Curved Display Back Frame Reinforcement with Metal Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-flat panel display modules face issues with maintaining the intensity and curved feature of their back frames, as plastic frames are easily deformable and metal frames experience recovery tension, leading to quality defects.
Innovation Solution
A support structure is fixed to the outer surface of the back frame, which can be solid or hollow, made of rigid material, and includes reinforcing ribs to enhance the outer frame's intensity and maintain the curved feature, using fixing holes for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a plastic back frame is used, then the manufacturing cost is reduced and ease of manufacture is improved, but the frame intensity is insufficient and the frame is easily deformable
Solution Approach 1:
The patent combines plastic material with metal reinforcing ribs to create a composite back frame structure. The plastic provides ease of manufacture and cost effectiveness, while the metal ribs provide the necessary strength and deformation resistance, resolving the contradiction between ease of manufacture and frame intensity.
Solution Approach 2:
The back frame is segmented into multiple components: a plastic base frame and separate metal reinforcing ribs. This segmentation allows each component to be optimized for its specific function - the plastic for manufacturing ease and the metal ribs for structural strength - while working together as an integrated system.
2Strength
If a metal back frame is used, then the frame intensity is improved, but recovery tension occurs and the curved feature cannot be maintained for long
Solution Approach 1:
The composite structure of plastic and metal ribs prevents the recovery tension problem inherent in pure metal frames. The plastic material provides flexibility and damping that prevents the metal ribs from generating recovery tension, thereby maintaining the curved feature stability over time while preserving frame intensity.
Solution Approach 2:
Metal reinforcing ribs are strategically positioned at specific locations on the back frame where additional strength is needed. This localized application of metal provides frame intensity where required while the overall plastic structure maintains the curved feature stability, avoiding the uniform metal construction that causes recovery tension.
3Strength
If reinforcing ribs are added to the back frame, then the frame intensity is improved, but the device complexity increases
Solution Approach 1:
The reinforcing ribs are designed as separate, discrete components rather than an integrated complex structure. This segmentation allows for simpler manufacturing of individual ribs that can be easily attached to the plastic frame, reducing overall device complexity while providing the necessary frame intensity through modular assembly.

AI summary
Disclosed are a non-flat panel display module and the back frame support structure thereof. The non-flat panel display module comprises a non-flat display panel and an outer frame. The outer frame comprises a back frame. The back frame has a non-flat shape in accordance with a back surface of the non-flat display panel and is fixed to the back surface of the non-flat display panel. At least one support structure is fixed to the outer surface of the back frame. The support structure is fixed to an outer surface of the back frame. Therefore, the support structure can strengthen the outer frame intensity and to ensure the intensity and the curved feature of the non-flat panel display module.
