Patent ID: 6879312

Claim:
A display driver circuit which drives a plurality of signal electrodes of a display panel having a plurality of scan electrodes and the signal electrodes, the scan electrodes and the signal electrodes intersecting each other, comprising: a selector circuit which outputs one of a first voltage and a given fixed voltage, which is supplied to one of the scan electrodes, as a selected voltage, a multi-valued voltage select circuit which selects an output voltage from among a plurality of voltages including the selected voltage based on at least a polarity inversion signal, and a signal electrode driver circuit which drives the signal electrodes based on the output voltage, wherein, when performing display-OFF-control which shifts a pixel specified by one of the scan electrodes and one of the signal electrodes from a display-ON-state to a display-OFF-state, the selector circuit changes the selected voltage from the first voltage to the fixed voltage and outputs the selected voltage, and the multi-valued voltage select circuit fixedly selects the selected voltage after the selected voltage is changed to the fixed voltage by the selector circuit.
