EL emitting touch switch

An EL emitting touch switch is provided with differential amplifier circuits each including an operational amplifier (41) and resistors (R1, R2, R3, R4) for supplying an electric current to a corresponding surface electrode (1a) so that the potential of the surface electrode (1a) may become equal to...

Beschreibung
Zusammenfassung:	An EL emitting touch switch is provided with differential amplifier circuits each including an operational amplifier (41) and resistors (R1, R2, R3, R4) for supplying an electric current to a corresponding surface electrode (1a) so that the potential of the surface electrode (1a) may become equal to that of a back electrode (1d). While the application of a driving voltage to an EL layer (1) is stopped, a corresponding detector (40) of the EL emitting touch switch detects the contact of a human body with the surface electrode (1a) on the basis of the output signal from the operational amplifier (41).
