Active matrix liquid crystal display device
摘要:
An active matrix type liquid crystal display device wherein a correcting voltage having an absolute value larger than that of a feed-through voltage of the liquid crystal element is applied to a pixel electrode through a storage capacitor, when the liquid crystal has positive dielectric anisotropy and a positive voltage is applied to the pixel electrode, and when the liquid crystal has negative dielectric anisotropy and a negative voltage is applied to the pixel electrode. As the signal voltage value corrected through the storage capacitor can be changed depending on the signal voltage value of the previous field, a voltage to be applied to the liquid crystal can be corrected in advance to emphasize a change in a motion image.
