1. A display module, comprising:
a display panel, comprising a to-be-thinned substrate and a touch substrate opposite to each other, wherein a surface of the touch substrate facing away from the to-be-thinned substrate is a to-be-protected face, and the to-be-thinned substrate is divided into a to-be-thinned region and a non-thinned region in a direction pointing from the to-be-thinned substrate to the touch substrate;
a protective film, located on the to-be-protected face of the display panel, wherein the protective film covers a part of the to-be-protected face;
a first anti-acid film, located on a surface of one side of the protective film facing away from the to-be-protected face, wherein an orthographic projection of the first anti-acid film on the to-be-protected face falls in the to-be-protected face, and an orthographic projection of the protective film on the first anti-acid film falls in the first anti-acid film;
a second anti-acid film, located on a surface of one side of the first anti-acid film facing away from the to-be-protected face, wherein an orthographic projection of the second anti-acid film on the to-be-protected face falls in the to-be-protected face, and an orthographic projection of the first anti-acid film on the second anti-acid film falls in the second anti-acid film; and
a sealant, covering a region of the to-be-protected face not covered by the protective film, a side face of the touch substrate and a side face of the non-thinned region.
