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.
