Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch display panels face issues with line breaks in conductive bridges due to large slopes and truncated regions, leading to reduced reliability and performance in touch control structures.
Innovation Solution
The implementation of displaced conductive bridges and capacitance compensating structures in a flexible multi-layer on-cell touch (FMLOC) technology, where conductive bridges are positioned away from high-slope areas and truncated regions, and capacitance compensating plates are used to maintain effective touch control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conductive bridges are arranged in a regular array pattern, then manufacturing precision is improved, but reliability deteriorates due to line breaks in high-slope and truncated regions
Solution Approach 1:
The patent applies local quality by differentiating the arrangement of conductive bridges based on local geometric characteristics. In high-slope and truncated regions, conductive bridges are displaced from the regular array pattern to avoid line breaks, while in normal regions they maintain the regular array arrangement. This localized adjustment optimizes reliability without sacrificing overall manufacturing precision.
2Device complexity
If conductive bridges are positioned in high-slope regions to maintain array continuity, then device complexity is reduced, but manufacturing precision deteriorates due to line breaks
Solution Approach 1:
The patent segments the conductive bridge arrangement into two types: regular array bridges in normal regions and displaced bridges in high-slope/truncated regions. This segmentation allows each type to be optimized independently - regular bridges maintain manufacturing precision in suitable areas, while displaced bridges avoid line breaks in problematic areas, overall reducing device complexity.
