In one embodiment, a display system comprises a plurality of emitters, said emitters emanating light into an optical path; a first modulator, said first modulator comprising a plurality of colored subpixels and wherein said first modulator transmitting light emanating from said emitters in said optical path; and a color notch filter, said color notch filter placed in said optical path for conditioning or convolving light together with said first modulator.

Abstract: Edge lit displays are lit via a set (or individual) lighting elements. Each element projects light onto, for example, a zone which is then utilized directed as a backlight toward an LCD panel. An amount of light incident on any area (e.g., pixel) of the LCD panel (or SLM/series of SLMs) is calculated based on a sum of contributions from each zone. A similar process may be utilized for other lighting configurations. An amount of modulation performed by the LCD panel is then calculated based at least in part on lighting from the zones which may include brightness and varying levels of color content.

Abstract: The present disclosure includes, among other things, systems, methods and program products for identifying a drawing scale for a graphical view of a drawing, the drawing scale specifying a ratio of two units; selecting one or more annotations associated with the view that support the drawing scale, each of the selected annotations associated with context for the drawing scale, the context specifying one or more of: the annotation's position in the view, the annotation's style in the view, or the annotation's rotation in the view; adding a graphical representation of each of the selected annotations to the view according to the drawing scale and each annotation's respective context; and removing any one or more of the annotations from the view that does not support the drawing scale.

Abstract: A display including an image-generating panel and at least one contrast-enhancing panel, a cross BEF collimator between a backlight and one of the panels, and a polarization-preserving diffuser (e.g., holographic diffuser) between the panels. Typically, the contrast panel is upstream of the image panel, and a reflective polarizer is positioned between the cross BEF or and contrast panel, with the reflective polarizer oriented relative to an initial polarizer of the contrast panel. Polarization of light transmitted by the reflective polarizer matches that transmitted by the initial polarizer. Collimated light propagating from the cross BEF collimator toward the contrast-enhancing panel is given a polarization bias by the reflective polarizer, which reflects incorrectly polarized light back toward the cross BEF collimator.

Abstract: A high contrast high resolution display is produced using an image chain comprising a plurality of downstream high resolution modulators. The modulators may be illuminated by a locally dimmed backlight. Polarization control is maintained throughout the image chain via reference and analyzing polarizers combined with non-depolarizing layers. The modulators are grayscale and modulate at the sub-pixel level. A color panel may be maintained for embodiments that require color. Diffusion in the chain is matched to a resolution of the image content carried in the light such that the effects of local dimming and sub-pixel resolution are preserved. Brightness enhancement films may be utilized to enhance brightness and maintain polarization control.
