Local dimming improves this issue, but it's not 1:1. Not all the light can be blocked, so the image is grayer and has less "punch" than with OLED. The liquid crystal panel that creates the image only blocks the light created by the backlight. With LCD, though, it's much harder to do. This is, for example, how OLED and MicroLED work. Ideally, you'd be able to dim each pixel enough to create a visually impressive contrast ratio. For more on this, check out LED local dimming explained.

This is where the TV dims the LEDs behind dark sections of the image to create a better contrast ratio between the bright parts of the image and the dark.
For improved image quality, particularly to appreciate high dynamic range (HDR), you need local dimming. On others, the LEDs are behind the screen, pointing toward you. In some TVs the LEDs are on the edges, pointing inward. In your TV these LEDs are collectively referred to as the "backlight." They range in size - commonly they're around 1 millimeter, but can be smaller than 0.2 millimeter. These tiny devices emit light when you give them electricity and are being used everywhere in the modern world, from the flashlight on your phone to the taillights on your car. every TV that's not an OLED), there's anywhere between a few, to a few hundred light emitting diodes. To understand mini-LED, you need to understand standard LED, at least as far as your TV is concerned. Light-emitting diode TV technologies comparedīright lights, big TV, better local dimming Here's how the two stack up against one another as well as standard LED, QLED and OLED. MicroLED isn't LCD at all, it's a whole new TV technology that also happens to use LEDs. A liquid crystal layer, the LCD itself, modulates that light to create the image. Just like the standard LEDs found in current TVs, they're used to power the backlight of the television. Mini-LEDs are found inside normal-size TVs but the LEDs themselves are much larger than MicroLEDs. MicroLED is seen here in a massive 219-inch size Samsung calls The Wall.

And while each individual MicroLED is tiny, the modular nature of MicroLED means it can get truly gigantic.
Essentially, you're looking directly at the LEDs that are creating the picture. MicroLED displays from Samsung and LG use millions of LEDs, one for each pixel. Mini-LED is currently available in TVs as small as 55 inches and as affordable as $700.
MicroLED is a near-future tech that's reserved for huge screens and rich people today - like a 110-inch Samsung for the cool price of $156,000. Here's how it works, and why it's so cool.īefore we get started, know that mini-LED and MicroLED are not the same thing. Now that just about every TV maker will sell a mini-LED TV of some kind in 2022, you're bound to hear a lot more about the technology. In the mini-LED TVs we've tested so far, including the TCL 6-Series and Samsung QN90A, the picture quality improvements are the real deal, although not quite good enough to beat OLED. Mini-LED is an evolutionary technology, not a revolutionary one, and draws on existing LCD TV technology. Mini-LED's main advantage over OLED, the best TV tech on the market, is that it can be more affordable, particularly in larger screen sizes. By using more, smaller LEDs to illuminate the screen, a TV can have finer control over its highlights and shadows, for potentially better contrast and image quality especially with HDR shows, movies and games. Let's start with what makes mini-LED special. Samsung calls its version Neo QLED, LG is going with QNED for some reason while the latest version from TCL is called OD Zero.
TCL, Samsung and LG all introduced new mini-LED TVs and Sony and Hisense will ship their first mini-LED TVs later this year. It's an evolution of traditional LCD TV tech that uses thousands of tiny light emitting diodes to improve picture quality, and at CES 2022 more TV makers than ever are using it. TVs get a bit better every year, and in 2022 the improvement with the biggest impact might be mini-LED.
