Description

Mobile phone with multi-screen function {Mobile phone with multi-screen}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile phone. In particular, as the liquid crystal of the mobile phone is enlarged, the multi-screen is divided into multi-screens so as to differentiate and express the contents displayed on each screen. It relates to a mobile phone with a screen function.

With the development of mobile phones, people who play games or play videos using color mobile phones can be bored.

Mobile phone terminals, which have only become smaller, have grown in size, with large and color LCDs, which allow users to enjoy video on demand (VOD) and video communications with the recent launch of high-speed mobile communication services such as cdma 1x. Therefore, in order to increase the size of the LCD while reducing the size of the mobile phone itself, most mobile phone companies are introducing folding terminals, which are folding mobile phones.

Recently, however, with the introduction of the IMT2000 service, the mobile phone handset has grown again, with the emphasis on the 'looking' function rather than the 'listening' function of the mobile phone. As the demand for enjoying a variety of color content on a larger screen increases, terminals, which were once reduced to less than 80 mm (length), are growing to 100 mm.

As the liquid crystal of the mobile phone increases in size, it would be good if the liquid crystal of the mobile phone could be divided into two or more screens and displayed in a multi-screen manner.

Accordingly, the present invention has been made to meet the above requirements, and as the liquid crystal of the mobile phone is increased in size, the liquid crystal of the mobile phone can be divided into two or more screens to express various contents in one liquid crystal. It is an object of the present invention to provide a mobile phone with a multi-screen function.

The present invention for achieving the above object, a memory for storing the multimedia image data and the basic screen data received in response to the service request of the mobile terminal; An image output processor configured to read multimedia image data and basic screen data from the memory and configure a multi-screen after outputting a multi-screen configuration control signal; A display unit which displays a multi-screen output from the image output processor; And a control unit for outputting a multi-screen configuration control signal to the image output processing unit.

Now, with reference to the drawings of Figure 1 will be described in detail a preferred embodiment of the present invention.

1 is a schematic block diagram of a mobile terminal having a multi-screen function according to an embodiment of the present invention.

Referring to FIG. 1, the terminal controller 4 controls the overall operation of the mobile terminal such as call and general functions (phone number management, schedule, voice dialing, ring mode selection, display control, etc.) of the mobile terminal.

The memory 130 stores various programs, phone number data, schedule data, and the like for performing operations of the wireless terminal.

The RF unit 120 performs up-converting and down-converting, filtering, and amplifying, and receives and transmits a radio signal.

The key input unit 140 has a number and a plurality of function keys.

The display unit 150 is operated by the display unit driver 151 and may be configured as a TFT color LCD (Liquid Crystal Display) and outputs character information, menu information, still images, moving images, and the like. The driver 151 drives the display unit 150.

A modulator 161 (CODEC) demodulates and outputs the received voice and modulates and outputs the voice input through the microphone. The modulator 161 may be implemented as a digital signal processor (DSP) chip.

The switching unit 162 switches the voice output from the modulator 161 and the voice input from the user to form a micro path with the modulator 161, the ear microphone 163, or the speaker provided in the mobile terminal.

The image processor 6 buffers the text information, the menu information, the still image, and the moving image information received from the terminal controller 4 and the multimedia service processor 2, and converts the D / A data to the driver 151 or buffers the data. To be transmitted to the drive unit 151 to output.

The multimedia service processor 2 performs an operation for connecting to a corresponding server and requesting data according to a multimedia service request of a user, and buffers and outputs received voice and image data in real time, and when receiving the image data. It outputs through the image processing unit 6 and outputs through the demodulator 161 upon receiving voice data.

FIG. 2 is a block diagram of the image processing unit of FIG. 1, which includes a first memory 26 for temporarily storing image data transmitted from the multimedia processing unit 2, and a basic screen (display unit of a conventional mobile phone) from the terminal control unit 4; Basically displayed screen) The second memory 32 which receives and stores data and the output of the first memory 26 and the output of the second memory 32 are synthesized under the control of the terminal controller 4. At the top of the screen, a basic screen according to the output data of the second memory 32 is provided, and at the bottom of the screen, an image processor 50 for providing an advertisement screen, a TV playback screen, etc. according to the output of the first memory 26 is provided. Equipped.

Now, referring to Figures 1 and 2 will be described in detail the operation of the mobile phone equipped with a multi-screen function according to an embodiment of the present invention.

The control unit 4 reads data related to the basic screen from the memory 130 and transmits the data related to the basic screen to the second memory 32 and according to the basic screen data stored in the second memory 32 in the image output processing unit 50. The display device 7 is driven to display the basic screen on the display unit 150.

In addition, the controller 4 provides a multi-screen menu to the user so that the user divides the screen when the user wants to split the screen so that one of the divided screens is provided with basic information related to the mobile phone, and the other. The advertisement or TV playback screen is provided.

Here, the multi-screen menu includes an advertisement providing menu and a TV play menu as sub menus to provide information on the divided screens according to the sub menu selected by the user.

Meanwhile, when the user selects a multi-screen menu and selects an advertisement providing menu or a TV playback menu, the controller 4 drives the multimedia service processor 2 to display image data related to an advertisement or a TV playback video screen in a first memory. Control to output to (26).

The controller 4 controls the image output processor 50 to divide the screen so that one of the divided screens displays image data stored in the first memory, and the other of the divided screens displays the second memory. Controls to display basic screen data saved in.

The image output processing unit 50 divides the screen when the multi-screen configuration control signal is input from the control unit 4, and configures one of the divided screens so that the image data stored in the first memory 26 is represented, and the other screen. Is configured to express the basic screen data stored in the second memory 32, and outputs the full screen consisting of two divided screens to the graphic display device 7.

Then, the graphic display apparatus 7 receives the screen data divided by the image output processing unit 50 and displays it on the display unit 150.

3 shows an example of a screen on which two screens 210 and 220 are displayed.

Here, the main screen 220 is displayed on one of the screens, and the advertisement screen or the TV screen 210 is configured on the other, but the busy / database service screen is displayed on one of the screens and the terminal menu on the other. It can also be implemented to make the screen appear.

Although the present invention has been described in detail with reference to preferred embodiments, the scope of the present invention is not limited to the specific embodiments, and should be interpreted by the appended claims.

According to the present invention as described above, there is an effect to display a unique function for each screen by dividing one liquid crystal into several.
