Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, specifically to a display panel. Background Technology
[0002] With the development of electrification, intelligence, connectivity, and sharing in the automotive industry, in-vehicle displays are also evolving towards environmental integration. To achieve wood grain or leather-like textured displays in in-vehicle displays, conventional solutions involve attaching a textured film to the light-emitting surface of the display panel. When not in use, this film reflects ambient light, creating a textured pattern consistent with the surrounding environment. When in use, light from the display passes through this textured pattern, resulting in information embedded within the texture. However, the textured film in conventional solutions blocks a significant amount of light from the display, reducing the transmittance of emitted light and consequently lowering the brightness of the displayed image. Summary of the Invention
[0003] Embodiments of this application provide a display panel that can improve the problem of reduced display brightness in conventional vehicle-mounted display devices.
[0004] In a first aspect, embodiments of this application provide a display panel, including: substrate; A light-emitting device layer is disposed on the surface of the substrate, and the light-emitting device layer includes a plurality of light-emitting devices spaced apart, with a first spacing region between two adjacent light-emitting devices; A texture layer, at least a portion of which is located within at least a portion of the first spacing region, the texture layer comprising a first texture sublayer and a second texture sublayer, the first texture sublayer being disposed on the surface of the substrate, the second texture sublayer being disposed on the side of the light-emitting device layer away from the substrate, and the surface of the first texture sublayer away from the substrate being lower than the surface of the light-emitting device layer away from the substrate.
[0005] Furthermore, the second textured sublayer is disposed on a surface of the first textured sublayer away from the substrate, and the surface of the second textured sublayer away from the substrate is not higher than the surface of the light-emitting device layer away from the substrate.
[0006] Furthermore, the display panel also includes a metal bonding layer, which includes a plurality of spaced pads disposed on the surface of the substrate. The light-emitting device is mounted on the surface of the substrate through the pads. The edge of the texture layer is spaced from the pads, and the space is 5µm to 10µm.
[0007] Furthermore, the display panel also includes a lens layer, which includes a plurality of spaced-apart lens portions, each of which encloses each of the light-emitting devices, and a second spacing region between two adjacent lens portions, wherein the texture layer is located within the second spacing region.
[0008] Furthermore, the edges of the texture layer do not extend beyond the edges of the first spacing region.
[0009] Furthermore, the textured layer further includes a first encapsulation sub-layer, the first encapsulation sub-layer being disposed on a surface of the first textured sub-layer away from the substrate, and a second textured sub-layer being disposed on a surface of the first encapsulation sub-layer away from the substrate. The surface of the first encapsulation sub-layer away from the substrate is higher than the surface of the light-emitting device layer away from the substrate, and the transmittance of the second textured sub-layer is not less than 60%. In the view of the display panel from above, the second texture sub-layer overlaps with the first texture sub-layer and the light-emitting device layer.
[0010] Furthermore, the first encapsulation sublayer covers the light-emitting surface of the light-emitting device and a portion of the sidewall of the light-emitting device, and the first texture sublayer covers another portion of the sidewall of the light-emitting device.
[0011] Furthermore, the first encapsulation sublayer includes a plurality of first encapsulation sub-parts; The texture layer further includes a second encapsulation sub-layer, which includes a plurality of second encapsulation sub-parts. The first encapsulation sub-parts and the second encapsulation sub-parts are alternately arranged, and each second encapsulation sub-part covers each of the light-emitting devices. The refractive index of the second encapsulation sublayer is greater than that of the first encapsulation sublayer.
[0012] Furthermore, the area of the side of the second package portion away from the substrate is larger than the area of the side of the second package portion closer to the substrate.
[0013] Furthermore, the first textured sublayer includes a first substrate and first textured particles, the first textured particles being doped into the first substrate; the second textured sublayer includes a second substrate and second textured particles, the second textured particles being doped into the second substrate; and the concentration of the first textured particles doped into the first textured sublayer is greater than the concentration of the second textured particles doped into the second textured sublayer.
