Organic Light Emitting Diode (OLED) displays will put the last nail in the coffin of LCD TVs.
OLED is a series of thin organic film between two conductors which which emit light when electricity passing across them. The main advantage of OLED is it produce light itself and no need of back lighting as in the case of LCD and TFT panels. Moreover these displays are more brighter, efficient , thinner and having good contrast ratio than LCDs. The prototype of big screen had been developed by many leading consumer electronics market players like Sony and Samsung but the main challenge of the technology transfer was the limited life of OLEDs, since these are made of organic materials. However the technological advancement
Advantages over LCD displays:
- Better contrast ratio
- Large viewing angle ( Viewing angle does not affect the quality, hue and brightness
- No need of back light hence power consumption is very low.
- Much thinner than LCDs and can be made flexible also.
- Very fast response time ie for LCDs approximately at the range of 2 ms and in case of OLED it is 0.01 ms) Expensive manufacturing process
- Poor life time
- Water and humidity can damage the display hence effective sealing is required.
Efforts are on to increase the life of OLED displays and new methods are being developed to reduce the production cost. Now LCD almost invaded the CRT market and the manufactures putting their maximum efforts to make it popular. An immediate shift to OLED may not be there because of the said disadvantages but if the technological advancement goes in the current pace then it will not take much more time. Remember the story of DVDs. How fast DVDs penetrated the market and invaded.
