Description

Technical Field

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

[0002] With the continuous advancement of science and technology, more and more electronic devices with display functions are being widely used in people's daily lives and work, bringing great convenience to their daily routines and work. The main structure of electronic devices that realizes the display function is the display device.

[0003] Generally, the display device of an electronic device includes a display module and a support frame. In conventional display devices, the display module is usually glued and fixed to the support frame with an adhesive layer. After the adhesive layer has cured, it is not convenient to disassemble the display module. Summary of the Invention

[0004] In view of the above problems, this application provides a display device and an electronic device, the specific solutions of which are as follows:

[0005] The first aspect of this application provides a display device, comprising:

[0006] A support frame, comprising opposing first and second surfaces;

[0007] The display module is fixed to the first surface by an electro-adhesive layer;

[0008] The circuit board is located on the side of the support frame away from the display module;

[0009] The conductive component is located between the display module and the circuit board, and is electrically connected to the electro-adhesive layer.

[0010] The first conductive connector is used to electrically connect the circuit board and the conductive component. The first conductive connector abuts against at least one of the circuit board and the conductive component. The circuit board provides a set voltage to the electro-adhesive layer through the first conductive connector.

[0011] In the display device provided by this application, the support frame has a first surface and a second surface facing each other. The display module is fixed to the first surface by an electro-adhesive layer. By providing a set voltage to the electro-adhesive layer through a circuit board, the loss of adhesion of the electro-adhesive layer can be controlled, thus facilitating the disassembly of the display module. Since the circuit board is located on the side of the support frame away from the display module, it is not necessary to disassemble the circuit board while disassembling the display module, avoiding the impact of disassembly of the display module on the reliability of the circuit board.

[0012] Furthermore, the electro-adhesive layer is electrically connected to the conductive component, and the circuit board is electrically connected to the conductive component via a first conductive connector. This allows the circuit board to provide a set voltage to the electro-adhesive layer during display module disassembly, controlling the loss of adhesion of the electro-adhesive layer. Since the first conductive connector abuts against at least one of the circuit board and the conductive component, the abutting pressure at the abutting position naturally dissipates after the display module is disassembled, thereby achieving separation at the abutting position and realizing non-destructive separation between the circuit board and the conductive component. Compared to the solution where the circuit board and the electro-adhesive layer are electrically connected via soldering, the technical solution of this application eliminates the need for destructive disassembly of the circuit structure between the circuit board and the electro-adhesive layer during display module disassembly, facilitating non-destructive disassembly of the circuit structure connected to the circuit board.

[0013] A second aspect of this application also provides an electronic device, including the aforementioned display device.

[0014] As can be seen from the above description, the electronic device provided in this application embodiment adopts the above-mentioned display device, which facilitates the disassembly of the display module and the circuit board. Attached Figure Description

Detailed Implementation

[0039] The embodiments of this application will now be clearly and completely described with reference to the accompanying drawings. Those skilled in the art will recognize that, with technological advancements and the emergence of new scenarios, the technical solutions provided in the embodiments of this application are equally applicable to similar technical problems.

[0040] As described in the background section, in conventional display devices, the method of bonding and fixing the display module to the support frame with ordinary adhesive is not convenient for disassembling the display module.

[0041] The inventors discovered that when the display module and the support frame are bonded and fixed by an electro-adhesive layer, a set voltage can be applied to the electro-adhesive layer through a circuit board to control the loss of adhesion, thereby enabling simple disassembly of the display module and facilitating the disassembly of the display module and the support frame.

[0042] When using an electro-adhesive layer to bond and fix the display module to the support frame, if the circuit board is fixed to the surface of the display module facing the support frame, it needs to be electrically connected to the electro-adhesive layer by soldering. Disassembling the display module requires destructive removal of the circuit structure between the circuit board and the electro-adhesive layer, making circuit board removal inconvenient.

[0043] In view of this, embodiments of this application provide a display device, including:

[0044] A support frame, the support frame including opposing first and second surfaces;

[0045] The display module is fixed to the first surface by an electro-adhesive layer;

[0046] The circuit board is located on the side of the support frame away from the display module;

[0047] A conductive component is located between the display module and the circuit board, and is electrically connected to the electro-adhesive layer.

[0048] A first conductive connector is provided, wherein the circuit board and the conductive component are electrically connected through the first conductive connector, and the first conductive connector abuts against at least one of the circuit board and the conductive component; the circuit board provides a set voltage to the electro-adhesive layer through the first conductive connector.

[0049] In this embodiment, a display module and a circuit board are respectively disposed on opposite sides of the support frame. The display module and the support frame are bonded and fixed together by an electro-adhesive layer. A set voltage can be provided to the electro-adhesive layer through the circuit board to cause the electro-adhesive layer to lose its adhesion, thus facilitating the disassembly of the display module.

[0050] Since the circuit board is located on the side of the support frame away from the display module, it is not necessary to disassemble the circuit board when removing the display module, thus avoiding the impact of disassembling the display module on the reliability of the circuit board.

