Abstract

The invention discloses a backlight module and a liquid-crystal display device. The backlight module comprises a backlight flexible printed circuit board and a faceplate flexible printed circuit board, wherein the backlight flexible printed circuit board comprises at least one positioning hole, and the faceplate flexible printed circuit board comprises at least one positioning protrusion matched with the positioning holes. Alignment efficiency and accuracy of the backlight flexible printed circuit board and the faceplate flexible printed circuit can be improved, and welding after alignment is more stable. Furthermore, the positioning protrusions are made of conductive materials and are grounded via positioning welding pads therebelow, and electrostatic protection can be realized.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to the technical field of module structure, and in particular to a backlight module and a liquid crystal display device.
