Abstract

The invention features a multi-view display system based on planar- or circular-aligned light-restricted projection units. A light-restricted projection unit is constituted by a display panel, a directional imaging structure transmitting optical messages from the display panel along a specific direction, and baffles encasing the display panel/directional imaging structure pair for light blocking. During operation, all the light-restricted projection units project images to a common display zone. Each light-restricted projection unit generates two kinds of zones: VZ where light rays from all pixels of the display panel pass and PVZ where light rays from partial pixels of the display panel pass. With the light-restricted projection units being aligned closely, PVZs from different light-restricted projection units completely or partially overlap into a fusing zone (FZ). For each point in the FZ, light rays from pixels belonging to segments of different display panels pass. The spatial percents of different segments occupying their display panels change with the point location, resulting in changing views presented to the pupil moving from one VZ (or image area of one VZ) to its adjacent VZ (or image area of the adjacent VZ). With the help of these keeping-changed views, continuous motion parallax gets implemented. Furthermore, through introducing sequentially gated gating-apertures, perspective views corresponding to more viewpoints can be presented by the display system based on persistence of vision for better three-dimensional effects.
