Abstract: A display panel buffering structure, a display screen module and a preparing method therefor, and a terminal device are provided. The display panel buffering structure is arranged on the side face, facing away from a light-emitting side, of a display panel, and comprises: a buffering film provided with a hollow structure for accommodating an exciter; and a first light shielding film attached to a first side face, facing the display panel, of the buffering film. An orthographic projection of the first light shielding film on a plane where the first side face is located covers an orthographic projection of the hollow structure on the plane where the first side face is located, and a portion, opposite to the hollow structure, of the first light shielding film is fixed with the exciter.
