Stereoscopic 3D liquid crystal display with segmented light guide
First Claim
1. A backlight for a stereoscopic 3D liquid crystal display apparatus, comprising:
- a light guide formed from a plurality of segments, each segment having a first side and a second side opposite the first side, and having a first surface extending between the first and second sides and a second surface opposite the first surface, wherein the first surface substantially re-directs light and the second surface substantially transmits light, and the plurality of segments are arranged substantially in parallel with the second surfaces transmitting light in substantially the same direction to provide backlighting for a stereoscopic 3D liquid crystal display;
a light source is disposed along only one of the first side or second side of each segment for transmitting light into the light guide from either the first side or second side;
wherein, each segment light source is selectively turned on and off in a particular pattern.

Abstract
A backlight for a stereoscopic 3D liquid crystal display apparatus includes a light guide formed from a plurality of segments. Each segment has a first side and a second side opposite the first side, and a first surface extending between the first and second sides and a second surface opposite the first surface. The first surface substantially re-directs light and the second surface substantially transmits light. The plurality of segments are arranged substantially in parallel with the second surfaces transmitting light in substantially the same direction to provide backlighting for a stereoscopic 3D liquid crystal display. A light source is disposed along only one of the first side or second side of each segment for transmitting light into the light guide from either the first side or second side. Each segment light source is selectively turned on and off in a particular pattern.
