Abstract
An embodiment of the present invention discloses an array substrate, a method of fabricating the same, and a display panel. Compared with the conventional technology, the present invention combines a sensing material with thin film transistors to prepare a sensing layer on the thin film transistors, and since the thin film transistors can be formed by a large-area preparation, the sensors can be formed by a large-area preparation accordingly, thereby improving a performance of the sensors and reducing the production cost of the sensors.
