Alternating Support Bars for Flexible Display Flatness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display modules often fail to maintain flatness when unwound, leading to suboptimal image presentation and user experience.
Innovation Solution
A display device configuration that includes a display module, a first support film, a second support film, first support bars on the lower surface of the first support film, and second support bars on the upper surface of the second support film, with the bars alternately arranged to provide enhanced flatness support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible display module is unwound, then it becomes accessible for use, but it cannot maintain flatness
Solution Approach 1:
The patent employs flexible support films with integrated support bars that can adapt to the display module's state. The support films are designed to be flexible enough to allow winding/unwinding operations while containing rigid support bars that maintain flatness when the module is unwound and in use.
Solution Approach 2:
The support structure is divided into multiple discrete support bars arranged within the support films. This segmentation allows the support function to be distributed across multiple elements, providing adequate flatness maintenance while allowing the overall structure to remain flexible for winding operations.
2Shape
If support structures are added to maintain flatness, then flatness is improved, but device complexity increases
Solution Approach 1:
The patent combines the support function with the existing flexible film structure by integrating support bars within the support films. This merging approach eliminates the need for separate, complex support mechanisms while achieving the flatness maintenance function.
Solution Approach 2:
The support films serve multiple functions: they provide structural support through integrated bars, maintain flexibility for winding operations, and ensure flatness when unwound. This multi-functionality reduces the need for additional dedicated components, thereby limiting complexity increase.

AI summary
A display device includes a display module, a first support film disposed under the display module, a second support film disposed under the first support film, a plurality of first support bars disposed on a lower surface of the first support film between the first support film and the second support film, and a plurality of second support bars disposed on an upper surface of the second support film between the first support film and the second support film. The plurality of first support bars and the plurality of second support bars are alternately arranged.
