[0052] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0053] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0054] The inventors have found that the reasons for light leakage in the border area of the existing display panel are: Figure 1 This is a schematic diagram of the structure of a display panel in the related art, refer to Figure 1 The display panel includes a display area AA and a non-display area. The non-display area includes a frame area BA surrounding the display area AA. There is a boundary line FA between the frame area BA and the display area AA. The frame area BA includes an ink layer 110. Since the manufacturing precision of the ink layer 110 is not high, it is impossible to apply the ink to the boundary line FA between the display area AA and the frame area BA, resulting in a certain distance between the ink layer 110 and the display area AA near the boundary of the display area AA, which is about 50μm, causing the area in the frame area BA that is not coated with ink to leak light. In addition, since the manufacturing precision of the ink layer 110 is not high, a wider frame area BA needs to be reserved for coating the ink, which increases the size of the frame area BA of the display panel.
[0055] The present embodiment provides a display panel, which can improve the light leakage problem in the frame area of the display panel and enable the display panel to have a narrower frame.
[0056] Figure 2 is a schematic structural diagram of a display panel provided according to an embodiment of the present invention, Figure 3 is a schematic structural diagram of another display panel provided according to an embodiment of the present invention, Figure 4 is a schematic structural diagram of another display panel provided according to an embodiment of the present invention, Figure 5 is a schematic diagram of the structure of another display panel provided according to an embodiment of the present invention, referring to Figure 2 to Figure 5 The display panel provided in this embodiment includes: a display area AA and a non-display area NAA; the non-display area NAA includes a border area BA; the border area BA surrounds the display area AA; the display panel also includes an array substrate 210, a light-emitting structure layer 220 and a touch layer 240; the light-emitting structure layer 220 is located on one side of the array substrate 210; the touch layer 240 is located on the side of the light-emitting structure layer 220 away from the array substrate 210; the array substrate 210 includes at least one first insulating layer 214, the touch layer 240 includes a second insulating layer 241, at least one of the first insulating layer 214 and the second insulating layer 241 is a light-shielding layer 215, and the light-shielding layer 215 extends from the display area AA to the border area BA.
[0057] Specifically, the light emitting structure layer 220 includes a plurality of light emitting units 221 of different light emitting colors, and the light emitting unit 221 can emit red light, green light or blue light. The light emitting unit 221 includes a first electrode 222, a light emitting functional layer 223 and a second electrode 224 which are sequentially stacked, one of the first electrode 222 and the second electrode 224 is an anode, and the other is a cathode. The first electrode 222 of each light emitting unit 221 is arranged at intervals, and the second electrode 224 of each light emitting unit 221 can be connected as a whole or arranged at intervals. Specifically, the first electrode 222 can be the anode of the light emitting unit 221, and the second electrode 224 can be the cathode of the light emitting unit 221. The first electrode 222, i.e., the anode, is a reflective electrode, i.e., an opaque electrode. The anode can adopt a three-layer structure, wherein the first layer and the third layer can be metal oxide layers, such as indium tin oxide (ITO), indium zinc oxide (IZO), aluminum zinc oxide (AZO), and the second layer in the middle can be a metal layer (such as silver or copper). The cathode can be an ITO transparent electrode or a magnesium-silver alloy. The light-emitting functional layer 223 may include only a single film layer, that is, only a light-emitting material layer; or it may include a multilayer structure formed by a hole injection layer, a hole transport layer, a light-emitting material layer, an electron transport layer, an electron injection layer, etc. stacked from the first electrode 222 to the second electrode 224.
[0058] The light shielding layer 215 can be a black film layer, or a film layer close to black. The light shielding layer 215 has a light shielding function. The light shielding layer 215 is extended from the display area AA to the frame area BA, so that the frame area BA includes the light shielding layer 215, thereby improving the light shielding effect of the frame area BA. The light shielding layer 215 extends from the display area AA to the frame area BA, and the light shielding layer 215 can be extended from the display area AA to part of the frame area BA, or the light shielding layer 215 can be extended from the display area AA to the border of the frame area BA away from the display area AA, that is, the light shielding layer 215 fully covers the frame area BA. The area in the frame area BA that is not covered by the light shielding layer 215 can be coated with black ink. There is a boundary line FA between the frame area BA and the display area AA, and the boundary line FA is also the boundary of the display area AA. In this embodiment, the light shielding layer 215 is arranged to extend from the display area AA to the frame area BA, so that the light shielding layer 215 can be arranged on both sides of the boundary line FA, which can further improve the light shielding effect of the light shielding layer 215.
