In this case, the monitor, which is a display device, reproduces a signal transmitted from a graphics card under a control of a CPU mounted on a main board, and outputs a predetermined image on a screen for the user to view. Such a computer has a configuration in which a main body on which a main board is mounted, a graphic card of the main body, and a display device are connected by cables.

Recently, various types of integrated computers in which a main body and a display device are integrally released have been released. Since the integrated computer does not require a cable for connecting the main body and the display device and a cable for supplying power to each other, the integrated computer has advantages in terms of space utilization and design.

1 is a diagram schematically illustrating an example of an all-in-one computer generally released recently.

As shown, the unitary computer 10 has a design similar to a general display device. However, the integrated computer 10 is characterized in that the display device 30 is installed on the front surface, and the main body is integrally formed with the display device 30 on the back surface.

FIG. 2 is a diagram illustrating a connection structure between a main body and a display device in the integrated computer 10 of FIG. 1.

As shown, the main board 20 mounted on the main body and the display device 30 are connected through a cable 1 for image data transmission.

The motherboard 20 is equipped with a CPU (Central Process Unit) 22 and a graphics card 24. The CPU 22 controls the overall operation of the computer and controls the operation of the graphics card 24 for outputting image data. The graphics card 24 is equipped with a digital to analog converter (DAC) 26 for converting the format of the image data from digital to analog so that the image data is transmitted through the cable 1.

In response, the display device 30 includes an analog to digital converter (ADC) 36 for converting analog image data transmitted through the cable 1 into a digital format. The image data in the converted digital format is displayed to be viewed by the user through the panel 32.

The computer 10 simultaneously displays page windows having various information on one screen of the display device 30 according to a user's manipulation. For example, one screen of the display device 30 displays execution page windows of programs executed by a user and web pages provided through an Internet connection.

As described above, when a plurality of tasks are simultaneously performed on the computer 10, the conventional display apparatus 30 configured as one screen is limited in space to simultaneously display the execution screens of each program on one screen. There is a disadvantage that the inconvenience of working. In order to solve the limitations of the work space, a technology for securing a work space by connecting two display devices to one computer main body may be proposed.

The graphics card 54 is equipped with DACs 56 and 58 for converting the format of the image data from digital to analog so that the image data is transmitted via the cables 3 and 5.

Correspondingly, the display device 60 includes ADCs 64 and 68, respectively, for converting analog image data transmitted through the cables 3 and 5 connected to the DACs 56 and 58, respectively, into a digital format. The image data in the converted digital format is displayed for the user to view through the main panel 62 and the auxiliary panel 66 connected to the ADCs 64 and 68, respectively.

The integrated computer 40 displays work status information through program execution of a computer through two screens, thereby securing a wider work space.

However, even in the dual display device as described above, there are limitations in displaying a plurality of programs simultaneously on two screens. Accordingly, there is a need for a display apparatus capable of securing a wider work space for displaying a plurality of program processing result data.

However, there are disadvantages in manufacturing a product due to the following problems with existing integrated computers. That is, the existing integrated computer further includes a converter or a card having a converter for converting the format of the image data between the motherboard and the display device.

In addition, the display device must be equipped with an analog to digital converting (AD) board having an ADC converting function to display image data received from the main board.

In addition, since a graphics card is mounted on the motherboard for outputting image data, the overall size of the product is increased. In addition, in order to produce an integrated computer capable of outputting three or more different image data, an expensive graphic card having a special function is required separately.

An object of the present invention for solving the above problems is to provide a computer body capable of outputting two or more different images and a computer in which multiple panels connected thereto are integrally formed.

Another object of the present invention is to provide a computer main body capable of outputting two or more different images without a separate graphics card and a multiple display device formed integrally therewith.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

5 is a diagram illustrating an integrated computer manufactured by casing a triple display device and a main body according to a preferred embodiment of the present invention.

As shown, the integrated computer 100 according to the exemplary embodiment of the present invention includes a triple display apparatus 400 including a main panel 420, a first auxiliary panel 440, and a second auxiliary panel 460 on a front surface thereof. Is disposed, and a main body of a computer for outputting image data to the triple display device 400 is disposed on the back side.

