What is microLED display technology?

  • MicroLEDs are self-illuminating diodes that have brighter and better colour reproduction than Organic Light Emitting Diode (OLED) display technology.
  • Apple is currently working on this new display technology and plans to implement the same on future watch models starting 2024, and gradually to its other devices including iPhones and Macs.
  • The basis of microLED technology are sapphires. A sapphire can shine on its own forever.
  • A microLED screen is filled with such small but strong light. The picture in a microLED screen is generated by several individual light-emitting diodes.
  • Samsung, the pioneer in microLED technology explained in a video that a microLED is as small as cutting a centimetre of hair into 200 smaller pieces.
  • Each of these microLEDs are semiconductors that receive electric signals. Once these microLEDs are gathered, they form a module.
  • Several modules are then combined to form screens.

What are its benefits over other displays?

  • MicroLED displays are brighter, have better colour reproduction and provide better viewing angles.
  • They make images appear as if they painted on top of the device’s glass and are quite the technological feat.
  • MicroLEDs have limitless scalability, as they are resolution-free, bezel-free, ratio-free, and even size-free.
  • The screen can be freely resized in any form for practical usage.
  • In addition to being self-emissive, MicroLEDs also individually produce red, green, and blue colours without needing the same backlighting or colour filters as conventional displays, according to Samsung.
  • The electronics company is currently the world’s most advanced manufacturer of displays, and has been producing its own version of microLED for TVs.
  • Samsung and LG Displays have evolved with brighter OLED panels over the last couple of years but microLED promises even greater luminance without panel degradation issues.
  • Samsung has come up with MicroLED displays with up to 4,000 nits of peak brightness, roughly double of what the best OLED and LCD TVs are capable of right now.
