[0044] This application provides a display module and a mobile terminal. These will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.
[0045] Please combine Figure 1 , Figure 2 and Figure 3 ;in, Figure 1 This is a schematic diagram of the structure of the display module provided in the embodiments of this application; Figure 2 This is a first top-view cross-sectional schematic diagram of the display module provided in the embodiments of this application; Figure 3 This is a second top-view cross-sectional schematic diagram of the display module provided in the embodiments of this application.
[0046] It should be noted that, Figure 2 This is a top view cross-sectional view of the display module in the second direction Y1. Figure 3 The diagram shows a top view cross-section of the display module 1 in the third direction Y2; wherein the second direction Y1 is opposite to the third direction Y2, the second direction Y1 is the direction from which the display panel 40 points to the carrier substrate 10, and the third direction Y2 is the direction from which the carrier substrate 10 points to the display panel 40.
[0047] This embodiment provides a display module 1, which includes a carrier substrate 10, a limiting layer 20, a connecting layer 30, and a display panel 40 stacked together. The limiting layer 20 is disposed on one side of the carrier substrate 10 and has multiple mounting slots 21. The display panel 40 is disposed on the side of the limiting layer 20 away from the carrier substrate 10 and includes multiple sub-display panels 41 arranged in an array. The connecting layer 30 is disposed on the side of the sub-display panels 41 close to the carrier substrate 10 and includes multiple connectors 31 spaced apart. The first end of each connector 31 is connected to the sub-display panel 41, and the second end of each connector 31 is connected to the carrier substrate 10 and is disposed within the mounting slots 21.
[0048] The adhesive force between the connector 31 and the limiting layer 20 is less than the adhesive force between the connector 31 and the supporting substrate 10.
[0049] It should be noted that in traditional splicing screens, multiple display panels are located on the same substrate. Due to the large number of display panels, daily maintenance is inconvenient. Usually, the entire splicing screen needs to be disassembled, which makes it impossible to accurately and conveniently inspect the fault location. It also increases the risk of damaging surrounding display panels and the high cost of repair.
[0050] Specifically, in this embodiment, when installing or replacing the sub-display panel of the display module, the connector of the sub-display panel can be placed into the mounting groove first, and the connector is not in contact with the carrier substrate. It is understood that since the adhesive force between the connector and the limiting layer is less than the adhesive force between the connector and the carrier substrate, the sub-display panel can be positioned and moved horizontally on the carrier substrate. After confirming the position of the sub-display panel, the connector is pressed on the carrier substrate, thereby bonding the sub-display panel to the carrier substrate through the connector, which helps to improve the installation or replacement efficiency of the display module.
[0051] In one embodiment, the material of the connecting layer 30 is a shape memory polymer, which includes, but is not limited to, at least one of thermotropic shape memory polymers, chemically induced shape memory polymers, electrotropic shape memory polymers, and photocurable shape memory polymers.
[0052] It is understood that in this embodiment, by setting the material of the connecting layer 30 to a shape memory polymer, and utilizing the reversible deformation characteristic of the shape memory polymer under deformation environment, the environmental parameters of the connector 31 on the faulty light-emitting unit are changed, thereby reducing the adhesion between the connector 31 and the carrier substrate 10. This allows the faulty light-emitting unit to be removed from the carrier substrate 10. Then, the connector 31 on the new sub-display panel 41 is placed into the corresponding mounting slot 21, and the environmental parameters of the connector 31 on the new light-emitting unit are changed, allowing the connector 31 to connect with the carrier substrate 10. This achieves the repair of the display module 1. This embodiment reduces the repair difficulty and repair cost of the display module 1.
[0053] Specifically, the material of the connecting layer 30 is a thermotropic shape memory polymer. When the connector 31 is heated, the adhesive force between the connector 31 and the sub-display panel 41 is greater than the adhesive force between the connector 31 and the carrier substrate 10. Therefore, when repairing the display module, after determining the location of the faulty sub-display panel, the connector on the faulty sub-display panel is selectively heated from the side of the carrier substrate away from the faulty sub-display panel. This reduces the adhesion between the connector on the faulty sub-display panel and the carrier substrate, thereby removing the faulty sub-display panel from the carrier substrate. Then, the connector on the new sub-display panel is placed into the corresponding mounting slot, thus achieving the repair of the display module and reducing the repair difficulty and cost of the display module.
