Technology
-
Touchscreen monitors are based on three different technologies: resistive, capacitive and surface wave.
Attributes
-
Resistive touchscreens are extremely durable and can be used either with fingers or a stylus, but they lack brightness and clarity. Surface wave technology is the most advanced and displays brighter images, but it also requires more maintenance and care. Capacitive touchscreens have high-quality displays, but they must be tapped with fingers and do not respond to a stylus or pen.
Choice
-
Due to their properties, different touchscreen technologies are better suited for different applications. Factors that determine which touchscreen technology is the best choice include device type, setting, mobility of device, and desired clarity and brightness.
