection circuit, the plurality of light-emitting elements, and the plurality of lenses among the configurations included in the first pixel PX1, the second pixel PX2, and the third pixel PX3 are shown. Here, for convenience of explanation, only the corresponding relationship of the plurality of lenses is schematically shown by dotted lines.

[0162] First, referring to FIGS. 3, 4, and 8, the first pixel PX1 can include a first selection circuit SC1 and a plurality of light-emitting elements ED1 and ED2.

[0163] 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. 8 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.

[0164] 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.

[0165] 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 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, a second power supply wiring that provides 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 that provides the second power supply voltage VSS. For example, the first light-emitting element ED1 and the second light-emitting element ED2 in FIG. 8 can 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.

[0166] Accordingly, when the first transistor T1 is turned on in response to the 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.

[0167] Also, 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.

[0168] The first pixel PX1 can be driven in a first state where the first light-emitting element ED1 emits light, or in a third state where both the first light-emitting element ED1 and the second light-emitting element ED2 emit light.

[0169] The first pixel PX1 can 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. For example, the first lens LS1 and the second lens LS2 can be embodied as the first type of lens 161 described with reference to FIG. 6, respectively.

[0170] 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.

[0171] 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.

[0172] 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 a first viewing angle.

[0173] Here, as described above, the first pixel PX1 can be driven in a first state in which the first light-emitting element ED1 emits light, or 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 first state, the content is provided at a first viewing angle by the light generated by the first light-emitting element ED1, and when the first pixel PX1 is driven in the third state, the content can be provided at a 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.

[0174] On the one hand, when the first pixel PX1 is driven in the third state as compared with the first state in which only the first light-emitting element ED1 emits light, the content is provided at the first viewing angle in the same manner as in the first state. However, since both the first light-emitting element ED1 and the second light-emitting element ED2 emit light, the luminance of the corresponding content can increase. That is, based on the same data signal being written, the luminance when the first pixel PX1 is driven in the third state may be higher than the luminance when it is driven in the first state.

[0175] Next, referring to FIGS. 3, 4, and 9, the second pixel PX2 can include a second selection circuit SC2 and a plurality of light-emitting elements ED3, ED4.

[0176] The second selection circuit SC2 can include a third transistor T3 and a fourth transistor T4. The third transistor T3 and the fourth transistor T4 in FIG. 9 can 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 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.

[0178] The plurality of light-emitting elements ED3 and ED4 included in the second pixel PX2 can include the third light-emitting element ED3 and the 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 the second power supply wiring that provides the second power supply voltage VSS, and the fourth light-emitting element ED4 of the second pixel PX2 can be connected between the fourth transistor T4 and the second power 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. 9 can 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 third transistor T3 is turned on in response to the turn-on level selection signal provided from the third selection signal wiring SSL3, a first drive 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.

[0180] Also, when the fourth transistor T4 is turned on in response to the turn-on level selection signal provided from the fourth selection signal wiring SSL4, a second drive 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.

[0181] The second pixel PX2 can be driven in a first state in which the third light-emitting element ED3 emits light, or in a third state in which both the third light-emitting element ED3 and the fourth light-emitting element ED4 emit light.

[0182] The second pixel PX2 can 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. For example, the third lens LS3 can be embodied as the first type of lens 161 described with reference to FIG. 6, and the fourth lens LS4 can be embodied as the second type of lens 162 described with reference to FIG. 7.

[0183] Accordingly, when a first driving current is formed within 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. Therefore, the content provided by the light generated by the third light-emitting element ED3 of the second pixel PX2 can be provided at the first viewing angle.

[0184] Also, when a second driving current is formed within 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. Therefore, the content provided by the light generated by the fourth light-emitting element ED4 of the second pixel PX2 can be provided at the second viewing angle.

[0185] 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 third state in which both the third light-emitting element ED3 and the fourth light-emitting element ED4 emit light. Accordingly, when the second pixel PX2 is driven in the first state, the content can be provided at the first viewing angle by the light generated by the third light-emitting element ED3. Also, when the second pixel PX2 is driven in the third state, the content is provided at the first viewing angle by the light generated by the third light-emitting element ED3, and the content can be provided at the second viewing angle by the light generated by the fourth light-emitting element ED4. Here, even when the content is provided at the second viewing angle, the content at the first viewing angle is also provided. Therefore, ultimately, the content at the first viewing angle can be provided to the user. Accordingly, the content at the first viewing angle can be provided to the user whether the second pixel PX2 is driven in the first state or the third state.

[0186] On one hand, when the second pixel PX2 is driven in the third state as compared to the first state where only the third light-emitting element ED3 emits light, the content is provided at the first viewing angle in the same manner as in the first state. However, since both the third light-emitting element ED3 and the fourth light-emitting element ED4 emit light, the luminance of the corresponding content can increase. That is, based on the same data signal being written, the luminance when the second pixel PX2 is driven in the third state may be higher than the luminance when it is driven in the first state.

[0187] Next, referring to FIGS. 3, 4, and 10, the third pixel PX3 can include a third selection circuit SC3 and a plurality of light-emitting elements ED5, ED6.

[0188] The third selection circuit SC3 can include a fifth transistor T5 and a sixth transistor T6. The fifth transistor T5 and the sixth transistor T6 in FIG. 10 can be transistors corresponding to the first selection transistor TP1 and the second selection transistor TP2 described with reference to FIGS. 3 and 4, respectively.

[0189] The gate electrode of the fifth transistor T5 can be turned on or off in response to a selection signal provided from the fifth selection signal wiring SSL5, and the gate electrode of the sixth transistor T6 can be turned on or off in response to a selection signal provided from the sixth selection signal wiring SSL6. Here, the selection signal provided from the fifth selection signal wiring SSL5 and the selection signal provided from the sixth selection signal wiring SSL6 can 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.

[0190] The plurality of light-emitting elements ED5 and ED6 included in the third pixel PX3 can include a fifth light-emitting element ED5 and a sixth light-emitting element ED6. Substantially the same or similar to that described with reference to FIGS. 3 and 4, the fifth light-emitting element ED5 of the third pixel PX3 is connected between the fifth transistor T5 and a second power supply wiring that provides a second power supply voltage VSS, and the sixth light-emitting element ED6 of the third pixel PX3 can be connected between the sixth transistor T6 and the second power supply wiring that provides the second power supply voltage VSS. For example, the fifth light-emitting element ED5 and the sixth light-emitting element ED6 in FIG. 10 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.

