A 1000-SCANNING-LINE DISPLAY SYSTEM WITH HIGH EXPANDABILITY

To realize a single display system for all kinds of TV image informati on 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 picture quality. This study confirmed that a minimum deterioration of a vertical respon se and no degradation of the motion of an image can be obtained and th at the aliasing and flickering effects caused by the use of a conventi onal interlaced scanning can be eliminated. These advantages are due t o a newly developed scan conversion method which employs a double fiel d-rate and wobbling interlaced scanning within four fields. New multim edia such as the ATV, HD-TV, digital TV, and 3D-TV can be displayed in the single display system. Furthermore, in the new platform using thi s technology, it is easy to interface with the HD and 3D package media and image-sensing media.
