TOUCH SENSING APPARATUS AND METHOD THEREOF
Abstract:
There are provided a touch sensing method and a touch sensing apparatus that can minimize the influence of noise due to a driving signal of a display apparatus. The touch sensing method includes generating an analog signal by sensing variations in capacitance generated from a plurality of electrodes; measuring a first time required for a level of the analog signal to reach a first reference value; determining whether the first time is included in a noise generation period of a driving signal of a display apparatus; and measuring a second time required for a level of the analog signal to reach a second reference value when the first time is included in the noise generation period.