[0051] Furthermore, the electro-adhesive layer is electrically connected to the conductive component, and the circuit board is electrically connected to the conductive component via a first conductive connector. This allows the circuit board to provide a set voltage to the electro-adhesive layer during display module disassembly, controlling the loss of adhesion of the electro-adhesive layer. Since the first conductive connector abuts against at least one of the circuit board and the conductive component, the abutting pressure at the abutting position naturally dissipates after the display module is disassembled, thereby achieving separation at the abutting position and realizing non-destructive separation between the circuit board and the conductive component. Compared to the solution where the circuit board and the electro-adhesive layer are electrically connected via soldering, the technical solution of this application eliminates the need for destructive disassembly of the circuit structure between the circuit board and the electro-adhesive layer during display module disassembly, facilitating non-destructive disassembly of the circuit structure connected to the circuit board.

[0052] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0053] refer to Figure 1 , Figure 1 This application provides a schematic diagram of the structure of a display device, which includes:

[0054] The support frame 100 includes a first surface 101 and a second surface 102 opposite to each other.

[0055] Display module 103 is fixed to the first surface 101 by an electro-adhesive layer 104;

[0056] Circuit board 105 is located on the side of the support frame 100 away from the display module 103;

[0057] The conductive element 106 is located between the display module 103 and the circuit board 105, and is electrically connected to the electro-adhesive layer 104.

[0058] The first conductive connector 107 is used to electrically connect the circuit board 105 and the conductive element 106. The first conductive connector 107 abuts against at least one of the circuit board 105 and the conductive element 106. The circuit board 105 provides a set voltage to the electro-adhesive layer 104 through the first conductive connector 107.

[0059] The circuit board can be fixed to the second surface 102 by means of screws or clips.

[0060] In one embodiment, the lower end of the first conductive connector 107 can be fixed to the circuit board 105, and the upper end of the first conductive connector 107 is a free end that abuts against the conductive member 106. In this method, after the display module 103 is bonded to the first surface 101 by the electro-adhesive layer 104, based on the display module 103 bonded to the support frame 100, the conductive member 106 can apply pressure to the upper end of the first conductive connector 107, so that the conductive member 106 abuts against the upper end of the first conductive connector 107. When the display module 103 is removed, this pressure is released, thereby separating the conductive member 106 from the upper end of the first conductive connector 107.

[0061] In another embodiment, the upper end of the first conductive connector 107 is fixed to the conductive member 106, and the lower end of the first conductive connector 107 is a free end that abuts against the circuit board 105. In this embodiment, after the display module 103 is bonded to the first surface 101 by the electro-adhesive layer 104, the display module 103, bonded to the support frame 100, can compress the first conductive connector 107, causing the lower end of the first conductive connector 107 to apply pressure to the circuit board 105, thereby causing the lower end of the first conductive connector 107 to abut against the circuit board 105. When the display module 103 is removed, this pressure is released, thereby causing the lower end of the first conductive connector 107 to separate from the circuit board 105.

[0062] In another embodiment, both the upper and lower ends of the first conductive connector 107 are free ends. When the display module 103 and the circuit board 105 are respectively fixed to the first surface 101 and the second surface 102, the display module 103 presses against the conductive member 106, causing the conductive member 106 and the circuit board 105 to press against the first conductive connector 107 between them. This causes the upper end of the first conductive connector 107 to abut against the conductive member 106, and the lower end of the first conductive connector 107 to abut against the circuit board 105. After the display module 103 is disassembled, the pressing force of the conductive member 106 and the circuit board 105 on the first conductive connector 107 is released, allowing the lower end of the first conductive connector 107 to separate from the circuit board 105, and the upper end of the first conductive connector 107 to separate from the conductive member 106.

[0063] If one end of the first conductive connector 107 is fixedly connected to the opposite structural component, it can be done by screws or welding.

[0064] In the display device provided in this application embodiment, the display module 103 and the support frame 100 are bonded and fixed by an electro-adhesive layer 104. A set voltage can be provided to the electro-adhesive layer by the circuit board 105 to make the electro-adhesive layer 104 lose its adhesion, thereby facilitating the disassembly of the display module 103.

[0065] On the other hand, since the circuit board 105 and the display module 103 are respectively located on opposite sides of the support frame 100, the circuit board does not need to be disassembled when the display module 103 is disassembled, which can avoid the disassembly of the display module 103 affecting the reliability of the circuit board.

[0066] Furthermore, since the first conductive connector 107 abuts against at least one of the circuit board 105 and the conductive component 106, after the display module 103 is disassembled, as the display module 103 separates from the support frame 100, the pressure applied at the abutment position can be removed simultaneously, thereby allowing the first conductive connector 107 to naturally separate from the relative structural component at the abutment position, so as to achieve non-destructive separation between the circuit board 105 and the conductive component 106, without the need for destructive disassembly of the circuit structure between the circuit board 105 and the electro-adhesive layer 104, which facilitates non-destructive disassembly of the circuit structure connected to the circuit board 105.

[0067] refer to Figure 2 , Figure 2This is a schematic diagram of another display device provided in an embodiment of this application. Based on other embodiments, the support frame 100 includes a side surface 109 connecting the first surface 101 and the second surface 102; the electro-adhesive layer 104 includes a bent portion 108, which extends from the side surface 109 to the second surface 102, and the bent portion 108 partially overlaps with the second surface 102; there is a first preset distance D1 between the bent portion 108 on the second surface 102 and the circuit board 105; the conductive element 106 includes a bent portion 108, and a first conductive connector 107 is located between the bent portion 108 and the circuit board 105.

