Sharp has recently introduced a new 5.5-inch screen that designed for smartphone at the China Information Technology Expo 2015 in Shenzhen last week. This high-resolution display is going into production in the future. Based on its specs, the new screen is offering a significant jump up from existing smartphone displays.
New Sharp 5.5-inch Ultra HD 4K IGZO LCD panel features a resolution of UHD 3840 x 2160 pixels and an 806ppi of pixel density. It comes with a 121 x 68 mm of display area. Just comparison, Company was introduced the 4.1-inch IGZO LCD display with a pixel density of 736 ppi last year. Meanwhile, the new one is bigger and sharper.
Sharp 806ppi 4K IGZO panel is made by semiconductor material indium gallium zinc oxide. That claims better clarity rather than TFT panel. The panel gives 10.5µm x 3 sample pixel size, which is a bit better than a 4.7-inch 720p panels with sample pixel size of 27µm × 3.
You probably have to wait more time because Sharp will start mass production of this one in 2016.
