Abstract

This invention relates to a liquid crystal display module with improved assembly strength, comprising a liquid crystal module, a backlight module, a lower protective frame, and a functional film. The backlight module is disposed on the rear side of the liquid crystal module, and the lower protective frame covers the liquid crystal module and its sides. This invention increases the bonding area of ​​the functional film, allowing the functional film to simultaneously bond to the top surfaces of both the liquid crystal module and the backlight module, thereby improving the robustness of the assembly of the backlight module and the liquid crystal module and preventing module separation.

Claims

1. A liquid crystal display module with improved assembly strength, comprising: a liquid crystal module, including: an upper substrate and a lower substrate bonded together, with a liquid crystal layer sealed between the upper substrate and the lower substrate; an upper polarizer bonded to an upper surface of the upper substrate; a lower polarizer bonded to a lower surface of the lower substrate; a backlight module disposed on the rear side of the liquid crystal module; a lower protective frame covering the rear side of the backlight module, the side edge of the backlight module, and the side edge of the liquid crystal module; a functional film, the area of ​​the functional film being larger than the area of ​​the upper polarizer, and the functional film together completely bonded to the upper polarizer and a top surface of the backlight module.

2. The liquid crystal display module with improved assembly strength as described in claim 1, wherein, An adhesive tape is attached to the periphery of the surface of the functional membrane, and the adhesive tape extends to the top surface of the lower protective frame, the outer side surface of the lower protective frame, and the bottom surface of the lower protective frame.

3. A liquid crystal display module with improved assembly strength as described in claim 1 or 2, wherein, The upper polarizer is flush with the top surface of the backlight module.

4. The liquid crystal display module with improved assembly strength as described in claim 3, wherein, This functional film is a super retardation film (SRF).

5. The liquid crystal display module with improved assembly strength as described in claim 4, wherein, The edge of the functional film covers the periphery of the top surface of the backlight module.

6. The liquid crystal display module with improved assembly strength as described in claim 1, wherein, The lower protective frame is a metal frame.
