Abstract
A matrix display has pixels each including a programmable memory element arranged in parallel across capacitance . The voltage on the capacitance controls a display element . The arrangement can be run in a normal mode, with all of the memory elements in a high resistance state so that the matrix display can be driven dynamically. Alternatively, in a static (low power) mode of operation, the memory elements are programmed with a static image which may be displayed without driving the data lines