[0014] The beneficial effects of this application are: This application provides a display panel by setting the light-emitting device layer to include a plurality of spaced-apart light-emitting devices, with a first gap between adjacent light-emitting devices. At least a portion of the texture layer is located within at least a portion of the first gap, and the texture layer includes a first texture sublayer and a second texture sublayer. The first texture sublayer is disposed on the surface of the substrate, and the second texture sublayer is disposed on the side of the light-emitting device layer away from the substrate. The surface of the first texture sublayer away from the substrate is lower than the surface of the light-emitting device layer away from the substrate. This allows at least a portion of the texture layer to be located on the surface of the substrate, rather than entirely on the light-emitting side of the light-emitting device. Compared to conventional display devices that place the texture layer on the light-emitting surface, this reduces the obstruction of light from the light-emitting side of the light-emitting device by the texture layer, improves the transmittance of the display panel, and thus enhances the brightness of the displayed image. Furthermore, since the texture layer includes the first texture sublayer and the second texture sublayer, the structure of the texture layer formed by the superposition of the two layers is beneficial to improving the display effect of the texture pattern of the texture layer of the display panel.

Detailed Implementation

[0018] Furthermore, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words indicate two or more unless otherwise expressly specified.
[0019] The first embodiment of this application provides a first display panel 10, see reference. Figure 2 , Figure 3 , Figure 5 and Figure 15The display panel 10 includes a substrate 100, a light-emitting device layer 200, and a texture layer 300. The light-emitting device layer 200 is disposed on the surface of the substrate 100 and includes a plurality of spaced-apart light-emitting devices 210, with a first spacing region 220 between adjacent light-emitting devices 210. The texture layer 300 is located within the first spacing region 220 and includes a first texture sub-layer 310 and a second texture sub-layer 320. The first texture sub-layer 310 is disposed on the surface of the substrate 100, and a surface of the first texture sub-layer 310 away from the substrate 100 is lower than a surface of the light-emitting device layer 200 away from the substrate 100. The second texture sub-layer 320 is disposed on a surface of the first texture sub-layer 310 away from the substrate 100, and a surface of the second texture sub-layer 320 away from the substrate 100 is not higher than a surface of the light-emitting device layer 200 away from the substrate 100.
[0020] refer to Figure 1 Conventional automotive display devices attach a texture film 102 to the light-emitting surface of the display panel 101. When the display is not in use, the texture film reflects ambient light and displays a texture pattern consistent with the surrounding environment. When in use, the light from the display passes through the texture pattern, creating an effect where display information is contained within the texture. However, the texture film 102 in conventional automotive display devices blocks a significant amount of light from the display, reducing the transmittance of the emitted light and thus lowering the brightness of the displayed image. Therefore, this application provides a display panel 10, which includes a plurality of spaced light-emitting devices 210 in the light-emitting device layer 200, with a first spacing region 220 between adjacent light-emitting devices 210. A texture layer 300 is located within the first spacing region 220, and the texture layer 300 includes a first texture sublayer 310 and a second texture sublayer 320. The first texture sublayer 310 is disposed on the surface of the substrate 100, and the surface of the first texture sublayer 310 away from the substrate 100 is lower than the surface of the light-emitting device layer 200 away from the substrate 100. The second texture sublayer 310... Layer 320 is disposed on a surface of the first textured sublayer 310 away from the substrate 100, and the surface of the second textured sublayer 320 away from the substrate 100 is not higher than the surface of the light-emitting device layer 200 away from the substrate 100; this allows the textured layer 300 to be entirely located on the surface of the substrate 100, rather than on the light-emitting side of the light-emitting device 210. Compared with conventional display devices that place the textured layer 300 on the light-emitting surface, this reduces the obstruction of light from the light-emitting side of the light-emitting device 210 by the textured layer 300, improves the transmittance of the display panel 10, and thus enhances the brightness of the display screen 10.
