Display Device Supporting Structure for Lateral Displacement Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with reduced chassis thickness and weight face challenges in securing plate-type display sections effectively against impulsive loads, leading to increased displacement and adverse effects on internal components.
Innovation Solution
A display device structure featuring a supporting portion with a first surface and a second surface that rises vertically to receive the side surface of the display section, combined with a cushioning element to absorb impulsive loads, and an L-shaped cross-section design to efficiently utilize internal space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of stationary object
If the chassis thickness is reduced to achieve reduced device size and weight, then the device size and weight are reduced, but the securing-and-holding function for the display section deteriorates under impulsive loads
Solution Approach 1:
The supporting portion extends in the widthwise direction to form a receiving surface that faces the side surface of the display section. This dimensional extension provides lateral support without increasing the thickness direction, thereby maintaining the reduced chassis thickness while improving the securing function against impulsive loads.
Solution Approach 2:
The receiving surface of the supporting portion is given higher rigidity locally by extending in the widthwise direction and facing the side surface of the display section. This localized rigidity enhancement specifically addresses the securing function at the critical interface with the display section without requiring the entire chassis to be thicker.
2Volume of stationary object
If the receiving surface of the supporting portion is made easily deformable to provide necessary space, then internal space is increased, but the rigidity of the supporting portion is reduced, causing greater display section displacement
Solution Approach 1:
The supporting portion extends in the widthwise direction rather than increasing thickness, providing internal space in the thickness direction while maintaining rigidity through the lateral extension. The receiving surface faces the side surface of the display section, ensuring rigidity is preserved where needed for support.
3Volume of stationary object
If the supporting portion thickness is reduced to provide space in the opposite side from the receiving surface, then internal space utilization is improved, but the rigidity of the receiving surface portion is degraded
Solution Approach 1:
The supporting portion compensates for reduced thickness by extending in the widthwise direction to form a receiving surface that faces the side surface of the display section. This lateral extension provides the necessary rigidity through increased moment of inertia in the bending direction, allowing thickness reduction while maintaining support capability.

AI summary
There is provided a display device comprising: a plate-type display section with a display surface; a front-surface plate placed on a front surface of the display surface; and a supporting portion for supporting the display section and the front-surface plate. The supporting portion includes a first surface adapted to support the front-surface plate, and a second surface which is formed in such a way as to rise up substantially vertically from the first surface such that the second surface faces a side surface of the display portion and, further, includes at least a rising base end portion thereof.
