Description

Display module and display device Technical Field The application relates to the technical field of display, in particular to a display module and a display device. Background At present, except for improving the performance of a mobile phone, the reworkability of a mobile phone screen after the whole mobile phone is assembled is required to be improved, most terminals are required to have the damage rate of not more than 20% when the mobile phone screen is disassembled, and some terminals are required to have the damage rate of not more than 5%, so that a large number of terminals are disassembled for verification in a trial production stage. At present, delamination of the machine is mainly concentrated between copper foil of the heat dissipation film and foam, between the heat dissipation film and the display panel, and the like. The whole machine end can use the middle frame glue to bond and fix the module and the whole machine at the edge of the copper foil of the heat dissipation film, when the machine is disassembled, the middle frame glue is heated to reduce the heated viscosity, the module is disassembled at the moment, but the edge of the copper foil is also bonded on the display panel, after being heated, the viscosity of the glue of the copper foil and the heat dissipation film is reduced, and when the viscosity of the glue of the two layers after being heated is not higher than that of the middle frame glue, the two layers of the layering interface can appear when the machine is disassembled, so that the module is damaged and scrapped. Disclosure of Invention The application provides a display module and a display device, which aim to solve the problem of delamination of a disassembling machine, reduce the damage rate of the disassembling machine and enable the display module to be normally reused.
