　　OLED displays have been used in VR headsets for years due to their responsiveness and pure black display.

However, Samsung Display general manager Kim Min-woo said the company is developing a Micro-LED-based AR display technology　　, The Elec reported . The technology is called Micro-LED on Silicon ("LEDoS" for short).

　　It is understood that the difference between AR (Augmented Reality) and VR (Virtual Reality) is that AR requires a brighter display as it will compete with ambient light, projecting virtual images into the real world needs to match the lighting around the user brightness.

　　A VR display, on the other hand, isolates the user from the world, and only uses lower brightness to get the job done.

　　So Micro-LEDs have advantages over OLEDs because they have high brightness, higher resolution, longer lifespan, and even better form factors.

　　Samsung's goal is to develop LEDoS displays with 6600 pixels per inch (PPI). According to Kim, AR displays have a minimum of 5,000ppi and a maximum distance between pixels of 5 microns. The red, green and blue subpixels are at most 3 microns. This shows that technology needs to advance by leaps and bounds to get a realistic display.
