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

[0028] The present specification will now be described with reference to the accompanying drawings, in which:

[0029] FIG. 1 is a diagram illustrating a display device according to an embodiment of the present disclosure.

[0030] The display device 100 may be disposed in at least a part of a dashboard of a vehicle. The dashboard of a vehicle includes a configuration disposed in front of a front seat (e.g., a driver's seat, a passenger seat) of the vehicle. For example, an input configuration for operating various functions (e.g., an air conditioner, an audio system, a navigation system) inside the vehicle may be disposed on the dashboard of the vehicle.

[0031] In an embodiment, the display device 100 is disposed on a dashboard of a vehicle and can operate as an input unit for operating at least some of the various functions of the vehicle. The display device 100 can provide various information related to the vehicle, such as vehicle operation information (e.g., the current speed of the vehicle, the remaining fuel, and the mileage) and information about vehicle parts (e.g., the degree of damage to the vehicle tires).

[0032] In an embodiment, the display device 100 may be disposed across the driver's seat and the passenger seat disposed in the front seats of the vehicle. The user of the display device 100 may include the driver of the vehicle and the passenger seat. Any of the driver and passengers of the vehicle may use the display device 100.

[0033] In an embodiment, the display device 100 shown in FIG. 1 may show only a part of the display device 100. The display device 100 shown in FIG. 1 shows a display panel among various components included in the display device 100. Specifically, for example, the display device 100 shown in FIG. 1 shows at least a part of a display area and a non-display area of ​​the display panel. Among the components of the display device 100, components other than those shown in FIG. 1 may be implemented inside (or at least in part) the vehicle.

[0034] In an embodiment, the display device 100 shown in Fig. 1 is divided into a cluster region, a center information display (CID) region, and a co-driver display (CDD) region, and each region may be implemented as a separate display device, or may be implemented as a single display device extending from the cluster region to the CDD. Although Fig. 1 shows a single display device 100 implemented as an extension, the present invention is not limited thereto, and the cluster region, the CID region, and the CDD region may be configured to cover the cluster region, the CID region, and the CDD region as one or more display devices.

[0035] On the other hand, the viewing angle of a part of the display device 100 can be adjusted so that the image displayed on the part of the CID or the CDD does not attract the driver's gaze, thereby restricting the driver of the vehicle from viewing the image.

[0036] In this manner, a certain area of ​​the display device 100 mounted in the vehicle can have the function of adjusting the viewing angle to limit the driver's viewing.

[0037] 2 is a cross-sectional view of a display device according to an embodiment of the present disclosure, and illustrates a pixel configuration for adjusting a viewing angle in the display device 100 described above.

[0038] As shown in FIG. 2, a display device 100 according to an embodiment of the present specification may include a substrate 110, a plurality of first light-emitting elements De1, a plurality of second light-emitting elements De2, a sealing layer 190, a light-shielding pattern 210, an optical gap layer 220, a lens layer 230, a planarization layer 240, and a polarizing layer 250.

[0039] A plurality of subpixels SP1, SP2, and SP3 are defined on the substrate 110. For example, a first subpixel SP1, a second subpixel SP2, and a third subpixel SP3 are defined on the substrate 110. The first subpixel SP1, the second subpixel SP2, and the third subpixel SP3 each have a first light-emitting portion EA1 and a second light-emitting portion EA2.

[0040] The first light emitting section EA1 includes a first light emitting element De1, and the second light emitting section EA2 includes a second light emitting element De2.

[0041] The first subpixel SP1, the second subpixel SP2, and the third subpixel SP3 may be a red subpixel, a green subpixel, and a blue subpixel, respectively, so that the first light-emitting element De1 and the second light-emitting element De2 of the first subpixel SP1 can emit red light, the first light-emitting element De1 and the second light-emitting element De2 of the second subpixel SP2 can emit green light, and the first light-emitting element De1 and the second light-emitting element De2 of the third subpixel SP3 can emit blue light.

[0042] An encapsulation layer 190 having a flat upper surface is provided on the first light emitting element De1 and the second light emitting element De2 to protect the first light emitting element De1 and the second light emitting element De2 from moisture and oxygen.

[0043] A light-shielding pattern 210 is provided on the encapsulation layer 190. The light-shielding pattern 210 is formed corresponding to between adjacent first to third sub-pixels SP1, SP2, and SP3 or between the first light emitting portion EA1 and the second light emitting portion EA2.

[0044] The light-shielding pattern 210 is a black matrix and may be made of black resin or chromium oxide. In contrast, the light-shielding pattern 210 is a touch electrode and may be made of metal. Here, the touch electrode includes a number of crossed transmitting electrodes and a number of receiving electrodes, and a touch can be sensed from a change in capacitance between the number of transmitting electrodes and the number of receiving electrodes.

[0045] An optical gap layer 220 is provided on the light-shielding pattern 210. The optical gap layer 220 secures an optical gap between the first and second light-emitting elements De1 and De2 and the lenses 232 and 234 of the lens layer 230, and refracts the light from the first and second light-emitting elements De1 and De2 in a specific direction by the lenses 232 and 234, thereby improving the efficiency of the lenses 232 and 234. The optical gap layer 220 may have a thickness of several to several tens of μm and may be made of an organic insulating material.

[0046] As an example, the optical gap layer 220 may be made of, but is not limited to, photoacryl, benzocyclobutene (BCB), polyimide (PI), or polyamide (PA).

[0047] The lens layer 230 is provided on the optical gap layer 220. The lens layer 230 includes a first lens 232 and a second lens 234. The first lens 232 is disposed in the first light emitting unit EA1 and refracts light from the first light emitting element De1 in a specific direction. The second lens 234 is disposed in the second light emitting unit EA2 and refracts light from the second light emitting element De2 in a specific direction. Each of the first lens 232 and the second lens 234 may partially overlap with the light blocking pattern 210.

