A finger-heating effect has been observed on mutual capacitive touch sensors with plastic film overlay. The symptom is exhibited as serious sensitivity degradation when there is a greater than 10°C ...

This article describes many of the design and application challenges that must be faced when integrating projected-capacitive touch into a device, with a particular focus on the importance of the ...

With the introduction of the first smartphones in 2012 with in-cell touch displays, a battle is emerging between the traditional supply chain of ITO-based touch sensors that are externally combined ...

This file type includes high resolution graphics and schematics. Capacitive touchscreens have increasingly become mainstream and are no longer a novelty. Their adoption continues to grow as devices ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...
