Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in display panel technology is to enhance the arrangement of components within a display area while maintaining or increasing the display area's size, while also ensuring efficient integration of various functions without compromising the structural integrity and performance.
Innovation Solution
The display panel incorporates a substrate with distinct areas, featuring a multi-layered film structure in the non-display areas that includes an inorganic material layer with a step elevation, grooves separating organic material layers, and a thin-film transistor configuration, along with organic and inorganic insulating layers to support the pixel electrode and encapsulation, allowing for efficient component placement and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are arranged in the display area to add various functions, then functionality is improved, but the display area size is reduced
Solution Approach 1:
The display panel is divided into distinct functional zones: a display area for visual output and a non-display area for component placement. This segmentation allows components to be arranged in the non-display area, adding functionality without reducing the display area size.
Solution Approach 2:
The patent utilizes the third dimension by creating a multi-layered film structure with steps and grooves in the non-display area. This vertical dimensionality allows for complex component integration and encapsulation without occupying additional horizontal display area.
2Adaptability or versatility
If a multi-layered film structure with steps is created in the non-display area, then component integration is improved, but manufacturing complexity increases
Solution Approach 1:
The multi-layered film structure with steps is formed preliminarily in the non-display area before final component assembly. This preliminary structuring simplifies subsequent component integration by providing pre-defined mounting locations and encapsulation pathways.
Solution Approach 2:
The patent employs a nested multi-layered film structure where layers are stacked and interconnected with steps and grooves. This nesting approach allows compact component integration within the non-display area while maintaining a systematic manufacturing process.
3Reliability
If grooves are provided in the multi-layered film to separate organic material layers, then structural reliability is improved, but manufacturing precision requirements increase
Solution Approach 1:
Grooves are selectively formed only in specific regions of the multi-layered film where separation is required, rather than uniformly throughout. This localized approach maintains structural reliability at critical interfaces while reducing overall manufacturing precision requirements.
Solution Approach 2:
The grooves act as intermediary structures that facilitate the separation and isolation of organic material layers. By providing these intermediate separation zones, the patent achieves reliable layer isolation without requiring extremely precise direct interfacing between layers.
