Japan Display Inc. (JDI) has developed a 3.60-inch 803ppi low temperature polysilicon (LTPS) TFT LCD specifically designed for virtual reality (VR) head mount display (HMD) applications.
JDI has been accelerating development of even higher ppi LTPS TFT LCDs for HMD, and will also finish development of an LTPS TFT LCD with over 1000ppi within 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 over 600ppi, which provides a sense of reality to users. However, an even higher pixel density helps avoid seeing the pixel structure in all application cases, so the development of a 800ppi display was necessary. Furthermore, in order to decrease the size of the head mounted device, the size of the display should be decreased, and the magnification of the lenses should be increased. That requires an even higher pixel density for the display, such as 1000ppi.
