[0001] This application relates to the field of display technology, and more particularly to a display device and electronic device. Background Technology

[0002] With the development of technology, display devices have been widely used in people's lives. For example, liquid crystal displays and electronic paper displays are used in various electronic devices.

[0003] In related technologies, the manufacturing process of a display device includes: first, providing a first motherboard and a second motherboard, forming a barrier on the first or second motherboard to divide the display area of ​​the display device into multiple pixel units; then, applying a display material (electron paste or liquid crystal material) to the display area of ​​the first or second motherboard and applying a border adhesive to the non-display area of ​​the first or second motherboard; finally, bonding the first and second motherboards together and cutting them along the cutting lines on the first and second motherboards to obtain multiple display devices. However, during the bonding process of the first and second motherboards, residual gas may remain in the pixel units, and the distribution of electron paste or liquid crystal material in each pixel unit may be uneven, resulting in poor display performance of the display device. Utility Model Content

[0004] This application proposes a display device and electronic device to solve the technical problem that residual gas may exist in the pixel unit and the electronic paste or liquid crystal material in each pixel unit is unevenly distributed, resulting in poor display effect of the display device.

[0005] On one hand, this application provides a display device having a display area and a non-display area surrounding the display area. The display device includes: a first substrate; a second substrate disposed at a distance from the first substrate; and a barrier wall located within the display area and disposed between the first substrate and the second substrate to divide the display area into a plurality of pixel units. The barrier wall includes a first body and a second body connected to the first body. The first body and / or the second body forms a through hole. Before the first substrate and the second substrate are mated together, the through hole is used to connect two adjacent pixel units. During the mating process of the first substrate and the second substrate, the opening of the through hole gradually decreases until it closes.

[0006] Optionally, the first body includes a flexible portion having the through hole formed therein, and / or the second body has the through hole formed at one end facing the flexible portion.

[0007] Optionally, one of the first body and the second body is disposed on the side of the first substrate facing the second substrate, and the other of the first body and the second body is disposed on the side of the second substrate facing the first substrate, and the flexible part is disposed in abutment against the second body.

[0008] Alternatively, the second main body is disposed on the side of the first substrate facing the second substrate, the first main body is disposed on the side of the second main body away from the first substrate, and the flexible part abuts against the second substrate;

[0009] Alternatively, the second main body is disposed on the side of the second substrate facing the first substrate, the first main body is disposed on the side of the second main body away from the second substrate, and the flexible portion abuts against the first substrate.

[0010] Optionally, the first body has a receiving groove adapted to the second body, and the second body is received in the receiving groove on the side facing the first body; the first body has the through hole, the through hole penetrates the receiving groove, and / or the second body has the through hole on the side facing the first body.

[0011] Optionally, the receiving groove has a first inclined guide surface on the side facing the second body, and / or the second body has a second inclined guide surface on the side facing the first body.

[0012] Optionally, the cross-sectional area of ​​the receiving groove gradually decreases in the direction in which the second body is inserted into the receiving groove.

[0013] Optionally, the display device further includes a barrier wall located in the non-display area. The barrier wall is disposed between the first substrate and the second substrate and surrounds the barrier wall at intervals, so that a receiving cavity is formed between the barrier wall and the barrier wall. Before the first substrate and the second substrate are attached together, the through hole is also used to connect the adjacent pixel unit with the receiving cavity.

[0014] Optionally, the barrier wall includes a main body and a sealing part, one of the main body and the sealing part is disposed on the side of the first substrate facing the second substrate, and the other of the main body and the sealing part is disposed on the side of the second substrate facing the first substrate, and the main body and the sealing part are disposed in abutment against each other.

[0015] Alternatively, the main body is disposed on the side of the first substrate facing the second substrate, and the sealing part is disposed on the side of the main body away from the first substrate, and the sealing part abuts against the second substrate;

[0017] Optionally, the display device further includes a bezel adhesive located in and surrounding the non-display area, the bezel adhesive being disposed between the first substrate and the second substrate.

[0018] On the other hand, this application also provides an electronic device, including the display device described above.

