Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display module and a display terminal. Background Art

[0002] After the touch display module is manufactured, its touch functionality needs to be tested. This is typically done by rubbing a copper rod along the display surface of the module to simulate the user's interaction with the display using a finger or stylus. After the copper rod rubs the display surface, bright spots will appear in localized areas of the display module (such as corners), which manifest as localized brightening.

[0003] Therefore, it is urgent to improve the aforementioned technical issues. Summary of the Invention

[0004] This application provides a display module and a display terminal, which improves the technical problem that bright spots easily appear in local areas of the display module after the copper rod friction test process.

[0005] To achieve the above objectives, according to a first aspect of this application, a display module is provided, comprising:

[0006] The display panel includes a main body and an extension on one side of the main body. The main body has a connecting area and corner areas on both sides of the connecting area on the side near the extension. The main body in the connecting area is connected to the extension. The side wall of the main body in the corner area facing the extension is a first side wall.

[0007] A first functional layer is disposed on the side of the main body opposite to the light-emitting surface of the display module. The first functional layer is bonded to the display panel by a first adhesive layer, and the sidewall of the first functional layer facing the extension corresponding to the corner area is a second sidewall; and

[0008] The first insulating portion covers at least the sidewall of the first adhesive layer between the first sidewall and the second sidewall.

[0009] Optionally, the display module further includes:

[0010] A second insulating portion is disposed on the side of the display panel away from the first functional layer, and the second insulating portion at least covers the end of the extension portion near the main body portion;

[0011] Wherein, the impedance of the first insulating part is greater than or equal to the impedance of the second insulating part.

[0012] Optionally, the display module further includes:

[0013] The second functional layer is disposed on the side of the display panel away from the first functional layer. The orthographic projection of the second functional layer on the main body is located inside the main body. The side wall of the second functional layer facing the extension corresponding to the corner area is the third side wall. The third side wall is spaced apart from the first side wall.

[0014] The second insulating portion extends to the connection area and covers at least a portion of the main body of the connection area, the second insulating portion covers at least a portion of the main body of the corner area, and the first insulating portion covers the first sidewall and is disposed in contact with the second insulating portion.

[0015] Optionally, the first insulating part and the second insulating part are made of the same material.

[0016] Optionally, the display module further includes a cover plate disposed on the side of the second functional layer opposite to the display panel, the edge of the cover plate extending beyond the edge of the display panel, and the first insulating portion abutting against the surface of the cover plate near the display panel.

[0017] Optionally, the first insulating portion is continuously disposed along the periphery of the display panel and covers the sidewall of the first adhesive layer between the sidewall of the first functional layer and the sidewall of the display panel.

[0018] Optionally, the first functional layer includes a back panel layer, which is bonded to the display panel via the first adhesive layer. The material of the back panel layer is an insulating material. The sidewall of the back panel layer in the corner area is flush with the first sidewall, and the first insulating portion at least covers part of the sidewall of the back panel layer.

[0019] Optionally, the first functional layer further includes a conductive layer disposed on the side of the backplate layer away from the main body, and the impedance of the conductive layer is less than the impedance of the backplate layer.

[0020] Optionally, the display module includes a light-transmitting hole that penetrates the display panel and the first functional layer. The sidewall of the light-transmitting hole is provided with the third insulating portion. The third insulating portion at least covers the sidewall of the first adhesive layer between the display panel and the first functional layer within the light-transmitting hole. The third insulating portion and the first insulating portion are made of the same material.

[0021] According to a second aspect of this application, a display terminal is provided, including the display module described above.

[0022] In the display module of this application embodiment, by providing a first insulating part at least between the first sidewall of the main body portion in the corner area and the second sidewall of the first functional layer corresponding to the corner area, the static electricity generated by the friction of the copper rod is blocked by the first insulating part when it is conducted from the light-emitting surface of the main body portion to the sidewall of the main body portion. The static electricity cannot enter the space between the main body portion and the first functional layer from the corner area, thereby preventing the appearance of bright spots in the main body portion of the corner area due to charge accumulation.

