Abstract
A display apparatus includes a passive matrix display element and can support full-color display. The apparatus includes a passive matrix display elementcomposed of a memory type display material, a row driverfor driving the scan electrode of the display element and a column driverfor driving the data electrode of the display element. A switching signal S/C is set to a segment mode during the falling period of a display-apparatus driving signal /DSPOF for preventing rush current caused at the falling edge of a frame signal FR. During this period, the former half of line data is transferred and outputted. Consequently, the falling period of the display-apparatus driving signal /DSPOF (i.e., time during which liquid crystal does not operate) can be shortened, thus improving the response characteristics of liquid crystal.
