Display panel, preparation method for display panel, and display device

A display panel, comprising a display main body, the display main body comprising a display area and an encapsulation area, wherein the display panel further comprises a deformation detection means, the deformation detection means comprises:

• an electro-display module comprising one or more electro-display units;
• and
• a piezoelectric module positioned on a surface of at least one deformable functional layer in the display main body and positioned in the encapsulation area;
• wherein the piezoelectric module comprises at least one first piezoelectric unit and at least one second piezoelectric unit, and a voltage difference is applied between the first piezoelectric unit and the second piezoelectric unit;
• and wherein the first piezoelectric unit and the second piezoelectric unit disposed on the surface of a same deformable functional layer are alternated and spaced apart from each other, two adjacent piezoelectric units are connected in series by an electro-display unit therebetween, and a spacing between the two adjacent piezoelectric units is such that when the deformable functional layer is deformed, the two adjacent piezoelectric units contact each other to generate a pressure signal which is converted into an electrical signal, and the electrical signal excites the electro-display unit that is connected in series between the first piezoelectric unit and the second piezoelectric unit to display.
