Display Housing Sidewall Height Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices have a significant non-display region that reduces their value and durability, as existing designs fail to minimize this area effectively while maintaining structural integrity.
Innovation Solution
A display device design featuring a housing with varying sidewall heights and adhesive coverage to minimize the non-display region, including a bottom plate with distinct edge regions and sidewalls that overlap the display panel, and an adhesive that covers part of the panel's surfaces for enhanced bonding and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If uniform sidewalls are used to support the display panel, then structural simplicity is maintained, but the non-display region cannot be minimized and durability is reduced
Solution Approach 1:
The patent applies local quality by varying the heights of sidewalls at different locations on the bottom plate. Specifically, the housing includes a first sidewall, second sidewall, third sidewall, and fourth sidewall with different heights, where the first and second sidewalls have greater heights than the third and fourth sidewalls. This localized variation in sidewall height allows the non-display region to be minimized in certain areas while maintaining structural support where needed, thereby resolving the contradiction between reducing the non-display region and maintaining structural simplicity.
2Reliability
If minimal adhesive coverage is used, then manufacturing cost is reduced, but durability and mechanical properties deteriorate
Solution Approach 1:
The patent applies dimensionality change by extending the adhesive not only in the planar direction but also vertically along the sidewalls. The adhesive extends from the bottom plate upward along the sidewalls to overlap with the display panel, creating a three-dimensional adhesive bonding path. This vertical extension increases the adhesive contact area significantly, improving durability and mechanical properties without proportionally increasing manufacturing cost, as the adhesive application follows the existing sidewall structure.
3Area of stationary object
If sidewalls are positioned to minimize non-display region, then product value is increased, but adhesive contact area is reduced
Solution Approach 1:
The patent resolves this contradiction by transitioning the adhesive bonding from a two-dimensional planar interface to a three-dimensional interface that extends vertically along the sidewalls. The adhesive is applied to cover portions of the bottom plate and extends upward to overlap with the display panel along the sidewalls. This vertical dimension provides additional adhesive contact area even when the horizontal non-display region is minimized, allowing both goals to be achieved simultaneously.
Solution Approach 2:
The patent applies segmentation by dividing the adhesive bonding into multiple zones: adhesive on the bottom plate, adhesive extending along different sidewalls, and adhesive overlapping with the display panel. This segmented approach allows the adhesive to be strategically positioned in multiple locations, maximizing the total adhesive contact area while maintaining a compact overall structure with minimized non-display region.
