Abstract
Official abstract text for this publication.
At least one example embodiment discloses a sensor circuit capable of processing a second input signal received via a sensing line by using a demodulation path for performing a demodulation operation or processing the second input signal by using a non-demodulation path that does not perform the demodulation operation, according to a level of a first input signal, for example, a noise signal, received via the sensing line.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating a touch screen sensor integrated circuit (IC), the method comprising: determining if a first input signal output from a capacitive touch screen panel is within a noise window; selecting one of a demodulation path and a non-demodulation path based on the determining; and processing a second input signal output from the capacitive touch screen panel using the selected one of the demodulation path and the non-demodulation path.…
