Coverplate Display Module Assembly for Narrow-Bezel Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in reducing bezels due to the presence of edge wirings, leading to large bezel areas and reduced display ratios, which affect visual experience.
Innovation Solution
A display module design incorporating a middle frame connected to the display panel and coverplate with a filling glue to minimize bezel width, utilizing a groove and filling gaps to enhance adhesion and assembly compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If edge wirings are used in display panels, then electrical connections are achieved, but bezel width increases and display ratio decreases
Solution Approach 1:
The patent moves the wiring from the edge (2D plane) to the back surface (3D space) of the display panel. By routing wirings on the back surface and using a bending region to connect to edge terminals, the design eliminates the need for edge wirings that would increase bezel width, thus reducing bezel area while maintaining electrical connection reliability
Solution Approach 2:
The display panel is divided into distinct functional regions: a planar region for display, a bending region for wiring transition, and a bonding region for back surface connections. This segmentation allows the wiring structure to be separated from the visible display area, enabling reduced bezels while maintaining electrical functionality
2Reliability
If assembly boundary width is increased to ensure good assembly effect, then assembly reliability improves, but bezel area increases and display ratio decreases
Solution Approach 1:
The patent relocates the assembly interface from the front edge (affecting bezel width) to the back surface of the display module. The middle frame connects to the housing through the back surface, allowing sufficient assembly boundary width without increasing front bezel area, thus maintaining assembly reliability while reducing visible bezel area
Solution Approach 2:
The middle frame acts as an intermediary component that provides the assembly interface between the display panel and housing. By positioning the middle frame on the back surface with adequate width, it serves as the assembly boundary without impacting the front bezel dimensions, resolving the contradiction between assembly reliability and bezel area
