Patent ID: 7002535

Claim:
A display apparatus for displaying an image on a display panel, said display apparatus comprising: a display panel provided with a plurality of first electrodes, a plurality of second electrodes arranged parallel to said first electrodes and a plurality of address electrodes arranged so as to cross to said first and second electrodes; a first electrode drive circuit supplying first electrode sustain pulses to said plurality of first electrodes; a second electrode drive circuit supplying scan pulses and second electrode sustain pulses to said plurality of second electrodes; an address drive circuit supplying address pulses based on the image to said plurality of address electrodes; and wherein said second electrode drive circuit includes a plurality of line drive circuits connected to said plurality of second electrodes respectively, and each of the line drive circuits has a driving switch for supplying said second electrode sustain pulses to the corresponding second electrode selectively, wherein said driving switch also supplies said scan pulses to said corresponding second electrode selectively, and wherein said driving switch includes: a first switch element which supplies high level voltage of said second electrode sustain pulses and high level voltage of said scan pulses to said corresponding second electrodes, and a second switch element which supplies low level voltage of said second electrode sustain pulses and low level voltage of said scan pulses to said corresponding second electrodes.
