Abstract:
In an embodiment, a sampling signal to each data signal line is generated by using an output signal outputted from each flip-flop, and a precharge signal by which the data signal line to which the sampling signal is to be outputted is precharged is generated by using an output signal outputted from an output terminal of the flip-flop. Further, by providing a NOR circuit, an active period of the precharge signal and an active period of the sampling signal are prevented from overlapping each other. With this, in an embodiment of a display device driving circuit, including a precharge circuit, which causes a precharge power supply to precharge signal supply lines, the number of shift registers and the size of a circuit can be reduced.
