Samsung, which originally developed OLED displays for smartphones, decided against it for TVs, instead pursuing quantum LED (QLED) tech. While its latest QLED models are better than ever, reviewers have generally found OLED tech from LG and Sony to be superior. As such, Samsung is working on MicroLED tech as a potential alternative to OLED.

MicroLED TVs, like OLEDs, have pixels that emit their own light, negating the need for a backlight. Both have high 10,000 to 1 contrast ratios and true blacks, while consuming less power than regular LEDs. However, Samsung claims that because MicroLEDs use inorganic materials, they'll last longer and suffer less from pixel burn-in than organic-based OLEDs.

Since the displays are constructed from a series of square MicroLED modules, they can be customized to any size you might want. However, when Engadget's Devindra Hardawar checked out The Wall at CES 2018, he noticed that the individual MicroLED panels were visible when viewed up close, forming a distracting checkerboard pattern on the screen. We'll soon see if that issue has been rectified for the production models, which should hit the market over the next few months.
