AI Technical Summary

Technical Problem

When the display is expanded, the support performance of the folding area is poor, resulting in bending.

Method used

A foldable screen is designed, using a flexible screen and multiple folding units. The folding unit includes installation brackets and mobile parts. The mobile parts can move along the direction of the installation bracket away or near the flexible screen. The folding unit limits the relative position of the installation of the bracket and supports the folding area of ​​the flexible screen.

Benefits of technology

Effectively improve the support performance of the display when expanding the state, prevent bending, ensure that the flexible screen maintains a flat state, and at the same time, the folding action can be successfully completed during folding.

Abstract

The present application relates to a foldable screen, including a flexible screen and a plurality of folding units, wherein the folding unit includes a mounting bracket and a moving member, wherein the mounting bracket is connected to one side of the flexible screen along the thickness direction of the flexible screen, and the moving member is mounted on the mounting bracket and can move along the mounting bracket toward or away from the flexible screen, so that the foldable screen can be folded or unfolded. A plurality of raised portions are arranged at intervals along the circumference of the moving member, and the raised portions include a first body portion and a second body portion, wherein one end of the first body portion is connected to the moving member, and the other end is connected to the second body portion, and the cross-sectional area of ​​the second body portion is larger than the cross-sectional area of ​​the first body portion, so that adjacent moving members can mesh with each other, and are used to connect adjacent folding units, limit their relative positions, and enable the folding units to support the flexible screen.
