micro LEDs- Are they the Future of displays?
We’ve got pretty used to the idea of incredibly high-resolution displays in tiny amounts of space. Just look at the cell phone in your pocket, probably packs in as many or possibly more pixels than the 60-inch TV in your living room. But the never-ending quest for higher and higher pixel densities stops for absolutely no one, which is why Apple has made headlines recently, for syncing a ton of money into making its own micro LEDs. But what are those and what’s the point when current mobile display tech seems to be serving us just fine?
Well, micro-LEDs bear resemblance to the organic LEDs that have become popular over the last few years. Unlike traditional LCD screens, each pixel on an OLED based display can generate its own light meaning that there is no need for a backlight that adds thickness and can wash the image out or make its colors look uneven. The result is an accurate clear picture with very deep blacks and contrast ratios that are marketed as infinite, not to mention a lower power draw which is key for battery-dependent mobile devices.
OLEDs are great but they’re kind of fatally flawed in a sense because the organic part of the OLED refers to carbon-based molecules that deteriorate over time, so the pixels themselves, especially, the ones displaying white can suffer from burning as some owners of OLED screens have found, if they spend lots of time playing games with static UI elements or watching the same TV channel with a logo in the bottom corner. microLED, by contrast, uses inorganic materials specifically Gallium Nitride(GaN) which not only lasts longer than the materials in OLED screens but it isn’t susceptible to burning, meaning that microLED offers the benefits of OLED without the common drawbacks and it can be made much brighter as well.
While using less power for the same brightness level, microLED screens are also more versatile. They are easier to manufacture in whatever sizes and shapes that you want. Samsung notably demonstrated this at CES 2018 with a 146-inch prototype television that it calls “The Wall” made up of smaller borderless micro LED panels. So in the future, we might finally break through the 65-inch barrier you know where TVs stopped getting bigger because they became impractical to transport home from the local best buy. I mean imagine this, instead of buying a whole new television set because of one patch of dead pixels, you could just go swap in a new modular panel and get on with your mindless consumption.
So because of all of these benefits, micro LEDs are interesting to more than just the traditional display manufacturers. So Apple reportedly has a team of engineers working on implementing them into its own devices but, they’ll probably be starting out with small, something like an Apple Watch being a prime candidate for a finished product with micro-LEDs.
A few years down the road although this sounds great, why wait so long?
The biggest drawback right now is manufacturing complexity. It takes a long time to put together a micro-LED display, as they have to be built one subpixel at a time. Think about how many of those there would be on a standard 4K TV. And so as is the case with a lot of cool sounding emerging technologies. We’re going to have to wait a bit before we’re all walking around with microLED gadgets in our pockets. But since Apple, Samsung, and LG all own multiple patents relating to micro LEDs it appears that the giants of the tech world are serious about releasing displays with pixels that don’t burn, assuming of course, that you have money that you can burn.
So that’s all for the micro-LEDs. Hope you get to know something new. If you liked this post, do visit newsbooklet.com which a lot of amazing content like this. Don’t forget to share your views on micro-LEDs in the comment section below.