[0054] Optionally, the thermotropic shape memory polymer includes, but is not limited to, at least one of cross-linked polyolefin shape memory polymer or polyurethane shape memory polymer; it is understood that this embodiment utilizes the characteristic of shape memory polymers to have reversible deformation under deformation environment, thereby reducing the repair difficulty of the sub-display panel 41 in the display module 1 and thus reducing the repair cost of the display module 1.
[0055] For example, when repairing the display module 1, after determining the location of the faulty sub-display panel 41, the connector 31 on the faulty sub-display panel 41 is heated from the side of the carrier substrate 10 away from the faulty sub-display panel 41. When the connector 31 is heated to a first preset temperature, the connector 31 on the faulty sub-display panel 41 changes from a first state to a second state, thereby reducing the adhesion between the connector 31 on the faulty sub-display panel 41 and the carrier substrate 10, while the adhesion of the unheated connector 31 remains unchanged. Thus, the faulty sub-display panel 41 located on the carrier substrate 10 can be easily removed using an adsorption tool (e.g., a suction cup).
[0056] Following the above, the connector 31 on the new (fault-free) sub-display panel 41 is then placed into the corresponding mounting slot 21 (at this time, the connector 31 is in the third state). From the side of the carrier substrate 10 away from the new sub-display panel 41, the connector 31 on the new sub-display panel 41 is heated. When the connector 31 is heated to the first preset temperature, the connector 31 on the new sub-display panel 41 changes from the third state to the first state, thereby increasing the adhesion between the connector 31 on the new sub-display panel 41 and the carrier substrate 10. This allows the sub-display panel 41 to be bonded to the carrier substrate 10 through the connector 31, thus achieving the repair of the display module 1 and reducing the repair difficulty and cost of the display module 1.
[0057] It should be noted that the first state can be a state in which the connector 31 is viscous, the second state can be a state in which the viscosity is low or non-viscous, the third state can be a state in which the connector 31 is solid or in a state in which the viscosity is low, and the first preset temperature is the transition temperature of the thermotropic shape memory polymer. The first preset temperature can be selected according to different materials. In this embodiment, the technical solution of this application is illustrated by taking the first preset temperature as greater than 80 degrees Celsius or the first preset temperature as greater than 200 degrees Celsius.
[0058] In one embodiment, the material of the connecting layer 30 is a heat-degradable adhesive; wherein, the heat-degradable adhesive will have its properties greatly reduced after being heated to a certain extent; optionally, the heat-degradable adhesive includes, but is not limited to, one of epoxy adhesive, silicone or polyacrylic adhesive; preferably, an expanding foam or other initiator may be added to the heat-degradable adhesive, and when the connector 31 is heated to a second preset temperature, the expanding foam expands, thereby reducing the stickiness of the heat-degradable adhesive, thereby making the second connecting layer 30 easy to peel off; wherein, the second preset temperature is 80 degrees Celsius to 200 degrees Celsius.
[0059] It is understood that this embodiment uses a heat-loss adhesive for the connecting layer 30. This utilizes the characteristic that the adhesiveness of the heat-loss adhesive decreases significantly after heating to a certain extent, thus facilitating the peeling of the second connecting layer 30 from the carrier substrate 10. This reduces the difficulty of repairing the sub-display panel 41 in the display module 1, thereby reducing the repair cost of the display module 1. For example, when repairing the display module 1, after determining the location of the faulty sub-display panel 41, the faulty sub-display panel 41 is repaired from the side of the carrier substrate 10 away from the faulty sub-display panel 41. The connector 31 on the display panel 41 is heated. When the connector 31 is heated to a second preset temperature, the adhesion between the connector 31 on the faulty sub-display panel 41 and the carrier substrate 10 decreases, while the adhesion of the unheated connector 31 remains unchanged. Thus, the faulty sub-display panel 41 located on the carrier substrate 10 can be easily removed using an adsorption tool, and the connector 31 on the new sub-display panel 41 can be placed into the corresponding mounting slot 21, thereby achieving the repair of the display module 1 and reducing the repair difficulty and cost of the display module 1.
