OUTPUT CONTROL CIRCUIT, DRIVING CIRCUIT, ELECTROOPTICAL DEVICE, AND ELECTRONIC INSTRUMENT

摘要

PURPOSE: To eliminate the duplication of a sampling signal in an output control circuit and a driving circuit used with a transfer means applying cascade connection to a plurality of unit circuits successively shifting a start pulse by syncronizing with a clock signal. CONSTITUTION: A data line driving circuit 200 is provided with a shift register section 210 applying the cascade connection to each shift register unit circuit Ua1 to Uan+2 and an output signal control section 220 consisting of each arithmetic unit circuit Ub1 to Ubn+1. NAND circuits 514 limit the effective period of time of the negative sampling signal based on the output signals of NAND circuits 511 in the next stage arithmetic unit circuit.
