Description

technical field

[0001] The invention relates to a light source device for a backlight module of a liquid crystal display. Background technique

[0002] Liquid Crystal Displays (LCDs) are widely used in various electronic products such as computers, televisions, and mobile phones. A backlight module is one of the important components of a liquid crystal display. The light source device used in the backlight module directly affects the performance and assembly cost of the backlight module. Among them, light emitting diodes (Light Emitting Diodes, LEDs) have become one of the light sources used in liquid crystal displays due to their small size and low energy consumption. In addition, compared with the direct-type backlight module, the edge-type backlight module has attracted attention because it can have a thinner thickness.

[0003] A common structure of an edge-lit backlight module includes a light source device, a light guide plate, a reflector plate, and a diaphragm. W...
