Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] like Figure 1 and Figure 2 As shown, a display panel provided in the first aspect embodiment of this application includes: a substrate 100, a texture layer 200, and a light-emitting unit 300; the texture layer 200 is disposed on one side of the substrate 100, and the texture layer 200 includes a texture portion 210 and a cutout opening 220 formed on the texture portion 210; the light-emitting unit 300 is disposed on one side of the substrate 100, and the orthographic projection of the light-emitting unit 300 on the substrate 100 is located within the orthographic projection of the cutout opening 220 on the substrate 100; wherein, at least a portion of the texture portion 210 is disposed on the side of the light-emitting unit 300 away from the substrate 100, and the texture portion 210 includes at least two texture blocks of different colors stacked along the thickness direction Z of the substrate 100.

[0055] In this embodiment, the orthographic projection of the light-emitting unit 300 onto the substrate 100 lies within the orthographic projection of the cutout opening 220 onto the substrate 100. The cutout opening 220 allows the emitted light from the light-emitting unit 300 to pass through, thereby reducing the obstruction of the emitted light by the texture layer 200. The texture section 210 includes at least two texture blocks of different colors stacked along the thickness direction Z of the substrate 100. The orthographic projections of the at least two texture blocks on the substrate 100 at least partially overlap. The texture blocks include a light-transmitting material. The stacking of at least two texture blocks of different colors forms a display panel with a colored texture effect, thereby improving the performance of the display panel.

[0056] Optional, such as Figure 2 As shown, the display panel includes a pixel definition layer, which includes a pixel limiting portion 700 and a pixel opening 214 formed by the pixel limiting portion 700. The light-emitting unit 300 is located inside the pixel opening 214, and the texture portion 210 is located on the side of the pixel limiting portion 700 away from the substrate 100, thereby reducing the influence of the texture portion 210 on the light emission of the light-emitting unit 300 and reducing the influence of the texture portion 210 on the brightness of the display panel.

[0057] like Figure 2 As shown, in some optional embodiments, the display panel further includes a second texture layer 202 located on the side of the light-emitting unit 300 away from the substrate 100. The texture portion 210 includes a second texture portion 212 located in the second texture layer 202. The cutout opening 220 includes a first light-transmitting opening 215 formed by the second texture portion 212. The orthographic projection of the first light-transmitting opening 215 on the substrate 100 at least partially overlaps with the orthographic projection of the light-emitting unit 300 on the substrate 100.

[0058] In these optional embodiments, the second texture layer 202 is located on the side of the light-emitting unit 300 facing away from the substrate 100. The second texture portion 212 surrounds and forms a first light-passing port 215. The orthographic projection of the first light-passing port 215 onto the substrate 100 at least partially overlaps with the orthographic projection of the light-emitting unit 300 onto the substrate 100, thereby allowing the emitted light from the light-emitting unit 300 to pass through the first light-passing port 215. Since the second texture portion 212 is not disposed above the light-emitting unit 300, the second texture portion 212 does not reduce the brightness of the screen. The second texture portion 212 includes at least two texture blocks of different colors stacked together, thereby forming a display panel with a color texture effect.

[0059] Optional, such as Figure 2 As shown, the second textured portion 212 surrounds and forms each first light-transmitting port 215. The spacing between two adjacent first light-transmitting ports 215 ranges from 3 micrometers to 10 micrometers. Specifically, the spacing between each first light-transmitting port 215 can be 3 micrometers, 4 micrometers, 5 micrometers, 8 micrometers, 10 micrometers, etc.

[0060] Optional, such as Figure 2 As shown, the display panel also includes a first encapsulation layer 510, which is disposed on the side of the second texture layer 202 facing the substrate 100. The first encapsulation layer 510 is disposed on the side of the light-emitting unit 300 away from the substrate 100. The first encapsulation layer 510 is used to encapsulate the light-emitting unit 300, reduce damage to the light-emitting unit 300 in subsequent processes, and at the same time prevent water, oxygen, etc. from entering the light-emitting unit 300 and causing damage.

[0061] Optional, such as Figure 2 As shown, a second encapsulation layer 520 is also provided on the side of the second textured portion 212 away from the substrate 100. The second encapsulation layer 520 can reduce the damage to the second textured portion 212 in subsequent processes.

