Samsung’s Three-Track TV Plan for 2018
May 14, 2018
 
Samsung announced three tracks for their 2018 TV plan. The first was the high end but ill named QLEDs. The second was the ill named micro-LED (really a mini-LED) TV with an LED array that would contain between 5,000 and 10,000 mini-LEDs rather than a set driven exclusively by self-emitting micro-LEDs.  A patterned RGB 4K display would have to be 24.8m LEDs for 4K, which, for a 65” TV would be ~21 LEDs/mm2.  While it is actually possible to produce LEDs of the size necessary, it is very hard to move them around, and it is also hard to maintain yields high enough to not have problems as even at a five 9’s yield, there would still be almost 250 dots on the screen that were not working, and while some have theorized that redundancy is the cure, replacing a bad LED by turning on the ‘extra’ one next to it, it just adds to the number of LEDs that need to be placed. The third track was an off-handed comment, which was, and we are not directly quoting, “I’m going to QOLED + OLED, but I’m just studying…” This leads us back to our report that Samsung Display is re-entering the OLED space, that could be a blue OLED, with a quantum dot red and green color converter or a directly printed RGB OLED side by side.
