The most common application of capacitive touchscreens is in mobile devices. They allow intuitive operation and direct interaction with applications and content, which has become the standard for personal electronics.
More and more laptops and all-in-one personal computers are being equipped with touchscreens. This provides users with a flexible interface that complements traditional mouse and keyboard operation with direct screen interaction.
Touchscreens in ATMs provide a robust and user-friendly interface for conducting financial transactions. The technology simplifies navigation through menus for a wide audience.
In vehicles, touch screens are used for satellite navigation systems (satnavs). They allow for easy and quick entry of destinations and operation of route options, adding to ease of use.
The technology is based on conductive properties. The screen has a transparent conductive layer of indium tin oxide and the user's finger acts as a second conductor, which is essential for interaction.
A controller maintains a uniform electrostatic field over the screen surface. When a conductive object, such as a finger, approaches the screen, this field is locally disrupted, providing the basis for detection.
Touch causes a measurable change in the local capacitance between the finger and the screen's electrode grid. The controller detects this change in electrical charge to register the touch.
The screen contains a grid of electrodes. By measuring the capacitance change at specific points on this grid, the controller can determine the exact X and Y coordinates of the touch for precise input.
At Dytos, we understand that each industry has specific requirements for touch solutions. That's why we offer a wide range of products and services designed to meet these diverse needs.
