Zusammenfassung:The invention discloses a single-layer capacitive touch unit, including a sensing electrode, connected to a control unit through a sensing electrode lead; and a plurality of scan electrodes, disposed at two sides of the sensing electrode; the scan electrode being connected to the control unit through a scan electrode lead, and the scan electrodes and the sensing electrode being coplanar; wherein one end of scan electrode lead connected to a second end of scan electrode and extending to near a next scan electrode to form extending lead; and the other end of scan electrode lead connected to the control unit. The invention also provides a capacitive touch screen with the capacitive touch unit. The invention can reduce the effect of noise signal on the touch signal and increase SNR of the touch signal.
