Pressure Detection Unit, Pressure Detection Method and Display Panel

A pressure detection unit, comprising:

• a touch control pressure scanning electrode, which is configured for inputting a touch control pressure scanning signal;
• a constant voltage electrode, which is arranged opposite to the touch control pressure scanning electrode, wherein the constant voltage electrode is configured for inputting a constant voltage;
• at least one touch control pressure induction electrode, wherein an orthographic projection of the at least one touch control pressure induction electrode in a plane where the touch control pressure scanning electrode locates does not overlap with the touch control pressure scanning electrode;
• and
• a detection module, which is electrically connected to the touch control pressure scanning electrode and the at least one touch control pressure induction electrode, wherein the detection module is configured for determining a pressure applied on the pressure detection unit according to change of directly opposite capacitance generated between the touch control pressure scanning electrode and the constant voltage electrode and change of coupling capacitance generated between the touch control pressure scanning electrode and the at least one touch control pressure induction electrode upon a touch control operation occurring.
