Abstract: An integrated dual day night backlight includes a flat channel light source with an auxiliary night light source suitably filtered to remove infrared components from the illumination. In alternative embodiments, the night light can be a separate bulb or it can be separate light channels within the flat channel source. The night illumination is directed through the edge of the light transmissive face plate that covers the main or day channel. The light directing means can be an inner reflecting surface of the face plate or can be a separate reflective element that redirects the illumination from the night channel through the edge of the transmissive face plate.

Abstract: A digital address filter is provided which converts straight-line and arc analog stroke data into digitized images which comply with Bresenham raster display criteria and can be displayed on a raster scanned monitor or LCD. Data collected over a preselected (M pixel.times.M pixel) spatial window are repetitively matched against a set of pixel template patterns permitted by the Bresenham criteria. After each full-frame iteration, the display pixel(s) corresponding to the best-fit templates are lighted.
