Paper Abstract

The paper proposes a newly developed light source module mixing R.G.B. LED (Red, Green, Blue, Light Emitting Diode) for a modern LED backlight system, which might replace the white light LED and traditional CCFL (Cold Cathode Fluorescent Lamp). This system consists of three parts, a newly designed symmetric mirror for complete color mixing, a R.G. B LED (Red, Green, Blue Light Emitting Diode) light source and a diffusion plate with a newly designed microstructure for the improvement of light uniformity. The light module is designed and simulated by an ASAP (Advanced Systems Analysis Program), in which a sample with 160mm×90mm( around 7-inch panel) is presented with sixteen LEDs light source. Good color saturation and excellent light uniformity are reached in this research.
