Difference Between LED and QLED

A similar word is being confused by the people, and they considered both the items are the same. People often considered both LEDs and QLED is the same; there is no difference between them.

LED vs QLED

The difference between LED and QLED is that the LED stands for light-emitting diodes. On the other hand, QLED stands for Quantum dot light-emitting diodes.

LED vs QLED

LED also stands for light-emitting diodes. It is also a type of LCD TV that uses light-emitting diodes. Led tv backlight the display rather than using cold cathode fluorescent lights, which are used in an LCD television.

QLED stands for Quantum dot LED television. Quantum dot is actually a display device that uses semiconductor nanocrystals and quantum dots to make pure monochromatic green, blue, red lights.

Brightness level LEDs deliver more brightness in the picture without consuming more power.QLED was not able to deliver a minimum brightness level without consuming more power.
Contrast level LEDs can deliver sharper and rich color along with great dynamic contrast, and it also delivers the wider color along with greater light intensity.QLED also delivers more excellent contrast and bright white and true black colors, as in QLED, each pixel has its lights.
Technology LED uses the technology just like the LCD television, which has light-emitting diodes to backlight the display rather than cold cathode fluorescent lightsQLED uses quantum dot technology to release the light.

 

What is an LED?

The word LED stands for light-emitting diode. It is also referred to as small, efficient light, which releases the light when the electric current is passed. It is very much different from CCFL backlit LCD TV in every way.

The leading technology behind the development of LED is actually back in from 1960. At that time some scientist was working on the chip of semiconductor material that soaks the impurities to a create-n junction or positive-negative junction.

It is used to believe that different techniques have been used. Three most commonly used in the edge-lit LED are white LEDs that are placed around the edge of the screen, which also spread the panel so that it lights the display.

What is QLED?

The word QLED stands for quantum dots light-emitting diode. This television is treated as the modern generation television display, which is promoted by Samsung for the excellent newer and advanced LED television.

As the term, this technology uses quantum dot technology to release the light by giving an extra layer of tiny particles before a regular LED backlight panel, which shows a better result in rich colors, dynamic contrast, color accuracy, and peak brightness.

Main Differences Between LED and QLED

  1. LED televisions consume less power and deliver maximum brightness levels. On the other hand, QLED was not able to deliver minimum brightness without consuming more power.
  2. LED television uses technology, just like LCD television. On the other hand, QLED television uses Quantum dot technology.
