Description

Slide mobile phone terminal or portable electronic device with keyboard {the Dual Slide Phone / PDA / Smart Phone}

Mobile phone terminals have continued to evolve and have reached their present form. Starting from the early bar terminals, there are a variety of forms, such as flip type, folding type, swing type, and slide type, which are most commonly used. Along with the change in form, it is a functional addition. Currently, mobile phones go beyond the functions of general telephone calls, and the functions of data search, games, VOD, web surfing, camera, MP3 etc. are continuously added. Is becoming the center of Recently, the dissemination of a new concept mobile phone, which combines the functions of a PDA and a mobile phone terminal, is becoming visible, proving the current status of becoming the center of digital media. However, there are two limitations to the current leap to the central digital media device.

First, there is a lack of horizontal display support.

Second, the input method is inconvenient.

An object of the present invention is to develop a new mobile phone form factor that is familiar to the general public and can solve all the above-mentioned limitations. It is to be noted that the form factor proposed by the present invention can be applied to other portable devices such as PDAs, smartphones as well as general mobile phone types.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, numerous specific details are set forth in order to provide a more thorough understanding of the present invention, such as specific structures or shapes, process flows, screen examples, and the like. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted. In the following description, it should be noted that the same elements in the drawings represent the same reference signs wherever possible.

1 to 5 are perspective views showing a mobile phone terminal according to an embodiment of the present invention. 1 is a perspective view showing a form folded when carrying a normal, Figure 2 is a perspective view showing a mobile phone terminal when using a general call. 3 is a perspective view of using a keyboard, and FIG. 4 is a perspective view of utilizing a game machine by fixing a joy pad instead of using a keyboard. Fig. 5 is a perspective view showing the shape of a mobile phone when all the slide parts are deployed.

As shown in Figures 1 to 5, the present invention is largely divided into three main body parts: the output main body 11, the input main body 12, the keyboard main body (13). The three main bodies are connected by two slide hinges, and the screen reference (long side horizontally, short side vertically), which is called X slide hinge 81, moves horizontally to the input body 12 and the keyboard body 13. Connect the keyboard to slide freely in the direction of the screen reference. The Y slide hinge 82 moves vertically with respect to the screen, and connects the keyboard main body 13 and the output main body 11. Thus, the two slide hinges move perpendicularly to each other so that they are not affected by each other's movements.

The output body 11 is composed of a speaker 47a and a screen 48 in appearance. Most of the slide-type mobile phone terminals currently on the market are different from the present invention, in which the direction keys 41 are mounted to the output body 11 specified in this document. According to the present invention, when the direction key 41 is completely mounted as shown in FIG. 1 by attaching the direction key 41 to the input body 12, the size of the direction key 41 can be drastically reduced or a wider screen 48 can be secured.

In the input body 12, the directional key 41, the other keypad 40, the side button 42, the screen rotation button (not shown), the battery 1000, the microphone 47b, etc. are located. The input body 12 is connected to the keyboard body 13 and the X slide hinge 81. Thus, when the X slide hinge 81 is moved in the closed state as shown in FIG. 1, the shape as shown in FIG. In the case of the screen rotation button, the screen is turned on in the fully closed state, and the screen is turned from horizontal to vertical and from vertical to horizontal without the hinge movement when the screen is turned on.

The keyboard body 13 is equipped with a keyboard 43 or a joypad component game direction key 45 and a command button 46 for a game. The keyboard main body 13 is connected to the output main body 11 by the Y slide hinge 82, and the input main body 12 by the X slide hinge 81. Of course, it is not possible to mount the keyboard 43 and the joypad component at the same time, so one of the two must be selected. The present invention adds a keyboard main body 13 between the output main body and the input main body of a general slide-type mobile phone by using a keyboard 43 or a joy pad component, and makes the character input method much more familiar and faster when inputting a game. When doing so, it provides a comfortable horizontal display and grip like a general game console, so that the user can use it easily.

 FIG. 7 is a block diagram of a portable composite wireless terminal 10 according to an exemplary embodiment of the present invention. The keypad 45, the microphone 47b, the speaker 47a, and the like are shown in FIGS. 1 to 4. In the embodiment of the present invention, the control unit 100, the memory 110, the interface 112, the duplexer, the RF (Radio Frequency) transmission and reception unit 114, 118, and the codec (Coder-Decoder) 120 ) Is embedded in the input body (12). In FIG. 7, the antenna 24, the interface 112, the RF transmitter / receiver 114, 118, and the duplexer 116 are blocks corresponding to a typical portable telephone. The duplexer 116 separates transmission and reception signals transmitted and received through the antenna 24. The RF transmitter 114 modulates a signal to be transmitted from the controller 100 through the interface 112 to transmit an RF signal through the duplexer 116 and the antenna 24, and the RF receiver 118 is an antenna ( 24) and the RF signal received through the duplexer 116 is demodulated and output to the controller 100 through the interface 112. The codec 120 connected to the control unit 100, the microphone 47b and the speaker 47a connected to the codec 120 are voice input / output blocks used for phone calls and voice recording. The control unit 100 and the memory 110 basically correspond to blocks for processing and controlling telephone calls, data communication, and information terminal functions in a conventional composite wireless terminal.

The control unit 100 includes a micro-processor unit (MPU) 102 and a liquid crystal display controller (LCDC) 104. The LCDC 104 is a display controller, controlled by the MPU 102 and controls the display of the LCD 106.

The button part 27 collectively collectively names all button inputs such as function keys 40, 41, 42, 43, 44, 45, 46, etc., which are disposed on the side of the base 12 (not shown in the other drawings of this document). It includes, and provides the key data corresponding to the user's key press to the MPU (102). As described with reference to FIGS. 1 to 4, the keypad 45 has different functions according to each mode setting.

The hinge sensor unit 80 is composed of an X-slide hinge sensor 81a and a Y hinge sensor 82a. Each sensor detects the operation of each hinge, and transmits the information to the MPU. Check the status, and check whether the user is using the keyboard main body (13). If it turns out that the keyboard main body is in use, the screen 48 is rotated 90 degrees to realize a horizontal display.

The process of figuring out the state of the hinge and whether the screen is arranged horizontally or vertically and applying the same is the flow chart of FIG. 8.

Finally, keep in mind that the present invention is quite new because it is a new form factor. That is, a smartphone, a general mobile phone, a PDA, and the like, and in the future, a personal media player (PMP), a personal media center (PMC), etc., which are referred to as portable multimedia devices, fall into the scope of application of the present invention. Of course, when used as a PDA or smartphone, a touch panel is provided along with a general LCD screen.

By applying the present invention, the convenience of text input is drastically improved in E-mail transmission, SMS text service usage, and the like. In addition, the choice is wider to select the input method, and the horizontal display can be implemented as needed to facilitate the use of multimedia content.