[0021] In this embodiment, the thickness ratio of the first texture sub-layer 310 to the thickness of the light-emitting device layer 200 is 1 / 2 to 2 / 3. By setting the thickness ratio of the first texture sub-layer 310 to the thickness of the light-emitting device layer 200 to 1 / 2 to 2 / 3, it is beneficial to ensure the texture effect of the first texture sub-layer on the one hand, and to reduce the shading of light from a portion of the side of the light-emitting device by the first texture layer on the other hand, thus ensuring the light efficiency of the display panel.
[0022] In this embodiment, the first texture sublayer 310 is black ink, and the second texture sublayer 320 includes a second substrate and second texture particles, wherein the second texture particles are doped into the second substrate.
[0023] It is understood that in other embodiments, the first texture sublayer 310 may also use materials of other colors to display texture patterns of different colors, such as brown materials, white materials or gray materials.
[0024] In this embodiment, the material of the second substrate includes a transparent solvent, wherein the transparent solvent can be acrylic adhesive-based water or silicone adhesive-based adhesive.
[0025] It is understood that in this embodiment, black ink serves as a base layer and works in conjunction with the second texture sub-layer 320 to form the final texture pattern on the texture layer 300, thereby improving the display effect of the texture pattern on the display panel 10. The texture pattern can be a wood texture pattern or a leather texture pattern.
[0026] In this embodiment, the light-emitting device 210 is a Mini LED or a Micro LED.
[0027] In this embodiment, the display panel 10 is a direct display panel 10.
[0028] It is understood that the direct-view display panel 10 includes a Mini LED display panel 10 or a Micro LED display panel 10.
[0029] In this embodiment, reference Figure 4 , Figure 6 The light-emitting device 210 includes a red light-emitting device 211, a green light-emitting device 212, and a blue light-emitting device 213, which are arranged periodically.
[0030] In this embodiment, three light-emitting devices 210 arranged at intervals along the same direction form a pixel unit 200a. The three light-emitting devices 210 in the pixel unit 200a are of different colors, and the spacing between two adjacent pixel units 200a in the same direction is greater than the spacing between two adjacent light-emitting devices 210 in a single pixel unit 200a. In this embodiment, reference Figure 3 , Figure 4 The first spacing region 220 includes a first spacing sub-region 221 and a second spacing sub-region 222. The first spacing sub-region 221 is the region between two adjacent light-emitting devices 210 in a pixel unit 200a, and the second spacing sub-region 222 is the region between two adjacent pixel units 200a.
[0031] In this embodiment, the texture layer 300 is located within the first spacer sub-region 221 and the second spacer sub-region 222.
[0032] In this embodiment, reference Figure 5 , Figure 6 The texture layer 300 is located in the second spacer sub-region 222 between two adjacent pixel units 200a.
[0033] It is understood that in this embodiment, the texture layer 300 is disposed in the second spacer sub-region 222 of two adjacent pixel units 200a, rather than in the first spacer sub-region 221 of two adjacent light-emitting devices 210 of pixel units 200a, which helps to reduce the manufacturing difficulty of the display panel 10.
[0034] In this embodiment, reference Figure 3 , Figure 5 , Figure 7 , Figure 9 The edge of the texture layer 300 does not extend beyond the edge of the first interval region 220. By setting the edge of the texture layer 300 not to extend beyond the edge of the first interval region 220, the texture layer 300 can be prevented from blocking the light-emitting surface of the light-emitting device 210, which is beneficial for light to be emitted from the light-emitting surface of the light-emitting device 210, thereby ensuring the light emission efficiency of the display panel 10.
[0035] In this embodiment, the first texture sublayer 310 includes a plurality of spaced-apart first texture sub-parts, and the second texture sublayer 320 includes a plurality of spaced-apart second texture sub-parts, wherein the edges of the first texture sub-parts overlap with the edges of the second texture sub-parts.
