When it comes to military environments, one issue arises repeatedly; viewability. The need to have the maximum clarity and purest blacks is often a key demand. So how does this impact touchscreens? Well, most touchscreen technologies, aside from IR, require some sort of coating on the surface of the touch interface, or glass that can affect the degree of light transmission. Ah yes, you say, but military displays almost always need some sort of coating anyway, don’t they? Well yes, this is indeed often the case. However, the layers needed to make the touchscreen operate are typically thicker and less optically pure than the specialized filter lays used by the military. For example, the ITO layers used in PCAP touch components can reduce optical transmissibility by up to 30%. Touchscreens that use pure glass are the option to be considered when clarity is a high priority. These are typically traditional IR, and they present their own challenges. |
