Claim 11:
12. A driving method of the display apparatus according to claim 1, the driving method comprising: in a frame:
transmitting, by pixel driving circuits, driving signals to light emitting devices of the plurality of sub-pixels according to image data of an image to be displayed; and
transmitting, by the emission time control chip, the emission time control signals to the emission time control circuits of the plurality of sub-pixels, so as to control durations of transmission of the driving signals to the light emitting devices of the plurality of sub-pixels; wherein the emission time control signals are pulse width modulation signals; wherein
the emission time control signals each have first levels and second levels that are alternately arranged, the first levels are each a level that enables the emission time control circuit to stop transmitting the driving signal, and the second levels are each a level that enables the emission time control circuit to transmit the driving signal; and the plurality of sub-pixels include sub-pixels of three colors; and
transmitting, by the emission time control chip, the emission time control signals to the emission time control circuits of the plurality of sub-pixels includes:
transmitting, by the emission time control chip, the emission time control signals with different phases to the sub-pixels of different colors.
