QLED vs OLED vs LED TVs Which one is the best?

When buying a new TV, the different technologies can be confusing. Marketing terms like OLED, QLED, and LED may all seem the same, but they actually refer to different panel types. Each technology offers different advantages and disadvantages to the picture quality.

LED and QLED TVs are similar to each other as they each use LCD panels with LED backlights. The only difference is that QLED TVs use a quantum dot layer that allows them to produce a wider range of colors.
OLED panels are completely different, as the pixels are self-lit and can turn themselves off when needed, allowing the TV to produce perfect blacks.

QLED is just a marketing term to signify that the TV uses a quantum dot layer.  LED TVs use the same backlight as QLEDs, but they don't have the quantum dot layer.

Picture quality between different OLED models doesn't differ much, as they each offer similar picture quality. However, picture quality can change a lot between QLED and LED models, and there are even different types of LED-backlit LCD panels that have unique characteristics.


LED, which stands for light emitting diode, emerged in the TV market before QLEDs and OLEDs. They use LEDs to light up an LCD panel. Many LED TVs have a VA panel, which normally has a high contrast ratio and narrow viewing angles, and they can get very bright.


QLED TVs use traditional LCD panels lit by LEDs. Between the LCD layer and the backlight, a quantum dot layer filters the light to produce more pure and saturated colors. QLED is a marketing term used by a few companies, like Samsung and TCL, on their quantum dot TVs.


OLED TVs can adjust the luminosity of each pixel individually. This allows them to turn them completely off to show pure blacks. This gives them exceptional picture quality, and they have wide viewing angles.

  • OLED stands for "organic light-emitting diode."
  • QLED (according to Samsung) stands for "quantum dot LED TV."
  • OLED is a fundamentally different technology from LCD, the major type of TV.
  • QLED is a variation of LED LCD, adding a quantum dot film to the LCD "sandwich."
  • OLED is "emissive," meaning the pixels emit their own light.
  • QLED, like LCD, is "transmissive" in its current form and relies on an LED backlight.
