Key Features
One of the most important, if not the most important, components of a portable DVD player is its display, or screen. The size, and other characteristics, of the screen determine the quality not only of what you actually see, but also the overall dimensions, and weight, of a portable DVD player. Most LCD (Liquid Crystal Display) screens, nowadays, are TFT (Thin Film Transistor), or active matrix, in design, and offer bright, colour rich, results, even in conditions of bright ambient light. The Nextbase N2 SDV47 model, for example, is a tablet style portable DVD player, with a 7 inch, TFT display, while the Nextbase DVM235 model features a pop up, 3.5 inch, TFT display.
Screens as small as 4 inches, and as large as 17 inches, measured diagonally, are available, with 7 inches being typical. Do remember, however, that while a larger screen can be easier on the eyes, if you intend to view for long periods, the player, itself, and its batteries will, by necessity, also be larger, and heavier.
