Abstract

PURPOSE: To prevent the sensitivity lowering due to the stains caused by the longtime use by using the integrating circuits differing from each other to the electrodes of a touch sensor circuit, and then to ensure an accurate switching by making use of the transient phenomenon only when the human body touches both electrodes at one time.
