A support layer is located between the first panel layer and the second panel layer. The first panel layer and the second panel layer are connected by a bent region, and a thickness of the support layer close to the bent region is greater than a thickness of a first region of the support layer. A projection of the first region of the support layer on the first panel layer overlaps with a projection of a display driver chip on the first panel layer. After being stacked, the thickness of the screen module may be reduced to meet the user's requirement for a small thickness of an electronic device. ## Claims ### Claim 1 A screen module, comprising: a single display panel bent to form a first panel layer and a second panel layer, wherein the first panel layer is spaced apart from the second panel layer, and wherein the first panel layer and the second panel layer are connected by a bent region;
