Design Tip

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.

Electrical Performance

• Consider that EMI-sensitive and/or RF-intensive products may require countermeasures which may adversely affect optical performance, weight, thickness and cost.

Application Dynamics

• Know the user profile and mode-of-use model. Remember to consider potential use outside of specifications.

Operating Environment

• Weigh carefully the temperature, humidity, NEMA, IP or other rating requirements against specified capabilities.
