Selecting a touch panel for an LCD-based product? Here are some basic points to consider:Optical Performance
Choices in glass type, thickness, applied ITO and anti-reflective coatings will all affect panel transmissivity and thus, its optical performance.
Consider that EMI-sensitive and/or RF-intensive products may require countermeasures which may adversely affect optical performance, weight, thickness and cost.
Know the user profile and mode-of-use model. Remember to consider potential use outside of specifications.
Weigh carefully the temperature, humidity, NEMA, IP or other rating requirements against specified capabilities.
