Vehicle Display Shielding for Non-Rectangular Image Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems fail to improve image quality when using non-rectangular display areas, particularly in moving vehicles where image presentation is critical for driver assistance information.
Innovation Solution
A display system with a shielding member that defines the shape of light emerging from a non-rectangular display area, ensuring the light conforms to the outer peripheral shape of the display area, enhancing image quality and visibility in moving vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a rectangular display area is used with a conventional shielding member, then the circuit section and wire bonding portion can be hidden, but the image quality cannot be improved for non-rectangular display areas
Solution Approach 1:
The shielding member's opening is designed with a peripheral edge shape that locally conforms to the outer peripheral shape of the display area. This local adaptation allows the shielding member to effectively mask unwanted regions while preserving the specific non-rectangular geometry of the display area, thereby improving image quality without sacrificing adaptability to different display area shapes
Solution Approach 2:
The invention moves away from the conventional rectangular opening design to an asymmetric opening shape that matches the specific non-rectangular display area geometry. This asymmetric design allows the shielding member to perfectly align with the display area's outer peripheral shape, improving image quality by eliminating geometric mismatches while maintaining adaptability to various asymmetric display configurations
2Ease of manufacture
If the shielding member opening is made rectangular to hide circuit sections, then manufacturing is simplified, but image quality for non-rectangular displays deteriorates
Solution Approach 1:
Rather than making the entire shielding member complex, only the opening's peripheral edge is designed to locally conform to the display area's outer peripheral shape. This localized complexity achieves the necessary image quality improvement while keeping the overall shielding member structure relatively simple and manufacturable
Solution Approach 2:
Instead of designing the display area to fit a standard rectangular opening, the invention inverts the approach by designing the opening shape to fit the specific non-rectangular display area. This inversion allows the shielding member to be manufactured with a custom opening that precisely matches the display area geometry, improving image quality without requiring overly complex manufacturing processes

AI summary
A display system includes a display and a shielding member. The display has a display screen to display an image thereon. The shielding member has an opening, through which light emerging from the display screen passes. The shielding member defines a shape of the light emerging from the display screen. The display screen has a non-rectangular display area to display the image thereon. At least one peripheral edge of the opening defines a shape that conforms to an outer peripheral shape of the display area.
