Drive method for active matrix display device

摘要

A method of driving an "active matrix" display device which is driven by scanning signals to sequentially store and display image signal data by successive rows of picture elements, incorporating for example liquid crystal display elements, whereby the image signal data applied to successive picture element rows (or successive groups of rows) is alternately inverted in polarity about a fixed reference potential. Image-dependent leakage current effects caused by non-ideal characteristics of the matrix switching elements are thereby effectively reduced due to the elimination of low-frequency components other than the reference potential from the image signals applied to each column of display elements.
