With ultra high 10,000:1 contrast ratio and less than 1 ms response time, it displays immaculate quality motion pictures. Its exceptional capabilities make it ideal for handset filming or broadcasting multimedia MTV, which are increasing in market demand. This particular 2" AMOLED model is scheduled for mass production targeted for the higher-end markets. Another eye-catching handset model is a brand new 2.4" AMOLED mobile phone panel with QVGA resolution that is also attractive.

In the LTPS Technological showcase area, on display is the 2.2" LTPS panel produced via PMOS technology. PMOS as compared to CMOS production has substantial cost savings as it can save up to 2-3 TFT mask processing. This technological development enables AUO's LTPS production to be more cost effective with competitive yields. Within the LTPS product line already in production, the most prominent is the 2.5" LTPS DSC application panel, qualified with 960x240 high resolution. These qualities may become the up and coming trend for future DSCs.

Also at its debut, the 1.6" 262k color TFT-LCD handset panel, targeted as a replacement for Color STN-LCD handset panels. Scheduled for mass production in 3Q 2005, AUO's 2.2" LTPS thin and slim module for mobile phone application has quality specifications of high brightness, high resolution, high color saturation, high density, and premium wide viewing angle. This model is ideal for the middle-high handset market, ready to quench the new wave of demands for handsets industry.
