ABSTRACT:
A matrix electrode structural display element driving unit is provided with a display panel in which electrodes are arranged in a matrix pattern, and a signal electrode driving circuit and a scanning electrode driving circuit for driving the display panel. A latch pulse signal LPX to be inputted to the signal electrode driving circuit and a latch pulse signal LPY to be inputted to the scanning electrode driving circuit are used as signals with different waveforms. Since a conventional general driving IC is used, a unit, where a level of an applied voltage to a display element is changed twice during one selecting period, can be obtained at a low price.
