Abstract
An electro-optic display includes an electro-optic medium, a pixel electrode for applying an electric field to the medium and a column electrode associated with the pixel electrode. To reduce power consumption, when it is necessary to change the voltage on the column electrode from a first value to a second value to change the optical state of the electro-optic medium, the column electrode voltage is first changed to a third value intermediate the first and second values to permit charge to flow to or from the column electrode, and thereafter the column electrode voltage is changed from the third voltage to the second voltage.
Claims6
A flexible large area electro-optic display system comprising:
- a large area light-transmissive flexible substrate;
- a plurality of flexible electro-optic display units attached as tiles to the large area light-transmissive flexible substrate such that the flexible electro-optic display units are oriented for viewing through the large area light-transmissive substrate,
- wherein the flexible electro-optic display units each comprise a front transparent electrode and back pixel electrodes, a plurality of electrically charged particles disposed in a fluid and capable of moving through the fluid under the influence of an electric field, and a display module driver device;
- and
- a global input module operatively connected to the display module driver devices of the plurality of flexible electro-optic display units, wherein the global input module is configured to receive image data from an outside source and to distribute a portion of the image data to each of the display module driver devices.
