What QLED and OLED TVs Have in Common
                     QLED versus OLED: Is One 
Really    Better Than the 
Other?

What QLED and OLED TVs Have in Common
1. The showcase goals (1080p, 4K, 8K) for a particular model of QLED or OLED TV is controlled 
by the producer. 
2. On the off chance that HDR is incorporated, explicit HDR design similarity is dictated by the 
maker. 
3. In the event that good with savvy TV innovation, the actualized stage on a particular model is 
dictated by the maker. 
4. The two of them can be stand-or divider mounted. 
5. Both can be planned with a level or bended screen as dictated by the maker.

What a QLED TV is
At its center, a QLED TV is a LCD TV. Be that as it may, QLED 
TVs utilize two extra advancements that are planned to 
improve picture quality. 
1. Driven back or edge light gives the light source that goes through 
the LCD chips to deliver a picture (LED/LCD TV). 
2. A layer (sheet) made out of Quantum Dots (that is the place the Q 
originates from) is set between the backdrop illumination and 
LCD layer.
What Quantum Dots Are
When Quantum Dots are hit with a light source (in the case of an LCD TV a Blue 
LED back or edge light), each dot emits a color of a specific bandwidth, which is 
determined by its size. Larger dots emit light that is skewed towards red, and 
progressively smaller dots emit light that is skewed more towards green.
The most common method of incorporating Quantum Dots into LCD TVs 
(Samsung, TCL, and Vizio are examples) is by placing the dots on a sheet of 
"Quantum Dot Enhancement Film" (QDEF) that is placed between a Blue LED 
backlight and the LCD panel.

A Blue LED backlight and the light emitted from the Quantum Dots 
passes through other layers, such as polarizers, color filters, and LCD 
chips and onto the screen for image display. The added Quantum Dot 
layer enables the QLED TV to display a more saturated and wider 
color gamut (range) than LCD or LED/LCD TVs without the added 
Quantum Dot layer.

What You Need to Know When Shopping for a QLED TV
1. QLED TVs are offered in screen sizes extending from 43 to 85-inches. 
2. QLED TVs are exceptionally brilliant. Contingent upon brand and model, light 
yield can reach as much as 2,000 nits. 
3. QLED TVs give more shading volume than non-QLED TVs. This implies you don't 
lose shading immersion and exactness as brilliance increments. 
4. QLED screen consistency (the equity of high contrast over the screen) fluctuates 
by the brand/model with the quantity of LED darkening zones.
Who Makes QLED TVs
Samsung is the primary maker of QLED (Quantum Dot) TVs, 
followed by Vizio for the U.S. market. TCL offers QLED TVs in the 
Asian and other select international markets. 
Samsung has used the terms SUHD/Nanocrystal (2016), 
Quantum Dot (2017), and QLED (2018/19) for TVs that 
incorporate Quantum Dots.
