![]() Samsung established the QLED Alliance in partnership with Hisense and TCL for the purpose of promoting the QLED term to TV buyers, but so far, these three companies remain the only ones that use it in their marketing. Samsung helped to popularize quantum dot technology, and it established the QLED trademark, but most TV makers have quantum dot-based TV models these days. This benefits standard dynamic range (SDR) material, but it’s especially helpful when displaying high-dynamic range ( HDR) video, which relies on high brightness and contrast. This gives an LED TV the ability to display more colors with greater accuracy and (if the LED backlight is sufficiently powerful) incredible brightness. This gives the color filter the starting point it needs, and because of the efficiency of quantum dots, almost no brightness is lost in the process. When the blue light from the LEDs combines with the red and green light emitted from the quantum dots, you get a very pure, full-spectrum white light. The quantum dots absorb the blue light from the LEDs and convert it into red and green light. So QLED TVs swap out white LEDs for blue LEDs and then layer red- and green-tuned quantum dots on top. The light they emit can be tuned to specific portions of the color spectrum. These quantum dots are tiny phosphorescent crystals that possess an almost magical quality: When they’re exposed to light, they emit their own light with a very high level of efficiency. ![]() QLED solves this problem by adding a layer of quantum dots to a TV’s LED backlight (thus the Q in QLED).
