[0002] Embodiments of the present disclosure relate to an array substrate and a display device. Background Art

[0003] With the continuous development of display technology, compared with traditional liquid crystal display (LCD) display technology, organic light-emitting diode (OLED) display technology has been widely used in smart electronic products such as smart phones and wearable smart devices because of its advantages such as self-luminescence, wide color gamut, high contrast, and light weight.

[0004] At present, smart electronic products with high screen-to-body ratio have gradually become the mainstream of the market due to their beautiful appearance and better user experience. With the continuous development of technology and market, smart electronic products with high screen-to-body ratio design can no longer meet people's needs, and smart electronic products with full-screen design have become the future development trend.

[0005] On the other hand, in order to realize the thin and light design of display devices (e.g., organic light emitting diode display devices), the display panel and the touch structure can be integrated together. Therefore, FMLOC (Flexible Multiple Layer On Cell) touch technology came into being. FMLOC touch technology is to directly make various electrode layers and various wirings of the touch structure on the packaging layer, so as to integrate the touch structure on the display panel. Therefore, the display device using FMLOC touch technology can not only realize the thin and light design of the display device, but also realize flexible display and flexible touch.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0040] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure should be understood by people with ordinary skills in the field to which the present disclosure belongs. "First", "second" and similar words used in the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0041] In order to further increase the screen-to-body ratio and realize a full-screen design, the camera assembly can be set below the screen. However, the inventor of the present application found that in a display device using FMLOC technology, since the metal grid line is set between two adjacent anodes, the metal grid line and the anode are both non-transparent structures, thereby forming a slit between the metal grid line and the two adjacent anodes; when visible light passes through the above slit, diffraction or interference is likely to occur, resulting in poor imaging quality of the camera assembly below.

[0042] For example, Figure 1 A schematic plan view of an array substrate is shown; Figure 1 As shown, the array substrate includes a base substrate 01, an anode layer 02 and a touch electrode layer 03; the anode layer 02 is arranged on the base substrate 01, and the touch electrode layer 03 is arranged on the side of the anode layer 02 away from the base substrate 01. An insulating layer or a passivation layer (not shown) is also arranged between the anode layer 02 and the touch electrode layer 03. The anode layer 02 includes a plurality of anodes 022; the touch electrode layer 03 includes a metal grid electrode 032, and the metal grid electrode 032 is formed by metal grid lines 034. Part of the metal grid lines 034 is arranged between two adjacent anodes 022, and the metal grid lines 034 and the anodes 022 are both non-transparent structures, so that a slit 09 is formed between the metal grid lines 034 and the two adjacent anodes 022; when visible light passes through the above-mentioned slit 09, diffraction or interference phenomenon is likely to occur, thereby causing the imaging quality of the camera assembly below the screen to deteriorate. In this regard, the inventor of the present application has thought of optimizing the design of the metal grid lines to avoid the above-mentioned slits, thereby ensuring the imaging quality of the camera assembly below the screen.

[0043] The disclosed embodiment provides an array substrate and a display device. The array substrate includes a base substrate, an anode layer, a packaging layer and a touch electrode layer; the base substrate includes a transparent display area; the anode layer is located on the base substrate and includes a plurality of anodes; the packaging layer is located on the side of the anode layer away from the base substrate; the touch electrode layer is located on the side of the packaging layer away from the anode layer and includes a conductive grid line, and within the transparent display area, the orthographic projection of the conductive grid line on the base substrate is connected to or partially overlapped with the orthographic projection of at least one of the plurality of anodes on the base substrate. In the array substrate, since the orthographic projection of the conductive grid line on the base substrate is connected to or partially overlapped with the orthographic projection of at least one of the plurality of anodes on the base substrate, the formation of a slit between the anode and the conductive grid line can be effectively avoided, thereby avoiding the diffraction or interference phenomenon of light when passing through the transparent display area. Therefore, when the array substrate is applied to a display device, the imaging quality of the camera assembly below the screen can be guaranteed.

