[0043] In order for those skilled in the art to better understand the solutions of the present application, the present application is further described in detail below in conjunction with the embodiments and drawings. The following specific embodiments are only used to describe the principles and characteristics of the present application, and the examples are used to explain the present application, but not to limit the scope of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] In the description of the present application, the terms "first", "second", "third", "fourth" and the like are only used for description purposes, for example, to distinguish components, so as to make the technical solutions clearer / explained, and cannot be understood as indicating or implying the number of the indicated technical features or having a substantial meaning of the order, etc.

[0045] The OLED of the embodiments of the present application can specifically include an active-matrix organic light emitting diode (AMOLED). Hereinafter, the solutions of the embodiments of the present application are specifically described by taking an AMOLED display panel as an example.

[0046] The COE (Color Filter on Encapsulation) technology is to coat a color filter (CF) after the completion of the encapsulation of the traditional AMOLED. The light emitting layer of the AMOLED usually has multiple sub-pixel layers, for example, including a red (R) sub-pixel layer, a green (G) sub-pixel layer, and a blue (B) sub-pixel layer, each of which corresponds to a color filter. Two adjacent color filters are separated by a black matrix (BM), and two adjacent sub-pixel layers are separated by a pixel definition layer (PDL).

[0047] The display panel / screen formed by the COE technology has a higher transmittance in the spectral range of the light emitted by the device, which can effectively improve the light output rate of RGB and reduce the power consumption of the screen body.

[0048] However, while improving the transmittance through the color filter, the problem of high reflectivity is brought. Specifically, the color filter cannot block the external incident light from being reflected again. When the external light is incident on the display panel through the CF, it is usually reflected by the internal structure of the display panel such as the anode and then emitted out of the display panel again, which reduces the contrast of the display panel / screen and affects the display effect.

[0049] Therefore, it is urgent to reduce the reflectivity of the display panel to incident light without affecting the transmittance of the device's own self-emitting light (outgoing light).

[0050] To address the aforementioned technical problems, embodiments of the present invention provide a display panel, such as... Figure 1 As shown, the display panel includes a substrate 1, an anode 2, a light-emitting layer, an encapsulation layer 5, a touch layer 6, and a filter layer stacked sequentially. The filter layer includes a color filter (or color film). The area of ​​the encapsulation layer 5 corresponding to the color filter is used for a first light-diffusing structure to diffuse the incident light A entering the display panel. And / or, the area of ​​the touch layer 6 corresponding to the color filter has a second light-diffusing structure for diffused light A entering the display panel.

[0051] In this way, when external light enters the display panel through the color filter, it forms a diverging light path through the aforementioned light diverging structure, reducing the incident light A that hits the internal structure of the anode 2 and other reflective light sources. This reduces the reflection of the incident light, lowers the reflectivity of the display panel to the incident light A, and improves the contrast of the display panel. At the same time, it does not affect the transmittance of the device's self-emissive light, thus optimizing the display effect.

[0052] Specifically, the first light-emitting structure is a first protrusion structure facing the light-emitting layer formed in the area corresponding to the color filter of the encapsulation layer 5, such as... Figure 1 As shown, the side of the first protrusion structure facing the light-emitting layer is a first convex arc surface 50, which is equivalent to the lower surface of the first light-diverging structure forming a concave lens section, thereby realizing the divergence of the incident light A.

[0053] Furthermore, the second light-emitting structure is a second protrusion structure facing the light-emitting layer formed in the area corresponding to the touch layer 6 and the color filter, such as... Figure 1 As shown, the side of the second protrusion structure facing the light-emitting layer is a second convex arc surface 60, which is equivalent to the lower surface of the second light-diverging structure forming a concave lens section, thereby realizing the divergence of the incident light A.

[0054] Specifically, the light-emitting layer includes multiple sub-pixel layers (or light-emitting units) and a pixel definition layer 4 located on at least one side of the sub-pixel layers, with adjacent sub-pixel layers separated by the pixel definition layer 4.

[0055] Under normal circumstances, such as Figure 1 As shown, each sub-pixel layer has a pixel definition layer 4 on both sides, and each anode 2 has a pixel definition layer 4 on both sides. This means that the pixel definition layer 4 has multiple grooves, the same number as the sub-pixel layer / anode 2, and each sub-pixel layer / anode 2 is located in one groove.

