摘要： Provided is a pixel sensing circuit, including a signal generation sub-circuit, a reset sub-circuit, an amplification sub-circuit, and a read sub-circuit. The reset sub-circuit is configured to provide a signal of a first power supply line to a first node under control of a reset signal line. The signal generation sub-circuit is configured to detect a light signal and convert the detected light signal into an electrical signal. The amplification sub-circuit is configured to provide an amplified electrical signal to a second node according to a signal provided by a second power supply line and under control of the first node. The read sub-circuit is configured to output the amplified electrical signal to a signal read line under control of a scan signal line.

摘要： The present disclosure provides a detection substrate, a manufacturing method thereof and a ray detector. The detection substrate includes: a base substrate; a plurality of independent first electrodes arranged on the base substrate on the same layer; a photoelectric conversion layer arranged on a whole face of sides, facing away from the base substrate, of the plurality of first electrodes; a ray absorption layer arranged on a side, facing away from the plurality of first electrodes, of the photoelectric conversion layer, wherein an orthographic projection of the ray absorption layer on the base substrate is overlapped with an orthographic projection of gaps between the first electrodes on the base substrate; and a second electrode arranged on a whole face of a side, facing away from the plurality of first electrodes, of the photoelectric conversion layer.
