What is an LCD TV
Liquid crystal televisions (LCDs) use the principle of liquid crystals to emit light and image under the influence of voltage.
There are three kinds of liquid crystals that make up the screen: red, green, and blue, called the three primary colors. They are arranged in a certain order. These liquid crystals are stimulated by voltage to show different colors, and different proportions of the mix can show kaleidoscopic colors .
Therefore, the "dot" -accurate LCD TV is one level higher than the "progressive scan" ordinary TV. Currently, mainstream LCD TVs are 20-42 inches in size.
