Solution Overview
Problem
Existing display panels face challenges in efficiently integrating various components and functions within a limited display area while maintaining low power consumption and thin, lightweight designs.
Innovation Solution
A display panel design featuring a substrate with distinct areas, including a first area for components, a second area with a laminated structure comprising a pixel electrode, opposite electrode, intermediate layer, and organic material layers, and a third area with grooves that separate the organic material layers from the opposite electrode, enhancing component integration and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components are arranged in the display area to add various functions, then functional capabilities are enhanced, but display area efficiency is compromised
Solution Approach 1:
The patent utilizes the third dimension by creating a multi-layered film structure with different elevation levels. The first step structure provides a raised platform that allows additional components to be positioned vertically above the substrate plane, effectively adding functional capabilities without occupying horizontal display area space.
Solution Approach 2:
The display panel is divided into distinct functional areas: a first area for display elements and a second area for additional functions. This spatial segmentation allows the display area to maintain its efficiency while the second area provides dedicated space for enhanced functionality through the multi-layered film structure.
2Productivity
If a multi-layered film structure with steps is used to integrate components, then space utilization is optimized, but manufacturing complexity increases
Solution Approach 1:
The multi-layered film structure with the first step is formed preliminarily before positioning additional components. This preliminary structuring creates predetermined elevation levels and positioning features that guide subsequent component placement, thereby optimizing space utilization while managing manufacturing complexity through a systematic sequence of operations.
