[0026] Considering the functionality of this invention, the terms used in the embodiments have been selected from currently widely used general terminology; however, they may be varied according to the intent of a person skilled in the art, promotion, the emergence of new technologies, etc. If necessary, the applicant may choose any specific term. In such cases, the meaning of the term will be described in detail in the corresponding specification. Therefore, the terminology used in this invention should be defined based on its content and meaning throughout the invention, rather than simply its name.

[0027] When a part of an invention includes a certain element, it means that other components are not excluded, but may be further included unless otherwise specified.

[0028] The expression "at least one of A, B, and C" described throughout the invention may include "A alone," "B alone," "C alone," "A and B," "A and C," "B and C," or "all of A, B, and C." The advantages and features of the invention, as well as its implementation methods, will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

[0029] The shapes, dimensions, proportions, angles, and quantities disclosed in the accompanying drawings to describe various embodiments of the invention are merely examples, and the invention is therefore not limited to the details shown. Similar reference numerals refer to similar elements throughout. In the following description, detailed descriptions of related known functions or constructions will be omitted or may be briefly discussed when it is determined that such detailed descriptions would unnecessarily obscure the focus of the invention.

[0030] Where the terms "including," "having," and "comprise" are used in this specification, other parts may also exist, unless "only" is used. Singular terms may include plural forms unless otherwise specified. When interpreting an element, although not explicitly stated, the element should be interpreted as including the error region.

[0031] When describing positional relationships, such as when the positional order is described as "above," "over," "below," "below," "after," etc., situations where they do not touch may be included, unless the word "directly" is used. For example, if it is mentioned that the first element is "above" the second element, it does not mean that the first element must be or is directly above the second element in the drawing.

[0032] It will be understood that although the terms "first," "second," etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another and do not limit any order or sequence. For example, without departing from the scope of the invention, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

[0033] For ease of illustration, the area, length, or thickness of each element described in this specification is illustrated; however, the invention is not necessarily limited to the area and thickness of the illustrated construction.

[0034] The features of the various embodiments of the present invention can be combined or integrated with each other, either partially or entirely, and can be interoperable and driven in various ways, as will be fully understood by those skilled in the art. The various embodiments of the present invention can be implemented independently of each other, or can be implemented together in an interdependent relationship.

[0035] The terms used in this invention are selected from those generally known and adopted, which will be described later, but may be modified according to the intentions, practices, etc. of the user or operator. Therefore, the terminology used herein should be defined by the specification disclosed herein.

[0036] The transistors constituting the pixel circuits in this invention may include at least one of oxide thin-film transistors (TFTs), amorphous silicon TFTs (a-Si TFTs), and low-temperature polycrystalline silicon (LTPS) TFTs.

[0037] The embodiments described below will be based on organic light-emitting display devices. However, the embodiments of the present invention are not limited to organic light-emitting display devices, but can be applied to inorganic light-emitting display devices that include inorganic light-emitting materials. For example, the embodiments of the present invention can be applied to quantum dot display devices.

[0038] It will be understood that terms such as “first,” “second,” and “third” are used only to distinguish one element from another in each implementation, and the implementation is not limited by these terms. Therefore, the same term may refer to different elements based on the implementation.

[0039] In the following description, embodiments of the present invention will be described with reference to the accompanying drawings.

[0040] Figure 1 This is a view illustrating an example of a display device according to an embodiment of the present invention.

[0041] Display device 100 may be disposed in at least a portion of a vehicle to provide at least one type of content. For example, display device 100 may be disposed on at least a portion of a vehicle dashboard. The vehicle dashboard includes components disposed on the front surface of the vehicle's front seats (e.g., driver's seat and passenger seat). For example, input components for controlling various functions within the vehicle (e.g., air conditioning, audio system, and navigation system) may be disposed on the vehicle dashboard.

[0042] In one embodiment, the display device 100 may be mounted on the vehicle dashboard and may be used as an input unit for at least some of the various functions of the vehicle. The display device 100 may provide various vehicle-related information, such as driving information (e.g., the vehicle's current speed, remaining fuel, and driving distance) and information about vehicle components (e.g., tire damage).

[0043] In one embodiment, the display device 100 may be positioned across the driver's seat and passenger seat located in the front seats of the vehicle. Users of the display device 100 may include the vehicle driver and passengers in the vehicle's passenger seats. That is, both the vehicle's driver and passengers can use the display device 100.

[0044] In the implementation method, Figure 1 Only a portion of the display device 100 may be shown in the image. Figure 1 The display device 100 shown may correspond to a display panel among the various components included in the display device 100. As a specific example, Figure 1 The display device 100 shown can display at least a portion of the display area or non-display area of ​​a display panel. Among the components of the display device 100, besides... Figure 1 Components other than those shown may be encapsulated inside (or at least part of) the vehicle.

[0045] Figure 2 This is a functional block diagram illustrating a display device according to an embodiment of the present invention.

[0046] The display device according to one embodiment of the present invention may be an electroluminescent display device. The electroluminescent display device may be an organic light-emitting diode (OLED) display device, a quantum dot OLED display device, or an inorganic light-emitting diode (LED) display device.

[0047] Reference Figure 2 The display device may include a display panel DP, a data driver DD, a gate driver GD, a timing controller TC, and a power supply unit PU.

[0048] In this implementation, the display panel DP can generate an image to be provided to the user. For example, the display panel DP can generate and display the image to be provided to the user via a pixel area PA provided with pixel circuitry.

[0049] The data driver DD, gate driver GD, timing controller TC, and power supply unit PU can be supplied with signals for operating each pixel area PA via signal lines. These signal lines may include, for example, data lines DL, gate lines GL, and power supply lines PL, such as... Figure 3 As shown.

[0050] For example, the data driver DD can apply a data signal to each pixel area PA via the data line DL, the gate driver GD can apply a gate signal to each pixel area PA via the gate line GL, and the power supply unit PU can provide a power supply voltage to each pixel area PA via the power supply voltage supply line PL.

[0051] The timing controller TC controls the data driver DD and the gate driver GD. For example, the timing controller TC rearranges the digital video data input from the outside according to the resolution of the display panel DP, and provides the rearranged digital video data to the data driver DD.

[0052] The data driver DD can convert digital video data input from the timing controller TC into analog data voltage based on data control signals, and provide the analog data voltage to multiple data lines.

[0053] The gate driver (GD) can generate scan signals and light emission signals (or light emission control signals) based on gate control signals. The gate driver (GD) may include a scan driver and a light emission signal driver. The scan driver or scan output unit can generate scan signals in a row-sequential manner to drive at least one scan line connected to each pixel row and provide the scan signals to the scan lines. The light emission signal driver can generate light emission signals in a row-sequential manner to drive at least one light emission signal line connected to each pixel row and provide the light emission signal to the light emission signal line.

[0054] According to an embodiment, the gate driver GD can be disposed on the display panel DP using an in-panel gate driver (GIP) method. For example, the gate driver GD can be divided into multiple gate drive circuits GD, which are then disposed on at least two sides of the display panel DP.

