Yicai Core Light to start pilot production of perovskite QD-based microLED microdisplays

According to reports, Chinese startup Yicai Core Light will begin mass production of a new microLED display chip that uses perovskite quantum dot technology to achieve a full-color, micro-scale display. The Company is preparing to start producing its microLED microdisplays in the autumn of 2025, in a pilot production line that will be built with help from Ningbo-based Yongjiang Laboratory.

Founder and General Manager Li Fei explained that the chip acts like a 'translator,' accurately converting digital information into the light and images a user sees. Li Fei believes that this technology will improve augmented reality (AR) technology and solve two of the biggest hurdles holding back mainstream adoption of augmented reality glasses: poor outdoor visibility and short battery life.

 

The Company uses perovskite-based quantum dots, saying that these cadmium-free QDs deliver increased performance. Yicai is partnering with application developers including both TCL and Meizu.
