The purpose of this Presentation is to give the Audience a basic understanding of capacitive Touch Sensing Technology. It will cover the basic principles of capacitive touch sensing and the stack up of different sensor types. The influence of material and thickness of Cover Lenses and Air Gap will be demonstrated and surface treatment of Cover Lens, AR (Anti Reflection), AG (Anti Glare), AS (Anti Smudge) / AF (Anti Fingerprint) will be explained.
A short introduction to Standard TFT modules with CTP Sensors will be given and a practical demonstration of tuning of a Touch Sensor using different types of Cover Lenses will be given with advices of ‘How to’ and especially ‘How *not* to’ when integrating Capacitive Touch Sensors in a product, based on real examples.
