Patent ID: 7633480

Claim:
A driving circuit that drives an electro-optical device in which a gray-scale level of each of a plurality of electro-optical elements that correspond to a plurality of data lines is controlled on a basis of a voltage of a corresponding data line, the driving circuit comprising: a pulse output circuit that outputs a plurality of sampling pulses, each of the plurality of sampling pulses becoming an active level sequentially; a plurality of unit circuits each of which is supplied with a sampling pulse from the pulse output circuit; a signal line that is supplied with a gray-scale signal to sequentially designate the gray-scale level of each of the electro-optical elements; each of the plurality of unit circuits further including: a logical sum circuit that outputs a signal output corresponding to a logical sum between a sampling pulse input to the corresponding unit circuit and a sampling pulse input to a unit circuit located at a front stage of the corresponding unit circuit; a first switching element that samples the gray-scale signal supplied to the signal line in accordance with a sampling pulse output from the pulse output circuit; a second switching element that is inserted between the first switching element and the data line and that enters an off state until a predetermined period passes from a time when the first switching element starts a sampling operation, the second switching element being controlled so as to be turned on or turned off based on the signal output from the logical sum circuit; and a storage capacitor that holds a voltage of an output terminal of the second switching element.
