Display Panel Assembly With Thinner Side Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphone display panel assemblies have a relatively small panel ratio, which limits user experience due to reduced screen size and inefficient space utilization.
Innovation Solution
A display panel assembly design that includes a support with a thinner side wall and a press-formed structure, combined with an in-mold injection molding process for a decorative ring, allows for a reduced thickness and width, increasing the display panel ratio without increasing the overall device size, using materials like steel or magnesium alloy for strength and rigidity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the support structure is made thicker to ensure structural integrity, then strength and rigidity are improved, but the device width and volume increase
Solution Approach 1:
The support structure employs different thicknesses in different regions: the first support portion has a first thickness while the second support portion has a second thickness that is less than the first thickness. This local differentiation allows the structure to maintain necessary strength where required while reducing volume where full strength is not needed, directly resolving the contradiction between structural integrity and device volume.
2Strength
If the side wall thickness is increased to maintain structural strength, then strength is improved, but the device width increases
Solution Approach 1:
The side wall is designed with non-uniform thickness, where the first side wall portion has a first thickness and the second side wall portion has a second thickness that is less than the first thickness. This local quality variation enables the structure to maintain adequate strength in critical areas while minimizing the overall device width, effectively resolving the contradiction between structural strength and device width.

AI summary
A display panel assembly includes a support, a display panel, a cover plate, and a decorative ring. The support includes a bottom wall and a side wall bent from the bottom wall. A thickness of the side wall is less than a thickness of the bottom wall to form the support. The display panel is fixed to the bottom wall of the support. The cover plate is disposed on the display panel. The decorative ring is disposed on a top end of the side wall of the support away from the bottom wall of the support and joined to a side of the cover plate.