[0056] For example, such as Figure 1As shown, there are three sub-pixel layers: a first sub-pixel layer 31, a second sub-pixel layer 32, and a third sub-pixel layer 33. The first sub-pixel layer 31 and the second sub-pixel layer 32 are separated by a pixel definition layer 4, and the second sub-pixel layer 32 and the third sub-pixel layer 33 are also separated by a pixel definition layer 4.

[0057] Specifically, the pixel definition layer 4 is opaque and can be black. For example, the pixel definition layer 4 is formed of a black opaque pixel definition layer material. When external light enters the display panel, it forms a diverging light path through the first protrusion structure of the encapsulation layer 5 and / or the second protrusion structure of the touch layer 6, causing more incident light A to be absorbed by the black pixel definition layer 4, thereby reducing the reflectivity of the display panel to incident light A.

[0058] The material of pixel definition layer 4 can be a conventional material for this layer in the art, such as organic negative adhesives, and there are no special restrictions on it.

[0059] Specifically, color filters can filter light passing through them, such as processing the self-emission generated by a device to improve the color purity of the emitted light.

[0060] Generally, the filter layer includes multiple color filters (i.e., the number of the aforementioned color filters is multiple). The number of color filters is the same as the number of sub-pixel layers in the light-emitting layer, with one color filter corresponding to one sub-pixel layer.

[0061] For example, such as Figure 1 As shown, there are three color filters: a first color filter 71 corresponding to the first sub-pixel layer 31, a second color filter 72 corresponding to the second sub-pixel layer 32, and a third color filter 73 corresponding to the third sub-pixel layer 33.

[0062] For example, the first sub-pixel layer 31 is a red sub-pixel layer, the first color filter 71 is a red filter, the second sub-pixel layer 32 is a green sub-pixel layer, the second color filter 72 is a green filter, the third sub-pixel layer 33 is a blue sub-pixel layer, and the third color filter 73 is a blue filter.

[0063] The red subpixel layer is used to emit red light, the green subpixel layer is used to emit green light, and the blue emitting layer is used to emit blue light. The red, green, and blue subpixel layers are formed by emitting materials that emit light of the corresponding colors, and these materials can be conventional materials for these layers in the field.

[0064] In addition, color filters can also be made of conventional materials in this field, and there are no special restrictions on this.

[0065] The filter layer further comprises a black matrix 8, two adjacent color filters are separated by the black matrix 8, and the color filters corresponding to different sub-pixel layers are separated by the black matrix 8, which can prevent color mixing, and the black matrix 8 is black and opaque, and can also block light.

[0066] As shown in the example, Figure 1 The first color filter 71 and the second color filter 72 are separated by a black matrix 8, and the second color filter 72 and the third color filter 73 are separated by a black matrix 8.

[0067] As shown in the example, Figure 1 The opposite sides of each color filter are provided with a black matrix 8.

[0068] In addition, the color filter is formed with a third light diverging structure for diverging the incident light A entering the display panel, which can be a third convex structure formed on the color filter and facing the light-emitting layer. One side of the third convex structure facing the light-emitting layer is a third convex arc surface 70, i.e., the side of the color filter facing the light-emitting layer is formed with a concave lens surface, which is beneficial to the formation of diverging light by the incident light A and further reduces the reflectivity of the display panel to the incident light A.

[0069] Generally, the refractive index of the color filter is less than the refractive index of the touch layer 6, the refractive index of the touch layer 6 is less than or substantially equal to the refractive index of the encapsulation layer 5, and correspondingly, the refractive index of the color filter is less than the refractive index of the second light diverging structure, the refractive index of the second light diverging structure is less than or substantially equal to the refractive index of the first light diverging structure, which is beneficial to the divergence of the incident light A by the first light diverging structure and the second light diverging structure, so that more incident light is absorbed by the pixel definition layer 4, and the reflectivity of the display panel to the incident light A is further reduced.

[0070] Substantially equal means that due to the existence of errors (such as operation errors), the refractive index of the touch layer 6 may not be absolutely equal to the refractive index of the encapsulation layer 5, but within the error range that can be understood by those skilled in the art, the refractive index of the touch layer 6 is considered to be equal to the refractive index of the encapsulation layer 5.