In the present exemplary embodiment, the main panel 420, the first auxiliary panel 440, and the second auxiliary panel 460 have a single body, and the first auxiliary panel 440 and the second auxiliary panel 460 are formed of a main body.

In the present exemplary embodiment, the main panel 420, the first auxiliary panel 440, and the second auxiliary panel 460 are connected to the main body of the computer through low voltage differential signaling (LVDS) cables, respectively. Has

As such, by configuring three panels capable of displaying the image data output from the computer main body, there is an advantage in that a larger number of working spaces can be secured compared to the existing display device composed of one panel or two panels. .

Hereinafter, the structure which integrates the triple display apparatus 600 which consists of three panels, and a main body in one casing is demonstrated.

6 is a diagram illustrating an example of connecting a triple display apparatus and a computer main body to display image data according to an exemplary embodiment of the present invention.

As illustrated, the triple display apparatus 400 includes a main panel 420, a first auxiliary panel 440, and a second auxiliary panel 460.

Here, the main panel 420 includes an LVDS receiver 410 for receiving image data output from the main board 200, and in this case, the LVDS receiver 410 receives the input image data in a digital format. Allows you to display image data directly on the panel.

The second auxiliary main panel 460 includes an LVDS receiver 450 for receiving image data output from the main board 200.

Here, low voltage differential signaling (LVDS) is a universal interface standard for high-speed data transmission. LVDS provides higher bit rates, lower power and improved noise control. LVDS is widely used in point-to-point applications for telecom, data communications, display devices, etc., with proven speed, low power, noise control, and cost advantages. In addition, LVDS uses a high-speed analog line technique to enable multi-gigabit data transmission over copper interconnects. Of course, standard communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 1394, fiber channel, and Gigabit Ethernet are used for high-speed data transfer between systems. However, since the cost burden of hardware and software for the standard system-to-system communication protocol is too large for data transmission between systems, a simple and inexpensive LVDS link has been widely used. In addition, LVDS uses a low voltage, which reduces the occurrence of Electro Magnetic Interference (EMI), which reduces the impact on adjacent circuits, and is more advantageous for electromagnetic interference tests, which are becoming more stringent in recent years. In addition, the use of low voltage has the advantage that the power consumption is reduced. In this embodiment, the LVDS technology having such an advantage is applied as a transmission interface of image data between the main body and the display device.

As described above, the digital data may be directly received from the main board 200 of the main body via the LVDS receivers 410, 430, and 450 provided in the triple display apparatus 400 including three panels, and displayed on each panel. By configuring to do so, there is no need to additionally have an AD board for ADC conversion in each of the panels 420, 440, 460. Accordingly, there is an advantage that the overall size of the integrated computer 100 can be miniaturized.

Meanwhile, the main board 200 of the computer illustrated in FIG. 6 includes a CPU 210, a communication unit 220, an input interface 230, an audio output unit 240, a storage unit 250, a graphic processing unit 260, 270, 280, And low voltage differential signaling (LVDS) output units 265, 275, and 285.

The CPU 210 controls overall operations of the computer 100, and controls operations of the graphic processing units 260, 270, and 280 for outputting image data to the triple display device 400.

The communication unit 220 accesses a website through an internet network and receives data provided from the accessed website. In this case, the Internet network is commonly referred to as a wired or wireless communication network. In addition, the Internet network in the present invention includes not only the Internet but also an intranet, which is a private network, and an extranet.

In the present invention, the advertisement content providing server is accessed through the Internet to receive data provided from the advertisement content providing server. Here, the advertisement content providing server stores and manages the advertisement data received from the advertisement requesting companies that want to advertise through the triple display apparatus 100 of the present invention as a database, and stores the web data from a computer connected to the triple display apparatus 400. When the site access signal is received, the advertisement data is stored to the computer.

