Abstract:
1. An X-ray detector comprising: a plurality of light sensing pixels each comprising a photodiode configured to generate an electrical detection signal corresponding to incident light and a switching device for transmitting the detection signal; a gate driver configured to supply a gate pulse to the switching device via a plurality of gate lines, wherein the gate pulse turns on the switching device; and a read out integrated circuit configured to read out the detection signal from the plurality of light sensing pixels, wherein in a scrubbing period, in which a gate scan is performed at least once to initialize the photodiodes of the plurality of light sensing pixels, a plurality of gate pulses are supplied to each gate line during each gate scan, wherein a gate pulse interval having a gate off level is included between the two or more gate pulses supplied to each gate line during each gate scan, and wherein a second of the two or more pulses supplied to a first one of the gate lines is applied at least partially after the fist pulse of the two or more pulses applied to a subsequent one of the gate line.
