A novel high resolution light field display method based on polymer dispersed liquid crystal film is proposed. First, the virtual camera array is built to collect the light field information of the target object, so as to obtain its element image array. Then, according to the photoelectric characteristics of the polymer dispersed liquid crystal, high resolution light field display results can be obtained by adjusting the applied voltage of the polymer dispersed liquid crystal film and using the transient/afterglow effect of the human eye. The experimental results show that compared with the traditional method, the proposed method is simple and has higher display quality, and the peak signal-to-noise ratio of the presented image is improved by about 11%. In addition, the system built by the proposed method is less difficult and practical.
