MicroLEDs

Definition

MicroLEDs are tiny, self-emissive light-emitting diodes that serve as individual pixels in displays, offering high brightness, energy efficiency, and excellent color quality. These miniature LEDs provide a promising alternative to traditional LCD and OLED technologies, as they can produce stunning visuals with deeper blacks and higher contrast ratios while consuming less power.

5 Must Know Facts For Your Next Test

1. MicroLEDs can achieve a higher pixel density than traditional LEDs, making them ideal for small-screen applications like wearables and smartphones.
2. The manufacturing process for microLEDs involves transferring microscopic LED chips onto a substrate, which can be challenging and costly.
3. MicroLED technology is known for its impressive response time, making it suitable for fast-moving content in gaming and video applications.
