a second determining module, configured to determine target buffer data corresponding to the refresh coordinate in a first buffer, where the first buffer is used to store image data of a last displayed image;
a third determining module, configured to determine whether different data exists based on the target buffer data and the image to be refreshed;
and the storage module is used for storing the different data into a second buffer area under the condition that the different data exist, so that the screen acquires the different data from the second buffer area and displays the different data, wherein the second buffer area is used for storing data interacted with the screen.
9. An electronic device, comprising a memory and a processor, the memory having stored thereon a computer program which, when executed by the processor, performs a data processing method according to any one of claims 1 to 7.
10. A display device, comprising a screen and the electronic device according to claim 9, wherein the screen is in communication connection with the electronic device, and wherein the screen is refreshed according to different data when the different data is acquired.
11. A storage medium storing a computer program executable by one or more processors and operable to implement a data processing method as claimed in any one of claims 1 to 7.
