Title:
DETECTION SUBSTRATE AND FLAT PANEL DETECTOR
Document Type and Number:
WIPO Patent Application WO/2023/208149
Kind Code:
A1
Abstract:
Disclosed in the present disclosure are a detection substrate and a flat panel detector. A detection area of the detection substrate comprises a plurality of pixel units, which are distributed in an array, each pixel unit comprising a thin-film transistor, a photoelectric conversion device, a first bias voltage line and a compensation capacitor, wherein a bottom electrode of the photoelectric conversion device is electrically connected to a source electrode of the thin-film transistor, and the first bias voltage line is electrically connected to a top electrode of the photoelectric conversion device; and the compensation capacitor comprises: a bottom electrode, a dielectric layer, which is arranged on the side of the bottom electrode that faces a base substrate, and a compensation electrode, which is arranged on the side of the dielectric layer that faces the base substrate. In a peripheral area, the detection substrate comprises: a plurality of first conductive layers, which are arranged on the same layer as the compensation electrode, and a second bias voltage line, which is arranged on the same layer as the first bias voltage line, wherein at least one first conductive layer is electrically connected to at least one column of compensation electrodes, the second bias voltage line is electrically connected to the first bias voltage line, and the first conductive layer is electrically connected to the second bias voltage line.
