MicroLED, often spelled micro-LED, mLED, or LED, is a new flat-panel display technology that uses clusters of small LEDs to create each individual pixel element. In 2009, Hongxing Jiang, Jingyu Lin, and his colleagues at Texas Tech University and III-N Technology, Inc. developed the first high-resolution and video-capable InGaN microLED microdisplay in VGA format by actively driving a microLED array using a complementary metal-oxide semiconductor (CMOS) IC. MicroLED displays are more energy-efficient, have better contrast, and have faster response times than the widely used Micro-LED technology.
Comparing microLED to traditional LCD panels, you can see how much less energy is needed while yet getting high contrast ratios and pixel-level light control.
