Why in news:
- Apple’s shift to microLED display technology is reportedly under process.
- 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.
What are MicroLED displays and the technology around it?
- MicroLEDs are selfilluminating diodes that have brighter and better colour reproduction than Organic Light Emitting Diode (OLED) 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 lightemitting diodes.
- 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.
Benefits associated with the technology of microLED display:
- According to a report by Bloomberg 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 resolutionfree, bezelfree, ratiofree, and even sizefree.
- The screen can be freely resized in any form for practical usage.
- In addition to being selfemissive, MicroLEDs also individually produce red, green, and blue colours without needing the same backlighting or colour filters as conventional displays.
Challenges associated in adoption of this technology:
- Apple had planned to start the transition to microLED screens as early as 2020.
- But the project languished due to high costs and technical challenges.
- Apple’s 2024 target could potentially be extended to 2025.
- The company could also offer a limited supply of the new devices to get the transition started.
