How Are Rear Projection TV Screens Made?
Introduction Rear projection televisions have come a long way since they were first introduced on the market. Not only do they provide a better quality picture, but they are also made out of materials that allow them to cost less and last longer. There are three main types of rear projection televisions on the market today. These include digital light processing televisions (DLP), liquid crystal on silicon (LCOS) and liquid crystal display (LCD). Liquid Crystal Display Screens LCD television technology allows for very impressive displays. Liquid crystal displays are the most common type of rear projection television on the market today. Each pixel contains three separate colors: red, blue and green. An electrical charge is used to determine which color or combination of colors is displayed to you. However, there is a lot more depth that goes into producing an LCD television. Every pixel that is in an LCD television is made up of electrodes in between two layers of polarized molecules.
