Abstract
Description
Technical Field
[0001] This utility model relates to display modules, and more particularly to a display module with a two-in-one FPC. Background Technology
[0002] Currently, integrated modules include display and touch functions. Some LCDs are designed with the touch circuitry on the surface of the color filter (CF) (the side closest to the upper polarizer), while the display circuitry is on the TFT surface (the side closest to the CF). This necessitates two bonding processes during module production (bonding the main (display) FPC and the touch FPC). Then, one end of the touch FPC is soldered to the main FPC to establish electrical connections. Insulating tape is also applied to the soldering points to insulate the pads from external sources. This structure involves numerous processes and is costly.
[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a display module with a two-in-one FPC.
[0005] The technical solution of this utility model is as follows: This utility model provides a display module with a two-in-one FPC, including: a display glass assembly and a module FPC. The CF surface of the display glass assembly is provided with a touch bonding area, and the TFT surface of the display glass assembly is provided with a display bonding area. The module FPC includes a touch bonding connector and a display bonding connector, and an elongated slot is provided between the touch bonding connector and the display bonding connector.
[0006] Furthermore, the depth of the elongated slot extending into the main body area of the module FPC is greater than or equal to half the width of the main body area of the module FPC.
[0007] The advantages of this utility model by adopting the above solution are as follows: By integrating the display bonding connector and the touch bonding connector on the module FPC, a module FPC can be bonded to the display bonding area and the touch bonding area of the display glass assembly at the same time, which can reduce the welding process and the process of applying insulating adhesive, and save insulating adhesive material; and the three materials (insulating adhesive, touch FPC, and main FPC) are combined into one material, reducing management costs. Attached Figure Description
[0008] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation
[0009] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0010] Please see Figure 1 This utility model provides a display module with a two-in-one FPC, including: a display glass assembly 1 and a module FPC 4. The CF surface of the display glass assembly 1 is provided with a touch bonding area 2, and the TFT surface of the display glass assembly 1 is provided with a display bonding area 3. The module FPC 4 includes a touch bonding connector 5 and a display bonding connector 6. The touch bonding connector 5 is bonded to the touch bonding area 2, and the display bonding connector 6 is bonded to the display bonding area 3. The module FPC 4 is provided with an elongated slot 7 between the touch bonding connector 5 and the display bonding connector 6. The elongated slot 7 ensures the relative independence between the touch bonding connector 5 and the display bonding connector 6. Therefore, during the bonding process of bonding the touch bonding connector 5 and the display bonding connector 6 separately, due to the presence of the elongated slot 7, the touch bonding connector 5 and the display bonding connector 6 are less likely to affect each other during the bonding process, and are less likely to affect the bonding process due to deformation of the module FPC 4 caused by bonding.
[0011] Furthermore, the elongated slot 7 extends into the main body area of the module FPC 4 to a depth greater than or equal to half the width of the main body area of the module FPC 4, which can effectively ensure that the elongated slot 7 achieves its function.
[0012] In summary, the beneficial effects of this solution are as follows: integrating display bonding connectors and touch bonding connectors on the module FPC allows a single module FPC to be bonded to both the display bonding area and the touch bonding area of the display glass assembly simultaneously, reducing the need for soldering and applying insulating adhesive, thus saving insulating adhesive materials; furthermore, combining the three materials (insulating adhesive, touch FPC, and main FPC) into one material reduces management costs.
[0013] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
