Abstract
Disclosed are an electrostatic capacity change sensing method and apparatus, and a recording medium in which a program executing the method is recorded, a touch sensing method and apparatus, and a recording medium in which a program executing the method is recorded. The electrostatic capacity change sensing method and apparatus are capable of sensing the change in the electrostatic capacity without using the sensing frequency. The touch sensing method and apparatus are capable of sensing touch without using the sensing frequency.
