Design and fabrication method of dynamic display film based on microlens array
Dynamic display technique based on microlens array and micropattern array can realize three-dimensional image with stereo effect. A design and fabrication method for microlens array and micropattern array integrated on polymer films was introduced. Design formulas for the periodorientation and displacement of dynamic pattern were derived by the proposed moire geometric method. Stereo effects of floatingsinking and relative shifting can be achieved by the proposed method. Aperiodic imaging mode for the dynamic pattern was studied. The aperiodic image that can appear and disappear with view angle varying is obtained. Dynamic displaying films were fabricated using lithography and embossing processwhose periodorientation and displacement were measuredshowing their maximum deviations from the theoretical values were 11%16% and 14%respectively. The proposed method could be applied for estimating the performance and fabrication tolerance of dynamic displaying films effectively.