[0068] Optionally, such as Figure 2 As shown, a conductive plate 110 is provided on the side surface of the display module 103 facing the support frame 100. The display module 103 is bonded and fixed to the electro-adhesive layer 104 through the conductive plate 110. A second conductive connector 111 is connected between the circuit board 105 and the conductive plate 110. The second conductive connector 111 and the first conductive connector 107 are respectively connected to different positions of the electro-adhesive layer 104. In this way, the circuit board 105 can apply a set voltage to different positions of the electro-adhesive layer 104 through the second conductive connector 111 and the first conductive connector 107.

[0069] exist Figure 2 In the illustrated manner, the electro-adhesive layer 104 can be folded onto the second surface 102 based on the bending portion 108, and a first conductive connector 107 is provided based on the first preset distance D1 between the bending portion 108 on the second surface 102 and the circuit board 105, so as to realize the electrical connection between the circuit board 105 and the electro-adhesive layer 104.

[0070] refer to Figure 3 , Figure 3 This is a schematic diagram of another display device provided in the embodiments of this application. Based on other implementation methods, Figure 3 The display device also includes: a conductive strip 112 located on the side of the display module 103 facing the support frame 100, the conductive strip 112 being electrically connected to the electro-adhesive layer 104; a conductive component 106 including the conductive strip 112; a second preset distance D2 between the conductive strip 112 and the circuit board 105; and a first conductive connector 107 located between the conductive strip 112 and the circuit board 105.

[0071] Optionally, with Figure 2 The method shown is the same, in Figure 3In the illustrated configuration, a conductive plate 110 is provided on the surface of the display module 103 facing the support frame 100. The display module 103 is bonded and fixed to the electro-adhesive layer 104 via the conductive plate 110. A second conductive connector 111 connects the circuit board 105 to the conductive plate 110. The second conductive connector 111 and the first conductive connector 107 are respectively connected to different positions of the electro-adhesive layer 104. In this way, the circuit board 105 can apply a set voltage to different positions of the electro-adhesive layer 104 via the second conductive connector 111 and the first conductive connector 107.

[0072] exist Figure 3 In the illustrated configuration, the electro-adhesive layer 104 can be electrically connected to the first conductive connector 107 based on the conductive strip 112. The first conductive connector 107 is provided based on the second preset distance D2 between the conductive strip 112 and the circuit board 105, so as to facilitate the electrical connection between the circuit board 105 and the electro-adhesive layer 104.

[0073] Optionally, such as Figure 3 As shown, the surface of the display module 103 facing away from the display side is fixed to the conductive plate 110; the conductive plate 110 is fixed to the first surface 101 based on the electro-adhesive layer 104 and is electrically connected to the electro-adhesive layer 104; the conductive plate 110 is insulated from the conductive strip 112, such that the side of the conductive strip 112 facing the conductive plate 110 has an insulating adhesive layer (i.e., the second insulating adhesive layer 113 hereinafter), so that the conductive strip 112 is insulated from the conductive plate 110. The conductive plate 110 can be a metal plate or an insulating plate with a conductive layer on its surface, etc.

[0074] The circuit board 105 includes a positive terminal N+ and a negative terminal N- for connecting a power supply circuit. One of the positive terminal N+ and the negative terminal N- is electrically connected to a first conductive connector 107, and the other is electrically connected to one end of a second conductive connector 111. The other end of the second conductive connector 111 is electrically connected to a conductive plate 110. The second conductive connector 111 abuts against at least one of the circuit board 105 and the conductive plate 110. The circuit board 105 can apply a predetermined voltage at different locations on the electro-adhesive layer 104 via the second conductive connector 111 and the first conductive connector 107.

[0075] Figure 3 In the illustrated configuration, the first conductive connector 107 is connected to the negative terminal N- and the second conductive connector 111 is connected to the positive terminal N+. In other configurations, the first conductive connector 107 can be connected to the positive terminal N+ and the second conductive connector 111 can be connected to the negative terminal N-.

[0076] Since the second conductive connector 111 abuts against at least one of the circuit board 105 and the conductive plate 110, when the display module 103 is disassembled, after the display module 103 is separated from the support frame 100 through the electro-adhesive layer 104, the circuit board 105 and the conductive plate 110 can be separated without damage at the abutment position. There is no need to destructively disassemble the circuit structure between the circuit board 105 and the conductive plate 110, which facilitates the non-destructive disassembly of the circuit structure connected to the circuit board 105.

[0077] In one configuration, the upper end of the second conductive connector 111 can be fixed relative to the conductive plate 110, and the lower end of the second conductive connector 111 can abut against the circuit board 105; alternatively, the upper end of the second conductive connector 111 abuts against both the conductive plate 110 and the circuit board 105. In this configuration, since the lower end of the second conductive connector 111 needs to be precisely aligned point-to-point with the negative terminal N- or positive terminal N+ of the circuit board 105 to achieve accurate electrical connection and fixation, high alignment precision is required.

[0078] Optionally, the end of the second conductive connector 111 facing the circuit board 105 is fixed to the circuit board 105, and the end facing the conductive plate 110 abuts against the conductive plate 110. For example... Figure 3 As shown, in this method, the lower end of the second conductive connector 111 can be fixed to the circuit board 105 and electrically connected to the negative terminal N- or the positive terminal N+, while the upper end of the second conductive connector 111 abuts against the conductive plate 110. In this way, the lower end of the second conductive connector 111 and the circuit board 105 are fixed point-to-point, allowing for pre-alignment of the lower end of the second conductive connector 111 with the negative terminal N- or the positive terminal N+ of the circuit board 105, achieving accurate electrical connection. The upper end of the second conductive connector 111 abuts against the conductive plate 110 point-to-surface, meaning any position on the lower surface of the conductive plate 110 can abut against the upper end of the second conductive connector 111, reducing the alignment accuracy of the second conductive connector 111 at the abutment position during the assembly of the display components.

