OLED – Big brother of LED

CRT, TFT, Plasma, LCD, LED….. yes I know that you all know about these concepts. So ready for something new from this species.. Ok then take a spin and meet organic light emitting diode (OLED).

Some gyan about OLED: An organic light emitting diode (OLED), also light emitting polymer (LEP) and organic electro luminescence (OEL), is any light emitting diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. The layer usually contains a polymer substance that allows suitable organic compounds to be deposited. They are deposited in rows and columns onto a flat carrier by a simple “printing” process. The resulting matrix of pixels can emit light of different colors.

 Sounds cryptic…. Let me ease you 🙂: OLED (Organic Light Emitting Diodes) is a flat display technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. Because OLEDs produce (emit) light they do not require a backlight.

This means that OLEDs can be made very thin and very power efficient when compared to LCD (which do require a white backlight).

Dont Believe!!! take a look: OLEDs vs LCDs

  • Low power consumption – OLEDs are a far better choice for portable devices. It also makes OLEDs much more environmental friendly, and a candidate to be the white-light “bulb” of the future.
  • Faster refresh rate and better contrast.
  • Greater brightness – The screens are brighter, and have a fuller viewing angle.
  • Exciting displays – new types of displays, that we do not have today, like ultra-thin, flexible or transparent displays.
  • Better durability – OLEDs are very durable and can operate in a broader temperature range
  • Lighter weight – the screen can be made very thin, and can even be ‘printed’ on flexible surfaces.

Sony has been working OLED and Sony’s OLED (Organic Light Emitting Diode) TV, the XEL-1, is truly the next big thing in television technology. It has a contrast ratio of 1,000,000:1.

  1. Write more, thats all I have to say. Literally, it seems as though you relied
    on the video to make your point. You clearly know what youre talking
    about, why throw away your intelligence on just
    posting videos to your weblog when you could be giving
    us something informative to read?
