How to Make the Right Selection for Touchscreen Panels

 In News

We have come a long way after using devices that were operated with keyboards and mice. Today we have millions of products using touch panels as the interface. But do you know what really makes a touch interface system? It is essential to know about this aspect because it plays an important role in the selection of a touchscreen.

The first thing we need to keep in mind is that the success of an application depends on the selection of the right type of touchscreen. Therefore, this significant step can’t be ignored. However, no touchscreen currently available offers a holistic solution. Thus, selecting any touchscreen panel technology is usually a compromise of features and benefits and depends on the particular application and environment.

Having this concern, here’s a guide for buyers, providing the important criteria to allow selection of the most appropriate touch technology for the intended application.

An ideal touchscreen panel should have the following characteristics:

  •  As it is fixed on top of the display, it should not impact the quality of the display image.
  • The touchscreen panel’s active area should be equal to that of the video display.
  • Activation is not dependent on the size of stylus, conducting or non-conducting nature of stylus and touch of a gloved or non-gloved finger.
  • It is capable of providing positive tactile responses.
  • Construction should be flexible and capable of integration with other input devices and networks.
  • It is impervious to adverse environmental conditions of dust, grease, water or moisture, pressure, vibrations, chemicals, or oil vapours.

The technology within the touch panels
A variety of touchscreen technologies with different methods of operation and touch sensing are available in the market. The range starts from standard resistive touchscreen, which is still the popular choice for cost-sensitive applications. It has three different types, namely, 4-Wire resistive touch screens, 5-Wire resistive touch screens and 8-Wire resistive touch screens.

Besides, there are standard capacitive, projected capacitive, scanning infrared (IR) and surface acoustic wave (SAW) as multiple options for touchscreen panels. All of them are composite units that include a touchscreen overlay and an information-processing controller.

We also have some best advancements in touch panels; A D Metro’s ULTRA glass armoured resistive touchscreens are one of the most notable. It is the most durable and reliable resistive touch screen sensor available in the market. What makes ULTRA resistive an extraordinary choice for touchscreens is its patented durable glass surface that is scratch, abrasion and chemical resistant and allow usage over an extended range of operating environments. It offers easy integration with numerous applications and can be operated using a bare finger, stylus or gloved fingers. It also can offer two touch capability for pinch, zoom and rotate functionality with A D Metro’s patented 2-touch 5-wire controller.
