Industrial standard displays need to perform under all circumstances – in extremes of weather and temperature, or environments where there is a high risk of damage. Traditionally, this has been fulfilled by resistive touch displays, which are essentially two transparent film layers, each with a conductive layer on the inside. To operate, these layers press against each other. However, this continual pressure can be problematic, as it means they lose their resistance over time and eventually wear out. Scratching and a lack of optical clarity is also an issue.
