Curved Display Panel Shielding Member Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat panel displays struggle to achieve uniform display quality and curved contours, particularly in applications like in-car instrumental panels and amusement equipment, where diverse planar shapes are demanded, due to the need for unique pixel shapes and sizes that complicate image display.
Innovation Solution
Incorporating a shielding member with a curved planar shape that shields pixels to form a curved contour in the display region, allowing for uniform image display and the ability to display curved lines, while the pixels can maintain either the same or different shapes depending on production processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pixels are arranged to form a curved contour in the display region, then design flexibility and appearance are improved, but manufacturing complexity increases due to requiring unique pixel shapes and sizes
Solution Approach 1:
The display region is segmented into a curved contour shape using a shielding member, while the pixels themselves maintain their standard rectangular shapes and uniform sizes. This segmentation allows the curved display region to be achieved without complicating the pixel structure or arrangement patterns.
Solution Approach 2:
A shielding member is introduced as an intermediary element between the pixel array and the external environment. This shielding member with a curved planar shape defines the curved contour of the display region while allowing the pixels to maintain their standard configurations, thus simplifying the overall system complexity.
2Shape
If a curved contour is formed by arranging pixels in unique shapes, then the curved line display capability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The curved contour function is extracted from the pixels themselves and assigned to a separate shielding member. This extraction allows pixels to maintain their standard rectangular shapes with consistent manufacturing specifications, while the shielding member provides the desired curved contour shape.
Solution Approach 2:
Instead of creating unique pixel shapes to achieve curved contours, the patent uses a shielding member that copies or replicates the desired curved contour shape. This approach maintains uniform pixel manufacturing while achieving the curved display region through the shielding member's geometry.
3Ease of manufacture
If standard rectangular pixels are used in a curved display region, then manufacturing ease is improved, but the ability to display smooth curved lines in the contour is compromised
Solution Approach 1:
The shielding member serves as an intermediary that bridges the gap between standard rectangular pixels and the desired curved display region. It allows uniform pixels to be manufactured using standard processes while the shielding member's curved geometry enables smooth curved line display in the contour.
Solution Approach 2:
The curved contour is achieved by adding a dimensional aspect through the shielding member's planar shape rather than modifying the pixels themselves. This dimensional approach allows standard pixels to be arranged in a curved region, maintaining manufacturing ease while achieving curved line display capability.
