Customised Touch Solutions

GSR Technology Italy offers various touch screen options, touch monitors, touch computers and other customized tactile solutions for all market sectors, even the most demanding areas, such as the defence sector.

Our Touch technology solutions cover all the technologies currently available on the market, including resistive (4-wire, 5-wire), IR touch, Capacitive Touch, SAW, curved SAW, iSurface and Projected Infrared devices.

Touch panels are available in all standard formats, in addition to customer-defined sizes, and are equipped with RS 232 and USB interface controllers.

SAW

SAW touchscreen

SAW touch screens offer the advantages of durability, reliability and high light transmission.

Thanks to ease of customization and high cost efficiency, SAW touch screens represent the ideal solution for many applications, such as digital signage, transport, gaming, industrial and self-service devices.

GSR Technology Italy supplies vandal-proof, anti-glare, water-resistant, zero-frame and curved touch-screens.

SAW solutions offer > 90% light transmission, they are compatible with all Windows/Dos/Linux/Android operating systems and are available in all formats between 5.4" and 42".

iSurface

iSurface touchscreen

iSurface touchscreens use surface acoustic wave technology (SAW), and cover a wide range of applications, meeting the highest expectations of customers, both from an aesthetic point of view and for the tactile experience they offer.

All reflection strips, transducers and cables are positioned at the rear of the touch screen, resulting in a zero-frame screen structure.

The fully flat screen means the surface is perfect and easy to integrate into monitors and other devices, so much so that it is often confused with capacitive touch screens.

IR

Infrared touchscreen

This technology is based on the use of infrared emitters and receivers to create a grid capable of detecting the touch position

This technology functions without the need for actual contact with the screen surface. Available in formats ranging from 15" to 84".

The infrared touch screen operates on the principle that, whenever the infrared grid is interrupted, the transistors on the X and Y axes detect the absence of infrared light simultaneously, thereby registering the respective X and Y grid coordinates. The frame is equipped with an integrated printed circuit board, which includes a row of infrared LEDs and phototransistors that are hidden behind the frame of the touch screen.

For each of the infrared LEDs, there is a corresponding phototransistor positioned on the opposite side of the frame, thereby creating a grid of invisible infrared rays. The frame protects the electronic components from the operating environment, while permitting the passage of infrared rays. The infrared touch screen controller sends light pulses in sequence via the LEDs.

PCT

PCT touchscreen

The explosive expansion of the smartphone market has seen rapid growth in both the popularity and quality of capacitive touch screens.

Capacitive technologies detect the touch by measuring the capacitance of each addressable electrode. When a finger or conductive stylus is placed close enough to the electrode, it disturbs the electromagnetic field and alters the capacitance of the electrode.

This change in capacitance is measured by the electronics and then converted into X, Y positions that the system can use to identify the touch position. There are two main types of detection methods, self-capacitance and mutual capacitance.

This technology, which is widely used and appreciated in all market sectors, offers a precise and fast response to the touch, while the completely flat surface lends devices an elegant and refined appearance and excellent multi-touch performance; it is also suitable for use on large format displays.

Our highly skilled team is able to offer our customers any of the PCT touchscreen solutions currently available on the market, providing support during both the development stage and your day-to-day production operations.

Resistive

Resistive touchscreen

An analogue resistive touchscreen is a sensor consisting of two opposing layers, each coated with a transparent resistive material known as indium tin oxide (ITO).

The typical sheet resistance value of ITO is between 100 and 500 ohms per square. The layers are separated by a pattern of very small transparent insulating points. The silver ink bars (c. 50mW/sq) create an electrical connection between the surface of the ITO and the external edges, extending the desired axis of the specified level.

Traces of silver ink (c. 50mW/sq) connect the bus bars to an electromechanical connector used to interface with the sensor. When touched, the conductive coating creates an electrical contact with the coating on the glass and a touch is registered by the controller.

Resistive touch screens are very competitively priced and provide consistent, long-lasting performance in environments where equipment must be designed to be resistant to contaminants and liquids; in addition, they may also be used with gloves.

The downside of this technology is its low optical transparency, equivalent to about 75%.

Suitable for use with small and medium sized displays.
