LIGHT GUIDE PLATE APPLICABLE TO 3D DISPLAY

摘要

The present invention relates to a light guide plate applicable to 3D display. The light guide plate comprises an upper microstructure used as an upper surface of the light guide plate. The upper microstructure is perpendicular to a propagation direction of light rays emitted by a light source in the light guide plate and is in continuous convex-concave distribution on the light guide plate. Positions on the light guide plate are classified into a passing light side and a distance light side according to distances relative to the light source in a propagation direction of light. A height in a shape feature of the upper microstructure is represented by H, and a gap in the shape feature of the upper microstructure is represented by P. Distribution of the shape feature of the upper microstructure in the propagation direction of the light has a change and the change meets that a depth-to-width ratio H/P of the upper microstructure of the light guide plate at the passing light side is smaller than a depth-to-width ratio H/P of the upper microstructure of the light guide plate at the distance light side. The light guide plate applicable to 3D display in the present invention implements the uniformity of crosstalk at different positions during backlight scanning, and especially implements reduction of crosstalk at the distance light side, thereby integrally improving a 3D display effect.
