LCD Television

LCD television work through the use of liquid crystals, thus their name LCD or Liquid Crystal Display. Liquid crystals are a material that is sort of in between the two states of matter we commonly refer to as solid and liquid. This material was first discovered in the late 19th century, but it wasn’t until the second half of the 20th century that a practical use was found for them.

The process by which an LCD television works is long and tedious and much different than that of CRT or plasma screens. Essentially, the liquid crystals are set between two charged electrodes, usually in the form of plates. When an electric charge is run through the liquid crystal, the material rearranges itself so that light can penetrate through certain points, thus creating a visual display.

Like other types of televisions, an LCD television also uses colored pixels. Each pixel has three sub-pixels; red, blue, and green. By varying the applied voltage, each can create up to 256 different shades, resulting in an amazing 16.8 million different possible colors.
