Abstract:
A display apparatus, comprising:a flat display panel having a plurality of address electrodes and a plurality of scanning electrodes extending transversely to said address electrodes and disposed in confronting relation to said address electrodes, said address electrodes including first and second address electrodes disposed adjacent to each other; a scanning electrode driver successively supplying scanning pulses to said scanning electrodes at each one of scanning periods; address drivers supplying address pulses according to display data to said address electrodes in synchronism with said scanning periods, said address drivers comprising first and second address drivers connected to the first and second address electrodes, respectively, and when transferring from a scan operation for one scanning electrode to a next scan operation for another scanning electrode, the first address driver energizing the first address electrode such that a rising address pulse starts rising and the second address driver energizing the second address electrode such that a falling address pulse starts falling; and a control circuit controlling the first and second address drivers, with the first and second address drivers starting the rising and falling, respectively, at different predetermined times.
