In one embodiment, a plurality of driving voltages is generated. The driving voltages include a common voltage, and a first and a second gate-drive reference voltages for configuring a thin film transistor (TFT) in the panel to switch on and off, respectively. When the panel is operated in a sensing mode, the common voltage that is generated includes a pulse-train waveform. Furthermore, each of the first and the second gate-drive reference voltages is substantially time-synchronized to and includes the pulse-train waveform of the common voltage during the sensing mode. In one option, the driving voltages further include a sensing-mode source-drive voltage acting as a source-drive signal for the TFT during the sensing mode. The sensing-mode source-drive voltage is substantially time-synchronized to and includes the pulse-train waveform of the common voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for enhancing touch sensing in a display panel","description":"Driving a touch-sensing-enabled active matrix LCD display panel for enhancing touch sensing by reducing parasitic capacitances is considered.
