Embodiment Construction

[0019] The present invention will be described in detail below with reference to the drawings and embodiments.

[0020] Refer to figure 2 , 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. It can be coupled to and communicate with an external host 200 such as a personal computer or a notebook computer. 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 (two as an example in this embodiment), a hub (HUB) 4, and a switch Module 5, a processing module 6 and a control module 7.

[0021] 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 Interfa...

Abstract

The invention discloses a display device and a control method thereof. The display device comprises a video input interface, a first transmission interface which is coupled with an external host machine, a second transmission interface which is coupled with a peripheral device, a switching module which is coupled with the first transmission interface and the second transmission interface, a processing module which is coupled to the switching module, and a control module which is coupled with the processing module and the video input interface, wherein the video input interface is coupled with the external host machine and used for receiving an image signal which is sent by the external host machine; the control module detects whether the video input interface receives the image signal; if the video input interface receives the image signal, the control module controls the switching module to couple the first transmission interface and the second transmission interface, so the peripheral device can communicate with the external host machine; and if the video input interface does not receive the image signal, the control module controls the switching module to couple the second transmission interface and the processing module, so the processing module correspondingly operates under the control of the peripheral device.

Description

Technical field [0001] The invention relates to a control method, in particular to a control method of a display device. Background technique [0002] Refer to figure 1 , The existing network multimedia display device 900 is usually configured with multiple transmission interfaces (such as USB, not shown), which can be coupled with a first peripheral device (such as a mouse or keyboard, etc.) 910 to provide users with a first The peripheral device 910 controls the display device 900 to perform functions such as surfing the Internet or playing multimedia, but sometimes, the user will also connect an external host (such as a personal computer) 920 to the display device 900 for use, and the external host 920 usually also has a mouse or keyboard Wait for the second peripheral device 930. Therefore, in the case of connecting two sets of peripheral devices, the display device 900 will only allow one set of peripheral devices to operate, that is, the second peripheral device 930, so tha...
