Solution Overview
Problem
Existing display devices face challenges in mitigating crack generation and propagation due to external impacts, particularly in the window component made of glass or transparent plastic materials.
Innovation Solution
A window design featuring a pattern part with alternating first and second pattern parts, each with distinct opening portions and resin filling, which enhances impact absorption and crack prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a window is made of glass or transparent plastic material to protect the display panel, then the display panel is protected from external scratches and impacts, but the window is susceptible to crack generation and propagation due to external impacts
Solution Approach 1:
The window is divided into a display part and a pattern part with opening portions. The pattern part contains multiple opening portions that segment the structure, preventing crack propagation by creating discontinuities in potential crack paths while maintaining overall protective function.
Solution Approach 2:
The pattern part is designed with opening portions creating a porous-like structure. This allows the window to absorb impact energy through controlled deformation around the openings while preventing cracks from spreading across the entire window surface, thus maintaining protection capability while reducing crack susceptibility.
2Object-affected harmful factors
If the window is designed with a pattern part containing opening portions to prevent crack propagation, then crack generation and propagation are mitigated, but the structural strength may be reduced
Solution Approach 1:
The window structure is designed with different local qualities: the display part maintains solid continuous structure for strength, while the pattern part contains opening portions for crack prevention. This local differentiation allows each region to optimize its function without compromising overall structural integrity.
Solution Approach 2:
The window combines different structural configurations (solid display part and patterned part with openings) to create a composite structure that leverages the strengths of both approaches: continuous material for strength and discontinuous structure for crack resistance.
3Object-affected harmful factors
If the window includes a pattern part with opening portions to absorb impact, then external impacts are lessened, but the manufacturing complexity increases
Solution Approach 1:
The manufacturing process is segmented into forming the display part and pattern part separately, with the pattern part containing pre-designed opening portions. This segmentation allows for specialized manufacturing techniques for each part while maintaining overall process efficiency.
Solution Approach 2:
The design incorporates specific geometric parameters for the opening portions (size, shape, distribution) that can be optimized to achieve desired impact absorption characteristics. By carefully selecting these parameters, the window achieves effective impact mitigation while maintaining manufacturability through standardized design elements.

AI summary
A window includes a display part and a pattern part. The display part has first sides extending in a first direction and second sides extending in a second direction transverse to the first direction. The pattern part surrounds the display part in a view in a third direction perpendicular to the first direction and the second direction. The pattern part includes a first pattern part extending along a side among the first sides and the second sides of the display part and includes a first pattern in the window, and a second pattern part adjacent to a transition region of the display part connecting a first side among the first sides to a second side among the second sides and includes a second pattern in the window. In the view, a shape of the first pattern is different from a shape of the second pattern.
