We break down the differences between the three main types of TV screen tech – and bring you some of the best models from each category.
A widespread practical application is using quantum dot enhancement film (QDEF) layer to improve the LED backlighting in LCD TVs.Light from a blue LED backlight is converted by QDs to relatively pure red and green, so that this combination of blue, green and red light incurs less blue-green crosstalk and light absorption in the color filters after the LCD screen, thereby increasing useful ...
Major technologies are CRT, LCD and its derivatives (Quantum dot display, LED backlit LCD, WLCD, OLCD), Plasma, and OLED and its derivatives (Transparent OLED, PMOLED, AMOLED). An emerging technology is Micro LED. Cancelled and now obsolete technologies are SED and FED.

Edge-LED lighting for LCDs allows thinner housing; the Sony BRAVIA KLV-40ZX1M is 1 cm thick, and others are also extremely thin. [citation needed] LED-backlit LCDs have longer life and better energy efficiency than plasma and CCFL LCD TVs. [35] Unlike CCFL backlights, LEDs do not use mercury in their manufacture, which is an environmental ...
The Omni QLED Series is available in 65- and 75-inch sizes; I reviewed the former. It's a handsome screen, with a barely-there silver bezel and tiniest of status-LED bars protruding from the ...
Quantum dot displays use blue-emitting LEDs rather than white LEDs as the light sources. The converting part of the emitted light is converted into pure green and red light by the corresponding color quantum dots placed in front of the blue LED or using a quantum dot infused diffuser sheet in the backlight optical stack.
