In autonomous driving, LiDAR can clearly distinguish the objectsget the object information such as speeddistance at medium-range (~100 m) for autonomous driving scheme entering Level 3. Therefore, in this study, we combine the reflective optical phased array (OPA) chip1550-nm VCSELs with a photodetector, a ToF chip,a microcontroller to produce an eye-safe, all-solid-state,low cost (less than $100 USD) LiDAR module, which is the world＇s leading LiDAR technologymore cost-effective than the current products for autonomous vehicle market.

This demonstration presents an active-matrix, 1920x1080, 370 nm UV MicroLED display. There are 2,073,600 pixels fabricated on this display which is smaller than a dollar coin,its diagonal has an extremely high pixel density of 3200 pixels per inch (ppi). The size of each pixel is 5 μm in diameter,the pixel pitch is 8 μm. The key technology of this achievement lies in the fabrication of pixels with good characteristicshigh uniformity,the successful development of flip-chip technology combining MicroLEDdriving integrated circuit pixels. This result can display imagesvideos.