[0046] 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 a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] According to a first aspect of this application, a display module 2 is provided, such as... Figures 3 to 5 As shown, the display module 2 includes a display panel 21, a first functional layer 22, and a first insulating portion 24. The display panel 21 includes a main body 211 and an extension 212 disposed on one side of the main body 211. The main body 211 has a connecting area and corner areas B1 disposed on both sides of the connecting area on the side near the extension 212. The main body 211 in the connecting area is connected to the extension 212. The sidewall of the main body 211 facing the extension 212 in the corner area B1 is a first sidewall 211a. The first functional layer 22 is disposed on the side of the main body 211 away from the light-emitting surface of the display module 2. The first functional layer 22 is bonded to the display panel 21 by a first adhesive layer. The sidewall of the first functional layer 22 facing the extension 212 corresponding to the corner area B1 is a second sidewall 22a. The first insulating portion 24 at least covers the sidewall of the first adhesive layer between the first sidewall 211a and the second sidewall 22a.

[0048] In some embodiments, the display panel 21 may be an OLED panel, a Mini-LED panel, a Micro-LED panel, etc.

[0049] like Figure 3 As shown, the display panel 21 includes a main body 211 and an extension 212. The main body 211 has a display area with multiple sub-pixels, which can be used to display images. The sub-pixels may include red, green, and blue sub-pixels, thereby enabling color display. The light-emitting surface of the display module 2 is the viewing side of the display panel 21.

[0050] The extension 212 may be provided with a bonding area, which can be bonded to a bonding component. The bonding component may be a driver chip, a flip-chip film, a flexible circuit board, a printed circuit board, etc., but is not limited to these. The bonding component can be used to input driving signals to the sub-pixels of the display area, thereby driving the sub-pixels to display.

[0051] Multiple traces can be set between the display area and the binding area. These traces are used to connect the binding components and sub-pixels to realize the transmission of driving signals.

[0052] It should be noted that the extension 212 can be in a flattened state or a bent state, and this application does not limit it in this regard.

[0053] like Figure 3 As shown, the main body 211 has a connecting area and corner areas B1 located on both sides of the connecting area. The main body 211 of the connecting area is connected to the extension 212. That is to say, in the arrangement direction of the connecting area and the corner area B1, the size of the main body 211 of the connecting area is the same as the size of the extension 212, and the area of ​​the main body 211 that extends beyond the extension 212 is the corner area B1.

[0054] like Figure 3 and Figure 4 As shown, the sidewall of the main body 211 of the corner area B1 facing the extension 212 is the first sidewall 211a, and the surface of the first sidewall 211a can be a plane, a curved surface, or a combination of a plane and a curved surface.

[0055] The first functional layer 22 is disposed on the side of the display panel 21 opposite to the light-emitting surface of the display module 2. The first functional layer 22 is bonded to the display panel 21 by a first adhesive layer (not shown in the figure). The surface of the first adhesive layer near the display panel 21 is in contact with the display panel 21, and the surface of the first adhesive layer near the first functional layer 22 is in contact with the first functional layer 22. The first functional layer 22 can be a single layer or a combination of multiple film layers such as a backplate layer 221, a buffer layer 223, and a conductive layer 222. This application does not limit this.

[0056] The first adhesive layer is an adhesive with bonding properties, such as optical adhesive or pressure-sensitive adhesive, but is not limited to these.

[0057] The sidewall of the first functional layer 22 corresponding to the corner area B1 and facing the extension 212 is the second sidewall 22a. The surface of the second sidewall 22a can be a plane, a curved surface, or a combination of a plane and a curved surface.

[0058] like Figure 1 As shown, during the testing of the touch function of the display screen 12, a copper rod 11 is typically used to rub along the light-emitting surface of the display screen 12. The rubbing trajectory can be a closed pattern along the edge area of ​​the display screen 12. Bright spots 13 are generated during the rubbing process of the copper rod 11. Figure 2 A photograph of bright spot 13 is shown. Bright spot 13 will affect the display effect of display panel 21.

[0059] The inventors of this application discovered through research that the bright spots 13 are caused by static electricity generated during the friction process entering the display panel 21, resulting in the lighting of sub-pixels within the display panel 21. The corner area B1 is more prone to static electricity concentration and thus more likely to produce bright spots 13 compared to other areas. Therefore, in the embodiments of this application, by covering the sidewall of the first adhesive layer between the first sidewall 211a and the second sidewall 22a of the corner area B1 with a first insulating portion 24, the first insulating portion 24 can prevent static electricity from entering the display panel 21 along the first adhesive layer between the display panel 21 and the first functional layer 22. When static electricity cannot enter the display panel 21, bright spots 13 will not appear on the display panel 21.

[0060] The first insulating part 24 is made of insulating material, which can prevent static electricity from being conducted into the display panel 21. The impedance of the first insulating part 24 can be greater than or equal to 1*10. 15 ohm.

