L-Shaped Support Structure for High Panel Ratio Display Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display panel assemblies in smartphones have a relatively small panel ratio, which compromises user experience by limiting the screen size and efficiency of space utilization.
Innovation Solution
A display panel assembly design featuring an L-shaped support structure with reduced side wall thickness, combined with an in-mold injection molding process for a decorative ring, allows for a more compact and rigid assembly that increases the display panel ratio without expanding the device's overall width, using metallic or non-metallic materials for enhanced strength and reduced volume.

1Length of moving object
If the side wall thickness of the support is reduced, then the device width is reduced and panel ratio is increased, but the structural strength may be compromised
Solution Approach 1:
The support uses composite material construction combining aluminum alloy frame with reinforcing ribs, creating a structure that achieves high strength-to-weight ratio. The aluminum alloy material provides both lightweight properties and sufficient structural strength despite reduced wall thickness
Solution Approach 2:
The support structure is segmented into multiple components including side walls, bottom wall, and reinforcing ribs. This segmentation allows optimization of each component's thickness and strength independently, enabling reduced overall width while maintaining structural integrity through strategic reinforcement placement
2Area of stationary object
If the display panel size is increased to improve panel ratio, then user experience is improved, but the device overall width would increase
Solution Approach 1:
The support structure utilizes three-dimensional spatial optimization with the L-shaped configuration and strategically positioned reinforcing ribs. This dimensional approach allows the display panel to extend further while the support structure maintains compact width through vertical and depth-oriented reinforcement rather than horizontal expansion
Solution Approach 2:
The support structure applies local quality enhancement by concentrating reinforcement only where structurally necessary (at corners and along edges with reinforcing ribs), rather than uniformly thickening the entire structure. This allows maximum display area within minimum device width constraints

AI summary
A display panel assembly includes a support, a display panel, a cover plate, and a decorative ring. The support includes a first support component and a second support component. The second support component includes a bottom wall and a side wall bent from the bottom wall. A bottom surface of the first support component is fixed to the bottom wall. A side surface of the first support component faces the side wall. The display panel is fixed to a top surface of the first support component. The cover plate is disposed on the display panel. The decorative ring is disposed on a top end of the side wall away from the bottom wall and joined to a side of the cover plate.
