Flexible Display Curvature Control via Frame Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display bodies with non-uniform stiffness can experience buckling when attempting to achieve curvature deformation, leading to image quality degradation.
Innovation Solution
A display design featuring a flexible plate member with a frame member extending in one direction, allowing the plate member and display body to take any desired shape, with the frame member's shape determining the curvature of both the plate member and the display body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the left and right side plates of the display body are brought close to each other for curvature deformation, then the display body can achieve curved shape, but buckling occurs due to non-uniform stiffness, leading to degradation of image quality
Solution Approach 1:
The display body is divided into multiple independent curvature control units (first, second, third, and fourth curvature control units) that can be adjusted separately. Each unit contains curvature control members (screws or cam mechanisms) that independently control the curvature of specific regions, allowing differential adjustment to compensate for non-uniform stiffness and prevent buckling while achieving the desired curved shape.
2Adaptability or versatility
If the display body is made flexible to allow curvature deformation, then any desired shape can be achieved, but structural stability decreases, causing buckling
Solution Approach 1:
The display body incorporates adjustable curvature control mechanisms that allow dynamic adaptation of structural stiffness. The curvature control members (screws or cam mechanisms) enable the structure to be rigid when flat and become flexible when curved, providing optimal stability for each configuration. This dynamic adjustment resolves the contradiction between shape adaptability and structural stability.
