Abstract: A display device that achieves both high-accuracy sensing by a touch sensor unit and smooth input using the touch sensor unit is provided. The display device includes a display unit and the touch sensor unit. The touch sensor unit performs touch sensing operation at a different timing from display image rewriting by the display unit, whereby the high-accuracy sensing can be achieved. The display unit has a function of rewriting a display image only in a region that needs to be rewritten. In the case where the entire display region is not necessarily rewritten, the time for the sensing operation by the touch sensor unit can be lengthened, whereby the smooth input can be achieved.

Abstract: An earphone includes a speaker housing; a speaker positioned in the speaker housing; a stem extending from the speaker housing, the stem defining an input surface; a conductive object disposed within the stem; a flexible circuit positioned between the stem and the conductive object; a member positioned between the flexible circuit and the conductive object operable to allow the flexible circuit to move with respect to the stem; a force sensor electrode disposed within the flexible circuit; and a controller operable to determine an input to the earphone using a change in capacitance detected using the force sensor electrode, the change in capacitance corresponding to a non-binary amount of a force applied to the input surface. In some examples, the earphone further includes a touch sensor electrode disposed within the flexible circuit.
