Patent ID: 7277091

Claim:
A driving circuit for an electro-optical panel, including: a substrate; pixel electrodes formed on the substrate; switching elements to switch and control the pixel electrodes; data lines to supply an image signal to the pixel electrodes through the switching elements; a data-line driving circuit including a shift register circuit that sequentially outputs transmission signals; a sampling circuit that samples the image signal using a sequentially-output n-th (n is a natural number greater than or equal to 2) transmission signal as a sampling-circuit driving signal, and writes the sampled image signals to the data lines; a precharge circuit that writes a precharge signal of a predetermined potential to the data lines using the sequentially-output (n−1)-th transmission signal as a precharge-circuit driving signal prior to supplying the image signal to the data lines; and a period when the precharge signal is written to the data lines in response to the (n−1)-th transmission signal and a period when the image signal is written to the data lines in response to the n-th transmission signal not overlapping with each other on the time axis.
