Transparent Film Coating Window for Display Panel Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require a lamination process to attach a glass window, which is costly and complex, and does not effectively protect the display panel from external impacts.
Innovation Solution
A display device is manufactured using a transparent film to create a coating window, where the transparent film is disposed under the coating window and serves as a base layer for the cured resin material, simplifying the manufacturing process and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a glass window is attached through a lamination process, then the display panel is protected from external impacts, but the manufacturing process becomes costly and complex
Solution Approach 1:
The patent combines the window layer and the lower polarizer into a single integrated structure. The window layer serves dual functions: protecting the display panel from external impacts and acting as the lower polarizer. This eliminates the need for separate lamination of a glass window and reduces the number of manufacturing steps, thereby simplifying the manufacturing process while maintaining impact protection
Solution Approach 2:
The window layer is designed to perform multiple functions simultaneously: it provides mechanical protection against external impacts, acts as the lower polarizer for the liquid crystal display, and serves as a structural component of the display assembly. This multi-functionality reduces the overall complexity of the manufacturing process by eliminating the need for separate components and assembly steps
2Reliability
If a glass window is attached through a lamination process, then the display panel is protected from external impacts, but the manufacturing cost increases
Solution Approach 1:
The patent merges the window layer and lower polarizer into one integrated component, eliminating the need for separate procurement, handling, and lamination processes. This consolidation reduces material costs, manufacturing overhead, and production time, thereby lowering the overall manufacturing cost while maintaining impact protection functionality
Solution Approach 2:
By designing the window layer to serve as both the protective element and the lower polarizer, the patent eliminates redundant components and assembly steps. This multi-functional design reduces material costs, simplifies the supply chain, and decreases manufacturing complexity, leading to lower overall production costs while ensuring impact protection
3Ease of manufacture
If a transparent film is used to manufacture a coating window, then the manufacturing process is simplified and costs are reduced, but the protection from external impacts may be compromised
Solution Approach 1:
The patent combines the window layer and lower polarizer into a single integrated structure made from transparent film material. This integration simplifies the manufacturing process by reducing the number of components and assembly steps while the transparent film maintains sufficient mechanical strength to provide impact protection, thus resolving the contradiction between manufacturing simplicity and protection reliability
Solution Approach 2:
The patent utilizes transparent film material with appropriate thickness and mechanical properties to achieve both manufacturing simplicity and impact protection. By carefully selecting and optimizing the material parameters of the transparent film, the patent ensures that the simplified manufacturing process does not compromise the protective function against external impacts
