Abstract
A simultaneous precharge type display device source driver includes supply control circuits each of which is provided on each of source bus lines. Each of the supply control circuits receives (a) a precharge control signal for precharging each of the source bus line and (b) a sampling control signal for writing data, which should be written on pixels, onto the source bus line. The one of two switches turns ON in response to the precharge control signal and the sampling control signal. The other of the switches turns ON in response to the sampling control signal. In the sampling operation, both the switches are turned ON so as to quicken the writing operation. In the precharge operation, the other switch does not operate, so that it is possible to reduce the power consumption.
