In a recent development, international tech firm AU Optronics has announced the launch of its latest 4.46-inch mobile phone touch panel display that the company claims to be the world’s narrowest border with a high resolution of HD720 and the width of mere 1mm from display area to touch panel border, maximizing the display area available.
Reportedly, the display uses proprietary technology allowing for incredibly thin borders and uses low-temperature poly-silicon (LTPS) technology. The technology allows the display to have a border width of only 1 mm when placed on the module surface.
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 also notes that the 1 mm thick border makes image and video content appear larger. AUO has flaunted its other display technologies including AMOLED, IGZO, and AHVA.
AHVA is Advanced Hyper-Viewing Angle. So far, AUO has been able to develop AHVA panels ranging in size from three-inches to 15.6-inches. The screens have been used in devices such as digital cameras, smartphones, e-readers, and car displays, tablets, and ultrabooks. AUO’s 4.97-inch full HD resolution AHVA Mobile Display is currently in mass production.
Further, 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.
