At the "China·Beijing 2016 International Display Industry Summit Forum" held at the beginning of the month, Huang Yibai, professor and vice president of the Department of Optoelectronic Engineering at Taiwan Jiaotong University, said that although AR and VR are hot, there are still many challenges, if anyone can do it with one eye. The VR display, which is deep and not dizzy, can at least get an investment of 800 million U.S. dollars. Huang Yibai pointed out that in view of the current VR display infrastructure, the field of view should be enlarged and the volume will increase. At present, many people are studying how to make VR and AR displays with small size and good angle of view. The first is to let the light hit from the side instead of projecting from above, which can increase the path of the light, enlarge the image, and the volume of the display can be made small. The second is the way of optical waveguides, but the image quality of this solution is not too good. In addition, there are other solutions, but the final form is to make contact lenses, which can ensure small size and ensure a large field of view. He also said that resolution and brightness are the two major constraints of VR display. If the resolution is too low, the graininess of the display will be very obvious, and the user experience will feel uncomfortable. If it is an AR image with background light, it needs at least 1000 lumens in outdoor brightness. If the brightness is too low, the virtual image will block the real image, so many people are studying the problem of shadowing. Huang Baiyi believes that it is necessary to have a pair of eyes to integrate the depth. If it can achieve an AR display with deep and no dizziness, he feels that he can get Alibaba's investment of 800 million US dollars.