[0048] The first lens 232 is a half-spherical lens, and the second lens 234 is a half-cylindrical lens. Therefore, the first light L1 emitted from the first light-emitting element De1 of each of the sub-pixels SP1, SP2, and SP3 is refracted at a specific angle by the first lens 232 and output. And the second light L2 emitted from the second light-emitting element De2 of each of the sub-pixels SP1, SP2, and SP3 is refracted at a specific angle by the second lens 234 and output. Therefore, the viewing angle of each of the sub-pixels SP1, SP2, and SP3 can be limited.

[0049] A planarization layer 240 is provided on the lens layer 230 to protect the first lens 232 and the second lens 234. The planarization layer 240 is made of an organic insulating material and has a flat upper surface. The refractive index of the planarization layer 240 is smaller than the refractive index of the first lens 232 and the second lens 234.

[0050] As an example, the planarization layer 240 may be made of, but is not limited to, photoacryl, benzocyclobutene (BCB), polyimide (PI), or polyamide (PA).

[0051] A polarizing layer 250 is provided on the planarization layer 240. The polarizing layer 250 may include a linear polarizing layer and a retardation layer, and serves to prevent the external light from being reflected by the display device 100 and then emitted to the outside by converting the polarization state of the external light incident on the display device 100.

[0052] A light emitting region of a display device according to an embodiment of the present specification will be described with reference to FIG.

[0053] FIG. 3 is a cross-sectional view of a light-emitting region of a display device according to an embodiment of the present disclosure.

[0054] As shown in FIG. 3, a display device 100 according to an embodiment of the present disclosure includes a substrate 110, a plurality of transistors T1 and T2, a plurality of light-emitting elements De1 and De2, and an encapsulation layer 190. The display device 100 includes a substrate 110, a plurality of transistors T1 and T2, a plurality of light-emitting elements De1 and De2, and an encapsulation layer 190.

[0055] Specifically, each of the sub-pixels SP1, SP2, and SP3 on the substrate 110 includes a first light-emitting portion EA1 and a second light-emitting portion EA2. The substrate 110 may be a glass substrate or a plastic substrate. For example, polyimide (PI) may be used as the plastic substrate, but is not limited thereto.

[0056] A buffer layer 120 is formed on the substrate 110. The buffer layer 120 is located on substantially the entire surface of the substrate 110. The buffer layer 120 prevents moisture and foreign matter from entering the transistors T1 and T2 from the substrate 110. The buffer layer 120 is made of silicon oxide (SiO 2 ) or silicon nitride (SiN x ) and can be a single layer or multiple layers.

[0057] A patterned first semiconductor layer 122 and a patterned second semiconductor layer 124 are formed in the first light emitting portion EA1 and the second light emitting portion EA2 on the buffer layer 120. The first semiconductor layer 122 and the second semiconductor layer 124 may be made of an oxide semiconductor material or polycrystalline silicon, independently.

[0058] When the first semiconductor layer 122 and the second semiconductor layer 124 are made of an oxide semiconductor material, a shielding pattern may be further formed below them. The shielding pattern blocks light incident on the first semiconductor layer 122 and the second semiconductor layer 124 to prevent the first semiconductor layer 122 and the second semiconductor layer 124 from being deteriorated by light.

[0059] On the other hand, when the first and second semiconductor layers 122 and 124 are made of polycrystalline silicon, both side edges of each of the first and second semiconductor layers 122 and 124 may be doped with impurities.

[0060] A gate insulating layer 130 made of an insulating material is disposed on the first semiconductor layer 122 and the second semiconductor layer 124. Although the gate insulating layer 130 is shown in FIG. 2 as being formed substantially on the front surface of the substrate 110, as another example, the gate insulating layer 130 may be patterned to have the same shape as the first gate electrode 132 and the second gate electrode 134.

[0061] The gate insulating layer 130 is made of silicon oxide (SiO 2 ) or silicon nitride (SiN x When the first semiconductor layer 122 and the second semiconductor layer 124 are made of an oxide semiconductor material, the gate insulating layer 130 may be made of an inorganic insulating material such as silicon oxide (SiO 2 In contrast, if the first semiconductor layer 122 and the second semiconductor layer 124 are made of polycrystalline silicon, the gate insulating layer 130 may be made of silicon oxide (SiO 2 ) or silicon nitride (SiN x )

[0062] A first gate electrode 132 and a second gate electrode 134 made of a conductive material such as a metal are formed on the gate insulating layer 130 to correspond to the first semiconductor layer 122 and the second semiconductor layer 124, respectively. In addition, a gate wiring (not shown) may be formed on the gate insulating layer 130. The gate wiring may extend in one direction.

[0063] An interlayer insulating layer 140 made of an insulating material is formed on the first gate electrode 132 and the second gate electrode 134 substantially on the front surface of the substrate 110. The interlayer insulating layer 140 is made of silicon oxide (SiO 2 ) or silicon nitride (SiN x The insulating layer 14 may be made of an inorganic insulating material such as SiO 2 or may be made of an organic insulating material such as photoacryl or benzocyclobutene.

[0064] The interlayer insulating layer 140 has contact holes exposing both upper surfaces of the first semiconductor layer 122 and the second semiconductor layer 124. The contact holes may also be formed in the gate insulating layer 130. A first source electrode 142 and a first drain electrode 144, and a second source electrode 146 and a second drain electrode 148 are respectively formed on the first light emitting unit EA1 and the second light emitting unit EA2 on the interlayer insulating layer 140 and made of a conductive material such as a metal. In addition, a data line (not shown) and a power line (not shown) may be formed on the interlayer insulating layer 140 to extend in a direction perpendicular to one direction.

