MicroLED technology is a next-generation emissive display technology that promises highly efficient and bright displays that offer superior image quality with infinite contrast and a wide color gamut.

MicroLED can be applied to displays of many kinds - from small displays for smartwatches and AR devices to large-area TV displays.

Tiled MicroLED TV displays

One unique feature of microLED technology is the ability to create seamless large-area displays made from small display tiles. This unique feature is interesting because it can creates extremely large displays in which the cost grows linearly with display size, unlike standard LCD and OLED TV displays which grows exponentially more expensive as display grows.

Several companies developed such tiled display technology, including Sony, Samsung, Konka, LG and others. Tiled large-area microLED TVs are available on the market today, but prices are very expensive and these are highly premium devices. Are you looking to buy such a TV? Check out our 2021 MicroLED TV buying guide. Not much has changed from 2021, as microLED TVs are still extremely expensive ($100,000 and over).

One interesting thing to note is that while most so-called microLED TVs are indeed emissive displays, the actual LED chips inside these TVs are not always miicroLEDs, but sometimes actually mini-LEDs (this is true for example in Samsung's TVs, at least for the first-gen models).

Consumer MicroLED TVs

Companies are also developing consumer-grade MicroLED TVs. The main challenge is bringing the cost down by a factor of around 100X, even if targeting the premium consumer TV market. Producing such consumer MicroLED displays at competitive prices is a huge challenge due to the extreme number of microLED chips - a 4K TV requires almost 25 million individual microLED chips - and these need to be produced on a wafer and transferred to the final TV substrate.

It will likely take many years before consumer MicroLED TVs at affordable prices can be produced.

LG launches microLED MAGNIT displays for virtual production

LG Electronics launched a new version of its microLED MAGNIT displays, specifically for virtaul production (model LBAF). The new model is designed to help directors to create immersive visual experiences, ideal for film and media production.

The new MAGNIT TVs feature LG's chip-on-board (COB) LED technology and a 1.5mm pixel pitch. LG's previous microLED displays were available in four four pixel pitch options - 0.68, 0.78, 0.94 and 1.25 mm.

MicroLED Tiled Displays - current status and future roadmaps

The MicroLED Industry Association published today a new white paper, that is focused on Tiled MicroLED TVs. One of the advantages of microLED technology is the ability to create completely seamless tiled displays, offering unique cost and design advantages. Tiled microLED displays are already on the market, but available displays are extremely expensive, targeting the commercial and ultra-premium residential markets.

This whitepaper discusses tiled microLED displays, the current market and industry status, the technologies required to produce such displays, the roadmap ahead – and also a microLED tiled TV chip cost analysis and a discussion on how could such displays compete with premium OLED TV displays.

The white paper is published on the MicroLED Association's website, and is open to the public.
