Smartphone displays have come a long way in the last few years and are now good enough to enjoy TV shows and movies on. But they could get even better in the near future.
Sharp has developed a 5.5-inch display with 3860 x 2160 pixel resolution, which is the equivalent of “ultra-high definition or 4K. The LCD display has a pixel density of 806 pixels per inch (ppi). By comparison, Apple’s iPhone 6 Plus has a 5.5-inch screen with 1920 x 1080 pixel resolution and a density of 401 ppi.
It’s just a prototype for now. Sharp showed off the display at the China Information Technology Expo in Shenzhen. Unfortunately, the company hasn’t decided on a schedule for mass production just yet. Sharp spokeswoman Miyuki Nakayama said, “Currently there are no driver ICs for small 4K panels, so the panel is not ready for mass production at this point.”
Sharp hopes to develop and mass-produce 4K screens for clients’ phones. It may use these displays in its own Aquos line of smartphones, but it’s too early to say for sure.