[0065] The first source electrode 142 and the first drain electrode 144 contact both sides of the first semiconductor layer 122 through contact holes in the interlayer insulating layer 140, and the second source electrode 146 and the second drain electrode 148 contact both sides of the second semiconductor layer 124 through contact holes in the interlayer insulating layer 140. Although not shown, the data lines extend in a direction perpendicular to one direction and cross the gate lines to define pixel regions corresponding to each subpixel, and power lines for supplying a high potential voltage are located apart from the data lines.

[0066] Meanwhile, the first semiconductor layer 122, the first gate electrode 132, the first source electrode 142 and the first drain electrode 144 form a first transistor T1, and the second semiconductor layer 124, the second gate electrode 134, the second source electrode 146 and the second drain electrode 148 form a second transistor T2.

[0067] One or more transistors having the same structure as the first transistor T1 and the second transistor T2 may be further formed on the substrate 110 of each sub-pixel, but is not limited thereto.

[0068] A protective layer 150 made of an insulating material is formed on the first source electrode 142, the first drain electrode 144, the second source electrode 146, and the second drain electrode 148 substantially on the front surface of the substrate 110. The protective layer 150 may be made of an organic insulating material such as photoacryl or benzocyclobutene. The protective layer 150 has a flat upper surface.

[0069] Meanwhile, silicon oxide (SiO ) is formed under the protective layer 150, i.e., between the first transistor T1 and the second transistor T2 and the protective layer 150. 2 ) or silicon nitride (SiN x ) may further be formed as an insulating film made of an inorganic insulating material.

[0070] The protective layer 150 has a first drain contact hole 150a and a second drain contact hole 150b that expose the first drain electrode 144 and the second drain electrode 148, respectively.

[0071] A first anode electrode 162 and a second anode electrode 164 are formed on the protective layer 150 using a conductive material having a relatively high work function. The first anode electrode 162 is located in the first light emitting portion EA1 and contacts the first drain electrode 144 through the first drain contact hole 150a. The second anode electrode 164 is located in the second light emitting portion EA2 and contacts the second drain electrode 148 through the second drain contact hole 150b.

[0072] As an example, each of the first anode electrode 162 and the second anode electrode 164 may be formed of a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO), but is not limited thereto.

[0073] Meanwhile, the display device 100 according to an embodiment of the present specification is a top emission type in which light from the light emitting devices De1 and De2 is output in a direction opposite to the substrate 110, and therefore each of the first anode electrode 162 and the second anode electrode 164 may further include a reflective electrode or reflective layer made of a metal material with high reflectivity under the transparent conductive material. For example, the reflective electrode or reflective layer may be made of an aluminum-palladium-copper (APC) alloy, silver (Ag), or aluminum (Al). Here, each of the first anode electrode 162 and the second anode electrode 164 may have a triple layer structure of ITO / APC / ITO, ITO / Ag / ITO, or ITO / Al / ITO, but is not limited thereto.

[0074] A bank layer 165 made of an insulating material is formed on the first anode electrode 162 and the second anode electrode 164. For example, the bank layer 165 may be made of, but is not limited to, a polyimide resin, an acryl resin, or a benzocyclobutene resin. In the present invention, the bank layer 165 has a single layer structure, but the bank layer 165 may have a double layer structure. That is, the bank layer 165 may have a double layer structure including a lower hydrophilic bank layer and an upper hydrophobic bank layer.

[0075] The bank layer 165 overlaps the edges of the first anode electrode 162 and the second anode electrode 164 and covers the edges of the first anode electrode 162 and the second anode electrode 164. The bank layer 165 has a first opening 165a and a second opening 165b that expose the first anode electrode 162 and the second anode electrode 164.

[0076] Meanwhile, the bank layer 165 included in at least one of the first subpixel SP1, the second subpixel SP2, and the third subpixel SP3 may further include a third opening that further exposes at least one of the first anode electrode 162 and the second anode electrode 164. A more detailed description of the bank layer including the third opening will be given later.

[0077] A light emitting unit 170 is formed on the first anode electrode 162 and the second anode electrode 164 exposed through the first opening 165a and the second opening 165b of the bank layer 165. The light emitting unit 170 may include an organic layer 172 and a light emitting layer 174 located between the first anode electrode 162 and the second anode electrode 164.

[0078] The organic layer 172 is a functional layer disposed to improve the light emitting efficiency of the light emitting layer 174. For example, the organic layer 172 may include at least one of a hole injection layer (HIL) for facilitating hole injection, a hole transport layer (HTL) for facilitating hole transport, an electron injection layer (EIL) for facilitating electron injection from the cathode electrode 180, and an electron transport layer (ETL) for facilitating electron transport. The organic layer 172 may be formed as one layer in each of the subpixels SP1, SP2, and SP3. Alternatively, the organic layer 172 may be formed as a single layer throughout each of the subpixels SP1, SP2, and SP3. That is, the organic layers 172 of the subpixels SP1, SP2, and SP3 may be a common layer that is connected to each other and integrated. 2, the organic layer 172 is shown as being disposed below the light-emitting layer 174, but depending on the type of organic layer 172, it may be disposed above the light-emitting layer 174. For example, a hole injection layer (HIL) and a hole transport layer (HTL) may be disposed below the light-emitting layer 174, and an electron injection layer (EIL) and an electron transport layer (ETL) may be disposed above the light-emitting layer 174.

[0079] The light emitting layer 174 may be made of any one of red, green and blue light emitting materials, but is not limited thereto. Such light emitting materials may be organic light emitting materials such as phosphorescent compounds or fluorescent compounds. However, the present invention is not limited thereto, and inorganic light emitting materials such as quantum dots may also be used.

