Sharp reveals a 4.1 inch display with a resolution of 2560 X 1600 (WQXGA), codenamed IGZO. What is so special about this is it has the same PPI as a 6-inch, 4K display. This was made possible with the use of transparent crystalline oxide semiconductors that is made of indium, gallium, zinc and oxygen which is the inspiration for it’s name.
Sharp claims that they are the first company that are able to mass produce this kind of display. They also claimed that IGZO’s power consumption actually reduces power to a fifth or even a tenth of conventional displays. Despite allaying this fear of power consumption, there is a real lack of capable mobile CPUs that can run a smooth 4K resolution right now.
At a mind blowing 736ppi with pixels of 11.5µm in size, this is certainly a technological marvel to say the least. To put it into perspective, an iPhone 6 has a ppi of only 401. Sharp plans to roll out prototypes with this tech next year and aiming for mass production in 2016.
