ABSTRACT:
A display driver circuit (100) includes N scanning drivers (150) for driving a scanning set of display electrodes of a display panel (160) with a set of scanning signals (155), P information drivers (130) for driving an information set of display electrodes of the display panel (160) with a set of information signals (135), and a control section (120) having a first mode and a second mode. In the first mode the control section (120) controls the N scanning drivers (150) to generate N different scanning signals (155). In the second mode the control section controls the N scanning drivers (150) to generate a common scanning signal by S of the scanning drivers (156) and N-S different scanning signals by N-S drivers of the scanning drivers (157), wherein N, P and S are positive integers.
