Resistive Touch Screens
What’s with all the wires?
There are several “flavors” of resistive touch screens: 4-wire, 5-wire and 8-wire. More wires does not always mean that it’s better. And actually, they are not really wires, but an electrical trace. Here’s how it works.
Consisting of top and bottom transparent sheets facing each other with a gap between them, as the top sheet gets pressed it contacts the bottom sheet. From there, the electricity is conducted at the contact point and the location of the conducted point is detected. Different constructions are available such as glass, glass-plastic and plastic-plastic and the selection depends on the functionality and type of your application.
Where are Resistive Touch Screens used?
Resistive touch screens are used in a variety of applications ranging from medical devices and consumer products to military and industrial applications. When selecting the touch screen technology for your device, it’s important to keep in mind the power requirement of your device, environmental contingencies, cost and reliability performance of the device.
eN-Touch specializes in 4-wire resistive touch screens and 4-wire touch panels, which are typically made of glass bottom and film top.
Our 5-wire resistive touch screen is as durable and reliable as it gets. eN-Touch specializes in 5-wire touch screen & touch panels.
Our 8-wire resistive touch screen is a super charged 4-wire resistive touch screen.
