Abstract:
1. A driver circuit for driving an electro-optical device, the driver circuit comprising: a data signal output unit that outputs two kinds of output signal, one of the two kinds of output signal being data signals for displaying a picture, and the other of the two kinds of output signal being a first reference signal for adjusting a signal level of the data signals; a timing signal output unit that provides the data signal output unit with timing signals for specifying supply timings of the data signals, the timing signals including at least one enable signal; a detection unit that detects a signal level of the first reference signal provided by the data signal output unit; a switch unit that switches the data signals provided by the data signal output unit to the first reference signal before the detection unit detects the signal level; an adjustment unit that adjusts the signal level of the first reference signal provided by the data signal output unit so as to approach a standard value; and a signal control unit that controls the timing signal output unit to stop supply of the timing signals during the detection unit detecting the signal level of the first reference signal.
