Abstract
Display data Dto Dn are latched by a data latch, and are supplied to AND gates which are gate-controlled by a blanking signal/BLK. Output signals from the AND gates are delayed by delay circuits having different time delays of τto τn, and then supplied to drivers. Subsequently, the output signals are supplied to a display device as driving signals Qto Qn. The timings of changes of signals Sto Sn supplied to the drivers are distributed by the delay circuits, so that the timings of currents ito in flowing through the drivers are also distributed. Accordingly, a sum Σi of the currents ito in changes gradually over time, thereby decreasing the peak current.
