MULTI-VIEW PIXEL DIRECTIONAL BACKLIGHT MODULE AND NAKED-EYE 3D DISPLAY DEVICE

摘要

A multi-view pixel directional backlight module and naked-eye 3D display device, the multi-view pixel directional backlight module comprising at least two rectangular light guide plates closely stacked together; a light-emerging surface of each rectangular light guide plate is provided with a plurality of pixels with different directionalities formed by a nanometer diffractive grating thereon; each rectangular light guide plate is provided with a light source set on at least one side edge; after a light from the light source set enters into an interior of the corresponding light guide plate, an emergent light shows at each of pixels of multiple pixel arrays on the light-emerging surface of the light guide plate. Through stacking multiple layers of light guide plates, the problem of interference between three light sources in one light guide plate is addressed, and a pixel directional rectangular light guide plate is implemented to enable the industrial application of this light guide plate having a multi-view function and directionality to naked-eye 3D display technology, and to address the problem unresolved in the prior art.
