Abstract: The invention discloses a circumferential laser dynamic display device, including an inner frame, having an inner frame pattern with multiframe microstructures made on surface; a sheet metal part, at least provided with first and second through holes, wherein the inner frame pattern is directly irradiated by a first beam of laser through the first through hole and by a second beam of laser through the second through hole; and a rotating shaft, with one end fixedly connected with a driving shaft, and the other end rotatably connected with the inner frame pattern. The rotating shaft can drive the inner frame pattern to do translational movement when rotating; wherein the translational movement of the inner frame enables the inner frame pattern to do circumferential movement relative to laser. The dynamic display device disclosed by the invention has simple structure, reasonable design and low production cost, and achieves circumferential dynamic image display.

Abstract: The present invention discloses a laser animation display method. A display system includes three parts, i.e., a laser source, a diffraction optical element and a mechanical driving device. The display method includes the following steps: S1: the laser source emits laser at first, and the laser is caused to be incident on the pattern of a first microstructure on the diffraction optical element; S2: the diffraction optical element is driven by the mechanical driving device to translate to irradiate the pattern of a second microstructure of the diffraction optical element with the laser, and the patterns on other microstructures are sequentially irradiated with the laser according to the same method; and S3: cyclic movement is kept, thereby achieving an animation effect on a screen. The present invention implements laser animation display on the premise of no additional motion control unit and almost no increase of the system size and cost.
