A touch screen computer is the integration of an output and input device onto a non-intrusive screen. The touch screen is usually combined on the front of an integrated data processing device with a touch sensitive display. The screen is most often an LED or LCD screen while the unit is most often a tablet, laptop, or smartphone.

Touchscreens are fast becoming the preferred method of input devices for consumers. Although touch screen screens are quickly becoming standard in all kinds of consumer electronics and business usage, the reasons they are so popular are due to their excellent response time, high levels of sensitivity, and extended functionality. The rapid adoption of touch screen technology has led to lower cost of devices as well as faster performance and enhanced image clarity. The three types of touch screen technologies are resistive, capacitive, and infrared. Each one has its own advantages but there are also some drawbacks when using these types of touch screen panels.

Resistive touch screens use electric charge to alter the state of the display from “off” to “on”. This is typically implemented with resistive liquid crystal displays (LCD). Because touch screens change their states based on finger motion, resistive touch screens are ideal for applications that require random access and constant interaction with the user. However, resistive touch screens can be sensitive to finger crud which can cause slow response times and screen tearing.

Capacitive touch screens use physical pressure from a finger to change the display from “off” to “on”. Like resistive touch screens, capacitive touch screens are perfect for applications that require random access and constant interaction with the user. However, capacitive touch screens can be sensitive to finger grease, fingerprints, and other contaminants that can affect the response time of the tablet. Because of this, a finger can sometimes slow down the response of the tablet.

Infrared touch screens are another alternative to touch screens. Although not as commonly used as a stylus, an infrared finger sensor can be used as a pointing device or for other purposes. Unlike with the mouse, an infrared finger sensor doesn’t require direct contact between finger and computer mouse; therefore, it is perfect for all kinds of touch screen applications.

While touchscreens have their advantages and disadvantages, they will most likely become the standard in kiosks. Touchscreens are more convenient and more comfortable than any other kiosk technologies available. They can also save you money, provide higher productivity rates, and make interaction with your computer easier. When choosing a touch screen for your business, make sure you research all the different technologies to choose the one that works best for your specific needs.
