Problem
Manufacturing high-resolution, tri-colored microLED displays currently suffers from limitations such as poor resolution, expensive capital equipment, low throughput, and high manufacturing costs. Existing methods struggle to efficiently pattern quantum dot downconverter layers needed for full-color displays.
Solution
NanoPattern develops photopatternable quantum dot inks that enable the manufacturing of high-resolution, tri-colored microLED displays at reduced costs. Their patented ink formulations and direct nanoparticle lithography process allow for efficient patterning of quantum dot downconverter layers, addressing the unmet needs of current display manufacturing methods. The ink can be coated, exposed with a mask and UV light, and developed into a pattern using conventional photolithography. This process is fully compatible with existing equipment and offers a parallel patterning approach.
Target Audience
The primary target audience includes display manufacturers looking to produce high-resolution microLED displays for applications such as augmented reality (AR) and virtual reality (VR) headsets.
Features
