Abstract
A device and method providing a pixel architecture that, in at least one embodiment, contains both an on/off memory element and a switching element to utilize low-power liquid crystal displays for video or near-video applications. Such an embodiment can be implemented, for example, using a pair of TFTs for implementing the memory element and switching element on a common substrate. Other embodiments can utilize actual memory devices for the memory elements. This device and method are particularly useful for driving cholestric display elements for video or near video rate applications.
