Basic information of LCD TV:-

LCD (liquid crystal display), black and color images produced by selectively filter white light. The light is usually caused by a series of cold cathode fluorescent lamps (CCFL) back of the screen, although some displays a light source white or colored LED instead. Individual liquid crystal shutter, arranged in a grid in the millions, open and close, so that white light passes through a metered amount. Every shot with a color filter, remove all but the blue (RGB) red parts, green, white light from the original source.

Efficiency:-

Modern LCD sets "dynamic light through a process known as power consumption has tried to address. This system is the darker areas of the image to find the check, and reduces the backlighting in those areas. Over the length of the screen, or CCFLs are long cylinders, the only change as a whole can be used to control the brightness of the screen, or at least wide horizontal bands. The only such credits as at the end of the film images, the techniques for making specific types .Sets using LEDs in the light of each LED is usually only a small number of pixels, 16 to 16, with patches are distributed. They are suitable for a wide range of dynamic images to one or more of the same small area, which allows adjusting. For
