Abstract
A touch sensing device includes a touch switching unit including first and second touch members, an oscillator circuit generating a first oscillation signal having a variable resonant frequency based on an application of a touch to the first touch member, and generate a second oscillation signal having a variable resonant frequency based on an application of a touch to the second touch member; a detector circuit generating a first count value by converting the first oscillation signal to a first digital value, and generating a second count value by converting the second oscillation signal to a second digital value, detect an individual touch input based on the first count value and the second count value, and detect a slide touch input when a first touch input to the first touch member and a second touch input to the second touch member are detected within a predetermined slide reference time.
