CURVATURE ADJUSTMENT DEVICE OF CURVED DISPLAY SCREEN, CURVATURE ADJUSTMENT METHOD FOR CURVED DISPLAY SCREEN, AND CURVED DISPLAY DEVICE

摘要

A curvature adjustment device of a curved display screen (30), a curvature adjustment method for a curved display screen (30) and a curved display device. The curvature adjustment device of the curved display screen (30) comprises: a supporting back plate (10), being a supporting plate having a fixed curvature; an elastic back plate (20), being a plate connected to the supporting back plate (10) and being elastically deformable so as to change the curvature; and an adjusting device (40), for adjusting the curvature of the elastic back plate (20). The adjusting device (40) is used to change the curvature of the elastic back plate, such that the display screen (30) can be curved into different arc shapes, improving the applicability of the curvature adjustment device of the curved display screen (30).
