In the touch detection method, coded data is loaded in drive channels and collected from sense channels. The collected data is decoded and subjected to differential processes. This results in a reduced common-mode signal, interference and noise. A touch response detection is carried out to choose at least one sense channel without touch response from sense channels as reference channel. This dynamically chosen reference channel reduces the risk of inaccurate touch location inference caused by abnormalities of static dummy reference channel and helps improve touch location detection accuracy, sense channels close to ends of capacitive touch control device are allowed to participate in touch response detection as other sense channels do, resulting in an expanded touch control range. The touch control chip and touch control display device all have similar advantages."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch detection method, medium, touch control chip and touch control display device","description":"A touch detection method, a touch control chip and a touch control display device are disclosed.