[0055] The display area AA of the display panel DP may include multiple pixel areas PA (or pixels or pixel circuits). Multiple data lines (e.g.) Figure 3 The data line DL is connected to multiple gate lines (e.g., in the pixel area PA) in the pixel area PA. Figure 3 The gate lines (GL) intersect, and sub-pixels disposed in each intersection region may be included in a pixel region PA. The corresponding sub-pixels included in a pixel region PA may emit light of a corresponding color that is different from each other. For example, a pixel region PA may achieve blue, red, and green by using three sub-pixels, but is not limited thereto. Depending on the specific case, the pixel region PA may further include sub-pixels for further implementing a specific color (e.g., white).

[0056] In pixel region PA, the area that realizes blue can be called the blue sub-pixel region, the area that realizes red can be called the red sub-pixel region, and the area that realizes green can be called the green sub-pixel region.

[0057] In an implementation, the pixel region PA may include a plurality of sub-pixels. Each of the plurality of sub-pixels may be divided into a first lens region and a second lens region that provide corresponding viewing angles different from each other. For example, the pixel region PA may include a first lens region that provides light to a first range to form a first viewing angle and a second 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.

[0058] The non-display area BZ can be disposed along the periphery of the display area. Components for driving the pixel circuitry disposed in the pixel area PA can be disposed in the non-display area BZ. For example, at least a portion of the gate driver GD can be disposed in the non-display area BZ. The non-display area BZ can be referred to as the border area.

[0059] Figure 3 An example of a pixel circuit of a display device according to an embodiment of the present invention is shown. The pixel area PA may include a plurality of sub-pixels that present different colors and a pixel circuit corresponding to each of the plurality of sub-pixels. Figure 3 An example of a pixel circuit corresponding to a sub-pixel set in pixel region PA is shown.

[0060] Reference Figure 3 The pixel circuit may include: multiple transistors DT, ST, ET1 and ET2; capacitor Cst; and multiple light-emitting elements 310 and 320.

[0061] The driving transistor DT and capacitor Cst can be connected to the switching transistor ST. The first electrode of the driving transistor DT can be connected to the power supply voltage line PL.

[0062] A switching transistor ST can be connected to the gate line GL to receive 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 line DL. In this case, a data signal can be provided to the gate of the drive transistor DT via the switching transistor ST in response to the switching transistor ST being turned on.

[0063] A capacitor Cst can be placed between the gate and the second electrode of the driving transistor DT. The capacitor Cst can hold the signal applied to the gate of the driving transistor DT, such as a data signal, for one frame.

[0064] According to the embodiments, the driving transistor DT, the switching transistor ST, and the capacitor Cst can be components used to drive light-emitting elements (e.g., the first light-emitting diode 310 and the second light-emitting diode 320), and can be referred to as a driving section, but are not limited to these terms.

[0065] A first light-emitting diode (or first light-emitting element) 310 can be connected to a first transistor ET1 that is turned on or off by a first light-emitting signal EM1. A second light-emitting diode 320 (or second light-emitting element) can be connected to a second transistor ET2 that is turned on or off by a second light-emitting signal EM2. The first transistor ET1 can be referred to as the first light-emitting control transistor. The second transistor ET2 can be referred to as the second light-emitting control transistor.

[0066] In this scenario, the first light-emitting element 310 or the second light-emitting element 320 can be connected to other elements of the pixel circuit, such as a driving transistor DT, depending on the mode. The mode can be specified by user input or determined when predetermined conditions are met. For example, when a predetermined first condition is met, the first light-emitting element 310 can emit light based on the provision of a first light-emitting signal EM1. When a predetermined second condition is met, the second light-emitting element 320 can emit light based on the provision of a second light-emitting signal EM2. The first condition may include predetermined conditions for driving a first mode. The second condition may include predetermined conditions for driving a second mode.

[0067] Figure 3 The multiple transistors DT, ST, ET1, and ET2 may comprise at least one of amorphous silicon, polycrystalline silicon, and oxide semiconductors such as IGZO. The first or second electrode of the transistor may be a source or a drain. For example, the first electrode may be a source, and the second electrode may be a drain. As another example, the first electrode may be a drain, and the second electrode may be a source.

[0068] Figure 4This is a view illustrating an example of a pixel array in a display device according to an embodiment of the present invention.

[0069] Reference Figure 4 Multiple horizontal pixel lines L1, L2, L3, and L4 can be set on the display panel (e.g., Figure 2 In the pixel array of the display panel (DP), multiple pixels PXL, which are horizontally adjacent to each other and jointly connected to gate lines (e.g., scan line 410, first light-emitting signal line 420 and second light-emitting signal line 425), can be arranged in each of multiple horizontal pixel lines L1, L2, L3 and L4.

[0070] In this scenario, each of the multiple horizontal pixel lines L1, L2, L3, and L4 can refer to multiple pixels PXL arranged on a line implemented by horizontally adjacent pixels PXL. The pixel array may include a first power line 430 for providing a high-potential power supply voltage ELVDD to the pixels PXL and a second power line 440 for providing a reference voltage Vref to the pixels PXL. Furthermore, the pixels PXL may be connected to a low-potential power supply voltage ELVSS (see...). Figure 5 ).

[0071] In an embodiment, the gate line may include a scan line 410 provided with a scan signal Scan, a common light emission signal line 415 provided with a common light emission signal EM0, a first light emission signal line 420 provided with a first light emission signal EM1, and a second light emission signal line 425 provided with a second light emission signal EM2.

[0072] Pixel PXL can emit light of at least one color. For example, pixel PXL can emit any one of red, green, blue, and white light. Pixels PXL can constitute a unit pixel, and the color realized in the unit pixel can be determined according to the emission ratio of red, green, blue, and white. Data line 450, scan line 410, common emission signal line 415, first emission signal line 420, second emission signal line 425, first power line 430, and second power line 440 can be connected to each pixel PXL.

[0073] Figure 5 and 6 This is a view illustrating an example of the pixel circuitry of a display device according to an embodiment of the present invention. Specifically, Figure 5 and 6 An example of a pixel circuit including a unit pixel PXL in a pixel array is shown.

[0074] Reference Figure 5The pixel circuit 500 may include twelve (12) transistors and a capacitor. At least a portion of the twelve transistors included in the pixel circuit 500 may be n-type transistors or p-type transistors. In the case of p-type transistors, the low-level voltage of each drive signal refers to the voltage used to turn on the TFT, and the high-level voltage of each drive signal may refer to the voltage used to turn off the TFT.

[0075] A low-level voltage may correspond to a predetermined voltage lower than a high-level voltage. For example, a low-level voltage may include a voltage corresponding to the range of -8V to -12V. A high-level voltage may correspond to a predetermined voltage higher than a low-level voltage. For example, a high-level voltage may include a voltage corresponding to the range of 6V to 8V. According to one embodiment, a low-level voltage may refer to a first voltage, and a high-level voltage may be referred to as a second voltage. In this case, the first voltage may be a value lower than the second voltage.

