This Really Is the Next Revolution in TV Technology
MicroLED is better looking, more efficient and more versatile than any previous display tech. Now all Samsung, Sony, LG and others have to do is figure out how to manufacture it affordably
LAS VEGAS—One of the most exciting things I’ve seen at this year’s CES tech show was a man putting a TV together. It looked more like he was hanging photos. He’d grab square tiles off a pile, attach them to the wall, then screw a small plate up top. A moment later, the surface would spring to life. He’d attach another, and it would extend the picture. He built a TV one tile at a time, and it looked awesome.
This particular set was a prototype of a new Samsung modular TV project. At CES, the company displayed screens as small as a magazine cover and as large as 219 inches—which it called, aptly enough, The Wall. Samsung’s goal is to let customers choose the exact size and shape of their own TV, assembled like Lego bricks.
You won’t be able to buy The Wall for a while—and even then it’ll likely only be affordable to people who already own several yachts—but in the meantime, Samsung intends to sell a 75-inch 4K TV based on the same technology. It’s called MicroLED, and it’s worth knowing about now, because it’s the biggest change coming to screens in a long time.
Painting the Picture
For years, LCD (aka liquid crystal display) has been the dominant TV tech. But LCD has a downside: Its pixels basically sit in a sheet of glass, and can’t be seen well unless there’s a big light—or many little lights—shining through it. Without the light, your TV would look more like an Amazon Kindle. Backlighting, though, means dark colors can only be so dark.

“MicroLEDs are the most interesting and exciting new display technology since the launch of OLED display products beginning in 2010,” said Ray Soneira, chief executive of DisplayMate, a display-technology research company.
Make It So
Samsung may have had the largest MicroLED display at CES—and may be hitting the market soonest with the first living-room-targeted set—but many other companies are working with the technology. TV giants LG and Sony have shown off MicroLED displays of their own. In 2014, Apple acquired a company called LuxVue that was also working on MicroLED displays.
In some ways, the tech may be even better for smaller screens like phones or smartwatches, or future devices like VR headsets and AR glasses. Your phone’s display accounts for a huge amount of its battery drain. Who wouldn’t want a screen that uses less power, looks better and can change its shape and size?
Your MicroLED TV is a long way off. “A very high proportion of displays using MicroLEDs will not happen in the next few years,” said Jamie Fox, an analyst with research firm IHS Markit . “It is still quite early in the progress of this technology.” As much as anything, it’s a manufacturing challenge: Your Samsung Wall would require careful placement of millions of tiny sub-pixels, each smaller than a human hair. That’s expensive, difficult and slow, three words nobody likes coming off the factory line.
Still, MicroLED is the display technology to watch in the coming years. When MicroLED manufacturing ramps up, and costs go down, the idea of dotting every surface with pixels won’t sound crazy. William Shakespeare famously wrote, “All the world’s a stage.” More likely, someday not too far off, all the world will be a screen.
