摘要： An image detecting device has a large dynamic range that deals with a plurality of image detecting modes. The image detecting device is composed of pixels e (i, j) arranged in a matrix array. Each pixel has a photoelectric element. In each pixel, a capacitor 102 and a protecting diode 103 are disposed. The capacitor 102 stores electric charge corresponding to the intensity of penetrated light to the relevant pixel. The protecting diode limits the capacitance. A bias voltage is supplied to the protecting diode 103 through a bias line Bias. The bias voltage is adjusted by a bias voltage controlling system 133 corresponding to the frame rate. Thus, the influence of a leak current in the off-state of the protecting diode 103 can be alleviated against electric charge stored in the capacitor 102. Consequently, an image with a high S/N ratio can be obtained regardless of the frame rate.

摘要： An X-ray semiconductor detector has a pixel array structure in which a plurality of pixel elements are arrayed in a matrix. Each pixel element includes an X-ray/charge conversion film for generating charges in accordance with an incident X-ray, a storage capacitor for storing the signal charges generated in the X-ray/charge conversion film, a signal read transistor for reading the signal charges from the storage capacitor, and a protective diode arranged to remove excessive charges from the storage capacitor and prevent dielectric breakdown of the signal read transistor. The protective diode is arranged below the storage capacitor. Since the protective diode is arranged below the storage capacitor, it does not decrease the pixel density. Since the protective diode is covered with the storage capacitor, it can be shielded from an X-ray. Therefore, variations in OFF current of the protective diode by an X-ray and dielectric breakdown of the protective diode can be prevented.

摘要： Signal output of an X-ray-electric conversion layer prevents instability of operation due to variation of a threshold voltage of TFT mounted to read a signal. Pixel electrodes 17 are arranged in an array on the X-ray-electric conversion layer. Variation of the threshold voltage (Vth) is suppressed by applying in compensatory manner a voltage pulse for switch-off having a polarity opposite to an average polarity of a voltage for switch-on at operating period to the gate electrode of a field effect type TFT for pixel switching connected to each pixel electrode to read a signal.
