Seiko Instruments Announces First Raster Scan Graphic Display With Hardware Anti‐Aliasing
Information Display · 1982
The first raster scan graphics terminals to include integral display anti-aliasing at the hardware level were introduced recently by Seiko Instruments U.S.A., Incorporated, Santa Clara, CA. The newest members of Seiko Instruments' D-Scan series of graphic terminals, introduced abroad nearly three years ago, the GR-2412 7-color intelligent terminal and the GR-2212 intelligent monochrome terminal are said to present the display quality of vector-type terminals, but with all of the features and functions traditionally provided with raster scan technology. Both terminals are 19-inch screen models that use a viewable resolution of 1024 × 780 pixels to maintain the preferred 4:3 aspect ratio. Direct addressability extending to 4096 × 7094 points, located within a coordinate space of 32k × 32k, allows for true zooming, scaling, and easy manipulation of large data bases. Other Seiko Instruments products are the GR-60 high resolution hard copier and a pair of graphic digitizers.
