Motion video cholesteric displays

A video speed driving waveform comprising:

• a. an erasing pulse with its configuration sufficiently activating at least a portion of display's elements to the homeotropic texture;
• b. a bias voltage with its configuration sufficiently maintaining the homeotropic texture and the focal-conic texture;
• c. a “hole” pulse with its configuration sufficiently activating display's elements to focal-conic texture;
• d. a narrow pulse combined with the “hole” pulse activating display's elements at least partially to homeotropic texture;
• e. a waveform sequence:
• first, the frame erasing pulse;
• second, the bias pulse following the erasing pulse and lasting to the end of the frame except being interrupted by the “hole” pulse;
• third, the narrow pulse and the “hole” pulse constantly shifting from one row to another, during a frame addressing with an interval of the narrow pulse pulse-width;
• fourth, the waveform sequence may or may not being repeated immediately by the next frame;
• whereby a video speed display driving scheme with at least 30 frames per second is accomplished.

A display driver's signal logic comprising:

• a. a plurality of data “1” positive single pulse signals;
• b. a plurality of data “0” zero voltage signal;
• c. a scanning negative single pulse signal;
• d. a synchronized signal;
• wherein the data “1” and data “0” signals out of the column driver and the scanning single pulse out of the row driver are synchronized and applied to the display's elements in such a way that the scanning pulse is shifting from the first line to the last line of the display area with the interval of data “1” pulse-width in a video frequency;
• whereby a true binary data generates two-dimensionally optical “ON” and “OFF” states on the display's elements in a video speed.