[0060] It should be noted that after the connector 31 on the new sub-display panel 41 is placed into the corresponding mounting slot 21, the connector 31 on the new sub-display panel 41 can be heated at a low temperature from the side of the carrier substrate 10 away from the new sub-display panel 41, thereby making the connector 31 fluid, thereby enhancing the adhesion between the connector 31 and the carrier substrate 10, and improving the firmness and reliability of the connection between the connector 31 and the carrier substrate 10.
[0061] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 4 ;in, Figure 4 This is a cross-sectional schematic diagram of the sub-display panel provided in an embodiment of this application.
[0062] In one embodiment, the sub-display panel 41 includes a driving substrate 411 and a light-emitting unit 412 disposed on the driving substrate 411. The driving substrate 411 includes a driving circuit 411A and a pad 411B. The driving circuit 411A and the pad 411B are electrically connected. The pad 411B is located on the surface of the driving substrate 411. The light-emitting unit 412 includes a solder foot 412A and a light-emitting element 412B connected to each other. The solder foot 412A is located on the side of the light-emitting element 412B close to the pad 411B. The solder foot 412A is electrically connected to the pad 411B.
[0063] The surface of the driving substrate 411 is the side of the pad 411B away from the driving circuit 411A. The driving circuit 411A is used to provide driving electrical signals to the sub-display panel 41. The sub-display panel 41 includes, but is not limited to, micro-light-emitting diodes (Micro-LEDs).
[0064] It should be noted that this embodiment does not impose specific limitations on the number or arrangement of the sub-display panels 41. That is, in this embodiment, the display panel 40 may include one sub-display panel 41 or the display panel 40 may include multiple sub-display panels 41. In this embodiment, the technical solution of this application is illustrated by taking the display panel 40 as having 3x3 sub-display panels 41 as an example.
[0065] Please combine Figure 1 , Figure 2 , Figure 3 and Figure 5 and Figure 6 ;in, Figure 5 for Figure 1 A schematic diagram of the first cross-section at A-Aˋ; Figure 6 for Figure 3 A schematic diagram of the cross-section at point B-Bˋ.
[0066] In one embodiment, the limiting layer 20 includes a plurality of spaced limiting members 22, and the mounting groove 21 is disposed between adjacent limiting members 22; a connector 31, a sub-display panel 41 and a mounting groove 21 are correspondingly disposed; wherein, a connector 31 includes a plurality of spaced connecting sub-members 311, and the plurality of connecting sub-members 311 are disposed within a mounting groove 21.
[0067] It should be noted that this embodiment uses the example of a connector 31 including three connector sub-components 311 to illustrate the technical solution of this application. This embodiment does not impose a specific limitation on the number of connector sub-components 311 included in the connector sub-component 31.
[0068] It is understood that, by setting the connector 31, the sub-display panel 41, and the mounting slot 21 in a corresponding manner, the sub-display panel 41 can be accurately positioned when it is replaced, which is beneficial to improving the repair efficiency of the display module 1. By setting the connector 31 to include multiple spaced connecting sub-components 311, and the multiple connecting sub-components 311 being disposed in the mounting slot 21, the stability of the connection between the sub-display panel 41 and the carrier substrate 10 is improved.
[0069] Furthermore, in the direction perpendicular to the carrier substrate 10, the width of the connector 31 is smaller than the width of the mounting groove 21, and the bonding force between the connector sub-part 311 near the limiting member 22 and the limiting member 22 is smaller than the bonding force between the limiting member 22 and the carrier substrate 10. This makes it quicker and more convenient to replace the sub-display panel 41, and less likely to affect the surrounding sub-display panels 41, thereby improving the repair efficiency of the display module 1 and reducing the repair cost of the display module 1.
[0070] Furthermore, since the adhesive force between the connecting sub-component 311 of the limiting member 22 and the limiting member 22 is less than the adhesive force between the limiting member 22 and the supporting substrate 10, it is easier to align and adjust the sub-display panel 41 in the first direction X when installing the sub-display panel 41, which is beneficial to improving the repair efficiency of the display module 1.
[0071] In one embodiment, there is no adhesive contact between the connecting sub-component 311 and the limiting member 22, thereby further improving the repair efficiency of the display module 1 and reducing the repair cost of the display module 1.