[0036] The second embodiment of this application provides a second type of display panel 10. The second embodiment differs from the first embodiment in that, as described in the reference... Figure 2 , Figure 7 , Figure 8The display panel 10 further includes a metal bonding layer 400, which includes a plurality of spaced-apart pads 410 disposed on the surface of the substrate 100. The light-emitting device 210 is mounted on the surface of the substrate 100 via the pads 410. A spacing 'a' is provided between the edge of the texture layer 300 and the pads 410, and the spacing 'a' is 5µm to 10µm. Preferably, the spacing 'a' is 5.0µm, 5.1µm, 5.2µm, 5.3µm, 5.4µm, 5.5µm, 5.6µm, 5.7µm, 5.8µm, 5.9µm, 6.0µm, 6.1µm, 6.2µm, 6.3µm, 6.4µm, 6.5µm, 6.6µm, 6.7µm, 6.8µm, 6.9µm, 7.0µm, 7.1µm, 7.2µm, 7.3µm, or 7.4µm. m, 7.5um, 7.6um, 7.7um, 7.8um, 7.9um, 8.0um, 8.1um, 8.2um, 8.3um, 8.4um, 8.5um, 8.6um, 8.7um , 8.8um, 8.9um, 9.0um, 9.1um, 9.2um, 9.3um, 9.4um, 9.5um, 9.6um, 9.7um, 9.8um, 9.9um or 10.0um.
[0037] In this embodiment, since the light-emitting device 210 is electrically connected to the circuit on the substrate 100 through the pad 410, when manufacturing the display panel 10, the pad 410 is manufactured first, then the texture layer 300 is manufactured, and finally the light-emitting device 210 is manufactured on the pad 410. The texture layer 300 is easy to cover the pad 410, which makes the light-emitting device 210 manufactured on the pad 410 prone to poor contact, resulting in abnormal display of the display panel 10. Therefore, this application further includes a metal connection layer 400 in the display panel 10. The metal connection layer 400 includes a plurality of spaced pads 410. The plurality of pads 410 are disposed on the surface of the substrate 100. The light-emitting device 210 is mounted on the surface of the substrate 100 through the pads 410. The edge of the texture layer 300 and the pads 410 have a spacing a, which is 5um to 10um. This reduces the risk of the pads 410 being obscured by the texture layer 300, making the connection between the light-emitting device 210 and the pads 410 more stable, thereby improving the stability of the display screen of the display panel 10.
[0038] In this embodiment, the first textured sublayer 310 includes black ink.
[0039] In this embodiment, the second texture sublayer 320 includes a second substrate and second texture particles, wherein the second texture particles are doped into the second substrate.
[0040] It is understood that in this embodiment, black ink serves as a base layer and works in conjunction with the second texture sublayer 320 to form the final texture pattern on the texture layer 300. The texture pattern can be a wood texture pattern or a leather texture pattern.
[0041] In this embodiment, the first texture sublayer 310 includes a plurality of spaced-apart first texture sub-parts, and the second texture sublayer 320 includes a plurality of spaced-apart second texture sub-parts, wherein the edges of the first texture sub-parts overlap with the edges of the second texture sub-parts.
[0042] The third embodiment of this application provides a third type of display panel 10, see reference. Figure 2 , Figure 9 , Figure 10 as well as Figure 15 The display panel 10 includes a substrate 100, a light-emitting device layer 200, and a texture layer 300. The light-emitting device layer 200 is disposed on the surface of the substrate 100 and includes a plurality of spaced-apart light-emitting devices 210. A first spacing region 220 is formed between two adjacent light-emitting devices 210, and a portion of the texture layer 300 is located within the first spacing region 220. The texture layer 300 includes a first texture sublayer 310 and a second texture sublayer 320. The first texture sublayer 310 is disposed on the surface of the substrate 100, and the second texture sublayer 320 is disposed on the surface of the substrate 100. The sublayer 320 is disposed on the side of the light-emitting device layer 200 away from the substrate 100. The surface of the first texture sublayer 310 away from the substrate 100 is lower than the surface of the light-emitting device layer 200 away from the substrate 100. The display panel 10 also includes a lens layer 500. The lens layer 500 includes a plurality of spaced lens portions 510. Each lens portion 510 encloses each light-emitting device 210. There is a second spacing region 520 between two adjacent lens portions 510. The texture layer 300 is located within the second spacing region 520.