[0076] The first electrode or second electrode of the transistor described below may refer to either the source or the drain. However, using terms such as first electrode and second electrode to distinguish each electrode does not limit which electrode corresponds to which electrode. Furthermore, the first electrode may not refer to the same electrode for every electrode. For example, the first electrode of the first transistor T1 may refer to the source of the first transistor T1, and the first electrode of the sixth transistor T6 may refer to the drain of the sixth transistor T6.

[0077] The driving transistor DT can be connected to a first transistor T1 connected to a first light-emitting element ED1 and a second transistor T2 connected to a second light-emitting element ED2. For example, the first electrode of the driving transistor DT can be connected to the first transistor T1 and the second transistor T2. Depending on the connection between the gate of the first transistor T1 and the first light-emitting signal line 420, the first transistor T1 can be turned on or off by the first light-emitting signal EM1. Depending on the connection between the gate of the second transistor T2 and the second light-emitting signal line 425, the second transistor T2 can be turned on or off by the second light-emitting signal EM2. The first light-emitting signal line 420 can correspond to the gate line used to provide the first light-emitting signal EM1. The second light-emitting signal line 425 can correspond to the gate line used to provide the second light-emitting signal EM2.

[0078] Figure 5 The first light-emitting signal EM1 may correspond to the nth first light-emitting signal EM1(n) provided to the nth row in response to the pixel circuit 500 being positioned in the nth pixel row. The second light-emitting signal EM2 may correspond to the nth second light-emitting signal EM2(n) provided to the nth row in response to the pixel circuit 500 being positioned in the nth pixel row.

[0079] The driving transistor DT can be connected to at least one of the first transistor T1, the second transistor T2, the third transistor T3, the fourth transistor T4, the sixth transistor T6, the seventh transistor T7, and the capacitor C1. For example, the first electrode of the driving transistor DT can be connected to the first transistor T1, the second transistor T2, the third transistor T3, and the capacitor C1. The second electrode of the driving transistor DT can be connected to the sixth transistor T6 and the seventh transistor T7.

[0080] The first transistor T1 can be connected to at least one of the first light-emitting element ED1, the second transistor T2, the third transistor T3, the (5-1)th transistor T51, and the driving transistor DT. For example, the first electrode of the first transistor T1 can be connected to the driving transistor DT and the third transistor T3. The second electrode of the first transistor T1 can be connected to the (5-1)th transistor T51 and the first light-emitting element ED1. The gate of the first transistor T1 can be connected to the first light-emitting signal line 420 for providing the first light-emitting signal EM1. Therefore, the first transistor T1 can be turned on or off by providing the first light-emitting signal EM1. When the first transistor T1 is turned on, the voltage of the driving transistor DT can be applied to the first light-emitting element ED1 (e.g., the anode of the first light-emitting element ED1).

[0081] The second transistor T2 can be connected to at least one of the second light-emitting element ED2, the first transistor T1, the third transistor T3, the (5-2)th transistor T52, and the driving transistor DT. The first electrode of the second transistor T2 can be connected to the driving transistor DT and the third transistor T3. The second electrode of the second transistor T2 can be connected to the second light-emitting element ED2 and the (5-2)th transistor T52. The gate of the second transistor T2 can be connected to the second light-emitting signal line 425 for providing the second light-emitting signal EM2. Therefore, the second transistor T2 can be turned on or off based on the provision of the second light-emitting signal EM2. When the second transistor T2 is turned on, the voltage of the driving transistor DT can be applied to the second light-emitting element ED2 (e.g., the anode of the second light-emitting element ED2).

[0082] A first lens may be disposed on a first light-emitting element ED1. In this case, the viewing angle of the area where the first light-emitting element ED1 is disposed may have a first value or a greater value. A second lens may be disposed on a second light-emitting element ED2. In this case, the viewing angle of the area where the second light-emitting element ED2 is disposed may have a value less than the first value. The viewing angle of the area where the first light-emitting element ED1 is disposed may be wider than the viewing angle of the area where the second light-emitting element ED2 is disposed. For example, the area where the first light-emitting element ED1 is disposed may provide light to the area corresponding to the driver's seat and the passenger seat. The area where the second light-emitting element ED2 is disposed may provide light to the area corresponding to the passenger seat, excluding the driver's seat.

[0083] The third transistor T3 may be connected to at least one of the driving transistor DT, the first transistor T1, the second transistor T2, the fourth transistor T4, and the capacitor C1. For example, the first electrode of the third transistor T3 may be connected to the fourth transistor T4, the capacitor C1, and the driving transistor DT. The second electrode of the third transistor T3 may be connected to the first transistor T1, the second transistor T2, and the driving transistor DT. The gate of the third transistor T3 may be connected to a capacitor C1 for use in a configuration where... Figure 5 In the row of the pixel circuit, that is, in the nth row, the nth scan line provides the scan signal Scan. Therefore, the third transistor T3 can be provided with the nth scan signal Scan(n), and can be turned on or off by the nth scan signal Scan(n).

[0084] The fourth transistor T4 may be connected to at least one of the driving transistor DT, the third transistor T3, the (5-1)th transistor T51, the (5-2)th transistor T52, and the capacitor C1. For example, the first electrode of the fourth transistor T4 may be connected to the third transistor T3, the capacitor C1, and the driving transistor DT.

[0104] Figure 7 A plane of a portion of a display device according to an embodiment of the present invention is shown. Figure 7 The plane of pixel region PA is shown when three sub-pixels are set in pixel region PA. Figure 8 It is along Figure 7 A sectional view taken by line I-I'; Figure 9 It is along Figure 7 The sectional view taken from line II-II'. (Refer to...) Figures 7 to 9 The following description is provided.

[0105] exist Figure 7 In this design, the pixel area PA may include a blue sub-pixel area BPA for achieving blue, a red sub-pixel area RPA for achieving red, and a green sub-pixel area GPA for achieving green. According to an implementation, the blue sub-pixel area BPA may correspond to a first sub-pixel, the red sub-pixel area RPA may correspond to a second sub-pixel, and the green sub-pixel area GPA may correspond to a third sub-pixel. Pixel circuits may correspond to each sub-pixel. A corresponding pixel circuit may be provided for each sub-pixel.

[0106] Pixel region PA may include first lens regions BWE, RWE, GWE and second lens regions BNE, RNE, GNE that provide different viewing angles. The second lens regions BNE, RNE, GNE of each pixel region PA can operate independently of the corresponding first lens regions BWE, RWE, GWE. For example, each pixel region PA may include a first light-emitting element 310 (e.g., ...) located on the first lens region (e.g., BWE, RWE, GWE) of the corresponding pixel region PA. Figure 3 The first light-emitting element 310) and the second light-emitting element 320 located on the second lens areas BNE, RNE, GNE of the corresponding pixel area PA (e.g. Figure 3 (the second light-emitting element 320).

[0107] The first light-emitting element 310 can emit light of a specific color. For example, the first light-emitting element 310 may include a first lower electrode 311, a first light-emitting layer 312, and a first upper electrode 313 sequentially stacked on the substrate 10. The substrate 10 may include an insulating material. The substrate 10 may include a transparent material. For example, the substrate 10 may include glass or plastic.

