Difference Between LED and OLED

The main key difference between LED and OLED is that a wider viewing angle is noticed in the case of OLED. The black level is more dominant in OLED as compared to LED.  Here learn lot of difference between them, So here this article gives the main key difference between LED and OLED to better understand this topic.


Definition of LED

LED stands for light-emitting diode. In which it is a recombination of electron-hole pair that generates heat in the form of light energy. It works on the principle of electroluminescence.

Definition of OLED

OLED stands for the organic light-emitting diode. It is composed of organic semiconductor material thus termed as called as OLED. OLED is an advancement of LED,  while in  OLED is composed of organic semiconductor material.

The main key difference between LED and OLED

  • LED stand for light-emitting diode, while in OLED stands for the organic light-emitting diode
  • LED screen allows us to have this display as compared to LCD, OLED permits a thinner screen when we make its comparison with LED.
  • LED display provides a greater screen size of about 100 inches while in  OLED which is about 90 inches after the recent advancement.
  • The viewing angle of LED is 54 degrees, while in the viewing angle of OLED is 84 degrees.
  • 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 operations.
  • Screen burn-in is an issue related to CRT, plasma, and OLED as this effect it not marked in the LED display. Burn-in arises when the screen that is responsible for image formation degrades with time.
  • LED is more flexible, OLED is less flexible.
  • LED is a heavyweight, while in OLED lighter in Comparison to  LED 
  • The overall cost is less while using LED, but the cost is more while using OLED.
  •  LED display requires a backlight for its illumination, which is basically a light-emitting diode. As against the OLED does not need backlight in order to cause illumination as here carbon is used as an organic material that acts as a natural source of light.
  • Life span is more in LED, while in OLED lifespan is less.
  • Power consumptions more in LED, while in OLED power consumption is less.
  • Response time is slow in while using LED, while in OLED response time is fast.