[0043] refer to Figure 1Conventional automotive display devices attach a texture film 102 to the light-emitting surface of the display panel 101. When the display is not in use, the texture film reflects ambient light and displays a texture pattern consistent with the surrounding environment. When in use, the light from the display passes through the texture pattern, creating an effect where display information is contained within the texture. However, the texture film 102 in conventional automotive display devices blocks a significant amount of light from the display, reducing the transmittance of the emitted light and thus lowering the brightness of the displayed image. Therefore, this application provides a display panel 10, which includes a plurality of spaced-apart light-emitting devices 210 in the light-emitting device layer 200, with a first spacing region 220 between adjacent light-emitting devices 210, and a portion of the texture layer 300 located within the first spacing region 220; the texture layer 300 includes a first texture sublayer 310 and a second texture sublayer 320, the first texture sublayer 310 being disposed on the surface of the substrate 100, and the second texture sublayer 320 being disposed on the side of the light-emitting device layer 200 away from the substrate 100, the surface of the first texture sublayer 310 away from the substrate 100 being lower than the surface of the light-emitting device layer 200 away from the substrate 100; the display panel 10 also includes a lens layer 500, which includes a plurality of spaced-apart lens portions. 510, each of the lens portions 510 encloses each of the light-emitting devices 210, and a second spacing region 520 is provided between two adjacent lens portions 510, wherein the texture layer 300 is located within the second spacing region 520; this allows the texture layer 300 to be entirely located on the surface of the substrate 100, rather than on the light-emitting side of the light-emitting device 210. Compared with conventional display devices where the texture layer 300 is placed on the light-emitting surface, this reduces the obstruction of light from the light-emitting side of the light-emitting device 210 by the texture layer 300, improves the transmittance of the display panel 10, and thus enhances the brightness of the display image on the display panel 10; furthermore, since the lens can act as a light-focusing element, it is more conducive to the light from the front of the light-emitting device 210 being emitted, thereby more effectively improving the brightness of the display image on the display panel 10.
[0044] In this embodiment, reference Figure 10 The second interval region 520 is connected to the first interval region 220.
[0045] Understandably, reference Figure 10 A portion of the second interval region 520 overlaps with a portion of the first interval region 220.
[0046] In this embodiment, reference Figure 9The thickness of the texture layer 300 is greater than the thickness of the light-emitting device layer 200, and the thickness of the texture layer 300 is less than the thickness of the lens layer 500. By setting the thickness of the texture layer 300 to be greater than the thickness of the light-emitting device layer 200 and less than the thickness of the lens layer 500, i.e., the texture layer 300 in this embodiment is thicker, it is beneficial to improve the touch feel of the display panel 10 on the one hand, and on the other hand, it can prevent the thickness of the texture layer 300 from exceeding the thickness of the lens layer 500 and blocking the light of the light-emitting device 210, thereby reducing the impact of the texture layer 300 on the light effect of the display panel 10.
[0047] In this embodiment, the first textured sublayer 310 includes black ink.
[0048] In this embodiment, the second texture sublayer 320 includes a second substrate and second texture particles, wherein the second texture particles are doped into the second substrate.
[0049] It is understood that in this embodiment, black ink serves as a base layer and works in conjunction with the second texture sub-layer 320 to form the final texture pattern on the texture layer 300, thereby enhancing the texture pattern effect of the display panel 10. The texture pattern can be a wood texture pattern or a leather texture pattern.
[0050] In this embodiment, the material of the second substrate includes a transparent solvent, wherein the transparent solvent can be acrylic adhesive-based water or silicone adhesive-based adhesive.
[0051] In this embodiment, the first texture sublayer 310 includes a plurality of spaced-apart first texture sub-parts, and the second texture sublayer 320 includes a plurality of spaced-apart second texture sub-parts, a portion of which extends beyond the edge of the first texture sub-parts.
