Driver circuit, electro-optical device, electronic instrument, and drive method

摘要

A driver circuit includes a first output buffer BUF₁ which drives a data line of an electro-optical device based on grayscale data, and a first precharge circuit PC₁ which precharges an output line of the first output buffer BUF₁. The first precharge circuit PC₁ supplies a first precharge voltage to the output line in a first precharge period in a drive period. In a second precharge period after the first precharge period, the first precharge circuit PC₁ supplies a high-potential-side power supply voltage, a low-potential-side power supply voltage, or the first precharge voltage to the output line based on higher-order two-bit data of the grayscale data. The first output buffer BUF₁ drives the output line based on a grayscale voltage corresponding to the grayscale data after the second precharge period.
