Two novel methods are proposed which enhance the angular sampling rate of the integral floating display by adopting dynamically variable apertures in front of the lenslet array or the floating lens. Adopted dynamically variable apertures are opened sequentially in synchronization with proper elemental images to subdivide the angular sampling step by time-multiplexing method. Our proposed method can enhance the angular sampling rate, which is related to an expressible longitudinal range, without sacrificing other visual quality factors in tradeoff relationship. Especially, our proposed method with apertures on the floating lens provides two-dimensional/three-dimensional convertible feature to integral floating display system.