[0061] In some embodiments, the first insulating portion 24 may be an insulating adhesive, such as ultraviolet light curing adhesive (UV adhesive), but is not limited thereto. The first insulating portion 24 may be manufactured using processes such as coating or bonding.

[0062] Experiments have shown that, in the same length of copper rod 11 friction process, the embodiments of this application are less likely to produce bright spots 13 compared to the comparative example without the first insulating part 24.

[0063] Alternatively, as Figure 3 and Figure 4 As shown, the display module 2 also includes a second insulating portion 25, which is disposed on the side of the display panel 21 away from the first functional layer 22. The second insulating portion 25 covers at least one end of the extension 212 near the main body portion 211. The impedance of the first insulating portion 24 is greater than or equal to the impedance of the second insulating portion 25.

[0064] The second insulating part 25 is made of insulating material, such as UV-curable adhesive. UV adhesive has an insulating effect and can provide electrostatic protection for the extension part 212, preventing the wiring inside the extension part 212 from being damaged by electrostatic discharge. It can also isolate water and oxygen, preventing water and oxygen from entering the display panel 21 and causing the display panel 21 to fail.

[0065] The impedance of the first insulating part 24 is greater than or equal to the impedance of the second insulating part 25. Therefore, compared with the connection area, static electricity is less likely to enter the display panel 21 of the corner area B1, thus preventing the appearance of bright spots 13 on the display panel 21 of the corner area B1.

[0066] Alternatively, as Figure 3 and Figure 4 As shown, the display module 2 also includes a second functional layer 23. The second functional layer 23 is disposed on the side of the display panel 21 away from the first functional layer 22. The orthographic projection of the second functional layer 23 on the main body 211 is located inside the main body 211. The sidewall of the second functional layer 23 corresponding to the corner area B1 facing the extension 212 is a third sidewall 23a. The third sidewall 23a is spaced apart from the first sidewall 211a. The second insulating part 25 extends to the connection area and covers at least a portion of the main body 211 of the connection area. The second insulating part 25 covers at least a portion of the main body 211 of the corner area B1. The first insulating part 24 covers the first sidewall 211a and is in contact with the second insulating part 25.

[0067] In some embodiments, the second functional layer 23 may be one or more layers of a polarizer 231, a protective film, etc. The protective film may be made of materials such as polyimide or polyethylene terephthalate.

[0068] The second functional layer 23 may be bonded to the display panel 21 by a second adhesive layer (not shown in the figure). The surface of the second adhesive layer near the display panel is in contact with the display panel 21, and the surface of the second adhesive layer near the second functional layer 23 is in contact with the second functional layer 23.

[0069] It should be noted that when the display panel 21 is an OLED panel, the sub-pixel includes an anode, a light-emitting material layer, and a cathode stacked sequentially. The cathode is located on the side of the anode furthest from the first functional layer 22, i.e., on the side of the anode closest to the second functional layer 23. The anode provides holes, and the cathode provides electrons. Holes and electrons recombine in the light-emitting material layer to emit light. The cathode material can be a conductive material, such as magnesium, silver, or other metallic materials. The cathode can be a single layer or a patterned layer. When static electricity enters the second adhesive layer between the display panel 21 and the second functional layer 23, the cathode can shield the electric field, preventing static electricity accumulation that could lead to bright spots 13.

[0070] Therefore, the first insulating portion 24 can only cover the sidewall of the first adhesive layer between the display panel 21 and the first functional layer 22, without covering the sidewall of the second adhesive layer between the display panel 21 and the second functional layer 23.

[0071] In some embodiments, the second insulating portion 25 may extend to the connection area and cover at least a portion of the main body portion 211 of the connection area. With the above arrangement, the second insulating portion 25 can provide electrostatic protection and isolate water and oxygen from the main body portion 211.

[0072] In some embodiments, the second insulating portion 25 may cover the second adhesive layer between the second functional layer 23 of the connection area and the display panel 21, further reducing the risk of static electricity entering the display panel 21 and reducing the static electricity from causing electrostatic damage to the circuits and other components within the display panel 21.

[0073] In some embodiments, the second insulating portion 25 may cover at least a portion of the main body portion 211 of the connection area and at least a portion of the main body portion 211 of the corner area B1, thereby increasing the area of ​​electrostatic protection and improving the protection effect on the display panel 21.

[0074] In some embodiments, the first insulating portion 24 covers the first sidewall 211a and extends into and contacts the second insulating portion 25 in the corner area B1. This arrangement allows the first insulating portion 24 to wrap around the first sidewall 211a, further increasing the area of ​​electrostatic protection.

