SENSOR DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18135625 titled 'SENSOR DEVICE
Simplified Explanation
The patent application describes a sensor device that includes first sensors, second sensors that form a capacitance with the first sensors, and a sensor driver that transmits driving signals to the first sensors and receives sensing signals from the second sensors.
- The sensor driver sequentially transmits driving signals to the first sensors and transmits an offset signal, which is identical in frequency to and different in phase from the driving signals, to at least one selected first sensor that does not receive the driving signals.
- The sensor driver sets the slew rate and voltage level of the offset signal to values different from the corresponding values of the driving signal.
- Potential Applications:**
- Touchscreen devices
- Proximity sensors
- Gesture recognition systems
- Problems Solved:**
- Minimizing interference between driving and sensing signals
- Improving accuracy of sensor readings
- Benefits:**
- Enhanced sensitivity and accuracy of sensor measurements
- Reduced noise and interference in sensor data
- Improved performance in touch and gesture recognition applications
Original Abstract Submitted
A sensor device includes: first sensors; second sensors which forms a capacitance with the first sensors; and a sensor driver which transmits driving signals to the first sensors through first sensor lines, and receives sensing signals from the second sensors through second sensor lines. The sensor driver sequentially transmits the driving signals to the first sensors, and transmits, during each period of transmitting the driving signals, an offset signal, which is identical in frequency to and different in phase from the driving signals, to at least one selected from first sensors which does not receive the driving signals among the first sensor. The sensor driver sets at least one selected from a slew rate and a voltage level of the offset signal to a value different from a corresponding value of a corresponding driving signal.
