Abstract
A display panel and a preparation method thereof, and a display device. The display panel includes a display main body, which includes a display area and an encapsulation area, and the display panel further has deformation detection elements, including: an electro-display module having 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. The piezoelectric module includes two or more piezoelectric units disposed at intervals on the surface of the deformable functional layer, and a voltage difference is applied between two adjacent piezoelectric units. An electro-display unit is connected in series between the two adjacent piezoelectric units. The display panel can detect in real time whether deformation occurs through the deformation detection means, thereby ensuring the encapsulation quality and display effect.
