Abstract
Systems and methods are provided for displaying three-dimensional image data on a display having a light source modulation layer and a display modulation layer. The light source modulation layer has light sources for providing spatially modulated, spectrally separated light for displaying time-multiplexed left and right eye images. The display modulation layer has pixels for spatially modulating the amount of light received from the light source modulation layer.
Claims25
A display system for displaying three-dimensional image data comprising left-eye image data and right-eye image data, said display system comprising:
- a light source modulation layer comprising a first plurality of light sources and a second plurality of light sources, said first plurality of light sources and said second plurality of light sources being operable to provide spatially-modulated light for display of said left-eye image data and said right-eye image data, respectively;
- a display modulation layer comprising a plurality of pixels operable to spatially modulate light received from said light source modulation layer;
- and
- a controller operative to
- determine a set of left-eye light source modulator control values based at least in part on a set of left-eye image data, said set of left-eye light source modulator control values configured to produce a left-eye luminance pattern expected to be received on said display modulation layer,
- determine a set of right-eye light source modulator control values based at least in part on a set of right-eye image data, said set of right-eye light source modulator control values configured to produce a right-eye luminance pattern expected to be received on said display modulation layer,
- make a comparison of at least some of said set of left-eye light source modulator control values and at least some of said set of right-eye light source modulator control values, and
- depending on said comparison, adjust a set of left-eye display modulation layer control values based on said right-eye luminance pattern.
A method of displaying three-dimensional image data on a display system having a light source modulation layer and a display modulation layer, said method comprising:
- receiving a set of left-eye image data and a set of right-eye image data;
- determining a set of left-eye light source modulator control values based at least in part on said set of left-eye image data, said set of left-eye light source modulator control values for driving a first plurality of light sources of said light source modulation layer;
- determining a set of right-eye light source modulator control values based at least in part on said set of right-eye image data, said set of right-eye light source modulator control values for driving a second plurality of light sources of said light source modulation layer;
- determining a left-eye luminance pattern expected to be received on said display modulation layer from said first plurality of light sources based at least in part on said set of left-eye light source modulator control values;
- determining a right-eye luminance pattern expected to be received on said display modulation layer from said second plurality of light sources based at least in part on said set of right-eye light source modulator control values;
- making a comparison of at least a portion of said set of left-eye light source modulator control values and at least a portion of said set of right-eye light source modulator control values;
- and
- depending on said comparison, adjusting a set of left-eye display modulation layer control values based on said right-eye luminance pattern.
