Title:
FOLDABLE SCREEN SUPPORTING PLATE AND MANUFACTURING METHOD THEREFOR, ROTATING SHAFT MECHANISM, AND FOLDABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/001760
Kind Code:
A1
Abstract:
The present application provides a foldable screen supporting plate (100), a rotating shaft mechanism (200), a foldable device, and a manufacturing method for the foldable screen supporting plate (100). A shielding layer (130) is provided on a lower structural layer (110) having cavities (111) to cover openings (112) of the cavities (111), and an upper filling layer (120) is provided on the shielding layer (130). Alternatively, the upper filling layer (120) is provided on the lower structural layer (110) having the cavities (111), and through holes (122) communicated with the openings (112) are provided on the upper filling layer (120) corresponding to the openings (112) of the cavities (111). The two modes can prevent raw materials from entering the cavities (111) through the openings (112) during the formation of the upper filing layer (120), such that the upper filling layer (120) has a flat surface (121) with good flatness. A foldable screen (300) is well supported by means of the flat surface (121) of the foldable screen supporting plate (100), such that the foldable screen (300) has a better light and shadow display effect and a longer service life. A plurality of foldable screen supporting plates (100) are arranged in sequence and rotatably connected to each other, the rotating shaft mechanism (200) is bendable, when the rotating shaft mechanism (200) is completely unfolded, the flat surfaces (121) of all the foldable screen supporting plates (100) have smaller steps and better flatness, and the plurality of flat surfaces (121) can well support the foldable screen (300).
