Description of the Invention: [Technology of the Invention] [0001] The present invention relates to a computer system. [Prior Art] [0002] Generally, a desktop system includes a display placed on a desktop and a host under the table. The host and the display need to be individually switched or switched by the host to control the display. However, the switch operation is less convenient because the main unit is stored under the table. SUMMARY OF THE INVENTION [0003] In view of this, it is necessary to provide a computer system with convenient switch operation. [0004] A computer system includes a display, a host, and a data line of a data display channel command interface (DDC/CI) protocol. The display is connected to the host through the data line. The display includes an input unit and a microprocessor that supports the DDC/CI protocol. The input unit is for receiving a user operation command. The microprocessor is used to translate user operation commands into a host switch signal. The host includes a power supply unit, a microcontroller that supports the DDC/CI protocol, and a central processor. The power supply unit is configured to provide an operating voltage to the microcontroller and the central processor when the host is not turned on. The microcontroller is configured to receive the host switch signal through the data line and send a request to the central processor after receiving the host switch signal. The towel processor is configured to turn the host on or off according to the switch request. The computer system of the present invention can be conveniently operated by the switch of the main unit (10) of the display. 099113413 Form No. A0101 Page 4/14 Page 0992023652-0 201137619 [Embodiment] [0006] Please refer to FIG. 1, Taigong & The computer system 100 of the preferred embodiment of the present month includes a shoulder device 10, a The host computer 2 and a data line 30 display device 10 supporting the protocol are connected to the host computer 20 via the data line 30. The display 10 includes an input unit 7^12 and a support DD (the VCI determines the microprocessor 14 input unit 12 for receiving user operation commands. The microprocessor 14 is used to convert the user operation commands into a host switch. The host 20 includes a power supply unit 22, a microcontroller 24 supporting the DDC/CI protocol, and a central processing unit 26. The power supply unit 22 is used for the microcontroller 24 when the host 20 is connected to an external power source but not turned on. The operating voltage is provided by the central processing unit 26. Since the microprocessor 14, the microcontroller 24, and the data line 3 both support the DDC/CI protocol, communication between the microprocessor 14 and the microcontroller 24 is possible. The host 20 can obtain display parameters and command requests of the display 1 and send commands to the display 10 to set display parameters, etc. In the embodiment, the microcontroller 24 is configured to receive the host switch signal through the data line 3〇 and receive the signal. The shiver switch signal front_central processor 26 sends a switch request. The central processor 26 is configured to turn the host 20 on or off according to the switch request. Thus, the computer system 100 can be input from the display 1 The switch 12 is controlled by the main unit 12, and the switch operation is convenient. [0007] Please refer to FIG. 2 together, the computer system 1 of the embodiment is a desktop computer system, and the switch operation convenience of the host 20 is on the desktop computer. The system is extremely prominent. Of course, the computer system 10 is not limited to a desktop computer system, but may also be a laptop system, such as a notebook computer. It is also very convenient to switch the host computer through the input unit 12 on the display 10. Operation of the laptop system 099113413 Form No. A0101 Page 5 of 14 0992023652-0 201137619 [0008] The display 10 of the present embodiment is a liquid crystal display including a main frame 16 and a frame disposed in the main frame The display panel 18 in the body 16 and various components (including the microprocessor 14) housed in the frame. The wheeling unit 12 is a plurality of buttons provided on the main frame 16. Since the microprocessor 14 supports the DDC/CI protocol , so it can be programmed to be translated into a host switch signal upon receipt of a particular user operation command output by the input unit 12. For example, the input unit 12 includes a power button 12a After the microprocessor 14 is programmed to determine that the power button 12a is pressed and released quickly, it can be translated into a display switch request; when it is determined that the power button 12a is pressed and maintained for a certain length of time (eg, 3 seconds), the release can be translated into a display switch. Request and host switch signal; when it is determined that the power button 12a is pressed twice and released quickly, it can be translated into a host switch signal. When the microprocessor 14 receives the display switch request, it will issue a display switch command to turn the display 10 on or off. After detecting the host switch signal, the host switch signal will be sent to the host 20 through the data line 30. Of course, the display 1 is not limited to the present embodiment', and it may be other types of display devices. The input unit 12 can be used in other embodiments, such as an on screen display (OSD) on the touch screen. [0010] The main unit 20 includes a chassis 28 and is housed in the chassis 28. Various components (including power supply unit 22, microcontroller 24, and central processing unit 26). The power supply unit 22 can include a voltage converter 22a that converts the voltage of the local power source (eg, AC 2〇〇v) into the microcontroller 24 and the central processing unit 26 after the host 20 is connected to a local power source (not shown). Working voltage. The microcontroller 24 may employ a baseboard management controller (BMC) that is in standby with the central processing unit 26 after being in electrical communication with the power supply unit 099113413, form number A0101, page 6 of 14 0992023652-0 201137619 22 (standby) mode. Generally, the operating voltage of the microcontroller 24 and the central processing unit 26 in the standby mode is about 3. 3V, and the power consumption is small. The microcontroller 24 is connected to the central processing unit 26 via a system management bus (SMBus) and sends a switch request to the ten central processor 26 through the system management bus 2a. The central processor 26 will issue a host switch command upon receiving the switch request to turn the host 20 on or off. [0011] Specifically, the display 10 and the host 20 each include a data interface 32. The data lines 30 are coupled to the two data interfaces 32, respectively, to connect the display 1 to the host 20. The negative interface 3.2 can be: video graphics adapter (VGA/D-stib), digital visual interface (Ml) or high definition multimedia (interface). [0012] Ο Generally, the display 10 further includes an indication unit 12, which is coupled to the microprocessor 14 for indicating the state of the switch 10 and the host 3 of your switch. Thus, the user can recognize the switch state of the host 20 from the pointing unit on the display 10. Specifically, the microcontroller 24 uses the BMC to identify the power-on state of the host 20, and sends the switch state of the host 20 to the microprocessor 14 through the data line 30. The microprocessor 14 can also recognize the switch state of the display 10, which is based on The switch state of the host 20 and the switch state of the display 10 are indicated by the control instructing unit 12b. In the present embodiment, the indicating unit 12b is a light emitting diode (LED) component disposed on the main frame 16, which may include three colors of LEDs, and when both the host 20 and the display 10 are turned off, Turn off the LED component, in the host 20 alone 099113413 Form No. A0101 Page 7 / 14 pages 0992023652-0 201137619 Display the first color (such as green) when turned on, display the second color (such as blue when the display ίο is turned on separately ), a third color (such as red) is displayed when the host 20 and the display 10 are all turned on. [0013] In addition, the host 20 generally includes a power button 28a. The power button 28a is connected to the microcontroller 24 for transmitting a host switch signal to the microcontroller 24 when pressed, and is suitable for manually switching the host 20.
