Detour Data Lines for Display Peripheral Area Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses face challenges in minimizing the non-display peripheral area, which affects portability and aesthetics, particularly due to the need for extensive data line connections that increase the width of this area.
Innovation Solution
The display apparatus incorporates detour data lines that connect data lines in the display area to the pad portion in the peripheral area through contact holes, allowing for a reduced width of the non-display area by eliminating the need for spider lines and enabling a folded design with a driver area on the back surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If data lines are extended directly from the display area to the pad portion in the peripheral area, then electrical connection is achieved, but the width of the non-display peripheral area increases
Solution Approach 1:
The patent introduces detour data lines that extend data line connections into the display area and utilize the folding area (third dimension when folded) to route signals to the pad portion, rather than extending lines directly across the peripheral area. This dimensional approach allows the non-display area width to be minimized while maintaining electrical connectivity through the folded structure.
Solution Approach 2:
The detour data lines act as intermediary elements that connect the data lines in the display area to the pad portion in the peripheral area through contact holes. These intermediary lines route signals through the folding area, enabling connection without requiring direct extension across the peripheral area, thus resolving the contradiction between connection reliability and peripheral area width.
2Ease of operation
If spider lines are used to connect data lines to the pad portion, then electrical connection is achieved, but the non-display area width increases and portability is reduced
Solution Approach 1:
The patent extracts and eliminates the spider line structure from the design. Instead of using radial spider lines to connect data lines to the pad portion, the invention uses detour data lines that route connections through the folding area, removing the need for extensive spider line infrastructure and thereby reducing the non-display area width and improving portability.
Solution Approach 2:
By utilizing the folding area as an additional dimensional space for routing data line connections, the patent eliminates the need for spider lines that would otherwise occupy lateral space in the non-display area. This dimensional routing approach directly reduces the width of the non-display peripheral area while maintaining all necessary electrical connections.
3Area of stationary object
If the peripheral area is minimized for better portability, then device compactness is improved, but data line connection complexity increases
Solution Approach 1:
The patent segments the data line connection path into distinct sections: data lines in the display area, detour data lines in the folding area, and connections through contact holes to the pad portion. This segmentation allows each section to be optimized independently, reducing the overall peripheral area width while managing connection complexity through structured division of the connection pathway.