[0191] Accordingly, when the fifth transistor T5 is turned on in response to a turn-on level selection signal provided from the fifth selection signal wiring SSL5, a first drive current passing through the fifth light-emitting element ED5 is formed, and the fifth light-emitting element ED5 of the third pixel PX3 can emit light.

[0192] Also, when the sixth transistor T6 is turned on in response to a turn-on level selection signal provided from the sixth selection signal wiring SSL6, a second drive current passing through the sixth light-emitting element ED6 is formed, and the sixth light-emitting element ED6 of the third pixel PX3 can emit light.

[0193] The third pixel PX3 can be driven in a first state in which the fifth light-emitting element ED5 emits light or in a second state in which the sixth light-emitting element ED6 emits light.

[0194] The third pixel PX3 can include a fifth lens LS5 disposed above the fifth light-emitting element ED5 and a sixth lens LS6 disposed above the sixth light-emitting element ED6. For example, the fifth lens LS5 can be embodied as the first type of lens 161 described with reference to FIG. 6, and the sixth lens LS6 can be embodied as the second type of lens 162 described with reference to FIG. 7.

[0195] That is, the third pixel PX3 may have a lens structure substantially the same as that of the second pixel PX2, for example, a lens structure including a first type of lens 161 disposed above the fifth light-emitting element ED5 and a second type of lens 162 disposed above the sixth light-emitting element ED6.

[0196] Accordingly, when a first driving current is formed in the third pixel PX3 and the fifth light-emitting element ED5 emits light, the light generated by the fifth light-emitting element ED5 of the third pixel PX3 is emitted through the fifth lens LS5 embodied in the first type of lens 161. Therefore, the content provided by the light generated by the fifth light-emitting element ED5 of the third pixel PX3 can be provided at the first viewing angle.

[0197] Also, when a second driving current is formed in the third pixel PX3 and the sixth light-emitting element ED6 emits light, the light generated by the sixth light-emitting element ED6 of the third pixel PX3 is emitted through the sixth lens LS6 embodied in the second type of lens 162. Therefore, the content provided by the light generated by the sixth light-emitting element ED6 of the third pixel PX3 can be provided at the second viewing angle.

[0198] Here, as described above, the third pixel PX3 can be driven in a first state in which the fifth light-emitting element ED5 emits light or in a second state in which the sixth light-emitting element ED6 emits light. Accordingly, when the third pixel PX3 is driven in the first state, the content can be provided at the first viewing angle by the light generated by the fifth light-emitting element ED5. Also, when the third pixel PX3 is driven in the second state, the content can be provided at the second viewing angle by the light generated by the sixth light-emitting element ED6.

[0199] In this way, even if the second pixel PX2 and the third pixel PX3 have the same lens structure, the second pixel PX2 and the third pixel PX3 can provide content in different driving modes according to the selection signals provided from the third and fourth selection signal wirings SSL3 and SSL4 of the second pixel PX2 and the fifth and sixth selection signal wirings SSL5 and SSL6 of the third pixel PX3. For example, as described above, since the second pixel PX2 is driven in the first state or the third state, it provides only the content in the wide viewing angle mode, and since the third pixel PX3 is driven in the first state or the second state, it can provide the content in the wide viewing angle mode or the content in the narrow viewing angle mode.

[0200] FIG. 11 is a diagram showing an example of a display panel of a display device according to an embodiment of the present specification. FIG. 12 is a diagram showing an example of a first region of the display panel of FIG. 11.

[0201] On the other hand, in FIG. 11, 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. 12, an example of the first region A1 included in the display panel PN of FIG. 11 is shown.

[0202] On the other hand, for convenience of explanation, in FIGS. 11 and 12, 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.

[0203] Referring to FIGS. 2 and 11, the display panel PN can be partitioned into a plurality of regions A1 and A2. For example, as shown in FIG. 11, the display panel PN can be partitioned into two regions A1 and 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.

[0204] Each of the regions A1 and 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 and a plurality of second pixels PX2 are arranged at intervals along the first direction DR1 and the second direction DR2, and in the second region A2, a plurality of third pixels PX3 can be arranged at intervals along the first direction DR1 and the second direction DR2.

[0205] To more specifically describe the arrangement of the plurality of first pixels PX1 and the plurality of second pixels PX2 arranged in the first region A1, referring further to FIG. 12, the first region A1 of the display panel PN can include first to third sub-regions AA1 to AA3 sequentially arranged along the first direction DR1. For example, the second sub-region AA2 can be arranged adjacent to the first sub-region AA1 along the first direction DR1, and the third sub-region AA3 can be arranged adjacent to the second sub-region AA2 along the first direction DR1.

[0206] Referring to FIGS. 11 and 12, the first and second sub-regions AA1 and AA2 of the first region A1 are defined as a part of the first region A1 adjacent to the second region A2, and the third sub-region AA3 can be defined as the remaining region of the first region A1 excluding the first and second sub-regions AA1 and AA2. Here, the first and second sub-regions AA1 and AA2, which are a part of the first region A1 adjacent to the second region A2 shown in FIG. 12, are exemplary, and a part of the first region A1 adjacent to the second region A2 can be variously set according to the design of the display panel PN.

[0207] Each of the first to third sub-regions AA1 to AA3 can include a plurality of pixels arranged at intervals along the first direction DR1 and the second direction DR2, for example, the first pixel PX1 and / or the second pixel PX2.

[0208] The first to third sub-regions AA1 to AA3 can have different densities (or pixel densities) with respect to the second pixel PX2. That is, the second pixel PX2 can be arranged at different densities (or pixel densities) in the first to third sub-regions AA1 to AA3.

[0209] In the first region A1, as going in the first direction DR1, the ratio of the area where the second pixels PX2 are arranged per unit area, for example, the pixel density, may decrease. For example, as going from the first sub-region AA1 to the third sub-region AA3, that is, as getting farther from the boundary between the first region A1 and the second region A2 within the first region A1, the ratio of the area where the second pixels PX2 are arranged per unit area may decrease.

