Abstract

A display apparatus including an image generator, a projection lens set, a depth detecting module detecting the position of user, and a control unit is provided, wherein the control unit is electrically connected to the image generator, the projection lens set and the depth detecting module. An image displayed by the image generator is projected through the projection lens set and generates a floating real image between the projection lens set and the user. Each beam forming the floating real image has a light-cone angle θ. The image generator and the projection lens adjust the position of the floating real image according to the position of user. The size of the floating real image is L, the distance between two eyes of the user is W, the distance between the user and the floating real image is D, and the light-cone angle θ satisfies the formula of
