JDI Announces Development of High-Pixel-Density 803ppi LCD
Specifically-Designed for Virtual Reality Applications
- Paving the way to even higher pixel density over 1000ppi -

December 12, 2017 (Tokyo, Japan) - Japan Display Inc. (JDI) today 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 will accelerate the design of even higher resolution displays for VR-HMD applications by completing development of a TFT LCD with over 1000ppi pixel density in the first half of 2018.

Currently, JDI's LTPS TFT LCD in mass production for HMD applications has a super-fine pixel density of approximately 600ppi, which provides a sense of reality to users. However, 600ppi-class displays are still not sufficient to prevent users from noticing pixel grid lines (i.e., pixelation), and a display with 800ppi or higher pixel density has been anticipated by our customers. Also, in order to decrease the size and weight of the HMD device, even higher pixel density of 1000ppi or more adopted into smaller displays using lenses with higher magnification, is required.


Comparison of Pixel Density

Today, the amount and speed of the display data required for VR-dedicated-HMD processing is much greater than that of a smartphone. Therefore, the receipt of real time data by VR-dedicated-HMDs via current telecommunication networks is practically not possible and most VR-dedicated-HMDs use hard-wired systems. However, when the next generation "5G network" becomes reality, HMDs will be able to receive data in real time via wireless telecommunication networks, which will enable the broadening of VR applications and services. We expect the market size of VR-dedicated-HMDs will expand along with the spread of 5G networks.

JDI will continue to strive to maintain its leading position in high-pixel-density displays for VR-dedicated- HMDs by leveraging its long experience in the development of LTPS TFT LCDs.

* ppi is an abbreviation for pixels per inch.
* JDI defines "VR-dedicated-HMD" as a head mount device which mounts displays specially-designed for virtual reality applications, whereas there are other types of HMDs which mount actual smartphones as the display user-interface instead. there are HMDs which use displays designed for smartphone applications instead.