[0108] The first lower electrode 311 may include a conductive material. The first lower electrode 311 may include a material with high reflectivity. For example, the first lower electrode 311 may include metals such as aluminum (Al) and silver (Ag). The first lower electrode 311 may have a multilayer structure. For example, the first lower electrode 311 may have a structure in which a reflective electrode made of metal is located between transparent electrodes made of transparent conductive materials such as ITO and IZO.

[0109] The first light-emitting layer 312 can generate light with a brightness corresponding to the voltage difference between the first lower electrode 311 and the first upper electrode 313. For example, the first light-emitting layer 312 may include a light-emitting material layer (EML) having a light-emitting material. The light-emitting material may include organic materials, inorganic materials, or mixed materials.

[0110] The first light-emitting layer 312 may have a multilayer structure. For example, the first light-emitting layer 312 may further include at least one of a hole injection layer HIL, a hole transport layer HTL, an electron transport layer ETL, and an electron injection layer EIL.

[0111] The first upper electrode 313 may include a conductive material. The first upper electrode 313 may include a material different from that of the first lower electrode 311. The transmittance of the first upper electrode 313 may be higher than that of the first lower electrode 311. For example, the first upper electrode 313 may be a transparent electrode made of a transparent conductive material such as indium tin oxide (ITO) and indium zinc oxide (IZO). Therefore, in a display device according to an embodiment of the present invention, light generated by the first light-emitting layer 312 can pass through the first upper electrode 313 and be emitted.

[0112] The second light-emitting element 320 can achieve the same color as the first light-emitting element 310. The second light-emitting element 320 can have the same structure as the first light-emitting element 310. For example, the second light-emitting element 320 may include a second lower electrode 321, a second light-emitting layer 322, and a second upper electrode 323 stacked sequentially on the substrate 10.

[0113] The second lower electrode 321 may correspond to the first lower electrode 311, the second light-emitting layer 322 may correspond to the first light-emitting layer 312, and the second upper electrode 323 may correspond to the first upper electrode 313. For example, the second lower electrode 321 with respect to the second light-emitting element 320 may be formed with the same structure as the first lower electrode 311, and this may be equally applied to the second light-emitting layer 322 and the second upper electrode 323. That is, the first light-emitting element 310 and the second light-emitting element 320 may be formed with the same structure, but the present invention is not limited thereto. Depending on the specific circumstances, at least some elements of the first light-emitting element 310 and the second light-emitting element 320 may be configured differently from each other.

[0114] In one embodiment, the second light-emitting layer 322 may be separated from the first light-emitting layer 312. Therefore, in the display device according to an embodiment of the present invention, light emission due to leakage current can be avoided. Furthermore, in a display device according to one embodiment of the present invention, light can be generated only in one of the first light-emitting layer 312 and the second light-emitting layer 322, depending on user selection or predetermined conditions.

[0115] In the implementation, the first light-emitting element 310 and the second light-emitting element 320 of the pixel area PA may be located in the driving part of the corresponding pixel area PA (e.g., Figure 3 The first light-emitting element 310 and the second light-emitting element 320 of each pixel region PA are disposed on the driving unit 205 of the corresponding pixel region PA. For example, at least one insulating film (e.g., element buffer film 110, gate insulating film 120, interlayer insulating film 130, lower passivation film 140 and coating layer 150) is located on the substrate 10, and the first light-emitting element 310 and the second light-emitting element 320 of each pixel region PA can be disposed on one of the insulating films. Therefore, in a display device according to an embodiment of the present invention, the first light-emitting element 310 and the second light-emitting element 320 of each pixel region PA can be prevented from being unnecessarily connected to the driving unit 205 of the corresponding pixel region PA.

[0116] In this embodiment, the element buffer film 110, the gate insulating film 120, the interlayer insulating film 130, the lower passivation film 140, and the coating layer 150 may be stacked on the substrate 10. The element buffer film 110 may include an insulating material. For example, the element buffer film 110 may include an inorganic insulating material such as silicon oxide (SiO) or silicon nitride (SiN). The element buffer film 110 may have a multilayer structure. For example, the element buffer film 110 may have a stacked structure of a film made of silicon nitride (SiN) and a film made of silicon oxide (SiO).

[0117] In one embodiment, the component buffer film 110 may be located between the substrate 10 and the driving portion 205 of each pixel region PA. The component buffer film 110 prevents the substrate 10 from being contaminated during the process of forming the driving portion 205. For example, the upper surface of the substrate 10 facing the driving portion 205 of each pixel region PA may be covered by the component buffer film 110. The driving portion 205 of each pixel region PA may be located on the component buffer film 110.

[0118] In some embodiments, the gate insulating film 120 may include an insulating material. For example, the gate insulating film 120 may include an inorganic insulating material such as silicon oxide (SiO) or silicon nitride (SiN). The gate insulating film 120 may include a material having a high dielectric constant. For example, the gate insulating film 120 may include a high-k material such as hafnium oxide (HfO). The gate insulating film 120 may have a multilayer structure.

[0119] The gate insulating film 120 may be located on the element buffer film 110. The gate insulating film 120 may extend between the semiconductor pattern and the gate of the transistor. For example, the gates of the driving transistor DT and the switching transistor ST may be insulated from the semiconductor patterns of the driving transistor DT and the switching transistor ST via the gate insulating film 120. The gate insulating film 120 may cover the first semiconductor pattern and the second semiconductor pattern of each pixel region PA. The gates of the driving transistor DT and the switching transistor ST may be disposed on the gate insulating film 120.

[0120] Interlayer insulating film 130 may include an insulating material. For example, interlayer insulating film 130 may include an inorganic insulating material such as silicon oxide (SiO) or silicon nitride (SiN). Interlayer insulating film 130 may be located on gate insulating film 120. Interlayer insulating film 130 may extend between the gate and source of each of the driving transistor DT and the switching transistor ST, and between the gate and drain. For example, the source and drain of each of the driving transistor DT and the switching transistor ST may be insulated from the gate by interlayer insulating film 130. Interlayer insulating film 130 may cover the gate of each of the driving transistor DT and the switching transistor ST. The source and drain of each pixel region PA may be disposed on interlayer insulating film 130. Gate insulating film 120 and interlayer insulating film 130 may expose the source and drain regions of each semiconductor pattern located in each pixel region PA.

[0121] In this embodiment, the lower passivation film 140 may include an insulating material. For example, the lower passivation film 140 may include inorganic insulating materials such as silicon oxide (SiO) and silicon nitride (SiN). The lower passivation film 140 may be located on the interlayer insulating film 130. The lower passivation film 140 prevents the driving portion 205 from being damaged by external moisture and impact. The lower passivation film 140 may extend along the surfaces of the driving transistor DT and the switching transistor ST that are opposite to the substrate 10. The lower passivation film 140 may be in contact with the interlayer insulating film 130 on the outside of the driving portion 205 located in each pixel region PA.

