Attached Figure Description

[0021] The accompanying drawings are provided to further illustrate the present disclosure and form part of the specification. They are used together with the following detailed description to explain the present disclosure, but do not constitute a limitation thereof. In the drawings:

[0022] Figure 1 This is a schematic diagram of the structure of a display interface power detection device according to an exemplary embodiment;

[0023] Figure 2 It is based on Figure 1 The diagram shown is a structural schematic of a power detection unit;

[0024] Figure 3 It is based on Figure 1 A schematic diagram of another display interface power detection device is shown. Detailed Implementation

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0026] In response, this disclosure proposes a display interface power supply detection device, as follows:

[0027] Figure 1 This is a block diagram illustrating a display interface power detection device according to an exemplary embodiment, such as... Figure 1As shown, the device 100 includes a power testing unit 110; the power testing unit 110 includes a power connection cable 111, a power connection cable 112, a first detection point 113, a second detection point 114, and a conversion component 115. The first detection point 113 is connected to the display interface 200 of the first display device via the power connection cable 111, and the second detection point 114 is connected to the display interface 300 of the second display device via the power connection cable 112. The conversion component 115 is connected to both the first power detection point 113 and the second power detection point 114. The first detection point 113 and the second detection point 114 can be through-hole pad detection points or solder pin detection points.

[0028] For example, the conversion component 115 is used to connect or disconnect the first power detection point 113 and the second power detection point 114. Specifically, the conversion component 115 is made of a material capable of transmitting current. When both ends of the conversion component 115 are in contact with the first power detection point 113 and the second power detection point 114 respectively, the power line between the display interfaces of the first display device and the second display device is connected, and the current is transmitted normally. At this time, a detection device, such as an ammeter or a voltmeter, can be used to detect whether there is an abnormality in the current transmission status between the display interfaces 200 and 300 of the first display device. When both ends of the conversion component 115 are separated from the first power detection point 113 or the second power detection point 114, the power line between the display interfaces 200 and 300 of the first display device is disconnected, and the current cannot be transmitted normally. At this time, a detection device, such as an electronic load tester, can be used to detect whether there is an abnormality in the current supply to the display interfaces 200 and 300 of the first display device.

[0029] In summary, the display interface power detection device provided in this embodiment includes: a power testing unit; the power testing unit includes: a power connection cable, a first detection point, a second detection point, and a conversion component; wherein, the first detection point is connected to a first display device via the power connection cable, the second detection point is connected to a second display device via the power connection cable, and the conversion component is connected to both the first and second power detection points; the conversion component is used to connect or disconnect the first and second power detection points. This allows adjustment of the display interface power supply, thereby enabling detection of both connected and disconnected states of the display interface power supply, improving the detection efficiency and applicability of the detection device.

[0030] Figure 2 It is based on Figure 1 The diagram shown is a structural schematic of a power detection unit, such as... Figure 2 As shown, in one possible embodiment, the device further includes a base plate 120 on which the power testing unit is disposed. The base plate 120 can be a rigid board made of insulating material, preferably a PCB (Printed Circuit Board), which consists of an insulating base plate, connecting wires, and pads for mounting and soldering electronic components, serving the dual function of conductive lines and an insulating base plate. The aforementioned power connection line is disposed on the PCB. The first detection point 113 and the second detection point 114 are both solder pins, which are fixed to the base plate 120, and the lower end of the solder pin is connected to the power connection line.

[0031] For example, the conversion component 115 can be a shorting cap. The two holes of the conversion component 115 can be detachably inserted into two solder pins to achieve communication between the first detection point 113 and the second detection point 114.

[0032] Figure 3 It is based on Figure 1 A schematic diagram of another display interface power detection device is shown, as follows: Figure 3 As shown, the device 100 also includes a male test interface connector 130 and a female test interface connector 140. The male test interface connector 130 and the female test interface connector 140 can be connected to the power testing unit 110 mounted on the base plate 120 via a power connection cable. Alternatively, preferably, both the male test interface connector 130 and the female test interface connector 140 are mounted on the base plate 120 to increase the overall integrity of the device 100 and improve its portability.

[0033] It is understood that the male connector 130 of the test interface is used to mate with the female connector 200 of the first display device. Similarly, the female connector 140 of the test interface is used to mate with the male connector 300 of the second display device. The power pin of the male connector 130 is connected to the first detection point 113 via power connection cable 111, and the power pin socket of the female connector 140 is connected to the second detection point 114 via power connection cable 112. Therefore, after the male connector 130 of the test interface is mated with the display interface 200 (which is the female connector) of the first display device, and the female connector 140 of the test interface is mated with the display interface 300 (which is the male connector) of the second display device, the device 100 can be considered as an intermediate medium connecting the female connector 200 of the first display device and the male connector 300 of the second display device, realizing current transmission between the two.

[0034] In one possible implementation, the first display device is a power receiving end, the second display device is a power supply end, and current is conducted from the second display device to the first display device. Based on this, the conversion component 115 is used to connect the first power detection point 113 and the second power detection point 114, so that either the first power detection point 113 or the second power detection point 114 serves as a detection point for detecting whether there is an abnormality in the current transmission between the display interface 200 of the first display device and the display interface 300 of the second display device. Alternatively, the conversion component 115 is also used to disconnect the first power detection point 113 and the second power detection point 114, so that the second power detection point serves as a detection point for detecting whether there is an abnormality in the current supply to the second display device.

[0035] In summary, the display interface power detection device provided in this embodiment includes: a power testing unit; the power testing unit includes: a power connection cable, a first detection point, a second detection point, and a conversion component; wherein, the first detection point is connected to a first display device via the power connection cable, the second detection point is connected to a second display device via the power connection cable, and the conversion component is connected to both the first and second power detection points; the conversion component is used to connect or disconnect the first and second power detection points. This allows adjustment of the display interface power supply, thereby enabling detection of both connected and disconnected states of the display interface power supply, improving the detection efficiency and applicability of the detection device.