[0052] The fourth embodiment of this application provides a fourth type of display panel 10, see reference. Figure 2 , Figure 11 , Figure 15The system includes a substrate 100, a light-emitting device layer 200, and a texture layer 300. The light-emitting device layer 200 is disposed on the surface of the substrate 100 and includes a plurality of spaced-apart light-emitting devices 210. A first spacing region 220 is formed between two adjacent light-emitting devices 210. A portion of the texture layer 300 is located within the first spacing region 220. The texture layer 300 includes a first texture sublayer 310 and a second texture sublayer 320. The first texture sublayer 310 is disposed on the surface of the substrate 100, and the second texture sublayer 320 is disposed on the side of the light-emitting device layer 200 away from the substrate 100. The surface of the first texture sublayer 310 away from the substrate 100 is lower than the surface of the substrate 100. The light-emitting device layer 200 has a surface away from the substrate 100. The texture layer 300 further includes a first encapsulation sub-layer 330. The first encapsulation sub-layer 330 is disposed on the surface of the first texture sub-layer 310 away from the substrate 100. The second texture sub-layer 320 is disposed on the surface of the first encapsulation sub-layer 330 away from the substrate 100. The surface of the first encapsulation sub-layer 330 away from the substrate 100 is higher than the surface of the light-emitting device layer 200 away from the substrate 100. The transmittance of the second texture sub-layer 320 is not less than 60%. In a top-view perspective of the display panel 10, the second texture sub-layer 320 overlaps with the first texture sub-layer 310 and the light-emitting device layer 200.
[0053] refer to Figure 1Conventional automotive display devices attach a texture film 102 to the light-emitting surface of the display panel 101. When the display is not in use, the texture film reflects ambient light and displays a texture pattern consistent with the surrounding environment. When in use, the light from the display passes through the texture pattern, creating an effect where display information is contained within the texture. However, the texture film 102 in conventional automotive display devices blocks a significant amount of light from the display, reducing the transmittance of the emitted light and thus lowering the brightness of the displayed image. Therefore, this application provides a display panel 10, which includes a plurality of spaced-apart light-emitting devices 210 in the light-emitting device layer 200, with a first spacing region 220 between adjacent light-emitting devices 210, and a portion of the texture layer 300 located within the first spacing region 220; the texture layer 300 includes a first texture sublayer 310, a first encapsulation sublayer 330, and a second texture sublayer 320, wherein the first texture sublayer 310 is disposed on the surface of the substrate 100, the first encapsulation sublayer 330 is disposed on the surface of the first texture sublayer 310 away from the substrate 100, and the second texture sublayer 320 is disposed on the surface of the first encapsulation sublayer 330 away from the substrate 100, the surface of the first texture sublayer 310 away from the substrate 100 is lower than the surface of the light-emitting device layer 200 away from the substrate 100, and the surface of the first encapsulation sublayer 330 away from the substrate 100 is higher than the surface of the light-emitting device layer 200 away from the substrate 100, and the second texture sublayer 310 is disposed on the surface of the first encapsulation sublayer 330 away from the substrate 100. The transmittance of the second texture layer 320 is not less than 60%. Specifically, from a top-view perspective of the display panel 10, the second texture layer 320 overlaps with the first texture layer 310 and the light-emitting device layer 200. This results in a portion of the texture layer 300 being located on the surface of the substrate 100, rather than entirely on the light-emitting side of the light-emitting device 210. Compared to conventional display devices where the texture layer 300 is placed on the light-emitting surface, this reduces the obstruction of light from the light-emitting side of the light-emitting device 210 by the texture layer 300, improving the transmittance of the display panel 10 and thus enhancing the brightness of the displayed image. Furthermore, since the second texture layer 320 covers the first texture layer 310 and the light-emitting device layer 200, and the transmittance of the second texture layer 320 is not less than 60%, on the one hand, the second texture layer 320 can block the surface color of the light-emitting device 210, improving the hiding effect of the display panel 10; on the other hand, it reduces the obstruction of light from the light-emitting device 210 by the second texture layer 320, ensuring the brightness of the displayed image of the display panel 10.
