Display module, fabrication method thereof and display device

A method for fabricating a display module having a touch area and a driving area on a side of the touch area, the method comprising:

• providing a display substrate comprising a plurality of light emitting units, each of the plurality of light emitting units comprising a first electrode, and the first electrodes of the plurality of light emitting units being coupled to form a first electrode layer;
• and
• forming a touch layer on the display substrate, the touch layer comprising a plurality of touch units in the touch area, and an orthographic projection of each of the plurality of touch units on the display substrate covers at least two light emitting units of the plurality of light emitting units, wherein each of the plurality of touch units comprises:
• a mesh conductive structure and a plurality of first transparent electrodes, the mesh conductive structure is coupled to a touch signal terminal in the driving area and comprises a plurality of conductive wires arranged crosswise to define a plurality of grids, an orthographic projection of each of the plurality of conductive wires on the display substrate is in a space between adjacent light emitting units, and each of the plurality of first transparent electrodes is located in the grid and electrically coupled to the conductive wire.
