Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
Consult Fig. 2; Preferred embodiment for display device of the present invention; This display device 100 is one to have and can directly surf the Net and the display of multi-media player function; It can couple the row communication of going forward side by side with the external main frame 200 just like PC or notebook computer; In the present embodiment, display device 100 comprises a video signal input interface 1, one first transmission interface 2, at least one second transmission interface 3 (present embodiment is an example with two), a hub (HUB) 4, all die change pieces 5, a processing module 6 and a control module 7.
Video signal input interface 1 provides with a video signal line 210 of external main frame 200 and is electrically connected; It can be Video Graphics Array (Video Graphics Array; VGA), digital video interface (Digital Video Interface; DVI), HDMI (High Definition Multimedia Interface, HDMI) etc., in order to receive the signal of video signal that sent by external main frame 200.
First transmission interface 2 is electrically connected in order to provide with an information transmission line 220 of external main frame 200, make display device 100 can with external main frame 200 mutual data transmission and signals; Each second transmission interface 3 is electrically connected in order to provide with a signal transmssion line 310 of a peripheral unit 300 respectively; Make display device 100 can cooperate the control of peripheral unit 300 and carry out corresponding action; In the present embodiment, two peripheral units 300 are respectively a mouse (Mouse) and a keyboard (Keyboard), and first transmission interface 2 and second transmission interface 3 are all USB (Universal Serial Bus; USB) interface, but neitherly exceed with present embodiment.
Hub 4 is coupled to said second transmission interface 3, is provided with in order to provide a plurality of second transmission interfaces 3 to connect, make said peripheral unit 300 can with display device 100 interactions.Handover module 5 is one 1 pair 2 de-multiplexers (DEMUX); Its input end is coupled to hub 4; Two output terminals then are respectively coupled to first transmission interface 2 and processing module 6, and in order to the signal transmission path of switching peripheral unit 300, but handover module 5 also not only exceeds with de-multiplexer.Processing module 6 is coupled to handover module 5, in order to handling the signal that peripheral unit 300 is transmitted, and shows in a display module (figure does not show).Control module 7 is coupled to handover module 5 and video signal input interface 1, switches the signal transmission path of peripheral unit 300 in order to control handover module 5.What specify is; In another embodiment, display device 100 also can only be provided with one second transmission interface 3 and be electrically connected with single peripheral unit 300, under this design; Display device 100 can not need hub 4, if with second transmission interface 3 directly and handover module 5 couple.
Then, below will cooperate Fig. 3 to explain that the display device 100 of present embodiment is the signal transmission path that how to switch peripheral unit 300,, reduce its standby time, increase the convenience on using to make full use of peripheral unit 300.
Step S10; Whether control module 7 detecting video signal input interfaces 1 receive the signal of video signal that is sent by external main frame 200, if represent that then video signal input interface 1 is electrically connected with the video signal line 210 of external main frame 200; The user can show the picture of external main frame 200 through display device 100; For example: desktop, film etc., and this moment, control module 7 can execution in step S20.
Step S20; Control module 7 control handover modules 5 couple first transmission interface 2 and second transmission interface 3; Make peripheral unit 300 to carry out communication with external main frame 200, in the case, peripheral unit 300 can be as the peripheral equipment of the external main frame 200 of control; Promptly control mouse, the keyboard of PC; The associated control signal of peripheral unit 300 can be sent to external main frame 200 through second transmission interface 3, handover module 5 and first transmission interface 2, and therefore, the user can control external main frame 200 through peripheral unit 300 and carry out corresponding action; For example: the input of the moving of mouse cursor, keyboard, carry out formula etc., and after external main frame 200 is handled those control signals, can relend and send back display device 100 by video signal line 210 and show.
If in step S10, control module 7 detecting video signal input interfaces 1 do not receive signal of video signal, execution in step S30.
Step S30; Control module 7 control handover modules 5 couple second transmission interface 3 with processing module 6; At this moment, peripheral unit 300 can transform the peripheral equipment into control display device 100 into, and its associated control signal can be sent to processing module 6 through second transmission interface 3 and handover module 5; Make processing module 6 can cooperate the control of peripheral unit 300 and carry out corresponding action, for example: online or play multimedia etc.
In other words; When external main frame 200 was not electrically connected with display device 100, peripheral unit 300 can be the peripheral equipment of control display device 100, and the user can control display device 100 through peripheral unit 300 and carry out corresponding action; In case when external main frame 200 is electrically connected on display device 100; Through the switching of handover module 5, peripheral unit 300 can transform into to controlling the peripheral equipment of external main frame 200, makes the user to control external main frame 200 through peripheral unit 300 and carries out corresponding action; Thus; The user will be not need not connect one group of peripheral equipment to external main frame 200 is extra again, causes the peripheral unit 300 that is electrically connected on display device 100 originally idle, in the use with more convenient and hommization.
What specify is that the signal transmission between display device 100, external main frame 200 and the peripheral unit 300 is not limited only to wired mode, also can utilize Wireless transmission mode to accomplish, and does not exceed with present embodiment.
In sum; Whether display device 100 of the present invention receives the signal of video signal that is sent by external main frame 200 by control module 7 detecting video signal input interfaces 1; And switch the signal transmission path that changes peripheral units 300 through handover module 5; Make peripheral unit 300 can be when external main frame 200 be coupled to display device 100 as the peripheral equipment of control display device 100, and when external main frame 200 is coupled to display device 100 as the peripheral equipment of the external main frame 200 of control, so can save one group of peripheral equipment; In the use with more convenient and hommization, so can reach the object of the invention really.
