Emerging flat-panel display technology
MicroLED, also known as micro-LED, mLED or μLED is an emerging flat-panel display technology consisting of arrays of microscopic LEDs forming the individual pixel elements. Inorganic semiconductor microLED (μLED) technology[1][2][3][4] was first invented in 2000 by the research group of Hongxing Jiang and Jingyu Lin of Texas Tech University while they were at Kansas State University. The first high-resolution and video-capable InGaN microLED microdisplay in VGA format was realized in 2009 by Hongxing Jiang and Jingyu Lin and their colleagues at Texas Tech University and III-N Technology, Inc. via active driving of microLED array by a complementary metal-oxide semiconductor (CMOS) IC.[5] Compared to widespread LCD technology, microLED displays offer better contrast, response times, and energy efficiency.[6]
MicroLED offers greatly reduced energy requirements when compared to conventional LCD displays while also offering pixel-level light control and a high contrast ratio.[6][7] The inorganic nature of microLEDs gives them a longer lifetime advantage over OLEDs and allows them to display brighter images with minimal risk of screen burn-in.[6] The sub-nanosecond response time of μLED has a huge advantage over other display technologies for 3D/AR/VR displays since these devices need more images, more pixels per image, more frames per second and fast response.[6] MicroLEDs are capable of high speed modulation, and have been proposed for chip-to-chip interconnect applications.[8]
As of 2021[update], microLED displays have not been mass-produced, although Sony, Samsung, and Konka sell microLED video walls.[9][10][11][12][13][14] LG, Tianma, PlayNitride, TCL/CSoT, Jasper Display, Jade Bird Display, Plessey Semiconductors Ltd, and Ostendo Technologies, Inc. have demonstrated prototypes.[15][16][17][18][19][20][21][22] Sony already sells microLED displays as a replacement for conventional cinema screens.[23] BOE, Epistar, and Leyard have plans for microLED mass production.[24][25] MicroLED can be made flexible and transparent, just like OLEDs.[26][25]
According to a report by Market Research Future, the MicroLED display market will reach around USD 24.3 billion by 2027.[27] Custom Market Insights reported that the MicroLED display market is expected to reach around USD 182.7 Billion by 2032.[28]
