Abstract
A capacitive touch screen panel includes top and bottom ITO coated glass sheets that may both be connected to detection electronics (e.g., a controller) by way of a single, normal flexible printed circuit connector. The ITO coated surface of each of the top and bottom glass sheets may face each other and a transparent material such as an optically clear adhesive may be disposed between the top and bottom glass sheets. In some embodiments, a number of spacers may be disposed between the top and bottom glass sheets to maintain a desired gap between the sheets. In other embodiments, the single, normal flexible printed circuit connector may generally reside in a single plane.
