    Abstract: The brightness signal for an image display device is digitally processed using an analog to digital converter to translate the signal into digital words. A primary shift register is connected to the output of the analog to digital converter. The primary shift register has a stage capable of containing a digital brightness word for each element in the display line of the device. The primary shift register has a plurality of parallel outputs being spaced X number of stages from each other. Each output is connected to a separate secondary shift register which has X stages.

    Abstract: A unidirectional electric field is applied to selected liquid crystal elements of a display matrix during one display frame. The direction of application of the field is reversed during the next display frame. The above may be achieved, for example, by connecting a capacitor across the liquid crystal element, charging it in one sense during one frame then opening the charging circuit, and charging it in the opposite sense during the next frame and then opening the charging circuit.
