OLED Microdisplays: learn more and find a supplier!

OLED is a next-generation display technology that is replacing LCD displays in several markets, such as small displays for mobile applications, TVs and microdisplays. OLEDs are made from thin films of organic light emitting materials that emit light when electricity is applied. OLEDs have a much simpler structure compared to LCDs and have several advantages over the incumbent technology.

OLED microdisplays

OLED microdisplays are considered to be the current state-of-the-art near-eye display technology. OLEDs offer many advantages over competing technologies:

  • No backlight - a direct emissive display with high contrast and a wide color gamut
  • Fast refresh rate
  • Low power consumption (this depends on the image shown)
  • Wide operation temperature range

OLEDs do suffer from lower lifetime, limited market capacity, high price. Many believe that microLEDs will offer the ultimate solution for microdisplays, with their inherent high brightness and efficiency, but these displays are not commercial yet.