[0080] The light emitting layer 174 on the upper part of the first anode electrode 162 and the light emitting layer 174 on the upper part of the second anode electrode 164 are connected to each other to form an integrated structure. However, the present invention is not limited thereto, and the light emitting layer 174 on the upper part of the first anode electrode 162 and the light emitting layer 174 on the upper part of the second anode electrode 164 may be separated from each other.

[0081] The light emitting layer 174 may be formed by an evaporation process. Here, a fine metal mask (FMM) may be used to pattern the light emitting layer 174 for each sub-pixel. Alternatively, the light emitting layer 174 may be formed by a solution process. In this case, the light emitting layer 174 may be provided only in the first opening 165a and the second opening 165b, and the height of the light emitting layer 174 around the bank layer 165 may increase as it approaches the bank layer 165.

[0082] A cathode electrode 180 made of a conductive material having a relatively low work function is formed on the upper surface of the light emitting unit 170 substantially on the front surface of the substrate 110. The cathode electrode 180 may be made of aluminum, magnesium, silver, or an alloy thereof. The cathode electrode 180 has a relatively thin thickness so that light from the light emitting unit 170 can be transmitted through it. The cathode electrode 180 may be made of a transparent conductive material such as, but is not limited to, indium-gallium-oxide (IGO).

[0083] The first anode electrode 162, the light emitting unit 170 and the cathode electrode 180 of the first light emitting portion EA1 form a first light emitting element De1, and the second anode electrode 164, the light emitting unit 170 and the cathode electrode 180 of the second light emitting portion EA2 form a second light emitting element De2.

[0084] The display device 100 according to an embodiment of the present invention may be a top emission type in which light from the light emitting units 170 of the first light emitting device De1 and the second light emitting device De2 is output in a direction opposite to the substrate 110, i.e., to the outside through the cathode electrode 180. Such a top emission type may have a wider light emitting area than a bottom emission type of the same area, thereby improving brightness and reducing power consumption.

[0085] An encapsulation layer 190 is formed on substantially the entire surface of the substrate 110 above the cathode electrode 180. The encapsulation layer 190 prevents moisture or oxygen from entering the first light emitting element De1 and the second light emitting element De2 from the outside. The encapsulation layer 190 may be formed as a single layer or multiple layers. For example, the encapsulation layer 190 may have a stacked structure of a first inorganic layer 192, an organic layer 194, and a second inorganic layer 196. Here, the organic layer 194 may be a film that blocks foreign matter generated during the manufacturing process.

[0086] In this manner, in a display device according to one embodiment of the present specification, each sub-pixel SP1, SP2, SP3 has a first light-emitting portion EA1 and a second light-emitting portion EA2, and is provided with a hemispherical first lens 232 on the upper portion of the first light-emitting portion EA1 and a semi-cylindrical second lens 234 on the upper portion of the second light-emitting portion EA2, thereby limiting the viewing angle.

[0087] 4 is a driving circuit diagram of a pixel according to an embodiment of the present specification. Referring to FIG. 4, the pixel circuit PC may include nine transistors and one capacitor.

[0088] The pixel circuit PC may include a first transistor T1, a second transistor T2, a third transistor T3, a 4-1 transistor T41, a 4-2 transistor T42, a fifth transistor T5, a sixth transistor T6, a seventh transistor T7, a driving transistor DT, and a capacitor Cst.

[0089] At least some of the nine transistors included in the pixel circuit PC may be n-type transistors or p-type transistors. In the case of p-type transistors, the low level voltage of each driving signal may mean a voltage that turns on the TFT, and the high level voltage of each driving signal may mean a voltage that turns off the TFT.

[0090] Here, the low level voltage may correspond to a predetermined voltage lower than the high level. For example, the low level voltage may include a voltage corresponding to a range of -8V to -12V. The high level voltage may correspond to a predetermined voltage higher than the low level voltage. For example, the high level voltage may include a voltage corresponding to a range of 12V to 16V. Depending on the embodiment, the low level voltage may be referred to as a first voltage, and the high level voltage may be referred to as a second voltage. In such a case, the first voltage may be lower than the second voltage. However, the above-mentioned ranges of the low level voltage and the high level voltage are merely examples, and are not limited thereto.

[0091] The first electrode or the second electrode of a transistor described below may refer to a source electrode or a drain electrode. However, the terms first electrode and second electrode are merely terms for distinguishing between the electrodes and do not limit what each electrode corresponds to. In addition, the first electrode of each electrode may not refer to the same electrode. For example, the first electrode of the first transistor T1 may refer to the source electrode of the first transistor T1, and the first electrode of the sixth transistor T6 may refer to the drain electrode of the sixth transistor T6.

[0092] In an embodiment, the driving transistor DT may be connected to a first transistor T1 connected to the first light emitting element De1 and a second transistor T2 connected to the second light emitting element De2. For example, the second electrode of the driving transistor DT may be connected to the first transistor T1 and the second transistor T2.

[0093] In an embodiment, the driving transistor DT may be connected to a first power supply line L17 that provides a high potential power supply voltage ELVDD. For example, a first electrode of the driving transistor DT may be connected to the first power supply line L17. When the driving transistor DT is turned on, the high potential power supply voltage ELVDD provided via the first power supply line L17 may be transferred from the first electrode to the second electrode of the driving transistor DT.

[0094] In the embodiment, the first transistor T1 may be connected to at least one of the first light emitting element De1, the second transistor T2, the (4-1)th transistor T41, and the seventh transistor T7.

