Looking at Displays

Lucien M. Biberman

Displays, like beauty, are meant to be seen and — usually — to be understood. Thus it would seem important that displays present good clear images, but unfortunately there is almost no universal agreement and no real standards for display-image quality. Much of that present difficulty stems from the very large variety of displays, the large variety of basic processes for translating a signal into a picture in the different forms of displays, the large variety of techniques for remembering and/or storing the image in or for display, and the great range in the subject matter and format to be displayed.
