Abstract: A near-eye display system includes a display assembly comprising at least one display panel and a display driver to drive the display assembly to display a sequence of frames in a low-persistence mode based on a frame clock signal having a first frequency. The near-eye display system further includes a pair of liquid membrane lenses facing the display assembly, and a lens driver having an output coupled to an input of each of liquid membrane lenses of the pair, the lens driver to generate at the output a periodic, continuously variable driving signal having a second frequency, wherein the first frequency is an integer multiple of the second frequency. As the liquid membrane lenses are synchronized with the low-persistence display of the sequence of frames, each displayed frame is perceived through the liquid membrane lenses at a different nearly constant focal depth, and thus creating a perception to the user of multiple focal planes in the displayed imagery.
