However, limited to the transmission bandwidth of USB, the conventional video output 埠120 can only be used to transmit low-resolution video, such as Video Graphics Array 'VGA', but cannot support the current popular video. High-resolution digital video transmission, such as 1080P High Definition Multimedia Interface (HDMI) video. Therefore, 'the need for a new type of computer docking station, which saves the user's troubles', allows the user to enjoy the display of high-definition video. PNAI-AC-0009-TWXX/0814-A42686-TW/Final 201235819 SUMMARY OF THE INVENTION The present invention provides a computer docking station for connecting a computer with a plurality of computer peripheral devices, including a wireless display. (Wireless Display, WiDi) module for receiving video output of the wireless output of the computer; and a video output port for outputting the video received by the wireless display module to an external display. [Embodiment] Hereinafter, the preferred embodiment of the present invention will be described. The examples are intended to illustrate the principles of the invention, but are not intended to limit the invention. The scope of the invention is defined by the appended claims. FIG. 2 is a schematic diagram of a computer docking station according to an embodiment of the present invention. As with the prior art, the computer docking station 200 of the present invention is used to connect a computer with a plurality of computer peripheral devices, including a universal serial bus (USB) input port 210 and a plurality of external outputs. 230. The USB input port 210 is connected to the computer and transmits data to the computer in a "wired" manner, and the external output port 230 is coupled to a plurality of computer peripheral devices, and is also "wired". The way to transfer data with these computer peripherals. It must be noted that although the main purpose of the computer docking station is to facilitate the user of the notebook computer, it is not limited to use on a notebook computer, and various computers supporting the USB output are in the computer docking station of the present invention. Within the scope of application. The external output ports 230 of the present invention may be an audio output port, an RJ-45 output port, a USB output port, a PS/2 output port, a parallel output port, and a serial port output port. For example, the audio output port 230 can be used to connect a speaker or an audio, and the RJ-45 output port 240 is used to connect to a network data machine, and the USB port is PNAI-AC-0009-TWXX/0814-A42686-TW/Final 4 ' ' 201235819 Output ^ 皋 can be used (four) connected to the keyboard, mouse, external patch, printer, camera and other computer peripherals that support USB transmission. Those skilled in the art can change the type and quantity of the above-mentioned rounds in the computer docking station according to the spirit of this month. - Unlike the prior art, the computer docking station 200 of the present invention further includes a Wireless Display (WiDi) module 27A and a video output port 280. The wireless display module 27 of the present invention can receive the video "wireless" of the computer through a wireless receiving device such as an antenna, and the video output port 280 is used to receive the video received by the wireless display module module 27. Output to an external display 290. It is worth noting that the operation of the present invention includes the use of the wiDi technology provided by Intel Corporation. When the computer supports the WlDl technology, it can transmit the screen display content to the present by wireless communication through the Wi-Fi connection. The wireless display module 270 of the invention. In one embodiment, the video output port 280 of the present invention may be a Video Graphics Array (VGA) interface or a Digital Visual Interface (DVI) interface. However, in the preferred embodiment, the video output 280 of the present invention is a High-Definition Multimedia Interface (HDMI) output, if the video received by the wireless display module 270 is HDMI. The signal, then the video output 280 of the present invention can output the HDMI signal to an external display. In a preferred embodiment, in order to maintain optimal display performance, the computer docking station 200 of the present invention can check whether the wireless display module 280 of the computer docking station 200 has been connected when the USB input port 210 is connected to the computer. The driver is installed and automatically installed when the check finds that it is not installed. PN A1-AC-0009-TWXX/0814-A42686-TW/Final 5 201235819 The driver of the module 280 is displayed. Alternatively, in another embodiment, the computer docking station of the present invention can check (4) whether the no-show module of the brain docking station takes a new driver's call at the USB input port 并 21 and when the check finds that the driver is not updated. The driver of the wireless display module 280 is automatically updated. In the preferred embodiment t, the computer docking station of the present invention further includes a proximity sensor H (not shown) for automatically starting the wireless display module 27 when the f brain approaches the computer docking station 200 () And then display the video content through an external display. In accordance with the general usage habits, the output of the computer expansion unit 230 will be frequently connected to other computer peripheral devices. The USB input device 21G will repeatedly connect and disconnect the notebook computer. Whenever the USB input is measured, the transmission line connected to the computer is connected to the computer. The peripherals of the connected computer can be directly connected to the computer and enabled. However, in some cases, the user may only want to make the money and temporarily trap other peripheral devices, and the proximity sensor of the present invention can help the user without inserting the transmission line into the usb input port 210. , the external display can be automatically activated. The computer docking station 200 of the present invention can also provide users with high-definition video display effects by eliminating the trouble of connecting the user's peripheral devices one by one. In addition, since the video transmission on the computer's docking station does not pass through the USB input port 210, the bandwidth of the USB transmission can be greatly saved, which is more conducive to improving the communication performance between the computer and peripheral devices. The present invention has been described with respect to the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention, and the skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
