Abstract:
1. An LED backlight assembly comprising a plurality of light source modules arranged in a matrix comprising a plurality of colored LEDs, a light-diffusion plate disposed over the plurality of light source modules, wherein the light-diffusion plate diffuses light emitted from the plurality of light source modules; a frame holding the plurality of light source modules and the light-diffusion plate; a reflecting plate disposed on an inner surface of the frame, wherein a plurality of holes is formed at fixed intervals in the reflecting plate; wherein the light source modules are aligned with a plurality of rows and columns, each light source module being positioned at an intersection of each row and each column of the light source modules, wherein each light source module comprises sequentially arranged in the order of a red LED, a pair of neighboring green LEDs, a blue LED, and a red LED in a line; wherein the LEDs in the each light source module are exposed through the holes of the reflecting plate; wherein one or more of the plurality of light source modules is disposed on a metal-core printed circuit board; and wherein the light source modules are selectively controlled, thereby allowing luminance and color temperature to be controlled with simplicity and ease.
