Abstract: A position data exchange system comprises first and second mobile communication devices. The first communication device retrieves current coordinates of itself from a Global Positioning System (GPS) receiver and transmits the coordinates through a wireless communication channel from which the second communication device receives the coordinates. The second communication device displays data concerning the current location of the first communication device according to the coordinates and further provides navigation.

Abstract: A portable communication apparatus equipped with basic communication functions and game functions include a first body and a second body. The first body has a bi-directional axle, a display screen and a first keyboard area on the top surface. The second body is hinged on the bi-directional axle, and includes a second keyboard area on the top surface thereof and a third keyboard area on the back surface. The second body is turnable around the bi-directional axle relative to the first body to generate movements around two axes, to turn the second keyboard area or the third keyboard area, to face the display screen and to fold over the first body. When the second body is turned relative to the first body, the image displayed on the display screen also is turned to a selected angle.

Abstract: A mobile phone includes an antenna assembly having first, second, third and fourth antenna metal strips. The first, second, third and fourth antenna metal strips are respectively compatible to the digital phone system, GSM (Global Sim Mobile), GPS (Global Positioning System), WLAN (Wireless Local Area Network).

Abstract: An integrated double-sided organic light-emitting display includes a substrate on which a main-panel, a sub-panel, and a control module are installed. The main-panel is used for generating a main-image light, which progresses along a first display direction. The sub-panel is used for generating a sub-image light, which progresses along a second display direction, and the first display direction and the second display direction are mutually reversed directions in free space. The control module is electrically connected to the main-panel and the sub-panel for controlling operations of the main-panel and the sub-panel.

Abstract: A folder-style mobile phone having a rotatable processing module includes a first casing having a first hinge, a second casing having a second hinge, a processing module, and a rotatable signal-processing module. The processing module is provided in the first casing for processing data. The rotatable signal-processing module, provided in the second casing, includes a plug arranged in the second hinge to connect to a wire provided in the first hinge, an antenna for receiving and transmitting radio frequency signals, and a wireless module electrically connected between the plug and the antenna for transforming signals from the processing module into corresponding radio frequency signals to the antenna and transforming signals from the antenna into corresponding signals to the processing module.

Abstract: A method of changing light emitted from a mobile phone. The mobile phone includes a circuit board, a plurality of buttons set on the circuit board forming a button area on the mobile phone, and a plurality of light sources set on the circuit board. The method includes providing a casing, adding fluorescent material onto the casing, positioning the casing with the fluorescent material on a side of the circuit board with the plurality of light sources, and triggering the plurality of light sources such that light passing through the casing is different from backlight originally emitted from the plurality of light sources.