The input interface 230 receives a command input from the user unit and provides the command to the CPU 210. In the present embodiment, the input interface 230 receives a selection command of a panel for displaying image data input from a user and provides it to the CPU 210. In general, the input interface 230 of the present embodiment may be a keyboard or a mouse connected to the main board 200 of the computer.

The audio output unit 240 outputs audio data generated from a corresponding program executed according to a command of the CPU 210 through a speaker.

The storage unit 250 stores an access program for accessing a specific website set through the Internet while power is supplied to the main board 200 and the system is turned on. Here, in the access program, the storage unit 250 applies a connection command of a specific website to the CPU 210 while the power is applied, so that the CPU 210 accesses a specific website through the communication unit 220. It is an executable program.

Here, the specific web site is an advertisement contents providing server, and the advertisement contents providing server manages the advertisement contents requested by the companies and performs the function of providing the advertisement contents through the Internet network.

The graphic processing units 260, 270, and 280 are connected to the CPU 210, respectively. The graphic processor 260, 270, 280 converts the image data into a format that can be displayed on the panels 420, 440, 460 of the triple display apparatus 400 under the control of the connected CPU 210.

The LVDS output units 265, 275, and 285 are connected to the graphic processing units 260, 270, and 280, respectively. The LVDS output units 265, 275, and 285 convert the received image data into low voltage differential signals and output the high speed image data received from the graphic processing units 260, 270, and 280, respectively.

As described above, according to an exemplary embodiment of the present invention, the main board 200 does not need a separate graphic card for outputting the image data to the triple display apparatus 400, and directly outputs the image data in a displayable digital format. Have

The LVDS output units 265, 275, and 285 of the main board 200 are directly connected to the LVDS receivers 410, 430, and 450 of the triple display apparatus 400 through the LVDS cables 310, 330, and 350, respectively. Accordingly, as image data is directly transmitted from the main board 200 to the triple display device 400 in a digital format, it is not necessary to provide a separate AD board on each panel 420, 440, 460 of the triple display device 400. .

Due to this feature, the image data in the digital format output from the main board 200 is directly received by the main panel 420 and the first and second auxiliary panels 440 and 460 through the LVDS cables 310, 330, and 350 so that the panel does not have signal conversion. By being displayed on, the display speed of the image data is improved and the original image quality of the display image can be guaranteed.

Through such a system configuration, the CPU 210 controls the graphic processor 270 or 280 to display the image data provided from the advertisement content providing server on the first auxiliary panel 440 or the second auxiliary panel 460.

When the image data displayed on the first sub-panel 440 is selected through the input interface 230, the CPU 210 receives a web page linked to the selected image data through the communication unit 220 and receives the main panel ( The graphic processor 260 or 280 is controlled to output to the 420 or the second auxiliary panel 460.

That is, the main panel 420 displays the main processing contents of the program executed in the computer 100 connected to the triple display apparatus 100. The first auxiliary main panel 440 and the second auxiliary main panel 460 are displayed in linkage with a computer's usage environment, work data, and link information for connecting a web page according to a user's request.

As another example of the present invention, the first auxiliary main panel 440 may be set to display only data (for example, advertisement contents and private intranet information) provided from an external specific Internet website. That is, the first auxiliary main panel 440 is fixedly set for display of website-provided data that cannot be changed by the user, and the second auxiliary main panel 460 is configured to change any data that can be changed at the request of the user. Can be set for display purposes. Conversely, the first auxiliary main panel 440 may be set for a changeable display of arbitrary data, and the second auxiliary main panel 460 may be set for a fixed display of specific website-provided data.

As such, the present invention provides multiple display output software for additionally mounting a graphics card on the motherboard 200 of the computer or outputting different image data on each panel to connect the motherboard 200 and the display device 400. There is no need to configure it separately. In addition, it is possible to display image data on the panel without adding an expensive triple graphics card which is connected to the main, first auxiliary, and second auxiliary panels 420, 440, 460 in one graphic card, and configured to output different image data. By manufacturing the main board 200 to which the graphics processing unit 260, 270, and 280 that can be converted into a format is attached, it has an advantage of occupying a small installation space of a computer compared to the existing one and can provide aesthetic appearance.
