Claim 2:
3. The display apparatus according to claim 1, wherein the plurality of sub-pixels include a plurality of red sub-pixels, a plurality of green sub-pixels, and a plurality of blue sub-pixels; and
the emission time control chip is configured to: transmit at least one first emission time control signal to the plurality of red sub-pixels through a respective group of output terminals; transmit at least one second emission time control signal to the plurality of green sub-pixels through a respective group of output terminals; and transmit at least one third emission time control signal to the plurality of blue sub-pixels through a respective group of output terminals; wherein
in a frame, the first emission time control signal, the second emission time control signal, and the third emission time control signal have a same number of periods, and durations of the periods are equal; in each period, a phase of a first level of the second emission time control signal lags behind a phase of a first level of the first emission time control signal by a first angle, and a phase of a first level of the third emission time control signal lags behind the phase of the first level of the second emission time control signal by a second angle; and the first level is a level that enables the emission time control circuit to stop transmitting the driving signal.
