Abstract

The invention provides a virtual and augmented reality combination device. In a shell, there are arranged with a display screen capable of emitting a light source image and a positive-focal-length optical system. In a virtual reality mode, the positive-focal-length optical system performs virtual magnification on the light source image and then projects the virtually-magnified light source image into eyes of a user. In an augmented reality mode, a partial penetration and partial reflection module is arranged on a position below the shell and corresponding to the positive-focal-length optical system. The light source image converted by the positive-focal-length optical system is transmitted into the eyes after passing through the partial penetration and partial reflection module, so as to obtain an augmented reality image. Therefore, the virtual reality and the augmented reality can be integrated into the same device by utilizing the detachable partial penetration and partial reflection module, so as to achieve the aim of freely switching and regulating the virtual reality mode and the augmented reality mode.
