Abstract:
A method of updating image frames on a screen of a display system, which comprises a control system and a display unit comprising a screen for displaying image frames, a transfer bus for transferring image frames to the screen, a frame buffer for buffering the image frames before the image frames are transferred via the transfer bus to the screen and for receiving image frames of the display interface from the control system to the frame buffer, the method comprising:transferring image frames comprising a frame synchronization signal and a line synchronization signal in the display system from the control system to the display unit; combining said frame synchronization signal and line synchronization signal to form one timing signal; coupling said timing signal to the control system; detecting said frame synchronization signal and line synchronization signal from said timing signal in the control system; and timing said control system on the basis of pulses comprised by said frame synchronization signal and line synchronization signal to input a new image frame to the frame buffer such that the new image frame is not stored onto said image frame to be updated to the screen.