[0062] Optionally, the second encapsulation layer 520 may include an organic material.

[0063] Optional, such as Figure 2 As shown, an inorganic encapsulation layer 530 is disposed between the second texture layer 202 and the second encapsulation layer 520. The inorganic encapsulation layer 530 covers the second texture portion 212 and the first light-transmitting port 215. Since the second encapsulation layer 520 includes organic materials, in order to reduce the mutual solubility of ink and organic materials in the second texture portion 212, an inorganic encapsulation layer 530 is disposed between the second texture layer 202 and the second encapsulation layer 520, thereby reducing the mutual solubility of ink and second encapsulation layer 520 in the second texture portion 212.

[0064] Optional, such as Figure 2 As shown, an inorganic encapsulation layer 530 is provided on the surface of the second textured portion 212 facing the second encapsulation layer 520. Unlike the above embodiment, the inorganic encapsulation layer 530 may be provided only on the surface of the second textured portion 212 facing the second encapsulation layer 520, thereby reducing the mutual solubility of ink in the second textured portion 212 with the second encapsulation layer 520.

[0065] Optionally, the thickness of the inorganic encapsulation layer 530 can be between 0.2 micrometers and 1 micrometer, specifically 0.2 micrometers, 0.4 micrometers, 0.6 micrometers, and 1 micrometer. The material of the inorganic encapsulation layer 530 can include SiN, SiOX, SiON, etc.

[0066] like Figure 3 As shown, in some optional embodiments, the display panel further includes a third texture layer 203, which is disposed on the side of the second texture layer 202 away from the substrate 100; the texture portion 210 includes a third texture portion 213 located in the third texture layer 203, and the cutout opening 220 includes a second light-transmitting opening 216 formed by the third texture portion 213, and the orthographic projection of the second light-transmitting opening 216 on the substrate 100 at least partially overlaps with the orthographic projection of the light-emitting unit 300 on the substrate 100.

[0067] In these optional embodiments, the third texture layer 203 is disposed on the side of the second texture layer 202 facing away from the substrate 100, and the third texture portion 213 is disposed on the side of the second texture portion 212 facing away from the substrate 100. The orthographic projection of the second light-transmitting port 216 onto the substrate 100 at least partially overlaps with the orthographic projection of the light-emitting unit 300 onto the substrate 100, thereby allowing the emitted light from the light-emitting unit 300 to pass through the second light-transmitting port 216. Since the third texture portion 213 is not disposed above the light-emitting unit 300, the third texture portion 213 does not reduce the brightness of the screen. The third texture portion 213 includes at least two texture blocks of different colors stacked together, thereby forming a display panel with a color texture effect.

[0068] Optional, such as Figure 3 As shown, the orthographic projection of the first light-transmitting port 215 onto the substrate 100 is located within the orthographic projection of the second light-transmitting port 216 onto the substrate 100. The opening area of ​​the second light-transmitting port 216 is greater than or equal to the opening area of ​​the first light-transmitting port 215, thereby reducing the obstruction of the second texture portion 212 by the third texture portion 213. The second texture portion 212 and the third texture portion 213 combine to form the texture effect of the display panel.

[0069] Optional, such as Figure 3 As shown, the orthographic projection of the third texture portion 213 onto the substrate 100 is located within the orthographic projection of the second texture portion 212 onto the substrate 100, thereby allowing part of the second texture portion 212 to be exposed beyond the edge of the third texture portion 213, reducing the occlusion of the second texture portion 212 by the third texture portion 213. The combination of the second texture portion 212 and the third texture portion 213 achieves the texture effect.

[0070] Optional, such as Figure 3 As shown, the third texture portion 213 surrounds and forms each second light-transmitting port 216. The spacing between two adjacent second light-transmitting ports 216 ranges from 3 micrometers to 6 micrometers. Specifically, the spacing between each second light-transmitting port 216 can be 3 micrometers, 4 micrometers, 5 micrometers, 6 micrometers, etc.

[0071] Optional, such as Figure 3 As shown, the third texture layer 203 is disposed on the side of the second encapsulation layer 520 away from the substrate 100. After the second texture layer 202 is encapsulated by the second encapsulation layer 520, the third texture layer 203 is then fabricated.

