TOUCH SENSING DEVICE AND METHOD THEREOF

摘要

There are provided a touch sensing device and a method thereof. The touch sensing device, including: a plurality of sensing circuit units measuring capacitance variations from a plurality of sensing electrodes; at least one TDC circuit connected with the plurality of sensing circuit units to convert the capacitance variations into digital signals; a calculating unit judging a touch from the digital signals; and a delay circuit sequentially receiving the capacitance variations from the plurality of sensing circuit units.
