Pixel
If the question refers to an LED illuminated LCD television, there will be several hundred individual LEDs forming a single panel. A true LED television uses a separate LED for red, green, and blue dots at every pixel. A 1920 x 1080 pixel television has just over 2,000,000 pixels. Each one needs a red, a green and a blue LED so there will be a total of 6,220,800 LEDs making up the image.
Prices for led lcd televisions vary in price depending on how big you are looking for and what pixel you desire. For a 32inch 780 pixle led lcd television around $300 is a good price.
Led televisions use a different form of lighting to display each pixel on your television, thus producing a much brighter, more clear, and eye settling picture quality.
3 ways, each pixel is made up of 3 LED (Light Emitting Diode) each a different color, red, green, and blue, that is if you were asking in reference to a LED flat panel TV! !

LCD are little lights for each and every pixel, while plasma has two pieces of glass with plasma between the two.
Don't know what LED TV is? LED TVs have a picture made up of pixels. Each pixel consists of a cluster of LED lights. LED TVs are generally better suited for larger screens, and are brighter and more vibrant in color than LCD and various other television types. LED TVs also have other benefits, including lower power consumption, limited light leakage, balanced color saturation, full backlighting, and no mercury is used in the production.
Samsung makes good ones.
There are several good companies that sell great LED television sets. One of the leading companies is Samsung.
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.
Pixel Precise is "newer" in marketing terms, Perfect Pixel is already a year or so "old". Fact ist that Pixel Precise is the small brother of Perfect Pixel, while Precise has less processing power than Perfect. I tried to see if Perfect is "better" than Precise: to me it is invisible.... both are stunning !!
