Abstract
A capacitive sensing device, a touch screen, and an electronic equipment are disclosed. The capacitive sensing device includes a first conductive line extended along a first direction and a second conductive line extended along a second direction. The first conductive line is insulated from the second conductive line and the first conductive line and the second conductive line are disposed in an overlapping manner. The first conductive line includes first sensing electrodes and a first connecting bridge. The second conductive line includes second sensing electrodes and a second connecting bridge. The second connecting bridges bypass the first connecting bridges to avoid a short circuit or an open circuit in overlapping portions because of an electrostatic discharge. The first and second connecting bridges are smooth conductive lines. The present invention effectively reduces a probability of occurrence of electrostatic discharge, and is also simple and the transmittance is also higher.