[0019] As can be seen from the above technical solution, the display device provided in this application divides the baffle wall into a first main body and a second main body, and through holes are formed on the first main body and / or the second main body. Before the first substrate and the second substrate are bonded together, the through holes are used to connect two adjacent pixel units. During the bonding process of the first substrate and the second substrate, the opening of the through holes gradually decreases, allowing gas in the pixel unit to be discharged in time and allowing the display material to flow in the two adjacent pixel units, so that the display material is evenly distributed in each pixel unit, thereby improving the display effect of the display device. Moreover, after the first substrate and the second substrate are bonded together, the closing of the opening of the through holes can prevent the display material from flowing in the two adjacent pixel units, thereby improving the reflectivity and contrast of the display device.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0030] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0031] This application provides a display device 10, which has a display area and a non-display area surrounding the display area. The display area is filled with a display material, which can be an electronic paste or a liquid crystal material. When the display area is filled with an electronic paste, the display device 10 is an electronic paper display device; when the display area is filled with a liquid crystal material, the display device 10 is a liquid crystal display device.

[0032] like Figures 1 to 7As shown, the display device 10 includes a first substrate 100, a second substrate 200, and a barrier 300. The first substrate 100 and the second substrate 200 are disposed at a distance from each other. The barrier 300 is located in the display area and disposed between the first substrate 100 and the second substrate 200 to divide the display area into pairs of pixel units. The barrier 300 includes a first body 310 and a second body 320 connected to the first body. The first body 310 and / or the second body 320 are formed with through holes 330. Before the first substrate 100 and the second substrate 200 are attached, the through holes 330 are used to connect two adjacent pixel units. During the attachment process of the first substrate 100 and the second substrate 200, the opening of the through holes 330 gradually decreases until it closes. Compared with related technologies, the display device 10 provided in this application divides the barrier 300 into a first main body 310 and a second main body 320, and through holes 330 are formed on the first main body 310 and / or the second main body 320. Before the first substrate 100 and the second substrate 200 are bonded together, the through holes 330 are used to connect two adjacent pixel units. During the bonding process of the first substrate 100 and the second substrate 200, the opening of the through holes 330 gradually decreases, allowing gas in the pixel unit to be discharged in time and allowing the display material to flow in the two adjacent pixel units, so that the display material is evenly distributed in each pixel unit, thereby improving the display effect of the display device 10. Moreover, after the first substrate 100 and the second substrate 200 are bonded together, the closing of the opening of the through holes 330 can prevent the display material from flowing in the two adjacent pixel units, thereby improving the reflectivity and contrast of the display device 10.

[0033] One of the first substrate 100 and the second substrate 200 is a driving substrate, and the other of the first substrate 100 and the second substrate 200 is a conductive substrate. Both the first substrate 100 and the second substrate 200 have a display area and a non-display area surrounding the display area. The display area on the first substrate 100 and the display area on the second substrate 200 are disposed opposite to each other, and the non-display area on the first substrate 100 and the non-display area on the second substrate 200 are disposed opposite to each other.

[0034] The following example uses the first substrate 100 as a conductive substrate. Figure 1 As shown, the first substrate 100 includes a first substrate 110 and a first electrode layer 120, with the first electrode layer 120 stacked on the side of the first substrate 110 facing the second substrate.

[0035] The first substrate 110 is made of a light-transmitting rigid material, such as glass or acrylic, giving it a certain degree of hardness and flatness. It should be noted that in other embodiments, the first substrate 110 can also be made of a light-transmitting flexible material, such as PET (polyethylene terephthalate), PEN (polyethylene naphthalate), or PI (polyimide), giving it a certain degree of flexibility to improve comfort and enhance user experience.

[0036] The first electrode layer 120 is made of a light-transmitting conductive material, such as an ITO electrode layer.

[0037] Optional, such as Figure 7 As shown, the first substrate 100 also includes a color layer 130, which can be an RGB film. The color layer 130 is disposed between the first substrate 110 and the first electrode layer 120. The color layer 130 enables the display device to achieve a color display effect, thereby improving the user experience. It should be noted that in other embodiments, the first substrate 100 may not have the color layer 130; simply adding colored conductive particles to the liquid crystal material or electronic paste can also enable the display device to achieve a color display effect. Of course, if the display device only requires a black and white display effect, it is not necessary to provide the color layer 130 on the first substrate 100.

[0038] Furthermore, the first substrate 100 also includes a planarization layer 140, which is disposed between the first electrode layer 120 and the color layer 130. The planarization layer 140 is made of an organic insulating material. For example, the planarization layer 140 is mainly formed by patterning polymers and small molecule organic compounds (e.g., exposure using a mask followed by development and etching) and then curing. The planarization layer 140 is used to planarize the color layer 130, thereby allowing the first electrode layer 120 to be better stacked on the planarization layer 140, thus improving product yield. The planarization layer 140 can also increase the thickness of the first substrate 100, thereby improving the first substrate 100's resistance to pressure damage. It should be noted that in other embodiments, the color layer 130 can also be disposed on the side of the first electrode layer 120 facing away from the first substrate 110, thus eliminating the need for the planarization layer 140 and reducing production costs.

