Security display apparatus

摘要

A security display apparatus is provided including an image processor (120) which reverses a normal image to create a reverse image which is a negative of the normal image, and a display unit (100) which displays the normal image and the reverse image. The display apparatus further includes three-dimensional (3D) glasses (200) which filter the reverse image such that the reverse image is blocked from a user by the glasses and the normal image is transmitted to the user through the glasses.
