Japan Display delivers 1001ppi LCDs for VR applications

May 14, 2018 // By Julien Happich
Japan Display has developed a 3.25-inch 2160x2432xRGB 1001ppi low temperature polysilicon (LTPS) TFT LCD specifically-designed for virtual reality (VR) head mount display (HMD) applications.

Last year, the company had announced the development of a high-pixel-density 803ppi LCD but it argues that even more compact-size LCDs and higher magnification lenses are required to decrease the size and weight of HMD devices. Instead, display resolution over 1000ppi is anticipated from the market.

The 1001ppi LTPS TFT LCD not only features high pixel density, but also has improved LC response time from 4.5msec to 2.2msec (gray-to-gray, worst case) which helps to reduce motion blur. In addition to these features, the 1001ppi LTPS TFT LCD is able to operate at 120Hz refresh rate, though most displays for VR-HMD applications operate below 90Hz. This 120Hz refresh rate contributes to minimize system latency.

The company plans to start commercial shipments by the end of March in 2019, and will accelerate the design of even higher resolution displays for VR-HMD applications in the future. The 1001ppi LTPS TFT LCD will be demonstrated in JDI's booth #917 at The Society of Information Display (SID) "Display Week", at the Los Angeles Convention Center, May 22 - May 24, 2018.
