Claim 0:
1. A touch substrate, comprising:
a base substrate, a touch driving electrode, a touch sensing electrode and a grounding electrode and a floating electrode;
wherein the touch driving electrode, the touch sensing electrode and the grounding electrode are located on the base substrate and insulated from one another; wherein an orthographic projection of the grounding electrode on the base substrate and orthographic projections of the touch driving electrode and the touch sensing electrode on the base substrate have a non-overlapping region with each other;
the touch driving electrode comprises a plurality of driving electrode blocks arranged in array, and the touch sensing electrode comprises a plurality of sensing electrode blocks arranged in array; and the touch driving electrode further comprises a plurality of first bridging sub electrodes configured to electrically connect the adjacent driving electrode blocks and arranged in a layer different from a layer in which the plurality of driving electrode blocks is arranged, or the touch sensing electrode further comprises a plurality of second bridging sub electrodes configured to electrically connect the adjacent sensing electrode blocks and arranged in a layer different from a layer in which the plurality of sensing electrode blocks;
the floating electrode is located between the driving electrode blocks and the grounding electrode, and/or the floating electrode is located between the sensing electrode blocks and the grounding electrode; and
an orthographic projection of the floating electrode on the base substrate surrounds an orthographic projection of the grounding electrode on the base substrate; and the orthographic projections of the touch driving electrode and the touch sensing electrode on the base substrate are not located between the orthographic projection of the floating electrode on the base substrate and the orthographic projection of the grounding electrode on the base substrate.
