Display Spacing Member Adhesion via Intersecting Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display media often experience insufficient adhesion strength between the spacing member and the display substrate, which can lead to structural instability and affect the performance of the display device.
Innovation Solution
A display medium configuration featuring a spacing member with a first portion projecting in an intersecting direction, where a holding layer is provided on the display substrate to fill the gap between the substrate and the spacing member's end face, embedding the spacing member's first portion and enhancing adhesion, while also serving as a surface layer to suppress particle adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional spacing member configuration is used without extended portions, then the device complexity is low, but the adhesion strength between the spacing member and display substrate is insufficient
Solution Approach 1:
The spacing member is designed with a first portion that extends in a direction intersecting the facing direction of the substrates, adding a dimensional component that improves adhesion without significantly complicating the overall device structure. This extended portion projects toward the display substrate, creating a larger contact area and mechanical interlocking when embedded in the holding layer.
Solution Approach 2:
The spacing member is divided into distinct functional portions: a body portion that maintains the gap between substrates and a first portion that extends in an intersecting direction to provide enhanced adhesion. This segmentation allows each portion to optimize its specific function while keeping the overall design manageable.
2Strength
If the spacing member contact area with display substrate is increased, then the adhesion strength improves, but the manufacturing precision requirements increase
Solution Approach 1:
A holding layer is introduced as an intermediary between the spacing member and the display substrate. This holding layer fills the gap between the substrate and the spacing member's end face, and embeds the first portion, providing a compliant interface that accommodates manufacturing variations while ensuring strong adhesion through the adhesive properties of the holding layer material.
3Stability of the object's composition
If a holding layer is added to embed the spacing member, then the adhesion strength and structural integrity improve, but the device complexity increases
Solution Approach 1:
The holding layer serves multiple functions simultaneously: it fills the gap between the display substrate and spacing member, embeds the first portion of the spacing member for mechanical retention, provides adhesive bonding, and acts as a surface layer to suppress particle adhesion. This multi-functionality justifies the additional layer by consolidating several requirements into a single structural element.

AI summary
A display medium includes: a pair of substrates; a spacing member that maintain a gap between the pair of substrates and has a first portion projecting in an intersecting direction, the intersecting direction intersecting a direction in which the pair of substrates face each other; and a holding layer that is provided on at least one of the pair of substrates such that the holding layer fills a space between the at least one of the pair of substrates and an end face of the spacing member, the holding layer covers the first portion from the end face of the spacing member, and the holding layer holds an end part of the spacing member in the direction in which the pair of substrates face each other.