[0122] The coating layer 150 may include an insulating material. The coating layer 150 may include a material different from the material of the lower passivation film 140. For example, the coating layer 150 may include an organic insulating material. The coating layer 150 may be located on the lower passivation film 140. The coating layer 159 may eliminate step differences caused by the driving portion 205 of each pixel region PA. For example, the upper surface of the coating layer 150 facing the substrate 10 may be a flat surface.

[0123] In one embodiment, the first transistor ET1 is electrically connected between the drain of the driving transistor DT and the first lower electrode 311 of the first light-emitting element 310. The second transistor ET2 is electrically connected between the drain of the driving transistor DT and the second lower electrode 321 of the second light-emitting element 320.

[0124] The first transistor ET1 may include a first light-emitting semiconductor pattern 211, a first light-emitting gate 213, a first light-emitting source 215, and a first light-emitting drain 217. The first transistor ET1 may have the same structure as the switching transistor ST and the driving transistor DT. For example, the first light-emitting semiconductor pattern 211 may be located between the element buffer film 110 and the gate insulating film 120, and the first light-emitting gate 213 may be located between the gate insulating film 120 and the interlayer insulating film 130. The first light-emitting source 215 and the first light-emitting drain 217 may be located between the interlayer insulating film 130 and the lower passivation film 140. The first light-emitting gate 213 may overlap with the channel region of the first light-emitting semiconductor pattern 211. The first light-emitting source 215 may be electrically connected to the source region of the first light-emitting semiconductor pattern 211. The first light-emitting drain 217 may be electrically connected to the drain region of the first light-emitting semiconductor pattern 211.

[0125] In an embodiment, the second transistor ET2 may include a second light-emitting semiconductor pattern 221, a second light-emitting gate 223, a second light-emitting source 225, and a second light-emitting drain 227. For example, the second light-emitting semiconductor pattern 221 may be located on the same layer as the first light-emitting semiconductor pattern 211, the second light-emitting gate 223 may be located on the same layer as the first light-emitting gate 213, and the second light-emitting source 225 and the second light-emitting drain 227 may be located on the same layer as the first light-emitting element 215 and the first light-emitting drain 217.

[0126] In one implementation, the first transistor ET1 may be formed simultaneously with the switching transistor ST and the driving transistor DT. The first transistor ET1 may also be formed simultaneously with the second transistor ET2.

[0127] The first light-emitting element 310 and the second light-emitting element 320 of each pixel region PA can be located on the coating layer 150 of the corresponding pixel region PA. For example, the first lower electrode 311 of the first light-emitting element 310 can be electrically connected to the first light-emitting drain 217 of the first transistor ET1 through the lower passivation film 140 and the coating layer 150, and the second lower electrode 321 of the second light-emitting element 320 can be electrically connected to the second light-emitting drain 227 of the second transistor ET2 through the lower passivation film 140 and the coating layer 150.

[0128] The second lower electrode 321 of each pixel region PA may be separated from the first lower electrode 311 of the corresponding pixel region PA. For example, a dam insulating film 160 may be disposed between the first lower electrode 311 and the second lower electrode 321 of each pixel region PA. The dam insulating film 160 may include an insulating material. For example, the dam insulating film 160 may include an organic insulating material. The dam insulating film 160 may include a material different from the material of the coating layer 150.

[0129] The second lower electrode 321 of each pixel region PA can be insulated from the first lower electrode 311 of the corresponding pixel region PA through the dam insulating film 160. For example, the dam insulating film 160 can cover the edges of the first lower electrode 311 and the second lower electrode 321 located in each pixel region PA. Therefore, in the display device, an image can be provided to the user through the first lens areas BWE, RWE, GWE of each pixel region PA provided with the first light-emitting element 310, or through the second lens areas BNE, RNE, GNE of each pixel region PA provided with the second light-emitting element 320.

[0130] The first light-emitting layer 312 and the first upper electrode 313 of the first light-emitting element 310 located in each pixel region PA can be stacked on a portion of the corresponding first lower electrode 311 exposed by the dam insulating film 160. The second light-emitting layer 322 and the second upper electrode 323 of the second light-emitting element 320 located in each pixel region PA can be stacked on a portion of the corresponding second lower electrode 321 exposed by the dam insulating film 160. For example, the dam insulating film 160 can distinguish the first light-emitting regions BE1, RE1, GE1 that emit light through the first light-emitting element 310 and the second light-emitting regions BE2, RE2, GE2 that emit light through the second light-emitting element 320 in each pixel region PA. The size of the second light-emitting regions BE2, RE2, GE2 that are distinguished in each pixel region PA can be smaller than the size of the first light-emitting regions BE1, RE1, GE1.

[0131] The second upper electrode 323 of each pixel region PA can be electrically connected to the first upper electrode 313 of the corresponding pixel region PA. For example, the voltage applied to the second upper electrode 323 of the second light-emitting element 320 located in each pixel region PA can be the same as the voltage applied to the first upper electrode 313 of the first light-emitting element 310 located in the corresponding pixel region PA. The second upper electrode 323 of each pixel region PA can be made of the same material as the first upper electrode 313 of the corresponding pixel region PA. For example, the second upper electrode 323 of each pixel region PA can be formed simultaneously with the first upper electrode 313 of the corresponding pixel region PA. The second upper electrode 323 of each pixel region PA can extend onto the insulating film 160 to directly contact the first upper electrode 313 of the corresponding pixel region PA. The brightness of the first lens regions BWE, RWE, GWE and the second lens regions BNE, RNE, GNE located in each pixel region PA can be controlled by the driving current generated in the corresponding pixel region PA.

[0132] The encapsulation component 800 may be located on the first light-emitting element 310 and the second light-emitting element 320 in each pixel region PA. The encapsulation component 800 can prevent the light-emitting elements 310 and 320 from being damaged by external moisture and impact. The encapsulation component 800 may have a multi-layer structure. For example, the encapsulation component 800 may include a first encapsulation layer 810, a second encapsulation layer 820, and a third encapsulation layer 830 stacked sequentially. The first encapsulation layer 810, the second encapsulation layer 820, and the third encapsulation layer 830 may include insulating materials. The second encapsulation layer 820 may include materials different from those of the first encapsulation layer 810 and the third encapsulation layer 830. For example, the first encapsulation layer 810 and the third encapsulation layer 830 may be inorganic encapsulation layers including inorganic insulating materials, and the second encapsulation layer 820 may be an organic encapsulation layer including organic insulating materials. Therefore, the light-emitting elements 310 and 320 of the display device can be effectively prevented from being damaged by external moisture and impact.

[0133] The first lens 510 and the second lens 520 may be located on the encapsulation member 800 of each pixel area PA.

[0134] The first lens 510 may be located on the first lens areas BWE, RWE, and GWE of each pixel area PA. For example, light generated by the first light-emitting element 310 of each pixel area PA may be emitted via the first lens 510 of the corresponding pixel area PA. The first lens 510 may have a shape in which light is not restricted in at least one direction. For example, the planar shape of the first lens 510 located in each pixel area PA may have a bar shape extending in a first direction.

