Touch Wire Layering in Display Panels for Narrow Bezel Layouts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch display panels require a wide non-display region for touch wire wiring, affecting the screen-to-body ratio and preventing the achievement of a narrow bezel design.
Innovation Solution
The display panel incorporates touch wires into the display region, with at least two first touch wires disposed in different films and layered wiring, reducing the non-display region's wiring area and increasing the screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If touch wires are led through the non-display region, then sufficient wiring space is provided for touch wires, but the non-display region becomes wide, affecting the screen-to-body ratio
Solution Approach 1:
The patent transitions touch wire routing from a two-dimensional planar layout in the non-display region to a three-dimensional stacked configuration within the display region. Multiple touch wires are arranged in different films (first touch wire in first film, second touch wire in second film), utilizing the vertical dimension to reduce lateral wiring space requirements and minimize the non-display region width.
2Area of stationary object
If touch wires are disposed in the display region in different films, then the non-display region width is reduced, but wiring complexity increases
Solution Approach 1:
The patent segments the wiring structure into multiple independent films, with each film containing specific touch wires. The first touch wire is disposed in the first film and the second touch wire is disposed in the second film, allowing independent routing and connection of each touch wire to its corresponding touch electrode block, thereby managing complexity through modular organization.
Solution Approach 2:
The patent employs a universal film structure where multiple films are stacked to accommodate different touch wires. Each film serves as a standardized layer that can contain touch wires and connect to touch electrode blocks, providing a multi-functional platform that handles both wiring and structural requirements within the display region.
