Which technology is Better for a LED TV


The advent of the first Samsung Quantum dot LED TV in the market started the hot debate of which technology is better: QLED or OLED. To understand both the technologies, we have to delve deep into their working and constituents to make a clear distinction. Furthermore, we have to navigate through the watching experience of the customers to understand which LED TV system is better relating different parameters. This article illuminates the difference between OLED and QLED and gives a verdict about which LED TV can be a perfect choice for you. Let us look at each technology.


OLED or Organic LED TV has a display tech that constitutes carbon-based organic films. Light comes out when two conductors pass an electric current through the film. 

  • Pros: 
    • Perfect blacks. Unlike the LED TV display technology, in OLED panels, individual pixels produce light. Thus when portraying darkness, the screen pixels do not light up all at once, projecting a perfect black picture experience.
    • Near-ideal viewing angle: OLED televisions have a viewing angle of up to 170 degrees which transforms to 85 degrees on either side from the centre, giving colour-richness and crispiness to the pictures.
    • Quicker response time: OLED TVs reduce response time compared to LED TV resulting in less motion blur.
  • Cons: 
    • Screen burn-in: Burn-in cases result in OLED TVs from static images displayed continuously on the screen for several hours at a stretch.


QLED or Quantum dot LED TV technology entails placing a coating of quantum dots in front of a regular LED backlight panel. QLED’s are not self-emissive, unlike the OLED display. QLED panels are capable of producing billion of different shades of colour in a TCL TV.

  • Pros: 
    • Brightness levels: Quantum LED TV sets can produce lifelike and bright images on the screen.
    • No Screen burn-in: Unlike OLED, the Quantum dot LED TV models do not exhibit screen burn-in, thanks to the inorganic nature of LED panels.
  • Cons: 
    • Backlight bleed: The problem of backlight bleeding arises when the backlight around the edges or the corner of the TV display starts leaking. QLED TVs is prone to this issue gamers mostly face. 

Now, let us examine the different factors determining which screen tech is better. 

Determining Factors for an optimal viewing experience

  • Black Level: QLED gives out a pretty good black level, while in OLED, you can experience perfect blacks.
  • Motion Blur: QLED offers better motion blur than an LED TV, where OLED brings near-perfect motion Blur.
  • Viewing Angle: Even the Quantum dot tech fails to improve the poor viewing angle of an LED TV. On the other hand, OLED bestows a superior viewing angle. 
  • Colour Volume: The greatest advantage of the Quantum coat on the LED backlights is the rich colour volume. OLED can not produce as vibrant colour volumes.
  • Grey Uniformity: This is a no-brainer that OLED produces better grey uniformity than the average quality greys of a Quantum dot LED TV screen.
  • Luminosity: When it comes to luminosity, OLED falls behind the greatness of the Quantum dot LED TV.
  • Image Retention: QLED also beats OLED with its inbuilt capability for better image retention.

Final thoughts

It will take some time to accomplish the visionary MicroLED and the self-emissive quantum dot technology. Until then, most TV buyers have to choose which combination of strengths and compromises best suit their taste. Want better colour volume? Go for QLED. Want a near-ideal viewing angle? OLED is your best choice.

No matter which TV you buy, affordability is always of concern. Using the Bajaj Finserv EMI Network Card, you can purchase your desired TV  with a no-cost EMI repayable over a tenor of 24 months while enjoying other perks like cashback and offers.

Summary:While in this golden age of LED TV technology, 4K and 8K TVs are becoming very common, it also gets utterly confusing for the layman to understand the tech jargon. While each technology comes with its own strength and weaknesses, it becomes a responsibility for anyone to choose a suitable LED TV prudently. If you aspire to bring superior picture quality to your living room, you need to choose between a QLED or an OLED TV. This article comprehensively discusses the merits and demerits of both technology while giving a clear direction to forming a sound buying decision.
