4 Wire Resistive

The lowest cost solution, 4 wire resistive touchscreens are glove compatible. Suitable for use in devices such as portable instruments, consumer products and remote controls. A protective laminate can be added for extra protection from scratches. Available in a range of sizes from 5.7″ to 15″ with anti- glare, anti Newton top sheet.

5 Wire Resistive

Film/Glass construction offers a much higher touch life (35M actuations), and quick response time. Suitable for POS devices, gaming machines and ATM machines. The method of construction means this screen may still function even when top layer is damaged. Standard sizes range from 5.7″ to 24″.

8 Wire Resistive

This option offers the same benefits as 4-wire without the need for field calibration. Available in several constructions this screen is suitable for applications in harsh environments, for example factory control devices, industrial PC’s and instrumentation. Available in standard sizes from 7″ to 20.1″.

Glass Front 5 Wire Resistive Touchscreens 

This technology is suited to high use applications, in harsh environments. The touchscreen has a smooth, thin and very durable glass top sheet with a 7H pencil hardness for increased durability, scratch and wear resistance. These screens are not affected by dust, water, chemicals or light.  Used in military, kiosk, public interface devices or where a film construction would be unsuitable. Non conductive devices will actuate the screen. Standard sizes from 7.0″ to 17.1″.

Multi Touch Projected Capacitive Touchscreens (PCT) 
PCT Touchscreens are an all glass construction offering superior durability and optics. Support for multi touch gesturing, this touchscreen can be matched with standard controller boards (see below) or chip on flex options.The Glass on glass construction has > 9H surface hardness, and optionally a decorated lens cover can be added, with features such as anti glare, heat tempered and heat strengthened glasses being just some of the choices. Input is with gloved hand, conductive stylus or finger.

Available in a standard sizes from 4.3″ to 24″.
