![]() ![]() ![]() QLED, or quantum dot LED, uses nano-particles that have a special property: When light shines on them, they can emit their own light, specifically tuned to a certain color. Where does QLED fit into all of this? TCL So far, we haven’t seen a mini-LED TV that gets as perfectly black (and without any blooming) as OLED, but that gap between backlit TVs and emissive displays such as OLED TVs is smaller than it has ever been. This not only makes the darker portions of the screen darker, but the contrast created makes the lighter portions seem even brighter. With mini-LEDs, local dimming becomes far more effective because it increases the number of dimmable zones while decreasing their size, making it easier to isolate dark areas from light ones. But even with FALD, if there’s a big difference between the brightest part of the screen and the darkest, it can lead to blooming - an effect that makes it look like light is leaking from the bright portion into the darker portion. To achieve a deep, dark black in a specific portion of the screen on a backlit TV - the kind you expect when looking at space scenes - you need to shut off the backlight in that portion entirely. It’s all about the light (and the dark) Image used with permission by copyright holderĪs we said earlier, more LEDs lead to better brightness - beneficial for HDR as well as making the picture visible in bright rooms - but it also leads to better darkness, too. We’re talking about being able to fit thousands of LEDs in a space that once could support only hundreds.Ī 4K TV has just over 8 million pixels, so mini-LEDs are still significantly bigger than an individual pixel, but that’s OK: Mini-LEDs are so much smaller than standard LEDs that you can still see a big difference. It breaks through the previous size barrier by introducing LEDs that are much smaller than any that have been used so far. This size-based constraint on the number of possible LEDs is what makes mini-LED technology so exciting. ![]() The bigger they are, the fewer you can use. There’s a physical limit to the number of regular LEDs you can squeeze into a given space, which is determined by the size of the LEDs themselves. In a perfect world, you’d have one LED for every pixel in an LCD matrix, but right now, that’s impossible. has supplied the FBI, Homeland Security, Law Enforcement Agencies around the world and hard working people like you.The best OLED TVs for 2023: from LG, Sony, and Samsungīest TV deals: cheap TVs worth buying from $88īest 65-inch TV deals: 4K, QLED and OLED TVs on sale Our special long wave 365 nm black lights are used for inspections, finding cracks and leaks, UV Curing of adhesives and resin, just about anything.
