Abstract

The embodiment of the present invention discloses a projection device, comprising: a projection cavity, a light source, a scanning motor and a processor; the light source and the scanning motor are located inside the projection cavity, and the processor is respectively connected with the light source and the The scanning motor is connected; the scanning mirror of the scanning motor is provided with a reflective layer, and the reflective layer is used to reflect the light emitted by the light source. The embodiment of the present invention has the advantages that the reflection range of light can be enlarged and the projection angle of view can be enlarged.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a projection device and method. Background technique [0002] Currently, the near-eye light field display is used in Augmented Reality (AR for short) and Virtual Reality (VR for short) technologies, which can bring more realistic 3D display effects and become the development trend of 3D display technology in the future. . In light field display technology, wide view angle micro-projection devices are the basic components for generating light fields, and are being researched by many manufacturers. In a digital light processing (Digital Light Processing, DLP) system, the size of the digital mirror device (Digital Mirror Device, DMD) determines the size of the projection field of view (Field Of View, FOV), that is, the larger the size of the DMD, the larger the projection The larger the FOV, the smaller the size of the DMD and the smaller the projected FOV. However, t...
