    摘要: A flat-panel liquid crystal display. The display includes a flat sheet of bistable chiral nematic liquid crystal material activated by a drive circuit that individually controls the display state of multiple picture elements. The driver circuitry activates the liquid crystal domains with various drive schemes which have any number of different phases to attain various addressing sequence times. At the end of each drive scheme, the texture of the liquid crystal material is allowed to provide either focal conic or twisted planar end states across the two-dimensional array of picture elements. Each drive scheme employs at least a preparation phase and a selection phase to predispose the liquid crystal material to one of the end states.

    摘要: Bistable cholesteric liquid crystal material is disposed between opposed substrates, wherein one of the substrates has a first plurality of electrodes facing a second plurality of electrodes on the other substrate, wherein the intersection of the first and the second plurality of electrodes forms a plurality of pixels. The material is addressed by applying a preparation voltage across the first and second plurality of electrodes and then subsequently applying a selection voltage across the first and second plurality of electrodes. The material is then allowed to relax for a period of time, whereupon the preparation and selection voltages are reapplied. These steps are repeated until the liquid crystal material obtains the desired reflectance.

    摘要: In image registration, a similarity measure is computed of first and second images (4, 6) offset at a plurality of relative axial offsets (30). A starting relative axial offset (40) between the first and second images is identified based on the computed similarity measures. An iterative image registration process is performed to relatively register the first and second images (4, 6) using the identified starting relative axial offset between the first and second images as an initial condition for the iterative image registration process. A starting relative in-slice offset (42) may also be identified as an in-slice offset effective to align corresponding slices of the first and second images (4, 6) offset at the starting relative axial offset (40), the identified starting relative in-slice offset also being used as an initial condition for the iterative image registration process.

    摘要: An image display method comprises: color coding a second image respective to an intensity spectrum with a portion or portions of the intensity spectrum set to be transparent to generate a color coded second image; combining a first image and the color coded second image to generate a fused image; and displaying the fused image. An image display system comprises: an image generating module configured to generate an image by color coding an input image in accordance with a colormap assigning colors to intensities of an intensity spectrum; a colormap modifying module configured to select a portion of the intensity spectrum to be transparent; and a display configured to display the generated image.
