Abstract
Abstract A flat panel matrix display pixel structure emulates raster scan cathode ray tube shadow mask resolution. A display generator connected to anti-aliasing and/or dot flair circuitry activates the display. A selected pixel is fully activated and surrouding pixels are activated at a lower luminance level. As a function of the pitch of a shadow mask cathode ray tube the pixel density and the horizontal and vertical pixel spacing are derived for a monochrome matrix display, and the pixel density and the horizontal and vertical triad spacing are derived for a color matrix display panel.
