Researchers at CEA-Leti developed a new process to produce high performance GaN Micro-LEDs displays, which the researchers say is simpler and more effective than current approaches.

The first step in the new process is transferring the micro-LED chips directly on top of a CMOS wafer. In the second step each complete "pixel", made from a CMOS driving circuit and micro-LED chips, is transferred to the display substrate.

In June 2018, UK-based GaN-on-Si MicroLED developer Plessey Semiconductor and AR developer Vuzix announced a partnership to develop advanced Micro-LED display engines for Vuzix waveguide optics to enable next generation AR Smart Glasses by 2019. Today Plessey announced it has entered into a long-term micro-LED supply agreement with Vuzix.

The new agreement will support the development and production of next-generation AR products that utilize Plessey's micro-LED light source. Vuzix say that the agreement includes an exclusive display device design.

Taiwan-based PMOLED display maker RiT Display announced a strategic partnership and share swap with MicroLED developer PlayNitride. RiTDisplay will have access to PlayNitride's technology and will be able to produce and sell micro-LED panels.

According to the Taipei times, RiTDisplay aims to produce small displays for wearable applications. The article says the display size will be around 3-inch, which actually sounds rather large for wearables.

Earlier this week China-based Tianma unveiled a new 7.56" 720x480 (114 PPI) transparent Micro-LED display prototype at SID, and the display won SID's people's choice award - the best new display technology.

Tianma today revealed that the Micro-LED prototype was co-developed with Taiwan's PlayNitride. In 2017 PlayNitride started to sample micro-LED panels and shipped samples to 10-20 potential customers. The company's chairman and CEO, Charles Li, said in June 2018 that 5-6 of these customers are continuing the developing of micro-LED modules based on these panels. Apparently CSoT is one of these customers.
