technical field

The utility model relates to a display, in particular to a display with power supply function.

Background technique

With the development of science and technology, various types of displays have been widely used. However, traditional displays usually cannot be connected to electronic devices, and even if they can be connected to electronic devices, they cannot provide power supply functions.

Nowadays, some monitors also provide USB ports, which can be connected to external electronic devices and provide power to the electronic devices. However, when the monitor is connected to an electronic device with a large load, it cannot meet its power supply requirements. However, if the power supply voltage of the USB interface is increased blindly, energy is often wasted when connecting electronic devices with relatively small loads or not connecting electronic devices.

The utility model discloses a display with power supply function. Not only can it supply power to external devices, but also can choose the corresponding power mode according to the size of the load, which not only meets the needs of large loads, but also avoids energy waste when the load is small.

These and other objects, features, aspects and advantages of the present invention will be clearly understood by those skilled in the art from the following detailed description, which discloses preferred embodiments of the present invention in conjunction with the accompanying drawings.

Description of drawings

FIG. 1 is a schematic diagram of a display 100 of the present invention.

Detailed ways

Referring to FIG. 1 , FIG. 1 is a schematic diagram of a display 100 of the present invention.

The display 100 includes a first power input terminal 101 , a second power input terminal 102 , a multi-power supply control circuit 103 , a port 104 and a panel 105 .

The first power input terminal 101 and the second power input terminal 102 input power to the multi-power control circuit 103 . The first power input terminal 101 and the second power input terminal 102 can be connected to a battery to directly obtain power, or can be connected to a commercial power through a power adapter to obtain power.

The multi-power supply control circuit 103 is used to manage the first power input terminal 101 and the second power input terminal 102, and select a corresponding power supply mode according to the size of the load, such as independent mode, parallel mode, and series mode.

Independent mode: the multi-power supply control circuit 103 selects an input from the first power supply input terminal 101 and the second power supply input terminal 102 .

Parallel connection mode: the multi-power supply control circuit 103 connects the power input from the first power supply input terminal 101 and the second power supply input terminal 102 in parallel to increase the input current.

Series mode: the multi-power supply control circuit 103 connects the power input from the first power input terminal 101 and the second power input terminal 102 in series to increase the input voltage.

In the above embodiments, two power inputs are taken as an example, but this case is not limited to this, and more power inputs can also be designed according to design requirements, and this case is not limited to this.

The port 104 is used for connecting with an external device 200 . In a preferred embodiment of this case, the port 104 is a USB interface such as USB 2.0, USB 3.0, USB Type C, etc., which can be used for power supply and data transmission. However, this case is not limited to the port 104 being a USB interface, and other types of interfaces that can realize power supply can also be used according to design requirements.

The external device 200 is an electronic device, such as a notebook, a tablet, a smart phone, a host, etc. In this case, there is no special limitation on the type of the external device 200 , as long as the electronic device needs power to operate.

The panel 105 is connected to the multi-power supply control circuit 103, and the multi-power supply control circuit 103 supplies power to it, and the panel 105 is used for displaying images.

The multi-power supply control circuit 103 in this case can detect the size of the load of the display 100 . The load in this case refers to various electronic components in the display 100 that need to obtain power from the multi-power supply control circuit 103 .

The multi-power supply control circuit 103 can select a corresponding power supply mode according to the detected load.

For example, when the port 104 is not connected to the external device 200 , or when the port 104 is connected to the external device 200 and the load is small, the multi-power supply control circuit 103 adopts the independent mode. In addition, when the port 104 is not connected to an external device, the user can also select one input port between the first power input port 101 and the second power input port 102 to connect to a power source, and the other port may not be connected to any power source temporarily.

When the port 104 is connected to the external device 200 and the load is large, the multi-power control circuit 103 can adopt a parallel mode or a series mode to meet the power requirements of the heavy load.

The utility model discloses a display with power supply function. Not only can it supply power to external devices, but also can choose the corresponding power mode according to the size of the load, which not only meets the needs of large loads, but also avoids energy waste when the load is small.

Although the utility model has been disclosed as above with the embodiment, it is not intended to limit the utility model. Anyone with ordinary knowledge in the technical field can make some changes without departing from the spirit and scope of the utility model. and retouching, so the scope of protection of the present utility model should be as defined by the claims.
