Epistar Corp, based in Taiwan and established in 1996, is one of the world's largest LED producers. The company specializes in high-brightness LED devices for general lighting and consumer electronics.
Epistar is developing Micro LED chips but has yet to announce any products or market intentions. Some reports suggest the Epistar is likely to first produce 100-micron LEDs (in 2017) to be used in large displays. This will be followed by smaller LEDs for smaller displays.
In October 2018 Epistar established a wholly-owned subsidiary called Yenrich Technology that develops applications for mini LED and micro LED technologies.
In 2020 Epistar announced a merger with fellow Taiwanese LED maker Lextar.
The latest Epistar MicroLED news:
Taiwan-based PCB developer Unimicron has started to develop specific PCBs for Micro-LED displays, with aims to start mass producing such PCBs in 2019. According to LEDsInside, Unimicron will start a small batch production in 2018.
Unimicron is collaborating with Epistar's and ITRI's micro-LED display alliance, hoping that this will speed up the commercialization of its technology. LedsInside also reports that other Taiwan-based PCB makers aim to also start developing specific solutions for Micro-LED displays.
Digitimes posted an interesting interview with Epistar's president, Jou Ming-Jiunn. Jou says that the most optimistic scenario is for micro-LED displays to enter production by the end of 2018, with real devices appearing in 2019. There are still challenges ahead though, and Epistar's customers have not yet committed to anything.
According to Jou, there are two main routes to the market for Micro-LED makers: VR/AR or wearable displays and large-area TV panels. It is not clear yet which will route will arrive first.