[0044] The array substrate and the display device provided by the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0045] Figure 2 FIG. 1 is a plan view of an array substrate according to an embodiment of the present disclosure. Figure 2 As shown, the array substrate 100 includes a base substrate 110, an anode layer 120, and a packaging layer ( Figure 2 The substrate 110 includes a transparent display area 112; the anode layer 120 is located on the substrate 110 and includes a plurality of anodes 122; the encapsulation layer is located on the side of the anode layer 120 away from the substrate 110; the touch electrode layer 140 is located on the side of the encapsulation layer away from the anode layer 120 and includes a conductive grid line 142. Within the transparent display area 112, the orthographic projection of the conductive grid line 142 on the substrate 110 is connected to or partially overlapped with the orthographic projection of at least one of the plurality of anodes 122 on the substrate 110. It should be noted that the orthographic projection of the conductive grid line on the substrate 110 is connected to the orthographic projection of at least one of the plurality of anodes on the substrate, which means that there is no interval between the edges of the two orthographic projections, that is, the distance between the edges of the two orthographic projections is zero; the orthographic projection of the conductive grid line on the substrate is partially overlapped with the orthographic projection of at least one of the plurality of anodes on the substrate, which means that the two orthographic projections have an overlapping area.

[0046] In the array substrate provided in the embodiment of the present disclosure, since the orthographic projection of the conductive grid lines on the base substrate is connected to or partially overlaps with the orthographic projection of at least one of the multiple anodes on the base substrate, it is possible to effectively avoid the formation of slits between the anodes and the conductive grid lines, thereby avoiding diffraction or interference of light when passing through the transparent display area. Therefore, when the array substrate is applied to a display device, it can be ensured that the function of the optical functional component located in the transparent display area is not affected. For example, when the above-mentioned optical functional component is a camera component, the array substrate can ensure the imaging quality of the camera component; for another example, when the above-mentioned optical functional component is an optical fingerprint recognition component, the array substrate can ensure the fingerprint recognition accuracy of the optical fingerprint recognition component. It should be noted that although Figure 1 The array substrate shown adopts the GGRB pixel arrangement mode, but the array substrate provided by the embodiment of the present disclosure may also adopt other pixel arrangements, and the wire grid lines may also be arranged according to the specific pixel arrangement mode. Figure 2 As shown, within the transparent display area 112, the orthographic projection of the conductive grid line 142 on the base substrate 110 is connected to or partially overlapped with the orthographic projection of each of the plurality of anodes 122 on the base substrate 110. This arrangement can ensure that no gap is formed between the anode and the conductive grid line, and can also increase the distribution density of the conductive grid line, thereby reducing the touch blind area, increasing the touch accuracy, and reducing the overall resistance of the conductive grid line.

[0047] In some examples, such as Figure 2 As shown, within the transparent display area 112, the conductive grid lines 142 are arranged along the edge of the corresponding anode 122. In this way, the conductive grid lines can surround the edge of the anode, thereby further ensuring that no gap is formed between the anode and the conductive grid lines, and increasing the distribution density of the conductive grid lines.

[0048] It is worth noting that the planar shape of the anode is usually not a regular hexagon or pentagon, but includes a main body for driving the light-emitting layer to emit light and a connecting part for connecting to the driving circuit through a via hole (for example, Figure 2 In the array substrate provided by the embodiment of the present disclosure, the conductive grid lines are arranged along or around the main body of the anode, but do not include the connecting portion of the anode. Therefore, the orthographic projection of the conductive grid lines on the substrate substrate may be connected to or partially overlapped with the orthographic projection of a portion of the edge of at least one of the plurality of anodes on the substrate substrate, but not necessarily all the edges of the anode.

[0049] Figure 3 FIG. 1 is a schematic plan view of an array substrate provided according to an embodiment of the present disclosure. Figure 3As shown, the base substrate 110 also includes a non-transparent display area 114; Figure 2 and Figure 3 As shown, the plurality of anodes 122 include a plurality of anode groups 124, that is, the plurality of anodes 122 are divided into a plurality of anode groups 124; the density of the anode group 124 in the non-transparent display area 114 is greater than the density of the anode group 124 in the transparent display area 112; the transparent display area 112 includes an anode area 1124 and a transparent area 1126, the anode area 1124 is provided with at least one anode group 124, and the transparent area 1126 is not provided with an anode group 124. In this way, the array substrate has both a transparent display area 112 and a non-transparent display area 114, the transparent display area 112 can be displayed and optical functional components can be placed, and the non-transparent display area 114 can be displayed at high resolution. Therefore, when the array substrate is applied to a display device, the array substrate can realize a full-screen design and have a high-quality display screen. Of course, the embodiments of the present disclosure include but are not limited to this, and the base substrate may also include only a transparent display area, but not a non-transparent display area; at this time, optical functional components can be arranged under all display areas of the array substrate.

