1. A touch substrate, comprising a plurality of capacitive touch driving electrodes extending in a row direction and a plurality of capacitive touch sensing electrodes extending in a column direction, the capacitive touch driving electrodes and the capacitive touch sensing electrodes being insulated and spaced from each other, wherein the touch substrate further comprises a plurality of first pressure sensitive electrodes extending in the row direction and a plurality of second pressure sensitive electrodes extending in the column direction, the first pressure sensitive electrodes being insulated and spaced from the capacitive touch sensing electrodes and the capacitive touch driving electrodes, the second pressure sensitive electrodes being insulated and spaced from the capacitive touch sensing electrodes and the capacitive touch driving electrodes, and when the touch substrate is touched, a voltage corresponding to a pressure at a touch position is generated between the first pressure sensitive electrode and the second pressure sensitive electrode corresponding to the touch position,wherein at least one capacitive touch driving electrode is provided between any two adjacent first pressure sensitive electrodes, and at least one capacitive touch sensing electrode is provided between any two adjacent second pressure sensitive electrodes,wherein each of the capacitive touch sensing electrodes comprises a plurality of capacitive touch sensing electrode patches connected with each other successively, and each of the capacitive touch driving electrodes comprises a plurality of capacitive touch driving electrode patches connected with each other successively, andtwo capacitive touch driving electrode patches of the same capacitive touch driving electrode on both sides of the same second pressure sensitive electrode are bridged by a first bridging element, and the first bridging element is insulated and spaced from the second pressure sensitive electrode;

  • and two capacitive touch sensing electrode patches of the same capacitive touch sensing electrode on both sides of the same first pressure sensitive electrode are bridged by a second bridging element, and the second bridging element is insulated and spaced from the first pressure sensitive electrode.
