Curved Display Rear Chassis Segmented Reinforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat electronic display devices experience trapezoidal distortion at large viewing angles, and existing curved display solutions require bulky reinforcing brackets to maintain curvature, compromising slimness and aesthetics.
Innovation Solution
A curved electronic display device design utilizing a rear chassis assembly with a substrate and side walls, reinforced by sheets with matching curvature, which maintains structural integrity without increasing thickness and allows for efficient assembly and improved yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bulky reinforcing bracket is used to maintain the curvature of the electronic display device, then the structural strength is improved, but the thickness and appearance are worsened
Solution Approach 1:
The reinforcing bracket is divided into multiple segments (first bracket segment, second bracket segment, third bracket segment) that are distributed around the curved electronic display panel. This segmentation allows the bracket to provide structural support while reducing the overall thickness and improving appearance compared to a single bulky bracket.
Solution Approach 2:
The reinforcing bracket segments are nested within the housing structure, with the bracket segments positioned between the curved electronic display panel and the housing. This nesting arrangement allows the bracket to provide structural support while remaining compact and not increasing the overall device thickness.
2Adaptability or versatility
If a curved electronic display device is designed with multiple viewing angles, then the viewing experience is improved, but the structural complexity is worsened
Solution Approach 1:
The housing is divided into multiple segments (first housing segment, second housing segment, third housing segment) that correspond to different viewing angles. Each housing segment is equipped with its own reinforcing bracket segment, allowing the device to provide multiple viewing angles while keeping each individual structural element simple and manageable.
Solution Approach 2:
Different portions of the housing and bracket structure are designed with different properties optimized for their specific functions. The first, second, and third housing segments have different geometries and support requirements tailored to their respective viewing angles, allowing each local region to be optimized without complicating the entire structure.

AI summary
An electronic display device is provided. The electronic display device includes an electronic display panel and a rear chassis assembly. The rear chassis assembly includes a bottom wall, a first and a second side wall, and a first and a second sheet. The first and the second side walls are respectively disposed at two opposite edges of the bottom wall. The electronic display panel is positioned in an accommodation space defined by the first side wall, the second side wall, and the bottom wall. The first and second sheets are respectively fixed on the first and second side walls. The curvature of the first sheet corresponds to the curvature of the first side wall, and the curvature of the second sheet corresponds to the curvature of the second side wall.
