This technology proposes the preparation of Anodic Aluminum Oxide (AAO) templates on the surface of aluminum. The structural color of AAO is combined with lithography process to form patterns on the substrate, which can achieve high resolution on various aluminum substrate for decoration. Also, rewritable boardinvisible anti-counterfeiting technology are proposed for innovative applications by the low-cost, high-efficiency,high-saturation AAO structural colorpatterning.

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.

A novel 3D-stack LTPO-based display array technology with CBRAM-embedded in a pixel has been successfully developed for the high-resolutionpower-saving near-eye VR/AR displays. Besides, a high-voltage gain CMOS inverter comprised by LTPO architecture is demonstrated acting as a digital driving circuit for the realistic FPD applications.
