[0037] Foldable display modules in related technologies, such as Figure 1 As shown, it includes a stacked display panel 100 and a touch panel 200. Since the panels are both flexible and bendable, in order to meet the needs of the display panel after bending, a whole layer of supporting flat layer 300 is set on the non-display panel of the display panel 100. The supporting flat layer 300 is also flexible. In order to achieve foldability, the heat dissipation layer of the display module is generally divided into two independent layers (a first heat dissipation layer 400 and a second heat dissipation layer 500), and the first heat dissipation layer 400 and the second heat dissipation layer 500 are both grounded. However, since the material of the supporting flat layer 300 is also a metal material and the supporting flat layer 300 is not grounded, during the bending process of the display module, the supporting flat layer 300 will interfere with the touch signal in the touch panel and affect the touch performance.

[0038] In view of this, an embodiment of the present invention provides a display module, such as Figure 2-Figure 4 , Figure 6-Figure 8 As shown, including:

[0039] The display panel 100 is a flexible display panel. The display panel 100 includes a first non-bending area A1, a bending area B, and a second non-bending area A2. The first non-bending area A1 is connected to the second non-bending area A2 through the bending area B. The bending area B is used for bending or unfolding the display module. The bending area B refers to the area that is bent and stretched when the display module is bent. The first non-bending area A1 and the second non-bending area A2 refer to the areas that are not bent when the display module is bent. The bending area and the non-bending area can be divided according to different display module models and different application scenarios. The embodiment of the present invention Figure 2 The specific division of the bending area and the non-bending area is only one implementation method, and no specific limitation is made thereto; in addition, the surface of the display panel 100 for displaying an image is referred to as a display surface 100a, and the surface opposite to the display surface 100a is referred to as a non-display surface 100b;

[0040] A support and flattening layer 300, which is located on a side away from the display surface 100a of the display panel 100, and is used to support and flatten the display panel 100; specifically, the overall hardness of the bendable flexible display panel is insufficient, and the support and flattening layer 300 can be used to support the flexible display panel, and the support and flattening layer 300 provides rigid support for the flexible display panel in the first non-bending area A1 and the second non-bending area A2, and improves the problem of flexible deformation of the flexible display panel in the full-lamination process, thereby improving the problem of uneven surface of the flexible display panel after full-lamination, and further improving the surface flatness of the flexible display panel, and the material of the support and flattening layer 300 is metal;

[0041] A first heat dissipation layer 400 , which is located in the first non-bending area A1 , and is located on a side of the supporting and planarizing layer 300 away from the display panel 100 ;

[0045] At least one of the first heat dissipation layer 400 and the second heat dissipation layer 500 is electrically connected to the support and planarization layer 300.
