ABSTRACT

The characterization of nondiscrete displays mainly focuses on the displays in both static and dynamic modes of operation. The main purpose of a display system is to faithfully reproduce the visual information as perceived by its image-gathering end. A display system is merely the end interface of a complete information transmission system that transfers visual information from a distant location acquired by optical, opto-electronic, or some other means to the eye of an observer. The average standard deviation of the pixel intensity levels from the intensity levels of the original image across several pixels is taken as the pixel error measure. A visual display may have excellent high-frequency response, but human perception is limited to a certain maximum frequency. A review of display specifications will reveal that square waves were more popular in the early days and sine wave responses have gained popularity only recently, owing to the advances in linear systems and communications theory and its interaction with optics.
