Decorative Layer Protrusions Blur Display Boundary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing decorative layers for display devices face a challenge in achieving compatible color and physical properties, leading to conspicuous color differences with the transparent plate, which affects the aesthetic appearance.
Innovation Solution
A decorative layer-attached transparent plate design featuring protrusions or recesses at the end portion, with specific dimensions and shapes that blur the boundary between the decorative layer and the transparent plate, reducing color differences and maintaining required physical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the decorative layer is formed with a smooth end portion to maintain physical properties, then the boundary between the decorative layer and transparent plate becomes conspicuous, but if the end portion is formed with protrusions or recesses to blur the boundary, then the manufacturing complexity increases
Solution Approach 1:
The decorative layer is designed with different local structures: the main body maintains a smooth surface to ensure adhesion and hardness, while the end portion features protrusions or recesses to blur the boundary. This local differentiation resolves the contradiction by applying different structural qualities to different regions of the same component.
Solution Approach 2:
The protrusions and recesses at the end portion of the decorative layer create a non-smooth, irregular boundary shape that appears blurred to the human eye. This curvature-based approach transforms the sharp linear boundary into a softened transitional zone, reducing visual conspicuousness without compromising the overall structural integrity.
2Manufacturing precision
If the decorative layer uses black color to match the display panel in non-display state, then the color difference becomes conspicuous at the boundary, but if the decorative layer uses a different color to mask the boundary, then the aesthetic appearance is impaired
Solution Approach 1:
The decorative layer uses black color in its main body to match the display panel during non-display states, while the end portion incorporates protrusions or recesses that create a blurred transition zone. This local differentiation allows the color matching function to be fulfilled in the display area while the structural feature at the boundary provides the aesthetic blending effect.
Solution Approach 2:
The protrusions and recesses at the end portion act as an intermediary structure between the black decorative layer and the transparent plate. This intermediate structural feature creates a gradual visual transition that mediates the harsh color contrast, allowing the black color to be used without creating a conspicuous boundary.
3Reliability
If the decorative layer is made with high adhesion to the transparent plate, then the physical properties are satisfied, but the color difference at the boundary becomes more conspicuous
Solution Approach 1:
The decorative layer maintains high adhesion strength in its main body through proper material selection and bonding processes, while the end portion features protrusions or recesses that reduce the visual impact of the boundary. This local differentiation allows the adhesion requirement to be fulfilled without compromising aesthetic appearance.
