A display apparatus includes a control circuit for outputting a timing signal for determining a predetermined time period and a clock signal counted to determine the length of a modulation signal. The display apparatus is capable of switching between a first state in which a first timing signal and a first clock signal are output, and a second state in which a second timing signal and a second clock signal are output. The first time period is shorter than the second time period, wherein the first time period is the predetermined time period determined by the first timing signal and the second time period is the predetermined time period determined by the second timing signal. The frequency of the first clock signal is higher than the frequency of the second clock signal.
