A 1000-scanning-line display system with high expandability

To realize a single display system for all types of TV image information with different scanning-lines and indicating-channels, a new single-scanning technology with a scan conversion method has been studied by response analysis and by experimental evaluation of the picture quality. This study confirmed that a minimum deterioration of a vertical response and no degradation of the motion of an image can be obtained and that the aliasing and flickering effects caused by the use of a conventional interlaced scanning can be eliminated. These advantages are due to a newly developed scan conversion method which employs a double field-rate and wobbling interlaced scanning within four fields. New multimedia such as the ATV, HDTV, digital TV, and 3D-TV can be displayed in the single display system. Furthermore, in the new platform using this technology, it is easy to interface with the HD and 3D package media and image-sensing media.
