• LED replaced CCFL (cold-cathode fluorescent lighting) as backlighting

• Quantum Dots produces their own light when hit by LED backlight

The goal is to lessen one of the main weaknesses of LED technology, which is the “blooming” effect of brighter parts of an image slightly lighting the areas around the image, and color bleeding.

  While QLED offers some improvement over traditional LED, it doesn’t always mitigate this blooming and the contrasts between light and dark are not as stark as with some other technologies.

  What about color?

  When it comes to color, QLED is excellent. There is a tremendous amount of color variety available in QLED screens, with good color contrasts. QLED also tends to be cheaper at larger sizes than other backlighting techs, meaning that QLED is the best budget-conscious choice when it comes to a new higher-end TV. QLED also tends to result in screens that can reach a higher level of overall brightness, which may be desirable depending on your screen needs.

  If you want to experience this type of screen, a strong budget 4K UHD option is Samsung’s 43-inch TU-8000 series from 2020. This Samsung QLED TV is a very cost-conscious choice that delivers 4K and is great for a dorm room, a child’s room, or as a second/third display. At only $379.99 MSRP, it’s about as cheap as you want to go. But if you’re looking to build a home theater set-up, or care about getting the best picture quality and options, this is not the television for you. QLED TVs can climb into the higher-end, and you can check out our recommendations for some of the best QLED TVs, but they face stiff competition from OLED and now Mini-LED.

  Samsung introduced QLED in 2015. The Q in QLED stands for “Quantum Dot.” They are embedded directly into the stack of materials that make up the LCD display, such as in the flagship 

• Mini-LED is similar to QLED, but the backlights get even smaller

  Mini-LED represents the halfway point between QLED and OLED, taking the older tech and trying to approximate what the newer tech can do. Mini-LED offers noticeably better than QLED or typical LCD and it may be hard to discern a difference between the contrast on Mini-LED and OLED, as the Mini-LED diodes can get almost to the pixel level. The deep blacks that OLED promises are essentially available with Mini-LED.

  You won’t be able to get the same pixel-level control over black levels as you would with OLED, but some Mini-LED TVs promise up to 3,000 backlight zones. It’s likely this difference is barely noticeable to the average consumer. Mini-LED scales to cost at a more expensive clip than QLED, and is essentially the “premium” version of that same base technology, at least for now until it becomes more widespread.

  These LEDs are so small they can be almost as small as a single pixel. QLEDs are significantly larger than one pixel, while OLEDs are the size of a single pixel.

• miniaturizes LED technology even further

• OLED is an umbrella term for any display using organic light-emitting diodes
• produces its own light and does not require a backlight
• the light can be controlled on a pixel-by-pixel basis
• best display that shows true black color
• conserves power when displaying black images
• slimmer
• dissipate less heat
• posses better contrast ratio than LCD
• shorter lifespan

  LCD TVs rely on a backlight to shine through a stack of display materials to create an image. This puts them in a category called transmissive screens. OLEDs, however, are different. OLED screens consist of many tiny diodes that emit their own light, which lands them in a category called emissive displays. When an OLED display wants an area of the screen to show black, it simply turns off the pixels in that area, which creates much darker tones without concern for light bleeding through from brighter surrounding areas.

  When it comes to color, OLED can have some lifespan issues. While red and green OLED pixels have a pretty long lifespan (over 45,000 hours), blue OLED pixels tend to have one-third of that lifespan. This means that long-term, an OLED display may have issues with color accuracy as the blues start to die off. Displays inside businesses experience this even more often than sets in homes. Of course, for the average home user, the 15,000-hour lifespan of a blue OLED pixel may never become an issue.

  OLED is “organic” LED. An OLED consists of organic materials that produce similar effects when current runs through them. But OLED displays work fundamentally differently than typical LED-lit LCDs.

• uses an extra white sub-pixel to increase brightness and improve longevity compared to traditional RGB OLEDs
• uses color filters
• white source emitter + RGB filter = better brightness + good color gamut

• combines the best of QD and OLED
• emits a blue light
• instead of color filters, it uses quantum dots
• blue source emitter + GB re-emitters = better brightness + greater color gamut

• a type of advanced OLED display technology developed by LG Display to improve brightness and efficiency

an advanced type of OLED that uses “Active Matrix” technology attached to a thin-film transistor (TFT) to exert more control over each pixel.
