Resistive Touch Screen Solutions
What We Offer
As pioneers in touch screen engineering and manufacturing, Touch International designs and manufactures 4-wire, 5-wire, 8-wire and multi-touch resistive touch screen products for a wide variety of industries including medical, aerospace, industrial and retail. For projects requiring low cost, pressure sensing touch screens with low power draw, Touch International’s resistive touch screens deliver unparalleled value and flexibility in construction, design and performance.
Whether your project requires enhanced optics, advanced functionality or multi-touch capabilities, our resistive touch screens can be manufactured to meet your exact specifications. Talk to a Touch International sales rep today about building a resistive touch solution for your interactive project.
With standard sizes ranging from 3.8” to 26”, Touch International’s resistive touch screens are available as off-the-shelf touch panels or as fully customized touch solutions and are form, fit or function replacements for 3M™ and Elo™ touch sensors. Allowing for versatile input methods, Touch International’s resistive products work with bare and gloved fingers and any other input device.
The resistive touch screen consists of a glass layer with a conductive coating on top and a polyester top sheet with a conductive coating on the bottom. The conductive surfaces are held apart by “spacer dots”, usually glass beads that are silk-screened onto the coated glass. On a 5-wire resistive design (the most commonly used kind of resistive screen in large format POS applications), a voltage is applied to the 4 corners of the glass layer. When a person presses on the top sheet, its conductive side comes in contact with the conductive side of the glass, effectively closing a circuit (this is called pressure sensing). The voltage at the point of contact is read from a wire connected to the top sheet.
