BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dual monitor device. The present invention relates to a dual monitor device having only one AD board and a power inverter of a monitor and distributing it to two displays to enable dual monitor image output and control.

In general, a dual monitor has two LCD screens, and two different LCD screens output different screens respectively to enable multitasking, or two LCD screens display the same screen to display the same screen with others. It can be used for counseling or entertainment.

Conventional dual monitors had a problem of using a splitter to output various images on each LCD screen.To improve this, two LCD controllers are switched by one signal controller by receiving two images through two ADCs. A dual monitor control device that outputs two LCDs has been developed.

However, since a large number of switching circuits and gates are required because two signals must be switched in one signal controller, there are disadvantages in signal attenuation or external noise due to image switching in two ADCs. I was worried about the image quality deterioration.

In order to improve this, in the image output control apparatus of Korean Patent Laid-Open Publication No. 10-2005-0118263, it is necessary to switch by configuring a switching unit which is responsible for switching switching such that the dual monitor outputs the same screen or a different screen to the analog-digital conversion stage. The signal line can be greatly reduced, so that switching circuits and gate circuits for processing RGB signals in the switching stage can be reduced, resulting in simplicity of circuits and cost reduction of circuit parts, and finally reducing the total volume of the dual monitors. In addition, the signal amplification unit that can amplify the RGB analog signal provided from an external PC in front of the analog-digital conversion unit is configured before the analog-digital conversion stage, thereby preventing signal attenuation and external noise that may occur during image switching. Dual monitor video output control cabinet It is disclosed.

 However, the image output control apparatus of the dual monitor disclosed in Korean Patent Laid-Open Publication No. 10-2005-0118263, which has two inputs using an ADC, must have an ADC which is unnecessary for processing an image output as a DP or HMDI digital signal. In addition, the display of the same screen on two monitors, the output of different screens on the two monitors, or switching between the two screens, such as the display of the dual monitor screen is limited to use for a variety of purposes.

As shown in the drawing, when the first input is received through the first input port 110 and is input to the display output selector 140 through the display control selector 130, the first display panel based on the output mode. The first input may be identically output to the second display panel 10 and the second display panel 20. In other words, it is an example of outputting the one-port input to the same panel with two panels. This allows the same screen to be seen from both sides facing each other.

Of course, although the first input is illustrated in FIG. 3, the second input may be input as a one-port input and output to the second panel on the same screen as the second input. This can be controlled by selecting which input port input is received in the input mode.

4 is an exemplary view of a one-port input two panel single extended screen of the dual monitor control apparatus according to the present invention.

As shown in FIG. 4, the input mode is a one-port input, and the output mode is an example of setting the two-panel single extended screen mode. The first input is input as a one-port input, and the first and second display panels 10 and 20 are extended to one screen and output as an extended screen. In this way, the two-panel display can be expanded to a single screen, which is a function not existing in the conventional dual monitor controller, and the full-screen size is enlarged to the two-panel.

For example, if the optimal horizontal resolution of one display panel is 1920 X 1080, if the resolution of the input signal is input at the optimal resolution 1920 X 1080 for a single panel output from a normal PC, the display output selector forcibly displays the screen. Only the horizontal size of the output will be increased. If the size is forcibly increased, the resolution is lowered and the clear screen cannot be seen. In order to solve this problem, in the present invention, when outputting to a one-port input two-panel single extended screen, the input resolution is input to a horizontal resolution of a two-panel single extended screen, that is, a horizontal resolution twice the optimal horizontal resolution of a single panel. To control.

In the present invention, the display control selector 130 is a PC that provides a single port input under the control of the mode controller 150 in the one-port input two-panel single extended screen mode. To provide. In other words, when the PC outputs the monitor, the monitor resolution information (size information) is received and input is provided at a resolution matching the resolution information. The present invention uses this, and the display control selector 130 may be implemented by updating the resolution information for each mode in correspondence to the input mode and the output mode and providing the same to the PC. The resolution information is varied by the input mode and the output mode set in the mode controller 150.

5 is a view illustrating a two-port input to panel individual screen output of the dual monitor control apparatus according to the present invention.

As shown in FIG. 5, both the first and second input ports 110 and 120 are driven to receive a two-port input. In this case, the resolution of each input is set to match the single panel resolution. The two-port input is output by the display output selector 140 to the individual screens corresponding to the first and second display panels 10 and 20, respectively. Of course, the first input and the second input may correspond to either the first or second display panel. That is, as shown in FIG. 5, the first input may be output to the first display panel and the second input may be output to the second display panel. The first input may be output to the first display panel by swapping the inputs and outputs, and the second display panel. It is also possible to output the first input to the screen.

As described above, in the input two-panel individual screen output mode, the two inputs may have a difference in luminance or color. In this case, the user selects a screen through the OSD key input unit 151, and adjusts the brightness or color of the selected screen by adjusting the brightness or color of the selected screen.

6 is an exemplary view of two-port input two-panel multi-split screen output of the dual monitor control apparatus according to the present invention.

As illustrated in FIG. 6, when the two-port input two-panel multi-split screen is set in the input mode and the output mode setting, the first and second inputs, which are two-port inputs, are received and the first and second displays 10 are input. 20 can be divided into two sections and output to the first, second, third and fourth divided screens on the two panels. In this case, the first and second inputs are assigned to the first and second split screens, and the first and second inputs are assigned to the third and fourth split screens, respectively, so that the two inputs can be viewed as split screens on the display panel of Hona. It is. The screen splitting technique divides the horizontal line address of each display panel by the display pull selector and displays the first and second inputs in correspondence with each other. The screen splitting technique can be applied in the same manner as the conventional screen splitting method. Matching may be performed in correspondence with each split screen. This allows the user to set each input corresponding to the split screen when setting the mode.

7 is an exemplary diagram of multiple input ports of the dual monitor controller of the present invention.

In the embodiments of the present disclosure, a configuration having two port inputs, that is, first and second input ports 110 and 120 is taken as an example, but is not limited thereto. As illustrated in FIG. 7, The dual monitor control apparatus 100 further includes an auxiliary input port 121 as a digital input port, and selects and controls the auxiliary input port when setting an input mode and an output mode.

When the auxiliary input port 121 is further provided as described above, the third input can be further received, and the scalability can be increased by selecting the auxiliary input port in the mode selection to set the output mode. Therefore, it is possible to divide the multi-split screen into three split screens per panel and to output the three-port input corresponding to each split screen.

On the other hand, although not described in the embodiment with reference to the drawings of the present invention, the mode control unit such as the input mode, output mode and color adjustment through the OSD key input unit, the mode is controlled by the PC control by communicating with the PC connected to the input port In addition, the set mode information may be stored in the mode control unit 150 to control the input mode and the output mode, that is, provide a mode setting menu, and display the mode information selected through the PC in the mode setting menu. ) Is set as mode information to control the input and output modes of the dual monitor controller.
