The system includes a display device having a touch sensor with a matrix of row electrodes and column electrodes. Drive logic drives the row electrodes in a plurality of stylus sync sub-frames. In each, some row electrodes, referred to for that stylus sync sub-frame as sync-driven row electrodes, are driven by the drive logic with synchronization waveforms to synchronize the display device with an active stylus. For each stylus sync sub-frame, the sync-driven row electrodes are differentially driven by the drive logic, in the sense that a synchronization waveform used to drive one of the sync-driven row electrodes is different than a synchronization waveform used to drive another of the sync-driven row electrodes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active stylus differential synchronization","description":"A touch-sensing system is disclosed.
