[0038] When describing temporal relationships, discontinuous situations may be included when the temporal order is described as such as "after", "following", "next", and "before", unless more restrictive terms such as "only", "immediately", or "directly" are used.

[0039] Furthermore, when a component or layer is "connected," "joined," or "adhered" to another component or layer, this means that the component or layer can be directly connected or adhered to another component or layer, or indirectly connected or adhered to another component or layer, wherein one or more intermediate components or layers are "set" or "inserted" between the components or layers, unless otherwise specified.

It should also be understood that terms such as those defined in common dictionaries shall be interpreted as having a meaning consistent with, for example, their meaning in the context of the relevant field, and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0043] Instead, these embodiments may be provided so that this disclosure may be thorough and complete enough to help those skilled in the art to fully understand the scope of this disclosure.

[0044] The present disclosure will now be described in detail with reference to the accompanying drawings.

[0045] Figure 1 This is an example of a display device according to an exemplary embodiment of the present disclosure.

[0046] The display device 100 may be disposed in at least a portion of the vehicle instrument panel DB. The vehicle instrument panel DB includes configurations disposed on the front surface of the front seats of the vehicle. For example, input configurations for operating various functions in the vehicle (e.g., air conditioning, audio system, or navigation system) may be configured on the vehicle instrument panel DB.

[0047] The display device 100 can be disposed on the front surface of the passenger seat of the instrument panel DB. For example, the display device 100 can be a passenger-side display CDD. Therefore, the display device 100 according to an exemplary embodiment of the present disclosure is disposed on the instrument panel DB of a vehicle to provide convenience to the passenger in the passenger seat. For example, the display device 100 can provide information unrelated to vehicle operation, such as information about entertainment, such as TV series, movies, or music.

[0048] The display device 100 can be positioned along the side surface of the driver's seat. For example, at the center of the display device 100, the angle between the normal of the display device 100 and the driver's seat can be a first angle θ1. For example, when the vertical distance between the display device 100 and the driver is Y, and the horizontal distance between the driver and the center of the display device 100 is X, tanθ1 = X / Y. For example, when X is 100cm and Y is 80cm, the first angle θ1 can be approximately 52 degrees, but is not limited to this.

[0049] The display device 100 can selectively provide images to the driver according to a mode. For example, in a first mode where the vehicle is stationary, the display device 100 can emit light toward the driver's seat with a viewing angle greater than a first angle θ1. When the first angle θ1 is approximately 52 degrees, in the first mode, the display device 100 can emit light toward the driver's seat with a viewing angle of approximately 60 degrees. Therefore, in the first mode, the driver and the front passenger can view the images on the display device 100 together.

[0050] Furthermore, in the second mode where the vehicle is in motion, the display device 100 can emit light towards the driver's seat with an angle of view smaller than the first angle θ1. For example, when the first angle θ1 is approximately 52 degrees, in the second mode, the display device 100 can emit light towards the driver's seat with an angle of view of approximately 50 degrees. Therefore, in the second mode, the front passenger can view the image on the display device 100, but the driver may be restricted from viewing the image on the display device 100.

[0051] Therefore, when the display device 100 is operated in the first mode while the vehicle is stationary, the driver and the front passenger can view the images on the display device 100 together. Furthermore, when the display device 100 is operated in the second mode while the vehicle is in motion, only the front passenger views the images on the display device 100 to ensure vehicle operation safety.

[0052] Figure 2 This is a schematic diagram of a display device according to exemplary embodiments of the present disclosure. Figure 2 For ease of description, only the display panel PN, the gating driver GD, the data driver DD, and the timing controller TC are shown among the various components of the display device 100.

[0053] Reference Figure 2 The display device 100 includes: a display panel PN, which includes a plurality of sub-pixels SP; a gating driver GD and a data driver DD, which provide various signals to the display panel PN; and a timing controller TC, which controls the gating driver GD and the data driver DD.

[0054] The gating driver GD provides multiple scan signals to multiple scan lines SL based on multiple gating control signals provided by the timing controller TC. Although in Figure 2 The image shows a gate driver GD positioned spaced apart from one side of the display panel PN, but the number of gate drivers GDs and their placement are not limited to this.

[0055] The data driver DD supplies data voltage to multiple data lines DL based on multiple data control signals and image data provided by the timing controller TC. The data driver DD uses a reference gamma voltage to convert image data into data voltage, and can supply the converted data voltage to multiple data lines DL.

[0056] The timing controller TC aligns externally input image data to provide the image data to the data driver DD. The timing controller TC can use externally input synchronization signals (such as dot clock signals, data enable signals, and horizontal / vertical synchronization signals) to generate gating control signals and data control signals. Furthermore, the timing controller TC provides the generated gating control signals and data control signals to the gating driver GD and the data driver DD, respectively, to control the gating driver GD and the data driver DD.

[0057] The display panel PN is a configuration for displaying images to the user and includes multiple subpixels SP. In the display panel PN, multiple scan lines SL and multiple data lines DL intersect each other, and multiple subpixels SP can be formed at the intersections of scan lines SL and data lines DL.

[0058] In the display panel PN, the display area (or active area) AA and the non-display area (or non-active area) NA can be defined.

[0059] The display area AA is the area in the display device 100 where an image is displayed. Within the display area AA, multiple sub-pixels SP constituting multiple pixels PX and pixel circuitry for driving the multiple sub-pixels SP can be provided. The multiple sub-pixels SP are the smallest units constituting the display area AA, and n sub-pixels SP form one pixel PX. In each of the multiple sub-pixels SP, a thin-film transistor for driving multiple light-emitting diodes (LEDs) can be provided. Depending on the type of the display panel PN, the multiple LEDs can be defined in different ways. For example, when the display panel PN is an inorganic light-emitting display panel PN, the LEDs can be light-emitting diodes (LEDs) or miniature light-emitting diodes (LEDs).

[0060] In the display area AA, multiple signal lines are provided, transmitting various signals to multiple sub-pixels SP. For example, the multiple signal lines may include multiple data lines DL providing data voltage to each sub-pixel in the multiple sub-pixels SP, and multiple scan lines SL providing scan signals to each sub-pixel in the multiple sub-pixels SP. The multiple scan lines SL extend in one direction within the display area AA to connect to the multiple sub-pixels SP, and the multiple data lines DL extend in a direction different from the one provided to connect to the multiple sub-pixels SP. Furthermore, low-potential power lines and high-potential power lines may also be provided in the display area AA, but are not limited to these.

[0061] The non-display area NA is the area where no image is displayed; therefore, the non-display area NA can be defined as the area extending from the display area AA. Within the non-display area NA, link lines, pad electrodes, or driver ICs, such as strobe driver ICs or data driver ICs, can be configured to transmit signals to the sub-pixels SP of the display area AA.

[0062] Meanwhile, the non-display area NA can be located on the rear surface of the display panel PN, that is, on the surface where no sub-pixels SP are set, or it can be omitted, and is not limited to what is shown in the figure.

[0063] Meanwhile, drivers such as gating driver GD, data driver DD, and timing controller TC can be connected to the display panel PN in various ways. For example, gating driver GD can be installed in the non-display area NA as a gate in panel (GIP), or installed between multiple sub-pixels SP in the display area AA as a gate in active area (GIA).

[0064] For example, the data driver DD and the timing controller TC are formed in separate flexible films and printed circuit boards. The display panel PN can be electrically connected to the data driver DD and the timing controller TC by bonding the flexible film and the printed circuit board to pad electrodes formed in the non-display area NA of the display panel PN.

[0065] As another example, when the gate driver GD is mounted in the display area AA in a GIA configuration and forms a side line SRL connecting the signal lines on the front surface of the display panel PN to the pad electrodes on the rear surface of the display panel PN to bond the flexible film and printed circuit board to the rear surface of the display panel PN, the non-display area NA on the front surface of the display panel PN can be minimized or reduced. Therefore, when the gate driver GD, data driver DD, and timing controller TC are connected to the display panel PN as described above, a virtually bezel-less design can be achieved.

