Abstract
A refresh control method and apparatus of a display device are disclosed, where the method includes: (201) periodically generating, a first refresh signal, and outputting an image frame for display that is stored in a frame buffer to a display panel; and (202) generating, a second refresh signal when determining that the image frame for display that is stored in the frame buffer changes, and outputting the image frame for display that is stored in the frame buffer to the display panel. A generation frequency of the second refresh signal is far less than a frequency required to ensure timely display of an image frame. In addition, an operation of refreshing an image frame is triggered by using an event, which may ensure timely display of the image frame, and avoid an unnecessary refresh operation, so as to reduce system resource consumption and memory consumption.
