Abstract
The invention discloses an in-cell inductive touch-control display substrate, an inductive touch-control screen and a touch-control display device. The in-cell inductive touch-control display substrate includes: a first electrode layer; a second electrode layer insulated from the first electrode layer to form an electric field; first electromagnetic inductive coils extending in the row direction and forming loops and second electromagnetic inductive coils extending in the column direction and forming loops, disposed in the same layer as the first electrode layer. The first electromagnetic inductive coils or the second electromagnetic inductive coils are broken into a plurality of electromagnetic inductive segments at the crossings of the first and second electromagnetic inductive coils. Bridge wires disposed in the same layer as the second electrode layer electrically connect the electromagnetic inductive segments of the first electromagnetic inductive coils or the second electromagnetic inductive coils.
