The terms "OLED" and "QLED" refer to two display technologies used in televisions. Here are the main differences between the two:

Display technology:

  • OLED (Organic Light-Emitting Diode): OLED TVs use organic light-emitting diodes to produce light and display images. Each pixel in an OLED display is able to emit its own light and turn off completely, resulting in deep blacks and high contrast.
  • QLED (Quantum Dot Light-Emitting Diode): QLED TVs use quantum dots to improve color accuracy and brightness. Quantum dots are nanocrystals that convert the light emitted by an LED backlight source into more accurate and vivid colors.

  • Contrast and blacks:

  • OLED: OLED screens offer extremely high contrast because individual pixels can turn off, producing perfect blacks. This gives a better viewing experience in dark scenes.
  • QLED: Although QLED TVs offer deep blacks, they cannot match the absolute contrast level of OLED screens due to their LED backlights.

  • Brightness and HDR:

  • OLED: OLED screens are generally less bright than QLED screens, although brightness continues to improve with advances in technology. OLED TVs support HDR (High Dynamic Range) formats for better brightness and color range.
  • QLED: QLED TVs are generally brighter than OLED screens, making them suitable for bright environments. They offer better peak brightness for HDR content.

  • Angle of vision :
  • OLED: OLED screens have an excellent viewing angle, which means that colors and contrast generally remain consistent, even if you're looking at the screen from a side angle.
  • QLED: Although QLED TVs also have a good viewing angle, some models may exhibit a decrease in color quality and contrast when viewed from a side angle.
  • Sustainability :
  • OLED: OLED screens are more likely to present a screen burn hazard, particularly if a static image is displayed for long periods of time. However, OLED technologies have seen improvements to reduce this problem.
  • QLED: QLED TVs are generally more durable in terms of risk of screen burn-in because they use LED backlighting rather than organic diodes.

  • Ultimately, the choice between OLED and QLED comes down to your personal picture preferences.
