AN ELECTROPHORETIC DISPLAY PANEL

摘要

An electrophoretic display panel having picture elements (64) is provided with a switchable foil element (65). By addressing with a mechanical switch the low threshold voltage of current electrophoretic material need not be a problem. Whether the mechanical switch is open or closed determines whether the pixel is addressed. Preferably the voltage decay time, i.e. RC time of the picture element, is substantially larger than the contact time of the foil element, i.e. the time needed to open and close the mechanical switch provided by the foil element.
