Precise controllers
Multi-touch capable PCAP touchscreens require very precise controllers that not only capture unlimited touch points, but also ignore unintentional touches in order to process only the desired touches.
Another important requirement is that the controller reliably shields induced interference radiation, which is more difficult, especially with larger screen diagonals.
A high noise reduction or a large S/N ratio is an additional, important requirement for the touch controller, especially with a high screen resolution. The aim is to minimize external interference and ensure the proper operation of the touchscreen.
Different input methods possible
The controller must reliably process various input methods using finger, glove or pen and at the same time offer a fast scan rate in order to deliver the smooth performance desired by the user.
Cost-effective and Reliable Single Chip IC Controller
Single-chip IC controllers are a cost-effective and space-saving variant for multi-touch capable PCAP touch screens. Alternatively, board controllers can also be used, which can be easily integrated into the respective system.
Interelectronix supplies the right controller for standard and special applications, tailored to
- the selected touchscreen technology,
- your individual requirements and
- the price expectations.
For our touchscreens we use controllers from Atmel. These high-quality and durable controllers complement our touch panels perfectly and contribute to a particularly long service life.
INTERFACES FOR CONTROLLER INTEGRATION
As standard, our controllers support the most common industry standards such as:
- USB
- RS232
- I2C
- SPI
