摘要： A driving method for driving a polyphase inverter includes: receiving a reference input that includes a fundamental frequency component, and a previously generated feedback signal; generating an error signal that corresponds to a difference between the reference input and the previously generated feedback signal; attenuating the error signal to the minimum; generating an optimum signal; quantizing the optimum signal; and generating driving signals that correspond to the quantized optimum signal. A driving device that implements the driving method is also disclosed.

摘要： The present invention is related to a liquid crystal display element and driving method therefor, particularly to a high image rate supertwisted nematic liquid crystal display elements and driving method therefor. By means of a newly introduced crystal formula, a reduced spacing distance between the first and second substrates, an enlarged pretilt angle of alignment layer, and an accelerated frame rate (frame rate: the number of frames displayed per second) of the driving signal, high response rate display is obtained, and thus image retention and flicker are not showed in the liquid crystal display element, so as to display the dynamic image with the effect of high image quality and fast response time.