[0066] The display panel PN of the display device 100 according to an exemplary embodiment of the present disclosure will be described in more detail below.

[0067] Figure 3 This is an enlarged plan view of the display area of ​​a display device according to an exemplary embodiment of the present disclosure.

[0068] Reference Figure 3 The display device 100 according to an exemplary embodiment of the present disclosure may include a plurality of pixels PX, each pixel PX including a plurality of subpixels SP. Each subpixel of the plurality of subpixels SP includes a plurality of light-emitting diodes and a plurality of pixel circuits to emit light independently. A pixel PX may include one or more red subpixels SPR, one or more green subpixels SPG, and one or more blue subpixels SPB. The plurality of pixels PX may also include subpixels SP that emit light of other colors besides red subpixels SPR, green subpixels SPG, and blue subpixels SPB, but is not limited thereto.

[0069] Reference Figure 3 The red subpixel SPR, green subpixel SPG, and blue subpixel SPB can be set along one direction. For example, the red subpixel SPR, green subpixel SPG, and blue subpixel SPB can be set along the row direction.

[0070] Each of the multiple sub-pixels SP includes a first light-emitting diode 120 and a second light-emitting diode 130. For example, each of the red sub-pixel SPR, the green sub-pixel SPG, and the blue sub-pixel SPB may include a first light-emitting diode 120 and a second light-emitting diode 130.

[0071] The first LED 120 and the second LED 130 disposed in the same sub-pixel SP can be LEDs that emit light of the same color. That is, the first LED 120 and the second LED 130 disposed in the red sub-pixel SPR can be LEDs that emit the same red light. The first LED 120 and the second LED 130 disposed in the green sub-pixel SPG can be LEDs that emit the same green light, and the first LED 120 and the second LED 130 disposed in the blue sub-pixel SPB can be LEDs that emit the same blue light.

[0072] The first LED 120 and the second LED 130 can be arranged in the same row but different columns. In the column direction, the spacing between the first LED 120 and the black rim BB can be the same as the spacing between the second LED 130 and the black rim BB. Conversely, in the row direction, the spacing between the first LED 120 and the black rim BB is different from the spacing between the second LED 130 and the black rim BB.

[0073] The first light-emitting diode 120 can be disposed in the center portion of each sub-pixel SP. That is, in the row direction, the first light-emitting diode 120 can have the same spacing as the left black bezel and the right black bezel BB, but is not limited thereto. Furthermore, the spacing between the first light-emitting diode 120 and the left black bezel BB can be different from the spacing between the first light-emitting diode 120 and the right black bezel BB.

[0074] The second LED 130 can be configured to be biased to one side in each sub-pixel SP. For example, the second LED 130 can be located to the left of the first LED 120. Therefore, the second LED 130 can be located between the black rim BB and the first LED 120. Thus, in the row direction, the shortest distance between the first LED 120 and the black rim BB is greater than the shortest distance between the second LED 130 and the black rim BB.

[0075] In a sub-pixel SP, only one of the first LED 120 and the second LED 130 can be selectively driven. For example, the first LED 120 and the second LED 130 can be connected to different transistors. Therefore, by driving the transistors connected to the first LED 120 and the second LED 130 independently according to the mode, only one of the first LED 120 and the second LED 130 can be selectively driven.

[0076] At this time, 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 LED 120 can illuminate when a first mode signal is provided. When a predetermined second condition is met, the second LED 130 can illuminate when a second mode signal is provided. The first condition may include a condition pre-specified to drive in the first mode. The second condition may include a condition pre-specified to drive in the second mode. For example, the first condition may be a stopped vehicle state, and the second condition may be a moving vehicle state. Therefore, the first LED 120 can be driven when the vehicle is stopped, and the second LED 130 can be driven when the vehicle is moving.

[0077] The first light-emitting diode 120 can be configured to allow light emitted from the first light-emitting diode 120 to have a wide viewing angle in both the driver's seat direction and the passenger seat direction. Therefore, the light emitted from the first light-emitting diode 120 is visible to both the driver and the passenger.

[0078] The second light-emitting diode 130 can be configured to allow light emitted from the second light-emitting diode 130 to have a narrow viewing angle in the driver's seat direction and a wide viewing angle in the passenger's seat direction. Therefore, the light emitted from the second light-emitting diode 130 may be invisible to the driver but visible to the passenger.

[0079] The following will refer to Figure 5A and Figure 5B Describe in detail the viewing angles of the first light-emitting diode 120 and the second light-emitting diode 130.

[0080] A black dam (BB) is positioned between multiple sub-pixels (SP). The black dam is configured to surround each of the multiple sub-pixels to block light emitted from each sub-pixel (PX), thereby preventing the light from mixing or interfering and suppressing external light reflection. The black dam can limit the viewing angle of the first light-emitting diode (LED) 120 and the second light-emitting diode (LED) 130.

[0081] In the following text, reference will be made to Figure 4 A more detailed description of multiple sub-pixels SP.

[0082] Figure 4 This is a cross-sectional view of a sub-pixel of a display device according to an exemplary embodiment of the present disclosure.

[0083] refer to Figure 4 The first substrate 110 is a component for supporting various parts included in the display device 100 and may be formed of an insulating material. For example, the first substrate 110 may be formed of glass or resin. In addition, the first substrate 110 may be configured to include polymers or plastics, or may be formed of a flexible material.

[0084] A light-shielding layer LS is disposed on the first substrate 110 in each of the plurality of sub-pixels SP. The light-shielding layer LS blocks light incident from the bottom of the first substrate 110 onto the first active layer ACT1 of the first driving transistor DT1 and the second active layer ACT2 of the second driving transistor DT2. In the light-shielding layer LS, light incident onto the first active layer ACT1 of the first driving transistor DT1 and the second active layer ACT2 of the second driving transistor DT2 is blocked to minimize or reduce leakage current.

[0085] A buffer layer 111 is disposed on the first substrate 110 and the light-shielding layer LS. The buffer layer 111 can reduce the penetration of moisture or impurities through the first substrate 110. The buffer layer 111 may be composed of a single layer or a double layer of silicon oxide (SiOx) or silicon nitride (SiNx), but is not limited thereto. However, the buffer layer 111 may be omitted depending on the type of the first substrate 110 or the type of transistor, but is not limited thereto.

[0086] The first driving transistor DT1 and the second driving transistor DT2 are disposed on the buffer layer 111.

[0087] The first driving transistor DT1 includes a first active layer ACT1, a first gate electrode GE1, a first source electrode SE1, and a first drain electrode DE1.

[0088] The first active layer ACT1 is disposed on the buffer layer 111. The first active layer ACT1 may be formed of a semiconductor material such as oxide semiconductor, amorphous silicon or polycrystalline silicon, but is not limited thereto.

[0089] A gate insulating layer 112 is disposed on the first active layer ACT1. The gate insulating layer 112 is an insulating layer that insulates the first active layer ACT1 from the first gate electrode GE1, and may be composed of a single layer or a double layer of silicon oxide (SiOx) or silicon nitride (SiNx), but is not limited thereto.

[0090] The first gate electrode GE1 is disposed on the gate insulating layer 112. The first gate electrode GE1 may be made of a conductive material, such as copper (Cu), aluminum (Al), molybdenum (Mo), nickel (Ni), titanium (Ti), chromium (Cr) or alloys thereof, but is not limited thereto.

