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
