Problems solved by technology

[0004] However, with the development of display technology, flexible or curved products have appeared in the display module. When the FPC is arranged in the above-mentioned parallel in-line method, when the display module is forced to form a curved surface, the FPC will also bend accordingly. The uneven force on each binding position of the FPC causes the FPC to fall off; or the FPC is torn and damaged during the bending process
Moreover, in the FPC binding of the display module, multiple FPCs will be used. Since the appearance of the FPCs is similar, it is difficult to distinguish them during replacement or use, which will cause the risk of misuse

Abstract

The invention discloses a display module which comprises a display panel and a peripheral circuit. One or a plurality of FPCs is bound and conducted with the display panel and the peripheral circuit, one FPC is obliquely arranged, at least one of the FPCs is obliquely arranged, and the oblique FPC is not perpendicular to the display panel. The number of FPCs can be one or more, and at least one FPC is obliquely arranged, so that the tension of the FPCs can be increased. When the display module is designed into a curve shape or is a flexible display device, the FPCs are difficult to separate or tear. When the number of FPCs is more, after the FPC is obliquely arranged, each FPC can be easily distinguished, and material misuse possibility is reduced.

Description

technical field [0001] The present invention relates to a display device, in particular to a display module based on FPC binding. Background technique [0002] Because a flexible printed circuit board (FPC) has the advantages of high wiring density, light weight, and thin thickness, the FPC is widely used in the manufacture of various display modules. In the display module, FPC plays the role of connecting the internal circuit of the display panel with peripheral circuits such as printed circuit board (Printed Circuit Board, PCB) and drive integrated circuit (Integrated Circuit, IC). In the aforementioned connection, heating and pressure are usually used. The way to achieve stable and reliable mechanical and electrical connections, these connections are collectively referred to as flexible circuit board bonding (FPC Bonding). [0003] In the FPC binding technology of the display module, a layer of anisotropic conductive film (Anisotropic Conductive Film, ACF) is usually cov...
