The cover lens, or front surface of a touch panel, represents the look and feel of your product. This is the first surface your customers are likely to engage and possibly where perceptions of quality and user experience start to emerge.

​

Cover lens design elements include:
 

• Material choices based on durability and optical expectations

• Shapes, masking, artwork and logos

• Drilled Holes

• Edge treatments

Touch sensor controller choice is an important element in a well designed touch enabled solution. Not all controllers or makers should be considered equal.  Application, use case and end user experience should define the best design choices.

​

Important considerations include:
 

• Support for rain, chlorinated, salt water and other conductive liquids rejection, heavy glove use, multiple touch points

• Interfacing requirements such as I2c or USB

• Custom flex tail shapes and connection termination type

• Longevity, price points and engineering support

The firmware of the selected controller can be adjusted to ensure the touchscreen delivers the best performance for its intended application. Also known as tuning, firmware modifications may be required to support:

​

• Specific cover lens materials and thicknesses

• Gloved finger inputs of various material types

• Rejection of false touches caused by water droplets or electrical interferences

• Improved immunity to EMI through software filtering

• and other custom use case features
