Interactive Display Impact Resistance via Adapter Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interactive touch screens, particularly those with liquid crystal display panels, are vulnerable to damage from impacts and stress, which can cause display defects like light leakage and color bands due to the sensitivity of newer technologies such as OLEDs to applied or residual stress.
Innovation Solution
An adjustable adapter plate is used to create a mounting surface on the display chassis level with the liquid crystal display panel, combined with an optically clear protective plate and compliant adhesives or structures to absorb and dissipate impact energy, reducing stress on the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the interactive cover glass is extended to the edge with seamless interactive area, then the interaction capability is improved, but the vulnerability to contamination and damage increases
Solution Approach 1:
The patent divides the protective function into multiple layers: a first protective plate attached to the display panel and a second protective plate attached to the chassis, with the interactive cover glass in between. This segmentation allows each layer to handle specific protective functions while maintaining the seamless interactive area.
Solution Approach 2:
The patent implements protective plates and compliant adhesive structures before impact or contamination occurs. The compliant adhesive layer acts as a cushion that absorbs impact energy, and the protective plates prevent contamination from entering seams, addressing the harmful factors before they can damage the display.
2Illumination intensity
If newer display technologies like OLED are used to improve display quality, then the visual performance is improved, but the sensitivity to stress and impact damage increases
Solution Approach 1:
The patent uses a compliant adhesive layer between the protective plates and the display panel. This flexible film structure absorbs impact energy and reduces stress transmission to the sensitive OLED panel, protecting it from damage while maintaining display quality.
Solution Approach 2:
The patent creates a composite protective structure combining rigid protective plates with a compliant adhesive layer. This composite material approach provides both structural support and stress absorption, protecting the sensitive display technology from impact damage.
3Shape
If the protective bezel is minimized to achieve flush mounting, then the aesthetic appearance is improved, but the protection against side impacts is reduced
Solution Approach 1:
The patent moves the protective function from the horizontal dimension (bezel) to the vertical dimension by attaching protective plates to both the display panel and chassis. This dimensional shift allows for minimal bezel while maintaining protection through the layered structure.
Solution Approach 2:
The patent introduces adjustable adapter plates as intermediaries between the chassis and the protective structure. These adapter plates create a mounting surface that is level with the display panel, enabling flush mounting while the protective plates provide the necessary impact protection.

Function Achieved in This Case
This configuration enhances the impact resistance of the display system, preventing damage from drops and side impacts and minimizing display defects by isolating the liquid crystal display panel from external stresses.
