A brand new design concept is proposed in this paper. In order to increase the efficiency of light emission, we develop a new scheme in modulating the light rays with white LED light sources emitting from the angle side and in improving design of light guide plate in the backlight module. Results of simulation are. shown. The new scheme does not require the usual tedious procedures in adjusting the dot patterns on conventional backlight module design processes, As compared with the current method, the novel design provides much better performance in brightness, increasing emission efficiency from 53% up to 74%.
