Patent ID: 7158100

Claim:
A driving apparatus for driving a display panel which has a plurality of row electrode pairs aligned parallel with each other so as to serve as display lines on an internal surface of one of two substrates facing each other with a discharge space between the substrates, each row electrode pair including a first electrode and a second electrode, the driving apparatus comprising: electrode driving means for generating an electrical discharge within the discharge space by alternately applying driving pulses to the first row electrode and the second row electrode forming each row electrode pair; and driving control means for controlling application timing of the driving pulses so that a flow direction of a discharge current which flows between the first row electrode and the second row electrode of each of the row electrode pairs belonging to odd numbered display lines due to the electrical discharge is opposite to a flow direction of the discharge current which flows between the first row electrode and the second row electrode of each of the row electrode pairs belonging to even numbered display lines; wherein an impedance of a current channel for the discharge current which flows between the row electrode pair belonging to the odd numbered display line and the electrode driving means is substantially the same as an impedance of a current channel for the discharge current which flows between the row electrode pair belonging to the even numbered display line and the electrode driving means.