[0072] Optional, such as Figure 3As shown, a third encapsulation layer 540 is further disposed between the third texture portion 213 and the second encapsulation layer 520. Since the second encapsulation layer 520 includes organic materials, the ink particles of the third texture portion 213 will be mutually soluble with the organic materials. The third encapsulation layer 540, which includes inorganic materials, is further disposed between the third texture portion 213 and the second encapsulation layer 520.

[0073] Optional, such as Figure 3 As shown, the display panel also includes a fill layer 550, which is located on the side of the third textured portion 213 away from the substrate, and the fill layer 550 fills the second light-transmitting port 216 to planarize the third textured layer 203.

[0074] like Figure 4 As shown, in some optional embodiments, the texture layer 200 includes a first texture layer 201, the texture portion 210 includes a first texture portion 211 located in the first texture layer 201, the cutout opening 220 includes a pixel opening 214 formed by the first texture portion 211, and the light-emitting unit 300 is located within the pixel opening 214.

[0075] In these optional embodiments, the texture layer 200 includes a first texture layer 201 located on one side of the substrate 100. The texture portion 210 includes a first texture portion 211 located on the first texture layer 201. The first texture portion 211 surrounds and forms a pixel opening 214, and the light-emitting unit 300 is located within the pixel opening 214. In some embodiments, the pixel limiting portion 700 reduces light crosstalk between the light-emitting units 300. In this application, the first texture portion 211 replaces the pixel limiting portion 700. The first texture portion 211 surrounds and forms the pixel opening 214, and the light-emitting unit 300 is located within the pixel opening 214. The first texture portion 211 reduces electronic and light crosstalk between adjacent light-emitting units 300. The first texture portion 211 includes at least two texture blocks of different colors stacked together, thereby forming a display panel with a color texture effect. The first texture section 211 is disposed between adjacent light-emitting units 300. The emitted light from the light-emitting unit 300 is emitted directly through the pixel opening 214, thereby reducing the influence of the first texture section 211 on the emitted light of the light-emitting unit 300.

[0076] The first texture portion 211 surrounds and forms a pixel opening 214, and a light-emitting unit 300 is formed within the pixel opening 214. Since the first texture portion 211 is formed before the light-emitting unit 300, the first texture portion 211 can be formed through a high-temperature process, thus avoiding damage to the light-emitting unit 300 caused by the high-temperature process.

[0077] Optional, such as Figure 4As shown, the first texture portion 211 surrounds and forms the pixel openings 214. The spacing between two adjacent pixel openings 214 ranges from 3 micrometers to 20 micrometers. Specifically, the spacing between each pixel opening can be 3 micrometers, 4 micrometers, 5 micrometers, 8 micrometers, 10 micrometers, 12 micrometers, 15 micrometers, 18 micrometers, 20 micrometers, etc.

[0078] Optional, such as Figure 4 As shown, the first encapsulation layer 510 is also disposed between the first textured portion 211 and the second textured portion 212. The first encapsulation layer 510 can reduce the damage to the first textured portion 211 caused by subsequent processes.

[0079] Optional, such as Figure 4 As shown, at least one of the first textured portion, the second textured portion, and the third textured portion has a dimension of 1 micrometer to 4 micrometers along the thickness direction of the substrate. Specifically, it can be 1 micrometer, 1.5 micrometers, 2 micrometers, 2.5 micrometers, 3 micrometers, 3.5 micrometers, 4 micrometers, etc.

[0080] Optional, such as Figure 4 As shown, the first texture block 410 is black, and the first texture portion 211 includes the first texture block 410 and at least one of a second texture block 420, a third texture block 430, and a fourth texture block 440 located on the side of the first texture block 410 facing away from the substrate 100. The black color of the first texture block 410 can block some of the reflected light from the metal material or light-reflecting material in the driving circuit layer, thereby improving the display effect of the display panel. The black color of the first texture block 410, with at least one of the second texture block 420, the third texture block 430, and the fourth texture block 440 facing the substrate 100, prevents the first texture block 410 from blocking at least one of the second texture block 420, the third texture block 430, and the fourth texture block 440.

