Abstract
A reference data updating method and system for a capacitive multi-touch screen are disclosed. The method includes the steps of step A: one-frame sampling touch detection nodes, calculating a difference between sampled data of each touch detection node and corresponding current reference data and saving the difference as detection data to obtain a current detection data frame; step B: judging whether the current detection data frame is a damaged detection data frame; and step C: executing a touch screen reference update processing procedure under abnormal condition if the current detection data frame is a damaged detection data frame; otherwise, executing a touch screen reference update processing procedure under normal condition. The disclosed method and system can be used in capacitive multi-touch screens fabricated with different materials in different processes and having difference specifications to timely and reliably update the reference data, thereby increasing the reliability of the capacitive multi-touch screens.
