Other objects, advantages and efficacy of the present invention will be described in detail below taken from the preferred embodiments with reference to the accompanying drawings, in which:
a) and 1(b) are diagrams illustrating a first embodiment of the electronic device according to the present invention;
a) and 2(b) are diagrams illustrating a second embodiment of the electronic device according to the present invention;
a) and 3 (b) are diagrams illustrating a third embodiment according to the present invention;
The present invention will now be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purposes of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.
An unstable display refers to a displaying device that continues displaying contents under condition that electric power is continuously supplying thereto. Once the electric power is disconnected, the contents showing on the screen of the unstable display disappears. A bi-stable display refers a displaying device that is capable to display contents on the screen for quite a period while even electric power does not supply thereto. Once the electric power is disconnected the contents showing on the screen of the unstable display disappears. For a bi-stable display, the electric power is just used for driving the electrophoresis particles so as to update the displaying contents. For a bi-stable display, when the electric power is shut down, the displaying contents stays in the last updated contents. Usually, a bi-stable display is preferably capable to display an unvaried contents for lasting almost one month, which is suitable for a demand displaying a static contents or an application occasion that needs a long-term demonstration.
Typically, a bi-stable display is preferably a bi-stable liquid crystal display (LCD), a micro-electro-mechanical system (MEMS) display, an electro-phoretic display (EPD), a reflective-display or an electronic paper. A stable display is preferably an unstable LCD, an electrowetting display or a plasma display. At the same time, the mentioned bi-stable display and the unstable display preferably a touch-based display having a touch panel disposed thereon, a flexible display or a soft display.

A host 101 of the electronic device 100 has a first side 102 and a second side 103 opposite to the first side 102. An unstable display 1 is disposed on the first side 102 and a bi-stable display 2 is disposed on the second side 103. The unstable display 1 disposed on the first side 102 are commonly suitable for displaying a dynamic contents and the bi-stable display 2 disposed on the second side 103 are commonly suitable for displaying a static contents. For instance, while the electronic device 100 is preferably a GPS, the unstable display 1 on the first side 102 is suitable for displaying a digital map having much dynamic displaying contents since the map is dynamically altered in response to movement of a user. The bi-stable display 2 on the second side 103 is used for displaying for instance an email or an e-book having much static displaying contents. Specifically, a user can directly utilize such GPS having two screens to obtain a real-time geographic road information by a LCD on the first side and read e-mail or e-book by the EPD on the second side simultaneously. Additionally, the electronic device 100 could be preferably a handheld digital television player, where a LCD on front side is used for playing TV program and an EPD on back side is used for displaying e-mail or e-book simultaneously.
The host 101 of the electronic device 100 further includes a switch 106 for switching the unstable display 1 and the bi-stable display 2 to operate between a synchronization mode and a non-synchronization mode. While a synchronization mode is switched, the displaying contents on the respective unstable display 1 and bi-stable display 2 are associated to become an integration. While a non-synchronization mode is switched, the displaying contents on the respective unstable display 1 and bi-stable display 2 are irrelevant. It is noted that the bi-stable display 2 can be disposed on the lateral side 104 of the host 101. Several function components such as, an expansion slot 105 and an ear phone socket 107, are preferably further disposed on the host 101.
