CONCURRENT INPUT SENSING AND DISPLAY UPDATING |
摘要 |
<p>Embodiments of the present invention generally provide a processing system for a display device integrated with a capacitive sensing device. The processing system includes a driver module having driver circuitry and coupled to a sub-pixel with a first source line and a first common electrode. The driver module is configured to simultaneously update the sub-pixel by driving the first source line with a first voltage, and drive the first common electrode for capacitive sensing by modulating the first common electrode between a second voltage and a third voltage. The processing system further includes a receiver module coupled to a plurality of receiver electrodes. The receiver module is configured to receive resulting signals from the receiver electrodes while the first common electrode is modulated between the second voltage and the third voltage. The processing system further includes a determination module configured to determine positional information based on the resulting signals.</p> |