[0081] Optional, such as Figure 4 As shown, the orthographic projection of the second texture portion 212 onto the substrate 100 at least partially overlaps with the orthographic projection of the first texture portion 211 onto the substrate 100, thereby combining the first texture portion 211 and the second texture portion 212 to produce the texture effect of the display panel.

[0082] Optional, such as Figure 4 As shown, the orthographic projection of the pixel opening 214 onto the substrate 100 is located within the orthographic projection of the first light-transmitting port 215 onto the substrate 100; the opening area of ​​the first light-transmitting port 215 is greater than or equal to the opening area of ​​the pixel opening 214, thereby reducing the influence of the second texture portion 212 on the light emitted by the light-emitting unit 300 within the pixel opening 214.

[0083] Optional, such as Figure 4As shown, the orthographic projection of the second texture portion 212 onto the substrate 100 lies within the orthographic projection of the first texture portion 211 onto the substrate 100. This allows a portion of the first texture portion 211 to be exposed beyond the edge of the second texture portion 212, reducing the occlusion of the first texture portion 211 by the second texture portion 212. The combination of the first texture portion 211 and the second texture portion 212 achieves the texture effect. The light-emitting unit 300 is located within the pixel opening 214 formed by the first texture portion 211. The fact that the orthographic projection of the second texture portion 212 onto the substrate 100 lies within the orthographic projection of the first texture portion 211 onto the substrate 100 reduces the influence of the second texture portion 212 on the large-angle light emission of the light-emitting unit 300.

[0084] Optional, such as Figure 4 As shown, the orthographic projection of the third texture portion 213 onto the substrate 100 at least partially overlaps with the orthographic projection of the first texture portion 211 onto the substrate 100, thereby combining the first texture portion 211 and the third texture portion 213 to produce the texture effect of the display panel.

[0085] Optional, such as Figure 4 As shown, the orthographic projection of the pixel opening 214 onto the substrate 100 is located within the orthographic projection of the second light-transmitting port 216 and / or the first light-transmitting port 215 onto the substrate 100. The opening area of ​​the second light-transmitting port 216 and / or the first light-transmitting port 215 is greater than or equal to the opening area of ​​the pixel opening 214, thereby reducing the influence of the third texture portion 213 and / or the second texture portion 212 on the light emitted by the light-emitting unit 300 within the pixel opening 214.

[0086] Optional, such as Figure 4 As shown, the orthographic projection of the third texture portion 213 onto the substrate 100 lies within the orthographic projection of the first texture portion 211 onto the substrate 100. This allows a portion of the first texture portion 211 to be exposed beyond the edge of the third texture portion 213, reducing the occlusion of the first texture portion 211 by the third texture portion 213. The combination of the first texture portion 211 and the third texture portion 213 achieves the texture effect. The light-emitting unit 300 is located within the pixel opening 214 formed by the first texture portion 211. The orthographic projection of the third texture portion 213 onto the substrate 100, lying within the orthographic projection of the first texture portion 211 onto the substrate 100, reduces the influence of the second texture portion 212 on the large-angle light emission of the light-emitting unit 300.

[0087] like Figure 4 As shown, in some optional embodiments, along the direction away from the substrate 100, the cross-sectional area of ​​the textured portion 210 gradually decreases along the Z direction perpendicular to the thickness of the substrate 100.

[0088] In these optional embodiments, the texture portion 210 is disposed around the hollow opening 220. Along the direction away from the substrate 100, the cross-sectional area of ​​the texture portion 210 gradually decreases along the Z direction perpendicular to the thickness of the substrate 100, thereby reducing the interference of the texture portion 210 on the large-angle emitted light of the light-emitting unit 300 and improving the display effect of the display panel.

[0089] like Figure 4 As shown, in some optional embodiments, the light-emitting unit 300 includes a first electrode 301, a light-emitting structure 302, and a second electrode 303 arranged sequentially along the direction away from the substrate 100. The first electrode 301 extends from the pixel opening 214 to the side of the first texture portion 211 facing the substrate 100, and the second electrode 303 extends from the pixel opening 214 to the side of the first texture portion 211 away from the substrate 100.

[0090] In these optional embodiments, the first electrode 301 extends from the pixel opening 214 to the side of the first texture portion 211 facing the substrate 100, the pixel opening 214 exposes part of the first electrode 301, the light-emitting structure 302 is located inside the pixel opening 214, and the second electrode 303 extends from the pixel opening 214 to the side of the first texture portion 211 away from the substrate 100, so as to realize that the second electrodes 303 of each light-emitting unit 300 are electrically connected to each other.

