Abstract

The invention relates to a flexible circuit board, a liquid crystal display module and a terminal. The flexible circuit board comprises a main body, a first branch and a second branch, wherein the first branch and the second branch are connected to the main body; the first branch and the second branch are spaced away from each other; a backlight is connected to the main body; the first branch can be bent with respect to the main body; one end, which is far away from the main body, of the first branch is connected with a key light; the second branch can be bent with respect to the main body; one end, which is far away from the main body, of the second branch is used for welding a motherboard. The flexible circuit board can be connected with the key light and the backlight, so that the motherboard of the terminal can provide an electrical signal to the backlight and the key light at the same time through the flexible circuit board. The flexible circuit board is simple in structure, occupies small space, and is lower in the production cost.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a flexible circuit board, a liquid crystal display module and a terminal. Background technique [0002] At present, the button structure of the liquid crystal display module of the mobile phone is realized by the button lamp and the flexible circuit board electrically connected to the button lamp. Specifically, the button lamp is located on the button flexible circuit board, and the button flexible circuit board is bonded to the touch screen through double-sided adhesive On the top, the button flexible circuit board is connected with the main board of the mobile phone through the button pad or the button insertion gold finger. The main board controls the key light to emit light through the key flexible circuit board, and the light of the key light evenly penetrates the key on the touch screen through the light guide plate, and then the front of the liquid crystal display modul...
