摘要
In a method for increasing accuracy of touch coordinate calculation in a capacitive multi-touch system, it performs operations on obtained data for de-noising of the obtained data and increasing its linearity so as to generate data with excellent stability and linearity. An integral accumulation operation is performed to generate data for each sensing channel, cancel the accumulation error in data, and calculate coordinates for touch points on a capacitive touch panel.
