摘要：
A method for addressing a bistable nematic matrix LCD having two stable textures without any applied electric field. Pixel addressing is of the passive multiplex type. The method includes selecting the value of the electrical voltage applied between the substrates so that an average value of the voltage, preferably the average quadratic value, since the initial command for image display up to the time immediately preceding switching, has a predetermined value independent of the information to be displayed, which is the same for all the pixels of the image.
