Incorporating a plastic layer around a glass substrate cover plate with no height difference, utilizing materials like PMMA and PC, and enhancing bonding through injection molding or roughening sidewalls to improve structural integrity and reduce manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glass substrate cover plate is used, then display reliability and appearance are improved, but susceptibility to external force impact increases
Solution Approach 1:
The patent applies beforehand cushioning by introducing a plastic layer between the glass substrate cover plate and the external environment. This plastic layer serves as a cushioning element that absorbs and mitigates external force impacts before they reach the fragile glass substrate, thereby protecting the display structure while maintaining the reliability benefits of the glass cover plate.
2Object-affected harmful factors
If a plastic layer is added around the cover plate, then protection against external force is improved, but height difference and appearance seamless integration worsen
Solution Approach 1:
The patent applies equipotentiality by designing the plastic layer to have the same height as the glass substrate cover plate, creating a flush surface. This height equivalence eliminates visible steps or gaps between components, achieving seamless appearance integration while the plastic layer continues to provide protective cushioning function.
3Ease of manufacture
If traditional bonding methods are used, then manufacturing process is simple, but bonding strength and structural integrity are insufficient
Solution Approach 1:
The patent applies composite materials by combining the glass substrate cover plate with a plastic layer to form a hybrid structure. This composite construction leverages the optical clarity and rigidity of glass together with the toughness and impact resistance of plastic, achieving superior bonding strength and structural integrity that neither material could provide alone.
