TechSpot is about to rejoice its twenty fifth anniversary. TechSpot means tech evaluation and recommendation you can belief.
In short: microLED know-how has an extended approach to go earlier than it could compete with Mini LED and OLED, however AUO has greater than 600 engineers working to make it cheaper to fabricate. Present prototypes depart so much to be desired, however the firm says it’s burning the midnight oil to resolve the remaining points and can progressively shift manufacturing from LCD to microLED over the following few years.
Until you’ve been dwelling beneath a rock, you’ve in all probability heard about Mini LED and microLED, two of a very powerful breakthroughs in show know-how lately. The primary is a extra superior model of LCD the place the backlight includes a dense array of LEDs that permits OLED-like deep distinction ranges (at the price of blooming). The latter is extra akin to OLED in that the picture is straight produced by LEDs with out the necessity for a backlight.
Mini LED has already made its method into some sensible TVs in addition to Apple’s current iPad Professional and MacBook Professional lineups. You may even get a 165 Hz 4K gaming monitor sporting Samsung’s Quantum Mini LED tech for beneath $900, which is a comparatively low worth for a high-end monitor.

As for microLED, now we have but to see it built-in right into a product you should purchase. Apple is claimed to be utilizing the tech in an upcoming Apple Watch, and Samsung up to now has solely used it to make a 165-inch folding TV for lottery winners. Others like Micledi Microdisplays and Kura Applied sciences are centered particularly on perfecting microLED for augmented actuality glasses, a few of which is able to break cowl later this yr.
It’s not for lack of attempting – show corporations have been experimenting with microLED for something from digital signage to smartwatches and all the pieces in between. This week on the Contact Taiwan occasion, AUO confirmed off a number of proof-of-concept merchandise that combine microLED screens and whereas they do look spectacular, in addition they show the tech isn’t fairly prepared regardless of being in improvement since 2012.
One of many prototypes is a laptop computer with a foldable, 14.6-inch show that may attain a most brightness of two,000 nits and will be set from opaque to semi-transparent (as much as 60 p.c transparency) – all nice qualities, a minimum of on paper.
The kicker is the decision, which is a measly 1,280 by 720 – that might have been unimpressive 10 years in the past, not to mention at this time. Oddly sufficient, the corporate additionally demoed a 17.3-inch show with nice anti-glare capabilities however with the identical low decision because the smaller sibling.
AUO says it’s nonetheless engaged on perfecting its microLED tech, and the prototypes present it is extremely a lot a piece in progress, with a number of lifeless pixels seen in some demos. The corporate additionally guarantees to unveil greater decision microLED shows within the not-too-distant future. For now, it solely needed to present a 1.39-inch show for smartwatches with a density of 326 pixels per inch.
Individually, AUO additionally demoed 18-inch and 16-inch AmLED laptop computer shows. AmLED is the Taiwanese firm’s model of Mini LED, and this time we’re speaking a few decision of two,560 by 1,600 – one thing that can work nice for machines designed for use for productiveness. They will attain a peak brightness of 1,000 nits and assist the complete DCI-P3 coloration gamut, with a most refresh charge of 240 Hz.
In associated information, AUO introduced it would progressively convert its current LCD fab in Taoyuan’s Longtan District right into a microLED facility over the following two years. With corporations like Samsung and LG additionally shifting on from LCD tech, the Taiwanese firm expects manufacturing prices for Mini LED panels to drop by 50 p.c each two years, which might significantly enhance its probabilities of success towards OLED and Mini LED options.
