LCDA liquid crystal display is basically a flat glass substrate made up of pixels that are laid in front of a light source or reflector. Each pixel is made up of a layer of liquid crystals between two electrodes and polarizing filters. When in a relaxed state, the crystals arrange themselves in a helix or 'twist', allow light to pass through. When charged, they align themselves and the result is that light cannot pass through, resulting in an unlit pixel. LetterboxBecause movies are often shot in a widescreen format and not all TV's are widescreen, the process of letterboxing is used to reduce the size of the visuals to keep the original aspect ratio that the movie was filmed in. This method ensures that the movie is shown as the makers intended and that frames are not cropped, as in the pan and scan process. This process does mean that 'black bars' which are unused areas of the screen are visible at the top and bottom of the image - giving what we now term the LTBX effect.
