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.

∙ 11y agoMost televisions advertised as LED are in fact LCD televisions that use LED backlighting instead of cold cathode lighting. They are rather more efficient and the more compact nature of the LED panel makes for a thinner screen depth than conventional cold cathode models. However, the LCD display technology is identical.
OLEDs (organic light emitting diodes) can be manufactured to very fine tolerances and can be produced small enough to be used as a television display. Unlike LED lit LCD, a true LED television uses a red, green and blue LED in each pixel to directly produce light at that point. This means there is no need for an additional lighting layer, so screens can be even thinner. It also allows for higher contrast ratios and the power used is directly proportional to the brightness of the image. If the image is black, all the LEDs are off and no power is used. Compare this to an LCD model where the back light remains on even when the image is black.
OLED technology is expensive at the moment but as production volumes increase, expect the costs to fall. There is little doubt that the simpler assembly of an OLED television means it will become the standard display type in the next few years.
Currently, OLEDs are criticized for their short life in some circumstances. This issue will be overcome as developments improve reliability in the future.

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.
What is the difference between OLED LCD and Plasma panels particularly with energy efficiency and the constructional complexity?
This is the link where u can get better idea about LCD and OLED I found thhis will be very help full to this tpoic http://www.oledtvzone.com/guides/oled-vs-lcd-tv
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'.
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.
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 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.
The difference between warm led and cold led?
Warm led is about 3000K and cold led is 5000-6000K
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 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.
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 solid state led and normal led?
Nothing. An led is a solid state device.
