Title:
BACKLIGHT MODULE LIGHT SOURCE COMPONENT
Document Type and Number:
WIPO Patent Application WO/2020/108543
Kind Code:
A1
Abstract:
A backlight module light source component, comprising a PCB (10) and an LED (40) provided on the PCB (10). The surface of the PCB (10) provided with the LED light source is provided with a white solder mask layer (20), and a yellow phosphor ink coating unit (30) which diffuses outwards with the LED (40) as the center is provided on the white solder mask layer (20). According to the backlight module light source component, a yellow phosphor ink coating is provided on the surface of the PCB (10) where the backlight LED (40) is located, the yellow phosphor ink coating achieves reflection, refraction, or diffuse reflection of the LED light source, and optimum reflection, refraction, or diffuse reflection of light from the LED light source are achieved by optimizing the design of the area ratio of the phosphor ink to the white solder mask layer (20) on the PCB (10), thereby effectively alleviating the problem of uneven color rendering and uneven brightness directly above the backlight LED (40).
