Partially Curved Display Device Panel Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional method of manufacturing large-sized curved display devices requires increased manufacturing equipment costs and reduces yield due to the need for entire panel replacement upon damage during the bending process.
Innovation Solution
A large-sized display device with a partially curved design featuring a panel fixing plate with both curved and flat parts, allowing for separate manufacturing and attachment of curved and flat display panels, enabling partial replacement and reducing equipment size needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the entire display panel is bent to create a curved display device, then the immersive effect is improved, but the manufacturing equipment size must be increased and manufacturing costs increase
Solution Approach 1:
The display panel is divided into multiple separate panels (first display panel and second display panel) that can be manufactured independently using standard equipment, then assembled together to form the complete curved display device. This segmentation allows standard manufacturing equipment to produce individual panels while achieving the desired curved configuration through assembly.
Solution Approach 2:
The curvature formation process is extracted from the main manufacturing process. Instead of bending the entire large display panel in one operation requiring large equipment, the curvature is formed on smaller individual panels that can be manufactured with standard equipment, and then these pre-curved panels are assembled together.
2Shape
If the entire display panel is bent to create a curved display device, then the immersive effect is improved, but manufacturing yield is reduced due to damage during bending
Solution Approach 1:
The display panel is divided into multiple separate panels that can be manufactured independently. If damage occurs during curvature formation, only the affected individual panel needs to be replaced rather than discarding the entire display device, thereby improving manufacturing yield.
Solution Approach 2:
The design allows for selective replacement of damaged panels. When damage occurs during the curvature formation process, the damaged panel can be discarded and replaced with a new one, while the undamaged portions of the display device are recovered and reused, thus reducing waste and improving yield.
3Shape
If the entire display panel is bent to create a curved display device, then the immersive effect is improved, but replacement cost increases when damage occurs
Solution Approach 1:
The display panel is segmented into multiple independent panels that can be individually replaced. When damage occurs during curvature formation or operation, only the damaged individual panel needs to be replaced rather than replacing the entire display device, significantly reducing repair costs.
Solution Approach 2:
The modular design enables selective replacement of damaged panels. The damaged panel can be discarded and replaced with a new one, while the functional panels and mounting structure are recovered and reused, reducing overall replacement costs.

AI summary
A large-sized display device having a partially curved part, includes: a partially curved transparent panel fixing plate comprising a curved part, formed so as to have a predetermined curved surface, and a flat part, formed so as to be continuous with the curved part; a curved display panel formed so as to have a curved surface corresponding to the curved surface of the curved part for displaying an image through the panel fixing plate; and a flat display panel installed at the flat part for displaying an image through the panel fixing plate.
