Processing Method And Device of Touch Signal, And Flat Panel Display Using It

摘要

A method and a device for processing touch information and a flat panel display using the method and the device are disclosed. The touch information processing arrangement includes: generating sensor output data from a touch sensor array; computing the sensor output data corresponding to each of adjacent frames to generate difference data; first binarizing the difference data based on a predetermined first threshold value; filtering the first binarized difference data; and second binarizing the filtered difference data based on a predetermined second threshold value.
