Abstract: A ray detector substrate has detection regions and includes a substrate, a first interdigital electrode and a second interdigital electrode disposed on a side of the substrate and located in each detection region, a first scintillator layer disposed on a side of the first interdigital electrode and the second interdigital electrode away from the substrate, and a second scintillator layer disposed on a side of first scintillator layer away from the substrate. The second scintillator layer is configured to convert part of rays incident onto the detection region into visible light, and transmit another part of the rays, so that the another part of the rays is incident onto the first scintillator layer through the second scintillator layer. The first scintillator layer is configured to convert the visible light converted by the second scintillator layer and the another part of the rays through the second scintillator layer into photocurrent.

Abstract: A touch substrate, a display apparatus and a display system are provided. By rearranging and distributing transistors in each shift register, the number of transistors in a lateral direction is less than that of transistors in a longitudinal direction. That is a circuit structure of the shift register is designed to extend longitudinally, so that a size of the shift register in the lateral direction can be reduced, a narrow frame design is realized, and seamless splicing is favorably realized in a large-sized display panel.
