Abstract:
1. An X-ray detector performing an offset stabilization process, an x-ray detection process, and a reset process in each driving cycle, the X-ray detector comprising: a sensor panel including a plurality of pixels each pixel including a photodiode and a switching element, wherein the photodiode converts light corresponding to incident X-ray into an electric signal and the switching element is coupled to one terminal of the photodiode to control the output of the electric signal; a light emitting unit configured to provide light to the photodiode; and a voltage supply unit connected to the other terminal of the photodiode and configured to selectively supply one of a first voltage and a second voltage to the photodiode, wherein the first voltage is different from the second voltage, and wherein the voltage supply unit is configured to:
