Atomic brothers draw lots

With a 2.8-inch MCU screen, when watching dynamic images, it is found that the image layering is very obvious. Check the data of 934 1 driver chip (the data of the chip does not indicate which commands can be used and which ones cannot be used). Tear effect command can read and write synchronously, and solve the problem of split screen. Excuse me, how to use this command specifically, and what is the connection relationship on the hardware? It seems that this 2.8-inch screen can't use this function.