[0075] In some embodiments, the material of the first insulating portion 24 is the same as the material of the second insulating portion 25, and the first insulating portion 24 and the second insulating portion 25 can be integrally formed.

[0076] Alternatively, as Figure 3 and Figure 4 As shown, the display module 2 also includes a cover plate 26 disposed on the side of the second functional layer 23 facing away from the display panel 21. The edge of the cover plate 26 extends beyond the edge of the display panel 21, and the first insulating portion 24 abuts against the surface of the cover plate 26 near the display panel 21. That is to say, the first insulating portion 24 covers the sidewall of the first adhesive layer between the first sidewall 211a and the second sidewall 22a, and the first insulating portion 24 covers the first sidewall 211a and extends to the surface of the cover plate 26 near the display panel 21, and the first insulating portion 24 contacts the cover plate 26. Through the above arrangement, the first insulating portion 24 can protect the sidewall of the multilayer film layer in the corner area B1, preventing static electricity from entering the display panel 21 along the adhesive layer between any film layers.

[0077] Alternatively, as Figure 6As shown, the first insulating portion 24 is continuously disposed along the periphery of the display panel 21 and covers the sidewall of the first adhesive layer between the sidewall of the first functional layer 22 and the sidewall of the display panel 21. That is to say, except for the sidewall corresponding to the connection area, the first insulating portion 24 can be continuously disposed on the remaining sidewalls of the display panel 21, thereby further reducing the risk of static electricity entering the display panel 21.

[0078] Alternatively, as Figure 3 and Figure 4 As shown, the first functional layer 22 includes a back panel layer 221, which is bonded to the display panel 21 by a first adhesive layer. The material of the back panel layer 221 is an insulating material. The sidewall of the back panel layer 221 in the corner area B1 is flush with the first sidewall 211a. The first insulating part 24 covers at least part of the sidewall of the back panel layer 221.

[0079] The back panel layer 221 is bonded to the display panel 21 by a first adhesive layer. That is to say, the surface of the first adhesive layer near the display panel 21 is in contact with the display panel 21, and the surface of the first adhesive layer near the back panel layer 221 is in contact with the back panel layer 221.

[0080] In some embodiments, the material of the back panel layer 221 includes one or more of silicon dioxide, polyester resin, polyethylene, polypropylene, polystyrene, polylactic acid, polyethylene terephthalate, polyimide, or polyurethane, but is not limited thereto. The back panel layer 221 can prevent the display panel 21 from being damaged by external forces and can block water and oxygen.

[0081] By making the sidewall of the backplate layer 221 flush with the first sidewall 211a, the attachment area of ​​the first insulating part 24 can be increased, and the manufacturing difficulty of the first insulating part 24 can be reduced.

[0082] Alternatively, as Figure 3 and Figure 4 As shown, the first functional layer 22 also includes a conductive layer 222, which is disposed on the side of the back plate layer 221 away from the main body 211. The impedance of the conductive layer 222 is less than the impedance of the back plate layer 221.

[0083] In some embodiments, the conductive layer 222 may be a conductive material. Conductive materials include copper, aluminum, stainless steel, etc.

[0084] When static electricity is conducted along the surface of the first insulating portion 24 away from the center of the display panel 21 to the conductive layer 222, the conductive layer 222 can conduct away the static electricity and prevent the accumulation of static electricity.

[0085] In some embodiments, the first functional layer 22 may further include a buffer layer 223 disposed between the backsheet layer 221 and the conductive layer 222. The buffer layer 223 may be made of at least one of foam, rubber, silicone, and plastic. The buffer layer 223 can provide shock absorption and prevent external stress from damaging the display panel 21.

[0086] Alternatively, as Figure 3 and Figure 5 As shown, the display module 2 includes a light-transmitting hole 27 that penetrates the display panel 21 and the first functional layer 22. A third insulating part 28 is provided on the side wall of the light-transmitting hole 27. The third insulating part 28 at least covers the side wall of the first adhesive layer between the display panel 21 and the first functional layer 22 inside the light-transmitting hole 27. The third insulating part 28 and the first insulating part 24 are made of the same material.

[0087] The light-transmitting hole 27 allows light to enter from the light-emitting side of the display panel 21 to the side of the display panel 21 opposite to the light-emitting direction. An optical sensor, camera, etc., can be correspondingly installed at the light-transmitting hole 27. The optical sensor at the light-transmitting hole 27 can be used for fingerprint recognition, etc. The camera can be a front-facing camera.

