The display allows users to enjoy precise and dynamic images within the resolution range of full high-definition (Full-HD) smartphones, with approximately 4 times larger screen size. Low temperature poly silicon technology (LTPS) enables not only high-capacity information content and high-resolution, but also low power consumption, thinner module and narrower dead-band2, which suits mobile-use devices like tablets.

We will exhibit these displays in Japan Display Inc. booth on October 23 to 25, 2013, during FPD International 2013 in Pacifico Yokohama, Japan.
