    Abstract: In one embodiment of the present invention, the image display period of the first sub frame of an N-th frame is arranged to partly overlap the image display period of the second sub frame of the N-th frame and the image display period of the second sub frame of the (N?1)-th frame. Also, in each sub frame, a period in which grayscale display voltages are written into all horizontal lines of the display screen is arranged to be identical with the image signal input period of one frame of an input image signal. In addition, the grayscale display voltages with which pixels that are horizontally or vertically neighbored are charged are arranged to have inverse polarities, and the polarity of the grayscale display voltage charging each pixel is reversed in each frame. Furthermore, a short circuit period is provided and in this period neighboring data signal lines are short-circuited each time the polarity of the grayscale display voltage output to each data signal line is reversed.

  • Publication number: 20090001275
    Abstract: An image detection device has an image detector equipped with a detection section having a charge generation section that receives irradiation of electromagnetic waves and generates charges, a storage capacitor in which two electrodes are disposed so as to oppose one another and which accumulates charges generated at the charge generation section, and a TFT switching element for reading out charges accumulated in the storage capacitor. At a time before a point in time of reading out of charges from the storage capacitor via the switching element of the image detector, a reference potential of the storage capacitor is varied by a variable Cs power source, and leak current sufficiently flows before reading out of a charge signal from the image detector. Leak current is thereby reduced sufficiently at a time of reading out the charge signal.