[0039] Furthermore, the first substrate 100 also includes a black matrix 150, which is disposed between the first electrode layer 120 and the first substrate 110 and surrounds the planarization layer 140. The black matrix 150 is used to block light, improve contrast and prevent light leakage, thereby enabling the display device 10 to have a better display effect.

[0040] Furthermore, the first substrate 100 also includes an organic layer 160, which is stacked on the side of the first electrode layer 120 facing away from the first substrate 110. The organic layer 160 is made of an organic insulating material, such as a polymer and small molecule organic compound patterned (e.g., exposed using a mask followed by development and etching) and then cured. The organic layer 160 is used to planarize the side of the first electrode layer 120 facing away from the first substrate 110, so that the second substrate 200 can better adhere to the first substrate 100, thereby improving product yield. Moreover, the organic layer 160 can also increase the thickness of the first substrate 100, thereby improving the first substrate 100's resistance to pressure damage.

[0041] Optional, such as Figure 1 As shown, the second substrate 200 is a driving substrate. The second substrate 200 includes a second substrate 210 and a second electrode layer 220. The second electrode layer 220 is stacked on the side of the second substrate 210 facing the first substrate 100.

[0042] The second substrate 210 is made of a rigid material, such as glass or acrylic, giving it a certain degree of rigidity and flatness. It should be noted that in other embodiments, the second substrate 210 can also be made of a flexible material, such as PET (polyethylene terephthalate), PEN (polyethylene naphthalate), or PI (polyimide), giving it a certain degree of flexibility to improve comfort and enhance user experience.

[0043] The second electrode layer 220 is made of a light-transmitting conductive material, such as an ITO electrode layer.

[0044] Furthermore, such as Figure 1 As shown, the second substrate 200 further includes an insulating layer 230, which is stacked on the side of the second electrode layer 220 facing away from the second substrate 210. The insulating layer 230 can be made of materials such as PET, PP, PC, and PVC, thereby giving the insulating layer 230 good insulation performance and temperature resistance. It should be noted that in other embodiments, such as... Figure 2 As shown, the insulating layer 230 can also be disposed between the second substrate 210 and the second electrode layer 220.

[0045] Optionally, the second substrate 200 further includes a thin-film transistor 240 disposed on the second substrate 210, for example, between the second substrate 210 and the insulating layer 230. The thin-film transistor 240 is used to control the brightness and color of the pixels to ensure the normal operation and high performance of the display device 10. It is understood that there can be multiple thin-film transistors 240, so that one thin-film transistor 240 is disposed at the corresponding position of each pixel unit.

[0046] Furthermore, such as Figure 2 As shown, Figure 2 The sectional view direction is perpendicular to Figure 1 In the cross-sectional view, the second substrate 200 also has a soldering area (PAD area), that is, one side of the second substrate 210 has an extension 260 extending outward away from the display area. The second electrode layer 220 and the thin film transistor 240 are both provided with soldering portions on the extension 260, and the insulating layer 230 may also be partially provided on the extension 260.

[0047] It should be noted that, in other embodiments, the second substrate 200 may also include the planarization layer and organic layer described above, in order to perform planarization treatment on the second substrate 200.

[0048] Optional, such as Figure 1As shown, the first body 310 and the second body are in a mesh-like shape, and the first body 310 includes a flexible portion 311. For example, the first body 310 as a whole is a flexible component or adhesive material. The flexible portion 311 has through holes 330. Before the first substrate 100 and the second substrate 200 are attached, the through holes 330 are used to connect two adjacent pixel units. During the attachment process of the first substrate 100 and the second substrate 200, the flexible portion 311 is deformed due to the pressure of the second body 320, thereby causing the opening of the through holes 330 to gradually decrease until it closes. In this embodiment, the first body 310 is disposed on the side of the first electrode layer 120 facing the second substrate 200, and the second body 320 is disposed on the side of the insulating layer 230 facing the first substrate 100. The flexible portion 311 is disposed in abutment against the second body 320. This ensures the sealing performance between the first body 310 and the second body 320, preventing display material from flowing through the gap between the first body 310 and the second body 320 into adjacent pixel units, thereby improving the reflectivity and contrast of the display device 10. It should be noted that in other embodiments, the first body 310 may also be disposed on the side of the insulating layer 230 facing the first substrate 100, and the second body 320 may be disposed on the side of the first electrode layer 120 facing the second substrate 200, with the flexible portion 311 abutting against the second body 320. Alternatively, the second body 320 is disposed on the side of the first electrode layer 120 facing the second substrate 200, and the first body 310 is disposed on the side of the second body 320 away from the first electrode layer 120, with the flexible portion 311 abutting against the second electrode layer 220 or the insulating layer 230. Alternatively, the second body 320 is disposed on the side of the second electrode layer 220 or the insulating layer 230 facing the first substrate 100, and the first body 310 is disposed on the side of the second body 320 away from the second electrode layer 220 or the insulating layer 230, with the flexible portion 311 abutting against the first electrode layer 120 or the organic layer 160.

