Touch International is an expert in touch screen technology, starting with resistive technology and advancing in projected-capacitive. As a full-service touch screen display solutions center, we design and manufacture custom touch screens and components. We specialize in display enhancements for touch screens and LCDs and often use enhancements to conquer environmental challenges. Over 20 years of experience and quality engineering ensures that your final product meets or exceeds the requirements for your application.

The most commonly used type of resistive technology is a 5-wire design, where a voltage is applied to the 4 corners of the glass layer. Pressure sensing occurs when a person presses on the top sheet, and the conductive sides from both layers come in contact with one another. The point of contact closes the circuit, and the voltage is read from a wire connected to the top sheet.

4-wire, 5-wire, and 8-wire resistive touchscreen products provide low-cost touch screen solutions. The reliable pressure-sensing technology has a beneficial, low power draw. Our resistive touchscreens deliver unparalleled value and flexibility in construction, design, and performance.

Our line of open frame touch monitors is a turnkey solution for quick prototyping.  There is no NRE with standard configurations. Customize as much or as little as you need with low MOQs. Volume pricing and Terms are available for approved customers.

Touch International designs and manufactures standard and custom MulTI-Touch and Digital Switch projected capacitive (PCAP) touchscreen products. Our PCAP products deliver outstanding optics, quick response times, and unmatched durability.

Touch screentechnology types

Resistive touch screens consist of two layers of conductive surfaces. First, the bottom layer is a sheet of glass with a conductive coating on top. Second, the top layer is a polyester top sheet with a conductive coating on the bottom.  The conductive surfaces face each other and are held apart by “spacer dots,” usually glass beads that are silk-screened onto the coated glass.

Additionally, our staff of extensive touchscreen experts will streamline your touch project from concept design to implementation. For more in-depth information, please read our white paper on Filters and Custom Touchscreen Enhancements.

5 uses oftouch screen

Mutual capacitance is now the more common projected capacitive approach and makes use of the fact that most conductive objects are able to hold a charge if they are very close together. If another conductive object, in this case, a finger, bridges the gap, the charge field is interrupted and detected by the microcontroller.
