PROBLEM TO BE SOLVED: To provide a method and a display system for updating image frames on a display screen of the display system without increasing consumption of processing electric power and of a memory. SOLUTION: In the system, image frames comprising a frame and line synchronization signal are transferred from a control system 104 to a display unit 116. The display unit comprises a display screen 122 for displaying image frames, a frame buffer 120 for buffering the image frames before they are transferred via a transfer bus 124 to the screen, and a display interface 112 for receiving image frames from the control system to the frame buffer. A frame and line synchronization signal are coupled to the control system from an image frame to be updated to the screen, and the control system is timed based on pulses comprised by the frame and line synchronization signal to input a new image frame to the frame buffer such that the new image frame is not stored onto the image frame being updated.
