Liquid Crystal Display Liquid crystal display (LCD) is quickly becoming the most popular version of the flat screen TV. For one thing, the variety of screen size is much greater. Only LCD TVs come in screen sizes less than 42 inches, making them the choice for people looking for a smaller screen. Normally ranging from 15 to 65 inches, LCDs use cold cathode fluorescent lamps to shine a light through LCD shutters and color filters to produce the picture on the screen. Their lighter weight and lowered costs have caused LCDs to surpass CRTs in sales by 2007.
