Systems and Methods for Capacitive Touch Detection |
| 摘要 |
System and methods are provided for touch detection. The system includes: a sensing capacitive network configured to generate a touch-sensing signal based at least in part on a touch panel capacitance; an internal capacitive network configured to generate an input signal based at least in part on a predetermined internal capacitance; a comparative network configured to compare the touch-sensing signal with a reference signal to generate a first comparison result and compare the input signal with the reference signal to generate a second comparison result; and a signal processing component configured to generate a detection result to indicate ether a touch event occurs on the touch panel based at least in part on the first comparison result and the second comparison result. |

1. A system for touch detection, he system comprising:
a sensing capacitive network configured to generate a touch-sensing signal based at least in part on a touch panel capacitance; an internal capacitive network configured to generate an input signal based at least n part on a predetermined internal capacitance; a comparative network configured to compare the touch-sensing signal with a reference signal to generate a first comparison result and compare the input signal with the reference signal to generate a second comparison result; and a signal processing component configured to generate a detection result, to indicate whether a touch event occurs on the touch panel based at least in part on the first comparison result and the second comparison result. |
