AU Optronics today unveiled a 2.2" transflective panel with the world's slimmest border of 0.9mm and a 2.7" panel with contrast ratio of 2100:1.

In terms of mobile devices applications, due to the increasing needs of high contrast ratio and wide viewing angle, the border width for small-sized panel is becoming increasingly important. AUO’s 2.2” mobile device TFT-LCD possesses the world’s slimmest border of 0.9mm on both the right and left sides. This is a half size smaller than current products on the market today. In addition, the upper side border width can be reduced to merely 1.2mm.

By using novel domains-forming technology along with specific pixel structure design, AUO’s AMVA-mobile technology is able to maintain stable liquid crystal molecular directions, prevent press mura, and provide higher transmittance. Also, by utilizing leading Multi-domain Vertical Alignment design, the AMVA-mobile technology effectively restrains dark state light leakage and increases the aperture ratio, resulting in a higher contrast ratio of up to 2100:1. AUO AMVA-mobile technology has been successfully applied on 2.7” mobile QVGA resolution mobile displays to fulfill the needs of video calls and movie-playing.

"The arrival of the 3G era accelerates mobile handsets to become lighter, thinner, brighter, more elegant and more interactive human-interfaced. To enhance contrast ratio and improve motion blur is also crucial for mobile devices displays," said Dr. CT Liu, AUO Vice President & GM of Consumer Product Display Operations. Thus, AUO has successfully implemented large-sized TFT-LCD technologies to small- and medium-sized displays, including AMVA-mobile technology, ASPD-mobile technology and APE-mobile technology.

APE-mobile technology can enhance the image contrast and reduce system power up to 50% and maintain image luminance. Dr. Liu further stated that in the future, these mobile device-exclusive technologies will be the competitive niche for AUO in the consumer electronics and mobile phone markets.
