Abstract

The invention relates to a flexible circuit board used for connecting a display panel, and the flexible circuit board comprises a substrate which comprises a main body area; one end of the main body area is provided with a first binding area, and the first binding area is provided with a bonding pad; a transition area is arranged between the first binding area and the main body area, the transition area is provided with a transition structure, the bonding pad and the transition structure are both located on the first surface of the base material, and the bonding pad is located on the second surface of the base material. The thickness of the transition structure in the direction perpendicular to the base material is less than the thickness of the bonding pad in the direction perpendicular to the base material. The invention further relates to a display module.

Description

technical field [0001] The invention relates to the technical field of display product production, in particular to a flexible circuit board and a display module. Background technique [0002] With the continuous development of AMOLED (Active Matrix / Organic Light Emitting Diode), flexible display and full-screen display will definitely be the development trend in the next few years, but the development of new technologies will inevitably bring new technical challenges. Folding mobile phones, folding notebooks, as folding products become bigger and bigger, the problems they encounter are unprecedented. As the size of folding products increases, the resolution will also increase. Bonding of multiple FPCs or COF (chip-on-film) is bound to be a trend, but as the bonding area increases, the short-circuit of the bonding area Risks have also risen exponentially. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a f...