[0079] refer to Figure 4 , Figure 4 This is a schematic diagram of another display device provided in the embodiments of this application. Based on other implementation methods, Figure 4 In the display device shown, the display module 103 is fixed to the conductive plate 110 on the surface opposite to the display side. The conductive plate 110 is fixed to the first surface 101 based on the electro-adhesive layer 104 and is electrically connected to the electro-adhesive layer 104. The conductive plate 110 is insulated from the conductive strip 112, such that the side of the conductive strip 112 facing the conductive plate 110 has an insulating adhesive layer (i.e., the second insulating adhesive layer 113 hereinafter).

[0080] exist Figure 4In the configuration shown, the support frame 100 is a metal frame; the circuit board 105 includes a positive terminal N+ and a negative terminal N- for connecting the power supply circuit; one of the positive terminal N+ and the negative terminal N- is electrically connected to the first conductive connector 107, and the other is electrically connected to the metal frame. Figure 4 In this example, the metal frame is electrically connected to the negative terminal N- and the first conductive connector 107 is electrically connected to the positive terminal N+. In other cases, the metal frame can be electrically connected to the positive terminal N+ and the first conductive connector 107 can be electrically connected to the negative terminal N-.

[0081] like Figure 4 As shown, the metal frame is also electrically connected to the conductive plate 110. Thus, one of the positive terminal N+ and the negative terminal N- is sequentially electrically connected to one location of the electro-adhesive layer 104 via the metal frame and the conductive plate 110, while the other is sequentially electrically connected to another location of the electro-adhesive layer 104 via the first conductive connector 107 and the conductive strip 112. This allows a set voltage to be provided to the electro-adhesive layer 104 based on these two different locations. Optionally, the metal frame and the conductive plate 110 are electrically connected via a third conductive connector 114.

[0082] exist Figure 4 In the illustrated configuration, a metal frame can be used as a circuit connection structure for an electrical electrode, eliminating the need for a second conductive connector 111. The set voltage for the electro-adhesive layer 104 can be provided solely through the first conductive connector 107.

[0083] In some embodiments of this application, such as Figure 4 As shown, the metal frame has a first region 115 and a second region 116. In the first region 115, the metal frame and the conductive plate 110 are bonded together by an electro-adhesive layer 104, and a first insulating adhesive layer 117 is provided between the electro-adhesive layer 104 and the metal frame. In the second region 116, the metal frame and the conductive plate 110 are electrically connected based on a third conductive connector 114, which abuts against at least one of the conductive plate 110 and the first surface 101. Optionally, the first insulating adhesive layer 117 may be a pressure-sensitive adhesive (PSA).

[0084] When the metal frame is used as the circuit structure connected to the circuit board 105 to supply power to the electro-adhesive layer 104, and the conductive plate 110 is electrically connected to the metal frame through the third conductive connector 114, the third conductive connector 114 is set to abut against at least one of the conductive plate 110 and the first surface 101. When the display module 103 is disassembled, after the display module 103 is separated from the metal frame 100, the third conductive connector 114 can be separated synchronously until it abuts, which facilitates the non-destructive separation of the circuit structure between the conductive plate 110 and the metal frame.

[0085] Optionally, the third conductive connector 114 abuts against one of the conductive plate 110 and the first surface 101, and is fixedly connected to the other. In this configuration, one end of the third conductive connector 114 is fixed, and the other end abuts against the opposing structural component. During the installation and disassembly of the display module 103, one end of the third conductive connector 114 can be fixed to prevent it from falling off and being lost, while also facilitating the installation and disassembly of structural components in the display device.

[0086] refer to Figure 5 , Figure 5 This is a schematic diagram of another display device provided in the embodiments of this application. Based on other implementation methods, Figure 5 In the display device shown, the first surface 101 has a groove 118; the electro-adhesive layer 104 includes: a first portion 119 located within the groove 118 and a second portion 120 located outside the groove; in a direction perpendicular to the plane of the display device ( Figure 5 In the vertical direction, the first part 119 has an overlapping area with the conductive strip 112 and is electrically connected to the conductive strip 112 in the overlapping area; the second part 120 has no overlapping area with the conductive strip 112 and is bonded and fixed to the display module 103.

[0087] exist Figure 5 In the illustrated configuration, the first portion 119 is accommodated by the groove 118, thereby creating a height difference between the first portion 119 and the second portion 120. The second portion 120 has a greater height to facilitate the electrical connection between the first portion 119 and the conductive strip 112 based on this height difference. The upper surface of the second portion 120 can be flush with and fixed to the same surface as the conductive strip 112. When there is no conductive plate 110 on the back of the display module 103, this surface can be the back of the display module 103. When the back of the display module 103 is provided with a conductive plate 110, this surface can be the back of the conductive plate 110. Thus, a uniformly thick electro-adhesive layer 104 is bent into... Figure 5 The Z-shaped structure shown can be adapted to the graphic structure of the groove 118, allowing the display module 103 to be bonded to the first surface 101 without the need for... Figure 4 The method shown uses an electro-adhesive layer 104 with uneven thickness, and does not require... Figure 2 The electro-adhesive layer 104 is bent onto the second surface 102, which reduces the assembly process difficulty of the display device.