[0088] It should be noted that the light-transmitting hole 27 can penetrate the display panel 21 and the first functional layer 22, but the light-transmitting hole 27 does not penetrate the film layer furthest from the display panel 21 in the light-emitting direction, thereby preventing dust and other particles from entering the display panel 21 along the light-transmitting hole 27.

[0089] For example, when the film layer furthest from the display panel 21 in the light-emitting direction is the cover plate 26, the light-transmitting hole 27 does not penetrate the cover plate 26.

[0090] In some embodiments, such as Figure 3 and Figure 5 As shown, when the display module 2 includes a second functional layer 23 and a cover plate 26 disposed on the side of the second functional layer 23 away from the display panel 21, the light-transmitting hole 27 can penetrate the second functional layer 23 but not the cover plate 26.

[0091] At the light-transmitting hole 27, static electricity can be conducted along the sidewall of the light-transmitting hole 27 and enter the display panel 21. To prevent bright spots 13 from appearing on the display panel 21 near the light-transmitting hole 27 due to static electricity, a third insulating portion 28 can be provided on the sidewall of the light-transmitting hole 27. The third insulating portion 28 covers the sidewall of the first adhesive layer between the display panel 21 and the first functional layer 22 inside the light-transmitting hole 27, thereby preventing bright spots 13 from appearing on the display panel 21 near the light-transmitting hole 27.

[0092] In some embodiments, the third insulating portion 28 may cover the entire sidewall of the light-transmitting hole 27, further reducing the risk of static electricity entering the display panel 21 along the sidewall of the light-transmitting hole 27.

[0093] In some embodiments, the third insulating portion 28 may fill the light-transmitting hole 27. In this case, the third insulating portion 28 is made of a transparent material to prevent the third insulating portion 28 from blocking light transmission.

[0094] In some embodiments, the material of the third insulating portion 28 may be a transparent insulating material, such as a UV-curable adhesive.

[0095] In some embodiments, the third insulating portion 28 and the first insulating portion 24 are made of the same material, so that the light-transmitting hole 27 and the main body portion 211 of the corner area B1 have the same insulating ability, preventing either of them from having a bright spot.

[0096] Optionally, the impedance of the first insulating part 24 is greater than or equal to 1*10. 15 ohm.

[0097] The following is combined Figure 7 The control experiment for the copper rod friction test applied for is described. For example... Figure 7 As shown, the horizontal axis represents multiple sets of experimental data, including four sets of experiments: Comparative Example 1, Comparative Example 2, Example 1, and Example 2. The vertical axis represents the test time, i.e., the display module 2 was subjected to continuous friction testing using a copper rod friction process until the test duration requirement was met.

[0098] In Comparative Example 1, the display module does not have any of the first insulating part 24, the second insulating part 25, or the third insulating part 28. In Comparative Example 2, the display module only has the third insulating part 28. In Example 1, the display module only has the first insulating part 24. In Example 2, the display module has both the first insulating part 24 and the second insulating part 25.

[0099] Comparative Example 1 used five display modules for the experiment, with one bar chart corresponding to one display module. When the copper rod friction process was continuously applied for 5 minutes, 5 minutes, 10 minutes, 15 minutes, and 10 minutes, bright spots appeared on the display modules. Comparative Example 2 used two display modules for the experiment, one of which showed a bright spot at 20 minutes, while the other did not show a bright spot at 30 minutes.

[0100] Example 1 showed a bright patch after 29 minutes, significantly extending the test time compared to Comparative Example 1 and meeting the test duration requirement. Example 2 showed no bright patch after 30 minutes, demonstrating a better improvement compared to Example 1.

[0101] According to the above comparative experiments, setting the first insulating part 24 can significantly extend the test time of the display module 2, meeting the copper rod friction test time requirements. Setting the third insulating part 28 can also extend the test time of the display module 2 to a certain extent. Furthermore, setting both the first insulating part 24 and the third insulating part 28 simultaneously ensures that no bright spots appear even after 30 minutes of copper rod friction, demonstrating a better improvement effect.

[0102] According to the second aspect of this application, such as Figure 8 As shown, a display terminal 3 is provided, including the display module 2 described above.

[0103] In this embodiment, as Figure 8 As shown, the display terminal 3 includes a display module 2 and a terminal body 4, which are combined into one unit.

[0104] In this embodiment, the display terminal 3 can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.

[0105] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.
