Description

Multi-Function Mobile Phone With Two Displays}

The present invention relates to a multi-function mobile phone terminal based on a dual display, and more particularly, a key input unit consisting of a small key module and a small number of function keys to perform numeric input, character input, and other basic functions of a mobile phone, and The present invention relates to a mobile telephone terminal having two displays together to implement various communication and entertainment functions.

In general, only one display of a mobile telephone terminal is provided at the top of the terminal in the case of an integrated type, and in a terminal folder (cover) of the folder type. When two displays are used in a mobile phone, a so-called dual folder is used. In addition to the primary display installed inside a folder, a secondary display is installed outside the folder, thereby allowing the user to display the date and time without opening the phone. It provides simple information such as communication sensitivity, battery level, and notification of receipt of a text message.

In addition, a conventional clamshell terminal has almost ten number / signal keys and several function keys inside its main body (except for a folder, in the case of a folder type). That is, inside the main body of the terminal, about 20 keys exist in various positions and angles, and are solely responsible for the input function.

For this reason, it is impossible to expand the size of the display inside the terminal without expanding the external size of the terminal using the existing terminal configuration. It was also nearly impossible for a user to do two or more tasks at the same time. Even if two tasks were attempted at the same time, the process of presenting each piece of information to the user had to either divide the limited display space within the only existing terminal folder or alternately show each piece of information within that space. .

In the existing terminal, installing another display inside the main body of the terminal was virtually impossible due to the physical space occupied by about 20 keys necessary for operating the terminal. As a result, the display of the terminal was inevitably arranged to be limited to the folder portion of the terminal.

The present invention has been made in view of the problems of the prior art, the purpose of which is to remove the dozen keys which are located in the main body of the conventional mobile phone terminal and performing functions such as number and letter input, instead the function A small key module and a few function keys are used to perform relatively small spaces, and a second display is installed in the surplus space at the bottom of the terminal (in the case of a folder type, inside the main body), thereby improving utilization of the mobile phone terminal. It is to widen.

The multi-function mobile phone terminal equipped with the dual display according to the present invention includes two displays, one at the top of the terminal (in the case of a folder type) and one at the bottom (in the case of a folder type). SMS, mobile messenger, video call, video chat, TV and VOD, games, jukeboxes, navigation systems, web browsers, etc., the main content of each function is displayed on the primary display, and the secondary content is displayed on the secondary display. Or, if two tasks are performed simultaneously, each function is shown separately on a separate display, thereby enhancing the functionality and utilization of the mobile phone terminal.
