An LG Display executive had said the company believes that OLED on silicon (OLEDoS) will be the main display used in future metaverse devices.

LG Display vice president Yang Joon-young said during TheElec Metaverse Conference held in Seoul on Friday that technology around OLED has improved in recent years and this was leading the industry shift from liquid crystal on silicon (LCoS) to OLEDoS when it comes to microdisplays.

Microdisplays refer to displays that are around 1-inch in size that is used in augmented and virtual reality devices.

These displays use silicon as the substrate instead of glass, which allows them to reach ultra-high definition despite the stronger screen size.

LCD on silicon is called LCoS and OLED on silicon OLEDoS. There is also LEDoS, which has LED on the silicon substrate.

Yang told the conference that VR devices need to use high-resolution screens of at least 60pixels per degree to avoid the screen door effect, where the lines between the pixels are visible.

The technology needed for this is more sophisticated than 1000 to 2000pixels per inch used currently, the VP said.

Next generation VR devices will use OLEDoS with 3000pixels per inch or higher resolution as well as over 5000nit in brightness, Yang explained.

For AR, OLEDoS had an advantage in making the form factor small making it the optimal display for the device, the LG Display executive said. Existing LCoS can be used for low-end AR devices instead.

However, Yang noted that LEDoS was a viable competitor to OLEDoS and that the company was continuing to watch its technology development as well.

LG Display is currently developing an OLEDoS that uses white-OLED with a color filter.
