Claim 5:
6. A method, comprising:
sending one first pulse of a tearing effect signal in each of a plurality of consecutive first preset times T1, wherein each first preset time T1 has a length of 1/f1, f1 is a first refresh rate of a display, each first pulse of the tearing effect signal indicates to a host to output a corresponding generated Nth frame of display data in a corresponding (N+1)th frame based on the respective first pulse of the tearing effect signal, and N is a positive integer;
sending S second pulses of the tearing effect signal when an Nth frame of display data is not received within a third preset time, wherein each pulse of the S second pulses of the tearing effect signal is used to prolong a duration of the Nth frame by a second preset time T2, and indicates to the host to output the generated Nth frame of display data in the (N+1)th frame based on an Sth second pulse of the tearing effect signal, S is a positive integer, (T1+T2)≤(1/f2), f2 is a second refresh rate of the display, and the first refresh rate is greater than the second refresh rate; and
attempting to receive the Nth frame of display data in the (N+1)th frame, and controlling, based on the Nth frame of display data when the Nth frame of display data is received, the display to display the received Nth frame of image.
