Regarding touch panel technologies, AUO will also exhibit its 27” FHD One-Glass-Solution Touch panel and 10.1” AHVA (Advanced Hyper-Viewing Angle) One Glass Solution Tablet. AUO utilizes its One-Glass-Solution to make products slimmer and transparency higher through integrating touch sensors and cover glass. AUO's 27” FHD One-Glass-Solution Touch panel is the world's largest OGS touch panel. It offers Full HD, high-resolution images and supports ten touch points, thus allowing users to move their fingers freely about the surface of the panels. In order to enhance the personal portable flat panel as a high-definition multimedia entertainment center, AUO's 10.1” AHVA One Glass Solution Tablet has been fitted with AHVA technology. Through the total solution, the weight of the product has dropped 33%, making it easy to carry, while still offering WUXGA (1920 x 1200) high-resolution images.
