When secondary signal transmission apparatus 200 sends blue color difference signal (Pb) and luminance signal (Y) and the first signal biography When defeated device 100 sends red color difference signal (Pr), display unit 40 can show that instruction red color difference signal (Pr) is not inputted Screen 41g, as shown in figure 29.

Because voice signal is also sent through first input end 21a, when not connected first signal transmission device part 100 Voice signal can not possibly be transfused to.Thus, as shown in figure 30, display unit 40 can show instruction sound signal (SL and SR) not The screen 41h of input.

In traditional mode, three cables for sending three component signals are connected to identical out connector.However, According in the signal transmission device part 100 and 200 of example embodiment, one of component signal and composite signal can share one Cable 130a, and remaining component signal is sent through another signal transmission device part 100.

Therefore, when the display screen of display unit 40 during connection to guide the first signal transmission device part 100, user can anticipate The connection for knowing the first signal transmission device part 100 is watched required for the content sent with components method.Correspondingly, it is uncomfortable Can will be outer by the way that signal transmission device part 100 and 200 is suitably used in the user that external equipment is connected to display device 1 Portion's equipment is connected to display device 1, so as to allow user to watch plurality of kinds of contents.

The figure of another example of the screen for the connection that Figure 31 is shown in display device to guide signal transmission device part.

In Figure 27 to Figure 30 above-mentioned example, guided by providing the information relevant with the signal not inputted The connection of signal transmission device part, but the example embodiment not limited to this of display device 1.Correspondingly, can directly provide with The relevant information of signal transmission device part.

As shown in figure 31, display unit 40 can indicate the screen of the outside of the first signal transmission device part 100 by display 41j guides the connection of the first signal transmission device part 100.

Indicating the screen 41j of the outside of the first signal transmission device part 100 can provide and cable 130a, 130b and 130c Number, input connector 110a, 110b and 110c number, the number of out connector 120 and the first signal transmission device part The relevant information of the color of 100 connector.Thus, user can be shown in the screen 41j on display unit 40 by viewing Intuitively to recognize needing which signal transmission device part connected.

Figure 32 and Figure 33 are shown in display device to guide the connection between signal transmission device part and external equipment The figure of the example of screen.

For example, when the lead-out terminal 121 of the first signal transmission device part 100 is inserted into the first input end of display device 1 The lead-out terminal 221 of sub- 21a and secondary signal transmission apparatus 200 is inserted into the second input terminal 21b of display device 1 When, display unit 40 can be guided with display screen 41k by input connector 110a, 110b of the first signal transmission device part 100 The defeated of the second external equipment 3 is connected respectively to the input connector 210a and 210b of 110c and secondary signal transmission apparatus 200 Go out terminal 3a, 3b, 3c, 3d and 3e, wherein lead-out terminal 3a, 3b, 3c, 3d and 3e of the second external equipment 3 and the first signal are passed Input connector 110a, 110b and 110c of defeated device 100 and the input connector 210a of secondary signal transmission apparatus 200 and 210b is corresponding, as shown in figure 32.It can include the connection through additional cable.

For another example, when the first lead-out terminal 121 of the first signal transmission device part 100 is inserted into display device 1 First input end 21a and the second lead-out terminal 221 of secondary signal transmission apparatus 200 is not inserted into display device 1 The second input terminal 21b when, display unit 40 can be guided with display screen 41l by the defeated of the first signal transmission device part 100 Enter lead-out terminal 2a, 2b and 2c that connector 110a, 110b and 110c are connected respectively to the second external equipment 3, wherein second Lead-out terminal 2a, 2b and 2c of external equipment 3 and the first signal transmission device part 100 input connector 110a, 110b and 110c It is corresponding, as shown in figure 33.

Figure 34 is the control block diagram for the controller for showing the display device according to example embodiment, and Figure 35 and Figure 36 It is the figure of the example of the screen for the connection for guiding signal transmission device part.

With reference to Figure 34, controller 300 may further include signal identification unit 330, and it is configured as recognizing signal Form, the signal is whether to be connected to signal transmission device part 100 based on first input end 21a and the second input terminal 21b Determine what is inputted after image output mode with 200.

For example, when the first signal transmission device part 100 is connected to first input end 21a and secondary signal transmission apparatus 200 when being not attached to the second input terminal 21b, and pattern determining unit 310 can determine that image output mode is output composite diagram The first mode of picture.

However, in fact, the first signal transmission device part 100 may be coupled to the second external equipment 3 of output component signal Without connected to the first external equipment 2 of output composite signal.

In this case, because three component signals one of them be input into signal processor 320, work as signal Processor 320 handle the input signal but without change and by processed signal include on display unit 40 when, do not have There are colour difference information or the image without monochrome information to be displayed on display unit 40.

Thus, signal identification unit 330 will can be exported and through the first signal transmission device part from the second external equipment 3 The signal identification of 100 transmission is component signal, and it is second that pattern determining unit 310, which can redefine image output mode, Pattern --- wherein it is not connected with secondary signal transmission apparatus 200, rather than first mode.

In this case, display unit 40 can guide secondary signal transmission apparatus 200 with display screen 41m and 41n Connection, as shown in Figure 35 and Figure 36.

When the first signal transmission device part 100 sends luminance signal (Y) in component signal, display unit 40 can pass through Text is shown to show the screen 41m, such as Figure 35 that indicate that blue color difference signal (Pb) and red color difference signal (Pr) are not transfused to It is shown, and display unit 40 can show the screen 41n for the outside for indicating secondary signal transmission apparatus 200 to allow user straight See ground and recognize which signal transmission device part needs connection, as shown in figure 36.
