Document Type and Number:
Japanese Patent JP5817695
Kind Code:
B2
Abstract:
A touch detection device includes: an electrostatic capacitance detection device of each touch sensor; and a touch detection device to each touch sensor. The touch determination device obtains a maximum electrostatic capacitance, a minimum electrostatic capacitance and an intermediate electrostatic capacitance, and determines that the touch operation with respect to the touch sensor having the maximum change amount is performed when both of a first condition that a difference between the maximum electrostatic capacitance and the intermediate electrostatic capacitance exceed a second determination value and a second condition that a difference between the intermediate electrostatic capacitance and the minimum electrostatic capacitance is smaller than a third determination value are satisfied, and determines that a change of the electrostatic capacitance is caused by a noise when at least one of the first condition and the second condition is not satisfied.
