What is differense between UHD TV and QLED TV?

Televisions come in all sizes, shapes, and with different kinds of features. If you wish to purchase one, it would be best if you knew the differences between each type so that you can make your choice according to your preference. In your search for the best kind of television to buy, you would most definitely come across two-panel technologies, which are UHD TVs and QLED TVs. UHD TV stands for Ultra High Definition television while QLED TV stands for Quantum dot Light Emitting Diode television. Both types of TVs have their separate features, some of which are similar and others which are dissimilar.

QLED TVs are unique to Samsung as it is the only brand that produces these TVs at the moment. These TVs have quantum dot filter, which is a film of tiny crystal semiconductor particles whose color output be controlled effectively. The quantum dots help to improve the television’s performance in areas of photo quality, and this results in very bright and Crystal clear pictures that have a wider and more accurate color.


Ultrahigh-definition televisions, on the other hand, include two digital video formats, namely, 4K UHD and 8K UHD. The horizontal screen resolution of the 4K UHD TV is 4000 pixels, whereas the horizontal screen resolution of the 8K UHD TV is 8000 pixels. What this means is that 4K UHD TVs have four times more pixels than regular high-definition televisions, while 8K UHD TVs have 16 times more pixels than regular high-definition TVs.

Although both TVs are similar in some ways, there still exist some differences between them. Such differences are:

  • Brightness levels: QLED TVs produce more vivid and brighter colors than UHD TVs. The result of this difference is a higher contrast ratio, with the picture that is provided by the QLED TVs being sharper than that offered by UHD TVs. QLED TVs generally have a high brightness level of 1000 nits, with some of them having up to 2000 nits brightness whereas, UHD TVs have a brightness level that does not exceed 500 to 700 nits.
  • Motion blur: For UHD TVs, particularly 4K UHD TVs, moving pictures can blur to an extent because the pixels through which they shift changes from one color to another. The speed at which these pixels change color, also known as the response time, determines if the picture produced would be blurred or not. This speed is particularly apparent in fast motion pictures. Lower response times mean that they will be lower motion blur whereas, higher response time would produce a more blurred image. QLED TVs, on the other hand, are much better at handling color changes and have a very low response time.
  • Color performance: Color performance in these two TVs is quite similar. However, QLED TVs offer a little higher color level performance than UHD TVs.

Although both types of televisions have great features, QLED TVs seem to have better features than UHD TVs. However, they are more expensive than UHD TVs. You can make a selection depending on what you can afford and what specifications you require.
