Touch Screen Integration

Optical bonding

The best touch technology for your application

Selecting the appropriate touch technology for your application can be tricky unless you have first-hand experience with the various options and understand the trade-offs inherent with each. If you’re looking for an industrial display solution, any of our standard industrial monitor products can be customized with either a projected capacitive or resistive-touch screen.

IEE can incorporate any touch screen technology available today into your custom design. In our in-house clean room, we can add touch functionality to almost any LCD panel using either optical bonding (wet) or dry bonding techniques. We work closely with you to select the technology that provides the best features and performance at the highest optical and cost efficiency.
