Flexible Display Support Structure Reduces Bending Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible displays are prone to damage during bending due to excessive stress on the circuit in the bending area, leading to a reduced service life and potential open circuits, limiting the bending angle and overall display effectiveness.
Innovation Solution
A flexible display design comprising a flexible panel, a shell, and a support structure that includes a free end and a connecting end, where the support is rotatably connected to the shell and positioned between the display parts to reduce stress on the bending area, allowing for increased space and even stress distribution, thus preventing damage during bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bending angle of flexible display is increased to improve flexibility, then the bendability is improved, but the stress on the circuit in the bending area increases causing damage and reducing service life
Solution Approach 1:
A support structure is introduced as an intermediary component between the display panel and the external environment. This support structure includes a support body with a support surface that contacts the display panel, distributing the stress during bending and protecting the circuit from direct damage while enabling greater bendability.
Solution Approach 2:
The support structure is designed to provide protective cushioning to the bending area before damage can occur. By pre-positioning the support structure against the display panel, it creates a protective barrier that absorbs and distributes stress during bending operations, preventing circuit damage beforehand.
2Reliability
If the support structure increases space between display parts to reduce stress, then the service life is extended, but the device complexity increases
Solution Approach 1:
The support structure utilizes a thin film or shell design that provides structural support and stress distribution functionality without adding significant bulk or complexity. The support surface contacts the display panel directly, creating the necessary space to reduce stress while maintaining a sleek, simple overall structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The support structure effectively reduces stress on the bending area, preventing damage and extending the service life of the flexible display by allowing for greater flexibility and maintaining display quality.
Implementation Method 1
The support comprises a free end and a connecting end... as the support is in the first state and after the flexible display panel is bent, the support is located between the first display part and the second display part... increase the space between the first display part and the second display part on the other hand to reduce the bent deformation to reduce the stress of the bending part
Implementation Method 2
the connecting end is rotatably connected with one end of the shell... the support rotates around the connecting component
