US 2013/0170616 A1 · RADIOGRAPHIC DETECTOR INCLUDING BLOCK ADDRESS PIXEL ARCHITECTURE, IMAGING APPARATUS AND METHODS USING THE SAME

Abstract

Embodiments of radiographic imaging systems; digital radiography detectors and methods for using the same can include radiographic imaging pixel unit cells that can include a plurality of N pixel elements that each include a photoelectric thin-film conversion element connected in-series to a conversion thin-film switching element, a conductor connected to the plurality of N pixel elements and an output switching element connected between the conductor and an imaging array output. Scan lines or row lines can extend in a first direction coupled to more than one pixel unit cell and data lines or column lines can extend in a second direction coupled to more than one pixel unit cell.

Dependent claims

A projection radiographic imaging array, comprising:

an insulating substrate;
a scan line to extend in a first direction over the insulating substrate;
a data line to extend in a second direction over the insulating substrate;
and
a thin film pixel unit cell comprising
a first thin film switching element comprising:
a first terminal;
a second terminal electrically coupled to the data line;
and
a control terminal electrically coupled to the scan line,
where the first terminal and the second terminal are electrically coupled based on a scan signal from the scan line;
a plurality of N pixel elements each comprising a photoelectric thin film conversion element and a second thin film switching element, where the photoelectric conversion element and the second switching element are connected in series between a first reference voltage and a first terminal of the first switching element.
