Abstract : Over the time there are many changes came into the field of output/display devices. In this field first came the small led displays which can show only the numeric contains.
Then came the heavy jumbo CRTs (Cathode Ray Tubes) which are used till now. But the main problem with CRT is they are very heavy & we couldn’t carry them from one place to another the result of this CRT is very nice & clear but they are very heavy & bulky & also required quiet large area then anything else.
Then came the very compact LCDs (Liquefied Crystal Displays). They are very lighter in weight as well as easy to carry from one place to the other.
But the main problem with the LCDs is we can get the perfect result in the some particular direction. If we see from any other direction it will not display the perfect display.
To over come this problems of CRTs & LCDs the scientist of Universal Laboratories, Florida, United States & Eastman Kodak Company both started their research work in that direction & the overcome of their efforts is the new generation of display technologies named OLED (Organic Light Emitting Diode) Technology.
In the flat panel display zone unlike traditional Liquid-Crystal DisplaysOLEDs are self luminous & do not required any kind of backlighting.
This eliminates the need for bulky & environmentally undesirable mercury lamps and yields a more thinner ,more compact display. Unlike other flat panel displays OLED has a wide viewing angle (upto 160 degrees),even in bright light.
Their low power consumption(only 2 to 10 volts) provides for maximum efficiency and helps minimize heat and electric interference in electronic devices.
Because of this combination of this features, OLED displays communicate more information in a more engaging way while adding less weight and taking up less space. Their application in numerous devices is not only a future possibility but a current reality.
