Problems solved by technology

Although the scanning angle of scanning display components such as digital micromirror devices (Digital Micromirror Device, DMD) is adjustable, the scanning angle of such scanning display components is limited, and it is difficult to meet the display requirements of such scenes
However, if multiple display devices are used, the cost is high and manual adjustment is required

Abstract

The embodiment of the invention discloses a scanning display module and near-to-eye display equipment, scanner groups with different orientations are additionally arranged in the scanning display module, multi-directional scanning output is realized, the scanning display module can be integrally kept in a relatively small size, and miniaturization of the near-to-eye display equipment is facilitated.

Description

[0001] This application is a divisional application of a patent with the application number: "201910364343.9" and the title of the invention: "A scanning display module and near-eye display device". technical field [0002] The present application relates to the technical field of scanning display, in particular to a scanning display module and a near-eye display device. Background technique [0003] As an emerging display technology, scanning display imaging can be used in various display scenarios such as projection display and near-eye display. [0004] In the prior art, a display device containing scanning display elements inside can realize a certain range of display imaging. In some application scenarios, the display device may be required to output images with different orientations or positions. Although the scanning angle of a scanning display element such as a digital micromirror device (Digital Micromirror Device, DMD) is adjustable, the scanning angle of such a ...
