REDUCTION OF TFT INSTABILTITY IN DIGITAL X-RAY DETECTORS

A digital radiographic detector uses an IGZO active layer in the switching element for each imaging pixel in a two-dimensional array of imaging pixels. Each imaging pixel has a photo-sensitive element and the switching element. Read-out circuits electrically connected to the two-dimensional array ge...

Zusammenfassung:A digital radiographic detector uses an IGZO active layer in the switching element for each imaging pixel in a two-dimensional array of imaging pixels. Each imaging pixel has a photo-sensitive element and the switching element. Read-out circuits electrically connected to the two-dimensional array generate a radiographic image by reading out image data by switching on and off the switching elements. The IGZO active layer may be formed having a thickness less than about 7 nm.
