Samsung, which originally developed OLED displays for smartphones, opted instead for televisions and followed instead the technology of the quantum LED (QLED). While the latest QLED models are better than ever, critics have generally found OLED technology from LG and Sony superior. Therefore, Samsung is working on the MicroLED technology as a possible alternative to OLED.
MicroLED televisions, such as OLEDs, have pixels that emit their own light, eliminating the need for backlighting. Both have a contrast ratio of 1
Since the displays consist of a series of square MicroLED modules, they can be customized to any desired size. However, when Engadget's Devindra Himawar checked out the wall at CES 2018, he noticed that the individual MicroLED panels were visible when they were viewed up close, forming a distracting checkerboard pattern on the screen. We will soon see if this issue has been addressed for the production models that should be released in the next few months.
