Display driving method and device, integrated circuit chip and terminal

The invention provides a display driving method and device, an integrated circuit chip and a terminal, and the method comprises the steps: a DDIC chip can determine a vertical edge corresponding to a current image frame according to the current image transmission speed of an AP when receiving the current image frame, and drives a display screen to display the current image frame based on the determined vertical edge. Therefore, the vertical edge corresponding to the current image frame is determined in real time according to the current image transmission speed of the AP, so that the tearing phenomenon occurring in the process of driving the display screen with the variable refresh rate is effectively avoided. 本公开提出一种显示驱动的方法、装置集成电路芯片及终端，其中，DDIC芯片在接收到当前图像帧时，即可根据AP的当前图像传输速度，确定当前图像帧对应的垂直沿，进而基于确定的垂直沿，驱动显示屏显示当前图像帧。由此，通过根据AP的当前图像传输速度实时的确定当前图像帧对应的垂直沿，从而有效避免了在驱动刷新率可变的显示屏的过程中，出现的撕裂现象。
