An organic light emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current. This layer of organic semiconductor material is situated between two electrodes. Generally, at least one of these electrodes is transparent.

Please tell me the same and the difference between LED TV and OLED TV.?
There are a lot of similarities to be had between the LED TV and the OLED TV. Both the LED TV and the OLED television feature some of the best contrast levels in the TV market. They both have deeper blacks than other televisions. This means that the black comes across as darker, and contrasts more with the other colors. This helps these other colors to stand out more. Both types of TVs are also thin, and are generally thinner than other types of TVs, including LCD TVs. There are a few major differences between the two types of televisions. The main differences focuses around the backlight. The LED TV is actually an LED backlit LCD TV, utilizing LEDs for the perfect backlighting. OLED TVs, on the other hand, do not need a backlight to operate. The LED technology is relatively old when compared to OLED technology. OLED TVs are newer, and are using the most recent form of LED technology. With LED technology, the lights are bright white and are forced through a color filter. With OLED TVs, each LED is actually creating the color that is needed. This is what creates the more dynamic picture, giving OLED TVs a nicer picture than LED TVs.
How does an OLED screen differ from a normal LED screen?
Put simply, a standard LED screen is essentially a lamp made from light-emitting diodes, whilst the OLED screen is made from millions of small LED's, the 'O' stands for 'organic'.
What is the difference between LGs OLED TV and other company OLED TV there was news about LG introducing an OLED TV which is different from other brands of OLED TV Can someone tell me the detail?
LG's OLED TV uses four base colors White, Red, Green, and Blue through a color filter. Other types of OLED uses only 3 base colors that are tuned to provide a full range of colors without the need for a fourth sub-pixel.
How much of energy can be saved by watching oled tv instead of watching led-lcd tv?
OLED TV actually consumes much less power comparing to any other LCD or LED TVs. It's like OLED consumes almost 70% less power than LCD TV, but there are already some energy saving LED TVs in the market. Even so, OLED TVs are a lot more energy efficient, consuming about 40% less power than any latest LED TVs. That is again one of the strong points of OLED TV.
How much price will fluctuate in between white oled tv and standard oled tv?
The actual price hasn't been disclosed by any of the brands who unveiled their OLED TVs.
What is the difference between true-oled and woled-cf?
The basic OLED TV design (called a "True-OLED" TV) uses 3 color OLED sub-pixels (Red, Green and Blue) to create each 'pixel'. But some companies are using a different archicture, called WOLED-CF which uses four white OLED subpixels with color filters on top (RBG and W). This is also called a RGBW design. The WOLED-CF technology was developed by Kodak (and the IP is now owned by LG Display), and it should make the OLED panel easier to make. However it will also be less efficient. LG Display's OLED TVs which will be released in 2012 will be based on this design.
What is the difference between and LCD and LED Television?
LED televisions are currently LCD televisions with LEDs used as back lighting. They use the same display technology as other LCD televisions but have replaced the CCFL lighting. There is a new breed of LED television about to be launched. Organic LEDs known as OLED are being developed for a true LED display. Unlike LCD which uses a light behind liquid crystal shutters, OLED televisions use red, green and blue LEDs at each pixel location to generate the color and intensity of the pixel. OLED televisions are promising to be slimmer than ever before and are likely to reduce build costs in the future. For the immediate future in 2012, expect to be paying a premium for the new LED technology.
How does the OLED display work?
An OLED display works in a similar manner to that of an LED display, but with no backlight. This enables the monitor or screen to display deeper, more intense levels of color, particularly darker colors.
What is the difference between solid state led and normal led?
Nothing. An led is a solid state device.
Which company will be producing the largest OLED TV soon?
OLED is the latest display technology to be introduced to the domestic television market. It is impossible to predict the largest OLED television and indeed, a little pointless to look at size as a milestone in LED television technology. OLED allows LEDs to be printed onto a substrate at very small sales so it is ideal for small screens. As the screen size increases, conventional LEDs become more viable than OLED. The largest true LED driven screens are those seen in open air and concerts, up to 40 feet wide or more. At present, commercial factors will decide the largest OLED display to be marketed. Those people who are looking for huge screens still have an option to consider conventional LED displays. Note that LED displays referred to here means the displays that use LEDs to generate the image and not as back lights for LCD displays.
How does an oled tv emits light on its own I have heard that an oled tv does not use the support of backlights and produce images by emitting its own light?
OLED stands for organic light emitting diode. Like conventional LEDs, OLEDs emit light in a very controlled fashion. OLED technology allows high a density of LEDs to be produced and is likely to become a very common technology for television in the coming years. LCD televisions use a static light behind the LCD panel. The light remains on all the time and LCD shutters open and close to control the amount of light that is passed through. OLED displays do not use a separate light source as each LED emits light as required. Every pixel requires a red, green and blue LED which between them can produce any color at any brightness. Note: Many televisions are advertised as LED televisions. With a very few exceptions, the LED refers to the illumination, with LEDs replacing cold cathode tubes as the light source. The active display technology is still LCD so these are not true LED televisions in the way that OLED displays are.
What is the difference between led and halogen lights?
Halogen light glows and LED is dull.