[0210] For example, on the first sub-region AA1, a plurality of first pixels PX1 and a plurality of second pixels PX2 are arranged, and the plurality of second pixels PX2 may be arranged at the first pixel density in the first sub-region AA1.

[0211] Also, on the second sub-region AA2, a plurality of first pixels PX1 and a plurality of second pixels PX2 are arranged, and the plurality of second pixels PX2 may be arranged at a second pixel density lower than the first pixel density of the first sub-region AA1 in the second sub-region AA2.

[0212] Also, only a plurality of first pixels PX1 may be arranged on the third sub-region AA3. In other words, no second pixel PX2 is arranged on the third sub-region AA3, the third pixel density of the third sub-region AA3 is lower than the second pixel density of the second sub-region AA2, and the third pixel density where the second pixel PX2 is arranged on the third sub-region AA3 may be defined as 0.

[0213] Here, the density or pixel density is defined as the ratio (%) of the area where the corresponding pixels are arranged to the total area of the corresponding region, or may be defined as the ratio (%) of the area where the corresponding pixels are arranged to a preset unit area. The area where the corresponding pixels are arranged may be the sum of the areas of each pixel, but is not limited thereto.

[0214] On one hand, the area of a pixel may mean the area of a region including a pixel circuit and a light-emitting element. As another example, the area of a pixel may mean the area of a light-emitting surface of a light-emitting element. For example, when a pixel includes an organic light-emitting diode, the area of the pixel may be the area of an anode electrode exposed between pixel defining films, or the area of a light-emitting layer.

[0215] Alternatively, the density or pixel density may be defined as the total number of corresponding pixels (pixels per inch, PPI) with respect to the total area of the corresponding region, or may be defined as the total number of corresponding pixels (pixels per inch, PPI) with respect to a preset unit area.

[0216] More specifically, referring to FIG. 12, the first sub-region AA1 of the first region A1 may include a plurality of first pixels PX1 sequentially arranged along the second direction DR2 on the first column C1, and a plurality of second pixels PX2 sequentially arranged along the second direction DR2 on the second column C2 adjacent to the first column C1 in the first direction DR1. In this way, when a plurality of second pixels PX2 are arranged on the second column C2, which is one of the two columns C1 and C2, and a plurality of first pixels PX1 are arranged on the first column C1, which is the remaining one of the two columns, it can be defined that the plurality of second pixels PX2 are arranged at the first pixel density on the first sub-region AA1.

[0217] Further, the second sub-region AA2 of the first region A1 includes a plurality of first pixels PX1 sequentially arranged along the second direction DR2 on the third column C3 adjacent to the second column C2 in the first direction DR1 and the fourth column C4 adjacent to the third column C3 in the first direction DR1, and a plurality of second pixels PX2 sequentially arranged along the second direction DR2 on the fifth column C5 adjacent to the fourth column C4 in the first direction DR1. In this way, when a plurality of second pixels PX2 are arranged on one of the three columns C3, C4, and C5, that is, the fifth column C5, and a plurality of first pixels PX1 are arranged on the remaining two columns, that is, the third column C3 and the fourth column C4, the plurality of second pixels PX2 on the second sub-region AA2 can be defined as being arranged with a second pixel density. Here, as described above, the second pixel density of the second sub-region AA2 may be lower than the first pixel density of the first sub-region AA1.

[0218] Also, only a plurality of first pixels PX1 can be arranged on a region excluding the first and second sub-regions AA1 and AA2 where the second pixels PX2 are arranged in the first region A1. For example, a plurality of first pixels PX1 can be sequentially arranged along the second direction DR2 on a plurality of columns on the third sub-region AA3, including the sixth column C6 adjacent to the fifth column C5 in the first direction DR1, the seventh column C7 adjacent to the sixth column C6 in the first direction DR1, the eighth column C8 adjacent to the seventh column C7 in the first direction DR1, the ninth column C9 adjacent to the eighth column C8 in the first direction DR1, the tenth column C10 adjacent to the ninth column C9 in the first direction DR1, the eleventh column C11 adjacent to the tenth column C10 in the first direction DR1, the twelfth column C12 adjacent to the eleventh column C11 in the first direction DR1, and the thirteenth column C13 adjacent to the twelfth column C12 in the first direction DR1. In this way, when only a plurality of first pixels PX1 are arranged on a plurality of columns, the second pixels PX2 on the third sub-region AA3 can be defined as being arranged with a third pixel density. For example, the third pixel density of the third sub-region AA3 is lower than the second pixel density of the second sub-region AA2. For example, the third pixel density may have a value substantially equal to 0.

[0219] 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 a wide viewing angle mode. 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 may be a region that provides content in a wide viewing angle mode or a narrow viewing angle mode depending on the driving mode of the display device 100.

[0220] For example, as described above, on the first region A1 of the display panel PN, the first pixel PX1 and the second pixel PX2 driven in the first state or the third state are arranged to provide content to the user at a first viewing angle. On the second region A2 of the display panel PN, the third pixel PX3 driven in the first state or the second state is arranged, and content can be provided to the user at the first viewing angle or the second viewing angle.

[0221] As in the display device 100 according to an embodiment of the present specification, not only the first pixel PX1 including only the first type of lens 161 on the first region A1 that provides content at the first viewing angle, but also the lens structure such as the third pixel PX3 arranged on the second region A2, that is, the second pixel PX2 including the first type of lens 161 and the second type of lens 162 are arranged together, so that the problem of the boundary between the first region A1 and the second region A2 being visible can be minimized.

[0222] More specifically, unlike the display device 100 according to an embodiment of the present specification, in the case of the comparative example of the present specification in which only the first pixel PX1 including only the first type of lens 161 is arranged on the first region A1 and no second pixel PX2 is arranged, and the third pixel PX3 including the first type of lens 161 and the second type of lens 162 is arranged on the second region A2, as described with reference to FIGS. 6 and 7, since the first type of lens 161 and the second type of lens 162 have different shapes from each other, the area of the first light-emitting region exposed by the first type of lens 161 and the area of the second light-emitting region exposed by the second type of lens 162 are different, and a problem may occur in which the boundary between the first region A1 and the second region A2 is visually recognized. For example, in a power-off state, even if the pixels arranged on the display panel do not display an image, the boundary between the first region A1 and the second region A2 may be visually recognized due to external light reflection. As another example, in a power-on state, when the pixels arranged on the display panel display an image in a narrow viewing angle mode, the boundary between the first region A1 and the second region A2 may be visually recognized due to the area difference of the light-emitting regions described above.

