Sharp develops 4K smartphone screen, undecided on manufacturing plan

Sharp has developed a 5.5-inch display with 3860 x 2160 pixel resolution, which is equivalent to "ultra high definition," also known as 4K.

The prototype LCD display, which could be used in smartphones in the future, has a pixel density of 806 pixels per inch (ppi) and was shown off last week at the China Information Technology Expo in Shenzhen, China. It was part of a larger, 12.5-inch IGZO panel.
