In the laser video display system, video image with low contrast and inferior image quality are usually happened due to the effects of the background interference fringes. Aiming at eliminating such kind of interference fringes, multi-pixel scanning method is proposed in the laser TV, which breaks the technical bottleneck of scanning method. What is more, compared with traditional display, a great improvement can be fulfilled in image quality. Through deep analysis and research on the mechanism of laser interference in the process of laser display, a multi-pixel scanning method is presented in this paper, and relevant device has also been designed. This method can be used to achieve offset interference as well as projecting display. It can been seen that excellent display effect can be obtained by this method and technical defection in scanning laser display can be overcome as well as laser interference fringes in projecting style. It is demonstrated that this method has referenced and practical evaluation for offering an effective method in the research of laser TV.
