ABSTRACT:
An electro-optical display device operating in an active matrix mode, comprising pixels each provided with a first element for selecting the pixel, a second element for supplying electric current to the pixel in accordance with the information transferred from the first element, and a memory element which stores the signal having output from the first element. Also claimed is a method of displaying images using an electro-optical display device operating in an active matrix mode, said method comprising rewriting only the specified pixels, or comprising rewriting only the specified lines during one frame, or comprising taking the period of scanning (addressing) the image plane longer than the period of alternating the polarity of the electric current applied to the pixels.
