Abstract

The invention discloses a TFT, a manufacturing method, an array substrate, a display panel, a driving method, and a display device, and relates to the field of display technology, in order to solve the problem of large overall power consumption of the display device. The TFT includes a base substrate, on which a first gate, a bottom gate dielectric layer and an insulating layer are sequentially stacked, a source and a drain are arranged on the insulating layer, and a source and a drain are arranged on the base substrate. A top gate dielectric layer, a second gate and a passivation layer are sequentially stacked on the insulating layer; the first gate or the second gate is a photosensitive material gate. The TFT and the display panel provided by the invention are applied to a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a TFT and a manufacturing method, an array substrate, a display panel, a driving method, and a display device. Background technique [0002] At present, display devices are more and more used in people's work, study and entertainment. When users use display devices in different scenarios, the intensity of ambient light around the display devices in different scenarios is often different. In order to be able to adjust For the brightness of the display screen of the display device, an ambient light sensor is often installed in the display device, and the brightness information of the ambient light is obtained through the ambient light sensor, and the brightness information is provided to the processing module of the display device, and the processing module performs the processing according to the acquired brightness information. The brightness information of the ambient light is ...
