Title: Display device and scanning method for display device
Inventor: KONOUE AKIHIKO
IPC: G09G3/28
Filed: 1989-10-09
Abstract: PURPOSE:To improve the continuity of an image at the border of each block in a display area and to preclude deterioration in picture quality by performing scan driving so that the scanning direction of each block is inverted at its border. CONSTITUTION:Scanning points in plural divided blocks are scanned symmetrically about the border line of each block. For example, the screen is divided into two upper and lower parts A and B and when a scanning line is in a right-to-left direction and the moving direction of the scanning direction is as shown by a solid line, the scanning line moves up from the border line in the block A, but when the moving direction is as shown by a dotted line, the scanning line moves to the border line from the upper and lower ends. When the screen is divided into three parts A, B and C, scanning lines in the respective blocks exist closely at the time of scanning nearby the border line, so there is little time difference of an image. Consequently, deterioration in picture quality due to discontinuity is eliminated.
