Abstract

The invention provides an ultra wide angle micro projection device (100), comprising a micro scanning projection module (10). The micro scanning projection module (10) comprises a video image signal processor (11), one or more laser drivers (12) coupled to the video image signal processor (11), one or more scanning drivers (14), a laser module (13) coupled to the laser driver (12), and an MEMS scanner (15) coupled to the scanning driver (14). The device (100) further comprises an optical aspheric mirror (16) arranged on the light path of a light beam projected from the micro scanning projection module (10), a plurality of structure shape objects (162) with specific orientations are arranged on a base surface (161) of the optical aspheric mirror from the center to the periphery, and the distribution of the structure shape objects has a certain corresponding relation with the pixels of an image formed by the light beam projected from the micro scanning projection module (10). The optical aspheric mirror (16) adjusts the light beam projected from one or more MEMS scanner (15).

Description

technical field [0001] The invention relates to a micro-projection device, in particular to a laser micro-projection device for realizing ultra-wide-angle projection. Background technique [0002] With the development of laser technology, laser micro-projection equipment and related products are gradually mature and applied in daily work and life. The micro-laser projection device is easy to carry and easy to operate. At the same time, the laser light source has very good stability and consistency. The output video projection screen has the advantages of high resolution, low color and picture distortion. In addition to being used in daily office environments, micro-laser projection devices are also gradually entering the home environment. For example, use a micro-laser projection device to connect the video source to output video and project it to a screen set at home or a flat interior wall, and play stored images, videos or files on the display screen or a flat wall on th...
