Custom Touch Screen Overlays
Digital graphic touch screen overlays transform any large display into a state-of-the-art interactive touch screen and whiteboard. Large Touch Screen Overlays attach to the front of your existing LCD or Plasma display monitor giving it instant touch interaction with complete programing and Internet browsing capabilities. These medical equipment overlays are ideal for hospital computer screens and numerous other industrial applications.
Differences Between Capacitive & Resistive Touch Screen Overlays
There are a few key differences between capacitive and resistive touch screen technologies. A resistive touchscreen is comprised of of several layers, out of which the flexible plastic and glass layers are the two most important electrically resistive layers. When a finger or stylus tip presses down on the outer surface, both the ITO films meet, which leads to an accurate measurement of the touch position.
Resistive Touchscreen Benefits
- High resistance to dust & water
- Low production cost
- Suited for finger, gloved hand or stylus
- Appropriate for hand writing recognition
In comparison, a capacitive touchscreen also consists of two spaced layers of glass, which are coated with conductor such as Indium Tin Oxide (ITO). The human body is then used as a conductor, so when a finger touches the glass of the capacitive surface, it changes the local electrostatic field, which creates the interaction. The system continuously monitors the movement of each tiny capacitor to locate the next area of touch.
Capacitive Touchscreen Benefits
- Bright & sharp display
- Highly sensitive, does not require a stylus
- Supports multi-touch
Touch Screen Overlay Technology
Touch Screen overlays incorporate sophisticated optical imaging technology and a robust design to provide a durable touch solution perfect for high-traffic public applications. The glass overlay preserves the displays optics and protects it from damage or abuse. Touch frame overlays are easy to install and use, making it easy to take your standard screen and convert it to touch screen. In addition, overlay tough technology is designed with a wealth of features to ensure long-lasting durability and functionality.
Dyna-Graphics has been designing, engineering, and manufacturing custom touch screen overlays for more than 45 years. Our touch screen overlays are durable and versatile enough for applications ranging from construction equipment interfaces to medical equipment overlays. Working from your designs, we will deliver touch screen digital graphic overlays that match your unique specifications.

The Custom Touch Screen Overlay Experts
Dyna-Graphics utilizes hard coated lenses in all our custom touch screen overlays and panel displays. These lenses enhance incandescent, LED, fluorescent gas, and liquid crystal displays for superior visibility. Light sources can be exposed or totally sealed, as your application requires.
Two options are available for lighted displays: always on, or “dead front” (viewable only when on or activated). Dead front displays can be adjusted for the strength of the light source.
We can also install multiple light sources in the same switch panel. We can include individual LEDs, fluorescent gas displays, and digital LED displays, as needed.