[0091] A first interlayer insulating layer 113 and a second interlayer insulating layer 114 are disposed on the first gate electrode GE1. Contact holes for connecting the first source electrode SE1 and the first drain electrode DE1 to the first active layer ACT1 can be formed in the first interlayer insulating layer 113 and the second interlayer insulating layer 114, respectively. The first interlayer insulating layer 113 and the second interlayer insulating layer 114 are insulating layers for protecting the components below the first interlayer insulating layer 113 and the second interlayer insulating layer 114, and can be composed of a single layer or a double layer of silicon oxide (SiOx) or silicon nitride (SiNx), but are not limited thereto.

[0092] A first source electrode SE1 and a first drain electrode DE1, electrically connected to the first active layer ACT1, are disposed on the second interlayer insulating layer 114. The first source electrode SE1 and the first drain electrode DE1 may be made of conductive materials, such as copper (Cu), aluminum (Al), molybdenum (Mo), nickel (Ni), titanium (Ti), chromium (Cr), or alloys thereof, but are not limited thereto.

[0093] This specification also describes a first interlayer insulating layer 113 and a second interlayer insulating layer 114, i.e., multiple insulating layers, disposed between the first gate electrode GE1 and the first source electrode SE1 and the first drain electrode DE1. However, only one insulating layer may be disposed between the first gate electrode GE1 and the first source electrode SE1 and the first drain electrode DE1, but it is not limited to this.

[0094] The second driving transistor DT2 includes a second active layer ACT2, a second gate electrode GE2, a second source electrode SE2, and a second drain electrode DE2.

[0095] The second active layer ACT2 is disposed on the buffer layer 111. The second active layer ACT2 can be made of the same material and formed on the same layer as the first active layer ACT1.

[0096] A gate insulating layer 112 is disposed on the second active layer ACT2, and a second gate electrode GE2 is disposed on the gate insulating layer 112. The second gate electrode GE2 can be formed on the same layer as the first gate electrode GE1 using the same material.

[0097] The first interlayer insulating layer 113 and the second interlayer insulating layer 114 are disposed on the second gate electrode GE2, and the second source electrode SE2 and the second drain electrode DE2, which are electrically connected to the second active layer ACT2, are disposed on the first interlayer insulating layer 113 and the second interlayer insulating layer 114. The second source electrode SE2 and the second drain electrode DE2 can be made of the same material and formed on the same layer as the first source electrode SE1 and the first drain electrode DE1.

[0098] Furthermore, as shown in the figure, when multiple insulating layers (such as a first interlayer insulating layer 113 and a second interlayer insulating layer 114) are provided between the first gate electrode GE1 and the first source electrode SE1 and the first drain electrode DE1, and between the second gate electrode GE2 and the second source electrode SE2 and the second drain electrode DE2, electrodes can also be formed between the first interlayer insulating layer 113 and the second interlayer insulating layer 114. The additionally formed electrodes can form a capacitor with other structures provided below the first interlayer insulating layer 113 or above the second interlayer insulating layer 114.

[0099] For example, a first conductive layer CL1 is disposed between a first interlayer insulating layer 113 and a second interlayer insulating layer 114, and a second conductive layer CL2 electrically connected to the first conductive layer CL1 can be disposed on the second interlayer insulating layer 114. The first conductive layer CL1 and the second conductive layer CL2 are configured to overlap with the first gate electrode GE1 of the first driving transistor DT1 to form a capacitor with the first gate electrode GE1 of the first driving transistor DT1. Furthermore, the first conductive layer CL1 and the second conductive layer CL2 are configured to overlap with the second gate electrode GE2 of the second driving transistor DT2 to form a capacitor with the second gate electrode GE2 of the second driving transistor DT2. Therefore, various conductive layers such as the first conductive layer CL1 and the second conductive layer CL2 are disposed on the first substrate 110 to form a capacitor.

[0100] Next, an auxiliary electrode BCNT is formed on the gate insulating layer 112. The auxiliary electrode BCNT is an electrode used to apply voltage to the light-shielding layer LS below the buffer layer 111. For example, the light-shielding layer LS is electrically connected to other structures formed on the first substrate 110 through the auxiliary electrode BCNT to apply voltage. The light-shielding layer LS, to which voltage is applied through the auxiliary electrode BCNT, does not operate as a floating gate, thus minimizing or reducing the threshold voltage fluctuation of the first driving transistor DT1 caused by the floating light-shielding layer LS, and also minimizing or reducing the threshold voltage fluctuation of the second driving transistor DT2.

[0101] A power line PL is disposed on the second interlayer insulating layer 114. The power line PL, together with the first driving transistor DT1, is electrically connected to the first light-emitting diode 120 to cause the first light-emitting diode 120 to emit light. Furthermore, the power line PL, together with the second driving transistor DT2, is electrically connected to the second light-emitting diode 130 to allow the second light-emitting diode 130 to emit light. The power line PL may be made of a conductive material such as copper (Cu), aluminum (Al), molybdenum (Mo), nickel (Ni), titanium (Ti), chromium (Cr), or alloys thereof, but is not limited thereto.

[0102] An organic insulating layer 115 is disposed on the first driving transistor DT1, the second driving transistor DT2, and the power line PL. The organic insulating layer 115 can planarize the upper part of the first substrate 110 on which the first driving transistor DT1 and the second driving transistor DT2 are disposed. The organic insulating layer 115 can be composed of a single layer or two layers, and can be formed, for example, by photoresist or acrylic organic materials, but is not limited thereto.

[0103] A plurality of first reflective electrodes RE1 and a plurality of second reflective electrodes RE2 spaced apart from each other can be disposed on the organic insulating layer 115. The plurality of first reflective electrodes RE1 and the plurality of second reflective electrodes RE2 electrically connect the first light-emitting diode 120 and the second light-emitting diode 130 to the power line PL, the first driving transistor DT1, and the second driving transistor DT2. Simultaneously, the plurality of first reflective electrodes RE1 and the plurality of second reflective electrodes RE2 serve as reflectors that reflect light emitted from the first light-emitting diode 120 and the second light-emitting diode 130 toward the top of the first substrate 110. The plurality of first reflective electrodes RE1 and the plurality of second reflective electrodes RE2 can be formed of a conductive material with excellent reflective properties. For example, the plurality of first reflective electrodes RE1 and the plurality of second reflective electrodes RE2 can be formed of a metallic material with excellent reflective properties, such as aluminum (Al), silver (Ag), copper (Cu), palladium (Pd), or alloys thereof, but are not limited thereto.

[0104] The plurality of first reflective electrodes RE1 includes a plurality of first-1 reflective electrodes RE1a and a plurality of first-2 reflective electrodes RE1b. The plurality of first-1 reflective electrodes RE1a may be disposed below the first light-emitting diodes 120 of the plurality of sub-pixels SP.

[0105] Multiple first-1 reflective electrodes RE1a can electrically connect the first light-emitting diode 120 to the first driving transistor DT1. The multiple first-1 reflective electrodes RE1a can be connected to the first source electrode SE1 or the first drain electrode DE1 of the first driving transistor DT1 through contact holes formed in the organic insulating layer 115. The multiple first-1 reflective electrodes RE1a can be electrically connected to the first p-type electrode 125 of the first light-emitting diode 120.

[0106] Multiple first- and second reflective electrodes RE1b can electrically connect the second light-emitting diode 130 to the second driving transistor DT2. The multiple first- and second reflective electrodes RE1b can be connected to the second source electrode SE2 or the second drain electrode DE2 of the second driving transistor DT2 through contact holes formed in the organic insulating layer 115. The multiple first- and second reflective electrodes RE1b can be electrically connected to the second p-type electrode 135 of the second light-emitting diode 130.

