Screen Solutions International capacitive touch foils are a projected capacitive touch screen technology that allows users to interact through glass or acrylic surfaces. Projected capacitive technology uses a grid of micro wires that pick up when a finger or capacitive object is used on the surface. Capacitive touch screen technology is something most everyone has used before; most touch screen ATM’s have this type of touch screen built into the display.
Projected capacitive touch screens can sense a user’s touch through glass up to ¾” (20mm) thick. They can even be calibrated to work through double glazed windows, glass with air gaps, and gloved fingers. Applications vary and no two installations alike, but these are some general guidelines. We have experienced cases where capacitive touch screen foils have worked through glass thicknesses up to 1.5”.
Typical response time for projected capacitive touch foil is 18ms – 50ms (depending on the thickness of glass or acrylic). What this means is that the capacitive touch screen technology can sense a touch on the surface quickly and with accuracy.
Light transmission through the capacitive touch foil surface is generally better than 93%. Light transmission is the amount of light that the object in question stops from passing through to the viewer’s eyes. In this case the capacitive touch foil only stops about 7% of the light passing through it. For a tremendous amount of real world applications, we can tell you that the picture quality will not be affected almost at all. In the last few years, we have never had anyone bring it up.
The capacitive touch foil can be used either in portrait or landscape modes. See the picture above for a brief overview of screen orientation options.
Each capacitive touch foil is made with an active area, and a “tail” (where all the wires attach to the PCB board) that comes off either the side or the bottom of the foil. You can choose to customize the length and position of where your tail comes off of your touch foil by working with our customer service team. Call a representative at 888-631-5880 for more information.
The typical output from the PCB board to the computer is via a mini-USB on the touch foil side to a standard USB Cable on the computer side. This not only delivers power to the touch foils, but transmits touch signal to the provided drivers on your PC or MAC (MAC drivers still in beta only).
Projected capacitive touch foils work with LCD TVs, LED TVs, rigid rear projection screens, and projection film materials. The touch foil generally needs to about 1/2” off the face of a TV to properly calibrate. When using a projection film, apply your touch foil to your display substrate and then apply your projection film to the rear side of your capacitive touch foil.

ProFoil 2 Point - Dual Touch
A 2 Point touch foil gives great responsiveness for projects that are on a smaller scale. If you plan to only have one or two people using the screen at once, then a 2 Point touch foil will give you all the coverage you need at a lower price point. Each 2 Point touch foil comes with roughly 2,000 individual sensors. With a 2 Point Foil, you will be able to easily use the drag, drop, zoom, or even right click gestures just as you would on a standard consumer device. This type of foil is perfect for projects that do not require a large amount of input, such as a “point-and-tap” kiosk. It is also well suited for displays that are used in a presentation style.
If your project is meant to accommodate multiple user interaction, then a 10 Point touch foil may be what you need. By upgrading to a multi-touch format, a 10 Point touch foil has twice the resolution of a 2 Point foil. This allows all 10 points of interaction to be accurately tracked, and allows for a great user experience. Having a 10 Point multi-touch foil gives you access the the same gestures as a 2 Point foil, but with 2 times the accuracy and 5 times the amount of users. This type of foil is typically used in situations that have a consistent level of traffic. Trade show presentations, office conference rooms, and lobby displays benefit greatly from what a 10 Point foil can provide.
For projects that need even more interactivity, the 20 Point touch foil can deliver. The 20 Point touch foil functions identically to the 10 Point foil, but provides double the number of touch points. With a little over 4,000 individual sensors, this foil is perfect for projects where the 10 Point foil does not make the cut. Large trades show presentations, corporate conference rooms, and busy lobby displays are the perfect place to use a 20 Point foil. Having 20 points of touch also allows up to 10 users to simultaneously drag, drop, zoom, or right click as needed.
The 40 Point touch foil is the largest standard foil we have available, and provides the best performance for large-scale or demanding projects. With over 4,000 individual sensors and the ability to have 40 simultaneous points of input, the 40 Point foil allows for accurate tracking over wide display distances. This type of foil is typically used on video walls, high-traffic displays, and interactive presentations. If your project is meant to be consistently in use over a very wide surface area, a 40 Point foil is a perfect fit. With 40 points of touch, your display will give up to 20 users the ability to drag, drop, zoom, or right click independently and at the same time.
Recently released, the 20X Foil takes touch accuracy to the next level. With over 8,000 individual sensors, the 20X Foil has double the resolution of a standard 20 Point Foil. For larger projects that need precise tracking, the 20X Foil is able to deliver. Projects that are on an above-average scale with benefit immensely from a 20X foil. By providing 2 times the amount of individual sensors as a normal 20 Point foil, users will be able to drag, drop, zoom, and right click with even greater precision.
The 40X Foil is the most comprehensive offering we have available. By coming with over 8,000 individual sensors and the capacity for 40 points of simultaneous use, the 40X Foil is the premiere touch foil solution for even the most demanding interactive projects. Having the highest level of precision tracking available, a 40X foil will turn any project into a user’s ideal device. Up to 20 users will be able to simultaneously drag, drop, zoom, and right click with a level of accuracy they would expect from a consumer tablet.
