Difference Between LED and OLED

OLED (Organic LED) is solid state lighting (SSL) technology like LED. OLED is made of carbon-based thin organic layers that are compressed between two electrodes. LEDs are made of different types of heavy metals (arsenic, gallium, indium).

LED is an acronym created from the initials of the words Light Emitting Diode. OLED stands for Organic Light Emitting Diode.

As the name implies, the biggest difference between OLEDs and LEDs is the use of organic materials in OLEDs.

OLED (Organic LED) is solid state lighting (SSL) technology like LED.

OLED is made of carbon-based thin organic layers that are compressed between two electrodes. LEDs are made of different types of heavy metals (arsenic, gallium, indium). OLEDs are mostly made of organic materials, making them an environmentally friendly light source that can be easily recycled.

OLEDs are soft light sources scattered over a wide area. LEDs produce point and high intensity light.

OLEDs do not emit ultraviolet rays. LEDs produce a very limited amount of ultraviolet radiation.

The biggest reason for the interest in OLED technology is that they are flexible. OLED panels are thin like paper and can be bent in almost any way.

OLEDs produce less heat than LEDs. In this way, it eliminates the need for heat sink in product design.

OLEDs are much more expensive than LEDs. The price tag is the most important factor that prevents the spread of OLEDs.

OLEDs can reach an efficiency value of 100 lm/W, while LEDs can exceed 200 lm/W. This makes LEDs a more efficient light source.

While LEDs can offer up to 100,000 hours of life, OLED’s economic life is limited to 30,000-40,000 hours. In other words, LEDs have a longer life.

LED lighting is an affordable option for home users and is therefore widely used. OLED can really compete with LEDs as more companies invest in OLED technology. It would not be wrong to say that LED is the ideal choice for lighting projects.
