BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal portable terminal, and more particularly, to a variety of terminal devices that can be used without being restricted by a place.

The personal portable terminal widely used herein is a portable electric and electronic device such as a PDA (Personal Digital Assistant), a smart phone, a handheld PC, a mobile phone, an MP3 player, and the like, and code division multiplexing. Access) module, Bluetooth module, infrared communication module (IrDA), can be provided with a predetermined communication module, such as wired and wireless LAN card, and is equipped with a predetermined microprocessor that performs a multimedia playback function collectively referred to a terminal having a predetermined computing power It is a concept.

The personal mobile terminal uses the principle that when a user in a mobile communication service area makes a phone call to the personal mobile terminal, the wireless base station is wirelessly connected to the first base station. That is, there are a large number of wireless zones in the mobile communication service area, and there are wireless base stations for each wireless zone, so that the base station and the mobile phone are connected wirelessly. In addition, when connecting with a general subscriber, the wireless network is connected to a base station, and then a call is made through a control station or an exchange station through a wire.

In the early stages of development of the conventional personal portable terminal, there was a disadvantage of being affected by the topography such as the basement of a building or a mountainous area. However, since 2000, the manufacturing technology developed very rapidly, and these disadvantages were almost overcome. In addition, in recent years, not only voice calls but also texts can be left through the LCD screen, voice features have been extracted and the next time, the voice recognition mobile phone is found to find the closest feature of the voice. In addition, personal handheld devices that fully implement alarm functions, traffic and securities providing functions, and even videos have appeared.

However, conventional personal portable terminals usually have a screen size of about 320 * 240. Therefore, in recent years, the size of the display is inconveniently small to watch multimedia such as the Internet, TV viewing and movies. Therefore, in order to solve such a problem, Korean Patent Publication No. 10-2004-0069979, "Portable Multi Display Device", is disclosed.

1 and 2 are views showing the exterior of a conventional multi display device.

As shown in Fig. 1, the portable multi-display device of the present invention is provided with two panel housings 20 and 40 on which respective displays 2 and 4 are mounted. When the display device is unfolded, one side of the display 2 or 4 is adjacent to each other. That is, one side of the display 2 or 4 is in contact with or close to each other to form a single screen, wherein the joints 8 'of the display are adjacent to each other.

The two panel housings 20 and 40 are connected by connecting means 6 which can be folded and unfolded. In this embodiment, a hinge is used as the connecting means 6. In addition, the two panel housings 20 and 40 are each connected to the circuit, and the circuit connecting means is omitted in the drawing.

2 is a view showing a form in which a display is mounted on one panel housing.

The panel housings 20 and 40 are provided with openings 8 that serve to allow at least one side of the display 2 and 4 to be adjacent to each other. The opening 8 does not necessarily have to be drilled, and the opening 8 is formed to be much thinner than the side surfaces 20a of the panel housings 20 and 40, so that at least one of the displays can be opened through the opening 80. You just need to be close to the edge

However, the conventional multi-display device is a form of opening and closing in a folder form, and when applied to a personal portable terminal, its size increases and thus the portability of carrying it anywhere can be reduced. In addition, since it is always used in a multi-display mode, power consumption other than the required power is generated, and if the conventional technology is applied to a mobile phone, its shape is inconvenient to make a phone call.

Therefore, the conventional personal portable terminal has been studied in the direction of simply mounting a large display device or a high resolution display device. However, this method is also difficult to overcome the fundamental problems of the resolution limitation of the eye and the limitation of the display size.

Accordingly, an object of the present invention for solving the above problems of the present invention is to provide a personal portable terminal including a dual display module capable of providing a large screen using a dual display.

The first display module is mounted on the terminal body and outputs an image signal. The second display module is mounted to be slidable relative to the first display module. In this case, one of the first display module and the second display module may slide or all may slide. The controller is electrically connected to the first and second display modules and controls the image signals transmitted to the first and second display modules according to mutual positions of the first and second display modules. Therefore, the first display module and the second display module may slide to provide a large screen to the user.

 Conventional personal portable terminals are simply equipped with a large display device to provide a large screen, or a display device with a high resolution to provide a high quality display. However, in the conventional personal portable terminal, the size of the personal portable terminal is increased due to the large display, so the portability is very low, and it is difficult to overcome the fundamental problems of the limitation of the resolution of the eyes and the limitation of the display size. The personal portable terminal according to the present invention is equipped with first and second display modules, and one or both of the first and second display modules are arranged in parallel positions or parallel to each other in a parallel position overlapping each other. Sliding movement can make a large screen. Therefore, in general, the first and second display modules are fixed in a serial position to increase portability, and when necessary, the first and second display modules are moved to a parallel position or a parallel position to provide a large screen. It has the same effect as watching TV, not the display of a personal digital assistant.

In addition, according to another preferred embodiment of the present invention for achieving the above object of the present invention, a personal portable terminal includes a terminal body, a first display module, a second display module, a controller and a driver.

The main body of the terminal is a body of a personal portable terminal, and may be manufactured in various forms such as a folder type, a flip type, a swing type, a slide type, and the like according to the opening and closing type of the portable terminal. The first display module is mounted on the terminal body to allow sliding movement and output an image signal. The second display module is mounted to be slidable relative to the first display module. The controller is electrically connected to the first and second display modules and controls the image signals transmitted to the first and second display modules according to mutual positions of the first and second display modules. The driver is formed on the sides of the first and second display modules, and is electrically connected to the controller to move the first and second display modules by the same distance by the driving signal of the controller. Therefore, the first display module and the second display module can be automatically moved by the driving unit to provide a large screen to the user.

The terminal body 210 is a body of a personal portable terminal, in which a first display module 220 and a second display module 230 are mounted on a front surface thereof, and a key input unit 212 for inputting a character is formed at a lower portion thereof. In addition, the second magnetic body 280 may be mounted on the terminal body 210 at the position of the terminal body 210 corresponding to the first magnetic body 270 after the sliding movement. In addition, the sensor 282 is mounted at a position adjacent to the second magnetic body 280 to detect that the second magnetic body 280 and the first magnetic body 270 are in contact with each other. However, in another embodiment of the present invention, a module such as a mobile phone, an mp3 player, and a digital camera may be further mounted to the terminal body according to the designer's intention. In addition, the terminal body 110 may be manufactured in various forms such as a folder type, a flip type, a swing type, a slide type, and the like according to the opening and closing type.

The first display module 220 is formed on the front surface of the terminal body 210, and both ends of the first display pin 220 are formed on the guide frame 260 connecting the side of the terminal body 210 and the first display module 220. 262a).

Referring to FIG. 10, the cable unit 250 includes a first cable 252 and a second cable 254. The first cable 252 is embedded in the lower portion of the terminal body 210 so that one end thereof is electrically connected to the controller 240 and the other end thereof is connected to the first display module 220. Therefore, when the first display module 220 moves, the first cable 252 moves together. The second cable 254 is embedded in the lower portion of the terminal body 210 so that one end thereof is electrically connected to the controller 240 and the other end thereof is connected to the second display module 230. Therefore, when the second display module 230 slides, the second cable 254 also moves together. However, in another embodiment of the present invention, the positions of the first cable and the second cable may be changed according to the designer's intention.

Accordingly, in the personal portable terminal including the dual display module according to the present invention, the height is identical between the first display module and the second display module, and it is inconvenient for a user to divide and watch one image signal in each display module.
