Abstract

The invention provides a backlight module comprising a frame, an optical film group and a fixed ring; the optical film group is arranged in the frame, so the optical film group is surrounded by the frame or matched with the frame; the optical film group comprises lug directly or indirectly supported by a support face of the frame; the support face supports the lug, so the frame can support the optical film group; two sides of the lug are respectively provided with at least one groove; the fixed ring hoops the lug, and at least part of the fixed ring is clamped in the groove.

Description

[0001] 【Technical field】 [0002] The present invention relates to a backlight module for a display device; specifically, the present invention relates to a backlight module with an optical film positioning mechanism for a display device. [0003] 【Background technique】 [0004] figure 1 Shown is a traditional backlight module structure, including a plastic frame 10 and an optical film 30 . The main function of the optical film 30 is to adjust the optical behavior of light generated by the light source below, and the plastic frame 10 is used to carry the optical film 30 or support the upper display panel. The side of the plastic frame 10 is usually provided with a retaining wall, and the optical film 30 is disposed in the retaining wall and supported by the plastic frame 10 . In order to fix the relationship between the optical film 30 and the plastic frame 10, usually an adhesive tape 50 is attached to the side of the optical film 30 and the plastic frame 10, or between the ...
