Filed: 2020-06-11
Abstract: To prevent erroneous detection of a touch operation on a touch panel in various environments.SOLUTION: In a touch panel apparatus having an operation surface employing a resistance film system, an abnormal contact operation detecting unit detects, as an abnormal contact operation, a multi-touch operation detected through an operation surface allowing a single-touch operation to be effective and a single-touch operation detected through an operation surface allowing a multi-touch operation to be effective. When any abnormal contact operation is detected, a sensitivity control unit adjusts sensitivity of the operation surface so that any abnormal contact operation should not be detected. By way of example, when the multi-touch operation is detected through the operation surface allowing the single-touch operation to be effective, the sensitivity control unit controls an amplifier for amplifying a signal generated by an operation on the operation surface and supplying the signal to the abnormal contact operation detecting unit, to decrease the amplification factor of the amplifier. When the single-touch operation is detected through the operation surface allowing the multi-touch operation to be effective, the sensitivity control unit controls the amplifier to increase the amplification factor.SELECTED DRAWING: Figure 7
