Display control method, pixel driving circuit, driving chip, controller and device

According to the display control method, the pixel driving circuit, the driving chip, the controller and the equipment provided by the invention, the difference data of the current frame image and the adjacent previous frame image and the pixel position of the difference data in the image are acquired, and then the pixel position of the current frame image is calculated according to the difference data and the pixel position of the difference data in the image. And generating a target row and column control signal, and updating the to-be-updated data in the current frame of image according to the target row and column control signal, so that local image refreshing of the display screen can be realized, and the method and the device can enable an area in which the image content is not changed not to be transmitted, maintain original data, improve the bandwidth utilization rate, and improve the user experience. In addition, under the condition that an interface is not changed, the amount of transmitted data bec
