Illustratively, the conversion component 115 is configured to connect or disconnect the first power detection point 113 and the second power detection point 114. Specifically, the conversion component 115 is a material capable of passing an electrical current. In the case that both ends of the conversion component 115 are respectively contacted with the first power detection point 113 and the second power detection point 114, a power line between a display interface of the first display device and a display interface of the second display device is turned on, and current is normally transmitted. At this time, whether or not an abnormality occurs in the current transmission state between the display interface 200 of the first display device and the display interface 300 of the second display device may be detected by a detection device, for example, an ammeter or voltmeter, or the like. In the case that the two 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 interface 200 of the first display device and the display interface 300 of the second real device is disconnected, and the current cannot be normally transmitted. At this time, whether or not an abnormality occurs in the current supply of the display interface 200 of the first display device or the display interface 300 of the second display device may be detected by a detection device, for example, an electronic load instrument or the like.
In summary, the display interface power detection apparatus provided in the embodiment of the present disclosure includes: a power supply test unit; the power supply test unit includes: the power supply connecting wire, the first detection point, the second detection point and the conversion component; the first detection point is communicated with the first display device through a power connection line, the second detection point is communicated with the second display device through a power connection line, and the conversion assembly is respectively connected with the first power detection point and the second power detection point; the conversion component is used for enabling the first power supply detection point position and the second power supply detection point position to be connected or disconnected.
