CAPACITIVE TOUCH SCREEN HAVING DYNAMIC CAPACITANCE CONTROL AND IMPROVED TOUCH-SENSING |
摘要 |
<p>Methods and apparatus for improving the sensing performance of a capacitive touch screen sensing device. The electrical potential of conductive structures proximate capacitive touch pads of the sensing device is altered to compensate for the effect of parasitic capacitance, based on external conditions such as water on the touch screen or an intervening user worn glove. The compensation for parasitic capacitance improves the signal to noise ratio and therefore the sensing performance of the device.</p> |