[0072] Furthermore, a hydrophobic film 50 is provided between the limiting member 22 and the connecting member 31. The hydrophobic film 50 is attached to the surface of the limiting member 22 away from the supporting substrate 10, thereby making the surface of the limiting member 22 hydrophobic.
[0073] Specifically, the hydrophobic membrane 50 includes a plurality of hydrophobic portions 51, each hydrophobic portion 51 being disposed corresponding to a limiting member 22, and the hydrophobic portion 51 being located at least on the side of the limiting member 22 near the connector 31.
[0074] Optionally, the material of the hydrophobic film 50 includes, but is not limited to, fluorine- or silicon-containing polymer materials. Preferably, the material of the hydrophobic film 50 is fluorinated silane. It can be understood that, in this embodiment, by setting the hydrophobic film 50 to be attached to the surface of the limiting member 22 away from the carrier substrate 10, when the connector 31 contacts the limiting member 22, the two do not stick to each other, thereby achieving non-adhesive contact between the connector 31 and the limiting member 22. This makes it faster and more convenient to replace the sub-display panel 41 of the display module 1, improves the repair efficiency of the display module 1, and reduces the repair cost of the display module 1.
[0075] For further information, please refer to [link / reference]. Figure 5 and Figure 6In one embodiment, in a direction perpendicular to the carrier substrate 10, the connecting sub-component 311 includes a first surface 311A and a second surface 311B disposed opposite to each other. The first surface 311A is connected to the carrier substrate 10, and the second surface 311B is connected to the sub-display panel 41.
[0076] It is understood that, in this embodiment, the connecting component 311 includes a first surface 311A and a second surface 311B disposed opposite to each other. The first surface 311A is connected to the carrier substrate 10, and the second surface 311B is connected to the sub-display panel 41. Therefore, when the connecting component 31 is heated, the bonding force between the connecting component 31 and the sub-display panel 41 is greater than the bonding force between the connecting component 31 and the carrier substrate 10. This ensures that during the repair process of the display module 1, the connecting component 31 of the faulty sub-display panel 41 is separated from the carrier substrate 10, thereby improving the repair efficiency of the display module 1 and reducing the repair cost of the display module 1.
[0077] Furthermore, in one embodiment, the connecting sub-component 311 is shaped like a frustum, a truncated cone, or a prism; the limiting member 22 is shaped like a triangular prism, a cylinder, or a prism; and the mounting groove 21, when projected onto the support substrate 10, is shaped like a circle, a rhombus, a rectangle, or an ellipse.
[0078] Specifically, in the direction perpendicular to the support substrate 10, the shape of the cross-section of the connecting sub-component 311 includes, but is not limited to, an inverted trapezoid or a rectangle; preferably, the shape of the connecting sub-component 311 is a frustum, and in the direction perpendicular to the support substrate 10, the shape of the cross-section of the connecting sub-component 311 is an inverted trapezoid; the shape of the limiting member 22 is a triangular prism, and in the direction perpendicular to the support substrate 10, the shape of the cross-section of the limiting member 22 is a triangle; the shape of the mounting groove 21 projected onto the support substrate 10 is a rectangle.
[0079] Furthermore, please combine Figure 1 , Figure 7 and Figure 8 ;in, Figure 7 This is a third top-view cross-sectional schematic diagram of the display module provided in the embodiments of this application; Figure 8 for Figure 1 A schematic diagram of the second cross-section at A-Aˋ.
[0080] It should be noted that, Figure 7 This is a top view cross-sectional view of the display module 1 in the second direction Y1.
[0081] In one embodiment, the limiting layer 20 includes a plurality of spaced-apart limiting members 22, and the mounting groove 21 is disposed between adjacent limiting members 22; a connector 31 includes a plurality of spaced-apart connecting sub-members 311, a connecting sub-member 311 is disposed in a mounting groove 21, and the connecting sub-member 311 and the limiting member 22 are alternately arranged along a first direction X, the first direction X and the second direction Y1 form a preset angle, and this embodiment takes the preset angle as 90 degrees, that is, the first direction X and the second direction Y1 are perpendicular to the example to illustrate the technical solution of this application.
