LCD dust seals and touch screen dust seals are the most basic requirement of display gasketing. These are often static (not portable), indoor applications where the device is not to be exposed to water. Sealing can be achieved by closed cell sponge materials or fine pore open cell materials such as PORON urethane foam.

Light leaking is sometimes a concern with certain LCD or LED display applications. This can be addressed with black gasketing with either a very thin adhesive or a black supported adhesive. A common material configuration for this is soft PORON urethane foam with 3M 9795B adhesive. The 3M 9795B is a film supported double coat adhesive with a black PET support layer that does not pipe light.

It is important to keep in mind the clamping loads. While wider gasket walls generally seal better, the overall surface area is directly related to the loads applied to the LCD and touchscreen. Compression Force Deflection curves of various materials are available to aid designers.

Bearing in mind the traditional benefits associated with solderless connectors, with not employing heat seal bonding equipment and in allowing for very low profile connections, let us look at the three techniques for connection LCD modules to PCBs:

N.B. One should consider methods to achieve and maintain registration of the flex circuit pads with the pads of the module and the PCB. Mechanical details of the substrates should be provided when consulting on design.

Digital graphic touch screen overlays transform any large display into a state-of-the-art interactive touch screen and whiteboard. Touch Screen Overlays attach to the front of your existing LCD, TFT, or Plasma display monitor giving it instant touch interaction with your device transforming your display into a Human Machine Interface. Touch Screen Overlays can provide an excellent way to seal your display from dust, particulate contaminants, and moisture ingress up to IP67 with proper design.

In addition to our many product capabilities, at Dyna-Graphics, we provide fully customized touchscreen panel overlays for your interactive touchscreen needs. Our capacitive and resistive touch screen overlay systems allow for complete interactive capabilities with any type of Plasma, TFT, or LCD display monitor.

We can provide complete, built-to-spec touch screen assemblies to complement your custom touch screen panel overlays. Manufactured to match your design exact specifications, these touch screen assemblies include all the parts and components the module needs:

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.