[0059] The array substrate 210 includes a substrate 216, a driving array layer 211 and a pixel definition layer 212. The material of the substrate 216 can be a flexible material, such as a polyimide matrix doped with carbon nano-reinforcements, which has good anti-curling and anti-cracking properties. The material of the substrate 216 can also be glass. Glass has good transparency and chemical stability and can provide a clear display effect. The driving array layer 211 may include a plurality of pixel driving circuits. The pixel driving circuit may be a 7T1C circuit or a 2T1C circuit. The pixel definition layer 212 may be made of organic materials such as acrylic organic compounds, polyamide, or polyimide, or inorganic materials such as silicon oxide, silicon nitride, silicon oxynitride, or aluminum oxide. The array substrate 210 may also include a support column layer 213 (see Figure 4 ), the support column layer 213 is located between the pixel definition layer 212 and the light emitting structure layer 220. The array substrate 210 may include at least two first insulating layers 214, one of which is the pixel definition layer 212, and the other is the support column layer 213.
[0060] At least one of the first insulating layer 214 and the second insulating layer 241 is a light shielding layer 215. Specifically, only the first insulating layer 214 is a light shielding layer 215 (see Figure 3 and Figure 4 ), or only the second insulating layer 241 is the light shielding layer 215 (refer to Figure 5 ), or the first insulating layer 214 and the second insulating layer 241 are both light shielding layers 215 (refer to Figure 6). When the first insulating layer 214 and the second insulating layer 241 are both light shielding layers 215, the frame area BA includes at least two layers of light shielding layers 215, which increases the optical density (OD value) of the frame area BA and further improves the light shielding effect of the frame area BA of the display panel. When the first insulating layer 214 and the second insulating layer 241 are both light shielding layers 215, in the frame area BA, the vertical projection of the first insulating layer 214 on the substrate 216 can overlap with the vertical projection of the second insulating layer 241 on the substrate 216 (see Figure 6 ). The vertical projection of the first insulating layer 214 on the substrate 216 may not overlap with the vertical projection of the second insulating layer 241 on the substrate 216. For example, the first insulating layer 214 may cover part of the border area BA, and the second insulating layer 241 may fully cover the border area BA. Alternatively, the first insulating layer 214 may fully cover the border area BA, and the second insulating layer 241 may cover part of the border area BA.
[0061] The present embodiment provides a display panel, which includes an array substrate, a light emitting structure layer and a touch layer, wherein the light emitting structure layer is located on one side of the array substrate, and the touch layer is located on the side of the light emitting structure layer away from the array substrate. The array substrate includes at least one first insulating layer, the touch layer includes a second insulating layer, at least one of the first insulating layer and the second insulating layer is a light shielding layer, and the light shielding layer extends from the display area to the frame area. The light shielding layer provided in the present embodiment has a light shielding function, and the light shielding layer provided in the frame area can block the light in the display area from being emitted from the frame area, thereby improving the problem of light leakage in the frame area. The light shielding layer is provided to extend from the display area to the frame area, that is, the light shielding layer is continuous and has no gap on both sides of the boundary line between the display area and the frame area, which can further improve the light shielding effect. At least one of the first insulating layer and the second insulating layer is a light shielding layer, and the light shielding layer is a film layer extending from the display area, not a newly added film layer. While improving the light leakage problem, the preparation process of the display panel is not increased, and the light shielding layer replaces the ink layer in the existing display panel, and there is no need to reserve a large position in the frame area to lay the ink, which can reduce the size of the frame area. It can be seen that the display panel provided in this embodiment can improve the light leakage problem in the frame area of the display panel and can also reduce the frame of the display panel.
[0062] Optional, continue to refer to Figure 6 , the array substrate 210 includes a pixel definition layer 212 ; the pixel definition layer 212 surrounds and forms a plurality of second openings; the light emitting units in the light emitting structure layer 220 are located in the second openings; and the light shielding layer 215 includes the pixel definition layer 212 .