[0107] Multiple second reflective electrodes RE2 can electrically connect the power line PL to the first light-emitting diode 120 and the second light-emitting diode 130. The multiple second reflective electrodes RE2 can be electrically connected to the power line PL through contact holes formed in the organic insulating layer 115. Furthermore, the multiple second reflective electrodes RE2 can be electrically connected to the common electrode CE through contact holes in the first planarization layer 116. Therefore, the first n-type electrode 124 of the first light-emitting diode 120 and the second n-type electrode 134 of the second light-emitting diode 130 can be electrically connected to the power line PL through the multiple second reflective electrodes RE2 and the common electrode CE.

[0108] In each of the multiple sub-pixels SP, a first light-emitting diode 120 is disposed on the first-1 reflective electrode RE1a. The first light-emitting diode 120 is a light-emitting element that emits light through current, and may include light-emitting diodes that emit red, green, and blue light, and may achieve various colors of light, including white light, through combinations of red, green, and blue light. For example, the first light-emitting diode 120 may be a light-emitting diode (LED) or a micro LED, but is not limited thereto.

[0109] The first light-emitting diode 120 is a light-emitting diode that displays images to a user viewing the display panel N on the front and side surfaces of the first substrate 110. For example, when the display device 100 is installed in a vehicle, the first light-emitting diode 120 is a light-emitting diode that displays images to the driver and front passenger in the vehicle. Light emitted from the first light-emitting diode 120 can travel toward the front and side surfaces of the first substrate 110. At least some of the light emitted from the first light-emitting diode 120 is reflected by a plurality of first reflective electrodes RE1 and a plurality of second reflective electrodes RE2 to travel toward the front and side surfaces of the first substrate 110.

[0110] The first light-emitting diode 120 can be disposed at the same distance from the first black dam BB1 and the second black dam BB2. For example, the first light-emitting diode 120 can be disposed in the center portion between the first black dam BB1 and the second black dam BB2. Therefore, the spacing between the first light-emitting diode 120 and the first black dam BB1 can be the same as the distance between the first light-emitting diode 120 and the second black dam BB2.

[0111] Each first light-emitting diode 120 includes a first n-type semiconductor layer 121, a first light-emitting layer 122, a first p-type semiconductor layer 123, a first n-type electrode 124, a first p-type electrode 125, and a first encapsulation film 126.

[0112] A first p-type semiconductor layer 123 is disposed on the first-1 reflective electrode RE1a, and a first n-type semiconductor layer 121 is disposed on the first p-type semiconductor layer 123. The first p-type semiconductor layer 123 and the first n-type semiconductor layer 121 can be formed by doping p-type and n-type impurities into a specific material. For example, the first p-type semiconductor layer 123 and the first n-type semiconductor layer 121 can be layers in materials such as gallium nitride (GaN), indium aluminum phosphide (InAlP), or gallium arsenide (GaAs) doped with p-type and n-type impurities. The n-type impurity can be silicon (Si), germanium (Ge), and tin (Sn), and the p-type impurity can be magnesium (Mg), zinc (Zn), and beryllium (Be), but are not limited thereto.

[0113] The first light-emitting layer 122 is disposed between the first p-type semiconductor layer 123 and the first n-type semiconductor layer 121. Holes and electrons are supplied from the first p-type semiconductor layer 123 and the first n-type semiconductor layer 121 to the first light-emitting layer 122 to emit light. The first light-emitting layer 122 can be formed as a single-layer or multiple quantum well (MQW) structure, for example, it can be formed of indium gallium nitride (InGaN) or gallium nitride (GaN), but is not limited thereto.

[0114] A first p-type electrode 125 is disposed beneath the first p-type semiconductor layer 123. The first p-type electrode 125 may be disposed on the bottom surface of the first p-type semiconductor layer 123. The first p-type electrode 125 is an electrode for electrically connecting the first light-emitting diode 120, the first-1 reflective electrode RE1a, and the first driving transistor DT1. The first p-type electrode 125 contacts the first-1 reflective electrode RE1a to be electrically connected to it. The first p-type electrode 125 may be constructed of an opaque conductive material (e.g., titanium (Ti), gold (Au), silver (Ag), copper (Cu), or alloys thereof), a transparent conductive material (e.g., indium tin oxide (ITO) or indium zinc oxide (IZO)), or a combination of opaque and transparent conductive materials. However, this disclosure is not limited thereto.

[0115] A first n-type electrode 124 is disposed on the first n-type semiconductor layer 121. The first n-type electrode 124 is an electrode that electrically connects the common electrode CE and the first n-type semiconductor layer 121. The first n-type electrode 124 may be formed of a transparent conductive material to allow light emitted from the first light-emitting layer 122 to be guided to the top of the first substrate 110, i.e., the top of the first light-emitting diode 120. For example, the first n-type electrode 124 may be formed of a transparent conductive material, such as indium tin oxide (ITO) or indium zinc oxide (IZO), but is not limited thereto.

[0116] The first encapsulation film 126 is configured to surround at least a portion of the first p-type semiconductor layer 123, the first light-emitting layer 122, and the first n-type semiconductor layer 121. The first encapsulation film 126 is formed of an insulating material to protect the first p-type semiconductor layer 123, the first light-emitting layer 122, and the first n-type semiconductor layer 121. The first encapsulation film 126 may cover the side surfaces of the first p-type semiconductor layer 123, the first light-emitting layer 122, and the first n-type semiconductor layer 121. Furthermore, the first n-type electrode 124 and the first p-type electrode 125 are exposed from the first encapsulation film 126 to electrically connect the first n-type electrode 124 to the common electrode CE, and the first p-type electrode 125 may be electrically connected to the first-1 reflective electrode RE1a and the first driving transistor DT1. The first encapsulation film 126 is formed of any of the insulating materials, such as silicon oxide (SiOx) or silicon nitride (SiNx), but is not limited thereto.

[0117] In each of the multiple sub-pixels SP, a second light-emitting diode 130 is disposed on the first-second reflective electrode RE1b. The second light-emitting diode 130 is a light-emitting element that emits light through current, and may include light-emitting diodes that emit red, green, and blue light, and various colors of light, including white light, can be achieved by combinations of red, green, and blue light. For example, the second light-emitting diode 130 may be a light-emitting diode (LED) or a micro LED, but is not limited thereto.

[0118] The second light-emitting diode 130 is a light-emitting diode that displays an image to a user viewing the display panel PN on the front and side surfaces of the first substrate 110. Light emitted from the second light-emitting diode 130 can travel toward the front and side surfaces of the first substrate 110. At least some of the light emitted from the second light-emitting diode 130 is reflected by a plurality of first reflective electrodes RE1 and a plurality of second reflective electrodes RE2 so that it travels toward the front and side surfaces of the first substrate 110.

[0119] When the display device 100 is installed in a vehicle, the second light-emitting diode 130 is a light-emitting diode that displays an image to the passenger. For example, the light emitted from the second light-emitting diode 130 can be restricted to travel in a specific direction. For example, the travel of light emitted from the second light-emitting diode 130 towards the direction where the driver's seat is located can be restricted. Therefore, the light emitted from the second light-emitting diode 130 may not be visible to the driver. Conversely, the travel of light emitted from the second light-emitting diode 130 towards the direction where the passenger seat is located is unrestricted, and the light can be visible to the passenger.

[0120] The second LED 130 can be positioned closer to the first black dam BB1 than to the second black dam BB2. Therefore, the spacing between the second LED 130 and the first black dam BB1 can be smaller than the spacing between the second LED 130 and the second black dam BB2.

[0121] Furthermore, the second light-emitting diode 130 can be disposed between the first black dam BB1 and the first light-emitting diode 120. The second light-emitting diode 130 is configured to be closer to the first black dam BB1 than to the second black dam BB2, so that the second light-emitting diode 130 can be disposed between the first black dam BB1 and the first light-emitting diode 120.

[0122] Each second light-emitting diode 130 includes a second n-type semiconductor layer 131, a second light-emitting layer 132, a second p-type semiconductor layer 133, a second n-type electrode 134, a second p-type electrode 135, and a second encapsulation film 136.

