Description of the Invention: [Technical Field] The present invention relates to a control method, and more particularly to a control method of a display device. [Prior Art] Referring to FIG. 1, the existing network multimedia display device 9 is usually configured with a plurality of transmission interfaces (such as USB, not shown), and can be connected to a first peripheral device (such as a mouse or a keyboard) 910. The user is configured to control the display device 900 to perform Internet access or play multimedia through the first peripheral device 910, but sometimes the user also connects an external host (such as a personal computer) 92 to the display device 900. The external host 92A usually also has a second peripheral device 930 such as a mouse or a keyboard. Therefore, in the case of connecting two sets of peripheral devices, the display device 900 only allows one of the peripheral devices to operate, that is, the second periphery. The device 920 is such that the first peripheral device 91 will be inactive and in an idle state, and such a design is not user friendly.

The video input interface is configured to be coupled to an external host and receive an image signal sent by the external host; the first transmission interface is coupled to the external host 201246152; and the second transmission interface is configured to be coupled to a peripheral device; The switching module is coupled to the first transmission interface and the second transmission interface; the processing module is coupled to the switching module; the control module is coupled to the switching module and the video input interface. The control module detects whether the video input interface receives the image signal, and if so, the control switching module couples the first transmission interface with the second transmission interface, so that the peripheral device can communicate with the external host, so that the user can pass through the peripheral device. To control the external host to perform corresponding actions, such as: mouse cursor movement, keyboard input, execution program, etc.; if not, the control switching module couples the second transmission interface with the processing module to make the processing module Corresponding actions are performed in conjunction with the shackling of peripheral devices, such as surfing the Internet or playing multimedia. Therefore, regardless of whether the display device is coupled to an external host, it can be controlled through the same set of peripheral devices, which is more convenient and user-friendly in use. In addition, the display device further includes another second transmission interface, which is coupled to the other peripheral device, and further includes a hub coupled between the second transmission interface and the switching module. The external host includes a video signal line and a data transmission line. The video wheel input interface is electrically connected to the video signal line to receive the image signal. The first wheel interface is electrically connected to the data transmission line to enable the peripheral device to communicate with the external host. Further, another object of the present invention is to provide a control method which can control the operation of the above display device. The control method of the display device of the present invention is implemented in a display device, and the display device is coupled to a peripheral device. The control method includes the steps of:

In step S10, the control module 7 detects whether the video input interface 1 receives the image signal sent by the external host 200, and if so, the video input interface 1 is electrically connected to the video signal line 210 of the external host 200. The display device 1A displays a screen of the external host 2, such as a desktop, a movie, etc., and at this time, the control module 7 executes step S2. Step S20 The control module 7 controls the switching module 5 to couple the first transmission interface 2 with the second transmission interface 3, so that the peripheral device 3 can communicate with the external host 200. In this case, the peripheral device 3〇 As a peripheral device for controlling the external host 200, that is, a mouse and a keyboard for controlling the personal computer, the relevant control signals of the peripheral device 300 are transmitted to the second transfer interface 3, the switching module 5, and the first transmission interface 2 to The external host 2〇〇, therefore, the user can control the external host 2 to perform corresponding actions through the peripheral device 300, for example, the movement of the mouse cursor, the input of the keyboard, the execution program, etc., and the external host 200 After the control signals are processed, they can be transmitted back to the display device by the video signal line 210. If the control module 7 does not receive the video signal in the control module 7 in step S10, step S3 is performed. In step S30, the control module 7_switching module 5 secretizes the second transmission interface 3 and the processing module 6. At this time, the peripheral device 3 (10) is changed to be a peripheral device for controlling the display device 100, and the related control signal is transmitted through the second The transmission interface 3 and the switching module 5* are transmitted to the processing module 6, so that the processing module 6 7 201246152 can perform corresponding actions, such as surfing the Internet or playing multimedia, etc., in conjunction with the control of the peripheral device 300. In other words, when the external host 200 is not electrically connected to the display device 1 , the peripheral device 300 can control the display device 1 to control the display device 1 by the peripheral device 3 When the external host 2 is electrically connected to the display device ι, the peripheral device 3 改 is changed to control the peripheral device of the external host 200 through the switching of the switching module 5, so that the user can pass through the periphery. The device 300 controls the external host 2 to perform a corresponding action, so that the user does not need to additionally connect a set of peripheral devices to the external host 200, thereby causing peripheral devices 3 that are originally electrically connected to the display device 1〇. It will be more convenient and user-friendly to be idle. In particular, the signal transmission between the display device 100, the external host 2, and the peripheral device 300 is not limited to wired or wireless transmission, and is not limited to this embodiment. 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, and switches the signal transmission path of the peripheral device 300 through the switching module 5. 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 for controlling the external host 2 when the external host 200 is connected to the display device 1 The device will save a group of peripheral devices, and the use will be more convenient and user-friendly. Therefore, the object of the present invention can be achieved. However, the above is only the preferred embodiment of the present invention, when not