[0063] Specifically, the pixel definition layer 212 is used to separate multiple light-emitting units. When the pixel definition layer 212 is a light-shielding layer 215, the pixel definition layer 212 can be made of black organic glue. The pixel definition layer 212 can be extended to part of the border area BA, or the pixel definition layer 212 can be extended from the display area AA to the border area BA and fully cover the border area BA. The pixel definition layer 212 is extended from the display area AA to the border area BA without adding a new film layer, and the process of manufacturing the display panel is not increased while improving the light leakage problem in the border area BA of the display panel.
[0064] Optional, continue to refer to Figure 6 The array substrate 210 further includes a support column layer 213 ; the support column layer 213 is located between the pixel definition layer 212 and the light emitting structure layer 220 ; the light shielding layer 215 includes the pixel definition layer 212 and the support column layer 213 .
[0065] Specifically, the support column layer 213 is used to support the mask used when the light-emitting unit is evaporated. When the pixel definition layer 212 and the support column layer 213 are both light-shielding layers 215, the pixel definition layer 212 and the support column layer 213 can be made of the same material. Extending the pixel definition layer 212 and the support column layer 213 from the display area AA to the frame area BA can further increase the OD value of the frame area BA, improve the light-shielding effect of the frame area BA, and further improve the light leakage problem of the display panel frame area BA.

The second insulating layer 242 is located on the light-emitting side of the light-emitting unit, and the second insulating layer 241 is extended from the display area AA to the frame area BA, which can further improve the light shielding effect of the frame area BA. When the light shielding layer 215 includes the second insulating layer 241, the second insulating layer 241 can be made of black organic glue.
[0070] Optional, Figure 7 is a schematic diagram of the structure of another display panel provided according to an embodiment of the present invention, referring to Figure 6 and Figure 7 The second conductive layer 243 includes a plurality of first electrode blocks 2431, a plurality of second electrode blocks 2433 and a plurality of first connecting parts 2432; two adjacent first electrode blocks 2431 along the first direction X are connected via the first connecting parts 2432; the first conductive layer 242 includes a plurality of second connecting parts 2421, and two adjacent second electrode blocks 2433 along the second direction Y are connected via the second connecting parts 2421.

One of the first electrode block 2431 and the second electrode block 2433 can be a touch sensing electrode, and the other can be a touch driving electrode.
[0072] Optional, continue to refer to Figure 6 and Figure 7 , the orthographic projection of the first connection portion 2432 on the array substrate 210 at least partially overlaps with the orthographic projection of the second connection portion 2421 on the array substrate 210. That is, the first connection portion 2432 and the second connection portion 2421 have an overlapping area.
[0073] Optional, continue to refer to Figure 6 The display panel further includes an encapsulation layer 230 ; the encapsulation layer 230 is located on a side of the light emitting structure layer 220 away from the array substrate 210 ; and the touch control layer 240 is located on a side of the encapsulation layer 230 away from the light emitting structure layer 220 .
[0074] Specifically, the encapsulation layer 230 may include at least two first inorganic layers and at least one first organic layer, the first inorganic layers and the first organic layers are alternately stacked, and the film layer closest to the light-emitting structure layer 220 and the film layer farthest from the light-emitting structure layer 220 in the encapsulation layer 230 are both first inorganic layers.

[0076] Specifically, the color of the color block 252 can be red, green or blue. In the display area AA, the color block 252 can correspond to the light-emitting unit one by one, and the color of the color block 252 is the same as the light-emitting color of the corresponding light-emitting unit. The color block 252 can absorb the light-emitting color of the light-emitting unit that does not correspond to it. The black matrix 251 has a light-shielding function. The orthographic projection of the black matrix 251 on the light-emitting structure layer 230 is set to be staggered with the light-emitting unit, so that the black matrix 251 can prevent the light emitted by two adjacent light-emitting units of different light-emitting colors from crosstalking with each other.

The material of the pixel definition layer 212, the material of the support column layer 213, the material of the second insulating layer 241 and the material of the color filter layer 250 can all be organic materials.

