With the rise of mixed reality/virtual reality (MR/VR), related display requirements have also received a great deal of attention. MR is represented by Microsoft's HoloLens. VR is represented by HTC VIVE and Oculus Rift. The head-mounted devices used by them are very close to the eyes. The ideal pixel density of the display is 2000ppi, which is far beyond the current LCD and OLED displays. The level, but Micro LED is expected to achieve this goal, become the MR / VR headset device the best display technology.
There are two main requirements for MR/VR head-mounted displays: response speed and pixel density, both of which Micro LED can meet. The LCD cannot achieve the response speed required by MR/VR because of its material properties, and the display delay during use greatly reduces the product experience. Although the OLED response speed is fast, the pixel density reaches its limit at about 1000ppi, which cannot satisfy the high demand of MR/VR 2000ppi.
In terms of the requirements for the substrate, Micro LED also has a higher flexibility, for the glass substrate, PCB substrate or flexible substrate Micro LED can be perfectly adapted. Although Micro LED has unique advantages in the field of MR/VR, mobile phones and televisions using LCD and OLED panels are still mainstream consumer products. With mature technologies and low cost, Micro LED still has a long way to go before it is popularized.
