1. A display module, comprising a display film layer, a heat dissipation film layer, a support plate and an elastic thermal conductive sheet;
wherein the display film layer and the heat dissipation film layer comprise a flat area and bending areas located on both sides of the flat area, and an angle exists between a tangent of a curved surface formed by each of the bending areas and a plane where the flat area is located;
the display film layer is stacked on a first surface of the heat dissipation film layer;
the support plate is connected to a position where the flat area of a second surface of the heat dissipation film layer is located, and the elastic thermal conductive sheet is connected to a position where the bending areas of the second surface of the heat dissipation film layer are located;
wherein the first surface and the second surface are two opposite surfaces of the heat dissipation film layer.
