Display and glasses

Abstract

A security display system including security glasses and a security display is provided. The security display includes a noise image generator, a synchronous packet generator, a display unit and an image asymmetry generator. The noise image generator generates a noise image signal according to a normal image signal. The synchronous packet generator outputs a synchronous packet to the security glasses. The display unit displays a normal image according to the normal image signal in a glasses-open period and a noise image according to the noise image signal in a glasses-shut period. The image asymmetry generator corresponds to a first brightness integral when displaying the normal image in the glasses-open period, and to a second brightness integral when displaying the noise image the glasses-shut period. The second brightness integral is greater than the first brightness integral.
