Patent ID: 7443376

Claim:
A scan electrode driving circuit, which supplies a scanning signal to each of a plurality of scan electrodes of a display panel, comprising: a scanning signal generating circuit; and M (M is an integer larger than 1) output circuits connected to said scanning signal generating circuit, wherein said scanning signal generating circuit generates a first to N-th (N is an integer larger than 1) output signals in order, and outputs each of said first to N-th output signals repeatedly to each of said M output circuits, wherein said scanning signal generating circuit counts a number of repeat times, and outputs a count data signal indicative of said number of repeat times to each of said M output circuits, wherein, when said count data signal indicates a value k (k is an integer in a range from 0 to M- 1), k-th output circuit of said M output circuits converts said first to N-th output signals to a first to N-th scanning signals, respectively, and outputs said first to N-th scanning signals to N scan electrodes of said plurality of scan electrodes in order, respectively.
