What is Difference between direct view storage and flat panel display?

"Flat panel" screens refer to any screen that does not have a cathode ray tube, the large glass tube that takes so much depth inside a conventional television. Flat panel screens include plasma, LCD and LED and are normally about 5 inches deep. Wide screen describes the shape of the screen. Conventional screens are a ratio of 4 wide to 3 high. Widescreen normally refers to a ratio of 16 wide by 9 high although there are other ratiOS that can be described as widescreen as well. Flat panel screens and CRTs come in 4 : 3 and 16 : 9 formats. Flat panel is a thin television, widescreen is what most HDTVs are. Widescreen is basically a movie style screen. It's a lot wider than it is high.
