具体实施方式 detailed description

下面结合附图及实施例对本发明进行详细说明。The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

参阅图2，为本发明显示装置的较佳实施例，该显示装置100为一具有可直接上网及多媒体播放功能的显示器，其可与一如个人电脑或笔记型电脑的外接主机200耦接并进行通讯，在本实施例中，显示装置100包含一视讯输入接口1、一第一传输接口2、至少一第二传输接口3(本实施例以两个为例)、一集线器(HUB)4、一切换模块5、一处理模块6及一控制模块7。Referring to Fig. 2, it is a preferred embodiment of the display device of the present invention. The display device 100 is a display with direct Internet access and multimedia playback functions, which can be coupled with an external host 200 such as a personal computer or a notebook computer and To communicate, in this embodiment, the display device 100 includes a video input interface 1, a first transmission interface 2, at least one second transmission interface 3 (this embodiment takes two as an example), a hub (HUB) 4 , a switching module 5 , a processing module 6 and a control module 7 .

视讯输入接口1提供与外接主机200的一视讯信号线210电连接，其可为视频图形阵列(VideoGraphicsArray，VGA)、数字视讯接口(DigitalVideoInterface，DVI)、高清晰度多媒体接口(HighDefinitionMultimediaInterface，HDMI)等，用以接收一由外接主机200所发送的影像信号。The video input interface 1 provides an electrical connection with a video signal line 210 of the external host 200, which can be a Video Graphics Array (Video Graphics Array, VGA), a Digital Video Interface (Digital Video Interface, DVI), a High Definition Multimedia Interface (High Definition Multimedia Interface, HDMI), etc. , for receiving an image signal sent by the external host 200 .

第一传输接口2用以提供与外接主机200的一资料传输线220电连接，使显示装置100可与外接主机200相互传输资料及信号；各第二传输接口3分别用以提供与一外围装置300的一信号传输线310电连接，使得显示装置100可配合外围装置300的控制而执行对应的动作，在本实施例中，两外围装置300分别为一鼠标(Mouse)及一键盘(Keyboard)，且第一传输接口2及第二传输接口3皆为通用串行总线(UniversalSerialBus，USB)接口，但皆不以本实施例为限。The first transmission interface 2 is used to provide an electrical connection with a data transmission line 220 of the external host 200, so that the display device 100 can transmit data and signals with the external host 200; each second transmission interface 3 is respectively used to provide a peripheral device 300 A signal transmission line 310 is electrically connected, so that the display device 100 can cooperate with the control of the peripheral device 300 to perform corresponding actions. In this embodiment, the two peripheral devices 300 are respectively a mouse (Mouse) and a keyboard (Keyboard), and Both the first transmission interface 2 and the second transmission interface 3 are Universal Serial Bus (USB) interfaces, but both are not limited to this embodiment.

集线器4耦接于所述第二传输接口3，用以提供多个第二传输接口3连接设置，使所述外围装置300可与显示装置100互动。切换模块5为一个1对2解多工器(DEMUX)，其输入端耦接于集线器4，两输出端则分别耦接于第一传输接口2及处理模块6，用以切换外围装置300的信号传输路径，但切换模块5并不仅以解多工器为限。处理模块6耦接于切换模块5，用以处理外围装置300所传送的信号，并于一显示模块(图未示)显示。控制模块7耦接于切换模块5及视讯输入接口1，用以控制切换模块5切换外围装置300的信号传输路径。特别说明的是，在另一实施例中，显示装置100也可以只设置一个第二传输接口3与单一外围装置300电连接，在此设计下，显示装置100将可不需要集线器4，只要将第二传输接口3直接与切换模块5耦接即可。The hub 4 is coupled to the second transmission interface 3 for providing a plurality of second transmission interfaces 3 connection settings so that the peripheral device 300 can interact with the display device 100 . The switching module 5 is a 1-to-2 demultiplexer (DEMUX), its input terminal is coupled to the hub 4, and its two output terminals are respectively coupled to the first transmission interface 2 and the processing module 6, for switching the peripheral device 300 signal transmission path, but the switching module 5 is not limited to the demultiplexer only. The processing module 6 is coupled to the switching module 5 for processing the signal transmitted by the peripheral device 300 and displaying it on a display module (not shown). The control module 7 is coupled to the switch module 5 and the video input interface 1 for controlling the switch module 5 to switch the signal transmission path of the peripheral device 300 . In particular, in another embodiment, the display device 100 may also be provided with only one second transmission interface 3 to be electrically connected to a single peripheral device 300. Under this design, the display device 100 does not need the hub 4, as long as the second The second transmission interface 3 can be directly coupled with the switching module 5 .

接着，以下将配合图3说明本实施例的显示装置100是如何切换外围装置300的信号传输路径，以充分利用外围装置300，减少其闲置时间，增加使用上的方便性。Next, how the display device 100 of this embodiment switches the signal transmission path of the peripheral device 300 to make full use of the peripheral device 300 , reduce its idle time, and increase the convenience of use will be described below with reference to FIG. 3 .

