Display Housing Reinforcement for Narrow Black Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing displays face challenges in reducing the black edge width while maintaining high screen-to-body ratio and ensuring anti-bending and anti-torsional strength, as support members limit further reduction of the black edge width.
Innovation Solution
Incorporating reinforcing members with extension portions that extend along the edges of the display housing, positioned between the screen and the bottom plate, enhancing mechanical strength and allowing the display panel to cover these extension portions, thereby reducing the black edge width and increasing the screen-to-body ratio without compromising anti-bending and anti-torsional performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If support members are disposed on four edges of the housing to reinforce edge portions and improve anti-bending and anti-torsional strength, then the housing can keep in a rectangular shape and resist deformation, but the black edge width cannot be further reduced and the screen-to-body ratio cannot be further increased
Solution Approach 1:
The reinforcing member is designed with a specific structure that includes a first extension portion extending along the third edge and a second extension portion extending along the first edge, creating localized reinforcement at critical areas (edges and corners) rather than uniform reinforcement throughout the housing. This allows the housing to maintain strength where needed while minimizing the overall footprint of reinforcing structures.
Solution Approach 2:
The reinforcing member protrudes from the inner surface of the bottom plate in the thickness direction, utilizing the third dimension (depth/thickness) to provide structural reinforcement. This vertical dimension allows the reinforcing member to strengthen the housing without occupying horizontal space that would increase the black edge width, effectively solving the contradiction between strength and edge width reduction.
2Length of stationary object
If the display panel covers the first extension portion to increase screen-to-body ratio, then the black edge width is reduced, but the mechanical strength at the third edge must be maintained
Solution Approach 1:
The reinforcing member is segmented into multiple extension portions: a first extension portion along the third edge and a second extension portion along the first edge. This segmentation allows the reinforcing member to provide targeted strength at specific locations (edges and corners) while allowing the display panel to cover other areas, thereby reducing the black edge width without compromising overall structural integrity.
Solution Approach 2:
The reinforcing member is made of a material with higher stiffness than the housing material, creating a composite structure where the reinforcing member provides enhanced strength at critical areas. This material differentiation allows the display panel to extend closer to the edges (reducing black edge width) while the high-stiffness reinforcing member maintains the necessary mechanical strength at the third edge and corners.