[0071] Specifically, the touch layer 6 can realize touch control and can be made of conventional processes and materials in the art, which are not particularly limited. The touch layer generally has a multi-layer structure, and the outer layer is an inorganic layer. Generally, the refractive index of the color filter is less than the refractive index of the touch layer 6, which means that the refractive index of the color filter is less than the refractive index of the inorganic layer adjacent to the color filter in the touch layer 6.

[0072] Specifically, the encapsulation layer 5 protects the light-emitting layer from water, oxygen, and other contaminants. This can be achieved using thin-film encapsulation (TFE) to form the encapsulation layer 5 (i.e., the TFE layer). The encapsulation layer typically has a multi-layered structure, with an outer inorganic layer. The refractive index of the touch layer 6 being less than or approximately equal to the refractive index of the encapsulation layer 5 generally means that the refractive index of the inorganic layer adjacent to the encapsulation layer 5 in the touch layer 6 is less than or approximately equal to the refractive index of the inorganic layer adjacent to the touch layer 6 in the encapsulation layer 5.

[0073] In some specific embodiments, the touch layer includes a first inorganic layer, a metal layer, and a second inorganic layer stacked sequentially, and the encapsulation layer includes a third inorganic layer, an organic layer, and a fourth inorganic layer stacked sequentially. The first inorganic layer is adjacent to the filter layer, the second inorganic layer is adjacent to the third inorganic layer, and the fourth inorganic layer is adjacent to the light-emitting layer. The refractive index of the color filter is less than the refractive index of the first inorganic layer, and the refractive index of the second inorganic layer is substantially equal to or less than the refractive index of the third inorganic layer.

[0074] The first inorganic layer and the second inorganic layer may be the same or different, and the third inorganic layer and the fourth inorganic layer may be the same or different. The aforementioned inorganic or organic layers may be formed from conventional materials of these layers in the art, and there are no particular restrictions on this.

[0075] In some specific embodiments, the refractive index of the color filter is 1.6 to 1.7.

[0076] In some specific embodiments, the refractive index of the first inorganic layer or the second inorganic layer of the touch layer 6 is 1.7 to 1.8.

[0077] In some specific embodiments, the refractive index of the third inorganic layer of the encapsulation layer 5 is 1.7 to 1.8.

[0078] Specifically, such as Figure 1 As shown, incident light A passes sequentially through a color filter, touch layer 6, and encapsulation layer 5. It then forms a diverging light path through the third convex arc surface 70, the second convex arc surface 60, and the first convex arc surface 50, reducing the incident light transmitted to the anode 2 and allowing more incident light A to be transmitted to the pixel definition layer 4, where it is absorbed, thus reducing the reflectivity of the display panel to incident light A.

[0079] Specifically, such as Figure 1As shown, the encapsulation layer 5 includes a first planar region and a first arcuate region (i.e., the region corresponding to the color filter of the encapsulation layer 5). The side of the first planar region facing the light-emitting layer and the side facing away from the light-emitting layer are both basically planar. The side of the first arcuate region facing the light-emitting layer is the aforementioned first convex arcuate surface 50, and the side of the first arcuate region facing away from the light-emitting layer (which is also the side facing the filter layer) is a first concave arcuate surface. This first concave arcuate surface matches the second convex arcuate surface 60 of the touch layer 6. The first concave arcuate surface is connected to the second convex arcuate surface 60 of the touch layer 6, and the first planar region is connected to the pixel definition layer 4.

[0080] In addition, the touch layer 6 includes a second planar area and a second arcuate area (i.e., the area corresponding to the touch layer 6 and the color filter). The side of the second planar area facing the light-emitting layer and the side away from the light-emitting layer are both basically planar. The side of the second arcuate area facing the light-emitting layer is the aforementioned second convex arcuate surface 60, and the side of the second arcuate area away from the light-emitting layer (which is also the side facing the filter layer) is a second concave arcuate surface. This second concave arcuate surface matches the third convex arcuate surface 70 of the color filter. The color filter is disposed on the second concave arcuate surface of the second arcuate area. The black matrix 8 is disposed on the second planar area. The second planar area is connected to one side of the first planar area of ​​the encapsulation layer 5, and the pixel definition layer 4 is connected to the other side of the first planar area of ​​the encapsulation layer 5.

[0081] Specifically, the number of the first curved surface area of ​​the encapsulation layer 5 and the number of the second curved surface area of ​​the touch layer 6 are the same as the number of sub-pixel layers of the color filter / light-emitting layer, and they correspond one-to-one. That is, each sub-pixel layer has a corresponding first curved surface area, second curved surface area and color filter.

