A holographic display panel, a holographic display device and display method

The present invention provides a holographic display panel types, a hologram display apparatus and a display method relates to the field of display technology, to achieve dynamic holographic display. The display panel includes a plurality of holographic depth display units, each display unit comprises a depth of at least two adjacent pixels, each pixel comprising a plurality of sub-pixels; depth of each display unit further includes a plurality of phase plates, each sub-pixel along a phase plate which corresponds to the direction of light, the phase plate a phase plate for controlling the diffraction angle of the light emitted. The diffraction angle of the same pixel in each of the phase plate of sub-pixels corresponding to the same, and with a depth of field of the display light after the unit different pixels through the phase plate exit different diffraction angles, so that by the same depth display light means emitted, the reverse extension lines intersect at a position at a depth.
