Abstract
Provided are a method of removing common noise and a method of detecting touch information. The method of removing common noise includes acquiring base lines, acquiring raw data, calculating touch strengths (TSs) using the base lines and the raw data, calculating a difference representative value between the TSs and a reference level, and removing influence of common noise from the TSs using the difference representative value.
Claims26
A method of removing common noise, the method comprising:
- acquiring base lines;
- acquiring raw data;
- calculating touch strengths (TSs) using the base lines and the raw data;
- calculating a difference representative value between the TSs and a reference level;
- and
- removing influence of common noise from the TSs using the difference representative value.

A method of detecting touch information, the method comprising:
- detecting a touch strength (TS) calculation reference level when there is no touch input;
- detecting touch signals;
- calculating TSs using the touch signals and the TS calculation reference level;
- calculating a difference representative value by calculating a difference between a common noise calculation reference level and the TSs;
- and
- removing influence of common noise from the TSs using the difference representative value.
