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.
1. A system of a first electronic device for managing content navigation between the first electronic device including a first display and a second electronic device including a second display, the system comprising a non-transitory computer-readable storage medium containing a navigation operative of the first electronic device that when executed by one or more processors performs steps comprising:
rendering a digital content from an encoded format into a first static image starting at a first anchor point and with an optimized resolution and screen size associated with the first display of the first display device, and displaying at least a portion of the first static image at the first display device,
rendering the digital content from the encoded format into a second static image starting at the same rendering position of the digital content as the rendering of the first static image and including the first anchor point, wherein the second static image with an optimized resolution and screen size associated with the second display of the second electronic device;
generating, at the first electronic device, a first output to the second display device, the first output including information representing at least a portion of the second static image; and the at least the portion of the second static image is a first intended display by the first device operative to be displayed at the second device based on the first output;
receiving an input from a user at the first device navigating the digital content to a new intermediate position to be displayed on the first display;
establishing a second anchor point of the digital content corresponding to the new intermediate position of the user navigation at the first display and display at least a portion of an updated static image of the first static image to the first display based on the new intermediate position; and
generating, at the first electronic device, a second output to the second electronic device, the second output including information representing at least a portion of an updated static image of the second static image based on the second anchor point; and the at least the portion of the updated image of the second static image is a second intended display by the first device operative to be displayed at the second device based on the second output.
2. The system of claim 1 , wherein the first electronic device is a mobile phone with a touch screen display with a graphical user interface.
3. The system of claim 1 , wherein the first electronic device generates information representing intended displays to be viewed by the user at the first electronic device and the second electronic device.
4. The system of claim 1 , wherein the input is a graphical user interface input on a touch screen of the first display of the first electronic device to move the first anchor point to the second anchor point.
