Flexible Conductive Layer for Narrow Border Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with ink layers, conductive silver pillars, conductive films, and water-blocking films are not bendable and have minimum distance requirements that result in wide borders, making it impossible to design display devices with narrow borders.
Innovation Solution
A display device with a conductive material layer that extends from the display medium layer to the driving substrate, reducing border width by eliminating the need for conductive silver pillars and using a wet process to form a conductive and water-blocking material layer without a base, allowing for flexible and narrow border designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If conductive silver pillars and water-blocking films with bases are used, then conductivity and water-blocking properties are achieved, but the border width increases and the structure becomes rigid and non-bendable
Solution Approach 1:
The patent replaces rigid conductive silver pillars and water-blocking films with a flexible conductive material layer that has no base. This thin film structure allows the display device to be bendable while maintaining conductivity and water-blocking properties, and significantly reduces the border width.
Solution Approach 2:
The patent extracts and eliminates the base structure from the conductive material layer, allowing it to be directly formed on the display medium layer. This removal of the base enables the material layer to be flexible and bendable, while also reducing the overall border width of the display device.
2Length of stationary object
If minimum distance requirements of 5mm between water-blocking paste and conductive silver pillar are maintained, then manufacturing reliability is ensured, but the border width increases
Solution Approach 1:
The patent merges the conductive material layer and water-blocking material layer into a single integrated conductive material layer that provides both conductivity and water-blocking properties. This eliminates the need for separate components and minimum distance requirements between them, allowing the border width to be reduced while maintaining manufacturing reliability.
3Adaptability or versatility
If conductive films and water-blocking films with bases are used, then electrical connection and water-blocking functions are achieved, but the structure cannot be bent to fit free-form surfaces
Solution Approach 1:
The patent uses a flexible conductive material layer without a base that can be bent and conform to free-form surfaces such as spherical surfaces. This thin film structure maintains electrical connection and water-blocking functions while enabling the display device to be adapted to various curved geometries.
