Abstract
The disclosure provides a sensing apparatus and an operation method thereof. The sensing apparatus includes a sensing circuit, an analog-to-digital converter (ADC) circuit, a disturbing circuit and an output circuit. The sensing circuit is configured to output a sensing signal indicating a sensing result of a sensing line of the display panel. The ADC circuit is coupled to the sensing circuit to receive the sensing signal and outputs sensing data related to the sensing signal. The disturbing circuit is coupled to the ADC circuit to receive the sensing data and generates a time-variant disturbance component to disturb the sensing data to generate disturbed data. The output circuit is coupled to the disturbing circuit to receive the disturbed data.
