AU Optronics has applied its narrow border technology to maximize the display area of a new 4.46-inch full-HD touch panel display, designed for mobiles. AUO's proprietary super narrow border technology and low temperature poly-silicon (LTPS) method are applied to reduce the border width to just 1mm when touch panel is placed on the module surface, allowing the screen to appear in its largest at the cell phone's display area. In addition, AMOLED, IGZO (indium gallium zinc oxide) and AHVA (Advanced Hyper-Viewing Angle) technologies are being developed by AUO to drive the trends for lighter and smaller smartphones.

AUO has developed AHVA panels ranging from 3 inches to 15.6 inches and has included them to a full array of mobile device applications, such as digital cameras, smartphones, e-readers, car displays, tablets and Ultrabooks. AUO's 4.97-inch Full HD AHVA Mobile Display, which has entered mass production, is made with LTPS process and has full HD resolution of 1920x1080 (443ppi).

With the resolution of current OLED panels ranging from 200 to 300ppi, AUO also revealed a 4.65-inch AMOLED panel technology, which employs the company's proprietary pixel design with resolution as high as 317ppi.

AUO also introduced its ultra-slim high resolution 10-inch panel technology with application to tablets. The IGZO method is adopted to achieve a high resolution of 2560x1600. With transmittance increased by 12% and thickness of the backlight unit reduced by 60% (as compared to conventional models), the panel is only 1.5mm thick and saves more power.
