ABSTRACT:
A projection device is provide, including a projection module having at least an optical lens, the projection module receiving data and converting display data into an optical image to be projected on a display area by the optical lens. The projection device can be positioned substantially close to the display area. This allows the projection device to directly project the optical image on the display area without having to adjust a projection angle, and also makes the projected image free of obstruction from movement of a user. Therefore, data display and projection operation can be conveniently and efficiently implemented.
