Abstract
A scan electrode driving circuit has a scanning signal generating circuit, and M (M≧2) output circuits connected to the scanning signal generating circuit. The scanning signal generating circuit generates a first to N-th (N≧2) output signals in order, and outputs them repeatedly to the M output circuits. Also, the scanning signal generating circuit counts the number of repeat times, and outputs a count data signal indicative of the number of repeat times to the M output circuits. When the count data signal indicates a value k (0≦k≦M−1), k-th output circuit of the M output circuits converts the first to N-th output signals to a first to N-th scanning signals, respectively, and outputs them to N scan electrodes of a display panel in order, respectively.
