5. The method according to claim 3 , wherein the first frame-rate processing format is a full frame-rate processing format; and the second frame-rate processing format is a half frame-rate processing format.

6. The method according to claim 5 , wherein converting the frame rate of the touch data in the data buffer based on the target frame-rate processing format comprises:

locking a frame line of the touch data in the data buffer, in response to the target frame-rate processing format being the first frame-rate processing format; or

performing frequency-multiplied reading on the touch data in the data buffer, in response to the target frame-rate processing format being the second frame-rate processing format.

7. The method according to claim 6 , wherein locking the frame line for the touch data in the data buffer comprises:

locking a line clock signal controlling the touch data in the data buffer, and locking a frame clock signal controlling the touch data in the data buffer.

8. The method according to claim 6 , wherein performing the frequency-multiplied reading on the touch data in the data buffer comprises:

multiplying a frequency of a line clock signal controlling the touch data in the data buffer, and multiplying a frequency of a frame clock signal controlling the touch data in the data buffer.

9. The method according to claim 1 , wherein after converting the frame rate of the touch data in the data buffer based on the target frame-rate processing format, the method further comprises: spreading a frequency of a video signal output based on the touch data.

10. The method according to claim 8 , wherein the format acquisition request further carries a request priority of the first frame-rate processing format and a request priority of the second frame-rate processing format, and the request priority of the first frame-rate processing format is higher than the request priority of the second frame-rate processing format;

the received target frame-rate processing format is the second frame-rate processing format if the frame-rate processing format supported by the terminal device comprises the second frame-rate processing format of the first frame-rate processing format and the second frame-rate processing format; or

the received target frame-rate processing format is the first frame-rate processing format if the frame-rate processing format supported by the terminal device comprises the first frame-rate processing format and the second frame-rate processing format;

locking the frame line of the touch data in the data buffer comprises:

locking a line clock signal controlling the touch data in the data buffer, and locking a frame clock signal controlling the touch data in the data buffer;
