Frame structure used in a backlight module
View Patent ↗A frame structure used in a backlight module is disclosed. The frame structure includes an upper frame and a lower frame. By combining the T-shape hook of the upper frame and the corresponding groove of the lower frame, the components of the backlight module, such as the linear light source, the light source fixer, the light guide, the upper diffusing plate, the reflective plate, the lower diffusing plate, and the prism plate can be well assembled. Therefore, an improved positioning and fixing efficacy is provided.
1. A frame structure used in a backlight module comprising:
a lower frame for holding components of the backlight module; and
an upper frame mounted on the lower frame for assembling the components of the backlight module;
wherein the upper frame has at least one T shape hooking element, and restrains the movements of the components of the backlight module in both cross and upright directions simultaneously;
the lower frame has at least one corresponding engaging element that can engage with at least one T shape hooking element; the at least one engaging element corresponding to the T shape hook is a T shape groove;
and the movement of each T shape hooking element is limited by a longitudinal portion and at least a latitudinal portion of the engaging element when the hooking element is engaged.
2. The frame structure as claimed in claim 1 , wherein at least one T shaped hooking element is located at a periphery of the upper frame.
