Abstract
Methods and systems for operating a display system. An example of the display system includes a first substrate having a plurality of pixel electrodes, an electro-optic layer operatively coupled to the pixel electrodes and an electrode operatively coupled to said electro-optic layer. In one example of a method of the invention, a first plurality of pixel data values is applied to the plurality of pixel electrodes. A first control voltage is applied to the electrode to alter a state of the electro-optic layer such that the first pixel data represented by the first plurality of pixel data values is substantially not displayed. A second plurality of pixel data values, representing a second pixel data, is applied to the plurality of pixel electrodes, and a second control voltage is applied to the electrode to alter the state of the electro-optic layer such that the second pixel data is displayed. In an example of a first aspect of the invention, a voltage difference between the first control voltage and the second control voltage is reduced to reduce capacitive shifting of the second plurality of pixel data values on the plurality of pixel electrodes. In an example of a second aspect of the invention, at least one of the first control voltage, the second control voltage and a pixel data value of the second plurality of pixel data values is determined by an illumination color used in displaying said second pixel data. In an example of a third aspect of the invention, the electrode receives a composite signal over time, and a first parameter of at least one of the first control voltage and the second control voltage is selected to provide an offset, for a portion of the composite signal, from a DC balanced signal over time with respect to a particular voltage.
