MicroLED is coming. Ever since we set eyes on Samsung\u2019s \u2018The Wall\u2019 at CES 2018, we've been looking to see whether the new panel technology catches on in a competitive market, or trails behind less expensive alternatives. With Samsung expanding available models for the Wall, now in 75 and 219-inch sizes, and Apple is playing around with microLED technology for use in the Apple Watch, we here at TechRadar decided it was about time we dove into this technology to see what\u2019s going on.\u00a0 At this point, you might be wondering \u201cwhat about OLED?\u201d And, \u201cI just sold my house to buy an OLED TV, will my wife/husband/significant other be mad at me?\u201d \u00a0 Don\u2019t worry \u2013 it doesn\u2019t look like microLED is going to replace OLED any time soon, as it\u2019s still in the very early stages and nowhere near mass production. So, with all of the unfounded (at least for a while) fears out of the way, let\u2019s dissect what exactly microLED is, what it\u2019ll be used for, and whether or not it will one day replace OLED. Pictured: The Wall by Samsung, the world's first commercial microLED TVWhat is microLED?\u00a0 To put it simply, microLED takes traditional LEDs and shrinks them down to the microscopic level. Now, that might not seem all that impressive on first glance, but because of how small these LEDs are, and the fact that they\u2019re self-emitting, microLED is able to produce a picture with brightness that rivals OLED \u2013 without any of the downsides that come with using an organic substance.\u00a0 This means that you won\u2019t have to worry about a microLED display degrading over time. A microLED display, barring outside forces, will stay at its peak brightness with no natural degradation. You also won\u2019t have to worry about images burning into the screen, which will be a boon for anyone playing games, or even for smartphone and smartwatch manufacturers who would otherwise have to worry about UI elements reducing the lifespan of their devices.\u00a0 The only problem here is that it\u2019s currently extraordinarily difficult to manufacture any kind of screen using microLED \u2013 even for robots. For a standard 55-inch panel, you\u2019re looking at millions of microLEDs that need to be placed perfectly. Misalignment can lead to uneven lighting and colors, so until manufacturers can cross this hurdle, we likely won\u2019t see this technology in the mainstream. Not to be confused with QLED TV, Samsung's other premium panel technology, which you can see plenty of in the Samsung 2019 TV range.

In 2018, because the technology isn\u2019t quite there yet, it wouldn\u2019t make much sense to manufacture a TV using microLED technology \u2013 so OLED takes the win there, as it can literally be printed.\u00a0 There\u2019s also the issue of longevity. OLED, because it uses an organic compound that naturally decays over time, doesn\u2019t last forever. This is an issue, primarily because when you spend thousands of dollars on a high-end TV, you\u2019re doing so under the assumption that you\u2019re making an investment that will last a while. And, while you likely won\u2019t see any degradation within the first 5 years or so of using your device, it\u2019s not going to stay like that.\u00a0 That\u2019s not to mention the burn in. As gaming becomes more and more popular, with devices like the Nintendo Switch bringing in people who may have never played games before, burn in is going to start making a lot of headlines \u2013 especially as the price of OLED displays comes down. MicroLED doesn\u2019t have this problem. It\u2019s just a shame that microLED is so far away from being implemented into consumer televisions.\u00a0 However, it\u2019s a completely different story when it comes to mobile tech. Both Apple with its Apple Watch and Google with its rumored Google Glass comeback, are investing into microLED technology. And, it\u2019s here that microLED is going to shine within the next couple of years.\u00a0 That being said, however, don\u2019t expect the first generation of microLED wearables to be cheap \u2013 Apple is going to need to recoup the cost of research somehow.\u00a0 MicroLED not on your radar?

If you\u2019ve been paying attention, you might be sitting comfortably thinking that your OLED display is going to be future-proof, but we wouldn\u2019t be too sure.\u00a0 When it comes to the short term \u2013 over the next five years or so \u2013 OLED is probably going to stay the king of high-end TVs. This is mainly because of the cost involved with making panels in 2018. Sure, Samsung\u2019s The Wall was an awesome showcase of the technology, but that TV, when it eventually makes its way to market in August, will likely be something that only Elon Musk could afford. MicroLED simply won\u2019t be in a consumer device until its ready.\u00a0 Once the manufacturing technology catches up, and microLED panels don\u2019t cost a fortune to make, we think OLED is going to go the way of Plasma when LED took the market by storm.However, once the manufacturing technology catches up, and microLED panels don\u2019t cost a fortune to make, we think OLED is going to go the way of Plasma when LED took the market by storm. If consumers can buy a TV that\u2019s going to last longer, have the same picture quality \u2013 and they don\u2019t have to worry about leaving static images on the screen? It\u2019s pretty easy to see why that\u2019s an attractive offer.\u00a0 While microLED might not be taking over TVs anytime soon, the mobile phone market might be in for a shake-up.\u00a0 In 2017, the iPhone X made waves with its gorgeous OLED display, and we all know that the second it\u2019s viable, Apple is going to implement microLED into its iPhones \u2013 it\u2019s already investing in the technology. OLED was used first in phones as well, dating back to around 2005. We\u2019ll see microLED start off in mobile tech, and move into televisions sometime in the next 10 years \u2013 then it\u2019s all uphill from there.\u00a0 OLED or microLED, who's the winner? Look, we\u2019re not telling you to avoid buying an OLED display. In fact, OLED displays are behind some of the best 55-inch and 65-inch 4K TVs you can buy today. We likely won\u2019t see microLED make its way into consumer devices for a very long time, so holding off on a TV if you need one right now doesn\u2019t make much sense.\u00a0 However, we do think it's worthwhile to look towards the future to try and predict the tech that\u2019s going to be on our radar in the next decade \u2013 it\u2019s all in the name.\u00a0 We just can\u2019t wait to see what the future holds for microLED, and we would love nothing more than to get our hands on a TV powered by it.
