Integrated Display Panel Full-Lamination Gap Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-size infrared touch screens, the separate structure of surface glass and liquid crystal panel creates a gap that affects touching and viewing experiences and leads to rework and assembly failures during the assembly process.
Innovation Solution
A display panel design that integrates the surface glass and liquid crystal panel through a full-lamination process, using a front frame component to fix the display module to the backlight module, eliminating the gap between them and improving assembly efficiency and display effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surface glass and liquid crystal panel are kept as separate structures, then the assembly process allows for independent handling of each component, but a gap is formed between them that affects touching and viewing experiences and leads to rework and assembly failures
Solution Approach 1:
The patent merges the surface glass and liquid crystal panel into a single integrated structure through a full-lamination process, eliminating the gap between them. This combining approach resolves the technical contradiction by achieving both structural integration (improving reliability) while managing the complexity through a standardized lamination process.
2Manufacturing precision
If the surface glass and liquid crystal panel are integrated through full lamination, then the gap is eliminated improving touching and viewing experiences, but the assembly process becomes more complex requiring precise alignment and bonding
Solution Approach 1:
The patent applies preliminary action by performing the lamination process during the initial assembly stage, ensuring precise alignment and bonding between the surface glass and liquid crystal panel before subsequent assembly steps. This preliminary integration simplifies later manufacturing steps while achieving the required precision.
3Object-generated harmful factors
If the surface glass and liquid crystal panel are repeatedly cleaned during assembly, then contamination is removed, but rework is required and assembly failures increase
Solution Approach 1:
The patent implements preliminary cleaning and protection measures before the lamination process, ensuring that the surface glass and liquid crystal panel are free from contamination prior to integration. This preliminary action eliminates the need for repeated cleaning and rework during assembly, thereby improving productivity while maintaining contamination control.
