Abstract
A driver that drives a segment electrode group of a liquid crystal panel includes a first segment drive circuit that drives a first segment electrode for displaying a warning light in the segment electrode group, and a second segment drive circuit that drives a second segment electrode for displaying a display item other than the warning light in the segment electrode group. The first segment drive circuit outputs a first drive signal for displaying the warning light displayed by the first segment electrode with a higher contrast than the display item displayed by the second segment electrode driven by a second drive signal of the second segment drive circuit.
