As shown in Figure 9, for there not being on the graphics card 11 situation of LVDS signal integrated, export to again on the screen of LCD display 12 after then first output signal of output also needs to convert to the LVDS signal from graphics card 11.Therefore, above-mentioned main frame also comprises the 2nd LVDS signal converter 19, be connected with display 12 with first gate 15 respectively, be used to receive first output signal of the next graphics card 11 of first gate, 13 transmission, and after converting first output signal to the LVDS signal, export to again on the screen of LCD 12, perhaps receive the external signal of coming by 13 transmission of first gate, and after converting external signal to the LVDS signal, export to again on the screen of LCD 12.
As shown in figure 10, in Fig. 9, first output signal of graphics card 11 exports on the screen of display 12 of this machine by first gate 15, the 2nd LVDS signal converter 19 successively, and second output signal of graphics card is through second gate 16, export transmitted in both directions port one 3 (as the VGA/DVI port) to, and situation about transferring out by transmitted in both directions port one 3.
As shown in figure 11, in Fig. 9, receive the external signal of coming successively by second gate, 16, the first gates, 15, the two LVDS signal converters 19, export the situation on the screen of display 12 of this machine to from transmitted in both directions port one 3.
In the above-described embodiments, display 12 can notebook computer LCD, graphics card 11 can be video card, transmitted in both directions port one 3 is VGA/DVI port or HDMI (HDMI), under the sight that adopts in the future the Displayport method to transmit, transmitted in both directions port one 3 also can be a standard Displayport port in the future, as shown in figure 12, when transmitted in both directions port one 3 is standard Displayport port, because the Displayport signal can directly drive LCD screen, so just without any need for change-over circuit goes to drive LCD display, then can not increase any conversion of signals cost for current implementation method.
As shown in figure 13, first gate 15 is hilted broadsword two-position switch circuit or alternative data selector, comprise a signal input end, the first data-signal input end, the second data-signal input end and a data-signal output terminal, wherein, the control signal that signal input end is imported, the data-signal that is used to select the data-signal that the first data-signal input end imported or the second data-signal input end to be imported, and export this data-signal by the data-signal output terminal.As the chip selection signal among the figure is to come from 0 or 1 control signal that hardware toggle switch 14 produces, and when chip selection signal was 0, the data-signal of selecting the first data-signal input end to be imported was exported by the data-signal output terminal; When chip selection signal was 1, the data-signal of selecting the second data-signal input end to be imported was exported by the data-signal output terminal; Certainly, when chip selection signal was 0, the data-signal that also can select the second data-signal input end to be imported was exported by the data-signal output terminal; When chip selection signal was 1, the data-signal of selecting the first data-signal input end to be imported was exported also and can be realized by the data-signal output terminal.
As shown in figure 14, second gate 16 is the gate of hilted broadsword two-position switch or the output of two passages, comprise a signal input end, a data-signal input end, first transmission channel and second transmission channel, wherein, the control signal that signal input end is imported is used to the data-signal of selecting the data-signal input end to be imported, and transfer out by second transmission channel, the external signal of perhaps selecting the transmission of second transmission channel is exported this external signal by first transmission channel; As the chip selection signal among the figure is to come from 0 or 1 control signal that hardware toggle switch 17 produces equally, when chip selection signal is 0, select the data-signal (data-signal that the data-signal input end is imported) and second transmission channel of graphics card 11 or 17 outputs of the 3rd gate to export, and cut off first transmission channel; When chip selection signal is 1, select first transmission channel and second transmission channel to receive external signal, the signal that cuts off graphics card 11 or 17 outputs of the 3rd gate, second transmission channel in the present embodiment is the transmitted in both directions passage, both can send data-signal, also can receive data-signal from the outside to the outside; Equally, when chip selection signal is 0, select first transmission channel and second transmission channel to receive external signal, cut off the signal of graphics card 11 or 17 outputs of the 3rd gate; When chip selection signal is 1, select the data-signal (data-signal that the data-signal input end is imported) and second transmission channel of graphics card or 17 outputs of the 3rd gate to export, and cut off first transmission channel, also can realize.

Again in conjunction with Fig. 3-Figure 15, when toggle switch 17 pushes (perhaps closed condition) on one side, the signal that system receives just is 0,
The 3rd gate 17, the input chip selection signal is 0, opens the 3rd gate 17, can normally export from second output signal of graphics card 11 and be given to second gate 16.
Output to LCD with regard to having realized from the signal of graphics card 11 like this, and simultaneously the signal of graphics card 11 is exported to outside the use by the VGA/DVI mouth.
When toggle switch 17 pushes another side (perhaps opening attitude), the signal that system receives just is 1,
The 3rd gate 17, the input chip selection signal is 1, closes the 3rd gate 17, no signal is exported to second gate 16.
Output to LCD with regard to realizing from the signal of outside like this.
The foregoing description increases the hardware toggle switch by the transmitted in both directions port at computing machine (as notebook computer), be input to the LCD display curtain by the LVDS signal converter after with external signal input conversion, thus the switching in simple realization notebook computer liquid crystal curtain selectable use local signal source or external input signal source.Thereby thereby realize utilizing the screen of notebook circuit to carry out the expansion of corresponding function as input video source.
Be the concrete application scenario of aforementioned calculation machine below:
In a mini-session, many the notebook computers with said structure are connected into a server computer, transmitted in both directions port by every notebook computer, reception is from the vision signal of server computer, can see same vision signal on the screen of every notebook computer, employing this programme not only can slowly be eliminated paper and pen but also can prevent that material is copied from meeting room.
In addition, in a big exhibition, both many notebook computers can be connected into same computing machine, realize display synchronization, and also can provide the video line of video flowing also can prevent to be copied specially for user's use.
The advantage that the above embodiment of the present invention produced is: by introduce two-way input/output port control at the display ports such as VGA/DVI of computing machine, solving notebook computer can only have and show output and do not have the problem that shows input information, thus can realize between notebook or and other main frame between the sharing, show synchronously of signal source; Simplifying mini-session hardware needs, and the meeting people only need carry the computer that has the input and output of two-way video signal, just can be connected into conference host by common video line connecting line, thereby need not additionally drive, additional networks realization conference content shows synchronously; The output of host desktop information just can be realized in also extensible desktop computer utilization space under the situation that host desktop and notebook computer are only arranged.