[0223] On the other hand, in the case of the display device 100 according to an embodiment of the present specification, the first region A1 of the display panel PN that provides content at the first viewing angle includes not only the first pixel PX1 but also the second pixel PX2 having a lens structure such as the third pixel PX3 arranged on the second region A2, so that the problem of visually recognizing the boundary between the first region A1 and the second region A2 can be minimized.

[0224] Hereinafter, with reference to FIGS. 13a to 15, an example in which the display panel PN is driven according to the driving mode of the display device 100 will be described in more detail.

[0225] FIG. 13a 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. 13b 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. FIG. 14 is a diagram for explaining an example in which the first region of FIG. 12 is driven. FIG. 15 is a diagram for explaining another example in which the first region of FIG. 12 is driven.

[0226] On the other hand, FIGS. 13a and 13b show examples of the second region A2 when the display device 100 according to an embodiment of the present specification is driven in the first mode and the second mode, respectively.

[0227] Referring to FIGS. 2 to 12, the mode controller MS included in the display device 100 can generate a mode selection signal MSS based on a mode signal input from the outside. For example, the mode controller MS can receive an input of a mode signal from the outside corresponding to the driving mode of the display device 100, generate a mode selection signal MSS based on the mode signal, 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, a plurality of second pixels PX2 arranged in the first region A1, and a plurality of third pixels PX3 arranged in the second region A2 in response to the mode selection signal MSS provided from the mode controller MS.

[0228] 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.

[0229] Specifically, referring further to FIG. 13a, in the first mode, each of the plurality of third pixels PX3 arranged on the second region A2 can be driven in a first state.

[0230] For example, in the first mode, in response to the selection signal provided through the fifth selection signal wiring SSL5, the fifth transistor T5 included in the third pixel PX3 is turned on, and a first driving current is formed within the third pixel PX3. The light generated by the fifth light-emitting element ED5 of the third pixel PX3 emitting light due to the first driving current is emitted through the fifth lens LS5 composed of the first type of lens 161, whereby content with a first viewing angle can be provided.

[0231] On the other hand, in the first mode, since the selection signal provided to the sixth selection signal wiring SSL6 is maintained at the turn-off level, the sixth transistor T6 included in the third pixel PX3 is maintained in the turn-off state, and the sixth light-emitting element ED6 of the third pixel PX3 can be maintained in the non-light-emitting state (state of not emitting light).

[0232] 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.

[0233] Specifically, referring further to FIG. 13b, in the second mode, each of the plurality of third pixels PX3 arranged on the second region A2 can be driven in the second state.

[0234] For example, in the second mode, in response to the selection signal provided through the sixth selection signal wiring SSL6, the sixth transistor T6 included in the third pixel PX3 is turned on, and a second driving current is formed within the third pixel PX3. The light generated by the sixth light-emitting element ED6 of the third pixel PX3 emitting light due to the second driving current is emitted through the sixth lens LS6 composed of the second type of lens 162, whereby content with a second viewing angle can be provided.

[0235] On the other hand, in the second mode, since the selection signal provided to the fifth selection signal wiring SSL5 is maintained at the turn-off level, the fifth transistor T5 included in the third pixel PX3 is maintained in the turn-off state, and the fifth light-emitting element ED5 of the third pixel PX3 can be maintained in the non-light-emitting state (state of not emitting light).

[0236] Thus, when the display device 100 is driven in the first mode, on the second region A2 of the display panel PN, content with a first viewing angle is provided to the user, and when the display device 100 is driven in the second mode, on the second region A2 of the display panel PN, content with a second viewing angle may be provided to the user.

[0237] Also, as described above, in either the first mode in which content in a wide viewing angle mode is provided or the second mode in which content in a narrow viewing angle mode is provided, the first region A1 of the display panel PN can be driven to provide content with a first viewing angle.

[0238] For example, in any case where the display device 100 is driven in the first mode or the second mode, in response to a selection signal provided from the mode selection unit MD, the first region A1 of the display panel PN can provide content with a first viewing angle to the user.

[0239] Specifically, referring further to FIG. 14, in each of the first mode and the second mode, each of the plurality of first pixels PX1 and the plurality of second pixels PX2 disposed on the first region A1, for example, the first to third sub-regions AA1 to AA3, can be driven in a first state.

[0240] For example, in each of the first mode and the second mode, in response to a selection signal provided through the first selection signal wiring SSL1, the first transistor T1 included in the first pixel PX1 is turned on, and a first drive current is formed within the first pixel PX1. In response to a selection signal provided through the third selection signal wiring SSL3, the third transistor T3 included in the second pixel PX2 may be turned on, and a first drive current may be formed within the second pixel PX2. Further, light generated by the first light emitting element ED1 of the first pixel PX1 emitting light due to the first drive current is emitted through the first lens LS1 composed of the first type of lens 161, and light generated by the third light emitting element ED3 of the second pixel PX2 emitting light due to the first drive current is emitted through the third lens LS3 composed of the first type of lens 161, whereby content with a first viewing angle may be provided.

[0241] On the other hand, in this case, since selection signals maintained at a turn-off level are provided to the second selection signal wiring SSL2 and the fourth selection signal wiring SSL4, respectively, the second transistor T2 included in the first pixel PX1 and the fourth transistor T4 included in the second pixel PX2 are each maintained in a turn-off state, and the second light emitting element ED2 of the first pixel PX1 and the fourth light emitting element ED4 of the second pixel PX2 may each be maintained in a non-light emitting state (a state where they do not emit light).

[0242] However, the driving method of the first region A1 for providing content in a wide viewing angle mode in each of the first mode and the second mode is not limited to this.

[0243] For example, referring further to FIG. 15, as described above, in each of the first mode and the second mode, each of the plurality of first pixels PX1 and the plurality of second pixels PX2 disposed on the first region A1, for example, the first to third sub-regions AA1 to AA3, may be driven in a third state.

