Abstract
A liquid crystal display (LCD) includes a plurality of thin-film-transistor (TFT) LCD elements arranged in a plurality of rows, a respective one of the TFT LCD elements including a liquid crystal element having a pixel electrode and a common electrode, a storage capacitor having a first electrode and a second electrode connected to the pixel electrode, and a transistor having a controlled electrode connected to the pixel electrode and a gate electrode which controls current through the controlled electrode. A common electrode voltage is applied to the common electrodes of the liquid crystal elements of the plurality of TFT LCD elements. A respective gate driving voltage is applied to the gate electrodes of a respective row of the TFT LCD elements and to the first electrodes of the storage capacitors of another row of TFT LCD elements other than a first row of TFT LCD elements. A periodic driving voltage is applied to the first electrodes of the storage capacitors of the first row of TFT LCD elements, the periodic driving voltage having a magnitude and a DC bias sufficient to operate the first row of LCD elements according to a first predetermined transmittance characteristic. Related circuits and methods are also discussed.