[0123] A second p-type semiconductor layer 133 is disposed on the first-second reflective electrode RE1b, and a second n-type semiconductor layer 131 is disposed on the second p-type semiconductor layer 133. The second p-type semiconductor layer 133 and the second n-type semiconductor layer 131 can be formed by doping p-type and n-type impurities into a specific material. For example, the second n-type semiconductor layer 131 and the second p-type semiconductor layer 133 can be layers in materials such as gallium nitride (GaN), indium aluminum phosphide (InAlP), or gallium arsenide (GaAs) doped with p-type and n-type impurities. The n-type impurity can be silicon (Si), germanium (Ge), and tin (Sn), and the p-type impurity can be magnesium (Mg), zinc (Zn), and beryllium (Be), but are not limited thereto.

[0124] The second light-emitting layer 132 is disposed between the second n-type semiconductor layer 131 and the second p-type semiconductor layer 133. Holes and electrons are supplied from the second n-type semiconductor layer 131 and the second p-type semiconductor layer 133 to the second light-emitting layer 132 to emit light. The second light-emitting layer 132 may be formed of a single-layer or multiple quantum well (MQW) structure, for example, it may be formed of indium gallium nitride (InGaN) or gallium nitride (GaN), but is not limited thereto.

[0125] The second p-type electrode 135 is disposed below the second p-type semiconductor layer 133. The second p-type electrode 135 may be disposed on the bottom surface of the second p-type semiconductor layer 133. The second p-type electrode 135 is an electrode for electrically connecting the first-second reflective electrode RE1b and the second driving transistor DT2. The second p-type electrode 135 contacts the first-second reflective electrode RE1b to be electrically connected to it. The second p-type electrode 135 may be made of an opaque conductive material (e.g., titanium (Ti), gold (Au), silver (Ag), copper (Cu), or alloys thereof), a transparent conductive material (e.g., indium tin oxide (ITO) or indium zinc oxide (IZO)), or a combination of opaque and transparent conductive materials. However, this disclosure is not limited thereto.

[0126] The second n-type electrode 134 is disposed on the second n-type semiconductor layer 131. The second n-type electrode 134 is used to electrically connect the second light-emitting diode 130 to the power line PL together with the second reflective electrode RE2 and the common electrode CE. The second n-type electrode 134 is formed of a transparent conductive material, such as indium tin oxide (ITO) or indium zinc oxide (IZO), but is not limited thereto.

[0127] The second encapsulation film 136 is disposed around at least a portion of the second n-type semiconductor layer 131, the second light-emitting layer 132, and the second p-type semiconductor layer 133. The second encapsulation film 136 is formed of an insulating material to protect the second n-type semiconductor layer 131, the second light-emitting layer 132, and the second p-type semiconductor layer 133. The second encapsulation film 136 may cover the side surfaces of the second n-type semiconductor layer 131, the second light-emitting layer 132, and the second p-type semiconductor layer 133. Furthermore, the second n-type electrode 134 and the second p-type electrode 135 are exposed from the second encapsulation film 136 to electrically connect the second n-type electrode 134 and the common electrode CE, and the second p-type electrode 135 is electrically connected to the first-second reflective electrode RE1b and the second driving transistor DT2. The second encapsulation film 136 is formed of any of the insulating materials, such as silicon oxide (SiOx) or silicon nitride (SiNx), but is not limited thereto.

[0128] A first planarization layer 116 is disposed on a plurality of first reflective electrodes RE1 and a plurality of second reflective electrodes RE2. The first planarization layer 116 overlaps with a portion of the side of the first light-emitting diode 120 and a portion of the side of the second light-emitting diode 130 to fix and protect the first light-emitting diode 120 and the second light-emitting diode 130. The first planarization layer 116 may be composed of a single layer or two layers, and may be formed, for example, by photoresist or acrylic organic materials, but is not limited thereto.

[0129] A common electrode CE is disposed on the entire surface of the first substrate 110 on the first planarization layer 116. The common electrode CE is the electrode that electrically connects the power line PL to the first light-emitting diode 120 and the second light-emitting diode 130. The common electrode CE can be electrically connected to a plurality of second reflective electrodes RE2 through the contact holes of the first planarization layer 116. Therefore, the common electrode CE can be electrically connected to the power line PL through the plurality of second reflective electrodes RE2. Furthermore, the common electrode CE can be electrically connected to the first n-type electrode 124 and the second n-type electrode 315 of the first light-emitting diode 120 through the contact holes of the first planarization layer 116.

[0130] The common electrode CE is formed of a transparent conductive material to allow light emitted from the first light-emitting diode 120 and light emitted from the second light-emitting diode 130 to pass through. For example, the common electrode CE is formed of a transparent conductive material, such as indium tin oxide (ITO) or indium zinc oxide (IZO), but is not limited thereto.

[0131] A black dam BB surrounding multiple sub-pixels SP is disposed on a common electrode CE. The black dam BB can suppress the reflection of external light. The black dam BB can be formed of a material that absorbs or blocks light. For example, the black dam BB can be formed of an organic film containing a carbon-based black dye.

[0132] The black blister pack (BB) can block external light incident on the display device 100 from being reflected by the metal layer disposed on the first substrate 110 and traveling to the outside of the display device 100. For example, the black blister pack can block light reflected from the pixel circuit and reflective electrode RE disposed on the first substrate 110 from traveling to the outside of the display device 100.

[0133] Furthermore, black dams (BBs) can suppress color mixing that may occur between sub-pixels (SPs) that emit different colors of light. For example, black dams (BBs) are placed between adjacent sub-pixels (SPs) to absorb or block light traveling to the boundary of the sub-pixel (SP).

[0134] Meanwhile, the black dam BB can adjust the viewing angle of the first light-emitting diode 120 and the second light-emitting diode 130. For example, the black dam BB can block the light emitted from the first light-emitting diode 120 and the second light-emitting diode 130 and limit the viewing angle.

[0135] The following will refer to Figure 5A and Figure 5B The viewing angles of the black embankment BB, the first light-emitting diode 120, and the second light-emitting diode 130 are described in detail.

[0136] Black embankment BB can include first black embankment BB1 and second black embankment BB2.

[0137] The first black dam BB1 is disposed on one side of each sub-pixel in the plurality of sub-pixels SP, and the second black dam BB2 can be disposed on the other side of each sub-pixel in the plurality of sub-pixels SP. For example, one side may be the same direction as the direction in which the driver's seat is disposed, while the other side may be the same direction as the direction in which the passenger seat is disposed. For example, regarding Figure 3 and Figure 4 The first black dam BB1 is set to the left of each sub-pixel in the plurality of sub-pixels SP, and the second black dam BB2 can be set to the right of each sub-pixel in the plurality of sub-pixels SP.

[0138] The height of the first black dam BB1 and the height of the second black dam BB2 can be equal to each other. For example, the first black dam BB1 and the second black dam BB2 can be formed by the same process. Therefore, the first black dam BB1 and the second black dam BB2 can have the same height.

[0139] The first black dam BB1 can guide the light emitted from the first light-emitting diode 120 to be emitted to one side with a wide viewing angle. The first black dam BB1 can guide the light emitted from the second light-emitting diode 130 to be emitted to one side with a narrow viewing angle.

[0140] The second black dam BB2 can guide the light emitted from the first light-emitting diode 120 to emit it to the other side with a wide viewing angle. The second black dam BB2 can also emit the light emitted from the second light-emitting diode 130 to the other side with a wide viewing angle.

[0141] The following will refer to Figure 5A and Figure 5B The viewing angles of the black embankment BB, the first light-emitting diode 120, and the second light-emitting diode 130 are described in detail.

