A display panel detection method and a display panel detection device, the detection method comprising the following steps: storing an image used for detection in a source driver circuit board of a display panel; electrically connecting a power board generating a power signal directly to the source driver circuit board; transmitting the power signal and a clock signal to the source driver circuit board, the clock signal being directly generated by the power board; connecting a data transmission port of the display panel to a serial interface of a computer system, a detection program for comparing a sample image and an image being configured in the computer system; and comparing the pixel consistency of the image and the sample image so as to produce a comparison result.
