DRIVING METHOD OF AN LIGHT DETECTION PIXEL WHICH DETECTS THE ACCURATE X-RAY IMAGE OF A SUBJECT AND THE DRIVING METHOD OF AN X-RAY DETECTOR WHICH INCLUDES THE LIGHT DETECTION PIXEL

摘要

PURPOSE: The driving method of a light detection pixel and the driving method of an x-ray detector which includes the light detection pixel are provided to accurately accomplish a correlated double sampling function by obtaining a signal and minimizing waiting time until getting offset.;CONSTITUTION: A panel(100) senses X-ray which is emitted from an x-ray generator. The panel comprises a light detection pixel(P) which is formed on the intersection of a gate line(GL) and a data line(DL). A driving part(200) successively sanctions gate signals in the gate lines. A signal processing parat(300) is applied an electric signal from the data line. The signal processing unit part outputs a video signal(VOUT) to outside using a first sample voltage and second sample voltages.;COPYRIGHT KIPO 2012
