1. A supporting backplane, disposed on a side of a flexible display panel, the supporting backplane at least comprising a main bending area, and a bending axis corresponding to the main bending area extending in a first direction; and the main bending area being provided with a plurality of first hollow holes, and the plurality of first hollow holes being arranged in an array in the first direction and in a second direction orthogonal to the first direction; and each of the first hollow holes having a first middle hole area and first arc-shaped hole areas located at two sides of the first middle hole area in the first direction;
wherein, along a direction from positions where the first middle hole area is connected to the first arc-shaped hole areas to a central position of the first middle hole area, a size of the first middle hole area gradually decreases in the second direction,
wherein a diameter of the first arc-shaped hole area is 0.1 mm to 0.4 mm;
a size of the first middle hole area in the first direction is 2 mm to 7 mm, a maximum size of the first middle hole area in the second direction is identical with the diameter of the first arc-shaped hole area, a minimum size of the first middle hole area in the second direction is 0.05 mm to 0.35 mm, and a curvature radius of the arc-shaped contour line of the first middle hole area is 10 mm to 50 mm.
