Taiwanese startup to fuel 5G era with 2228ppi AMOLED displays

January 02, 2019 // By Julien Happich
Founded in 2016 with a vision to enable the oncoming high-bandwidth 5G era and the delivery of ultra-high resolution content, Taiwanese startup INT Tech has developed a proprietary glass-based deposition process to deliver red/green/blue AMOLED displays at pixel densities above 2200ppi.

 

The asset-light company has developed a broad patent portfolio around what it markets as the UHPD platform (for Ultra-High Pixel-Density). The former CEO of Chinese AMOLED display manufacturer EverDisplay Optronics (EDO), INT Tech's chairman and CEO David Chu founded the company two years ago after identifying 5G and high resolution content as the driving forces for tomorrow's display technologies.

While feature phones came with 3G and smartphones followed with 4G, the high bandwidth supported by 5G will drive up content resolution, calling for much higher resolution displays than what's available today, commented the CEO when interviewed by eeNews Europe.

According to Chu, current technology is limiting pixel density and the quality of AR and VR applications that could be supported by 5G, possibly including data-intensive light-field displays. “When 5G arrives, people will no longer be satisfied with 2D images and video", he says.

Although the CEO stated his company was not in a position yet to disclose anything specific about the actual deposition process, he highlighted some of its benefits: the use of readily available and cheap glass substrates (including flexible ones) instead of costly silicon-based substrates as it is the case for other micro-displays. 

"We are not using white OLEDs together with colour filters but truly RGB OLEDs" he added, achieving better light output efficiencies from a thinner display stack.
