Description

monitor

The invention relates to a display, in particular to a display that can supply the power required by a computer host.

In recent years, Type-C Universal Serial Bus (USB Type-C) has become one of the main equipment for displays, and USB Power Delivery (PD) has grown from the initial 5W to 100W, which is enough to supply the power required for the operation of the personal computer host. However, the current display does not provide the power required by the computer host under certain circumstances, such as when the user presses the power switch of the display to turn off the display. This makes the host computer unable to be fully powered by the display, and still has to rely on other power sources.

Therefore, the purpose of the present invention is to provide a display.

Therefore, the display of the present invention is suitable for electrically connecting to a computer device. The display includes an input unit, a panel unit, a display terminal transmission port, a control unit and a power supply unit. The display end transmission port is used to connect to the computer device. The control unit is electrically connected to the input unit, the panel unit and the display terminal transmission port. The power supply unit is electrically connected to the input unit, the panel unit, the display end transmission port and the control unit and is used for supplying power required by the input unit, the panel unit, the display end transmission port and the control unit.

After the control unit completes the handshake with the computer device in the powered-on state, when the control unit is receiving an image data from the computer device and to be displayed by the panel unit via the display terminal transmission port, and the control unit passes through the input unit Upon receiving a shutdown input, the control unit controls the panel unit to turn off, and controls the power supply unit to provide the computer device with power required for the computer device to be in a boot state through the display terminal transmission port.

In some implementations, after the control unit completes the handshake with the computer device in the boot state, when the computer device is in the boot state and the control unit has not received the computer device from the display terminal transmission port and is For the image data displayed by the panel unit, the control unit controls the panel unit to turn off, and controls the power supply unit to provide the computer device with power required for the computer device to be in a power-on state through the display terminal transmission port.

In some implementations, after the control unit completes the handshake with the computer device in the pre-shutdown state, when the computer device is in the shutdown state and the control unit has not received the computer device from the display terminal transmission port and will be For the image data displayed by the panel unit, the control unit controls the panel unit to close, and controls the power supply unit to provide the power required for the computer device in a shutdown state to the computer device through the display terminal transmission port.

In some embodiments, after the control unit completes the handshake with the computer device in the standby sleep state, when the computer device is in the sleep state and the control unit has not received the computer device from the display terminal transmission port and is For the image data displayed by the panel unit, the control unit controls the panel unit to turn off, and controls the power supply unit to provide the power required by the computer device in a sleep state to the computer device through the display terminal transmission port.

In some implementations, after the control unit completes the handshake with the computer device in the standby dormant state, when the computer device is in the dormant state and the control unit has not received the computer device from the display terminal transmission port and will be For the image data displayed by the panel unit, the control unit controls the panel unit to turn off, and controls the power supply unit to provide the power required by the computer device in a sleep state to the computer device through the display terminal transmission port.

In some implementations, the display end transmission port is a C-type universal serial bus transmission port.

The effect of the present invention is that when the control unit is receiving the image data from the computer device to be displayed by the panel unit through the display terminal transmission port and the control unit receives the shutdown input through the input unit, the The control unit controls the panel unit to turn off, and controls the power supply unit to provide the computer device with the power required for the computer device to be turned on through the display terminal transmission port, so that even if the user manually inputs the shutdown input through the input unit, the The display can still continue to provide power to the computer device when the computer device is turned on.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are represented by the same numbers.
