QT60040-S

The QT60040-S is a three-in-one touch screen controller with capacitive sensing that offers excellent performance, durability and cost savings. Combining a 4-bit LED driver, a 16-bit MCU, and a tailored capacitive sensor, the QT60040-S provides an integrated solution for two-dimensional (2D) finger tracking in all kinds of touch sensors, such as touch panels and touch probes. This system comes in several integrated and configurable packages, making it one of the most competitive solutions in the industry.

Application Fields:The QT60040-S is a great choice for embedded applications that require a responsive and reliable touch navigation experience. With its advanced algorithm, the controller can detect finger movements with excellent accuracy and speed, offering a smooth and intuitive navigation experience without any delay. The controller’s special scan patterns ensure the highest accuracy and most reliable operation and make it suitable for interactive television applications, remote control devices, miniature gaming consoles, cell phone input devices, and more.

Working Principle:The operating principle of the QT60040-S is based on the digitalized drive signals that are generated every time a finger touches the panel, allowing for more precise digital sampling and better calibration. The capacitive sensing technology behind the controller makes it capable of detecting and tracking finger movement with absolute accuracy. To create the digital scan signals, the controller transmits high-frequency signals to the panel and then measures the capture time of the signals. This time-of-flight determination allows the controller to calculate the exact finger location and track its movement.

In addition to the finger tracking, the QT60040-S features advanced noise reduction technology for improving the overall touch experience. This technology filters out noise and other artifacts that might be generated during the finger tracking process and results in a more accurate and enjoyable navigation performance. Other features of the controller include an integrated temperature monitoring system for improved thermal performance, self-calibration for ease of use, and low power consumption for extended battery life.

The QT60040-S is an ideal solution for anyone looking for an advanced two-dimensional capacitive finger tracking system at a competitive price. Combining the cost savings of an all-in-one solution with advanced sensing and noise reduction capabilities, this controller offers the best of both worlds and will provide users with a fast, accurate and reliable touch navigation experience.
