Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies for vehicles lack the flexibility and reliability to provide a seamless and large display surface with minimal visibility of seams between pixel regions, especially in curved surfaces, which limits their ability to effectively display information from multiple cameras and sensors.
Innovation Solution
A display apparatus with a curved surface is created by overlapping and connecting multiple pixel regions with a wiring layer, using flexible substrates and electrodes to minimize seam visibility, and employing a structure where adjacent pixel regions have a small gap, allowing for a large, seamless display area with improved design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple pixel regions are combined to form a large display surface, then the display area is increased, but the visibility of seams between pixel regions increases
Solution Approach 1:
The patent transitions from planar pixel region arrangement to three-dimensional curved surface arrangement. By forming pixel regions on a curved surface with specific radius of curvature, the display apparatus achieves large display area while the curvature naturally masks seam visibility through optical effects and continuous surface geometry.
Solution Approach 2:
The patent applies curved surface geometry to the display apparatus, where pixel regions are arranged on a surface with a predetermined radius of curvature. This curvature allows the display to maintain large area while reducing seam visibility, as the continuous curved surface obscures the boundaries between individual pixel regions.
2Object-generated harmful factors
If pixel regions are arranged with small gaps to reduce seam visibility, then seam visibility is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent specifies a predetermined radius of curvature parameter for the curved surface on which pixel regions are arranged. By controlling this geometric parameter, the patent achieves optimal balance between seam visibility reduction and manufacturing feasibility, as the curvature provides natural alignment guidance while maintaining acceptable tolerance ranges.
3Object-generated harmful factors
If a curved surface structure is used to reduce seam visibility, then seam visibility is reduced, but the device complexity increases
Solution Approach 1:
The patent employs a curved surface with predetermined radius of curvature as the fundamental structural element. This curvature serves multiple functions simultaneously: it reduces seam visibility, provides structural integrity, and guides pixel region arrangement, thereby achieving harm reduction without proportionally increasing complexity.
4Area of stationary object
If multiple flexible substrates are used to create a large curved display, then the display area and design flexibility are increased, but the number of components and assembly complexity increase
Solution Approach 1:
The patent divides the large curved display into multiple pixel regions formed on separate flexible substrates. Each substrate can be manufactured and tested independently, then assembled into the final curved display configuration. This segmentation enables large area achievement while maintaining manufacturing and assembly feasibility through modular construction.