[0082] Under normal circumstances, the projections of the third convex arc surface 70 of the color filter, the second convex arc surface 60 / second arc surface area of ​​the touch layer 6, and the first convex arc surface 50 / first arc surface area of ​​the encapsulation layer 5 onto the substrate 1 cover the projections of the corresponding sub-pixel layers onto the substrate 1.

[0083] In some embodiments, such as Figure 1 As shown, the filter layer also includes a light-reflecting layer 9 disposed on the side of the black matrix 8 facing the color filter. In this way, the self-emitted light (emitted light B) generated by the light-emitting layer is transmitted through the encapsulation layer 5, the touch layer 6 and the color filter in sequence. During this process, the emitted light B is refracted by the convex arc surface of the encapsulation layer 5, the touch layer 6 and the lower surface of the color filter. At least part of the light hits the light-reflecting layer 9 and is reflected by the light-reflecting layer 9, which increases the proportion of light emitted at the positive viewing angle, thereby improving the self-emitted transmittance of the device.

[0084] Thus, by adjusting the light path of the incident light and the outgoing light B through the convex arc surface and the light reflection layer 9, the reflectivity of the external incident light A and the transmittance of the self-emitting light of the device can be considered, and the problem that the reflectivity of the external incident light A and the transmittance of the self-emitting light of the device cannot be considered in the related art can be overcome.

[0085] The refractive index of the light reflection layer 9 is less than the refractive index of the color filter, which is conducive to total reflection of the outgoing light B hitting the light reflection layer 9, and increases the light emission proportion.

[0086] Specifically, the refractive index of the light reflection layer 9 can be 1.4-1.5, which can be formed by conventional materials in the art, such as organic positive glue and the like.

[0087] Generally, the light reflection layer 9 is an inclined film layer, that is, the light reflection layer 9 is inclined relative to the second planar region of the touch layer 6. According to the research of the inventor, the normal angle light emission proportion is reduced due to the refraction of the self-emitting light of the device through the encapsulation layer, the touch layer and the lower surface of the color filter in sequence. However, after the light reflection layer 9 is arranged, part of the light is refracted through the lower surface of the color filter and hits the surface of the light reflection layer 9. Since the light reflection layer 9 is an inclined film layer, the angle is large, and the refractive index of the light reflection layer is less than the refractive index of the color filter, so that the part of the light is totally reflected, thereby increasing the light emission proportion.

[0088] In some preferred embodiments, an included angle a is formed between the light reflection layer 9 and the second planar region of the touch layer 6, 60°≤a≤80°, that is, the inclination angle of the light reflection layer 9 is a, and a is controlled within the above range, which is conducive to further increasing the light emission proportion and improving the transmittance of the self-emitting light of the device.

[0089] In some specific embodiments, the pixel definition layer 4 is black, the region of the encapsulation layer 5 corresponding to the color filter is formed with a first protruding structure facing the light-emitting layer, the region of the touch layer 6 corresponding to the color filter is formed with a second protruding structure facing the light-emitting layer, the color filter is formed with a third protruding structure facing the light-emitting layer, the refractive index of the light reflection layer 9 is less than the refractive index of the color filter, the refractive index of the color filter is less than the refractive index of the first inorganic layer of the touch layer 6, and the refractive index of the second inorganic layer of the touch layer 6 is less than or substantially equal to the refractive index of the third inorganic layer of the encapsulation layer 5. In this way, on the one hand, the external incident light A forms an emission light path through the color filter, the touch layer 6 and the lower surface of the encapsulation layer 5 in sequence, so that the external incident light hits the black pixel definition layer 4 and is absorbed, thereby reducing the reflectivity; on the other hand, at least part of the light of the self-emitting light of the device hits the surface of the light reflection layer after the lower surface of the color filter, and the refractive index of the light reflection layer is less than the refractive index of the color filter, so that the part of the light is totally reflected, thereby increasing the light emission proportion. Thus, the reflectivity of the external incident light and the light emission rate of the self-emitting light can be considered, and the display effect can be improved.

[0090] Specifically, the black matrix 8 is located in the second plane area of ​​the touch layer 6. The side of the black matrix 8 facing the touch layer 6 (which is also the side facing the light-emitting layer) is a plane that is adapted to the surface of the second plane area. The angle between the side of the black matrix 8 facing the color filter and the side of the black matrix 8 facing the light-emitting layer is also basically equal to α.

