AU Optronics (AUO) plans on basing its OLED development using a-Si technology, and the company estimates it will enter into mass production in 2011.

CT Liu, vice-president and general manager of consumer product display business group of AUO indicated that AUO is going to start developing OLED again in the fourth quarter of this year and concentrate on commercializing small-sized panels.

Liu mentioned that OLED panels have a higher contract ratio, lower power consumption and are much thinner compared to the thin film transistor (TFT) LCD panels. And as OLED technology matured, costs will drop below than of TFT. AUO will also focus its development on efficient OLED manufacturing processes. Liu explained that a-Si technology is more suited for OLED panel making because a-Si has better yield rates and more stable circuits compare to LTPS technology.