[0054] In this embodiment, the transmittance of the second textured sublayer 320 is 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, or 95%.
[0055] It is understood that in this embodiment, the second textured sublayer 320 forms the entire surface of the first encapsulation sublayer away from the substrate 100.
[0056] In this embodiment, reference Figure 11 The first encapsulation sublayer 330 covers the light-emitting surface of the light-emitting device 210 and a portion of the sidewall of the light-emitting device 210, while the first texture sublayer 310 covers the other portion of the sidewall of the light-emitting device 210. By setting the first encapsulation sublayer 330 to cover the light-emitting surface of the light-emitting device 210 and a portion of the sidewall of the light-emitting device 210, and the first texture sublayer 310 to cover the other portion of the sidewall of the light-emitting device 210, the first encapsulation sublayer 330 can protect the light-emitting device 210, preventing damage to the light-emitting surface of the light-emitting device 210 during the subsequent fabrication of the second texture sublayer 320, thereby ensuring the display effect of the display screen 10.
[0057] It is understood that, in this embodiment, the surface of the first encapsulation sublayer 330 that is away from the substrate 100 is higher than the surface of the light-emitting device layer 200 that is away from the substrate 100.
[0058] In this embodiment, the material of the first encapsulation sublayer 330 includes transparent acrylic or silicone.
[0059] In this embodiment, the first texture sublayer 310 includes a first substrate and first texture particles, the first texture particles being doped into the first substrate; the second texture sublayer 320 includes a second substrate and second texture particles, the second texture particles being doped into the second substrate.
[0060] In this embodiment, the material of the first substrate includes black ink.
[0061] In this embodiment, the first texture particle and the second texture particle are the same particle.
[0062] In this embodiment, the thickness of the second texture sublayer 320 is 1µm to 3µm. By setting the thickness of the second texture sublayer 320 to 1µm to 3µm, the excessive thickness of the second texture sublayer 320 can be avoided from affecting the light transmittance, thereby ensuring the display brightness of the image displayed on the display panel 10. Preferably, the thickness of the second texture sublayer 320 is 1µm, 1.1µm, 1.2µm, 1.3µm, 1.4µm, 1.5µm, 1.6µm, 1.7µm, 1.8µm, 1.9µm, 2.0µm, 2.1µm, 2.2µm, 2.3µm, 2.4µm, 2.5µm, 2.6µm, 2.7µm, 2.8µm, 2.9µm, or 3.0µm.
[0063] It is understood that in this embodiment, the first texture sublayer 310 and the second texture sublayer 320 can cooperate to form the final texture pattern of the texture layer 300, wherein the texture pattern can be a wood texture pattern or a leather texture pattern.
[0064] In this embodiment, the concentration of texture particles doped in the first texture sublayer 310 is greater than the concentration of texture particles doped in the second texture sublayer 320.
[0065] It is understood that in this embodiment, since the second texture sub-layer 320 covers the light-emitting device 210, the higher the concentration of texture particles in the second texture sub-layer 320, the stronger the light-blocking effect of the second texture sub-layer 320, resulting in a decrease in the light transmittance of the display panel 10 through the second texture sub-layer 320. Therefore, the concentration of texture particles doped in the first texture sub-layer 310 is set to be greater than the concentration of texture particles doped in the second texture sub-layer 320. On the one hand, this allows the first texture sub-layer 310 to serve as the main texture film layer for displaying texture patterns, ensuring the texture display effect. On the other hand, it reduces the light blocking effect of the second texture sub-layer 320, thereby ensuring the brightness of the display screen 10.
