Inkjet printing firm Unijet has supplied inkjet equipment for microOLED to China’s Sidtek, TheElec has learned.
The equipment will be used by the Chinese company in its production of microOLED displays.
The South Korean company had supplied inkjet equipment for thin-film encapsulation (TFE) for MicroOLED, people familiar with the matter said.
TFE inkjet equipment are used to print protective material on the OLED devices to protect them from water and oxygen.
MicroOLED deposits OLED on silicon __ it is sometimes called OLED on Silicon for this reason. The technology is expected to be widely applied for virtual reality and augmented reality applications.
Sidtek was founded in 2016 based in Anhui. Last year, it manufactured a 0.39-inch microOLED display (1024x768).
With the latest deal, Unijet has supplied TFE inkjet equipment for the first time for commercial production.
The company had previously supplied such kits to global companies but they were mostly used for research in pilot production lines.
The latest equipment can print at as thin as 0.5 micrometers. Thinner printing material means it can better block the light emitting from the OLED material to unwanted directions.
Unijet was currently developing inkjet printing technology to reach 0.3 micrometers in thickness for the printed material.
The company’s rival includes US’ Kateeva. Unijet was founded in 2002. Founder Kim Seong-soon previously worked at LG Electronics and Samsung Techwin before forming the company.
