Curved Display Fixing Members Assembly Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curved display devices have complex assembly procedures and require numerous components, leading to manufacturing challenges such as rebound and poor precision control during the stamping process, and difficulties in precisely assembling curved brackets.
Innovation Solution
A display device design featuring a first and second arc-shaped fixing member, an optical element, and an optical film assembly, where the second arc-shaped fixing member is connected to the edge of the first, forming a curved surface, with the optical element and film assembly adjacent to each other, reducing the number of supporting components and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple components (curved supporter and arc frames) are used to form the back plate structure, then the desired curved status is achieved, but the assembly complexity increases significantly
Solution Approach 1:
The patent merges the curved supporter and arc frames into a single integrated back plate structure. The back plate is formed as one piece with both the curved support function and the arc-shaped frame structure incorporated, eliminating the need for separate components and complex assembly procedures while maintaining the desired curved display status
Solution Approach 2:
The back plate structure serves multiple functions simultaneously: it provides the curved support for the display panel, forms the structural frame, and maintains the arc-shaped geometry. This multi-functional design replaces the conventional multi-component system with a single structure that performs all necessary functions
2Shape
If stamping process is used to manufacture arc components, then the curved shape is achieved, but rebound and poor precision control occur
Solution Approach 1:
The patent changes the manufacturing parameters by switching from stamping process to injection molding process. Injection molding allows for better precision control and eliminates rebound issues by forming the back plate as a single molded piece with precise arc geometry, directly addressing the precision control problems associated with stamping
3Shape
If pipe bending process is used to fabricate curved bracket, then the curved structure is achieved, but precise assembly becomes difficult
Solution Approach 1:
The patent combines the curved bracket function with the back plate structure itself. The back plate is designed with integrated arc-shaped frames that provide the necessary curved support without requiring separate curved brackets, thereby simplifying the assembly process while maintaining the curved structure

AI summary
A display device includes a first arc-shaped fixing member, a second arc-shaped fixing member, an optical element, an optical film assembly and a display panel. The first arc-shaped fixing member is disposed corresponding to the second arc-shaped fixing member, and the second arc-shaped fixing member is connected to the edge of the first arc-shaped fixing member. The optical element is disposed between the first arc-shaped fixing member and the second arc-shaped fixing member so as to form a curve surface. The optical film assembly is disposed adjacent to the optical element. The display panel is disposed corresponding to the second arc-shaped fixing member and located at one side of the second arc-shaped fixing member away from the optical element.
