Patent ID: 7358931

Claim:
A method for driving a plasma display device comprising a panel which comprises a first substrate on which two or more pairs of electrodes are formed, each pair being made up of a scanning electrode and a sustaining electrode, both being parallel to each other and a second substrate on which two or more data electrodes are formed in a manner in which each of said data electrodes and each pair of electrodes intersect each other, said method comprising: a step of controlling display operations in a scanning period during which a scanning pulse is sequentially applied to said scanning electrode to cause writing discharge to occur according to a video signal in each of sub-fields obtained by dividing one field displaying one video signal into two or more sub-fields, in a sustaining period during which a cell having undergone said writing discharge is turned ON in each of said sub-fields, and in an initializing period being set before said scanning period during which wall charges and space charges accumulated in said cell before said scanning period starts are initialized in each of said sub-fields; and a step of changing, in at least one sub-field out of said two or more sub-fields making up said one field, a change rate of a potential difference between said scanning electrode and said data electrode according to a panel temperature and/or cumulative operating time of said panel during a wall charge adjusting period existing in a final portion of said initializing period, during which said potential difference between said scanning electrode and said data electrode changes gradually.
