The power conversion module 73 and the power input bee are integrated inside the display device 97. The first interface 71 receives the serial signal packet from the host computer, and after being processed by the signal conversion module 72 as an image signal and an audio signal, it is directly transmitted to the audio processing module inside the display device 97, and the internal touch of the display device 97 The control signal will also be directly transmitted to the signal conversion module π processed as a serial signal packet 'output to the host computer via the first interface 71, 10 M381945 not two additional configuration transmission lines and connection 75 from the external power supply 85 to obtain lightning = transmission power input After the power conversion module 73 converts the 2 power, it will send it directly to the display device source line to transmit the power. Μ丨厶Electrical conversion, Ϊ ^See the i, the USB interface sound image of the creation of the audio signal of the fourth embodiment of the specific embodiment of the system architecture shows lightly connected to the computer 2 8 ^ use examples, power transmission The power source 75 is directly connected to the power supply 82 to obtain the power supply power 'converted to the power supply by the power conversion module 73; Video and audio weaving _ device = : ' can transmit signals and power supply at the same time, so that == In summary, the video of the creative video signal is set by all the transmission lines of the host computer and the display device to a single universal The serial bus transmission is transferred to the computer main unit. The second device is equipped with a power conversion module to generate power supply; = internal parallelization, and has plug-and-play effect. This makes it a convenient and humanistic practical creation. This is an excellent description of the above. It is only for the purpose of this creation and the drawings. It is not intended to limit the detailed description of the present application. The scope of any patent application below is subject to the scope of any patent application. In the field of work, it is easy to think about changes or the scope of patents defined by the artist in this case. 7 Check can be covered in the following M381945 [Simple description of the diagram] The first diagram is a schematic diagram of the system architecture of the connection system between the computer host and the display device of the prior art; the second picture is the USB interface of the audio and video signal of the creation.
