Photosensitive element, display panel, display device and X-ray imaging device
The embodiments of the invention provide a photosensitive element, a display panel, a display device, and an X-ray imaging device. The photosensitive element includes a first top gate type thin film transistor as a control switch and a second top gate type thin film transistor serving as a photosensitive unit. The first top gate type thin film transistor is connected to the second top gate type thin film transistor. A gate of the second thin film transistor includes a transparent region corresponding to at least a part of an active layer of the second thin film transistor, thereby achieving a measurement of a light intensity entering the second thin film transistor when the first thin film transistor and the second thin film transistor are turned on simultaneously.
