Embodiment Construction

[0014] Please refer to figure 2 and image 3 , the preferred embodiment of the computer system of the present invention includes a host 30 and a display 40 .

[0015] The host 30 includes a first VGA interface 302 and a motherboard 300. The mainboard 300 is connected to an external alternating current AC through a power supply, and the mainboard 300 can also output different types of voltage, such as 12V. The first VGA interface 302 is disposed on the motherboard 300 for outputting image signals.

[0016] In this embodiment, the first VGA interface 302 includes the first to fifteenth pins 1-15, the first VGA interface 302 is a conventional VGA interface, only the fourth and ninth pins in the first VGA interface 302 And eleven pins 4, 9, 11 are different from the pin definition of conventional VGA interface. Specifically, the first pin 1 is a red signal, the second pin 2 is a green signal, the third pin 3 is a blue signal, and the fifth to eighth pins 5-8 and the tenth pin...

Abstract

A computer system includes a host and a display. The host includes a first video graphics array (VGA) connector. The display includes a second VGA connector and a power supply circuit coupled to the second VGA connector. The second VGA connector is connected to the first VGA connector to acquire power from the first VGA connector.

Description

technical field [0001] The invention relates to a computer system. Background technique [0002] Existing computer system comprises a main frame 10 and a display 20, as figure 1 As shown, the main board 104 of the host 10 is connected to an external alternating current (AC) through a cable, and the power supply circuit 204 of the display 20 is connected to an external alternating current (AC) through another cable. The VGA interface 202 of the display 20 is connected to the VAG interface 102 of the host 10 through the signal line 100 , so that the image signal of the host 10 is displayed through the display 20 . However, when using the computer, the user needs to supply power to the display 20 through the cable alone, which may bring some inconvenience to the user. Contents of the invention [0003] In view of the above, there is a need for a computer system that does not require a separate power cord to power the display. [0004] computer systems, including: [0005]...
