Controlling complementary bistable and refresh-based displays
An electronic device includes complementary dual displays, which enable sending a video signal to a first display, wherein the first display is a refresh-based, high frame rate display; displaying the video signal on the first display; and printing a frame of the video signal to a second display, wherein the second display is a bistable, low frame rate display, the printing including, loading a portion of a current frame of the video signal into a frame buffer, and displaying the current frame of the video signal to a second display, such that a bistable static image is displayed on the second display. The device may be switched among read, extend, and navigate modes, which enable different transitions of content between the two screens by a common application, such as a browser application.
