AU Optronics Corp., today announced the world's narrowest border (*) on its 4.46-inch cell phone and touch panel integration technology. 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 constantly drive the trends for ultra high resolution, ultra wide viewing angle and super narrow border technologies.
"As portable smart devices become prevalent and the size of mobile displays grow larger, audio-video entertainment, interactive games and content downloading have emerged at the top of consumers' demand list," said Mr. T.K. Wu, AUO's VP & GM of Mobile Solutions Business Group. "AUO proactively develops the latest technologies including AMOLED and IGZO and excels by introducing ultra high resolution, ultra wide viewing angle and super narrow border technologies. Mobile devices in the future will become lighter and smaller, color and image quality will also be all the more impressive, offering customers even more innovative solutions to choose from."
AUO has successfully 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 camera, smartphone, e-reader, car display, tablet and Ultrabook. 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 1080x1920 (443ppi). The display is to satiate consumers' ultimate quest for exquisite image quality.
Industry-Leading Ultra High Resolution, Super Narrow Border and Ultra Wide Viewing Angle Technologies
AUO is the first to present the world's narrowest border on its 4.46-inch cell phone and touch panel integration technology, with a high resolution of HD720 and the width of mere 1mm from display area to touch panel border, maximizing the display area available. Image and video content appear larger in frame size, and also better in quality.
With the resolution of current OLED panels ranging from 200 to 300ppi, AUO reveals 4.65-inch AMOLED panel technology which employs the Company's proprietary pixel design with resolution as high as 317ppi. The panel is capable of exhibiting sharper quality for texts, and refined and realistic image property. Meanwhile, power could be saved to prolong the OLED lifetime.
AUO is also introducing 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, which delicately demonstrates the fineness and details of the image. 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. The features herald the trend towards power-saving slim displays with high resolution.
