A display module and a fabrication method thereof, and a display device, and relates to the field of display technologies, to synchronously implement a display function and a surface tactile reproduction function. The display module includes: a base substrate, a plurality of piezoelectric structures positioned on a first side of the base substrate, and at least one isolation portion positioned on the first side of the base substrate and configured to separate any two adjacent piezoelectric structures. A pixel hole is arranged in at least one of three positions, i.e., a position of the piezoelectric structure, a position of the isolation portion, and a position between the piezoelectric structure and the isolation portion. The display module also includes a plurality of pixel structures, and each of the plurality of pixel structures is positioned in one of the pixel holes.
