Abstract

The invention provides a display module and a display device. The display module comprises a display panel and a supporting assembly. The display panel comprises a display part, a bending part and a binding part; one side of the supporting assembly is attached to the display part, the other side of the supporting assembly is attached to the binding part, and the supporting assembly comprises a buffer layer, a composite film layer and a reinforcing layer; the composite film layer comprises a heat dissipation layer and a reinforcing layer arranged on the same layer as the heat dissipation layer, the hardness of the reinforcing layer is larger than that of the heat dissipation layer, and the orthographic projection of the reinforcing layer on the display panel coincides with the orthographic projection of the reinforcing layer on the display panel. According to the display panel, the reinforcing layer and the heat dissipation layer are arranged on the same layer, the hardness of the reinforcing layer is larger than that of the heat dissipation layer, the orthographic projection of the reinforcing layer on the display panel coincides with the orthographic projection of the reinforcing layer on the display panel, the reinforcing layer can provide better supporting force in the bending process, pressing deformation between the reinforcing layer and the heat dissipation layer is avoided, on the premise that the thickness is not increased, the problem of marks caused in the bending process is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module and a display device. Background technique [0002] The current OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display panel usually adopts Pad Bending (binding area bending) technology to achieve the effect of narrow frame, that is, firstly, yellow PI (polyimide) is coated on the glass substrate as Flexible substrate, and then TFT (Thin Film Transistor, thin film transistor) devices are fabricated on the flexible substrate, and then the whole flexible film layer is peeled off from the glass substrate after the module manufacturing process is completed, and then PadBending is performed to bind the The metal traces in the area are bent to the back of the display panel. Usually, the outermost side of the back of the display panel is the SCF (Super Clean Foam) component, which is a laminated structure of foam and copper. Because the material of ...