[0244] For example, in each of the first mode and the second mode, in response to a 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 drive current in the first pixel PX1, and in response to a selection signal provided through the third selection signal wiring SSL3, the third transistor T3 included in the second pixel PX2 is turned on to form a first drive current in the second pixel PX2. Also, the light generated by the first light-emitting element ED1 of the first pixel PX1 emitting light due to the first drive current is emitted through the first lens LS1 composed of the first type of lens 161, and the light generated by the third light-emitting element ED3 of the second pixel PX2 emitting light due to the first drive current is emitted through the third lens LS3 composed of the first type of lens 161, whereby content with a first viewing angle can be provided.

[0245] Also, in each of the first mode and the second mode, in response to a 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 drive current in the first pixel PX1, and in response to a selection signal provided through the fourth selection signal wiring SSL4, the fourth transistor T4 included in the second pixel PX2 is turned on to form a second drive current in the second pixel PX2. Also, the light generated by the second light-emitting element ED2 of the first pixel PX1 emitting light due to the second drive current is emitted through the second lens LS2 composed of the first type of lens 161, and the light generated by the fourth light-emitting element ED4 of the second pixel PX2 emitting light due to the second drive current is emitted through the fourth lens LS4 composed of the second type of lens 162, whereby content with a second viewing angle can be provided.

[0246] That is, in the embodiment of FIG. 15, in each of the first mode and the second mode, the first pixel PX1 is driven in the third state so that all of the first light-emitting element ED1 and the second light-emitting element ED2 emit light, and the second pixel PX2 is driven in the third state so that all of the third light-emitting element ED3 and the fourth light-emitting element ED4 can emit light. Here, as described above, the content is 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 of the first pixel PX1, respectively, and the content in the wide viewing angle mode can be provided to the user from the first pixel PX1. Also, the content is provided at the first viewing angle by the light generated by the third light-emitting element ED3 of the second pixel PX2, and the content can be provided at the second viewing angle by the light generated by the fourth light-emitting element ED4. Here, since the content at the first viewing angle is also provided even when the content is provided at the second viewing angle, finally, the content in the wide viewing angle mode can be provided to the user from the second pixel PX2.

[0247] In such an embodiment of FIG. 15, similar to the embodiment of FIG. 14, the display device 100 can display the content at the first viewing angle on the first region A1 of the display panel PN in each of the first mode and the second mode. Compared with the embodiment of FIG. 14, since the light-emitting elements ED1 and ED2 of the first pixel PX1 and the light-emitting elements ED3 and ED4 of the second pixel PX2 emit light, the luminance of the corresponding content can be increased. That is, based on the case where the same data signal is written, the luminance when the first pixel PX1 and the second pixel PX2 are driven in the third state as in the embodiment of FIG. 15 may be higher than the luminance when driven in the first state. Thereby, the power consumption for luminance increase can be improved.

[0248] FIG. 16 is a diagram showing another example of the first region of the display panel of FIG. 11.

[0249] FIG. 16 shows a modified embodiment with respect to the embodiment of FIG. 12 in relation to the pixel density of the second pixel PX2 arranged on the first region A1_1. Accordingly, in FIG. 16, in order to avoid redundant description, the description will be centered on the points different from the above-described embodiments.

[0250] In FIG. 16, an example of the first region A1_1 included in the display panel PN of FIG. 11 is shown.

[0251] Referring to FIG. 16, the first region A1_1 of the display panel PN can include first to third sub-regions AA1_1, AA2_1, and AA3_1 that are sequentially arranged along the first direction DR1. For example, the second sub-region AA2_1 can be arranged adjacent to the first sub-region AA1_1 along the first direction DR1, and the third sub-region AA3_1 can be arranged adjacent to the second sub-region AA2_1 along the first direction DR1.

[0252] Referring to FIGS. 11 and 16, the first and second sub-regions AA1_1 and AA2_1 of the first region A1_1 are defined as a part of the first region A1_1 that is adjacent to the second region A2, and the third sub-region AA3_1 can be defined as the remaining region of the first region A1_1 excluding the first and second sub-regions AA1_1 and AA2_1. Here, the first and second sub-regions AA1_1 and AA2_1, which are a part of the first region A1_1 adjacent to the second region A2 shown in FIG. 16, are exemplary, and a part of the first region A1_1 adjacent to the second region A2 can be variously set according to the design of the display panel PN.

[0253] Each of the first to third sub-regions AA1_1 to AA3_1 can include a plurality of pixels that are spaced apart from each other along the first direction DR1 and the second direction DR2.

[0254] The first to third sub-regions can have different densities with respect to the second pixel PX2. That is, the second pixel PX2 can be arranged at different densities in the first to third sub-regions AA1_1 to AA3_1.

[0255] In the first region A1_1, as going in the first direction DR1, the ratio of the area where the second pixels PX2 are arranged per unit area may decrease. For example, as going from the first sub-region AA1_1 to the third sub-region AA3_1, that is, as getting farther from the boundary between the first region A1_1 and the second region A2 within the first region A1_1, the ratio of the area where the second pixels PX2 are arranged per unit area may decrease.

[0256] For example, on the first sub-region AA1_1, a plurality of first pixels PX1 and a plurality of second pixels PX2 may be arranged, and the plurality of second pixels PX2 may be arranged at the first pixel density in the first sub-region AA1_1.

[0257] Also, on the second sub-region AA2_1, a plurality of first pixels PX1 and a plurality of second pixels PX2 may be arranged, and the plurality of second pixels PX2 may be arranged at a second pixel density lower than the first pixel density of the first sub-region AA1_1 in the second sub-region AA2_1.

[0258] Also, only a plurality of first pixels PX1 may be arranged on the third sub-region AA3_1. In other words, no second pixel PX2 is arranged on the third sub-region AA3_1, and the third pixel density at which the second pixel PX2 is arranged on the third sub-region AA3_1 may be defined as 0.

[0259] More specifically, referring to FIG. 16, the first sub-region AA1_1 of the first region A1_1 may include a plurality of first pixels PX1 sequentially arranged along the second direction DR2 on the first column C1 and the second column C2, respectively, and a plurality of second pixels PX2 sequentially arranged along the second direction DR2 on the third column C3. In this way, when a plurality of second pixels PX2 are arranged on the third column C3 which is one of the three columns C1, C2, C3, and a plurality of first pixels PX1 are arranged on the remaining two columns C1 and C2, it may be defined that the plurality of second pixels PX2 are arranged at the first pixel density on the first sub-region AA1_1.