[0135] In this scenario, the direction of light movement emitted from the first lens areas BWE, RWE, and GWE of the pixel area PA is not limited to the first direction. For example, content or images provided via the first lens areas BWE, RWE, and GWE of the pixel area PA can be shared with a person adjacent to the user in the first direction. The provision of content via the first lens areas BWE, RWE, and GWE is a mode of providing content within a first viewing angle range, which may be referred to as the first mode, wherein the first viewing angle range is wider than the second viewing angle range provided by the second lens areas BNE, RNE, and GNE.

[0136] The second lens 520 may be located on the second lens areas BNE, RNE, and GNE of each pixel area PA. Light generated by the second light-emitting element 320 of each pixel area PA may be emitted via the second lens 520 of the corresponding pixel area PA. The second lens 520 may restrict the direction of movement of light passing through a first direction and / or a second direction. For example, the planar shape of the second lens 520 located in the pixel area PA may be circular. In this case, the direction of movement of light emitted from the second lens areas BNE, RNE, and GNE of the pixel area PA may be limited to the first direction and the second direction. That is, the content provided by the second lens areas BNE, RNE, and GNE of the pixel area PA will not be shared by people adjacent to the user. The provision of content via the second lens areas BNE, RNE, and GNE is a mode of providing content with a second viewing angle range, which may be referred to as the second mode, wherein the second viewing angle range is narrower than the first viewing angle range provided by the first lens areas BWE, RWE, and GWE.

[0137] The first light-emitting areas BE1, RE1, and GE1 included in the first lens areas BWE, RWE, and GWE of each pixel region PA may have shapes corresponding to the first lenses 510 located on the first lens areas BWE, RWE, and GWE of the respective pixel region PA. For example, the planar shape of the first light-emitting areas BE1, RE1, and GE1 defined in the first lens areas BWE, RWE, and GWE of each pixel region PA may have a strip shape extending in a first direction. The first lenses 510 located on the first lens areas BWE, RWE, and GWE of the pixel region PA may have a larger size than the size of the first light-emitting areas BE1, RE1, and GE1 included in the first lens areas BWE, RWE, and GWE of the respective pixel region PA. Therefore, the efficiency of light emitted from the first light-emitting areas BE1, RE1, and GE1 of the pixel region PA can be improved.

[0138] The second light-emitting areas BE2, RE2, and GE2 included in the second lens areas BNE, RNE, and GNE of each pixel region PA can have shapes corresponding to the second lenses 520 located on the corresponding second lens areas BNE, RNE, and GNE of the pixel region PA. For example, the planar shape of the second light-emitting areas BE2, RE2, and GE2 included in the second lens areas BNE, RNE, and GNE of the pixel region PA can be circular. The second lenses 520 located on the second lens areas BNE, RNE, and GNE of the pixel region PA can have a larger size than the size of the second light-emitting areas BE2, RE2, and GE2 included in the corresponding second lens areas BNE, RNE, and GNE of the pixel region PA. For example, the planar shape of the second light-emitting areas BE2, RE2, and GE2 located on the second lens areas BNE, RNE, and GNE of each pixel region PA can be a circle concentric with the planar shape of the second lens 520 located on the corresponding second lens areas BNE, RNE, and GNE of the pixel region PA. In this case, the efficiency of light emitted from the second light-emitting areas BE2, RE2, and GE2 of the pixel region PA can be improved.

[0139] In an embodiment, the first lens region BWE, RWE, or GWE of the pixel region PA may include a first light-emitting region BE1, RE1, or GE1. The second lens region BNE, RNE, or GNE of the pixel region PA may include multiple second light-emitting regions BE2, RE2, or GE2.

[0140] In one embodiment, a first lens 510 may be disposed on the first lens areas BWE, RWE, and GWE of the pixel area PA. A plurality of second lenses 520 may be disposed on the second lens areas BNE, RNE, and GNE of the pixel area PA.

[0141] In one embodiment, the second light-emitting regions BE2, RE2, and GE2 included in the second lens regions BNE, RNE, and GNE of pixel region PA can be driven for each sub-pixel region. The second light-emitting regions included in a sub-pixel region (e.g., the second light-emitting region BE2, the second light-emitting region RE2, or the second light-emitting region GE2) can be driven simultaneously.

[0142] In this embodiment, a second lower electrode 321 may be located on the second lens regions BNE, RNE, and GNE of each pixel region PA. A dam insulating film 160 may be located between the second lower electrode 321 and the second light-emitting layer 322, between the second light-emitting regions BE2, RE2, and GE2. The dam insulating film 160 may be located between the second lower electrode 321 and the second light-emitting layer 322, between the second light-emitting regions BE2, RE2, and / or between the second light-emitting regions GE2. The second light-emitting layer 322 may be separated from the second lower electrode 321 by the dam insulating film 160 located between the second light-emitting regions BE2, RE2, and GE2 of the second lens regions BNE, RNE, and GNE. In this case, the luminous efficiency of the second light-emitting regions BE2, RE2, and GE2 can be improved.

[0143] In the implementation, the size of each of the second light-emitting areas BE2, RE2, and GE2 located in the second lens areas BNE, RNE, and GNE of pixel area PA can be specified as a specific value. For example, the sizes of the second light-emitting areas BE2, RE2, and GE2 located in the second lens areas BNE, RNE, and GNE of pixel area PA can be made to be identical to each other. The second light-emitting areas BE2, RE2, and GE2 located in the second lens areas BNE, RNE, and GNE of pixel area PA can have the same size as the sizes of the second light-emitting areas BE2, RE2, and GE2 included in the second lens areas BNE, RNE, and GNE of adjacent pixel areas PA.

[0144] In this implementation, the number of second light-emitting regions may differ for each of the sub-pixel regions RPA, GPA, and BPA. For example, the number of second light-emitting regions BE2 defined in the second lens region BNE of the blue sub-pixel region BPA may be greater than the number of second light-emitting regions RE2 defined in the second lens region RNE of the red sub-pixel region RPA. Similarly, the number of second light-emitting regions RE2 defined in the second lens region RNE of the red sub-pixel region RPA may be greater than the number of second light-emitting regions GE2 defined in the second lens region GNE of the green sub-pixel region GPA. In this case, by adjusting the number of second light-emitting regions BE2, RE2, and GE2 defined in the second lens regions BNE, RNE, and GNE of each pixel region PA, the efficiency deviation of the second light-emitting elements 320 located in the second lens regions BNE, RNE, and GNE of the pixel region can be compensated.

