Snap-Fit Plasma Display Module to Reduce Cover Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plasma displays suffer from poor pressure resistance due to deformation of the upper and lower cover plates under external forces, necessitating an improvement in structural strength and overall resistance.
Innovation Solution
A snap-fit plasma display module design featuring a plasma display cavity filled with particles, a filter layer with snap-fit structures and conductive dielectric layers, and a plasma isolation structure that enhances structural integrity by embedding the isolation structure into clamping grooves, using a transparent resin layer to maintain a flat surface and reduce plasma movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a glass substrate with filter layer and ITO layer is used to form the plasma display structure, then the display can achieve basic functionality, but the upper cover plate and lower cover plate deform under external force resulting in poor pressure resistance
Solution Approach 1:
The plasma display structure is divided into multiple functional layers including first substrate, second substrate, filter layer, pixel electrode layer, plasma isolation structure, and cover plates. Each layer is segmented to perform specific functions, with the plasma isolation structure specifically designed to prevent plasma leakage and the cover plates to provide structural support. This segmentation allows each component to be optimized for its specific function while collectively improving pressure resistance.
Solution Approach 2:
The plasma isolation structure is embedded within the plasma display cavity, nesting between the first substrate and second substrate. The cover plates are positioned to enclose the plasma display cavity, creating a nested arrangement where inner structures are contained within outer protective layers. This nesting provides multiple levels of structural support and protection against external forces.
2Strength
If the plasma display cavity is filled with plasma particles and covered by cover plates, then the display achieves plasma containment, but the overall structural strength is insufficient leading to deformation under external force
Solution Approach 1:
The plasma display employs a composite structure combining glass substrates, metal electrode layers, plastic filter layers, and resin sealing materials. The first substrate and second substrate are made of glass providing structural strength, while the filter layer and sealing structures use plastic and resin materials for flexibility and sealing. This composite material approach allows each material to contribute its specific properties to the overall structural strength while maintaining functionality.
Solution Approach 2:
The plasma isolation structure is pre-formed on the pixel electrode layer before assembling the cover plates. The cover plates are pre-positioned and sealed to the first substrate using sealing structures. This preliminary action ensures that the plasma containment structure is established before final assembly, allowing the plasma particles to be contained within the formed cavity while the cover plates provide structural support against external forces.
