Abstract
Provided are a detection substrate and a ray detector. The detection substrate includes: a base substrate; a plurality of detection pixels located on the base substrate, at least one detection pixel serves as a detection marking pixel. The detection marking pixel includes: a storage capacitor, a first electrode plate of the storage capacitor coupled to a bias voltage end; a discharge circuit configured to write a signal of the bias voltage end into a second electrode plate of the storage capacitor under the control of a first scanning signal end; and a reading circuit coupled to an external reading circuit, the reading circuit configured to write the voltage of the second electrode plate of the storage capacitor into the external reading circuit and write a reference signal of the external reading circuit into the second electrode plate of the storage capacitor under the control of a second scanning signal end.
