The drive end concurrently inputs encoded and modulated drive signals into a plurality of channels of the capacitive sensing matrix within each drive time slot of a frame. The detection end detects a detection matrix of the channels in the frame and decodes the detection matrix to respectively generate a two-dimensional detection vector corresponding to each of the channels. The detection end further calculates a subtraction between components of the two-dimensional detection vectors associated with two receiving electrodes of the capacitive sensing matrix to eliminate interference from noises."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Capacitive touch system using differential sensing and operating method thereof","description":"A capacitive touch system including a drive end, a capacitive sensing matrix and a detection end is provided.
