Display Panel Transfer Method with Impact Preventing Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thin display panels are prone to cracking during transportation due to collisions with the interior of trays or jigs, as they lack adequate protection against impacts.
Innovation Solution
A display panel transfer method that includes a coating layer and an impact preventing layer, where the impact preventing layer covers the rear surface of the coating layer and has a larger area than the display panel, providing additional protection against impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a thin display panel is transported in a tray or jig, then transportation is enabled, but cracks may occur due to collision with the inside of the tray or jig
Solution Approach 1:
The patent applies beforehand cushioning by providing an impact preventing layer on the rear surface of the display panel before transportation. This layer has an area larger than the display panel area to ensure complete coverage, creating a protective cushion that absorbs impact forces during transportation and prevents cracks when the panel collides with the tray or jig interior.
2Reliability
If an impact preventing layer with area larger than the display panel is provided, then crack prevention is improved, but device complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the area parameter of the impact preventing layer, making it larger than the display panel area. This parameter change ensures that the protective layer extends beyond the panel boundaries, providing comprehensive protection while maintaining a simple single-layer structure that does not significantly increase device complexity.

AI summary
A display panel transfer method includes providing a coating layer onto a rear surface of a display panel and providing an impact preventing layer onto a rear surface of the coating layer, wherein an area of the display panel is smaller than an area of the impact preventing layer and is larger than an area of the coating layer when viewed on a plane.