[0142] The second planarization layer 117 is disposed on the common electrode CE and the black dam BB. The second planarization layer 117 can be configured to fill the space between the first black dam BB1 and the second black dam BB2. For example, the top surface of the second planarization layer 117 can be disposed on the same plane as the top surfaces of the first black dam BB1 and the second black dam BB2. The second planarization layer 117 can be composed of a single layer or two layers, and can be formed, for example, by photoresist or acrylic organic materials, but is not limited thereto.

[0143] A protective layer 118 is disposed on the second planarization layer 117 and the black embankment BB. The protective layer 118 is a layer for protecting the components below it, and may be composed of a single or double layer of translucent epoxy resin, silicon oxide (SiOx) or silicon nitride (SiNx), but is not limited thereto.

[0144] The protective layer 118 may have a flat bottom surface and a flat top surface. For example, the bottom surface of the protective layer 118 may contact the top surface of the second planarization layer 117, the top surface of the first black dam BB1, and the top surface of the second black dam BB2 disposed on the same plane. The top surface of the protective layer 118 may contact the bottom surface of the second substrate 119.

[0145] The second substrate 119 is disposed on the protective layer 118. The second substrate 119 is a structure for protecting the display device 100 and can be formed of an insulating material. For example, the second substrate 119 can be formed of glass or resin.

[0146] At the same time, although Figure 4 The image is not shown, but an optical film may be disposed above or below the second substrate 119, such as an anti-scattering film, an anti-glare film, an anti-reflection film, a low-reflection film, an OLED transmittance controllable film, or a polarizer, but is not limited thereto.

[0147] In the following text, reference will be made to Figure 5A and Figure 5B Describe the viewing angles of the black embankment BB, the first light-emitting diode 120, and the second light-emitting diode 130.

[0148] Figure 5A This is a schematic diagram showing the view of a first light-emitting diode of a display device according to an exemplary embodiment of the present disclosure. Figure 5B This is a schematic diagram illustrating the viewing angle of the second light-emitting diode (LED) of a display device according to an exemplary embodiment of the present disclosure. The viewing angle of the first LED 120 and the second LED 130 refer to the maximum angle between the light emitted from the first LED 120 and the second LED 130 and the normal to the display device 100. Figure 5A and Figure 5B For ease of description, only the first light-emitting diode 120, the second light-emitting diode 130, the first black dam BB1, and the second black dam BB2 are shown.

[0149] The viewing angles of the first LED 120 and the second LED 130 can be determined by the spacing between the first LED 120 and the second LED 130 and the black dam BB1, as well as the height of the black dam BB1. For example, when the viewing angle of the first LED 120 on one side is θ2, the height of the first black dam BB1 is H, and the spacing between the first LED 120 and the first black dam BB1 is A, tan(θ2) = A / H. Similarly, when the viewing angle of the second LED 130 on one side is θ3, the height of the first black dam BB1 is H, and the spacing between the second LED 130 and the first black dam BB1 is B, tan(θ3) = B / H. Therefore, the smaller the spacing between the first LED 120 and the second LED 130 and the black dam BB1, the smaller the viewing angles of the first LED 120 and the second LED 130. Furthermore, the second LED 130 is positioned closer to the first black dam BB1 than the first LED 120, resulting in a viewing angle of the second LED 130 in the direction where the first black dam BB1 is located being smaller than the viewing angle of the first LED 120. Furthermore, the greater the height of the black embankment BB, the smaller the viewing angle of the first LED 120 and the second LED 130.

[0150] Reference Figure 5A The first light-emitting diode 120 is spaced apart from the first black dam BB1 and the second black dam BB2 at equal intervals, and the first black dam BB1 and the second black dam BB2 have the same height. Therefore, the viewing angle of the first light-emitting diode 120 on the other side can be equal to the viewing angle of the first light-emitting diode 120 on one side.

[0151] For example, suppose the width of a sub-pixel SP is approximately 42.6 μm. In this case, when the first light-emitting diode 120 is disposed in the center portion of each sub-pixel SP, the center of the first light-emitting diode 120 can be spaced approximately 21.3 μm from one end of the first black bead BB1 and approximately 21.3 μm from one end of the second black bead BB2.

[0152] At this time, when the height of the first black dam BB1 and the second black dam BB2 is about 12.3 μm or less, the viewing angle of the first light-emitting diode 120 toward the direction in which the first black dam BB1 is disposed and the direction in which the second black dam BB2 is disposed can be 60 degrees or greater.

[0153] Reference Figure 5B The second light-emitting diode 130 is spaced apart from the first black dam BB1 and the second black dam BB2 at different intervals. Therefore, the viewing angle of the second light-emitting diode 130 on the other side can be different from the viewing angle of the second light-emitting diode 130 on one side.

[0154] Specifically, when the direction in which the first black dam BB1 is disposed relative to the center of the second light-emitting diode 130 is one side, and the direction in which the second black dam BB2 is disposed relative to the center of the second light-emitting diode 130 is the other side, the viewing angle of the second light-emitting diode 130 on one side can be smaller than the viewing angle of the second light-emitting diode 130 on the other side.

[0155] Meanwhile, the second light-emitting diode 130 is positioned closer to the first black embankment BB1 than the first light-emitting diode 120. Therefore, the viewing angle of the second light-emitting diode 130 on one side can be smaller than the viewing angle of the first light-emitting diode 120 on one side.

[0156] For example, assuming that, considering process variations, the minimum spacing between the center of the second LED 130 and one end of the first black dam BB1 is 8 μm. Furthermore, the center of the first LED 120 is spaced approximately 21.3 μm from one end of the first black dam BB1 and one end of the second black dam BB2. Assuming that, considering process variations, the minimum spacing between the center of the first LED 120 and the center of the second LED 130 is approximately 8 μm. In this case, the spacing between that end of the first black dam BB1 and the center of the second LED 130 could be approximately 13 μm. Furthermore, correspondingly, the second LED 130 could be configured to be spaced approximately 8 μm to 13 μm from that end of the first black dam BB1.

[0157] At this time, when the height of the first black dam BB1 is approximately 10 μm, the viewing angle of the second LED 130 towards the direction in which the first black dam BB1 is located can be 50 degrees or less. Furthermore, when the height of the first black dam BB1 is approximately 7.5 μm, the viewing angle of the second LED 130 towards the direction in which the first black dam BB1 is located can be 50 degrees or less. However, when the height of the first black dam BB1 is approximately 5 μm, the viewing angle of the second LED 130 towards the direction in which the first black dam BB1 is located can exceed 55 degrees.

[0158] A passenger-side display can be positioned on the vehicle's dashboard in the direction of the front surface of the passenger seat to provide convenience for the passenger. For example, the passenger-side display can provide information unrelated to vehicle operation, such as entertainment information like TV shows, movies, or music. However, to ensure vehicle safety, the passenger-side display needs to selectively provide the image towards the direction of the driver's seat. For example, the passenger-side display controls the viewing angle to allow both the driver and passenger to view the image when the vehicle is stationary, and controls the viewing angle to allow only the passenger to view the image when the vehicle is moving. For example, the passenger-side display needs to control the viewing angle to provide various viewing angles when the vehicle is stationary and when the vehicle is moving.

[0159] In the display device 100 according to an exemplary embodiment of the present disclosure, the positions of the first light-emitting diode 120, the second light-emitting diode 130, and the black dam BB in a sub-pixel SP are adjusted to control the viewing angles of the first light-emitting diode 120 and the second light-emitting diode 130. For example, as the spacing between the black dam BB and the first light-emitting diode 120 and the second light-emitting diode 130 decreases and the height of the black dam BB increases, the viewing angles of the first light-emitting diode 120 and the second light-emitting diode 130 can be limited. At this time, when the first light-emitting diode 120 is disposed in the central portion of the sub-pixel SP, the first light-emitting diode 120 can have a wide viewing angle in all directions. Therefore, the light emitted from the first light-emitting diode 120 can be visible in all lateral directions. Conversely, when the second light-emitting diode 130 is disposed on the side of the sub-pixel SP, the second light-emitting diode 130 can have different viewing angles depending on the direction. Therefore, the light emitted from the second light-emitting diode 130 can be invisible in one direction but visible in another direction. Therefore, in the display device 100 according to an exemplary embodiment of the present disclosure, the spacing between the second light-emitting diode 130 and the black dam BB is adjusted to selectively have a narrow viewing angle in a specific area.