[0049] Furthermore, the through-hole 330 is also used to connect adjacent pixel units and non-display areas. During the bonding process of the first substrate 100 and the second substrate 200, the through-hole 330 can discharge residual air and excess display material from the display area. After the bonding process of the first substrate 100 and the second substrate 200, the opening of the through-hole 330 is closed, thereby preventing the display material in the pixel unit adjacent to the non-display area from flowing into the non-display area.

[0050] Optional, such as Figure 2As shown, the first body 310 includes a flexible portion 311, and the second body 320 has a through hole 330 formed at one end facing the flexible portion 311. Before the first substrate 100 and the second substrate 200 are bonded together, the through hole 330 is used to connect two adjacent pixel units. During the bonding process of the first substrate 100 and the second substrate 200, the flexible portion 311 deforms due to the pressure of the second body 320, thereby causing the flexible portion 311 to gradually fill the through hole 330, that is, the opening of the through hole 330 gradually decreases until it closes. It can be understood that in this embodiment, the arrangement of the first body 310 and the second body 320 can be the same as the arrangement of the first body 310 and the second body 320 described above, and will not be repeated here.

[0051] It should be noted that in other embodiments, both the flexible part 311 and the second body 320 may be provided with through holes 330, but the through holes 330 on the flexible part 311 and the through holes 330 on the second body 320 are misaligned.

[0052] Optional, such as Figure 3 and Figure 4 As shown, both the first body 310 and the second body 320 are made of a light-transmitting rigid material. The first body 310 is disposed on the side of the first electrode layer 120 facing the second substrate 200, and the second body 320 is disposed on the side of the insulating layer 230 facing the first substrate 100, with the second body 320 and the first body 310 abutting against each other. The first body 310 has a receiving groove 312 adapted to the second body 320, and the side of the second body 320 facing the first body 310 is received in the receiving groove 312. The first body 310 has a through hole 330 that penetrates the receiving groove 312. During the process of moving the first substrate 100 and the second substrate 200, the side of the second body 320 facing the first body 310 is gradually inserted into the receiving groove 312, thereby gradually reducing the opening of the through hole 330 until it closes. It is understandable that, since the side of the second body 320 facing the first body 310 is adapted to the receiving groove 312, after the first substrate 100 and the second substrate 200 are attached, the side of the second body 320 facing the first body 310 is received in the receiving groove 312, which can increase the flow path of the display material in the two adjacent pixel units, that is, increase the difficulty of the flow of the display material in the two adjacent pixel units, thereby preventing the flow of the display material in the two adjacent pixel units, so as to improve the reflectivity and contrast of the display device 10.

[0053] It should be noted that in other embodiments, the first body 310 may also be disposed on the side of the insulating layer 230 facing the first substrate 100, and the second body 320 may be disposed on the side of the first electrode layer 120 facing the second substrate 200, and the second body 320 and the first body 310 may be disposed in contact with each other.

[0054] It should be noted that in other embodiments, a through hole 330 may also be formed on the side of the second body 320 facing the first body 310, and the through hole 330 on the first body 310 and the through hole 330 on the second body 320 are misaligned.

[0055] Furthermore, such as Figure 4 As shown, the receiving groove 312 has a first inclined guide surface 3121 on the side facing the second body 320. That is, in the direction in which the second body 320 is inserted into the receiving groove 312, the cross-sectional area of ​​the receiving groove 312 on the side facing the second body 320 gradually decreases. The first inclined guide surface 3121 can provide a guiding effect for the insertion of the second body 320, so that when the first substrate 100 and the second substrate 200 are attached, the second body 320 is more easily inserted into the receiving groove 312.