[0066] The fifth embodiment of this application provides a fifth type of display panel 10. The fifth embodiment is similar to the fourth embodiment, but differs from the fourth embodiment in that, in reference to... Figure 2 , Figure 12 , Figure 15The texture layer 300 further includes a second encapsulation sublayer 340, which includes a plurality of second encapsulation sub-parts 341, each of which covers each of the light-emitting devices 210; the first encapsulation sublayer 330 includes a plurality of first encapsulation sub-parts 331, which are alternately arranged with the second encapsulation sub-parts 341; wherein the refractive index of the second encapsulation sublayer 340 is greater than the refractive index of the first encapsulation sublayer 330. The texture layer 300 also includes a second encapsulation sublayer 340, which includes a plurality of second encapsulation sub-parts 341, each of which covers each of the light-emitting devices 210. The first encapsulation sublayer 330 includes a plurality of first encapsulation sub-parts 331, which are alternately arranged with the second encapsulation sub-parts 341. The refractive index of the second encapsulation sublayer 340 is greater than that of the first encapsulation sublayer 330, so that a portion of the light from the light-emitting device 210 undergoes total internal reflection when passing through the interface between the second encapsulation sub-parts 341 and the first encapsulation sub-parts 331, thereby increasing the amount of light emitted from the light-emitting surface of the light-emitting device 210 and improving the light emission efficiency of the display panel 10.
[0067] It is understood that in this embodiment, the second textured sublayer 320 forms the entire surface of the encapsulation sublayer away from the substrate 100.
[0068] In this embodiment, reference Figure 12 The area S1 of the second encapsulation sub-part 341 on the side away from the substrate 100 is larger than the area S2 of the side of the second encapsulation sub-part 341 close to the substrate 100. By setting the area S1 of the second encapsulation sub-part 341 on the side away from the substrate 100 to be larger than the area S2 of the side of the second encapsulation sub-part 341 close to the substrate 100, the interface between the second encapsulation sub-part 341 and the first encapsulation sub-part 331 can reflect light towards the light-emitting side of the display panel 10, thereby effectively improving the light emission efficiency of the display panel 10.
[0069] It is understood that in this embodiment, the interface between the second encapsulation sub-part 341 and the first encapsulation sub-part 331 is a slope.
[0070] The sixth embodiment of this application provides a sixth type of display panel 10. The sixth embodiment is similar to the fourth embodiment, but differs from the fourth embodiment in that, in reference to... Figure 2 , Figure 13 , Figure 14 From a top-down view of the display panel 10, the second texture sub-layer 320 overlaps with at least a portion of the first texture sub-layer 310.
[0071] In this embodiment, referenceFigure 13 From a top-down view of the display panel 10, the edge of the second texture sub-layer 320 is located within the first interval region 220. By setting the edge of the second texture sub-layer 320 to be located within the first interval region 220, the obstruction of light from the light-emitting device 210 by the second texture sub-layer 320 can be reduced, thereby ensuring the light emission effect of the display panel 10.
[0072] In this embodiment, the first texture sublayer 310 includes a plurality of spaced first texture sub-parts 311, and the second texture sublayer 320 includes a plurality of spaced second texture sub-parts 321.
[0073] It is understood that in this embodiment, each of the second texture sub-parts 321 is located above each of the first texture sub-parts 311.
[0074] In this embodiment, reference Figure 3 , Figure 4 The first spacing region 220 includes a first spacing sub-region 221 and a second spacing sub-region 222. The first spacing sub-region 221 is the region between two adjacent light-emitting devices 210 in a pixel unit 200a, and the second spacing sub-region 222 is the region between two adjacent pixel units 200a.
[0075] In this embodiment, reference Figure 14 The edge of the second texture sublayer 320 is located within the second spacer sub-region 222.
[0076] Understandably, reference Figure 14 In this embodiment, by setting the edge of the second texture sub-layer 320 to be located within the second interval sub-region 222, that is, by setting the second texture sub-part 321 only above the first texture sub-part 311 located within the second interval sub-region 222, on the one hand, the second texture sub-layer 320 can reduce the obstruction of light from the light-emitting device 210 in a single pixel unit 200a by the second texture sub-layer 320, thus ensuring the light emission effect of the display panel 10. On the other hand, it can isolate two adjacent pixel units 200a, thereby reducing the risk of crosstalk in the display screen of the display panel 10.
