How does an LCD television work?
LCD (liquid crystal display) televisions work by passing an electric current through liquid crystals that are sandwiched between two panes of polarized glass. Liquid crystals are made up of minuscule segments called pixels. These pixels do not create light themselves, in the same way as the phosphates in a plasma screen do, and therefore an LCD television requires the use of a fluorescent bulb behind the screen. To create an image, the individual pixels twist or untwist to allow or block the passage of light from the bulb, while the pixels themselves divide into sub-pixels of red, blue and green and recombine to produce the correct color. Advantages of LCD televisions LCD televisions do not produce either radiation or excessive heat, which makes them more environmentally friendly and cost effective to use than plasma equivalents. LCD televisions do not suffer from screen burn but could potentially suffer the burn out of individual pixels that would leave permanent white spots on your s
