<p><P>PROBLEM TO BE SOLVED: To provide a driving method of an X-ray detector, and the X-ray detector using the same. <P>SOLUTION: In this driving method of the X-ray detector and the X-ray detector using the method, an X-ray detecting period is a period for generating an electric signal corresponding to an X-ray via a light sensing pixel by receiving the X-ray from an X-ray generator. An offset adjusting period is provided between the two X-ray detecting periods. The light is repeatedly supplied to a photodiode of the light sensing pixel in the offset adjusting period, and a period for turning on a switching element of the light sensing pixel is generated in a period of interrupting supply of the light. Node electric potential for connecting the photodiode and the switching element at the final time of the period of turning on the switching element, is always maintained in a specific value. Thus, distortion of an X-ray image by a deviation of offset voltage can be prevented. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
