As one of the portable devices combined as described above, a device in which the portable telephone and the portable information terminal are combined is referred to as "portable composite wireless terminal" in the present invention. In general, portable telephones are used for voice calls, data and video communications, and portable information terminals can use various applications as portable devices such as PDAs (Personal Digital Assistants) and electronic organizers.

According to the degree of complexity, the portable hybrid wireless terminal combines some of the functions of the portable information terminal with the functions of the portable telephone, that is, the form of a smart phone, and the functions of the portable telephone in all the functions of the portable information terminal. There is a form of realizing a data communication function. One of the problems in designing such a composite wireless terminal is the information input / output method. It is necessary to provide a large screen display for displaying an application or information while maintaining the form factor of the portable telephone.

For this purpose, some devices enlarge the display window of the telephone and share the display for the telephone and the display for the application. It places a touch screen input / output device that provides a large screen on the front of the device, and enables all applications to use the application for phone functions and information processing with a pen or finger on the screen display. This is how you design. In general, a touch screen input / output device is an information input / output device employed in most information terminals. The touch screen input / output device has a structure in which a touch-sensitive panel (TSP) for inputting information is covered on a liquid crystal display (LCD) panel for displaying a screen. However, the method of sharing a display device for a phone and a display device for an application as described above has been inconvenient, such as a lack of touch or confidence that a user presses, compared to a physical button used for a key or information input in a portable phone. In addition, in order to input various data while executing an application, a screen keyboard or a command icon for other input should be placed on a part of the screen display device. Such a design is not only inconvenient to use a physical button but also has a spatial limitation that the screen keyboard and the like cover part of the screen when the screen keyboard and the like are displayed for input.

In contrast, the device is designed to be foldable, leaving the phone appearance with the phone display on the front and exterior, and a large display and keyboard and pen interface on the inside that are exposed when opened. The front part of the device has the same display window for the phone as the mobile phone, and the physical buttons are arranged to use the same as the mobile phone, and a separate large screen display for running the application is exposed so that the phone is opened when opened. It's a way to position the keyboard or design it to allow pen input. In this case, placing a physical keyboard is as thick as the keyboard space and thus bulkier. In addition, since the large-screen display device is spaced apart from the telephone display window on the front side so that it cannot be seen at a glance, it is difficult to configure an application controlling the operation of the phone together with the front-panel buttons. And products configured without a keyboard also use a screen keyboard for data entry, which results in a smaller screen for the application.

As described above, the information input / output devices employed in the conventional portable composite wireless terminal are inconvenient for the user to use, and the design is difficult or bulky, and the screen of the application is reduced when using a screen keyboard.
