ZYTOUCH touch sensor - Zytronic - #1

[OUCH®

The ZYTOUCH touch sensor is the most robust touch sensor based on Zytronic's embedded Projected Capacitive Technology (PCT™).

By utilising Zytronic's traditional lamination expertise, ZYTOUCH touch sensors are designed to provide the highest levels of transmission, excellent readability and unsurpassed protection against a wide range of physical threats in the touch market today. The touch sensors are accurate, highly dependable and have a rapid response time.

ZYTOUCH offers the designer of touch displays some unique competitive advantages, including:

• Unsurpassed impact, vandal and scratch resistance

• Ideal for public use and external applications

• 10msresponsetime

• No drift, no recalibration required

• Works with gloved and ungloved finger

• Unaffected by moisture and rain

• Increased reliability and life expectancy

• Ability to create sealed designs that comply with NEMA 4, 12 and IP65 standards or higher Output protocols compatibility for a variety of operating systems

• Numerous customisable options, including screen printed borders and logos, anti reflective treatments, thermal or chemical glass strengthening, integrated optical filters, etc.

Operation

The electronic controls effectively divide the screen into pixel sized sensing cells, using an array of embedded microfine single track electrodes which are nearly invisible on a powered display. These electrodes are connected to a controller board, and an oscillation freguency is established for each. Touching the glass causes a change in the freguency of the electrodes around that particular point, the position of which is accurately calculated and identified by the controller. Unlike other capacitive systems where the operator touches the actual conducting surface of the sensing panel, the active component of the PCT sensing element is embedded within the body of the laminate construction, ensuring long product life and stability. The front glass surface acts as a dielectric and enhances the capacitance of the touch sensor.

ZYTOUCH sensors can be supplied with a number of options including front surface anti-glare treatments, rear surface anti-reflection coatings, thermal or chemical glass strengthening and privacy or contrast enhancement filters.

The driver software allows the touch sensor to interface with the host computer's operating system by emulating the behaviour of a computer 'mouse' and translates taps on the touch sensor surface into mouse clicks.

Applications

ZYTOUCH touch sensors are proven to meet today's demanding reguirements for public access human machine interfaces, such as ATM's, ticket machines, medical displays, industrial displays, pay-at-the-pump gas machines, and interactive kiosk systems. The touch sensor is uniguely durable and dependable, the construction protecting the sensing elements against damage caused by moisture, heat and even vandalism.
