Abstract: A drive scheme is described for a display capable of gray scale. Multiple two-level pulses are used in conjunction with dynamic relaxation techniques to write pixels ON or OFF and to adjust the gray level of pixels. Only two voltage levels are used, a maximum level U, and a minimum level 0. This reduces the complexity of the electronics so that the only one voltage generator is needed for the display.
