Abstract:
The disclosure provides a touch control apparatus and noise compensation circuit and method thereof. The noise compensation circuit includes an integration circuit, a noise storage circuit, and a noise detection circuit. The noise detection circuit receives a plurality of continuous touch detection signals, and compares the touch detection signals with a first and second threshold values to generate a plurality of detection results. The noise detection circuit sets a plurality of noise signals to be saved in the noise storage circuit or transmits a plurality of effective signals to the integration circuit based on the detection results. The noise storage circuit generates an average noise within a time period based on the noise signals and transmits the average noise to the integration circuit. The integration circuit generates a touch detection result according to the effective signals and the average noise.
