Description of the invention () < Field of invention > (Please read the notes on the back before filling out this page) The present invention relates to a USB-to-VGA interface conversion device, especially a computer host and A device that bridges and converts the USB interface port between monitors to the VGA display interface. < Background of the invention and prior art > According to the conventional connection structure between the host computer and the display, the display interface circuit is constructed in the host computer, such as the conventional PCI-type display interface and AGP-type display interface, regardless of the interface, A display interface card must be installed inside the computer host, which not only occupies the interface slot of the computer host, but also relatively increases the equipment and installation costs of the computer host. The connection between the display interface card and the display of the computer host must be multi-pin The multi-pin and multi-pin signal cable connection can enable the VGA display signal in the computer host to be transmitted to the display for display. As a result, the cable diameter between the computer host and the display must be increased, and the number of lines is relatively large. It is not conducive to the configuration and installation of the line, and the increase in the diameter of the line will relatively affect the bandwidth and shrinkage of the line. Limit the length and distance of the line, so that the configuration distance between the host computer and the display must be limited to a narrow range, inconvenient Allocate and use in the user's space, i. Lengthening the laying of the line will attenuate the signal of the line. It is necessary to install additional signal amplifiers and increase the equipment cost of the connection between the host computer and the display. This is the main issue to be solved for the connection between the host computer and the display interface. < Objective and Summary of the Invention > The main object of the present invention is to provide a USB-to-vga interface conversion device 'including at least-a USB control n, a VGA controller and

Description of the invention () and at least one USB socket 330 on the display control circuit board 320 'The USB socket 330 is exposed on the display 300 In addition, the USB connector 510 at the end of the USB connection cable 500 is connected to the USB interface port 210 of the host computer 200 through the USB connection cable 500, and the VGA controller 20 is directly connected to the display The circuit board 320 is controlled to directly provide a VGA display signal required by the display 300. The inventive spirit of the present invention is to use the most streamlined and low-cost technical means to eliminate the need for extra display interface card hardware in the conventional computer host 200, and only the lightweight and simple USB connection cable 500, that is, It can be connected to the display 300, and transmit the required screen display data in a high-bandwidth, low-signal-loss USB interface type and convert it into a relative VGa interface type display signal D or D3 for the display 300 to display, which can greatly reduce the computer host 200 The cost of the connection between the display 300 and the laying cost, and the relative increase in the configuration space and range between the host computer 200 and the display 300, is an invention with great industrial value. The Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the above first to sixth drawings of the USB-to-VGA interface conversion device of the present invention. The disclosed descriptions and diagrams are for the convenience of clarifying the technical content and technology of the present invention. Means, one of the disclosed preferred embodiments, does not limit its scope. In addition, all the technical means, device details, modifications, or equivalent substitutions and replacements of the invention, without departing from the spirit and scope of the invention, will be defined by the scope of the following patent applications * . 10 This paper size applies Chinese National Standard (CNS) 2 丨 〇 < 297 Gongchu
