Abstract
A processing system comprises a first source amplifier and an analog front end. The first source amplifier comprises a first input electrically connectable to a first sensor electrode of a display panel and configured to generate a first drive signal based on a first grayscale voltage corresponding to a first pixel data and generate a first comparison output signal based on a first sensing signal from the first sensor electrode and a reference voltage. The analog front end is configured to generate a first digital detection data used for proximity sensing based on the first comparison output signal outputted from the first source amplifier.
