SENSING DURING NON-DISPLAY UPDATE TIME TO AVOID INTERFERENCE
First Claim
1. A method of capacitive sensing using an integrated capacitive sensor device and display device, said method comprising:
- transmitting a transmitter signal with a combination electrode of said integrated capacitive sensor device and display device, said combination electrode configured for both capacitive sensing and display updating, wherein said transmitter signal transitions at least twice during a non-display update time period associated with row update of said display device;
updating a display of said display device during an update time period; and
receiving a resulting signal with a receiver electrode of said integrated capacitive sensor device and display device during said non-display update time period, said resulting signal corresponds to said transmitter signal.

Abstract
In a method of capacitive sensing using an integrated capacitive sensor device and display device, a transmitter signal is transmitted with a combination electrode of the integrated capacitive sensor device and display device. The combination electrode is configured for both capacitive sensing and display updating. The transmitter signal transitions at least twice during a non-display update time period associated with row update of the display device. A display of the display device is updated during an update time period. A resulting signal is received with a receiver electrode of the integrated capacitive sensor device and display device during the non-display update time period. The resulting signal corresponds to the transmitter signal.
