(2) ACF (Anisotropic is formed between backlight FPC (i.e. the second flexible circuit board 110) and single layer function part Conductive film, i.e., different rectangular conducting resinl) as the one kind for conducting component;
(3) ITO conduction is formed between single layer function part and the welding section of main FPC (i.e. the first flexible circuit board 108) Film (i.e. indium tin oxide conductive film), and photoetching treatment is to form superfine wiring;
(4) use FOG bonding (Flexible on glass) technique by main FPC (i.e. the first flexible circuit board 108) Gland is to welding section.
To sum up, it is contemplated that the backlight FPC (i.e. the second flexible circuit board) proposed in the related technology is soldered to main FPC (i.e. One flexible circuit board) caused by many technical problems, the invention proposes a kind of new LCD assemblies and liquid crystal display to set It is standby, at least it is able to achieve following technical effect:
(1) reserved welding region is not needed on main FPC (i.e. the first flexible circuit board), reduces the surface area of FPC;
(2) backlight FPC (i.e. the second flexible circuit board) does not need to be bent to backlight with main FPC (i.e. the first flexible circuit board) The back side (i.e. lower surface) of mould group, therefore, when carrying out reliability test to complete machine, backlight FPC (i.e. the second flexible circuit board) Collision is not interfered with backlight module, a possibility that white group, white point and damage occurs in backlight FPC (i.e. the second flexible circuit board) It greatly reduces;
(3) welding disking area reduces the complexity and production cost of complete machine assembling without increasing shading rubber belt;
(4) by the way that the second flexible circuit board to be soldered directly to the upper surface of single layer function part, without being stacked at In one flexible circuit board, in conjunction with the small advantage of the thickness of single-glass technology, disclosure of the invention can be made to implement the liquid proposed Brilliant display module is further lightening.
