Abstract
Disclosed are an array substrate drive circuit, a display module and a display device. The array substrate drive circuit includes: a signal driver configured for receiving a test signal, and generating a drive signal for driving a pixel array according to the test signal; and a signal isolator configured for dividing the drive signal into an even-numbered row drive signal and an odd-numbered row drive signal for driving the pixel array according to a preset control signal to drive the pixel array in rows. Since adjacent metal conductive layers will not output drive signals at the same time, even if the adjacent metal conductive layers are short-circuited, it can be detected during the test, thus improving the yield of the display panel.
