Color Conversion Solution for Full Color Micro-LED Displays
Micro-LED display has been getting a lot of attention in the last couple years due to its potential to deliver high peak brightness while consuming significantly less power than any of the existing display solutions. Combined with its fast response time, micro-LED display could be the perfect solution for wearables, smartwatches, augmented reality (AR), virtual reality (VR) and mixed reality (MR).
There are basically two ways of implementing micro-LED display, 1) monolithic integration and 2) heterogeneous integration. The monolithic integration approach is an obvious one, however, it usually associates with a higher cost than the other approach. The heterogeneous approach has potential to deliver significantly lower cost but faces huge challenges in manufacturing yield and output. For either approach, it is possible to use red, green and blue (RGB) LED chips together or blue chips only with a color converter such as quantum dots to convert blue into red and green. The latter becomes very attractive due to significant simplification of driving circuitry and manufacturing process.
This talk will discuss in detail the requirements for quantum dot color converters for micro-LED display and the current development status of quantum dots for this application.
