Abstract
The invention discloses a display module with the divergence angle of an outgoing beam constrained again by the corresponding deflection aperture, which includes a multi-view display structure, a deflection-aperture array and a control device. The multi-view display structure includes a display screen, a light-splitting device, and a backlight-source assembly for providing backlights when a backlit-type display screen is adopted. The light-splitting device guides light beams from each group of pixels or sub-pixels to the corresponding viewing zone. A deflection aperture with a small size is designed for constraining the divergence angle of deflected light beams. Multiple deflection apertures play the function of enlarging the field of view, which is very limited when only a single deflection aperture exists. With orthogonal characteristics being assigned to deflection apertures for suppressing noise and/or for projecting more views, three-dimensional display with natural focus will get implemented with large field of view and low noises.
