RADIATION DETECTOR WITH AN ORGANIC PHOTODIODE

摘要

The present invention relates to a radiation detector with organic photodiodes and to a method of producing such a radiation detector. The TFT backplane (103, 104) is placed between the scintillator (101) and the organic photodiode layer stack (105, 106, 107, 108). This implies the use of transparent TFT-electronics, e.g., a-Si with back-thinned glass or an organic TFT on foil. The geometrical order enables a multitude of possible stack built- ups for OPDs and has advantages for encapsulation and manufacturing.

主权项

1. Radiation detector for an examination apparatus, the radiation detector comprising:
a scintillator for receiving and absorbing incident radiation and for converting the incident radiation into photons; a thin-film transistor prepared on a substrate, the substrate being arranged between the thin-film transistor and the scintillator; a photoactive layer arranged at a side of the thin-film transistor facing away from the substrate.
