I remember years ago, I saw a crazy 100-inch plasma TV at CES. It didn’t look great and it generated enough heat that I worried it would melt through the floor of the Las Vegas Convention Center and travel straight down to the earth’s core. In 2018, however, Samsung revealed a 146-inch, 4K TV it calls The Wall. It’s a concept at the moment, but it uses MicroLED lights that mimic the dark blacks and deep colors of OLED. Hooray for more TV backlight tech.
