摘要： In a touched position detection method for a touch panel for detecting a touched position, based on measured values by a plurality of sensors, presence of a touch is determined when a measured value by a sensor exceeds a touch threshold. As a touch threshold, a value which cannot be attained due to a mere noise but can due to presence of a touch is set. With respect to sensors located in the vicinity of a sensor showing a high measured value, a higher weighted value is applied to modify a measured value in a touched position calculation process than that to be applied to other sensors.

摘要： A static capacitance type touch panel, a control unit electrically connected with X and Y electrodes for detecting a touch position based on a measured value of a static capacitance between the X and Y electrodes. The control unit includes a predetermined touch threshold for detecting a peak, a near-peak range and a non-near-peak range, a first parameter for determining a value of the near peak range, and a second parameter for determining a value of the non-near-peak range. The first and second parameters are respectively predetermined for reduction of a noise influence from the measured value of the static capacitance between the X electrode and the Y electrode.

摘要： Provided is a display device equipped with a touch panel, including a front panel arranged above a capacitive touch panel at a predetermined distance away therefrom, in which the touch panel includes a plurality of X electrodes and a plurality of Y electrodes, and the X electrodes are sequentially applied with pulse signals and the Y electrodes receive the pulse signals. When an arbitrary point on the front panel is touched, the touch panel computes a touched point on the touch panel by using both the received pulse signals obtained from the Y electrodes in a case where the front panel is not deformed and the received pulse signals obtained from the Y electrodes in a case where the front panel is deformed. With this, an erroneous operation in which a measurement value is lowered to finally disappear is prevented.
