Display channel switching method and module, display driving device and display equipment

The invention provides a display channel switching method, which comprises the following steps of: when a switching instruction of switching from a current display channel to a target display channelis received, sending a first switching signal to a write control module corresponding to the current display channel so as to control the write control module corresponding to the current display channel to stop writing image data; obtaining a frame address which finally completes data writing in the memory, taking the frame address as a first address, and taking the next frame address as a secondaddress; sending a second switching signal to a write control module corresponding to the target display channel, so that the write control module writes each frame of image data of the target display channel into each frame address in sequence from the second address; and sending a third switching signal to the reading control module, so that the reading control module sequentially reads the image data in each frame addr
