Sharp aims 1000ppi IGZO display for VR

October 06, 2016 // By Julien Happich
At Ceatec Japan 2016, Japanese display maker Sharp dedicated a whole area of its gigantic booth to Indium gallium zinc oxide (IGZO), a transparent crystalline oxide semiconductor technology that Sharp uses as a backplane to drive various types of displays.

One of the claims Sharp makes on its website is that thanks to the high electron mobility of IGZO, it was able to achieve unprecedented transistor miniaturization and circuit thinning, raising light transmission at pixel level while doubling display resolution.

In the IGZO area, the company unveiled a very high definition IGZO display specifically aimed at Virtual Reality headsets, boasting 1920x2160 pixels on a 2.87" unit at 1008ppi. To prove that at this resolution, pixels cannot be distinguished by the human eye, even when magnified by a VR lens, two panels were exhibited side by side, one naked, and another one with a lens in front of the panel. With 1920x2160 pixels in front of each eye, that makes for a 4k (3,840x2,160) VR headset.

The 1008ppi resolution is to be compared with 806ppi announced by Sony on its Xperia Z5 Premium smartphone last year, Samsung Galaxy Note 7's 518ppi resolution or the Oculus Rift's 461ppi display.
