Epistar Corp, based in Taiwan and established in 1996, is one of the world's largest LED producer. 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 application for mini LED and micro LED technologies.

Epistar and Leyard Opto-Electronics to build a $142 million micro-LED and mini-LED production fab in China
Taiwan-based LED producer Epistar is in talks with China-based LED display maker Leyard Opto-Electronic to setup a Mini-LED and Micro-LED production site in Wuxi, China. The two companies (actually Leyard and Epistar's subsidiary Yenrich Technology) will setup a joint-venture with a budget of $142 million.
Leyard says that the plan is to form the joint venture six months after getting the final approval for the plan. This will enable the production to begin in the new fab in 2023. It is still not clear whether the new fab will produce mini and micro LED chips - or actual displays.
Digitimes posted an article on recent advances at Epistar, and according to the article Epistar has achieved a recent breakthrough in micro LED technology. Epistar will unveil the achievement in the second-half of 2018.
Last year Digitimes posted an interview with Epistar's president, Jou Ming-Jiunn, in which 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.
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.
