Problem solved by the technology

Mobile phones and similar communication devices are rapidly expanding in use and function. Such devices will soon accommodate more diverse services, such as Internet access, personal information management, facsimile, image messaging, andvideo conferencing, in addition to telephone communication. To accomplish this, there is a need to provide keypads, function buttons, and larger display screens that are compatible with more complex applications to which the mobile device will be adapted. Full function text keyboards, such as the standard QWERTY typing array of keys and buttons, are difficult to provide while maintaining the compact size required in the mobile device. An equally difficult problem is presented by the need for display screens that can display the vast amount of different information that will be accessible by these devices. Such devices on the market today are bulky and often require several accessories to obtain the full array of functions, e.g. a portable keyboard.

There is, therefore, a need to provide a simple and inexpensive full function mobile communications apparatus which can access many services through the use of a single device. It is also a purpose of this invention to provide a configuration of keypad, button deck, and rotatable display which provide a simple and easy-to-use user interface.

How the technology solves the problem

The frame, which has two opposite inner walls, is pivotally connected to the main module. A rotational axis is defined between the two inner walls. The screen is rotatable and mounted between the two inner walls of the frame, and the actuating device is operatively connected to the screen. The actuating device is capable of actuating the screen to rotate 180 degrees around the rotational axis in response to the movement of the display module from a closed position to an open position with respect to the main module.
