The invention discloses a near-eye display module which includes at least one projection module, a bracing structure, and a control unit, releasing the eye's focus from a fixed plane. A projection module consists of more than one projection units, and the bracing structure functions as a holder for these projection units. A projection unit includes a display panel, a converging device which converges the light beams incident onto or outgoing from the display panel, and a deflection aperture which deflects the light coming from the converging device. The viewer wears two such near-eye display modules as eye-glasses. In the near-eye display module corresponding to an eye, the projection units of a same projection module jointly project at least one whole image to this eye, for VAC-free (Convergence-Accommodation conflict-free) three dimensional (3D) display based on Maxwellian view or multiple-images-one-eye.
