RITEK manufactured the first OLED in Taiwan. RITEK also established the first fully automation mass production line in the world.
Differing from liquid-crystal displays(LCDs), OLEDs are self-emitting and do not require backlight. It can be extremely thin and lightweight which eliminate the needs for bulky mercury lamps.
The SMOLED/PLED is analogous to that of conventional light-emitting diodes in terms of the working principle. The light emission is through the recombination of electrons and holes from the cathode and anode, respectively.

In year 2000, RiTdisplay was spun off from RiTEK Corporation Flat Panel Display Division. RiTdisplay Corporation has further extended RiTEK's core technology and effective management into itself. Furthermore, many internationally renowned companies including Intel, DuPont, GE, Futaba, etc. were strategic alliances with RiTdisplay Corporation.