[0088] When a groove 118 is provided on the first surface 101, it is possible to Figure 3 Based on the display device shown Figure 5 The circuit connection design shown indicates that the circuit board 105 is connected to different positions of the electro-adhesive layer 104 via the first conductive connector 107 and the second conductive connector 111.

[0089] refer to Figure 6 , Figure 6 This is a schematic diagram of another display device provided in the embodiments of this application. Based on other implementation methods, Figure 6 In the display device shown, when a groove 118 is provided on the first surface 101, it is possible to... Figure 4 Based on the display device shown Figure 6 The circuit connection design shown shows that the circuit board 105 is connected to different positions of the electro-adhesive layer 104 through the first conductive connector 107 and the metal frame.

[0090] In some embodiments of this application, such as Figure 5 or Figure 6 In one embodiment, the surface of the display module 103 facing away from the display side is fixed to a conductive plate 110, which is fixed to a first surface 101 based on an electro-adhesive layer 104. The conductive plate 110 is electrically connected to the electro-adhesive layer 104 and insulated from the conductive strip 112. A first portion 119 is electrically connected to the conductive strip 112, and a second portion 120 is electrically connected to the conductive plate 110. In this embodiment, the conductive plate 110 and the conductive strip 112 can be electrically connected to different positions of the electro-adhesive layer 104, and the circuit board 105 can apply a set voltage to different positions of the electro-adhesive layer 104 through the conductive plate 110 and the conductive strip 112.

[0091] Optionally, such as Figure 5 or Figure 6 In one embodiment, the first part 119 and the conductive strip 112 are electrically connected via a fourth conductive connector 121, which abuts against at least one of the first part 119 and the conductive strip 112. In this embodiment, a gap is formed between the first part 119 and the conductive strip 112 based on the groove 118, and the fourth conductive connector 121 is positioned based on this gap to electrically connect the first part 119 and the conductive strip 112, facilitating the circuit connection between the first part 119 and the conductive strip 112. Furthermore, since the fourth conductive connector 121 abuts against at least one of the first part 119 and the conductive strip 112, and the conductive strip 112 is fixed to the display module 103, when disassembling the display module 103, the fourth conductive connector 121 can be simultaneously and non-destructively separated until it abuts, achieving non-destructive separation of the circuit connection structure between the first part 119 and the conductive strip 112.

[0092] In some implementations, such as Figure 5 or Figure 6In any embodiment, the fourth conductive connector 121 is bonded and fixed to the first portion 119 on the side facing the first portion 119, and abuts against the conductive strip 112 on the side facing the conductive strip 112. In this embodiment, the lower surface of the fourth conductive connector 121 can be directly bonded and fixed to the first portion 119 based on the electro-adhesive layer 104, without additional adhesive layer. The upper surface of the fourth conductive connector 121 abuts against the conductive strip 112 based on the pressing force after the display module 103 is installed, which facilitates the installation and disassembly of structural components in the display device.

[0093] In some implementations, such as Figures 3-6 In any embodiment, the surface of the display module 103 facing away from the display side is fixed to the conductive plate 110, and the conductive plate 110 is bonded to the first surface 101 based on the electro-adhesive layer 104; the conductive plate 110 and the electro-adhesive layer 104 are electrically connected; the conductive strip 112 is fixed to the surface of the conductive plate 110 through the second insulating adhesive layer 113 so that the conductive strip 112 is insulated from the conductive plate 110. Optionally, the second insulating adhesive layer 113 can be an insulating double-sided adhesive.

[0094] refer to Figure 7 , Figure 7 This is a partial enlarged view of the conductive strip area of ​​a display device provided in an embodiment of this application. Based on other embodiments, Figure 7 In the display device shown, the surface of the conductive strip 112 facing the support frame 100 is covered with an insulating layer 122. The insulating layer 122 exposes the area where the conductive strip 112 connects to the first conductive connector 107 and the area where it connects to the electro-adhesive layer 104. Figure 7 As shown, the insulating layer 122 has hollow areas in the upper region corresponding to the first conductive connector 107 and the upper region corresponding to the fourth conductive connector 121, so that the conductive strip 112 can be electrically connected to the upper end of the first conductive connector 107 and the upper end of the fourth conductive connector 121 in the corresponding hollow areas.

[0095] Optionally, the conductive strip 112 can be any one of a metal layer, a conductive oxide (such as ITO) layer, a graphene layer, a graphite layer, and a carbon nanotube layer. These materials have good electrical conductivity, which can not only effectively reduce circuit resistance, but also facilitate the formation of thin film structures, thereby reducing the impact on product thickness while reducing resistance.

[0096] like Figure 7 As shown, if the display module 103 is fixed on the conductive plate 110, the conductive strip 112 is fixed to the surface of the conductive plate 110 through the second insulating adhesive layer 113. If there is no conductive plate 110, the conductive strip 112 is fixed to the back of the display module 103 through the second insulating adhesive layer 113.

