Abstract: An expandable keyboard device includes a keyboard, and a supporting assembly having interconnected first and second panels. The second panel is adapted to connect with an electronic device. The supporting assembly is movable relative to the keyboard between an unfolded state, where the first panel extends upwardly relative to the keyboard for supporting the electronic device above the keyboard, and a folded state, where the second panel along with the electronic device cover the keyboard. An electrical connector is disposed in the housing for electrical connection with the electronic device. A connecting unit interconnects the supporting assembly and the keyboard.

Abstract: A flexible electronic device can be operated in multiple operation modes. The flexible electronic device mainly includes a substrate, a flexible display module, at least one folding device, a button module, and a processing unit. The flexible display module is located above the substrate, and the at least one folding device is used for folding the display. When the display is unfolded, a main display is launched on the display. When the display is folded, the main display can be divided into a plurality of sub-display zones such that images or graphics can be displayed on one of the sub-display zones. The button module is located on one of the sub-display zones. The processing unit is electronically connected to the button module in order to operate the flexible electronic device.

Abstract: A method for P2P signal synchronization and P2P wireless communication device and system using the same. The method includes the following steps. A first P2P wireless communication device having an effective range acts as a master device. At least one second P2P wireless communication device located in the effective range is paired and connected with the first P2P wireless communication device. When the first P2P wireless communication device acts as the master device, the first P2P wireless communication device broadcasts a synchronization signal. After the at least one second P2P wireless communication device receives the synchronization signal, at least one second P2P wireless communication device is switched to the master device and broadcasts the synchronization signal.

Abstract: Disclosed herein is an electronic paper display. The electronic paper display includes an electronic paper panel, a light guide structure, and a light source. The light guide structure is disposed over the electronic paper panel for reflecting and scattering light. The light source that is disposed on one lateral side of the light guide structure is operable to generate light, wherein the light generated by the light source, after being reflected and scattered by the light guide, illuminates the electronic paper panel.

Abstract: A driving device for a portable electronic display device, capable of adapting to a holding direction of a user and driving the portable electronic display device, includes a plurality of sensing units deposited at edges of the portable electronic display device, for sensing a holding status of the user, to generate a plurality of sensing results, and a control module for determining the holding direction of the user according to the plurality of sensing results, and adjusting operations of the portable electronic display device accordingly.
