Think of a 4K 3840 x 2160 pixel display with a pixel density of 734ppi for your 6-inch smartphone. Seems a bit of overkill? Well, a Chinese company Everdisplay has announced the development of such a screen.
The AMOLED panel maker Everdisplay aka Hehui Optoelectronics (its Chinese name) has developed the world’s first 4K UHD 6-inch diagonal AMOLED display panel with a whopping 734ppi pixel density. A working prototype of such record breaking featured panel has been unveiled by the company in China. According to Everdisplay, such high-resolution display panels will be required for emerging new applications including virtual reality.
The company had started mass production of 5” 720p AMOLED displays in late 2014. It is also developing various other display panels such as 5.5” and 6” ones for smartphones, 1.4” 400 x 400 round AMOLED ones for smartwatches and also an 8” AMOLED panel for the Automobile sector.
Although a display panel with 734ppi is quite high compared to what is currently used, there are other companies who have developed display prototypes with higher ppis. The highest density display in the world in production is made by Sharp which is the 5.5” (2160 x 3840) 4K IGZO LCD display with 806ppi. SEL of Japan has developed a 2.8” panel prototype with 2560 x 1440 resolution achieving a ppi of 1058!
In AMOLED displays, the current record is held by Samsung Galaxy S6 which has a 5.1”QHD 577ppi super AMOLED panel. Last month, Samsung announced that it was planning to develop super-high 11K mobile displays with a pixel density of 2250ppi!
As for the 6-inch (3840 x 2160) 4K 734ppi display, Everdisplay has not disclosed when it will enter mass production.