[0160] Furthermore, in the display device 100 according to an exemplary embodiment of the present disclosure, the viewing angles of the first light-emitting diode 120 and the second light-emitting diode 130 can be controlled using only the black diaphragm BB. Therefore, in the display device 100 according to an exemplary embodiment of the present disclosure, no separate component is required to control the viewing angle, thereby reducing the manufacturing process of the display device 100 and reducing manufacturing and product costs.

[0161] Figure 6 This is an enlarged plan view of the display area of ​​a display device according to another exemplary embodiment of the present disclosure. Figure 7This is a cross-sectional view of a sub-pixel of a display device according to another exemplary embodiment of the present disclosure. Except for the positions of the black diaphragm BB, the second planarization layer 617, and the first light-emitting diode 120 and the second light-emitting diode 130, Figure 6 and Figure 7 The display device 600 and Figures 1 to 4 The display device 100 is basically the same as the display device 100, so unnecessary descriptions are omitted.

[0162] Reference Figure 6 The first light-emitting diode 120 and the second light-emitting diode 130 are disposed in a plurality of sub-pixels SP. In each sub-pixel of the plurality of sub-pixels SP, the first light-emitting diode 120 and the second light-emitting diode 130 may be disposed in the same row but in different columns.

[0163] In addition to the position set in the sub-pixel SP Figure 6 and Figure 7 The configuration of the first light-emitting diode 120 and the second light-emitting diode 130 with Figures 1 to 5B The configurations of the first light-emitting diode 120 and the second light-emitting diode 130 are basically the same, so redundant descriptions will be omitted.

[0164] Refer to together Figure 7 The first light-emitting diode 120 and the second light-emitting diode 130 can be disposed on opposite sides of each sub-pixel SP. For example, the first light-emitting diode 120 can be disposed on the right side of the center portion of the sub-pixel SP, and the second light-emitting diode 130 can be disposed on the left side of the center portion of the sub-pixel SP. For example, in the row direction, the shortest distance between the first light-emitting diode 120 and the black dam BB can be the same as the shortest distance between the second light-emitting diode 130 and the black dam BB, but is not limited thereto.

[0165] In a sub-pixel SP, only one of the first light-emitting diode 120 and the second light-emitting diode 130 can be selectively driven. For example, the first light-emitting diode 120 can be driven when the vehicle is stationary, and the second light-emitting diode 130 can be driven when the vehicle is in motion.

[0166] The light emitted from the first LED 120 can be configured to have a wide viewing angle toward both the driver's seat and the front passenger seat. Therefore, the light emitted from the first LED 120 is visible to both the driver and the front passenger. Conversely, the light emitted from the second LED 130 can be configured to have a narrow viewing angle in the driver's seat direction and a wide viewing angle in the front passenger seat direction. Therefore, the light emitted from the second LED 130 may be invisible to the driver but visible to the front passenger.

[0167] The black dam BB is set between multiple sub-pixels SP. The black dam BB can include a first black dam BB1 and a second black dam BB2.

[0168] The first black dam BB1 is disposed on one side and the other side of each subpixel in the plurality of subpixels SP, and the second black dam BB2 can be disposed on the other side of each subpixel in the plurality of subpixels SP. For example, one side is the same direction as the direction in which the driver's seat is disposed, and the other side can be the same direction as the direction in which the passenger seat is disposed. For example, regarding Figure 6 and Figure 7 The first black dam BB1 is set to the left of each sub-pixel in the plurality of sub-pixels SP, and the second black dam BB2 can be set to the right of each sub-pixel in the plurality of sub-pixels SP.

[0169] The heights of the first black embankment BB1 and the second black embankment BB2 can be different from each other. For example, the height of the second black embankment BB2 is less than the height of the first black embankment BB1.

[0170] The first black dam BB1 and the second black dam BB2 can be formed using the same process. For example, the second black dam BB2 can be formed using a halftone mask to have a different height than the first black dam BB1, thus having a stepped shape. Alternatively, the first black dam BB1 and the second black dam BB2 can be formed separately using different processes.

[0171] The first black dam BB1 can guide the light emitted from the first light-emitting diode 120 to be emitted to one side with a wide viewing angle. The first black dam BB1 can guide the light emitted from the second light-emitting diode 130 to be emitted to one side with a narrow viewing angle.

[0172] The height of the second black dam BB2 is lower than that of the first black dam BB1, so that the light emitted from the first light-emitting diode 120 and the light emitted from the second light-emitting diode 130 are guided to be emitted to the other side with a wide viewing angle.

[0173] Simultaneously, light traveling from the first light-emitting diode 120 to the other side can also be guided by the first black dam BB1 of the adjacent sub-pixel SP. For example, in the light emitted from the first light-emitting diode 120, regarding... Figure 7 Light traveling to the right can be guided by the second black embankment BB2 and / or the first black embankment BB1 adjacent to the second black embankment BB2.

[0174] The following will refer to Figure 8 The viewing angles of the black embankment BB, the first light-emitting diode 120, and the second light-emitting diode 130 are described in detail.

[0175] A second planarization layer 617 is disposed on the black embankment BB. The second planarization layer 617 can be configured to fill the space between the first black embankment BB1 and the second black embankment BB2. Furthermore, the second planarization layer 617 can fill the step between the top surface of the first black embankment BB1 and the top surface of the second black embankment BB2. For example, the top surface of the second planarization layer 617 can be disposed on the same plane as the top surface of the second black embankment BB2. In this case, the second planarization layer 617 can cover the top surface of the second black embankment BB2 and the side surface of the first black embankment BB1 exposed by the second black embankment BB2.

[0176] In the following text, reference will be made to Figure 8 Describe the viewing angle of the black embankment BB, the first light-emitting diode 120, and the second light-emitting diode 130.

[0177] Figure 8 This is a schematic diagram of the viewing angle of a sub-pixel of a display device according to another exemplary embodiment of the present disclosure. The viewing angle of the first light-emitting diode 120 and the second light-emitting diode 130 refers to the maximum angle between the light emitted from the first light-emitting diode 120 and the second light-emitting diode 130 and the normal to the display device 100. Figure 8 For ease of description, only the first light-emitting diode 120, the second light-emitting diode 130, the first black dam BB1, and the second black dam BB2 are shown.

[0178] The viewing angles of the first LED 120 and the second LED 130 can be determined by the spacing between the first LED 120 and the second LED 130 and the black dam BB, as well as the height of the black dam BB. For example, the smaller the spacing between the first LED 120 and the second LED 130 and the black dam BB, the smaller the viewing angles of the first LED 120 and the second LED 130. Furthermore, the greater the height of the black dam BB, the smaller the viewing angles of the first LED 120 and the second LED 130.

[0179] In the following text, for ease of description, it is assumed that the direction in which the first black dam BB1 is set relative to the center of the first light-emitting diode 120 is one side, and the direction in which the second black dam BB2 is set is the other side.

[0180] Reference Figure 8 The first light-emitting diode 120 is spaced apart from the first black dam BB1 and the second black dam BB2 at different intervals. Therefore, the viewing angle of the first light-emitting diode 120 on the other side may be different from the viewing angle of the first light-emitting diode 120 on one side. Similarly, the second light-emitting diode 130 is spaced apart from the first black dam BB1 and the second black dam BB2 at different intervals. Therefore, the viewing angle of the second light-emitting diode 130 on the other side may be different from the viewing angle of the second light-emitting diode 130 on one side.

