When it comes to color, QLED is excellent. 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. 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. When light hits them from the LED backlight, these dots emit their own light to enhance the image on-screen. 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 Samsung QN90A NEO QLED. This is the same tech, many iterations over, which Samsung introduced in 2015. QLED is a Samsung technology that builds on the typical LCD (liquid crystal display) television with LED backlighting.
In some cases, like with OLED, the black areas of the screen can go completely dark to give the picture more contrast and dynamic range. LED arrays with many points of light behind the screen now offer manufacturers more meticulous control over how each segment of the screen is lit. Some LED TVs use this edge-lit formation, others have moved on to more sophisticated setups. LED replaced CCFL (cold-cathode fluorescent lighting), which typically illuminated the screen from the edges.

QLED, OLED, and Mini-LED are all variations of this basic technology, which was used in electronic devices as early as the 1960s and became popular in TV technology thanks to refinement and eventual adoption by Samsung in 2007. LEDs are the small elements of a television screen that light up in order to produce an entire image on the screen.īasically, when an electrical signal runs through these cells, they emit light, and the television controls the electrical impulses in order to produce the image it wants to show. LED is an acronym for “light-emitting diode.” You likely interact with LED tech in some form multiple times per day, including the screen in your phone, light bulbs, and many other sources of illumination. So before you plunk down serious cash, make sure you’re getting the lighting style you want by understanding the differences in QLED vs.
It starts with the size and resolution, but there are competing backlight technologies to consider as well. So many choices when it comes to television.
