Overview

Capacitive touch solutions. We're producing ITO on glass, also we can make every pattern of ITO. (buttons, sliders, wheels and diamonds). Advanced Touchscreen Technology B.V. (ATT) develops and produces in a socially and environmentally responsible manner touchscreens using sustainable materials and technologies. Innovation, exibility and customized products are the strenght of ATT. Unique technology for low cost capacitive touchscreens and patterned ITO ATT’s technology is based on combining a unique deposition technique with innovative manipulation of the chemistry and physics of the processes. The main advantages are that low temperature and no vacuum are used in an inline process. ATT developed a capacitive touchscreen with a high clarity and a long-lasting lifetime. It is made of glass with an ITO coating that is scratch resistant, due to its chemical structure which makes it extremely durable, not affected by external factors. A capacitive touchscreen operates by detecting a change in a known electrical current that occurs when the screen is touched. An AC signal voltage is applied to the front conductive surface of the sensor through four corner wires. All four corners are driven with the same voltage, phase and frequency. Where the glass is touched, a small amount of electrical energy is coupled capacitively from the sensor to the user, causing a small but measurable amount of current to flow through each corner. The system identifies a touch comparing a known ‘baseline’ with the change in current when the screen is touched. A capacitive touchscreen is ideal for frequent use. It can also be gasket sealed and it is water resistant. The A group ATT belongs to a group of companies that jointly cover the whole range from touchscreen development to market implementation.
