摘要： This disclosure provides systems, methods and apparatus for touch sensing on a display device. In one aspect, a method is provided for reducing electrical interference on a display including bi-stable display elements and touch sensing elements without a grounded shielding layer between display elements and touch sensing elements. The method may include placing at least a portion of an array of bi-stable display elements in a selected state with display driver circuitry, maintaining the display elements in the selected state, and obtaining a signal from a touch-sensing element using touch sensing driver circuitry different from the display driver circuitry when the display elements remain in the selected state.

摘要： A method of driving electromechanical devices such as interferometric modulators includes applying a voltage along a common line to release the electromechanical devices along the common line, followed by applying an address voltage along the common line to actuate selected electromechanical devices along the common line based on voltages applied along segment lines. Hold voltages may be applied along common lines between applications of release and address voltages, and the segment voltages may be selected to be sufficiently small that the segment voltages will not affect the state of the electromechanical devices along other common lines not being written to.