[0097] exist Figure 7 In the illustrated configuration, when the support frame 100 is a metal frame, by covering the surface of the conductive strip 112 facing the support frame 100 with an insulating layer 122, the spacing between the conductive strip 112 and the underlying metal frame can be reduced. This reduces the thickness of the display device while preventing short circuits between the conductive strip 112 and the metal frame. In some embodiments, based on other embodiments, such as... Figure 7 As shown, the support frame 100 is a metal frame; the electro-adhesive layer 104 is bonded and fixed to the first surface 101 by a first insulating adhesive layer 117, and a conductive layer 123 is also included between the first insulating adhesive layer 117 and the electro-adhesive layer 104. Based on the conductive layer 123, the circuit resistance can be reduced, thereby reducing the set voltage for controlling the loss of adhesion of the electro-adhesive layer 104 and reducing energy consumption.

[0098] In other solutions, if there is a large distance between the metal frame and the conductive strip 112, the risk of short circuit between the two is low, and the insulating layer 122 can be omitted, and the conductive strip 112 can be directly exposed.

[0099] Optionally, the conductive layer 123 includes any one of a metal layer, a composite conductive layer, a graphene layer, a graphite layer, and a carbon nanotube layer. These materials have good electrical conductivity, which can not only effectively reduce circuit resistance, but also facilitate the formation of thin film structures, thereby reducing the impact on product thickness while reducing resistance.

[0100] refer to Figure 8 , Figure 8 This is a schematic diagram of another display device provided in the embodiments of this application. Based on other implementation methods, Figure 8 In the display device shown, the surface of the display module 103 facing away from the display side is fixed to the conductive plate 110, and the conductive plate 110 is fixed to the first surface 101 based on the electro-adhesive layer 104. The support frame 100 is a metal frame, and the electro-adhesive layer 104 is electrically connected to the conductive plate 110 and the metal frame respectively. The conductive component 106 includes the conductive plate 110; the circuit board 105 includes a positive terminal N+ and a negative terminal N- of the power supply circuit; one of the positive terminal N+ and the negative terminal N- is connected to the first conductive connector 107, and the other is electrically connected to the metal frame. The first conductive connector 107 abuts against at least one of the conductive plate 110 and the circuit board 105.

[0101] exist Figure 8In the illustrated configuration, the circuit board 105 can reuse the metal frame as an electrode structure. A set voltage is applied to the two opposing surfaces of the electro-adhesive layer 104 via the metal frame and the first conductive connector 107, respectively, to control the loss of adhesion of the electro-adhesive layer 104 when the display module 103 is disassembled. This method eliminates the need for an additional adhesive layer (such as PSA mentioned earlier) between the electro-adhesive layer 104 and the metal frame. It not only reuses the metal frame as an electrode structure but also reduces the number of insulating adhesive layers, thus decreasing the product thickness.

[0102] Optionally, the electro-adhesive layer 104 can be in direct contact with the conductive plate 110 and the metal frame respectively, so as to realize the electrical connection between the electro-adhesive layer 104 and the conductive plate 110 and the metal frame.

[0103] When the metal frame is electrically connected to the circuit board 105, in some implementations, such as Figure 8 As shown, there is electrical contact between the metal frame and the circuit board 105. The circuit board 105 can be directly fixed to the metal frame by screws or clips, which not only realizes the electrical connection between the metal frame and the circuit board 105, but also facilitates the installation and removal of the circuit board 105 on the metal frame.

[0104] refer to Figure 9 , Figure 9 This is a schematic diagram of another display device provided in the embodiments of this application. Based on other implementation methods, Figure 9 In the display device shown, the metal frame and the circuit board 105 are electrically connected via a fifth conductive connector 124; the fifth conductive connector 124 abuts against at least one of the metal frame and the circuit board 105. In this manner, when it is necessary to remove the circuit board 105 from the metallized frame, after the circuit board 105 is separated from the metal frame, the fifth conductive connector 124 can be separated without damage at the abutment position, allowing for the non-destructive removal of the circuit structure connected to the edge of the circuit board 105.

[0105] refer to Figure 10 and Figure 11 , Figure 10 This is a top view of a display device provided in an embodiment of this application.

Figure 10 The top view of the display device shown only shows the support frame 100 and the electro-adhesive layer 104; other related structures can be described in other embodiments of this application.

[0106] Based on other implementation methods Figure 10 and Figure 11The display device shown includes multiple display modules 103, with the side of each display module 103 facing away from the display side fixed to the surface of an independent conductive plate 110. The conductive plates 110 are all fixed to a first surface 101 based on an electro-adhesive layer 104. In this configuration, multiple display modules 103 can be seamlessly and coplanarly fixed to the same side of a support frame 100 via the electro-adhesive layer 104, enabling the construction of a large-area spliced ​​display device.

Second conductive connector 111 connects conductive plate 110 and circuit board 105.

The relative positions of the support frame 100 and the electro-adhesive layer 104 are shown for clarity. Figure 10 The top view of the display device shown only shows the support frame 100, the electro-adhesive layer 104, and the conductive strip 112. Other related structures can be described in other embodiments of this application.

[0109] Based on other implementation methods Figure 10 and Figure 11 The display device shown includes multiple display modules 103, each fixed to the surface of an independent conductive plate 110 on the side opposite to the display side; the conductive plates 110 are all fixed to a first surface 101 based on an electro-adhesive layer 104. Figure 10 and Figure 11 The method shown is the same. Figure 12 and Figure 13 The method shown allows multiple display modules 103 to be seamlessly and coplanarly fixed to the same side of the support frame 100 via an electro-adhesive layer 104, enabling the construction of a large-area splicing display device.

