LED(Light-Emitting diode)has series of advantages such as high illumination efficiency, full color, energy conservation, long service life, quick response speed, small size, solid light source, cold light source(without heat),friendly to environment, easily motivated, etc; which can be widely used in display of various signals and graphics.
Recently, quantities of breakthrough and progress of LED have been achieved on GaN-based materials, i.e. high efficiency blue and white LED has been made out not only to realize large-screen full color display, but also to replace the incandescent lamp and fluorescent lamp, thus can totally change our lives.
All color FPD: LCD backlight, LED monitor.
High-power LED, Mirco-LED, GaN red light LED and white light LED
