  • Switching method and switching device for display channel, display driving device and display device
    Patent number: 11574614
    Abstract: The present disclosure provides a method and device for switching a display channel, a display driving device and a display device. The method includes: sending a first switching signal to a write controller of a current display channel when a switching instruction for switching from the current display channel to a target display channel is received; acquiring a frame address in which final write operation of data is completed, and taking the frame address as a first address and a next frame address as a second address; sending a second switching signal to a write controller of the target display channel; and sending a third switching signal to a read controller.
