Each of the panel capacitors is sequentially selected as an object capacitor. The first switching unit and the second switching unit switch the voltages received by the two terminals of the object capacitor. The control unit controls a first charging current provided by the first charging unit according to the variation in the terminal voltages of the object capacitor, and generates a comparison signal accordingly. The counter counts the comparison signal and the touch panel identifies the variation in the capacitance value of the object capacitor by using a count value generated by the counter."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch panel","description":"A touch panel including a plurality of panel capacitors, a first switching unit, a second switching unit, a first charging unit, a control unit and a counter is provided.
