CAPACITANCE MEASURING DEVICE FOR IMPROVING TOUCH ACCURACY

摘要

According to a capacitance measuring device for improving touch accuracy proposed in the present invention, a comparison unit is included, a capacitance measured by a capacitance measuring unit is compared with a predetermined first reference value or second reference value, and a touch signal is determined to be effective when the measured capacitance satisfies a predetermined condition with respect to the reference value. Accordingly, it is possible to determine whether or not an effective touch is made, and, although a capacitance is changed by noise, it can be determined that an actual touch is not generated, thereby providing high accuracy.
