TFT-PIN ARRAY SUBSTRATE AND ASSEMBLY STRUCTURE FOR FLAT-PANEL X-RAY DETECTOR

Abstract

A TFT-PIN array substrate and an assembly structure for a flat-panel x-ray detector are provided to overcome the problem that the conventional scintillator substrate and TFT-PIN array substrate are neither penetrated by UV-light nor assembled by UV curable LOCA. The metal layer of the PIN photodiode of the TFT-PIN array substrate is perforated to have at least one hole, whereby UV-light can pass through the TFT-PIN array substrate to cure UV curable LOCA. Therefore, UV curable LOCA can be used as an adhesive layer in the assembly structure of a scintillator substrate and a TFT-PIN array substrate to promote the detective quantum efficiency and image quality of a flat-panel X-Ray detector.