[0050] It should be noted that in order to simply show the difference between the transparent display area and the non-transparent display area, Figure 3 Each small rectangle in the figure represents an anode group; in addition, each of the above-mentioned anodes can be used to drive the light-emitting layer to emit light of a single color, corresponding to the sub-pixels in the display device; the above-mentioned anode group may include multiple anodes, which respectively drive different light-emitting layers to emit light of different colors, corresponding to the pixels in the display device.

[0051] In some examples, such as Figure 2 and Figure 3 As shown, each anode group 124 includes a first anode 1221, two second anodes 1222 and a third anode 1223; within the transparent display area 112, the orthographic projection of the conductive grid line 142 on the base substrate 110 is connected to or partially overlapped with the orthographic projection of the first anode 1221, the second anode 1222 and the third anode 1223 in the anode group 124 on the base substrate 110. Such a configuration can ensure that no slits are formed between the first anode, the second anode and the third anode and the conductive grid line, and can also increase the distribution density of the conductive grid line, thereby reducing the touch blind area, increasing the touch accuracy, and reducing the overall resistance of the conductive grid line.

[0052] For example, the first anode may be the anode of the first color sub-pixel, the second anode may be the anode of the second color sub-pixel, and the third anode may be the anode of the third color sub-pixel. For example, the first color sub-pixel may be a red sub-pixel, the second color sub-pixel may be a green sub-pixel, and the third color sub-pixel may be a blue sub-pixel. Of course, the embodiments of the present disclosure include but are not limited to this, and the above three color sub-pixels may also be sub-pixels of other colors.

[0053] In some examples, such as Figure 2 As shown, within the transparent display area 112, the conductive grid lines 142 include a first conductive line 1421 located in the anode area 1124 and a second conductive line 1422 located in the transparent area 1126, and the first conductive line 1421 is formed into a first grid connected to or partially overlapped with each anode 122 in the anode group 124. In this arrangement, since no anode is provided in the transparent area, the second conductive line will not form a slit with the anode; and the first conductive line is formed into a first grid connected to or partially overlapped with each anode in the anode group, thereby effectively avoiding the formation of a slit between the anode and the first conductive line, thereby avoiding the diffraction or interference phenomenon of light when passing through the anode area.

[0054] In some examples, such as Figure 2 As shown, the second wire 1422 is formed as a non-grid line, such as a straight line, connecting two adjacent first wires 1421. Since no anode is provided in the transparent area, the aperture ratio of the transparent area can be increased by arranging the second wire as a straight line, thereby increasing the amount of light passing through the transparent area, thereby improving the performance and accuracy of the optical functional component provided in the transparent display area. In addition, the risk of diffraction at the chamfer of the anode can be reduced by arranging the second wire as a straight line.

[0055] In some examples, within the non-transparent display area, the conductive grid lines are connected to or partially overlapped with at least one of the plurality of anodes. That is, in the non-transparent display area, the conductive grid lines may be arranged in the same manner as the conductive grid lines in the transparent display area; for example, the specific shape and position of the conductive grid lines within the non-transparent display area may be referred to. Figure 2 Of course, the embodiments of the present disclosure include but are not limited to this, and the conductive grid lines in the non-transparent display area may also be located between two adjacent anodes and spaced apart from the two adjacent anodes.

[0056] In some examples, the touch electrode layer 140 includes a plurality of metal grid electrodes, the conductive grid lines 142 include metal grid lines, and the metal grid lines 142 form the above-mentioned metal grid electrodes. In other words, the above-mentioned touch electrode layer is formed by a metal grid.

[0057] Figure 4 FIG. 1 is a plan view of another array substrate provided according to an embodiment of the present disclosure. Figure 4As shown, within the non-transparent display area 114, the conductive grid line 142 is located between two adjacent anodes 122 and is spaced apart from the two adjacent anodes 122. Since the non-transparent display area does not need to be light-transmissive, the slits formed between the conductive grid line and the two adjacent anodes will not cause the above-mentioned problems caused by diffraction or interference.

