AI Technical Summary
In the existing technology, capacitive touch screens are easily affected by environmental interference, resulting in uneven charge distribution and false touch responses. Furthermore, the high cost or complexity of existing anti-interference measures limits their widespread application.
The touchscreen is refreshed promptly after a touch action ends, resetting it to its initial state. By monitoring touch release actions and performing refresh actions within a set time, including discharging and charging the capacitors, the refresh time is controlled in stages to optimize power consumption and anti-interference effects.
It effectively removes accumulated interference, ensures touchscreen response sensitivity, improves user experience, and eliminates the need for complex interference detection circuitry.