[0145] In an implementation, the sizes of the first light-emitting areas BE1, RE1, and GE1 may differ for each of the sub-pixel regions RPA, GPA, and BPA. For example, the first light-emitting area BE1 of the blue sub-pixel region BPA may have a different size than the first light-emitting area RE1 of the red sub-pixel region RPA, and may also have a different size than the first light-emitting area GE1 of the green sub-pixel region GPA. The size of the first light-emitting area BE1 of the blue sub-pixel region BPA may be larger than the size of the first light-emitting area RE1 of the red sub-pixel region RPA. The size of the first light-emitting area RE1 of the red sub-pixel region RPA may be larger than the size of the first light-emitting area GE1 of the green sub-pixel region GPA. Therefore, in a display device according to an embodiment of the present invention, the efficiency deviation of the first light-emitting elements 310 located on the first lens regions BWE, RWE, and GWE of each pixel region PA can be compensated by the size of the first light-emitting areas BE1, RE1, and GE1 defined in the first lens regions BWE, RWE, and GWE of each pixel region PA.

[0146] In an embodiment, a lens protective film 600 may be located on the first lens 510 and the second lens 520 of the pixel region PA. The lens protective film 600 may include an insulating material. For example, the lens protective film 600 may include an organic insulating material. The refractive index of the lens protective film 600 may be less than the refractive index of the first lens 510 and the second lens 520 located in each pixel region PA. Therefore, in the display device according to an embodiment of the present invention, due to the difference in refractive index with the lens protective film 600, light passing through the first lens 510 and the second lens 520 of each pixel region PA will not be reflected in the direction toward the substrate 10.

[0147] Figure 10 and 11 This is a conceptual diagram illustrating the gate driving circuit of a display device according to an embodiment of the present invention.

[0148] A gate driving circuit according to one embodiment of the present invention may include a scan driver and a light-emitting driver. The scan driver may generate scan signals (e.g., an nth scan signal Scan(n) and an (n-1)th scan signal Scan(n-1)). The light-emitting driver may generate light-emitting signals (e.g., a common light-emitting signal EM0, a first light-emitting signal EM1, and a second light-emitting signal EM2). The gate driving circuit may control the driving of a plurality of pixel circuits based on the provision of the first light-emitting signal EM1 and the second light-emitting signal EM2 to each of the plurality of pixel circuits.

[0149] Figure 10 A functional block diagram of a light-emitting driver included in a gate driving circuit according to an embodiment of the present invention is shown. (Refer to...) Figure 10The light-emitting driver 1000 can be implemented as a gate shift register including multiple stages (e.g., a first stage ST1, a second stage ST2, a third stage ST3, and a fourth stage ST4). According to an embodiment, the stages can be formed in a gate-in-panel (GIP) manner disposed inside the panel, but it is not limited thereto; the stages can be configured to be distinct from the panel.

[0150] Multiple stages ST1 to ST4 can output light-emitting signals (e.g., a first light-emitting signal EM1, a second light-emitting signal EM2, and a common light-emitting signal EM0) when their operation is activated sequentially. In an embodiment, the first stage ST1 may refer to the stage located on top of the light-emitting driver. After the first stage ST1, the second to fourth stages ST2 to ST4 can be sequentially arranged.

[0151] In this implementation, the operation of the first stage ST1 can be activated based on an external start signal VST, and the second stage ST2 and other stages (e.g., the third stage ST3 and the fourth stage ST4) can be activated based on any one of the emission signals EM1, EM2, and EM0 of the preceding stage. The emission signal of the preceding stage is an internal start signal and becomes a carry signal CRY. In this case, the term "preceding stage" can refer to the stage located above the reference stage that generates an emission signal whose phase is earlier than the phase of the emission signal output from the reference stage.

[0152] Reference Figure 10 In order to output the light emission signal, multiple stages ST1 to ST4 receive an external start signal EVST, a first clock signal ECLK1, and a second clock signal ECLK2 from a level shifter (not shown). The external start signal EVST, the first clock signal ECLK1, and the second clock signal ECLK2 can swing between a gate high voltage VGH and a gate low voltage VGL.

[0153] An external start signal EVST can be input to the first stage ST1, and a first clock signal ECLK1 and a second clock signal ECLK2 can be input to all stages ST1 through ST4. The first clock signal ECLK1 and the second clock signal ECLK2 can have opposite phases. According to an embodiment, for proper operation of stages connected in a cascade manner, the input positions of the first clock signal ECLK1 and the second clock signal ECLK2 can be set to be opposite in odd-numbered stages and even-numbered stages. For example, when the first clock signal ECLK1 is input to the first terminal and the second clock signal ECLK2 is input to the second terminal at an odd-numbered stage, the first clock signal ECLK1 can be input to the second terminal and the second clock signal ECLK2 can be input to the first terminal at an even-numbered stage.

[0154] In this implementation, each of stages ST1 through ST4 can activate the operation of node Q based on a start signal applied to the start terminal in each frame. In this case, node activation means that a low gate voltage VGL or a corresponding voltage is applied to the node. Node inactivation means that a high gate voltage VGH or a corresponding voltage is applied to the node. The low gate voltage VGL can refer to the gate on-state voltage, and the high gate voltage VGH can refer to the gate off-state voltage.

[0155] According to an embodiment, as shown in the figure, each of stages ST1 to ST4 may be provided with a gate high potential voltage VGH and a gate low potential voltage VGL from an external power supply (not shown). The gate high potential voltage VGH may be preset to a value between 20V and 30V, and the gate low potential voltage VGL may be preset to a value between -10V and 0V, but the invention is not limited thereto.

[0156] In one embodiment, the gate low potential voltage VGL can be provided via a first voltage line providing a first value of voltage. According to one embodiment, the first voltage line may be referred to as a low potential line. The gate high potential voltage VGH can be provided via a second voltage line providing a second value of voltage higher than the first value. According to one embodiment, the second voltage line may be referred to as a high potential line.

[0157] Figure 11 This is a simplified circuit diagram illustrating the gate drive circuit according to an embodiment of the present invention. More specifically, Figure 11 This diagram illustrates a stage (e.g., in a light-emitting driver within a gate drive circuit) that is included. Figure 10 The circuit diagram of the first stage ST1).

[0158] Reference Figure 11 The gate drive circuit may include a node controller 1101, a first mode controller 1111, and a second mode controller 1112. The first mode controller 1111 may include a first pull-down transistor PD1, a first pull-up transistor PU1, and mode control transistors M11 and M12. The second mode controller 1112 may include a second pull-down transistor PD2, a second pull-up transistor PU2, and mode control transistors M21 and M22.

[0159] In some implementations, the internal circuitry of node controller 1101 may be configured to include a plurality of transistors. The internal circuitry of node controller 1101 may include Q nodes, QB nodes, and set nodes (or start nodes). In some cases, the internal circuitry of node controller 1101 may further include reset nodes for inputting reset signals, input nodes for inputting various voltages (e.g., drive voltages), etc.

[0160] In one implementation, node controller 1101 may receive a gate start signal VST indicating the start of gate driving for a corresponding gate driver. The node to which the gate start signal VST is applied may be referred to as a set node. In this case, depending on the number of phases of the clock signal, the gate start signal VST may include an external start signal (e.g., Figure 10 The external start signal (EVST) or a signal output from a component of the gate drive circuit (e.g., in the preceding stage) before the current gate line (e.g., a carry signal). Figure 10 The carry signal (CRY).

