Organic light emitting diode display module, manufacturing method thereof and electronic device

A method for manufacturing an organic light emitting diode display module, wherein the method comprises following steps:

• providing a substrate with a lead and a power cable formed on the substrate;
• forming a flat layer on the substrate, the flat layer defining a first through hole and a second through hole, and a part of the lead corresponding to a position of the first through hole;
• forming an anode layer on the flat layer and within the second through hole;
• forming a pixel definition layer on the flat layer and the anode layer, the pixel definition layer defining a third through hole and a fourth through hole, and a part of the anode layer corresponding to a position of the third through hole, the fourth through hole interconnecting with the first through hole;
• forming a light-emitting layer within the third through hole and on the anode layer;
• forming a cathode layer on the pixel definition layer, the light-emitting layer, and the lead;
• the cathode layer comprising a plurality of wire blocks arranged at intervals;
• and each wire blocks comprising a bent conductive wire;
• one end of each conductive wire is coupled to the lead, and the other end of each conductive wire is coupled to the power cable.
