An integrated imaging display system is provided. The system includes: a display device, and a polarization converting element, an optical path folding element, and a micro-lens array provided on a light emitting side of the display device. The polarization converting element is configured to convert light emitted from the display device into first linearly polarized light in a first polarization state and second linearly polarized light in a second polarization state; and the micro-lens array is configured to form a first three-dimensional display image in a first depth-of-field range based on the first linearly polarized light and form a second three-dimensional display image in a second depth-of-field range based on the second linearly polarized light. Two depth-of-field ranges in the imaging space of the system may be formed, which enlarges the depth-of-field range of the imaging space.