[0110] Figure 12 and Figure 13In the illustrated configuration, a groove 118 is formed on the first surface 101. The electro-adhesive layer 104 includes a first portion 119 located within the groove 118 and a second portion 120 located outside the groove. The first portion 119 is connected to a conductive strip 112 on the back side of the conductive plate 110. The circuit board 105 provides a set voltage to the electro-adhesive layer 104 based on a first conductive connector 107 and a second conductive connector 111, respectively. The first conductive connector 107 connects the conductive strip 112 and the circuit board 105. The second conductive connector 111 connects the conductive plate 110 and the circuit board 105.

[0111] like Figures 10-13 As shown, when multiple display modules 103 are provided, and each display module 103 is fixed on a corresponding conductive plate 110, in some embodiments, the electro-adhesive layer 104 includes multiple insulating and isolating frames 125; the frames 125 correspond one-to-one with the conductive plates 110, are bonded and fixed to the periphery of the corresponding conductive plates 110, and are in electrical contact with the conductive plates 110; the circuit board 105 includes a positive terminal N+ and a negative terminal N- connected to the power supply circuit; each frame 125 is electrically connected to an independent conductive element 106. Each frame 125 corresponding to each display module 103 is connected to a first conductive connector 107 and a second conductive connector 111. For the first conductive connector 107 and the second conductive connector 111 corresponding to the same display module 103, one of the first conductive connector 107 and the second conductive connector 111 is electrically connected to the positive terminal N+, and the other is electrically connected to the negative terminal N-.

[0112] refer to Figures 14-16 , Figure 14 This is a top view of yet another display device provided in an embodiment of this application. Figure 15 for Figure 14 The image shown is a cross-sectional view of the display device in the Q-Q' direction. Figure 16 for Figure 14 The diagram shows another cross-sectional view of the display device in the Q-Q' direction. Wherein, Figure 15 The electro-adhesive layer 104 is connected to the first conductive connector 107 based on the bending portion 108. Figure 16 The electro-adhesive layer 104 is connected to the first conductive connector 107 based on the conductive strip 112.

[0113] Based on other implementation methods Figures 14-16In the display device shown, when multiple display modules 103 are provided, and each display module 103 is fixed on a corresponding conductive plate 110, each conductive plate 110 is bonded and fixed to the support frame 100 based on the same electro-adhesive layer 104. The electro-adhesive layer 104 includes multiple adhesive frames 125 corresponding to each conductive plate 110, and the adhesive frames 125 are bonded and fixed to the periphery of the corresponding conductive plate 110. Each adhesive frame 125 is an integral electrical connection structure, and the adhesive frame is in electrical contact with the corresponding conductive plate 110. The circuit board 105 includes a positive terminal N+ and a negative terminal N- connected to the power supply circuit; a first conductive connector 107 is electrically connected to the negative terminal N-; the circuit board 105 includes multiple positive terminals N+ corresponding to each conductive plate 110, and the positive terminals are electrically connected to the corresponding conductive plates 110 based on a second conductive connector 111; the second conductive connector 111 abuts against at least one of the circuit board 105 and the conductive plate 110.

[0114] When each display module 103 uses an integrated electrically connected frame 125, all display modules 103 are bonded and fixed to the support frame 100 using a single layer of electro-adhesive 104. Each display module 103 has an independent conductive plate 110. A first conductive connector 107 is electrically connected to the negative terminal N-, and the positive terminal is electrically connected to the corresponding conductive plate 110 via a second conductive connector 111. Thus, each display module 103 can be connected to a high level via its individual positive terminal N+, and all display modules 103 can be connected to a low level via the same negative terminal N-. All display modules 103 can share the same first conductive connector 107 and negative terminal N-. Only one first conductive connector 107 and one negative terminal N- are needed for each display module 103. This not only enables independent control of the loss of adhesion of the electro-adhesive 104 for each display module 103, but also reduces the number of first conductive connectors 107 and negative terminals N-.

[0115] refer to Figure 17 and Figure 18 , Figure 17 This is a top view of yet another display device provided in an embodiment of this application. Figure 18 for Figure 17 The diagram shows a cross-sectional view of the display device along the Q-Q' direction. The relative positions of the support frame 100 and the electro-adhesive layer 104 are shown for clarity. Figure 10 The top view of the display device shown only shows the support frame 100, conductive strip 112, third conductive connector 114 and electro-adhesive layer 104. Other related structures can be described in other embodiments of this application.

[0116] Based on other implementation methods Figure 17 and Figure 18In the display device shown, when multiple display modules 103 are provided, and each display module 103 is fixed to a corresponding conductive plate 110, the electro-adhesive layer 104 includes multiple insulating and isolating frames 125. Each frame 125 corresponds to a conductive plate 110 and is bonded and fixed to the periphery of the corresponding conductive plate 110, making electrical contact with the conductive plate 110. The circuit board 105 includes a positive terminal N+ and a negative terminal N- connected to the power supply circuit. Each frame 125 is electrically connected to an independent conductive element 106, and a first conductive connector 107 is electrically connected to a different positive terminal N+. The support frame 100 is a metal frame, and the metal frame is electrically connected to the negative terminal. This method is illustrated using the example of a conductive strip 112 as the conductive element 106.

[0117] Figure 17 and Figure 18 In the display device shown, a metal frame can be reused as an electrode structure and connected to the negative terminal N- to access the same low level. The adhesive frame 125 corresponding to each display module 103 can be individually input with a high level through a separate first conductive connector 107. Thus, the adhesive frame 125 corresponding to each display module 103 can be individually input with a set voltage to enable individual de-adhesion control of the adhesive frame 125 corresponding to each display module 103, allowing for individual disassembly of each display module 103.