[0260] Further, the second sub-region AA2_1 of the first region A1_1 may include a plurality of first pixels PX1 sequentially arranged along the second direction DR2 on the fourth column C4, the fifth column C5, the sixth column C6, and the seventh column C7, respectively, and a plurality of second pixels PX2 sequentially arranged along the second direction DR2 on the eighth column C8. In this way, when a plurality of second pixels PX2 are arranged on one of the five columns C4, C5, C6, C7, C8, i.e., the eighth column C8, and a plurality of first pixels PX1 are arranged on the remaining four columns C4 to C7, the second sub-region AA2_1 may be defined such that the plurality of second pixels PX2 are arranged at the second pixel density. Here, as described above, the second pixel density of the second sub-region AA2_1 may be lower than the first pixel density of the first sub-region AA1_1.

[0261] Also, only a plurality of first pixels PX1 may be arranged on a region excluding the first and second sub-regions AA1_1 and AA2_1 where the second pixels PX2 are arranged in the first region A1_1. For example, a plurality of first pixels PX1 may be sequentially arranged along the second direction DR2 on a plurality of columns on the third sub-region AA3_1 including the ninth column C9, the tenth column C10, the eleventh column C11, the twelfth column C12, and the thirteenth column C13. In this way, when only a plurality of first pixels PX1 are arranged on a plurality of columns, the third sub-region AA3_1 may be defined such that the second pixels PX2 are arranged at the third pixel density. For example, the third pixel density of the third sub-region AA3_1 is lower than the second pixel density of the second sub-region AA2_1. For example, the third pixel density may have a value substantially equal to 0.

[0262] On the other hand, when the display device 100 is driven in the first mode or the second mode, each of the plurality of first pixels PX1 and the plurality of second pixels PX2 arranged on the first region A1_1 of the display panel PN may be driven in the first state or the third state.

[0263] For example, as described with reference to FIG. 14, when a plurality of first pixels PX1 and a plurality of second pixels PX2 arranged on the first region A1_1 are each driven in a first state, the first light-emitting elements ED1 included in each of the plurality of first pixels PX1 arranged on the first region A1_1 emit light to provide content within a first viewing angle, and the third light-emitting elements ED3 included in each of the plurality of second pixels PX2 emit light to provide content within the first viewing angle.

[0264] Also, as described with reference to FIG. 15, when a plurality of first pixels PX1 and a plurality of second pixels PX2 arranged on the first region A1_1 are each driven in a third state, all of the first light-emitting element ED1 and the second light-emitting element ED2 included in each of the plurality of first pixels PX1 arranged on the first region A1_1 emit light to provide content within a first viewing angle, and all of the third light-emitting element ED3 and the fourth light-emitting element ED4 included in each of the plurality of second pixels PX2 emit light to provide content within the first viewing angle.

[0265] When the display device 100 is driven in the first mode or the second mode, each of the plurality of first pixels PX1 and the plurality of second pixels PX2 arranged on the first region A1_1 of the display panel PN is driven in the first state or the third state. For the specific driving method in which content within the first viewing angle is provided on the first region A1_1, since it is substantially the same as or similar to the driving method in which each of the plurality of first pixels PX1 and the plurality of second pixels PX2 arranged on the first region A1 in FIGS. 14 and 15 is driven in the first state or the third state to provide content within the first viewing angle on the first region A1, repeated descriptions will not be repeated.

[0266] FIG. 17 is a diagram showing another example of the first region of the display panel of FIG. 11.

[0267] FIG. 17 shows a modified embodiment with respect to the embodiment of FIG. 12 in relation to the pixel density of the second pixel PX2 arranged on the first region A1_2. Accordingly, in FIG. 17, in order to avoid repeated descriptions, the description will focus on the points different from the above-described embodiments.

[0268] In FIG. 17, an example of the first region A1_2 included in the display panel PN of FIG. 11 is shown.

[0269] Referring to FIG. 17, the first region A1_2 of the display panel PN can include first to third sub-regions AA1_2, AA2_2, and AA3_2 that are sequentially arranged along the first direction DR1. For example, the second sub-region AA2_2 can be arranged adjacent to the first sub-region AA1_2 along the first direction DR1, and the third sub-region AA3_2 can be arranged adjacent to the second sub-region AA2_2 along the first direction DR1.

[0270] Referring to FIGS. 11 and 17, the first and second sub-regions AA1_2 and AA2_2 of the first region A1_2 are defined as a part of the first region A1_2 that is adjacent to the second region A2, and the third sub-region AA3_2 can be defined as the remaining region of the first region A1_2 excluding the first and second sub-regions AA1_2 and AA2_2. Here, the first and second sub-regions AA1_2 and AA2_2, which are a part of the first region A1_2 adjacent to the second region A2 shown in FIG. 17, are exemplary, and a part of the first region A1_2 adjacent to the second region A2 can be variously set according to the design of the display panel PN.

[0271] Each of the first to third sub-regions AA1_2 to AA3_2 can include a plurality of pixels that are spaced apart from each other along the first direction DR1 and the second direction DR2.

[0272] The first to third sub-regions AA1_2 to AA3_2 can have different densities with respect to the second pixel PX2. That is, the second pixel PX2 can be arranged at different densities in the first to third sub-regions AA1_2 to AA3_2.

[0273] In the first region A1_2, the ratio of the area where the second pixels PX2 are arranged per unit area may decrease as going in the first direction DR1. For example, as going from the first sub-region AA1_2 to the third sub-region AA3_2, that is, as getting farther from the boundary between the first region A1_2 and the second region A2 within the first region A1_2, the ratio of the area where the second pixels PX2 are arranged per unit area may decrease.

[0274] For example, on the first sub-region AA1_2, a plurality of first pixels PX1 and a plurality of second pixels PX2 may be arranged, and the plurality of second pixels PX2 may be arranged at the first pixel density in the first sub-region AA1_2.

