On May 14th, Japan Display (JDI) of Sony, Toshiba, and Hitachi Group stated that it is developing a 3.25 inch LCD screen with a pixel density of 1001ppi, which can bring less delay, power consumption performance and better picture quality for VR devices.
The new technology of JDI is in response to the problem of the screen effect of OLED screens commonly used in modern VR devices. Compared with the 1001ppi screen provided by the official, this is actually better than the 803ppi screen launched by JDI last year. As the picture quality improves, the size of the screen is further compressed, making it suitable for use on smaller, lighter head-mounted devices. Moreover, the screen response time is also reduced from 4.5 microseconds to 2.2 microseconds and can be played stably with 120Hz high-brush frames, and the VR content image can be smoother and more natural.
Quoted from the news of Expreview, Japan's screen maker JDI recently announced an ultra-high PPI screen designed for VR headsets. The screen of VR used by JDI is LTPS LCD panel. The resolution is 2160*2432. The PPI is 1001, which greatly improves the problem of large particles in the current VR viewing to provide a better immersive experience. The vr glasses are a new and popular area in recent years. It is difficult to avoid more and more companies developing new technologies and entering this field.
The advantage of the JDI screen is that it is an LCD panel. Pixels are arranged in standard RGB and have a response time of 2.2ms, which is faster than the current common 4.5ms. The low response time can reduce the blurring caused by the rapid change of the screen, and the refresh of the screen. The rate of 120Hz is also better than the 90Hz specification of the existing VR screen, which can bring about lower picture delay.
JDI plans to commercialize this VR HD screen at the end of March 2019, which should be of great help in improving the VR viewing experience. It is worth looking forward to the emergence of related VR head-display products.
