<p>A method of driving a display device makes use of the dynamic variation in the brightness of a surface mode liquid crystal device cell having liquid crystal layer with a non-zero twist angle. It has been found that when the applied voltage across such a cell is decreased, the brightness does not increase smoothly to its new value, but instead rises rapidly, reaches a non-equilibrium maximum value, and then slowly decays to the equilibrium value. According to the present invention, the liquid crystal layer is switched before the equilibrium value of the brightness has been reached, so as to make use of the non-equilibrium increased brightness and so increase the brightness of the display. The present invention also provides a liquid crystal display device having means for driving the liquid crystal layer so as to make use of the dynamic variation in the brightness of the liquid crystal device. <IMAGE></p> |