[0275] Also, on the second sub-region AA2_2, a plurality of first pixels PX1 and a plurality of second pixels PX2 may be arranged, and the plurality of second pixels PX2 may be arranged at a second pixel density lower than the first pixel density of the first sub-region AA1_2 in the second sub-region AA2_2.

[0276] Also, only a plurality of first pixels PX1 may be arranged on the third sub-region AA3_2. In other words, no second pixel PX2 is arranged on the third sub-region AA3_2, and the third pixel density where the second pixel PX2 is arranged on the third sub-region AA3_2 may be defined as 0.

[0277] More specifically, referring to FIG. 17, the first sub-region AA1_2 of the first region A1_2 may include a plurality of first pixels PX1 sequentially arranged along the second direction DR2 on the first column C1, the second column C2, and the third column C3, respectively, and a plurality of second pixels PX2 sequentially arranged along the second direction DR2 on the fourth column C4. In this way, when a plurality of second pixels PX2 are arranged on one of the four columns C1, C2, C3, C4, i.e., the fourth column C4, and a plurality of first pixels PX1 are arranged on the remaining three columns C1, C2, C3, it may be defined that the plurality of second pixels PX2 are arranged at the first pixel density on the first sub-region AA1_2.

[0278] Further, the second sub-region AA2_2 of the first region A1_2 can include a plurality of first pixels PX1 sequentially arranged along the second direction DR2 on the fifth column C5, sixth column C6, seventh column C7, eighth column C8, ninth column C9, and tenth column C10, and a plurality of second pixels PX2 sequentially arranged along the second direction DR2 on the tenth column C10 and the eleventh column C11 adjacent to the first direction DR1. In this way, when a plurality of second pixels PX2 are arranged on the eleventh column C11, which is one of the seven columns C5, C6, C7, C8, C9, C10, C11, and a plurality of first pixels PX1 are arranged on the remaining six columns C5, C6, C7, C8, C9, C10, the plurality of second pixels PX2 on the second sub-region AA2_2 can be defined as being arranged at the second pixel density. Here, as described above, the second pixel density of the second sub-region AA2_2 may be lower than the first pixel density of the first sub-region AA1_2.

[0279] Also, only a plurality of first pixels PX1 can be arranged on a region of the first region A1_2 excluding the first and second sub-regions AA1_2 and AA2_2 where the second pixels PX2 are arranged, for example, on the third sub-region AA3_2. For example, a plurality of first pixels PX1 can be sequentially arranged along the second direction DR2 on a plurality of columns on the third sub-region AA3_2 including the twelfth column C12 and the thirteenth column C13. In this way, when only a plurality of first pixels PX1 are arranged on a plurality of columns, the second pixels PX2 on the third sub-region AA3_2 can be defined as being arranged at the third pixel density. For example, the third pixel density of the third sub-region AA3_2 is lower than the second pixel density of the second sub-region AA2_2. For example, the third pixel density can have a value substantially equal to 0.

[0280] On the other hand, when the display device 100 is driven in the first mode or the second mode, each of the plurality of first pixels PX1 and the plurality of second pixels PX2 arranged on the first region A1_2 of the display panel PN can be driven in the first state or the third state.

[0281] For example, as described with reference to FIG. 14, when a plurality of first pixels PX1 and a plurality of second pixels PX2 arranged on the first region A1_2 are each driven in the first state, the first light-emitting elements ED1 included in each of the plurality of first pixels PX1 arranged on the first region A1_2 emit light to provide content with a first viewing angle, and the third light-emitting elements ED3 included in each of the plurality of second pixels PX2 emit light to provide content with a first viewing angle.

[0282] Also, as described with reference to FIG. 15, when a plurality of first pixels PX1 and a plurality of second pixels PX2 arranged on the first region A1_2 are each driven in the third state, all of the first light-emitting element ED1 and the second light-emitting element ED2 included in each of the plurality of first pixels PX1 arranged on the first region A1_2 emit light to provide content with a first viewing angle, and all of the third light-emitting element ED3 and the fourth light-emitting element ED4 included in each of the plurality of second pixels PX2 emit light to provide content with a first viewing angle.

[0283] When the display device 100 is driven in the first mode or the second mode, each of the plurality of first pixels PX1 and the plurality of second pixels PX2 arranged on the first region A1_2 of the display panel PN is driven in the first state or the third state. For the specific driving method in which content with a first viewing angle is provided on the first region A1_2, it is substantially the same as or similar to the driving method in which each of the plurality of first pixels PX1 and the plurality of second pixels PX2 arranged on the first region A1 shown in FIGS. 14 and 15 is driven in the first state or the third state and content with a first viewing angle is provided on the first region A1, so duplicate explanations will not be repeated.

[0284] FIG. 18 is a diagram showing another example of the first region of the display panel of FIG. 11.

[0285] FIG. 18 shows a modified example with respect to the embodiment of FIG. 12 in relation to the arrangement of the second pixels PX2 over the entire area of the first region A1_3. Accordingly, in FIG. 18, the description will focus on the differences from the above-described embodiments in order to avoid duplicate explanations.

[0286] In FIG. 18, an example of the first region A1_3 included in the display panel PN of FIG. 11 is shown.

[0287] Referring to FIG. 18, the first region A1_3 of the display panel PN can include first to nth sub-regions AA1_3 to AAn_3 that are sequentially arranged along the first direction DR1 (where n is an integer greater than 0). For example, the second sub-region AA2_3 can be arranged adjacent to the first sub-region AA1_3 along the first direction DR1. Also, the nth sub-region AAn_3 can be defined as the sub-region that is farthest from the second region A2 on the first region A1_3.

[0288] Not only a plurality of first pixels PX1 but also a plurality of second pixels PX2 can be arranged over the entire area of the first region A1_3. For example, each of the first to nth sub-regions AA1_3 to AAn_3 can include a plurality of first pixels PX1 and a plurality of second pixels PX2. As an example, each of the first to nth sub-regions AA1_3 to AAn_3 can include a plurality of first pixels PX1 and a plurality of second pixels PX2 that are spaced apart from each other along the first direction DR1 and the second direction DR2.

[0289] The first to nth sub-regions AA1_3 to AAn_3 can have different densities with respect to the second pixel PX2. That is, the second pixels PX2 can be arranged at different densities in the first to nth sub-regions AA1_3 to AAn_3.

