Abstract

The invention discloses an array substrate, an array substrate manufacturing method and a display panel. The array substrate comprises a substrate; a thin film transistor which is arranged on the substrate and comprises a grid electrode, an active layer, a source electrode and a drain electrode, wherein the source electrode and the drain electrode are connected with the active layer; and a photosensitive sensor which comprises a photosensitive module and a storage module, wherein the photosensitive module comprises a photosensitive semiconductor layer, and the storage module comprises a first electrode plate and a second electrode plate; wherein the photosensitive semiconductor layer is arranged on the extension part of the drain electrode, the first electrode plate is electrically connected with one side, far away from the extension part of the drain electrode, of the photosensitive semiconductor layer, and the second electrode plate is electrically connected with the drain electrode. The array substrate comprises the photosensitive sensor, the number of film layers of the photosensitive sensor is reduced, the number of manufacturing procedures of the array substrate can be reduced, and a photomask is saved.

Description

technical field [0001] The present application relates to the display field, and in particular to an array substrate, a method for manufacturing the array substrate, and a display panel. Background technique [0002] With the rapid development of the panel industry, in addition to the requirements for high resolution, wide viewing angle, and low power consumption of the display, people also put forward other requirements for the display panel. Enriching panel functions, increasing human-computer interaction, and improving the competitiveness of display panels are one of the main development directions of display panels at present. Integrating the ambient light sensor into the display panel can avoid punching holes in the screen or reducing the size of the screen due to the external ambient light sensor, and avoid affecting the appearance of the screen and the screen ratio. However, the current ambient light sensor integrated in the display panel has many film layers and com...
