Definition of Widescreen

What is widescreen? Widescreen images are images that are displayed within a set of aspect ratios used in film, television and computer screens. In the film, the widescreen film refers to any standard 1.37: 1 academy aspect ratio film provided by any film with an aspect ratio greater than 35 mm. Then, this post from MiniTool will provide more information about widescreen.

For TV, the original screen ratio of the broadcast is full screen 4: 3. From the 1990s to the early 2000s, 16: 9 widescreen TV monitors became more and more common at different paces in different countries. They are often used in conjunction with high-definition television (HDTV) receivers or standard definition (SD) DVD players and other digital television sources.

The aspect ratio (16: 9) supported by typical widescreens is different from traditional displays (4: 3) allowing them to display many movies and HD (1080p) videos in their original format. There is also a display style called UltraWide (21: 9), whose viewing area is about 33% wider than a traditional widescreen screen.
