Display Boundary Gradation Pattern for Uniform Off-State Appearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses exhibit a noticeable visual difference between the display and non-display regions when powered off, due to differences in light reflection and absorption, which degrades the design aesthetics.
Innovation Solution
A display apparatus design featuring a light shielding layer and a reflective layer with specific thickness and material properties, along with a gradation pattern, to minimize visual differences between the display and non-display regions by matching their light reflection and transmission characteristics, making the boundary between them virtually imperceptible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a light shielding layer is added to the non-display region, then light absorption is improved, but device complexity increases
Solution Approach 1:
The patent combines the light shielding layer and reflective layer into a single integrated structure at the boundary between display and non-display regions. This merged structure simultaneously provides light shielding and light reflection functions, reducing the number of separate components while achieving the desired optical effect of minimizing visual boundaries.
Solution Approach 2:
The light shielding and reflective properties are applied locally at the boundary region rather than uniformly across the entire display apparatus. The light shielding layer and reflective layer are positioned specifically where needed to mask the boundary, allowing other regions to maintain their original optical characteristics.
2Illumination intensity
If a reflective layer is added to match light transmission characteristics, then visual uniformity is improved, but manufacturing complexity increases
Solution Approach 1:
The patent optimizes the thickness and material properties of the reflective layer to achieve specific light transmission characteristics. By carefully controlling the optical parameters (thickness, refractive index) of the reflective layer, the light transmission in the non-display region is matched to the display region, creating visual uniformity while using standard manufacturing techniques.
Solution Approach 2:
The patent uses composite material structures combining the light shielding layer and reflective layer with different optical properties. This composite approach allows tuning of the overall optical characteristics to match light transmission between display and non-display regions while maintaining manufacturability through established multi-layer deposition techniques.
3Shape
If the boundary between display and non-display regions is made less visible, then aesthetic design is improved, but light reflection control becomes more complex
Solution Approach 1:
The patent employs optical property changes in the light shielding and reflective layers to reduce the visual contrast at the boundary. By controlling the reflectivity and transmittance characteristics of these layers, the boundary becomes less visually distinct, improving aesthetic appearance while using optical property control rather than complex mechanical or electronic systems.

AI summary
A display apparatus includes a panel located in front of a display module, a pattern formed over the panel, and a reflective layer formed to overlap the pattern. At least one portion of the pattern provided closer to an edge of the panel allows for less transmittance of light and other portions of the pattern.
