摘要
我们报告了第一个1700像素每英寸(PPI)的无源矩阵蓝色发光二极管硅(LEDoS)微显示器。通过将微型led阵列倒装到ASIC显示驱动器上，我们成功地制作了分辨率为256 x 192的0.19英寸显示屏，这是基于led的微显示器中最高的。此外，LEDoS微型显示器可以提供高达1300 mcd/m2的亮度，并以6位灰度呈现图像。卓越的性能表明LEDoS微型显示器在高性能、小尺寸和低功耗的便携式显示应用中具有巨大的潜力。
1700 Pixels Per Inch (PPI) Passive-Matrix Micro-LED Display Powered by ASIC
We report the first 1700 pixels per inch (PPI) passive-matrix blue light-emitting diodes on silicon (LEDoS) micro-displays. By flip-chip bonding a micro-LED array onto an ASIC display driver, we successfully fabricated a 0.19-inch display with a resolution of 256 x 192, the highest ever reported in LED-based micro-display. In addition, the LEDoS micro-display can deliver brightness as high as 1300 mcd/m2 and render images in 6-bit grayscale. The remarkable performance suggests the tremendous potential of LEDoS micro-displays for portable display applications which require high performance, small size and low power consumption.
