Abstract:
A method for driving a semiconductor device comprising:inputting a signal to a first level shifter circuit in a source signal line side driving circuit; increasing a voltage of the signal, by the first level shifter circuit, to a first voltage amplitude level at which it is sufficient for a shift register circuit to operate; inputting the increased signal to the shift register circuit; creating a timing signal, by the shift register circuit, based on the signal input from the first level shifter circuit; inputting the timing signal to a second level shifter circuit; increasing a voltage amplitude level of the timing signal by the second level shifter circuit; inputting the increased timing signal to a sampling circuit; and sampling an image signal, by the sampling circuit, in accordance with the increased timing signal; and supplying the sampled signal to source signal lines connected to the source signal line side driving circuit.