A second electrode of the first transistor T1 may be connected to at least one of the first light emitting element De1 and the 4-1st transistor T41. A gate electrode of the first transistor T1 may be connected to a first control line L10. The first transistor T1 may be turned on or off by a first control signal P(k) provided via the first control line L10. When the first transistor T1 is turned on, a voltage via the driving transistor DT and the seventh transistor T7 may be input to the first light emitting element De1 (e.g., an anode electrode of the first light emitting element De1).

[0096] Here, the first control signal P(k) may include a kth first control signal supplied to the kth column corresponding to the pixel circuit PC being arranged in the kth column (k is a positive integer). The first control signal P(k) is provided by a mode control unit (or a mode control circuit) and may control the driving (or emission) of the first light emitting element De1 in which the first lens is arranged.

[0097] In the embodiment, the second transistor T2 may be connected to at least one of the second light emitting element De2, the first transistor T1, the (4-2)th transistor T42, and the seventh transistor T7.

A second electrode of the second transistor T2 may be connected to at least one of the 4-2 transistor T42 and the second light-emitting element De2. And, the seventh transistor T7 may be connected to the driving transistor DT and the fifth transistor T5. A gate electrode of the second transistor T2 may be connected to the second control line L20. The second transistor T2 may be turned on or off by a second control signal S(k) provided via the second control line L20. When the second transistor T2 is turned on, a voltage via the driving transistor DT and the seventh transistor T7 may be input to the second light-emitting element De2 (e.g., an anode electrode of the second light-emitting element De2).

[0099] Here, the second control signal S(k) may include a kth second control signal supplied to the kth column corresponding to the pixel circuit PC being arranged in the kth column (k is a positive integer). The second control signal S(k) is provided by a mode control unit (or a mode control circuit) and may control the driving (or emission) of the second light-emitting element De2 in which the second lens is arranged.

[0100] In the embodiment, a first lens may be disposed on the first light-emitting element De1. The first lens may allow the viewing angle of the area where the first light-emitting element De1 is disposed to correspond to a first value. For example, the viewing angle of the area where the first light-emitting element De1 is disposed may be equal to or less than the first value. A second lens may be disposed on the second light-emitting element De2. The second lens may allow the viewing angle of the area where the second light-emitting element De2 is disposed to correspond to a second value. The second value may be greater than the first value. For example, the viewing angle of the area where the second light-emitting element De2 is disposed may be equal to or greater than the second value.

[0101] In the embodiment, the region where the first light emitting element De1 of the pixel circuit PC is arranged may have a first viewing angle value so as to provide light to a range corresponding to the passenger seat, and the region where the second light emitting element De2 is arranged may have a second viewing angle value so as to provide light to a range corresponding to the passenger seat and the driver's seat beside the passenger seat.

[0102] In an embodiment, the third transistor T3 may be connected to at least one of the 4-1st transistor T41, the 4-2nd transistor T42, the sixth transistor T6, and the capacitor Cst.

[0103] For example, a first electrode of the third transistor T3 may be connected to the sixth transistor T6 and the capacitor Cst. A second electrode of the third transistor T3 may be connected to the 4-1 transistor T41 and the 4-2 transistor T42. A gate electrode of the third transistor T3 may be connected to a light emission signal wiring L15 that supplies a light emission signal EM(n). The light emission signal EM(n) may correspond to an n-th light emission signal EM(n) supplied to the n-th row, in response to the pixel circuit PC being arranged in the n-th pixel row (n is a positive integer). The third transistor T3 may be turned on or off by the light emission signal EM(n). A second electrode of the third transistor T3 may be connected to a reference voltage wiring L11 that supplies a reference voltage Vref, for example, a second power supply wiring.

[0104] In the embodiment, the 4-1st transistor T41 may be connected to at least one of the first transistor T1, the third transistor T3, and the first light emitting element De1.

[0105] For example, a first electrode of the 4-1 transistor T41 may be connected to the third transistor T3. A second electrode of the 4-1 transistor T41 may be connected to the first transistor T1 and the first light emitting element De1. A gate electrode of the 4-1 transistor T41 may be connected to the n-th second scan line L13. Thus, the 4-1 transistor T41 may receive the n-th second scan signal Scan2(n) and may be turned on or off by the n-th second scan signal Scan2(n).

[0106] In an embodiment, the 4-2nd transistor T42 may be connected to at least one of the second transistor T2, the third transistor T3, and the second light emitting element De2.

[0107] For example, a first electrode of the 4-2 transistor T42 may be connected to the third transistor T3. A second electrode of the 4-2 transistor T42 may be connected to the second transistor T2 and the second light emitting element De2. A gate electrode of the 4-2 transistor T42 may be connected to the n-th second scan line L13. Thus, the 4-2 transistor T42 may receive the n-th second scan signal Scan2(n) and may be turned on or off by the n-th second scan signal Scan2(n).

[0108] In an embodiment, the fifth transistor T5 may be connected to at least one of the driving transistor DT, the (4-1)th transistor T41, the (4-2)th transistor T42, the capacitor Cst, and the seventh transistor T7.

[0109] For example, a first electrode of the fifth transistor T5 may be connected to the driving transistor DT and the capacitor Cst. A second electrode of the fifth transistor T5 may be connected to the driving transistor DT and the seventh transistor T7. A gate electrode of the fifth transistor T5 may be connected to the nth second scan line L13 that supplies a second scan signal Scan2(n) in the nth row. The fifth transistor T5 may receive the nth second scan signal Scan2(n) and may be turned on or off by the nth second scan signal Scan2(n).

[0110] According to an embodiment, the nth first scan line L18 may provide the nth first scan signal. In this case, the nth first scan signal may be provided to the gate electrode of the sixth transistor T6. The nth second scan line L13 may provide the nth second scan signal. In this case, the nth second scan signal may be provided to the gate electrodes of the 4-1st transistor T41, the 4-2nd transistor T42, and the fifth transistor T5.

