Abstract
Methods of making high-pixel-density LED structures are described. The methods may include forming a backplane substrate and a LED substrate. The backplane substrate and the LED substrate may be bonded together, and the bonded substrates may include an array of LED pixels. Each of the LED pixels may include a group of isolated subpixels. A quantum dot layer may be formed on at least one of the isolated subpixels in each of the LED pixels. The methods may further include repairing at least one defective LED pixel by forming a replacement quantum dot layer on a quantum-dot-layer-free subpixel in the defective LED pixel. The methods may also include forming a UV barrier layer on the array of LED pixels after the repairing of the at least one defective LED pixel.
