Touch Sensitivity
Touchscreens have become indispensable features in modern devices and applications, providing an intuitive user experience. They can be used in a wide variety of ways, from navigation to data entry and control; their sensitivity determines how accurately and responsively they register input—this factor ultimately determines the overall effectiveness and user experience of any system or application.

Touch screens can be made using various technologies, such as capacitive, resistive, infrared, and optical technologies. Each has its own set of advantages and disadvantages; different technologies may better suit different applications. Manufacturers typically select the screen type they offer based on user preference and intended function.
Resistive film touch panels are an economical and reliable option for most applications. They provide users with clear visibility even when touched with fingernails or styluses. Unfortunately, however, these touch panels do not support glove use and may experience interference from nearby metal structures.
Capacitive touch panels use an internal substrate equipped with an IC chip for processing computations, onto which a layer of transparent electrodes has been deposited in specific patterns. As fingers approach the screen, electrostatic capacity changes among electrodes are detected; when one does touch, it triggers a signal indicating its location. The signal then gets processed to initiate a command or action as appropriate.
Larger touch screens act like large antennas, increasing their susceptibility to noise pickup and channel saturation. This can hinder performance by leading to false touches or dropped touches. To mitigate this issue, manufacturers must customize each touch controller based on each application’s objectives, which typically include optimizing SNR, refresh rate, and power consumption.
Touch panels that use LED indicators offer an intuitive user interface for product selection and display control, making these push buttons ideal for audio applications like point-of-sale terminals, showroom displays, and electronic kiosks. Furthermore, such panels can easily be integrated into an AV panel to form a comprehensive solution; an AV 903i Comparator offers customers the chance to select products or change music tracks while shopping.
