Industrial touch screens are located in almost everywhere that we go. ATMs, self-help kiosks, grocery stores, computers and the closest being our smartphones that we use, are the ones having touch panels embedded in them. It is a technology that detects the gestures of the fingers tapping on the screen and accordingly them fitted mechanism comes into action. It is convenient to use, as one does not have to make use of keyboards, mouse or any other device that can let the panel function. Even if it is a touch panel, it has a computer embedded into that has been mechanized with the information that it gives out to the user and accordingly functions.
Industrial touch screens have become a rage where people want to bring the world under their fingertips and that's what it is coming to be where people are availing all sorts of necessary services and information using touch screen panels. An industrial touch screen panel variants in types, and each has a use of its own. Considering the below information could help you understand the mechanism of each type and how it is used.
• Resistive touch panel – This contains two layers of glass plates which are metallic and conductive. There is a gap between the two layers that has electricity flowing through it. When the outer layer of the screen is touched, the power is accordingly transmitted to the embedded computer, and hence, the commands follow and so allowing the user to make the best use of services. It requires careful handling, and there are times when the gap between both the layers increase and thus not letting the panel transmit information in the right way.
• Capacitive touch panel – This panel has a bright screen as opposed to resistive screen and has a single layer of glass on the surface. There are circuits placed on the inner side of the panel, and then, whenever there is a touch or gesture, the circuit transmits the information the embedded computer. They are known to be durable, and rough handling does not cause much harm to its normal functionality.
• Acoustic wave panel – This panel uses ultrasonic waves that pass over the screen. When you touch the panel, the wave is absorbed and like capacitive screens, the area of touch is detected. It is difficult to maintain and requires a lot of maintenance where a single scratch or ill-treatment can damage it completely.
