LIGHT SOURCE MODULE, RELATED LIGHT BAR AND RELATED LIQUID CRYSTAL DISPLAY
First Claim
1. A light source module, comprising:
- a first PCB;
a plurality of LED chips, located on a top surface of the first PCB and electrically connecting with the first PCB, each of the plurality of LED chips comprising;
a light-emitting structure; and
at least a patterned reflective layer, located on the light-emitting structure, wherein the patterned reflective layer comprises at least an opening and a reflective region, the opening occupies at most 20% of the area of the patterned reflective layer; and
an sealant, covering the plurality of LED chips, wherein a top surface of the sealant forms a main surface of light extraction of the light source module.

Abstract
A light source module includes a bottom circuit board, a plurality of LED chips disposed on the bottom circuit board, and a sealant covering the LED chips. Each LED chip includes a light-emitting structure and at least a patterned reflecting layer disposed on the light-emitting structure. The patterned reflecting layer can appropriately enhance the brightness of the lateral surface of the LED chip. Thus, the diffuser particles included in the sealant can diffuse light so that the light beams emitted from the lateral surfaces of the LED chips can exit from the light-exiting surface of the light source module. Accordingly, a uniform light distribution of the light source module can be provided.
