Advantage of QLED TVs over OLED TVs

By Vinay Prakash on: 19-05-2017

Recently Samsung has launched QLED (Quantum dot light emitting diodes) TVs. QLED technology is the latest technology for the display screen. QLED is considered as a next generation display technology after OLED-Displays. Really it is great news for TV technology and those who looking for the best viewing experience at home. In recent past OLED (Organic light emitting diodes) technology for display was best but QLED technology has few advantages over OLED. That's why manufacturer prefers QLED technology for manufacturing large screen display with batter better colour gamut. QLED is very similar to the OLED technology. But the difference is that the light emitting. Light emitted by QLED is pure in colour because new QLED TVs have a peak luminance. All QLED TVs will use edge-lit local dimming.

Here I am not going to discuss the Specification and special feature of Samsung QLED TV but going to focus on Why move from an OLED to QLED?. Of course, latest innovations have few advance features than past. QLED technology is latest and it has few advantages over OLED technology.

QLEDs advantages:

  • The rich colour volume (100%)
  • QLED picture-quality has higher light output and a better colour for HDR sources. It means both the light output and colour volume advantages only apply to HDR (high dynamic range) material.
  • Luminance efficiency (30-40%) of QLED is better than OLED at the same colour point.
  • Low power consumption makes QLED more efficient more than twice as power efficient as OLED at the same colour point.
  • QLED Technology has potential to manufacture large size display on ultra-thin flexible substrates with low manufacturing cost.
  • The QLED display is Ultrathin, transparent and more flexible.
  • QLED TVs have a peak luminance of between 1,500 and 2,000 nits (a nit is a unit of visible-light intensity, commonly used to specify the brightness of a display).
  • Ultra black technology absorbed light for lower reflective and deeper black.
  • Improved the LED back-lighting.

LED backlighting

light from a blue LED is converted by Quantum dots to relatively pure red and green, so that this combination of blue, green and red light incurs less absorption of unwanted colours by the colour filters behind the screen, thereby increasing useful light throughput and providing a better colour gamut.

There are two types of LED backlighting.

  1. LED backlighting (full array)-Behind the screen, whose brightness is not controlled individually.
  2. Dynamic local dimming backlight-LEDs controlled individually (or in clusters) to control the level of light/colour intensity in a given part of the screen.


If u want to enjoy the best experience of a large screen with pure colour and brightness which give your eye relax while you watching the TV. QLED Technology is one of the latest innovations for next generation TVs. But price of QLED TVs will be few higher than OLED TVs.
