The CHPI data port 152 refers to a port through which a timing control signal of a CHPI data format is transmitted.
For example, if the output interface of the display screen core 20 is an ISP interface, the output interface of the display screen core 20 may be connected to the ISP data port 146 of the P2P interface 112 of the first signal conversion module 110 to realize the connection between the display screen core 20 and the first signal conversion module 110, so that the display screen core 20 may transmit the original test signal to the first signal conversion unit 116 through the ISP data port 146, convert the original test signal into the standard test signal through the first signal conversion unit 116, and transmit the standard test signal to the second signal conversion module 130. The second signal conversion module 130 is adapted to the display screen 30 to be tested, so that the second signal conversion module 130 establishes a communication connection with the display screen 30 to be tested, and then the second signal conversion module 130 can convert the standard test signal to output the test signal, and transmit the output test signal to the display screen 30 to be tested, so that the display screen 30 to be tested is lighted according to the output test signal, thereby facilitating the maintenance personnel to test the point screen of the display screen 30 to be tested, and realizing one-board point multi-screen, thereby improving the universality of the P2P interface 112 of the first signal conversion module 110, so that the adapter plate 10 of the present application can be applied to all display screen cores 20 without being limited by the types of the display screen cores 20, and can be used for testing the display screens of all models without being limited by the types of the display screens, and further improving the testing universality of the adapter plate 10.

It should be noted that the voltage value of the first power signal is determined by the voltage value output by the display screen movement 20, the voltage value of the second power signal is determined according to the conversion characteristic of the power conversion unit 122, and the voltage value of the second power signal is usually a preset fixed value.
Illustratively, the first power interface 118 includes a first power port and a first ground port; the second power interface 124 includes a second power port and a second ground port.