[0056] Furthermore, a second inclined guide surface 321 is formed on the side of the second body 320 facing the first body 310. That is, in the direction in which the second body 320 is inserted into the receiving groove 312, the cross-sectional area of ​​the second body 320 on the side facing the first body 310 gradually decreases. The second inclined guide surface 321 can provide a guiding effect for the insertion of the second body 320, thereby making it easier for the second body 320 to be inserted into the receiving groove 312 when the first substrate 100 and the second substrate 200 are mated. It is understood that in the same embodiment, only the first inclined guide surface 3121 or the second inclined guide surface 321 may be provided, or both the first inclined guide surface 3121 and the second inclined guide surface 321 may be provided simultaneously.

[0057] Optional, such as Figure 5 As shown, the first body 310 has a receiving groove 312 adapted to the second body 320, and the side of the second body 320 facing the first body 310 is received in the receiving groove 312. A through hole 330 is formed on the side of the second body 320 facing the first body 310. During the process of the first substrate 100 and the second substrate 200, the side of the second body 320 facing the first body 310 is gradually inserted into the receiving groove 312, thereby causing the opening of the through hole 330 to gradually decrease until it is closed.

[0058] Furthermore, such as Figure 6 As shown, in the direction in which the second body 320 is inserted into the receiving groove 312, the cross-sectional area of ​​the receiving groove 312 gradually decreases. Since the second body 320 is adapted to the receiving groove 312, in the direction in which the second body 320 is inserted into the receiving groove 312, the cross-sectional area of ​​the side of the second body 320 facing the first body 310 also gradually decreases, thereby making it easier for the second body 320 to be inserted into the receiving groove 312 when the first substrate 100 and the second substrate 200 are attached.

[0059] Optional, such as Figure 1 As shown, the display device 10 also includes a barrier wall 400 located in the non-display area. The barrier wall 400 is disposed between the first electrode layer 120 and the insulating layer 230 and surrounds the barrier wall 300 at intervals, so that a receiving cavity 600 is formed between the barrier wall 400 and the barrier wall 300. Before the first substrate 100 and the second substrate 200 are bonded together, the through hole 330 is also used to connect the adjacent pixel unit and the receiving cavity 600. The receiving cavity 600 is used to receive residual gas and excess display material discharged from the display area, thereby preventing excess display material from continuing to overflow. In this embodiment, the barrier wall 400 can be disposed on the first electrode layer 120 and abut against the insulating layer 230, or the barrier wall 400 can be disposed on the insulating layer 230 and abut against the first electrode layer 120. It should be noted that in other embodiments, the barrier wall 400 may also be disposed on the first substrate 110 and abut against the second substrate 210; or, the barrier wall 400 may also be disposed on the second substrate 210 and abut against the first substrate 110. The arrangement of the barrier wall 400 can be designed according to the actual situation.

[0060] Furthermore, the barrier wall 400 includes a main body 410 and a sealing part 420. The main body 410 is disposed on the side of the insulating layer 230 facing the first substrate 100, and the sealing part 420 is disposed on the side of the first electrode layer 120 facing the second substrate 200. The main body 410 and the sealing part 420 are disposed in abutment against each other. The abutment between the main body 410 and the sealing part 420 can enhance the sealing effect on the receiving cavity 600. It should be noted that in other embodiments, the sealing part 420 may also be disposed on the main body 410. For example, the main body 410 may be disposed on the side of the first electrode layer 120 facing the second substrate 200, and the sealing part 420 may be disposed on the side of the main body 410 away from the first electrode layer 120 and abut against the insulating layer 230. Alternatively, the main body 410 may be disposed on the side of the insulating layer 230 facing the first substrate 100, and the sealing part 420 may be disposed on the side of the main body 410 away from the insulating layer 230 and abut against the first electrode layer 120. This can also enhance the sealing effect on the receiving cavity 600.

[0061] Optional, such as Figure 1 As shown, the display device 10 also includes a bezel adhesive 500, which is located in the non-display area and surrounds the barrier wall 400. The bezel adhesive 500 is disposed between the first substrate 110 and the second substrate 210, and is used to bond the first substrate 110 to the second substrate 210. It should be noted that in other embodiments, the bezel adhesive 500 is disposed between the first electrode layer 120 and the insulating layer 230, or between the organic layer 160 and the second electrode layer 220.

[0062] Among them, the frame adhesive 500 is mainly made of environmentally friendly solvent-free polyurethane or epoxy resin and other materials, which makes the frame adhesive 500 have the characteristics of strong adhesion, rapid curing, high temperature resistance, cold resistance and good weather resistance.

[0063] The working principle of the display device 10 is as follows: by changing the electric field of the first electrode layer 120 and the second electrode layer 220, the electron paste or liquid crystal material in each pixel unit is subjected to the electric field and migrates and aligns, thereby displaying a preset pattern.