[0082] Specifically, after the bending region 120 is bent, a portion of the bending region 120 will be located on the light-emitting surface of the display panel, and the remaining bending region 120 will be located on the non-light-emitting surface of the display panel.
[0083] Extending the light shielding layer and the color filter layer from the display area AA to the bending area 120 can prevent light leakage from the bending area 120 remaining on the light-emitting surface after the bending area 120 is bent, further improving the light leakage problem in the frame area of the display panel.
[0084] Specifically, at least one of the light shielding layer and the color filter layer extending to the bending area 120 may be: at least one of the pixel definition layer, the support column layer, the second insulating layer and the color filter layer extending from the display area AA to the bending area 120 .
[0085] After the bending area 120 is bent, the binding area 130 is located on the backlight side of the display panel, which can avoid the problem of the binding area 130 being located on the light-emitting side of the display panel and causing a larger display panel frame. The backlight side of the display panel refers to the side away from the light-emitting side of the display panel.
[0086] Optional, continue to refer to Fig.10 The frame area includes a preset area 121 of the bending area 120 , and at least one of the light shielding layer and the color filter layer covers the preset area 121 .
[0087] Specifically, the preset area 121 may be the area left on the light-emitting surface of the display panel after the bending area 120 is bent. Providing at least one of the shading layer and the color filter layer to cover the preset area 121 can improve the light leakage problem in the border area of the display panel, and the shading layer and the color filter layer can also be used instead of the ink in the preset area 121 to improve the shading effect of the border area.
[0088] Optional, Fig.11 is a schematic diagram of the structure of another display panel provided according to an embodiment of the present invention, referring to Fig.11 The non-display area also includes a through-hole area 140; the through-hole area 140 includes a through-hole 141 and an edge area 142 surrounding the through-hole 141; the through-hole 141 is used to accommodate optical devices; and at least one of the shading layer and the color filter layer extends to the edge area 142.
[0089] Specifically, the optical device may be a camera. Specifically, at least one of the light shielding layer and the color filter layer extending to the edge area 142 may be: at least one of the pixel definition layer, the support column layer, the second insulating layer, and the color filter layer extending from the display area AA to the edge area 142. Providing at least one of the light shielding layer and the color filter layer extending to the edge area 142 can improve the problem of light leakage in the edge area 142, and can also replace ink with the light shielding layer and the color filter layer to improve the light shielding effect of the edge area 142.
[0090] Optionally, at least one of the shading layer and the color film layer covers the edge area. This arrangement can further improve the shading effect of the edge area.
[0091] Optionally, the light-shielding layer is a black film layer.
[0092] Specifically, compared with film layers of other colors, the black film layer has a better light-shielding effect. Setting the light-shielding layer to a black film layer can improve the light-shielding effect.
[0093] Optionally, the light-shielding layer is a black organic layer. Such a setting can improve the bending resistance of the light-shielding layer, so that after the light-shielding layer extends to the bending area, it will not cause the light-shielding layer to bend and break. Setting the light-shielding layer to a black organic layer facilitates the production of the display panel and can improve the production efficiency of the display panel.
[0094] Optional, Fig.12 is a schematic diagram of the structure of another display panel provided according to an embodiment of the present invention, referring to Fig.12 , the distance between the preset boundary BA1 of the light shielding layer 215 and the boundary of the display area AA is greater than or equal to the set distance; wherein the preset boundary BA1 is the boundary of the light shielding layer 215 away from the display area AA.
[0095] Specifically, a light shielding layer 215 may be provided in a part of the border area BA, and a region in the border area BA where the light shielding layer 215 is not provided may be coated with black ink. The set distance is greater than 0, and the set distance may be set according to actual needs. Exemplarily, the set distance may be the distance between the boundary of the display area AA and the boundary of the border area BA away from the display area AA, and in this way, the preset boundary BA1 of the light shielding layer 215 may coincide with the boundary of the border area BA away from the display area AA.
[0096] Optional, continue to refer to Fig.11 The preset boundary BA1 coincides with the boundary of the border area BA away from the display area AA. This arrangement allows the shading layer 215 to fully cover the border area BA, which not only improves the shading effect of the border area BA, but also eliminates the need to set black ink in the border area BA, thereby reducing the steps of setting black ink and improving the production efficiency of the display panel.
