摘要:
Current approaches to paperless books use single screen laptop computers or electronic paper display (EPD)-based book readers. Laptop computers consume too much power and cannot be used for extended periods of time, such as an entire school day, without recharging its battery. EPD devices are limited in functionality due to their slow refresh rate and grey-scale only images. An embodiment of the present invention integrates bi-stable display technology and refresh display technology into a single device and manages the use of these technologies to achieve power savings while providing a rich set of display functionalities to support user interaction with content in a synergistic manner. The power savings functionality enables the device to have a battery operating life between charges of many hours of operation, such as eight hours or more, while the display functionality enables users to access, display, and interact with content in ways users have become accustomed and in ways not before possible.
