Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal displays, in particular to a liquid crystal display module structure that is easy to assemble. Background Art

[0002] A liquid crystal display module usually consists of an LCD module and a backlight module. In production and assembly, the LCD module and the backlight module are assembled together. For the convenience of assembly, in the existing liquid crystal display module, a limiting structure in the shape of an armrest is provided in the backlight rubber frame of the backlight module, and the LCD is wrapped during assembly. The border of the liquid crystal display module with this structure is relatively wide. With the development of technology, it can no longer meet the narrow border requirements of consumers for liquid crystal displays.
