In order to achieve natural and realistic motion pictures in VR-HMD devices, the desired display characteristics are: high pixel density, improved motion blur, and low latency. JDI announced the development of a high-pixel-density 803ppi LCD last year, which helped to alleviate problems associated with users noticing pixel grid lines (i.e., pixelation). However, even more compact-size LCDs and higher magnification lenses are required to decrease the size and weight of HMD devices. 800ppi is not sufficient for this purpose. Instead, display resolution over 1000ppi is anticipated from the market.
JDI’s new 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.
By applying this 1001ppi LCD to new VR-HMD devices, users will have enhanced enjoyment of their virtual reality experience, and, further VR market expansion is expected by this technology.
JDI will continue to strive to maintain its leading position in high-pixel-density displays for VR-dedicated HMD devices by leveraging its core technological competency in the development of LTPS TFT LCDs.
