ARRAY SUBSTRATE AND MANUFACTURING METHOD THEREOF, DISPLAY PANEL AND DISPLAY DEVICE

摘要

Disclosed are an array substrate and a manufacturing method thereof, a display panel and a display device. The array substrate (1) comprises a base (10), as well as a data line, a switching device and a voltage compensation module (12) which are arranged on the base, wherein the switching device is connected between the data line and the voltage compensation module (12) and used for connecting the data line with the voltage compensation module (12) when the voltage on the data line is lower than a preset low voltage or higher than a preset high voltage. The array substrate (1) adopts a PN junction as the switching device between the data line and the voltage compensation module (12), and the leakage current between the P end and the N end of the PN junction is low, so that the power consumption of the array substrate can be reduced.
