Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interference between luminescent units in OLED display panels affects the full-color display effect due to light emission from one unit interfering with others.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If light-isolating members are disposed between luminescent units, then light interference between luminescent units is prevented, but device complexity increases
Solution Approach 1:
The patent introduces light-isolating members as intermediary elements positioned between adjacent luminescent units. These members act as mediators that block light from one luminescent unit from reaching adjacent units, thereby preventing color contamination and improving display quality without requiring fundamental changes to the OLED structure
Solution Approach 2:
The patent segments the display panel by introducing light-isolating members that divide the continuous structure into isolated luminescent units. This segmentation prevents light from spreading between units, effectively addressing the interference problem while maintaining a relatively simple overall structure
2Object-affected harmful factors
If light-isolating members are protrusively disposed between luminescent units, then light isolation effectiveness is improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent transitions from planar light isolation to three-dimensional isolation by protrusively disposing light-isolating members vertically between luminescent units. This dimensional change creates physical barriers that more effectively block light paths, improving isolation effectiveness while the protrusive structure provides clear manufacturing references
3Object-affected harmful factors
If opaque polymer composite material or black matrix material is used for light-isolating members, then light blocking capability is improved, but manufacturing process complexity increases
Solution Approach 1:
The patent changes the optical parameter (transparency) of the light-isolating members by selecting opaque materials such as opaque polymer composite materials or black matrix materials. This parameter change ensures effective light blocking while these materials are chosen specifically for their compatibility with existing OLED manufacturing processes
