Abstract
This disclosure describes stereoscopic flat panel display systems based on the polarization encoding of sequentially displayed left and right eye images. The systems comprise line-by-line addressed liquid crystal display (LCD) panels, illuminating back light units and polarization control panels (PCPs). Right and left eye images are written sequentially onto the LCD whose polarization is controlled by a substantially synchronously driven PCP. The backlight may be continuously illuminated, or modulated temporally, spatially or both, as can the PCP.

A method of displaying stereoscopic imagery on a flat panel display, the display having a backlight with a plurality of backlight illuminating segments operable to selectively provide light to a liquid crystal (LC) modulation panel, the LC modulation panel having LC modulation regions operable to modulate the light incident from the backlight, and a polarization control panel (PCP) operable to transform a state of polarization (SOP) of the modulated light incident from the LC modulation panel, the method comprising:
- controlling the PCP with one of left eye and right eye polarization control signals;
- and
- providing the light to selected LC modulation regions from selected backlight illuminating segments, wherein the selected LC modulation regions comprise sufficiently settled modulation regions operating in an image mode corresponding to the one of left eye polarization control signals and right eye polarization control signals.
A flat panel display operable to display stereoscopic imagery, comprising:
- a backlight with a plurality of backlight illuminating segments operable to selectively provide light;
- a liquid crystal (LC) modulation panel receiving the light from the backlight, the LC modulation panel having LC modulation regions operable to modulate the light incident from the backlight;
- and
- a polarization control panel (PCP) operable to transform a state of polarization (SOP) of the modulated light incident from the LC modulation panel;
- wherein the PCP is controlled with one of left eye and right eye polarization control signals, and wherein the light is provided to selected LC modulation regions of the LC modulation panel from selected backlight illuminating segments, the selected LC modulation regions comprising sufficiently settled modulation regions operating in an image mode corresponding to the one of left eye polarization control signals and right eye polarization control signals.
