The control unit outputs driving signals to a plurality of touch driving electrodes and receives sensing signals from a plurality of touch sensing electrodes so as to detect touch or proximity of at least one external object based on the capacitive coupling between the driving and sensing electrodes. The display includes a liquid crystal layer, a pixel electrode and a common electrode, wherein the liquid crystal layer is driven by the pixel electrode and the common electrode. The common electrode includes the touch driving electrodes, and the common electrode except the touch driving electrodes are electrically coupled to a DC potential to form a shielded region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch display and method for driving a plurality of touch driving electrodes of touch display","description":"A touch display provided by the present invention includes a control unit and a display.
