Display Window Support Film for Simpler Antireflective Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in manufacturing processability, particularly in integrating components like windows and anti-reflective layers, which can lead to increased costs and complexity.
Innovation Solution
A display device design featuring a display panel with an anti-reflective layer, a support film with a frame shape, and a coated window, where the support film and light-shielding pattern are positioned to cover the edge portions, simplifying the manufacturing process and reducing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional manufacturing process is used for integrating windows and anti-reflective layers, then the manufacturing processability is poor and costs are high, but the optical characteristics and component protection are maintained
Solution Approach 1:
The support film and light-shielding pattern are merged into a single integrated component. The support film serves dual functions: providing structural support for the coated window and acting as a light-shielding layer when combined with the light-shielding pattern. This integration reduces the number of separate components and simplifies the manufacturing process while maintaining the necessary optical characteristics and component protection
2Productivity
If material usage is minimized to reduce costs, then manufacturing efficiency improves, but component protection and optical characteristics may be compromised
Solution Approach 1:
The light-shielding pattern is applied selectively only to the edge portions of the support film where it is most needed for component protection, rather than covering the entire support film. This localized approach minimizes material usage and reduces manufacturing complexity while maintaining adequate protection for the internal components. The optical characteristics are preserved by limiting the light-shielding material to areas where it will not interfere with light transmission to the display panel

AI summary
A display device includes a display panel, an anti-reflective layer disposed on the display panel, a support film having a frame shape when viewed on a plane, and disposed on an edge portion of the anti-reflective layer, and a coated window disposed on an upper surface of the support film and an upper surface of the anti-reflective layer.
