  1. LED display requires a backlight for its illumination, that is basically a light emitting diode. As against, OLED does not need a backlight in order to cause illumination as here carbon is used as an organic material that acts as a natural source of light.
  2. An OLED display provides a better viewing angle of about 84 degrees as compared to LED which is about 54 degrees.As LED display provides excellent picture quality when viewed from the centre and deterioration in picture quality is noticed in it when we move either side of the centre.
  3. When we talk about brightness level then LED display provides much better brightness in comparison to OLED. At the same time by making use of quantum dots, that boosts the quality of backlight, the brightness of LED shows a considerable increase.However, forcing an OLED to provide its maximum brightness for a longer duration can reduce its lifespan.
  4. LED screen allows us to have a thin display as compared to LCD. But, OLED permits a thinner screen when we make its comparison with LED.
  5. LED provides a slower response time than that of OLED. As the diodes inside an OLED system responds at a much faster rate in comparison to the diodes in LED.
  6. LED display provides a greater screen size of about 100 inches in comparison to OLED which is about 90 inches after the recent advancement.
  7. OLED consumes less energy for its operation as compared to LED due to its self-illuminating property as it does not need a backlight to initiate the operation.
  8. Screen burn-in is an issue related to CRT, plasma and OLED as this effect is not marked in the LED display. Burn- in arises when the screen that is responsible for image formation degrades with time.
