    • The present invention relates to a driving method of an X-ray detector having an X-ray detection switch, a light extraction capacitor, a light extraction element arranged on an X-ray extraction pixel, and a plurality of gate lines and data lines defining X-ray extraction pixel in matrix arranged along a first and second direction crossed to each other. The driving method comprises the following steps: (a) a current is produced in the light extraction element by visible rays converted from X-ray; (b) the light extraction element and light extraction capacitor send an electric current for two or more gate lines by the X-ray extraction switch for the two or more gate lines; (c) and image signals are outputted from voltage charged in the light extraction capacitor in each gate line. By using the present invention, an image shading phenomenon caused by time difference in reading in each gate line can be prevented, so that an accurate X-ray image of an object can be secured.

    • The present invention relates to a driving method for an X-ray detector which defines X-ray detection pixels in a matrix shape having a light detecting capacitor and a light detecting element connected with a first bias terminal. The driving method comprises as follows: (a) a step of generating current from a light detecting element by visible rays converted from X-rays; (b) a step of charging the current generated from the light detecting element into a light detecting capacitor; (c) a step of outputting an image signal from the voltage charged into the light detecting capacitor; and (d) a step of removing the remaining charge of the light detecting element through a second bias terminal. At this time, to the bias terminal for removing the remaining charge, applied is higher voltage than the voltage applied to the other end of each of the light detecting elements which are not connected with a switch for removing the remaining charge. As a result, the driving method can prevent the ghost phenomenon where a previous image remains in the next image due to the remaining charge in the light detecting element.
    • 本发明涉及一种X射线检测器的驱动方法,该X射线检测器定义具有光检测电容器和与第一偏置端子连接的光检测元件的矩阵形式的X射线检测像素。 驱动方法包括:(a)通过从X射线转换的可见光线从光检测元件产生电流的步骤; (b)将从光检测元件产生的电流充电到光检测电容器中的步骤; (c)从充电到光检测电容器的电压输出图像信号的步骤; 以及(d)通过第二偏置端子去除光检测元件的剩余电荷的步骤。 此时,施加到偏置端子用于去除剩余电荷,施加的电压高于不与用于去除剩余电荷的开关连接的每个光检测元件的另一端的电压。 结果,驱动方法可以防止由于光检测元件中的剩余电荷而使先前图像残留在下一图像中的重影现象。
