Thin Display Chassis with Recessed Plate for Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display panels increase in size, providing additional rigidity while maintaining a thin thickness in display apparatuses is challenging, as increasing the depth of the chassis through drawing processes is not preferable due to thickness reduction requirements.
Innovation Solution
A chassis structure comprising a first chassis member with a recess and a second plate-shaped chassis member that covers the opening of the recess, providing desired strength and rigidity while maintaining a thin profile, and enhancing heat dissipation by approximating the surface to a planar shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the depth of the chassis is increased by a drawing process to provide display panel rigidity, then the strength and rigidity of the chassis are improved, but the thickness of the entire display apparatus increases
Solution Approach 1:
The chassis is divided into multiple members: a first chassis member with a recess formed by a drawing process, and a second chassis member in a plate shape that covers the opening of the recess. This segmentation allows the rigidity-enhancing drawing process to be applied only where needed (in the recess) while maintaining overall thinness through the plate-shaped cover member.
Solution Approach 2:
The second chassis member is mounted on the first chassis member, covering the opening of the recess. This nested configuration allows the drawing process to be contained within the recess structure while the outer plate-shaped member provides a thin, flat profile for the overall chassis assembly.
2Length of stationary object
If a thin chassis structure is used to reduce display apparatus thickness, then the overall thickness is reduced, but the rigidity and strength of the display panel decrease
Solution Approach 1:
The drawing process is applied locally to form a recess in the first chassis member, creating localized structural reinforcement. The plate-shaped second chassis member then covers this recessed area, providing distributed structural support. This local quality approach allows thin overall thickness while maintaining rigidity through strategic structural features.
3Weight of stationary object
If the chassis structure is made thin to reduce weight and thickness, then the weight and thickness are reduced, but the heat dissipation capability of the display panel decreases
Solution Approach 1:
The second chassis member is configured to approximate the surface to a planar shape, creating a flat heat dissipation surface. This dimensional configuration allows the thin chassis structure to provide effective heat dissipation through its planar surface area, which facilitates thermal radiation and convection, while maintaining reduced weight and thickness.

AI summary
A display apparatus including: a display panel; and a chassis structure which holds the display panel, wherein the chassis structure includes a first chassis member in which a recess whose opening opens toward a display panel side is formed, and a second chassis member which is in a plate shape, and mounted on the first chassis member, covering at least a portion of the opening of the recess.
