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 present application relates to a method for realizing driving control of a digital micro-reflection mirror in projection imaging, the method comprising: in the projection display of each frame of image through the digital micro-reflection mirror, selecting a specified display time according to the primary color display time of the projected pixels time period; within the specified time period, the digital micro-reflection mirror is driven and controlled to perform positive and negative deflections according to a preset number of times. The anti-aging of the rotating device in the digital micromirror device can be realized by using the method provided in the present application.

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 a digital micro-reflective mirror in projection imaging. Background technique [0002] Digital Micromirror Device (DMD, Digital Micromirror Device) is the core device in DLP (Digital LightProcessing, digital light processing) projector, on which many digital micro-reflection mirrors are integrated. When the DLP projector is performing image projection, each A digital micro-reflection lens is a pixel point. By controlling each digital micro-reflection lens to deflect a certain angle in the positive and negative directions, the incident light is reflected, so that the reflected light is displayed on the projection screen through the projection lens. [0003] The adjustment of the deflection direction of the digital micro-mirror lens is realized by a rotating device that acts like a hinge below it. Since the rotating ...
