ABSTRACT:
Methods and apparatuses for display systems which modulate a control electrode to cause an electro-optic layer to be reset to a state in which display data is not viewable. In one embodiment of the invention, a display system includes a first substrate having a first plurality of pixel electrodes for receiving a first plurality of pixel data values representing a first image to be displayed. The display system further includes an electro-optic layer which is operatively coupled to the pixel electrodes, a control device coupled to at least one of the pixel electrodes and an electrode operatively coupled to the electro-optic layer. The display system displays the first image and then applies a first control voltage to the electrode to alter a state of the electro-optic layer such that the first image is substantially not displayed and then the display system displays a second image represented by a second plurality of pixel data values after the electrode receives a second control voltage. The control device applies a first reference voltage to the at least one pixel electrode before the display system displays the second image. Various other apparatuses and methods are described.
