1. A folding displayer support, comprising a support body, wherein the support body is provided with at least one first bending region extending in a first direction, at least one second bending region extending in a second direction, and at least one bidirectional bending region located at a position where the first bending region intersects with the second bending region, and an included angle is formed between the first direction and the second direction;
the first bending region is provided with a first mesh pattern, the second bending region is provided with a second mesh pattern, the bidirectional bending region is provided with a third mesh pattern, a proportion of holes of the first mesh pattern and a proportion of holes of the second mesh pattern are less than a proportion of holes of the third mesh pattern, and the proportion of holes is a percentage of an area occupied by holes in a unit area; and
a shape of one of the holes of the third mesh pattern is axisymmetric about a bending axis of the first bending region and a bending axis of the second bending region;
wherein the third mesh pattern comprises a first hollowed-out portion and a first solid mesh line portion, the first hollowed-out portion comprises a first hole array, the first hole array comprises a plurality of first holes distributed in an array, each of the first holes is a cross-shaped hole comprising a first strip-shaped hole and a second strip-shaped hole arranged in a cross shape, a length extension direction of the first strip-shaped hole is the first direction, and a length extension direction of the second strip-shaped hole is the second direction;
wherein the first hollowed-out portion further comprises a second hole array, the second hole array comprises a plurality of second holes distributed in an array, and each of the second holes is surrounded by the first solid mesh line portion in the middle of four adjacent first holes distributed in the array;
wherein
two opposite ends of the first strip-shaped hole are in a circular arc shape or an elliptical arc shape, and/or
two opposite ends of the second strip-shaped hole are in a circular arc shape or an elliptical arc shape; and
the first solid mesh line portion at a corner of a region where the first strip-shaped hole intersects with the second strip-shaped hole is a transition curve in a circular arc shape or an elliptical arc shape;
wherein the first solid mesh line portion at the corner of the region where the first strip-shaped hole intersects with the second strip-shaped hole comprises at least one quarter circular arc or quarter elliptical arc, a diameter of the quarter circular arc is greater than or equal to 0.2 mm, and a minor axis of the quarter elliptical arc is longer than or equal to 0.2 mm.