[0091] like Figure 5 As shown, in some optional embodiments, the display panel further includes a protrusion structure 600, which is disposed between the first electrode 301 and the substrate 100. The orthographic projection of the protrusion structure 600 on the substrate 100 at least partially overlaps with the orthographic projection of the pixel opening 214 on the substrate 100. The protrusion structure 600 includes a plurality of protrusions 610, which are protruding in a direction away from the substrate 100, so that the light-emitting unit 300 is protruding in a direction away from the substrate 100.

[0092] In these optional embodiments, a protrusion structure 600 is disposed between the first electrode 301 and the substrate 100. The protrusion structure 600 includes a plurality of protrusions 610, which are formed to protrude in a direction away from the substrate 100. When the first electrode 301 is formed on the protrusion 610, the first electrode 301 covers the protrusion 610 to form a protrusion. When the light-emitting structure 302 is formed on the first electrode 301, the light-emitting structure 302 covers the first electrode 301 to form a protrusion. A second electrode 303 is formed on the light-emitting structure 302, and the second electrode 303 covers the light-emitting structure 302 to form a protrusion. This causes the light-emitting unit 300 to protrude in a direction away from the substrate 100, thereby improving the large-angle light emission of the light-emitting unit 300, making the light emission angles of the display panel more uniform, and reducing the viewing angle distortion of the display.

[0093] Optional, such as Figure 5 As shown, the display panel also includes a planarization layer 110, which is disposed between the substrate 100 and the first textured portion 211 and the light-emitting unit 300. The planarization layer 110 is connected to the protrusion 610 and is made of the same material. The planarization layer 110 is used to planarize the side of the substrate 100 facing the light-emitting unit 300. The planarization layer 110 is connected to the protrusion 610 and is made of the same material, so that the planarization layer 110 and the protrusion 610 can be formed simultaneously in the same manufacturing process.

[0094] Optionally, the material of the protrusion 610 may include polyimide.

[0095] Optionally, the size of the protrusion 610 along the Z direction perpendicular to the thickness of the substrate 100 is 2 micrometers to 30 micrometers, specifically 2 micrometers, 3 micrometers, 5 micrometers, 8 micrometers, 10 micrometers, 12 micrometers, 15 micrometers, 18 micrometers, 20 micrometers, 22 micrometers, 25 micrometers, 28 micrometers, 30 micrometers, etc.

[0096] Optionally, the size of the protrusion 610 along the thickness direction Z of the substrate 100 is from 0.5 micrometers to 2 micrometers. Specifically, it can be 0.5 micrometers, 0.8 micrometers, 1 micrometer, 1.2 micrometers, 1.5 micrometers, 1.8 micrometers, 2 micrometers, etc.

[0098] In these optional embodiments, the first texture block 410, the second texture block 420, the third texture block 430, and the fourth texture block 440 all include ink particles. The ink particles of the first texture block 410, the second texture block 420, the third texture block 430, and the fourth texture block 440 have different colors, thus making the first texture block 410, the second texture block 420, the third texture block 430, and the fourth texture block 440 appear in different colors. The texture portion 210 includes at least two of the first texture block 410, the second texture block 420, the third texture block 430, and the fourth texture block 440. For example, the texture portion 210 includes the second texture block 420 and the third texture block 430, which have different colors. The second texture block 420 and the third texture block 430 are stacked to display another color that is different from the colors of the second texture block 420 and the third texture block 430.

[0099] like Figure 4As shown, optionally, the first texture block 410 is black, the second texture block 420 is yellow, the third texture block 430 is magenta, and the fourth texture block 440 is cyan. Magenta plus yellow will form red; magenta plus cyan will form blue; cyan plus yellow will form green. Setting the first texture block 410 to black can improve the light-blocking property of the texture section 210 and improve the color purity of the texture section 210.

Optionally, in two adjacent texture blocks, the orthographic projection of the texture block relatively farther from the substrate 100 onto the substrate 100 lies within the orthographic projection of the texture block relatively closer to the substrate 100 onto the substrate 100.
