Future AR headsets, according to Samsung Display, will use LEDoS (or micro-LED) instead of OLEDoS (or micro-OLED). LG Display concurs, but believes that OLEDoS in VR headsets has a promising future.
OLEDoS, also known as micro-OLED, or OLED displays built on silicon wafers – similar to microchips – for very high pixel density, is slated to begin manufacturing with the release of the Apple Vision Pro early next year.
OLEDoS is most likely to be used in VR devices, according to LG Display, who spoke at the Deep Tech Forum organized by Korean TheElec in July.
However, LEDoS (LED on Silicon) is anticipated to take the role of OLEDoS for future AR headsets, according to Gong Min Kim, Head of Technology Strategy at Samsung Display. Regarding AR devices, LG Display concurred.
According to Samsung Display, micro-OLED has limitations in terms of brightness, form factor, and lifespan.
Authentic micro-OLED
Samsung Display acknowledged that it has begun to develop LEDoS technology for AR devices because it thinks it can resolve the present problems with display production and quality.
Making LEDs tiny enough, in the 10–20 micrometer range, is the key problem because existing production techniques dramatically impair performance and attributes in this range.
Current low-end and mid-range headsets from Meta feature traditional LCD displays with an LED backlight, as do older headsets. The PlayStation VR 2 from Sony has OLED.
How to reach 10,000 nits of brightness
According to Samsung Display, it is researching the use of RGB LEDs and blue LEDs with red and green quantum dots, which is similar to QD-OLED but uses a blue LED rather than a blue OLED for micro-LED.
Increasing brightness to the milestone of 10,000 nits is one important objective. According to LG Display, at least another five years will pass.
