The update method includes: acquiring a temperature value of an environment of the touch screen; when determining that the acquired temperature value is less than a preset temperature threshold and determining that a continuously touched area exists in the touch screen, collecting N data frames of the continuously touched area; calculating N feature values of the N data frames; and updating N reference values corresponding to the N data frames according to the N feature values; wherein, N is greater than 1 and N is an integer. A difference between a reference value and a sensed value of the continuously touched area may not be decreased with a temperature rise due to the heat transferred by a touched object, thus point elimination at a low temperature is avoided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic device, touch detection circuit and update method for reference value of touch screen","description":"An electronic device, a touch detection circuit and an update method for a reference value of a touch screen are provided.
