Oraganic LED Light Bulbs

OLED, stands for organic light-emitting diode, which is another form of LED (Light Emitting Diode) where the light is produced from a layer of oranic compounds. The layer is usually made up of ploymer substance and oraganic compound is arranged in rows and columns on the layer. Such an arrangement allows producing light in different colors.

OLED technology was first developed at Eastman Kodak Company using small molecules. The initially developed technology resulted in expensive production of OLEDs and since it used glass based material, it was not flexible either.

The current technology that's used to manufacture OLEDs has brought down the costs associated with producing them.

Advanatges of OLEDs over other Light Emitting Diodes

  1. OLEDs can be printed on either flat or flexiable surfaces.
  2. An inkjet printer or any other suitable screen printing technology can be used to print OLEDs on a surface.
  3. OLEDs based display products can be much much cheaper than LCD (Liquid Crystal Display) and Plasma displays.
  4. OLEDs can be printed on paper and even clothes. You could even print it on a sheet and paste it on the wall.
  5. OLEDs consume less power than LCD and have very low response time of 0.01ms when compared to the response time of LCDs which is between 8-10ms.
  6. OLEDs based displays can be viewed from various angles but the same can not be done with LCDs.

Disadvantages of OLEDs

  1. The lifetime of traditional OLEDs is around 15,000 hours when compared to LEDs whose lifetime is around 50,000 hours. This is majorly due to the oragnic material used to produce OLEDs.
  2. OLEDs are very sensitive to water and heat. Normal wear and tear can also cause damage to OLEDs.

Applications and uses of OLEDs

OLEDs are used by vast majority of industries in numerous products that they manufacture. The following are some of the practical uses of OLED technology that includes commercial products also.

  1. Screens of Mobile phones
  2. Screens of portable MP3 players
  3. Audio players in cars
  4. Television screens (Sony was the first company to announce OLED television in Oct 2007)