[0111] In an embodiment, the sixth transistor T6 may be connected to at least one of the third transistor T3 and the capacitor Cst.

[0112] For example, a first electrode of the sixth transistor T6 may be connected to the third transistor T3 and the capacitor Cst. A second electrode of the sixth transistor T6 may be connected to a data line L16 that supplies a data voltage Vdata. A gate electrode of the sixth transistor T6 may be connected to an nth first scan line L18 that supplies an nth first scan signal Scan1(n). The sixth transistor T6 may receive the nth first scan signal Scan1(n) and may be turned on or off by the nth first scan signal Scan1(n). When the sixth transistor T6 is turned on, the data voltage Vdata may be transferred from the second electrode to the first electrode.

[0113] In an embodiment, the seventh transistor T7 may be connected to at least one of the first transistor T1, the second transistor T2, the fifth transistor T5, and the driving transistor DT.

[0114] For example, a first electrode of the seventh transistor T7 may be connected to at least one of the fifth transistor T5 and the driving transistor DT. A second electrode of the seventh transistor T7 may be connected to at least one of the first transistor T1 and the second transistor T2. A gate electrode of the seventh transistor T7 may be connected to an emission signal line L30 that provides an emission signal EM(n). The seventh transistor T7 may be turned on or off based on the emission signal EM(n). When the seventh transistor T7 is turned on, a voltage (or current) may be provided from the first electrode to the second electrode of the seventh transistor T7.

[0115] In the embodiment, the first light emitting element De1 and / or the second light emitting element De2 may be connected to a third power wiring L19 that supplies a low potential power voltage ELVSS. For example, the cathode electrode of the first light emitting element De1 and the cathode electrode of the second light emitting element De2 may be connected to the third power wiring L19 to receive the low potential power voltage ELVSS.

[0116] According to an embodiment, the low potential power supply voltage may be a ground voltage (e.g., 0V (volt)). For example, the cathode electrode of the first light emitting element De1 and the cathode electrode of the second light emitting element De2 may receive a voltage corresponding to the ground, but is not limited thereto.

[0117] Hereinafter, a means for selectively configuring a first mode of a wide viewing angle mode and a second mode of a narrow viewing angle mode will be described with reference to FIGS.

[0118] First, Fig. 5 and Fig. 6 are perspective views of a lens according to an embodiment of the present disclosure. Fig. 5 shows a first lens 232 of a display device according to an embodiment of the present disclosure, and Fig. 6 shows a second lens 234 of a display device according to an embodiment of the present disclosure.

[0119] 5, the first lens 232 is a half-spherical lens and has a semicircular cross section in the X and Y directions. Therefore, the first lens 232 limits the viewing angles in the X and Y directions. For example, the first light-emitting unit EA1 equipped with the hemispherical first lens 232 may have a narrow viewing angle of 30 degrees or less in both the up-down and left-right directions.

[0120] 5, the second lens 234 is a half-cylindrical lens having a rectangular cross section in the X direction and a semicircular cross section in the Y direction. Therefore, the second lens 234 limits the viewing angle in the Y direction, but does not limit the viewing angle in the length direction of the second lens 234, i.e., in the X direction. For example, the second light-emitting unit EA2 having the semi-cylindrical second lens 234 may have a narrow viewing angle of 30 degrees or less in the vertical direction and a wide viewing angle of 60 degrees or more in the horizontal direction.

[0121] 5 and 6, the first lens 232 and the second lens 234 both limit the viewing angle in the Y direction (always in the vertical narrow viewing mode). This is because, in the case of the display device 100 applied to an automobile, it is necessary to limit the vertical viewing angle so that the image is not reflected by the windshield of the automobile and obstructs the forward view.

[0122] In this way, the vertical narrow viewing mode and the horizontal narrow viewing mode can be realized by driving the first light-emitting section EA1, and the vertical narrow viewing mode and the horizontal wide viewing mode can be realized by driving the second light-emitting section EA2.

[0123] In other words, the light emitting display device according to one embodiment of the present specification can always have a narrow viewing angle in the vertical direction by using the first lens 232 and the second lens 234, and can selectively configure a wide viewing mode and a narrow viewing mode in the horizontal direction.

[0124] Regarding the formation of such a wide viewing angle and a narrow viewing angle, the viewing angle characteristics of the first lens 232 and the second lens 234 will be described in detail with reference to FIGS.

[0125] FIG. 7 is a diagram showing an optical profile for the viewing angle of a first lens of a display device according to an embodiment of the present specification, and FIG. 8 is a diagram showing an optical profile for the viewing angle of a second lens of a display device according to an embodiment of the present specification.

[0126] As shown in Figures 7 and 8, the first light-emitting unit EA1 equipped with a hemispherical first lens 232 has a narrow viewing angle of less than 30 degrees in both the vertical and horizontal directions, while the second light-emitting unit EA2 equipped with a semi-cylindrical second lens 234 has a narrow viewing angle of less than 30 degrees in the vertical direction and a wide viewing angle of more than 60 degrees in the horizontal direction.

[0127] Therefore, the vertical narrow viewing mode and the horizontal narrow viewing mode can be realized by driving the first light-emitting section EA1, and the vertical narrow viewing mode and the horizontal wide viewing mode can be realized by driving the second light-emitting section EA2.

[0128] That is, the display device according to the embodiment of the present specification always has a narrow viewing angle in the vertical direction by the first and second lenses 232, 234, and can selectively realize a wide viewing mode or a narrow viewing mode in the horizontal direction.

