Bending Area Wire Routing for Display Terminal Width Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in minimizing the width of terminal parts and improving response performance due to increased power consumption and complex wiring configurations, particularly in achieving efficient signal transmission across bending areas.
Innovation Solution
The display apparatus incorporates a substrate with a bending portion, an inorganic insulating layer, and an organic material layer, where wire parts extend through the bending area, connected via a connection wire part, allowing for symmetric and efficient signal transmission between drivers, reducing the size of the terminal part and minimizing signal delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wire parts are extended through the bending area to connect drivers, then signal transmission efficiency is improved, but the terminal part width increases
Solution Approach 1:
The patent transitions from planar wire routing to three-dimensional routing by extending wire parts through the bending area in the thickness direction. This allows signals to bypass the narrow terminal part region while maintaining efficient transmission paths, effectively resolving the contradiction between transmission efficiency and terminal width constraints.
Solution Approach 2:
The wire connection structure is divided into multiple segments: wire parts extending from the bending area, connection wire parts in the non-display area, and terminal connections. This segmentation allows each component to be optimized independently, enabling efficient signal transmission while keeping the terminal part compact.
2Measurement precision
If the number of thin-film transistors is increased to control emission precisely, then emission control accuracy is improved, but power consumption and device complexity increase
Solution Approach 1:
The patent implements multi-functionality by enabling each thin-film transistor to control multiple emission characteristics through the extended wire part connections. The wire parts transmit multiple signal types (scan signals, data signals, emission control signals) through shared pathways, allowing precise emission control with fewer transistors than traditional architectures.
