Abstract
A pressure detection unit, a pressure detection method and a display panel are disclosed. The pressure detection unit includes a touch control pressure scanning electrode, a constant voltage electrode, a detection module and at least one touch control pressure induction electrode. A touch control pressure scanning signal is inputted into the touch control pressure scanning electrode; the constant voltage electrode is arranged opposite to the touch control pressure scanning electrode, and a constant voltage is inputted into the constant voltage electrode; an orthographic projection of the 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; the detection module is configured for determining a pressure applied on the pressure detection unit according to change of capacitance.
