Japan Display Inc. (JDI) announced the development of a 3.60-inch 803ppi low temperature polysilicon (LTPS) TFT LCD specifically designed for virtual reality (VR) head mount display (HMD) applications. JDI is accelerating development of even higher [resolution/pixel density] LCDs for HMD and plans to finish development of over 1000ppi in the first half of 2018.
JDI's LTPS TFT LCD for HMD that is currently in mass production has a super-fine pixel density of approx. 600ppi, which provides a sense of reality to users. The company said it realized that a pixel density even over 600ppi is not sufficient to avoid seeing the pixel structure in all cases, and that a display with pixel density of 800ppi is necessary. Furthermore, in order to decrease the size and weight of the [HMD/device], both decreasing the size of the display and increasing the magnification of the lenses are effective – which requires even higher pixel density of 1000ppi or higher.
The amount and speed of the display data which a VR-dedicated-HMD processes is much greater than a smartphone. Therefore, the receipt of VR-dedicated-HMD display data via current telecommunication networks is practically not possible, and most VR-dedicated-HMDs use hard-wired systems. However, when the next generation 5G network comes into place, HMDs will be able to receive the required display data via the telecommunication network, which will enable the broadening of VR applications and services. We expect the market size of VR-dedicated-HMDs will expand along with the expansion of 5G networks.