[0129] FIG. 9 is an enlarged plan view of a display device according to one embodiment of the present specification, and FIGS. 10 to 12 are enlarged plan views of areas B and C of FIG.

[0130] With the above-mentioned configuration, the viewing angle of a part of the display device 100 can be adjusted so that an image displayed in the part of the display device 100 cannot be viewed from a specific direction. Here, a configuration for making the boundary between a region where the viewing angle control function is realized and a region where the viewing angle control function is not realized indiscernible will be described with reference to FIGS. 10 to 12 together with FIG. 9.

[0131] The display device 100 may include a first region S1 and a second region S2. As described below, the first region S1 and the second region S2 are adjacent regions, and based on a boundary BD, the first region S1 may be a CID region or a cluster region where a viewing angle adjustment function is not realized, and the second region S2 may be a CDD region where a viewing angle adjustment function is realized.

[0132] The first region S1 and the second region S2 may be classified according to whether or not they have a viewing angle adjustment function, and both regions may be included in the CDD region.

[0133] As described above, each of the first subpixel SP1, the second subpixel SP2 and the third subpixel SP3 may have at least one first light-emitting portion EA1 and at least one second light-emitting portion EA2, and a first lens 232 or a second lens 234 is disposed on each light-emitting portion so as to operate in a first mode or a second mode by individual light-emitting control of the light-emitting portions.

[0134] For this reason, each sub-pixel is divided into a plurality of light-emitting regions. Taking the first region S1, which does not need to control the viewing angle, as an example, when the above-mentioned configuration is applied, there may be a problem that the light-emitting area and brightness may be reduced compared to a pixel consisting of a single light-emitting region.

[0135] To solve this problem, referring to FIG. 9, the display device 100 is described as having a first region S1 that does not require viewing angle control and a second region S2 that requires viewing angle control as an example. The above-mentioned first region S1 and second region S2 may include sub-pixels having different configurations based on the boundary BD.

[0136] The sub-pixels in the first region S1 that do not require a viewing angle control function may be configured to include only the second lenses 234, which may be more advantageous in terms of viewing angle and brightness.

[0137] First, the pixel configuration of region B included in the second region S2 in which the viewing angle control function is realized will be described in more detail with reference to FIG.

[0138] As shown in FIG. 10, a pixel of the display device according to the embodiment includes first, second and third subpixels SP1, SP2 and SP3, which may be red, green and blue subpixels, respectively.

[0139] Each of the first, second and third sub-pixels SP1, SP2 and SP3 has at least a first light-emitting portion EA1 and a second light-emitting portion EA2. The first light-emitting portion EA1 of the first, second and third sub-pixels SP1, SP2 and SP3 may include at least one sub-light-emitting portion EA1a, where one sub-light-emitting portion EA1a corresponds to one first lens 232 and the second light-emitting portion EA2 corresponds to the second lens 234.

[0140] Here, the first and second subpixels SP1 and SP2 are arranged along the Y direction, and the third subpixel SP3 is arranged along the X direction relative to the first and second subpixels SP1 and SP2. Here, the first emission portion EA1 of the first and second subpixels SP1 and SP2 may be located between the second emission portion EA2 of the first subpixel SP1 and the second emission portion EA2 of the second subpixel SP2. This configuration may be reversed in the subpixels adjacent in the Y direction, or a structure in which the opposite configurations are repeated may be used.

[0141] In addition, the first light-emitting portion EA1 of the third subpixel SP3 may be arranged adjacent to the first light-emitting portion EA1 of the first subpixel SP1 and the first light-emitting portion EA1 of the second subpixel SP2 in the X-direction, and the second light-emitting portion EA2 of the third subpixel SP3 may be arranged adjacent to the second light-emitting portion EA2 of the first subpixel SP1 in the X-direction.

[0142] In this arrangement, the first light emitting unit EA1 or the second light emitting unit EA2 is disposed adjacent to each other in each sub-pixel, thereby making it possible to suppress problems such as distortion or moire in image display.

[0143] Each of the first, second and third subpixels SP1, SP2 and SP3 may have a polygonal shape. Here, the shapes of the first, second and third subpixels SP1, SP2 and SP3 may be different from each other. However, the present invention is not limited thereto, and the first, second and third subpixels SP1, SP2 and SP3 may have various shapes.

[0144] The first, second and third subpixels SP1, SP2 and SP3 have different areas. The areas of the first, second and third subpixels SP1, SP2 and SP3 can be determined in consideration of the lifetime and luminous efficiency of the light emitting element included in each subpixel. Here, since the shorter the wavelength of light is, the higher the energy is, the blue light emitting element has the shortest lifetime and the red light emitting element has the longest lifetime for the same area. Therefore, in order to make the lifetimes uniform, the area of ​​the second subpixel SP2 is larger than the area of ​​the first subpixel SP1 and smaller than the area of ​​the third subpixel SP3.

[0145] For example, the area ratio of the first, second and third subpixels SP1, SP2 and SP3 may be 1:2.5:3. In addition, the area ratio of the first light emitting units EA1 of the first, second and third subpixels SP1, SP2 and SP3 may also be 1:2.5:3, and the area ratio of the second light emitting units EA2 of the first, second and third subpixels SP1, SP2 and SP3 may also be 1:2.5:3. Therefore, the number of sub light emitting units EA1a of the first light emitting unit EA1 of the second subpixel SP2 may be greater than the number of sub light emitting units EA1a of the first light emitting unit EA1 of the first subpixel SP1 and less than the number of sub light emitting units EA1a of the first light emitting unit EA1 of the third subpixel SP3. Specifically, the first light-emitting portion EA1 of the first sub-pixel SP1 includes two sub-light-emitting portions EA1a, the first light-emitting portion EA1 of the second sub-pixel SP2 includes five sub-light-emitting portions EA1a, and the first light-emitting portion EA1 of the third sub-pixel SP3 includes six sub-light-emitting portions EA1a.

