What are microLED displays, and why is Apple shifting to it?

Context

  • Apple’s shift to microLED display technology is reportedly under process. Considered as the next big transition in display technology, microLEDs are self-illuminating diodes that have brighter and better color reproduction than Organic Light Emitting Diode (OLED) display technology.

What is microLED display technology?

  • 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 centimeter of hair into 200 smaller pieces. Each of these microLEDs are semiconductors that receive electrical signals.
  • Once these microLEDs are gathered, they form a module. Several modules are then combined to form screens.

Benefits over other displays:

  • MicroLED displays are brighter, have better color reproduction and provide better viewing angles. They make images appear as if they were painted on top of the device’s glass and are quite the technological feat. Thanks to the long life and ultra-low power consumption, they can be left on all of the time.
  • MicroLEDs have limitless scalability, as they are resolution-free, bezel-free, ratiofree, 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 colors without needing the same backlighting or color filters as conventional displays.