[0082] Specifically, the connecting sub-component 311 and the limiting member 22 are alternately arranged along the first direction X, and there is no adhesive contact between the limiting member 22 and the connecting sub-component 311. It can be understood that, in this embodiment, by setting the limiting layer 20 to include a plurality of spaced limiting members 22, and the connecting member 31 and the limiting member 22 are alternately arranged along the first direction X, the limiting layer 20 has high stability and better load-bearing capacity, thereby improving the stability of the connection between the display panel 40 and the supporting substrate 10. Furthermore, by setting one of the connecting sub-components 311 in a mounting groove 21, the sub-display panel 41 can be accurately positioned when it is replaced, which is beneficial to improving the repair efficiency of the display module 1.
[0083] Furthermore, please combine Figure 1 , Figure 9 and Figure 10 ;in, Figure 9 This is a fourth top-view cross-sectional schematic diagram of the display module provided in the embodiments of this application; Figure 10 This is a fifth top-view cross-sectional schematic diagram of the display module provided in the embodiments of this application.
[0084] It should be noted that, Figure 9 This is a top view cross-sectional view of the display module 1 in the second direction Y1. Figure 10 This is a top view cross-section of the display module in the third direction Y2.
[0085] In one embodiment, a plurality of mounting slots 21 are arranged in an array on the limiting layer 20, and the connector 31 includes a plurality of connector sub-components 311 arranged in an array; wherein, one connector sub-component 311 is provided corresponding to one mounting slot 21, and one connector sub-component 311 is disposed in one mounting slot 21 and is snapped into the mounting slot 21.
[0086] It is understood that in this embodiment, by setting the connecting sub-component 311 within the mounting groove 21 and engaging with the mounting groove 21, the sub-display panel 41 is engaged with the carrier substrate 10 via the connecting sub-component 311, thereby improving the stability of the connection between the display panel 40 and the carrier substrate 10. Furthermore, by setting one connecting sub-component 311 corresponding to one mounting groove 21, the positioning connection between the sub-display panel 41 and the carrier substrate 10 can be facilitated, making it faster and more convenient to replace the sub-display panel 41 in the display module 1, and less likely to affect the surrounding sub-display panels 41, thereby improving the repair efficiency of the display module 1, reducing the adjustment range during the repair of the display module 1, and thus reducing the repair cost of the display module 1.
[0087] Please combine Figure 1 , Figure 9 , Figure 10 and Figure 11 ;in, Figure 11 for Figure 9 A schematic diagram of the cross-section at C-Cˋ.
[0088] In one embodiment, the width of the connecting sub-component 311 is less than or equal to the width of the mounting groove 21, and the shape of the connecting sub-component 311 is one of a frustum, a frustum of a cylinder, or a prism; the shape of the limiting member 22 is one of a triangular prism, a cylinder, or a prism; and the shape of the mounting groove 21 projected onto the support substrate 10 is one of a circle, a rhombus, a rectangle, or an ellipse.
[0089] Specifically, in the direction perpendicular to the support substrate 10, the shape of the cross-section of the connecting sub-component 311 includes, but is not limited to, an inverted trapezoid or a rectangle; preferably, the shape of the connecting sub-component 311 is a cylinder, and the shape of the cross-section of the connecting sub-component 311 in the direction perpendicular to the support substrate 10 is rectangular; the shape of the limiting member 22 is a cylinder, and the shape of the cross-section of the limiting member 22 in the direction perpendicular to the support substrate 10 is rectangular; the shape of the mounting groove 21 projected onto the support substrate 10 is rectangular.
[0090] Furthermore, the hydrophobic film 50 is attached to the surface of the limiting member 22 away from the carrier substrate 10. The hydrophobic film 50 includes a plurality of hydrophobic portions 51, one of which is disposed corresponding to one of the limiting members 22, and the hydrophobic portions 51 are disposed around the limiting member 22, thereby making the surface of the limiting member 22 hydrophobic. When the connecting sub-component 311 contacts the limiting member 22, the two do not stick to each other, thereby achieving non-adhesive contact between the connecting sub-component 311 and the limiting member 22, further improving the efficiency of replacing the sub-display panel 41 of the display module 1, thereby reducing the repair cost of the display module 1.
