For augmented reality (AR) headsets, Samsung is purportedly developing “MicroLED on Silicon” (LEDoS).
Since many years, OLED (organic light-emitting diode) displays have been utilised in VR headsets; nevertheless, the business is currently working on MicroLED-based next-generation technology for AR displays. Displays are currently built on glass rather than silicon, according to GSMArena.
The 6,600 pixels per inch (ppi) LEDoS panels are the South Korean tech giant’s long-term goal, according to the article.
A minimum pixel density of 5,000 ppi and a minimum pixel spacing of five micrometres or fewer are required for AR displays, according to Kim Min-woo, the head of the Samsung Display group. Red, green, and blue subpixels shouldn’t be any bigger than three microns each.
In addition to LEDoS, Samsung Display also produces OLED on Silicon (OLEDoS) panels. However, the paper stated that because MicroLED is brighter, it is more suited for AR applications.
In contrast to virtual reality (VR), augmented reality (AR) incorporates virtual objects into the real environment and must match the brightness of the light surrounding the user.
However, since the VR screen isolates the user from the outer world and lower brightness can still be useful, VR only uses virtual reality.
