Claim:
A method for controlling complementary dual displays of an electronic device, the method comprising: executing an application on the electronic device, the application for viewing one or more pages of information on the device; generating a video signal by the application, wherein the video signal is part of a user interface for interacting with one or more pages of information displayed on the device; sending the video signal to a refresh-based high frame rate (REHF) display; displaying the video signal on the REHF display; generating a first frame by the application, the first frame comprising at least a portion of a first page of information; writing the first frame to a frame buffer associated with a bistable low frame rate (BILF) display; displaying the first frame from the frame buffer on the BILF display; receiving a user selection via the user interface displayed on the REHF display, the user selection to display an intermediate location within the first page of information currently displayed on the BILF display; generating a second frame based on the user selection, the second frame different from the first frame and comprising at least a portion of the first page of information corresponding to the intermediate location; writing the second frame to the frame buffer associated with the BILF display; displaying the second frame from the frame buffer on the BILF display; generating a second video signal by the application, wherein the second video signal comprises a feedback signal to update the REHF display and is generated based at least in part on the second frame, the feedback signal indicative of the display of the second frame on the BILF display; and sending the second video signal to the REHF display to update the REHF display.
