What QLED and OLED TVs Have in Common

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

What a QLED TV is
6
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.
