Why in news?

  • Apple is reportedly working on a new display technology called microLEDs, which is considered the next big thing in the display industry.

About Micro-LEDs:

  • MicroLEDs are self-illuminating diodes that have brighter and better colour reproduction than Organic Light Emitting Diode (OLED) display technology.
  • MicroLED technology is based on the use of sapphires, which are known for their ability to shine on their own indefinitely.
  • The technology involves the use of tiny light-emitting diodes (LEDs) that are packed tightly together to create a bright and high-quality display.
  • Unlike OLED displays, microLED displays use inorganic material such as gallium nitride.
  • 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:

  • Brighter screens with better colour reproduction and viewing angles.
  • Limitless scalability, as microLED displays are resolution-free, bezel-free, ratio-free, and even size-free.
  • The ability to freely resize the screen in any form for practical usage.
  • Self-emissive microLEDs that individually produce red, green, and blue colours without needing backlighting or colour filters.

Challenges:

  • The process of manufacturing microLEDs is highly complex, and it requires precise control over many variables to produce high-quality displays.
  • The cost of manufacturing microLED displays is currently very high, and it may take some time for the technology to become affordable enough for widespread adoption.
  • MicroLEDs require a lot of power to operate, which can make them less energy-efficient than other display technologies.

PRACTICE QUESTION:

With reference to ‘Micro-LEDs’, consider the following statements:

1. It consumes less power as compared to Organic Light Emitting Diode (OLED) display technology

2. It have brighter and better colour reproduction

Which of the statements given above is/are correct?

(a) 1 only

(b) 2 only

(c) Both 1 and 2

(d) Neither 1 nor 2
