Display Back Plate Bulging Sections Stability Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display devices increase in size, the thickness of the mounting section also increases, making it difficult to maintain a thin profile while ensuring stability and preventing inclination and vibration, which existing technologies have not effectively addressed.
Innovation Solution
The display device incorporates a back plate with multiple mounting sections, vertically extending bulging sections, and a laterally extending bulging section, allowing for stable mounting while minimizing thickness, by distributing the holding members' load effectively and enhancing structural rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the mounting section size is increased to suppress inclination and vibration, then the stability and rigidity are improved, but the overall thickness of the display device increases
Solution Approach 1:
The patent transitions from a conventional flat mounting section to a three-dimensional structure by adding bulging sections that extend in the thickness direction. This dimensional change allows the mounting section to provide enhanced rigidity and stability through vertical extension rather than horizontal expansion, thereby improving stability without proportionally increasing overall device thickness.
Solution Approach 2:
The mounting section is divided into multiple discrete bulging sections rather than a single continuous structure. This segmentation allows for optimized load distribution across multiple localized support points, enabling the mounting section to achieve high rigidity with reduced material usage and minimized overall thickness.
2Strength
If the mounting section size is increased to prevent vibration, then the mechanical strength is improved, but the device complexity increases
Solution Approach 1:
The patent merges the mounting section with the back plate into a single integrated structure. The bulging sections are formed as integral parts of the back plate rather than separate components, which simplifies the overall device structure while maintaining the mechanical strength needed to prevent vibration. This integration eliminates the need for additional fasteners or assembly steps.
3Reliability
If multiple holding members are mounted to improve stability, then the reliability is improved, but the mounting section area must increase
Solution Approach 1:
The patent applies local quality by creating discrete bulging sections at specific locations on the back plate rather than uniformly thickening the entire mounting section. Each bulging section is strategically positioned to provide localized reinforcement where holding members need to be mounted, enabling multiple reliable mounting points without requiring a large overall mounting section area.

AI summary
Provided is a display device that can be held by a holding member in a stable state while increase in thickness is suppressed. The display device includes a display panel that displays an image and a back plate that holds the display panel. The back plate has mounting sections, a plurality of vertically bulging sections, and a laterally bulging section. The mounting sections are disposed on a plurality of positions on an edge part of one end of the back plate, and holding members that hold the display device are mounted to the mounting sections respectively. The vertically bulging sections bulge out from a reference surface of the back plate, and extend from near one ends of the mounting sections to an edge part of the other end of the back plate on an opposite side from the one end of the back plate. The laterally bulging section bulges out from the reference surface, extends along an edge of the other end of the back plate, and has a length larger than a distance between the vertically bulging sections adjacent to each other.
