Abstract

The embodiment of the invention discloses an array substrate, a preparation method thereof and a display panel, the array substrate comprises a photosensitive transistor and a switch transistor, an active layer of the photosensitive transistor comprises a first photosensitive active layer, an active layer of the switch transistor comprises a second photosensitive active layer, and the thickness of the second photosensitive active layer is smaller than that of the first photosensitive active layer; or, the active layer of the photosensitive transistor comprises a first photosensitive active layer, and the active layer of the switch transistor is not provided with a second photosensitive active layer. The array substrate provided by the embodiment of the invention has the advantages that a shading layer does not need to be prepared above the active layer area of the switching transistor to improve the switching performance of the switching transistor, a photomask manufacturing process is reduced, and a shading layer is reduced, so that the preparation cost of the array substrate and the preparation cost of the display panel are reduced.

Description

technical field [0001] The invention relates to the display field, in particular to an array substrate, a preparation method thereof, and a display panel. Background technique [0002] Low-cost and low-power photodetectors have been widely used in smart products, and transistors composed of oxide semiconductor layers and photosensitive material layers are usually used as control devices for photosensors. [0003] In the embedded touch panel, the switching transistor and the photosensitive transistor as the control device of the photosensor are prepared at the same time, and the photosensitive material is sensitive to light, and the electrical property of the switching transistor will change when it is illuminated. Therefore, it is often necessary to A light-shielding layer is prepared above the active layer of the switch transistor to prevent the influence of light on the electrical performance of the switch transistor, which increases the cost of the photomask and preparati...