[0181] The second LED 130 is positioned closer to the first black dam BB1 than the first LED 120. Therefore, the viewing angle of the second LED 130 on one side is smaller than the viewing angle of the first LED 120 on the same side. Furthermore, the first LED 120 is positioned closer to the second black dam BB2 than the second LED 130. Therefore, the viewing angle of the first LED 120 on the other side can be smaller than the viewing angle of the second LED 130 on the other side.

[0182] Meanwhile, the height of the second black dam BB2 is less than the height of the first black dam BB1. Therefore, the viewing angle of the second LED 130 on one side is different from the viewing angle of the first LED 120 on the other side. For example, when the viewing angle of the second LED 130 on one side is θ4, the height of the first black dam BB1 is H1, and the distance between the second LED 130 and the first black dam BB1 is C, tan(θ4) = C / H1. When the viewing angle of the first LED 120 on the other side is θ5, the height of the second black dam BB2 is H2, and the distance between the first LED 120 and the second black dam BB2 is D, tan(θ5) = D / H2. Therefore, even if H1 equals H2, θ4 and θ5 can be different if C is different from D.

[0183] The following table 1 summarizes the position of the second light-emitting diode 130 and the height of the first black embankment BB1 used to form the second light-emitting diode 130 with a viewing angle of 50 degrees or less on one side.

[0184] [Table 1]

[0185]

[0186] Referring to Table 1, it can be confirmed that the greater the distance between the center of the second light-emitting diode 130 and one end of the first black dam BB1, the greater the minimum height of the second black dam used to make the second light-emitting diode 130 form an angle of 50 degrees or less on one side.

[0187] The following table 2 summarizes the positions of the first light-emitting diode 120 and the heights of the second black embankment BB2 used to enable the first light-emitting diode 120 to form a viewing angle of 60 degrees or greater on the other side.

[0188] [Table 2]

[0189]

[0190] Referring to Table 2, it can be confirmed that the greater the distance between the center of the first light-emitting diode 120 and one end of the second black dam BB2, the greater the minimum height of the second black dam BB2 used to enable the first light-emitting diode 120 to form an angle of 50 degrees or less on the other side.

[0191] Referring to Tables 1 and 2, even if the distance between the center of the first LED 120 and one end of the second black dam BB2, and the distance between the center of the second LED 130 and one end of the first black dam BB1, are equal, if the height of the first black dam BB1 is different from the height of the second black dam BB2, it can be confirmed that the viewing angle of the second LED 130 on one side is different from the viewing angle of the first LED 120 on the other side. For example, when the distance between the center of the first LED 120 and one end of the second black dam BB2, and the distance between the center of the second LED 130 and one end of the first black dam BB1, are approximately 8 μm, if the height of the first black dam BB1 is approximately 6.7 μm, it is confirmed that the viewing angle of the second LED 130 on one side is 50 degrees or less. Furthermore, it is further confirmed that if the height of the second black dam BB2 is approximately 4.6 μm, the viewing angle of the first LED 120 on the other side is 60 degrees or greater. Therefore, even if the shortest distance between the first LED 120 and the black embankment BB and the shortest distance between the second LED 130 and the black embankment BB are equal to each other, the viewing angle of the first LED 120 on one side and the viewing angle of the second LED 130 on the other side can be different from each other depending on the height of the first black embankment BB1 and the height of the second black embankment BB2.

[0192] Simultaneously, the viewing angle of the light from the first light-emitting diode 120 directed toward the direction where the second black dam BB2 is located is also guided by the first black dam BB1 located in another adjacent sub-pixel SP. For example, since the height difference between the second black dam BB2 and the first black dam BB1 is large or the width of the first black dam BB1 is small, the first black dam BB1 located in another adjacent sub-pixel SP reduces the viewing angle of the light from the first light-emitting diode 120 traveling toward the direction where the second black dam BB2 is located.

[0193] For example, refer to Figure 8 When the width of the second black dam BB2 is W, the height difference between the first black dam BB1 and the second black dam BB2 is H1-H2, and the viewing angle of the light from the first LED 120 traveling in the direction where the second black dam BB2 is located is θ5, tan(θ5) = W / (H1-H2). However, when the height difference between the second black dam BB2 and the first black dam BB1 is small, or the widths of the first black dam BB1 and the second black dam BB2 are large, the light from the first LED 120 whose viewing angle is limited by the second black dam BB2 can be visible to the driver and co-driver, without being limited by the first black dam BB1 located in another adjacent sub-pixel SP.

[0194] For example, assuming process variations are taken into account, the minimum spacing between the center of the second LED 130 and one end of the first black dam BB1 is approximately 9 μm, and the minimum spacing between the center of the first LED 120 and one end of the second black dam BB2 is approximately 9.5 μm. Furthermore, assuming the minimum spacing between the center of the first LED 120 and the center of the second LED 130 is approximately 8 μm.

[0195] At this point, when the height of the first black dam BB1 is approximately 7.5 μm, the viewing angle of the second LED 130 towards the direction where the first black dam BB1 is located can be 50 degrees or less. Further, when the height of the second black dam BB2 is approximately 5.6 μm, the viewing angle of the first LED 120 towards the direction where the second black dam BB2 is located can be 60 degrees or greater. At this point, when the width of each of the first black dam BB1 and the second black dam BB2 is approximately 5 μm, the height difference between the second black dam BB2 and the first black dam BB1 is approximately 1.9 μm. Therefore, light with a viewing angle limited to approximately 60 degrees by the second black dam BB2 is visible to the driver and co-driver, without being limited by the first black dam BB1 located in another adjacent sub-pixel SP.

[0196] In a display device 600 according to another exemplary embodiment of the present disclosure, the positions of a first light-emitting diode 120, a second light-emitting diode 130, and a black dam BB are adjusted within a sub-pixel SP to control the viewing angles of the first light-emitting diode 120 and the second light-emitting diode 130. For example, as the spacing between the black dam BB and the first light-emitting diode 120 and the second light-emitting diode 130 decreases and the height of the black dam BB increases, the viewing angles of the first light-emitting diode 120 and the second light-emitting diode 130 can be limited. Therefore, when the first black dam BB1 is disposed on one side of each sub-pixel in a plurality of sub-pixels SP and the second black dam BB2 is disposed on the other side, the second light-emitting diode 130 disposed adjacent to the first black dam BB1 can have a narrower viewing angle on one side than the first light-emitting diode 120 spaced apart from the first black dam BB1. Therefore, in the display device 600 according to another exemplary embodiment of the present disclosure, the spacing between the first light-emitting diode 120 and the second light-emitting diode 130 and the black dam BB is adjusted to selectively have a narrow viewing angle in a specific area.

[0197] Furthermore, in a display device 600 according to another exemplary embodiment of this disclosure, the viewing angles of the first light-emitting diode 120 and the second light-emitting diode 130 can be controlled using only a black diaphragm (BB). Therefore, the manufacturing process of the display device 600 is reduced, thereby lowering manufacturing and product costs.

[0198] Furthermore, in a display device 600 according to another exemplary embodiment of the present disclosure, in a sub-pixel SP, the height of the second black dam BB2 disposed on the other side of each of the plurality of sub-pixels SP is different. Therefore, the first light-emitting diode 120 disposed adjacent to the second black dam BB2 has a wide viewing angle on both one side and the other side. Thus, without increasing the spacing between the first light-emitting diode 120 and the second black dam BB2, the first light-emitting diode 120 can have a wide viewing angle in the direction in which the second black dam BB2 is disposed, thereby reducing the size of each of the plurality of sub-pixels SP to achieve a high-resolution display device 600.