步骤S10，控制模块7侦测视讯输入接口1是否接收到由外接主机200所发送的影像信号，若是，则表示视讯输入接口1与外接主机200的视讯信号线210电连接，使用者可通过显示装置100来显示外接主机200的画面，例如：桌面、影片等，且此时，控制模块7会执行步骤S20。Step S10, the control module 7 detects whether the video input interface 1 has received the image signal sent by the external host 200, if so, it means that the video input interface 1 is electrically connected to the video signal line 210 of the external host 200, and the user can display The device 100 displays the screen of the external host 200, such as desktop, video, etc., and at this time, the control module 7 executes step S20.

步骤S20，控制模块7控制切换模块5将第一传输接口2与第二传输接口3耦接，使得外围装置300可与外接主机200进行通讯，在此情况下，外围装置300会作为控制外接主机200的周边设备，即控制个人电脑的鼠标、键盘，外围装置300的相关控制信号会通过第二传输接口3、切换模块5及第一传输接口2而传送至外接主机200，因此，使用者可以通过外围装置300来控制外接主机200执行相对应的动作，例如：鼠标游标的移动、键盘的输入、执行程式等，并于外接主机200将该些控制信号处理后可再借由视讯信号线210传送回显示装置100显示。In step S20, the control module 7 controls the switching module 5 to couple the first transmission interface 2 to the second transmission interface 3, so that the peripheral device 300 can communicate with the external host 200. In this case, the peripheral device 300 will act as a control external host The peripheral equipment of 200, that is, the mouse and keyboard that control the personal computer, and the related control signals of the peripheral device 300 will be transmitted to the external host 200 through the second transmission interface 3, the switching module 5 and the first transmission interface 2. Therefore, the user can The peripheral device 300 is used to control the external host 200 to perform corresponding actions, such as mouse cursor movement, keyboard input, program execution, etc., and after the external host 200 processes these control signals, the video signal line 210 can be used. It is sent back to the display device 100 for display.

若在步骤S10中，控制模块7侦测视讯输入接口1并未接收到影像信号，执行步骤S30。If in step S10, the control module 7 detects that the video input interface 1 does not receive an image signal, execute step S30.

步骤S30，控制模块7控制切换模块5将第二传输接口3与处理模块6耦接，此时，外围装置300会改作为控制显示装置100的周边设备，其相关控制信号会通过第二传输接口3及切换模块5而传送至处理模块6，使得处理模块6可配合外围装置300的控制而执行对应的动作，例如：上网或播放多媒体等。Step S30, the control module 7 controls the switching module 5 to couple the second transmission interface 3 to the processing module 6. At this time, the peripheral device 300 will be changed to control the peripheral equipment of the display device 100, and its related control signals will pass through the second transmission interface. 3 and the switching module 5 to transmit to the processing module 6, so that the processing module 6 can cooperate with the control of the peripheral device 300 to perform corresponding actions, such as surfing the Internet or playing multimedia.

换句话说，当外接主机200未与显示装置100电连接时，外围装置300会为控制显示装置100的周边设备，使用者可以通过外围装置300来控制显示装置100执行相对应的动作，一旦当外接主机200电连接于显示装置100时，通过切换模块5的切换，外围装置300会改作为控制外接主机200的周边设备，使得使用者可以通过外围装置300来控制外接主机200执行相对应的动作，如此一来，使用者将不需要针对外接主机200额外再接一组周边设备，造成原本电连接于显示装置100的外围装置300闲置，在使用上将更为方便及人性化。In other words, when the external host 200 is not electrically connected to the display device 100 , the peripheral device 300 is used to control the peripheral equipment of the display device 100 , and the user can control the display device 100 to perform corresponding actions through the peripheral device 300 . When the external host 200 is electrically connected to the display device 100, by switching the switching module 5, the peripheral device 300 will be changed to control the peripheral device of the external host 200, so that the user can control the external host 200 to perform corresponding actions through the peripheral device 300 In this way, the user does not need to connect an additional set of peripheral devices to the external host 200, causing the peripheral device 300 originally electrically connected to the display device 100 to be idle, which will be more convenient and humanized in use.

特别说明的是，显示装置100、外接主机200与外围装置300之间的信号传输，并非仅限于有线的方式，也可以利用无线传输的方式来完成，并不以本实施例为限。It should be noted that the signal transmission between the display device 100 , the external host 200 and the peripheral device 300 is not limited to the wired method, and can also be completed by wireless transmission, which is not limited to this embodiment.

综上所述，本发明显示装置100借由控制模块7侦测视讯输入接口1是否接收到由外接主机200所发送的影像信号，并通过切换模块5切换改变外围装置300的信号传输路径，使得外围装置300可于外接主机200未耦接于显示装置100时作为控制显示装置100的周边设备，并于外接主机200耦接于显示装置100时作为控制外接主机200的周边设备，如此将可节省一组周边设备，使用上将更为方便及人性化，所以确实能达成本发明的目的。In summary, the display device 100 of the present invention detects whether the video input interface 1 receives the image signal sent by the external host 200 through the control module 7, and switches and changes the signal transmission path of the peripheral device 300 through the switching module 5, so that The peripheral device 300 can be used as a peripheral device for controlling the display device 100 when the external host 200 is not coupled to the display device 100, and can be used as a peripheral device for controlling the external host 200 when the external host 200 is coupled to the display device 100, thus saving A group of peripheral devices will be more convenient and humanized in use, so the purpose of the present invention can indeed be achieved.
