    摘要： Methods and arrangements are provided for use in a printer and associated computer(s). The printer is configured to periodically and/or automatically detect when changes are being made to a print media supply tray and output/display the current configuration of the print media supply tray for use by the user and/or programs running on the computer. The current configuration of the print tray is determined using detectable mechanisms that are either hardware and/or software implemented. The configuration of the supply tray is displayed to the user via the printer display, a tray-mounted display, and/or though a graphical user interface (GUI) on the computer. The configuration is defined by at least the size and type of the print media associated with the supply tray.

    摘要： The invention involves a novel method and structure for utilizing homeotropic vertically aligned nematic liquid crystal cells in the production of high contrast microdisplays. Two circular polarizers are used in order to propagate circularly polarized, rather than planar polarized, light through a liquid crystal cell. The use of circularly polarized light eliminates the liquid crystal director alignment requirements for the transmittance of light necessary for planar polarized light. With no director alignment requirement, it is possible to use perfectly homeotropic vertically aligned nematic cells irrespective of domain size and shape because fringing field induced director tilt will not decrease the transmittance of the liquid crystal cell.
