The microLED displays

(MiansGS3:Science and Technology- developments and their applications and effects in everyday life.)

Context:

• Apple’s shift to microLED display technology is considered as the next big transition in display technology.
• Apple is currently working on this new display technology and plans to implement the same on future watch models starting in 2024, and gradually on its other devices including iPhones and Macs.

About microLEDs:

• The microLEDs are self-illuminating diodes that have brighter and better colour reproduction than Organic Light Emitting Diode (OLED) display technology.
• The basis of microLED technology are sapphires as Aa sapphire can shine on its own forever and 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.
• a microLED is as small as cutting a centimeter of hair into 200 smaller pieces and 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 colour 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.
• 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 and 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.