[0118] refer to Figure 19 , Figure 19 This is a partially enlarged schematic diagram of the first conductive connector and the conductive component at the contact position in a display device provided in an embodiment of this application. Based on other embodiments, Figure 19 In the display device shown, the conductive element 106 has a limiting groove 126 on the side surface facing the circuit board 105. The limiting groove 126 is used to accommodate the end of the first conductive connector 107 that is away from the circuit board 105. In this way, the limiting groove 126 can limit the position of the end of the first conductive connector 107 that abuts against the conductive element 106, so as to prevent the end from shifting and improve stability.

[0119] Optionally, in order to improve the compatibility between the first conductive connector 107 and the conductive member 106, the abutting ends of the first conductive connector 107 and the conductive member 106 can be adapted to the shape of the limiting groove 126. If the limiting groove 126 is an arc-shaped groove, then the end is an arc-shaped protrusion that can seamlessly contact the arc-shaped groove. If the limiting groove 126 is a rectangular groove, then the end is a rectangular end that can seamlessly contact the rectangular groove.

[0120] In some embodiments of this application, the first conductive connector 107 is fixed to the circuit board 105 at one end, and abuts against the conductive element 106 at the other end. This results in a point-to-surface abutment between the upper end of the first conductive connector 107 and the conductive element 106, allowing any position on the lower surface of the conductive element 106 to abut against the upper end of the first conductive connector 107, reducing the alignment accuracy of the first conductive connector 107 at the abutment position during display assembly. The lower end of the first conductive connector 107 is fixed to the circuit board 105 at a point-to-point, allowing for pre-alignment of the lower end of the first conductive connector 107 with either the negative terminal N- or the positive terminal N+ of the circuit board 105, achieving accurate electrical connection fixation.

[0121] During the disassembly of the display module, it is necessary to clamp the related welded electrode structures, which is inefficient and unsafe. If a plug-in design is used to expose the related electrode structures, special design is required, and they need to be plugged / soldered together with the circuit board, which will affect subsequent disassembly and replacement. In this embodiment, by setting an electrical connection method in which at least one end of the conductive connector in the display device abuts against the opposite structural component, a safe and reliable electrical connection can be achieved at the abutment position based on the squeezing force after the display module 103 is installed. Furthermore, after the display module 103 is disassembled, the squeezing force at the abutment position is automatically released synchronously with the separation of the display module 103 from the support frame 100, thereby allowing the conductive connector to automatically and non-destructively separate at the abutment position.

[0122] In some embodiments of this application, at least one of the first conductive connector 107 to the fifth conductive connector 124 includes a compressible portion. For a conductive connector with a compressible portion, after the display module 103 is bonded and fixed to the support frame 100 based on the electro-adhesive layer 104, the compressible portion can be compressed based on the pressure exerted after the display module 103 is bonded and fixed, thereby enabling a safe and reliable electrical connection at the contact position. When the display module 103 is disassembled, the compressed compressible portion can be released as the display module 103 separates, achieving non-destructive separation at the contact position.

[0123] Optionally, at least one of the first conductive connector 107 to the fifth conductive connector 124 can be any one of a retractable probe, conductive foam, conductive cloth, conductive spring, and conductive spring, so that the conductive connector has a compressible portion. The conductive connector with the compressible portion can abut against the opposite structural component to achieve a flexible connection without welding. Compared with the welding fixation scheme, after disassembling the display module 103, it can achieve non-destructive automatic separation at the abutment position. With the relevant circuit path design, it can realize the function of rapid disassembly of the structural components in the display device, without additional clamping / plugging actions or disassembling the circuit board, etc., to achieve rapid and non-destructive disassembly of the relevant circuit connection structure.

[0124] In some embodiments, if at least one of the first conductive connector 107 to the fifth conductive connector 124 has a compressible portion, the height compression range of the compressible conductive connection is 0.5 mm to 1 mm. This height compression range is moderate, which on the one hand avoids the problem of poor electrical contact due to weak contact force caused by insufficient compression height, and on the other hand avoids the problem of inconvenient installation and instability between structural components due to excessive compression height.

[0125] The embodiments of this application are based on the abutment electrical connection design between the conductive connector and the opposite structural component, which can realize a soft connection at the abutment position, thereby enabling non-destructive separation at the abutment position and facilitating the disassembly of the structural component.

[0126] In conventional solutions that use electro-adhesive layers to make display modules detachable, exposed electrode structures are generally required for power supply. In the technical solution of this application, no exposed electrodes are required. The circuit board can be connected to the power supply based on the power supply structure of the display device, and the positive terminal N+ and the negative terminal N- provide a set voltage for the electro-adhesive layer 104.

[0127] Optionally, the display device can display virtual touch buttons to trigger a disassembly command. Based on the disassembly command, the circuit board 105 can provide a set voltage to the electro-adhesive layer 104 corresponding to the corresponding display module 103 to disassemble the corresponding display module 103, or the display device can have mechanical buttons to trigger the disassembly command. When there are multiple display modules 103, a set voltage can be provided independently to the frame or conductive plate 110 corresponding to the display module 103 to be disassembled, thereby realizing independent disassembly control of each display module 103.

[0128] Based on the display device provided in the above embodiments, another embodiment of this application also provides an electronic device, such as... Figure 20 As shown.
