What is a Touch Screen and Its Applications?

A touch screen is an electronic input device, usually layered on top of the visual display of an information processing system, that gives a user control of the device through simple or multi-touch gestures. Touch screens allow a user to control a device by interacting with the display itself, rather than requiring an external controller such as an attached mouse or trackpad.

Touch screens can guarantee an accurate, fast response when a user interacts with it on your device. They can be used with a bare finger or a stylus, and can support multi-touch features such as two-finger zoom controls, and in some cases even three-finger or four-finger controls. While most are non-tactile, they can be made with tactile feedback in mind as well.

Touch screens are durable: they're easy to clean and are made to be resistant to harsh cleaning materials, which is important considering how many people could interact with it in any given use case. In addition to chemical resistance, touch screens can be designed to withstand high and low temperatures, moisture and humidity, and dust exposure.

They're built to last long, as well. Touch screens can withstand being tapped or written on in the same area 100,000 times, and the touch screen as a whole can be used up to 1,000,000 times.

Touch screens add a modern and innovative design to products, so it's no wonder why they're the norm for user interface controls for devices in nearly all industries.

Touch Screen Applications

While we've all likely interacted with touch screens the most through our smartphones, touch screens are used in a wide breadth of applications across all industries. Touch screens can help make user experience smoother while operating a device, and can save medical personnel precious time and frustration in life-saving situations.

Some examples are:

Public Information Kiosks

Amusement Products

Consumer Electronics

Voting Machines

Point-of-Sale Systems, like self-checkout kiosks at grocery stores or small business payment systems such as Square

Medical Devices

Industrial Controls

Different types of touch screens are ideal for different applications and use cases.