[0146] The sub-light emitting units EA1a may be a pixel group EG sharing one pixel electrode. Here, two sub-light emitting units EA1a of the first sub-pixel SP1 and three sub-light emitting units EA1a of the second sub-pixel SP2 may be substantially arranged in the X direction, four sub-light emitting units EA1a of the third sub-pixel SP3 and one sub-light emitting unit EA1a of the second sub-pixel SP2 may be substantially arranged in the X direction, and two sub-light emitting units EA1a of the third sub-pixel SP3 and one sub-light emitting unit EA1a of the second sub-pixel SP2 may be substantially arranged in the X direction.

[0147] However, the present invention is not limited thereto, and the area ratio of the first, second and third sub-pixels SP1, SP2 and SP3 and the number of the sub-light-emitting portions EA1a may be changed.

[0148] 11, the second lenses 234 may be disposed on the light-emitting portions of the subpixels corresponding to the first region S1 where the viewing angle control function is not required. Alternatively, a single second lens 234 may be disposed on at least one light-emitting portion. For example, the second lenses 234 may be disposed on the plurality of sub-light-emitting portions EA1a of the illustrated second subpixel SP2 and third subpixel SP3 so as to cover at least one sub-light-emitting portion EA1a.

[0149] Also, as shown in FIG. 12, in another embodiment of the present specification, the first light emitting portion EA1 and the second light emitting portion EA2 constituting the sub-pixel may be constituted by a single light emitting portion corresponding to a single second lens 234.

[0150] As an example, the first light-emitting portion EA1 of the third sub-pixel SP3 shown in FIG. 11 may include multiple sub-light-emitting portions EA1a, but as shown in FIG. 12, the first light-emitting portion EA1 of the third sub-pixel SP3 may be composed of a single light-emitting portion corresponding to one second lens 234.

[0151] Figures 13 and 14 are enlarged plan views of a display device according to an embodiment of the present specification. Figures 13 and 14 simply show the first light-emitting unit EA1 and the second light-emitting unit EA2, and do not show configurations such as lenses, but the first light-emitting unit EA1 and the second light-emitting unit EA2 can have the configurations shown in Figures 9 to 12.

[0152] A configuration for preventing the boundaries between the regions from being recognized will be described with reference to FIGS.

[0153] As described above, the pixels arranged in the first region S1 and the second region S2 may be configured to have different lenses or light-emitting regions to achieve the function of controlling the viewing angle.

[0154] In a display device having the above-described configuration, due to differences in the configuration of pixels or lenses arranged in each of the first region S1 and the second region S2, a problem may arise in which the driver or assistant driver perceives the boundary between the two regions of the display device, damaging the quality of the image.

[0155] A configuration capable of preventing the above-mentioned boundary from being recognized will be described below, and the viewing angle control mode and the shared mode will be described from the driver's viewpoint with reference to FIGS. 13 and 14, respectively.

[0156] 13 illustrates a display device for the driver's and assistant driver's viewpoints in a shared mode. Referring to FIG 13, the first region S1 may further include a third region S3 adjacent to the second region S2.

[0157] The first region S1 displays an image using both the first light-emitting unit EA1 and the second light-emitting unit EA2, and the second region S2 displays an image using only the second light-emitting unit EA2.

[0158] In the third region S3, the direction of the second region S2 is referred to as the first direction D1 and the opposite direction is referred to as the second direction D2, the first light-emitting unit of the third region S3 is driven to have a gradually increasing brightness in the second direction D2, and the second light-emitting unit of the third region S3 is driven to have a gradually increasing brightness in the first direction D1. Here, the first region S1 emits light from both the first light-emitting unit EA1 and the second light-emitting unit EA2, so that the first region S1 emits light at a lower brightness than the second light-emitting unit EA2 of the second region S2.

[0159] When the display device is configured in this manner, the average brightness of the first area L1 of the first area S1, the third area L3 of the second area S2, and the second area L2 of the third area S3 becomes uniform from the viewpoint of the driver and the assistant driver, thereby suppressing the phenomenon in which the boundary between the first area S1 and the second area S2 is perceived.

[0160] A configuration of a display device that suppresses the boundary between areas from being recognized from the viewpoint of an assistant driver in the viewing angle control mode will be described with reference to FIG.

[0161] Referring to FIG. 14, the first region S1 may further include a third region S3 adjacent to the second region S2.

[0162] The first region S1 displays an image using both the first light-emitting unit EA1 and the second light-emitting unit EA2, and the second region S2 displays an image using only the first light-emitting unit EA1.

[0163] In the first region S1, the direction of the second region S2 is referred to as the first direction D1, and the opposite direction is referred to as the second direction D2. The first light-emitting unit in the third region S3 is driven to have a gradually decreasing brightness in the second direction D2, and the second light-emitting unit in the third region S3 is driven to have a gradually decreasing brightness in the first direction D1. Here, since the first region S1 emits light from both the first light-emitting unit EA1 and the second light-emitting unit EA2, it emits light at a brightness lower than that of the first light-emitting unit EA1 in the second region S2.

[0164] When the display device is configured in this manner, the average brightness of the first area L1 of the first area S1, the third area L3 of the second area S2, and the second area L2 of the third area S3 becomes uniform from the viewpoint of the assistant driver, thereby suppressing the phenomenon in which the boundary between the first area S1 and the second area S2 is perceived.

[0165] Although the embodiments of the present invention have been described in detail above, the present invention is not necessarily limited to these embodiments, and can be modified in various ways without departing from the scope of the technical idea of ​​the present invention.
