Abstract

A narrow bezel liquid crystal display module including a backlight module and a liquid crystal panel disposed opposite to each other. The backlight module and the liquid crystal panel adhering to each other via a double-sided adhesive. The backlight module including a back frame and an optical assembly disposed in the back frame, wherein at least a part of the double-sided adhesive adopts a first type of double-sided adhesives, the first type of double-sided adhesives includes a light shielding part and a light transmission part extending along its length direction, the light shielding part adheres to a side wall of the back frame, and the light transmission part adheres to the optical assembly. The light transmission part of the double-sided adhesive may have a greater width to extend to the optical assembly, thereby increasing a width of the double-sided adhesive overall.

Claims

1. A narrow bezel liquid crystal display module, comprising a backlight module and a liquid crystal panel disposed opposite to each other, the backlight module and the liquid crystal panel adhering to each other via a double-sided adhesive, the backlight module comprising a back frame and an optical assembly disposed in the back frame, wherein at least a part of the double-sided adhesive adopts a first type of double-sided adhesives, the first type of double-sided adhesives comprises a light shielding part and a light transmission part extending along its length direction, the light shielding part adheres to a side wall of the back frame, and the light transmission part adheres to the optical assembly.

2. The narrow bezel liquid crystal display module of claim 1, wherein the light transmission part of the first type of double-sided adhesives is manufactured by a light transmission material, and the light shielding part thereof is manufactured by painting a black material.

3.
