1. Field of the Invention
The present invention relates to the field of portable devices and more particularly to a hinged operated portable device including a plurality of display units.
2. Description of the Related Art
Generally, “portable communication devices” as the term is used herein refers to devices that allow for a form of communication, while the devices are being carried. Various applications or types of communications may be performed by the portable device. For example, voice communication, short message service, mobile banking, television (TV) watching, on-line game service, and on-demand video service are communications or applications that may be provided to users using portable communication devices.
The portable communication devices may include devices such as a hand-held phone (HHP), a cordless telephone (CT-)2 cellular phone, a digital phone, a personal communications systems (PCS) phone, and a personal digital assistant (PDA) and are sorted into various types according to their appearances. For example, wireless terminals are sorted into a bar type, a flip type, a folder type, a sliding type, and a pop-up type according to their appearances. The above-mentioned portable communication devices always include an antenna apparatus, a data input/output device, and a data transceiver. For the data output device, a display unit is generally used. Recently, some terminals include a touch screen that allow the user to input data by touching a display screen on the display unit
However, a display unit of a conventional portable communication device generally has a screen size of about 320×240 pixels, and such a small screen size of the display unit is too small for a user to comfortably access a public network, such as the Internet, or watch television or operate an on-line game service, or watch a multimedia presentation (e.g., moving or motion pictures)
In addition, the conventional portable communication device needs a separate cradling device that may hold the device in place. Generally, the cradling device allows the user to position the portable device at an angle convenient for viewing. Otherwise, it is inconvenient for the user to see the (display) screen of the display unit that is placed on a desk without a cradling device.
As a result, there is a need for a portable communication device in which a plurality of display units may be used together or positioned to allow convenient viewing of the display screen.