[0058] Figure 5 According to an embodiment of the present disclosure, an array substrate is provided along Figure 2 Schematic diagram of the cross section along the AA direction. Figure 5 As shown, the array substrate 100 includes the above-mentioned base substrate 110, anode layer 120, encapsulation layer 130 and touch electrode layer 140; in addition, the array substrate 100 also includes a pixel defining layer 150. The pixel defining layer 150 is located on the side of the anode layer 120 away from the base substrate 110, and the pixel defining layer 150 includes a plurality of openings 152, and the plurality of openings 152 are arranged one-to-one corresponding to the plurality of anodes 122. Within the transparent display area 112, the orthographic projection of the conductive grid line 142 on the base substrate 110 falls within the orthographic projection of the pixel defining layer 150 on the base substrate 110, and is spaced from the orthographic projection of the edge of the opening 152 on the base substrate 110. In other words, the conductive grid line has a certain distance from the edge of the opening, thereby preventing the conductive grid line from affecting the light-emitting angle, thereby ensuring a certain opening viewing angle. In some examples, such as Figure 5 As shown, within the transparent display area 112, the orthographic projection of the conductive grid line 142 on the base substrate 110 and the orthographic projection of at least one of the plurality of anodes 122 on the base substrate 110 have an overlapping area, and the width d of the overlapping area ranges from 0 to 3.5 microns. In this way, under certain process error conditions, it is ensured that no slit is formed between the anode and the conductive grid line, thereby further effectively avoiding diffraction or interference of light when passing through the transparent display area.

[0059] In some examples, the line width of the conductive grid lines ranges from 2-5 microns, and the size of the anodes ranges from 10-80 microns.

[0060] In some examples, such as Figure 5 As shown, the array substrate 100 further includes a pixel driving layer 160, a planar layer 170, a light emitting layer 180 and a cathode layer 190. The pixel driving layer 160 is located between the base substrate 110 and the anode layer 120, the planar layer 170 is located between the pixel driving layer 160 and the anode layer 120, the light emitting layer 180 is located on the side of the anode layer 120 away from the planar layer 170, and the cathode layer 190 is located between the light emitting layer 180 and the encapsulation layer 130. It should be noted that the array substrate may also include other layer structures for realizing the display function, such as a hole injection layer, a hole transport layer, an electron injection layer, and an electron transport layer, etc.; the embodiments of the present disclosure are not limited here.

[0061] In some examples, such as Figure 5 As shown, the array substrate 100 further includes an optical functional component 200 configured to receive or emit light, and the optical functional component 200 is located on a side of the base substrate 110 away from the anode layer 120, and is located within the transparent display area 112. In this way, light can enter the optical functional component through the transparent display area of ​​the base substrate, or light emitted by the optical functional component can be emitted through the transparent display area of ​​the base substrate. Thus, the array substrate can realize the corresponding function of the optical functional component while displaying.

[0062] For example, the optical functional component 200 includes at least one of a camera component, a face recognition component, and an optical fingerprint recognition component, so as to realize at least one of a camera function and a fingerprint recognition function. It should be noted that the above-mentioned face recognition component may include an ambient light sensor, a distance sensor, an infrared lens, a flood camera, and a dot matrix projector. Of course, the embodiments of the present disclosure include but are not limited to this, and the above-mentioned face recognition component may also include other functional components.

[0063] For example, the above-mentioned substrate may be a transparent substrate, such as a glass substrate, a quartz substrate, a plastic substrate, etc. In addition, the above-mentioned substrate may also be a flexible transparent substrate, such as a polyimide (PI) substrate. The embodiments of the present disclosure include but are not limited to this.

[0064] For example, the anode layer may be made of metal material, and the touch electrode layer may also be made of metal material.

[0065] For example, the encapsulation layer may include a stacked structure of an organic encapsulation layer and an inorganic encapsulation layer; the material of the inorganic encapsulation layer may be selected from one or more of silicon oxide, silicon nitride or silicon oxynitride; the material of the organic encapsulation layer may be organic resin, polyimide, polyacrylate, etc. Of course, the embodiments of the present disclosure include but are not limited to this.

[0066] For example, the above-mentioned pixel driving layer may include a pixel driving circuit, and the pixel driving circuit provided in the embodiment of the present disclosure may refer to the general design; for example, the pixel driving circuit may also include thin film transistors, capacitors and other structures, which will not be repeated in the embodiment of the present disclosure.
