Projected Capacitive: It is not just for Smartphones Anymore

IW2235P-UMost technologies start small then go large. Some technologies are changed in that process. Surface Acoustic Wave (SAW) and Dispersive Signal Technology (DST), for instance, share similarities but one is designed for small screens and the other is meant for large ones. Projected capacitive (PCap) is a case of the former type of technology; it started with small screens and has transitioned into larger formats.

Even at larger sizes, TouchSystems’ PCap touchscreens look and act like smartphones or tablets. The screens are bezel free, meaning that the active touchscreen area extends from edge to edge. In the past, the larger active area might not have mattered, but the advent of multi-touch capabilities and Windows 8 has changed the touchscreen industry.

TouchSystems’ PCap touchscreens, also like smartphones or tablets, feature flush screens. The screen has everything to do with the touch technology; projected capacitive removes the need for extra layers of glass or the spacer dots found in resistive touchscreens. The touch technology affects interactivity, too. PCap is somewhat infamous for its inability to work with gloved fingers. The inability is more of a rumor. Many times, the inability is due to the technology sensor’s settings rather than an innate limitation. TouchSystems’ PCap screens can work with some gloved applications, but it depends on the type of glove.

Unlike smartphones and tablets, TouchSystems’ PCap touchscreens are commercial-grade. The screens can be used in public environments, such as medical offices and light manufacturing. They are designed to withstand heavy use and to provide a longer life than consumer-grade products.

Projected capacitive isn’t just for smartphones anymore. It’s for large-format, commercial-grade touchscreens, too.
