Problems solved by technology

[0003] The adjustment of the deflection direction of the digital micro-mirror mirror is realized by a rotating device that acts like a hinge under it. Since the rotating device is a mechanical structure, long-term deflection in a certain direction will cause the mechanical properties of the rotating device to age and eventually lead to mechanical structure failure. , which directly affects the service life of the DLP projector
[0004] Therefore, it is a technical problem to be solved in the prior art how to realize that the digital micromirror device avoids the aging of the mechanical properties of the rotating device in the process of projection display.

Abstract

The invention relates to a method for realizing driving control of a digital micro-reflection lens in projection imaging. The method comprises the steps of: selecting a specified time period accordingto the primary color display time of a projected pixel in the projection display of each frame of image through the digital micro-reflection lens, and within the specified time period, driving and controlling the digital micro-reflection lens to deflect positively and negatively according to a preset number of times. By adopting the method provided by the invention, the anti-aging of the rotatingdevice in the digital micromirror device can be realized.

Description

technical field [0001] The present application relates to the technical field of image projection, and in particular to a method for realizing driving control of digital micro-reflector mirrors in projection imaging. Background technique [0002] Digital Micromirror Device (DMD, Digital Micro mirror Device) is the core device in a DLP (Digital Light Processing, Digital Light Processing) projector, on which many digital microreflectors are integrated. When the DLP projector is performing image projection, each A digital micro-mirror mirror is a pixel point. By controlling each digital micro-mirror mirror to deflect a certain angle in the positive and negative directions to reflect the incident light, the reflected light is displayed on the projection screen as an image through the projection lens. [0003] The adjustment of the deflection direction of the digital micro-mirror mirror is realized by a rotating device that acts like a hinge under it. Since the rotating device is...
