Chi Mei EL Corporation (CMEL) announced that it has successfully employed the latest low temperature poly-silicon thin film transistor (LTPS TFT) process technology from Chi Mei Optoelectronics (CMO) together with its own organic light-emitting diodes (OLED) equipment and technology to develop a full-function, full-color 25" OLED TV panel.

This 25" OLED panel is currently the world's largest LTPS AMOLED panel. This successful application of new technologies from CMEL and CMO showcases CMEL's mature product development capabilities and advanced OLED process technology, as well as CMO's unique LTPS TFT process technology.

The new 25" AMOLED TV panel uses the latest LTPS TFT production technology developed by CMO to avoid non-uniform images that plague conventional LTPS TFT panels. Excessive critical voltage fluctuations often cause non-uniform images in conventional LTPS TFT panels; this typically results in a low production yield and difficulty in increasing panel size. CMO's LTPS TFT panel technology -- which ensures outstanding performance and consistency -- can be used in OLED TV panels offering extreme thinness, an ultra-wide viewing angle, ultra-high contrast, and ultra-fast response time. CMEL has also developed passive matrix OLED (PMOLED) products as well as 2.0" and 3.5" active matrix full-color OLED panels using CMO's unique LTPS TFT technology. CMEL will exhibit its new products from Oct.18 to Oct. 20 at the FPD International 2006 in Yokohama, Japan.