[0091] For example, such as Figure 1 As shown, the shape of the black matrix 8 is trapezoidal, specifically a regular trapezoid, that is, wider at the top and narrower at the bottom. The side length of the black matrix 8 facing away from the light-emitting layer is smaller than the side length of the black matrix 8 facing the light-emitting layer, but it is not limited to this.

[0092] Specifically, the side of the black matrix 8 facing the color filter is basically flat, and correspondingly, the side of the light-reflecting layer 9 that contacts the black matrix 8 is also flat.

[0093] Typically, the light-reflecting layer 9 covers the side of the black matrix 8 facing the color filter. Specifically, as shown below... Figure 1 As shown, the side of the light-reflecting layer 9 facing away from the light-emitting layer is basically flush with the side of the black matrix 8 facing away from the light-emitting layer, and the side of the light-reflecting layer 9 facing the light-emitting layer is basically flush with the side of the black matrix 8 facing the light-emitting layer, so that the side of the black matrix 8 facing the color filter is completely covered by the light-reflecting layer 9.

[0094] Furthermore, the side of the light-reflecting layer 9 that faces away from the black matrix 8 (which is also the side facing the color filter) can be a plane.

[0095] In addition, the thickness of the light-reflecting layer 9 can generally be 1~2μm.

[0096] like Figure 1 As shown, the side of the color filter facing away from the light-emitting layer is a fourth convex arc surface 700, which facilitates the multi-angle divergence of the emitted light B and ensures uniform light output.

[0097] Normally, a first extension portion 701 is formed on the side of the color filter opposite to the light-emitting layer, extending to the side of the black matrix 8 opposite to the light-emitting layer.

[0098] Specifically, such as Figure 1 As shown, the first epitaxial portion 701 extends to the side of the black matrix 8 opposite to the light-emitting layer and contacts the side of the black matrix 8 opposite to the light-emitting layer, covering the light-reflecting layer 9.

[0099] In addition, such as Figure 1 As shown, the color filter has a second extension portion 702 on the side facing the light-emitting layer. The second extension portion 702 extends to the side of the light-reflecting layer 9 facing the light-emitting layer and contacts the side of the light-reflecting layer 9 facing the light-emitting layer, but is not limited thereto.

[0100] Specifically, the second epitaxial part 702 is located at the second curved surface area of the touch layer 6, and the side of the second epitaxial part 702 facing the filter layer is substantially flush with the side of the second planar area of the touch layer 6 facing the filter layer.

[0101] In addition, as shown in Figure 1 The number of the anodes 2 can be multiple, same as the number of the sub-pixel layers, and one-to-one corresponding, that is, each sub-pixel layer corresponds to one anode 2. The adjacent two anodes 2 are spaced apart by the pixel defining layer 4.

[0102] Specifically, the anode material can include at least one of indium tin oxide (ITO), indium zinc oxide (IZO), tin dioxide (SnO2), zinc oxide (ZnO), and other oxide transparent conductive materials.

[0103] In addition, the substrate 1 can specifically include a substrate with a thin film transistor (TFT) (i.e., a TFT substrate).

[0104] In a specific embodiment, the manufacturing method of the display panel can include: forming a first recess at a predetermined position of the light-emitting layer, then forming an encapsulation layer on the light-emitting layer, and the area of the formed encapsulation layer corresponding to the first recess forms a first convex structure; forming a second recess at a predetermined position on the side of the encapsulation layer away from the light-emitting layer, then forming a touch layer on the encapsulation layer, and the area of the formed touch layer corresponding to the second recess forms a second convex structure; forming a third recess at a predetermined position on the side of the touch layer away from the light-emitting layer, then forming a light shielding layer on the touch layer, and the color filter of the formed light shielding layer corresponds to the third recess, so that the side of the color filter facing the light-emitting layer forms a third convex structure matched with the third recess.

[0105] Specifically, the recesses (the first recess, the second recess, or the third recess) of the above-mentioned layers can be formed by etching, but are not limited thereto, and can also be formed by other feasible processes, and the present application does not make special limitations thereon.

[0106] In addition, each layer described above can be formed by deposition, coating, evaporation, etc. in a conventional manner in the art.