[0161] In this implementation, the node controller 1101 may receive a first clock signal ECLK1 and a second clock signal ECLK2.

[0162] In one implementation, the Q node of the node controller 1101 may be electrically connected to the gate node of a pull-down transistor (e.g., a first pull-down transistor PD1 and a second pull-down transistor PD2). The QB node of the node controller 1101 may be electrically connected to the gate node of a pull-up transistor (e.g., a first pull-up transistor PU1 and a second pull-up transistor PU2). The Q node and QB node may be repeatedly charged and discharged.

[0163] In one implementation, the (1-1) mode control transistor M11 may be disposed between the Q node and the first pull-down transistor PD1. For example, the first electrode of the (1-1) mode control transistor M11 may be connected to the Q node, and the second electrode of the (1-1) mode control transistor M11 may be connected to the gate of the first pull-down transistor PD1. The gate of the (1-1) mode control transistor M11 may be connected to the first mode signal line 1110, wherein a first mode signal MOD1 that controls the operation to the first mode is provided to the first mode signal line 1110. The (1-1) mode control transistor M11 may be turned on or off based on the provision of the first mode signal MOD1.

[0164] The (2-1) mode control transistor M21 can be disposed between the Q node and the second pull-down transistor PD2. For example, the first electrode of the (2-1) mode control transistor M21 can be connected to the Q node, and the second electrode of the (2-1) mode control transistor M21 can be connected to the gate of the second pull-down transistor PD2. The gate of the (2-1) mode control transistor M21 can be connected to the second mode signal line 1120, wherein a second mode signal MOD2 that controls the operation to the second mode is provided to the second mode signal line 1120. The (2-1) mode control transistor M21 can be turned on or off based on the provision of the second mode signal MOD2.

[0165] The mode control transistor M12 (1-2) can be disposed between the QB node and the first pull-up transistor PU1. For example, the first electrode of the mode control transistor M12 (1-2) can be connected to the QB node, and the second electrode of the mode control transistor M12 (1-2) can be connected to the gate of the first pull-up transistor PU1. The gate of the mode control transistor M12 (1-2) can be connected to the first mode signal line 1110, wherein a first mode signal MOD1 that controls the operation to the first mode is provided to the first mode signal line 1110. The mode control transistor M12 (1-2) can be turned on or off based on the provision of the first mode signal MOD1.

[0166] The (2-2) mode control transistor M22 can be disposed between the QB node and the second pull-up transistor PU2. For example, the first electrode of the (2-2) mode control transistor M22 can be connected to the QB node, and the second electrode of the (2-2) mode control transistor M22 can be connected to the gate of the second pull-up transistor PU2. The gate of the (2-2) mode control transistor M22 can be connected to the second mode signal line 1120, wherein a second mode signal MOD2 that controls the operation to the second mode is provided to the second mode signal line 1120. The (2-2) mode control transistor M22 can be turned on or off based on the provision of the second mode signal MOD2.

[0167] In this case, the first mode may refer to a first light-emitting element (e.g., a light-emitting element that emits light based on the provision of a first light-emitting signal EM1). Figure 5 Or the mode in which the viewing angle of the first light-emitting element ED1 (or 6) is greater than or equal to the first value. (Refer to...) Figure 8 The described first lens 510 may be disposed on a first light-emitting element (which emits light in a first mode) to provide light with a wider viewing angle than the second mode, which will be described later. The second mode may refer to a second light-emitting element (e.g., emitting light based on the provision of the first light-emitting signal EM1) that emits light. Figure 5 Or the second light-emitting element ED2 of 6 has a viewing angle smaller than the first value. (Refer to...) Figure 9 The described second lens 520 may be disposed on the second light-emitting element (which emits light in the second mode) to provide light with a narrower angle of view than the second mode.

[0168] In this implementation, the first pull-down transistor PD1 and the second pull-down transistor PD2 may be connected to a first voltage line (or a low-potential line). For example, the first electrode of each of the first pull-down transistor PD1 and the second pull-down transistor PD2 may be connected to the first voltage line (or a low-potential line). The first pull-up transistor PU1 and the second pull-up transistor PU2 may be connected to a second voltage line (or a high-potential line). For example, the first electrode of each of the first pull-up transistor PU1 and the second pull-up transistor PU2 may be connected to the second voltage line (or a high-potential line).

[0169] According to the embodiment, when the first pull-down transistor PD1 is turned on, a gate low potential voltage VGL can be provided as the first light-emitting signal EM1. When the first pull-up transistor PU1 is turned on, a gate high potential voltage VGH can be provided as the first light-emitting signal EM1. When the second pull-down transistor PD2 is turned on, a gate low potential voltage VGL can be provided as the second light-emitting signal EM2. When the second pull-up transistor PU2 is turned on, a gate high potential voltage VGH can be provided as the second light-emitting signal EM2. In this case, the gate high potential voltage VGH can be a voltage with a higher voltage value than the gate low potential voltage VGL. The values ​​of each of the gate high potential voltage VGH and the gate low potential voltage VGL can be predetermined.

[0170] According to the implementation method, at least one of the mode control transistors M11, M12, M21, and M22 may be omitted. (See reference...) Figure 12 and / or Figure 13 A more detailed example related to this is described below. See also... Figure 14 and / or Figure 15 Description as follows Figure 11 A more detailed example is shown, including mode control transistors M11, M12, M21, and M22.

[0171] In one embodiment, the transistors included in the gate drive circuit may be p-type. In this case, the transistors are turned on when a low-level voltage is applied to each transistor, and are turned off when a high-level voltage is applied to each transistor. Hereinafter, all transistors included in the gate drive circuit described in this invention may be p-type, but the embodiment is not limited thereto, and n-type transistors may also be used depending on design changes.

[0172] Furthermore, the terms "first electrode" and "second electrode" are used to distinguish the electrodes of a transistor included in a gate drive circuit. For each transistor, the first electrode and / or the second electrode may be distinguished to be interpreted as a source or a drain, but the invention is not limited thereto.

The second transistor T2 can receive the gate start signal VST in response to the conduction of the first transistor T1. The second transistor T2 can be turned on or off based on the provision of the first clock signal ECLK1.

[0178] The first electrode of the third transistor T3 can be connected to the second electrode of the second transistor T2.

The gate of the eighth transistor T8 can be connected to the second electrode of the tenth transistor T10. The eighth transistor T8 can receive the second clock signal ECLK2 in response to the conduction of the tenth transistor T10.

The second electrode of the tenth transistor T10 may be connected to the third transistor T3, the fourth transistor T4, the eighth transistor T8, and the node control capacitor CQ'. According to an embodiment, the tenth transistor T10 may include dual gates, but is not limited thereto.

[0184] In this embodiment, the node connected to the second electrode of the first transistor T1, the first electrode of the second transistor T2, the gate of the fifth transistor T5, and the gate of the tenth transistor T10 can be referred to as a Q node (or the first node). The Q node can be connected to the first mode controller 1211, the second mode controller 1212, and the common signal controller 1213.
