In South Korea, they created a microdisplay with a record pixel density of 12,000 ppi - it interested Qualcomm and not only.

Published: 2023-01-13

The active movement of high-tech towards virtual and augmented reality creates a need for high-resolution microdisplays to make the digital world look as realistic as possible. It is believed that this requires microdisplays with a pixel density of at least 3000 dots per inch (ppi). The South Korean company Raontech has surpassed even the wildest expectations and introduced a microdisplay with an unprecedented density of 12,000 ppi.

The message about the new development came from yesterday's meeting with the company's management. The record was achieved for LCoS technology or liquid crystals on silicon. Before the rapid development of AR and VR technologies in recent years, LCoS displays were widely used for the production of projectors. Leading display and microdisplay manufacturers, such as LG Display, consider OLED-on-silicon (OLEDoS) microdisplays, rather than LCoS, to be the most promising for virtual and augmented reality. Raontech is trying to prove the disputability of such a statement in practice and claims that there are many customers for the technology.

CEO Bo-eun Kim explained, “We have served more than 200 customers not only in AR, but also in medical solutions and optical communications. 70–80% of our clients are foreign customers.” Thus, this factoryless developer shows that he is aimed at the global market. Thus, a reference microdisplay with a record pixel density was sent to Qualcomm at the end of last year. It cannot be ruled out that the Raontech display will fall into Qualcomm's reference AR glasses based on the Snapdragon AR2 chip and will be widely demanded in the industry.

Raontech is now preparing to go public, which is expected in March through a SPAC merger with Daishin Balance. This will raise additional funds for the development of more advanced displays and not only LCoS, but also using LED technology.