[0290] The ratio of the area where the second pixel PX2 is arranged per unit area can decrease as going in the first direction DR1 within the first region A1_3. For example, as going from the first sub-region AA1_3 to the nth sub-region AAn_3, that is, as getting farther from the boundary between the first region A1_3 and the second region A2 within the first region A1_3, the ratio of the area where the second pixel PX2 is arranged per unit area can decrease.

[0291] For example, on the first sub-region AA1_3, a plurality of first pixels PX1 and a plurality of second pixels PX2 are arranged, and the plurality of second pixels PX2 can be arranged at the first pixel density in the first sub-region AA1_3. Here, the first pixel density at which the plurality of second pixels PX2 are arranged on the first sub-region AA1_3 can be substantially the same as or similar to the first pixel density at which the plurality of second pixels PX2 are arranged on the first sub-region AA1 of the first region A1 described with reference to FIG. 12. Therefore, redundant explanations will not be repeated.

[0292] Also, on the second sub-region AA2_3, a plurality of first pixels PX1 and a plurality of second pixels PX2 are arranged, and the plurality of second pixels PX2 can be arranged at a second pixel density lower than the first pixel density in the second sub-region AA2_3. Here, the second pixel density at which the plurality of second pixels PX2 are arranged on the second sub-region AA2_3 can be substantially the same as or similar to the second pixel density at which the plurality of second pixels PX2 are arranged on the second sub-region AA2 of the first region A1 described with reference to FIG. 12. Therefore, redundant explanations will not be repeated.

[0293] Also, on the nth sub-region AAn_3, a plurality of first pixels PX1 and a plurality of second pixels PX2 are arranged, and the plurality of second pixels PX2 can be arranged at a fourth pixel density lower than the second pixel density in the nth sub-region AAn_3.

[0294] More specifically, the n-th sub-region AAn_3 of the first region A1_3 includes a plurality of first pixels PX1 sequentially arranged along the second direction DR2 on a plurality of columns including the (m-2)-th column Cm-2 (where m is an integer greater than 0) and the (m-1)-th column Cm-1 adjacent to the (m-2)-th column Cm-2 in the first direction DR1, excluding the m-th column Cm adjacent to the (m-1)-th column Cm-1 in the first direction DR1 on the n-th sub-region AAn_3, and a plurality of second pixels PX2 sequentially arranged along the second direction DR2 on the m-th column Cm. In this way, when a plurality of second pixels PX2 are arranged on one of the plurality of columns Cm-2, Cm-1, Cm excluding the m-th column Cm, and a plurality of first pixels PX1 are arranged on the remaining columns Cm-2, Cm-1, it can be defined that the plurality of second pixels PX2 are arranged at the fourth pixel density on the n-th sub-region AAn_3. Here, as described above, the fourth pixel density may be lower than the second pixel density.

[0295] In this way, in the case of the first region A1_3 included in the display panel PN of the display device 100 according to the embodiment of FIG. 18, the second pixels PX2 can be arranged over the entire region of the first region A1_3.

[0296] On the other hand, when the display device 100 is driven in the first mode or the second mode, each of the plurality of first pixels PX1 and the plurality of second pixels PX2 arranged on the first region A1_3 of the display panel PN can be driven in the first state or the third state.

[0297] For example, as described with reference to FIG. 14, when each of the plurality of first pixels PX1 and the plurality of second pixels PX2 arranged on the first region A1_3 are driven in the first state, the first light-emitting elements ED1 included in each of the plurality of first pixels PX1 arranged on the first region A1_3 emit light to provide content within the first viewing angle, and the third light-emitting elements ED3 included in each of the plurality of second pixels PX2 emit light to provide content within the first viewing angle.

[0298] Also, as described with reference to FIG. 15, when a plurality of first pixels PX1 and a plurality of second pixels PX2 disposed on the first region A1_3 are each driven in the third state, all of the first light emitting elements ED1 and the second light emitting elements ED2 included in each of the plurality of first pixels PX1 disposed on the first region A1_3 emit light to provide content with a first viewing angle, and all of the third light emitting elements ED3 and the fourth light emitting elements ED4 included in each of the plurality of second pixels PX2 emit light to provide content with a first viewing angle.

[0299] When the display device 100 is driven in the first mode or the second mode, each of the plurality of first pixels PX1 and the plurality of second pixels PX2 disposed on the first region A1_3 of the display panel PN is driven in the first state or the third state. For the specific driving method in which content with a first viewing angle is provided on the first region A1_1, refer to FIGS. 14 and 15, in which each of the plurality of first pixels PX1 and the plurality of second pixels PX2 disposed on the first region A1 is driven in the first state or the third state to provide content with a first viewing angle on the first region A1. Since it is substantially the same as or similar to the driving method, repeated explanations will not be given.

[0300] As described above, like the display device 100 according to an embodiment of the present specification, not only the first pixel PX1 including only the first type of lens 161 that refracts light at the first viewing angle on the first region A1 that provides content at the first viewing angle, but also a lens structure such as the third pixel PX3 disposed on the second region A2, that is, the first pixel PX1 and the second pixel PX2 including the first type of lens 161 and the second type of lens 162 that refracts light at the second viewing angle are arranged together, so that the problem of the boundary between the first region A1 and the second region A2 being visible can be minimized.

[0301] Also, compared to the first state where only the light-emitting elements ED1 and ED2 included in the first pixel PX1 and the light-emitting elements ED3 and ED4 included in the second pixel PX2 emit light on the first region A1 that provides content at the first viewing angle, when each of the first pixel PX1 and the second pixel PX2 is driven in the third state, content is provided at the first viewing angle as in the first state. However, since all the light-emitting elements emit light, the luminance of the corresponding content can increase. That is, based on the same data signal being written, the luminance when the first region A1 is driven in the third state may be higher than the luminance when driven in the first state. Thereby, the power consumption for increasing the luminance can be improved.

[0302] The display device according to an embodiment of the present invention can be described as follows.

[0303] The display device according to an embodiment of the present specification can include a display panel partitioned into a first region including a plurality of first pixels and a plurality of second pixels, and a second region adjacent to the first region in the direction opposite to the first direction and including a plurality of third pixels.
