Referring to FIG. 2, the present invention attaches a large LCD (minimum 3 inches) 101 of a touch screen type to the terminal body 100, and a plurality of thin film speakers 102 and 103 thereon. By attaching), the front of the terminal is not equipped with other components (buttons, speakers) other than the LCD can increase the space utilization.

The thin film speakers 102 and 103 are made of a transparent material of at least 4 * 4 * 0.5 (mm), and can make a sound quality of 100dB.

On the side of the terminal body 100, only a minimum button for quick operation during a call, such as a power button and a volume up / down button, is disposed, and a navigation button and a number (letter) button are processed in software, so that the touch screen Input through the LCD 101 of the scheme.

In addition, the terminal body 100 should be added to the earphone jack in addition to the side button, in the present invention, by allowing the input / output of a sound signal in a Bluetooth manner, to save the space occupied by the earphone jack to minimize the thickness do.

Although the thin film speakers 102 and 103 attached on the touch screen LCD 101 are thin in thickness, the speaker may be damaged when pressure is applied directly onto the thin film speaker through a stylus fan for software button or menu selection. It can also reduce the sensitivity of the touch screen.

Therefore, when placing the thin film speaker, the position should be carefully selected, and menus and software buttons output on the LCD screen should be output so that the thin film speaker is not overlapped at the position where the thin film speaker is arranged.

In the exemplary embodiment of the present invention, the upper and lower scroll bars and the software buttons are mainly disposed on the upper and lower sides of the LCD to avoid the bottom of the screen and the center of the screen, and as shown in FIG. If it is small enough, it can be placed on the upper left / right side of the LCD screen and display the speaker image at that position, thereby excluding the stylus fan input.

On the other hand, if the thin film speaker is applied to the front of the terminal as described above, it may be considered that the audio is output to the front to ensure a secret call, but can be sufficiently solved by allowing the volume of the thin film speaker to be finely adjusted. do.

If the phone number and text message are input, the on-screen keyboard can be displayed for input, and the sub menu is sequentially selected by calling a menu for setting or controlling the function of the terminal. It also comes with a graffiti command to replace existing shortcuts and hotkeys.

The graffiti command function corresponds to a character (or a symbol, etc.) designated by a user and a function to be performed when the character is input, so that the character can be immediately executed by inputting the character if necessary without selecting a menu step by step.

Figure 4 is a block diagram showing the configuration of a mobile communication terminal having a multi-function display according to the present invention, the LCD 201 of the touch screen method for outputting and inputting information as shown therein, and the audio signal attached to the LCD A thin film speaker 202 for outputting a volume, a volume adjusting unit 203 for adjusting a volume of the thin film speaker, a graffiti command determining unit 204 for determining whether a character input through the LCD is a graffiti command, and The Bluetooth transmitter / receiver 205 for outputting sound output from the thin film speaker to the Bluetooth headset or receiving a user's voice through the microphone of the headset, processing of the command inputted through the graffiti command determination unit, and each component It comprises a control unit 206 to control the terminal to operate smoothly.

Here, the thin film speaker 202 is made of a very thin (about 0.5mm) made of a transparent material, it is possible to finely adjust the volume, therefore, when the volume up / down button attached to the side of the terminal main body, the control unit By determining this at 206, the volume adjusting unit 203 is controlled to adjust the thin film speaker 202 from the minimum volume (only possible to make a call) to the maximum volume (MP3, output to an external speaker when playing a video). .

In addition, when a Bluetooth switch (not shown) attached to the side of the terminal main body is input, the controller 206 cuts off the sound output from the thin film speaker, and passes through the Bluetooth transmitter / receiver to an external Bluetooth headset (not shown). Output sound.

Of course, all the buttons including the Bluetooth switch (button) can be implemented in software. For example, if the Bluetooth switch is registered as a graffiti command 'B', the 'B' command can be executed without having a Bluetooth location externally. By inputting, the direction of sound output can be switched immediately, and when the 'C' is registered as a graffiti command for driving the camera, the camera can be immediately driven.

That is, the graffiti command determiner 204 is driven in an interrupt manner so as to process other tasks performed by the controller in a manner of interruption. When the graffiti command is input even while performing other tasks, the controller terminates the currently executed task ( Or hold), and then process the currently entered graffiti command to perform the same function as an existing hotkey.

Hereinafter, the operation and operation of the terminal configured as described above will be described with reference to the flowchart of FIG. 6.

That is, since the terminal of the present invention uses the touch screen as a means for inputting commands except for the power on / off button, it is necessary to check whether there is a graffiti command or a software button input through the touch screen and perform a corresponding command. It is.

Therefore, when there is an input through the touch screen, it is determined whether the input is a graffiti command or a software button input.

In the case of a software button input, an operation corresponding to the corresponding button is performed. In the case of a graffiti command, an operation currently performed in the terminal is terminated (or suspended), and then a control operation corresponding to the corresponding command is immediately performed.

For example, the graffiti command may be variously played, such as playing an MP3 player or shooting a camera, and perform a corresponding operation according to the command.

In particular, when the sound needs to be output, such as during MP3 play or video playback, the sound is output through the thin film speaker, and when there is a sound output switch (bluetooth) switch (command) input during sound output, the sound output direction is directed to the thin film speaker. Switch to output to an external Bluetooth headset.

As described above, all the functions applied to the present invention can provide a wide screen to the user by making the thickness of the terminal thin and making the most of the space within the size of the existing general terminal to replace the LCD screen. It has the effect of making it possible.
