ABSTRACT:
In a display apparatus such as a liquid crystal display or the like, which adds a switching element for each of the display picture elements arranged in a matrix shape so as to effect the active matrix driving operation, a drive system exits which is capable of varying the number of the scanning lines on the display. The drive system in the simple construction produces a display of a number of input lines, greater in number than the number of scan electrodes on the display apparatus, without producing practical deterioration in the display quality.
