Sharp has announced a 4K display for smartphones. The screen with a resolution of 3840 x 2160 pixels has a diagonal of slightly less than 5.5″. It’s the first time a company announces a 4K display for smartphones.
The highest resolution currently available on commercially available smartphones, with a 16:9 display ratio, is 2560 x1440 pixels, which can be found on e.g. the Samsung Galaxy S6 and LG G3. The Chinese Meizu MX4 Pro has a resolution that’s slightly higher, 2560x 1536 pixels. Sharp’s 4K smartphone display was announced during CITE 2015, a Chinese technology exhibition held last weekend.
The screen has 806 pixels per inch, which results in a diagonal of 5.47″, making it the highest pixel density of a screen currently available. According to Sharp, the screen has a RGB layout and will go in mass production next year which makes it likely the company will also release its first 4K smartphones next year.
