Engineering Contradiction Analysis
1Illumination intensity
If a light conversion layer is used to support display, then the display function is achieved, but part of light is transmitted in undesired directions affecting display effect
Solution Approach 1:
The patent introduces pixel light isolation structures that divide and segment the light paths between adjacent pixel units. These isolation structures create separate light transmission channels, preventing light from one pixel unit from leaking into adjacent pixel units, thus eliminating the harmful cross-talk while maintaining the overall display function.
Solution Approach 2:
The pixel light isolation structures serve as intermediary elements positioned between adjacent pixel units. These structures act as mediators that block or redirect light transmission in undesired directions, allowing the light conversion layer to maintain its display function while preventing harmful light leakage through the introduction of this intermediate isolation layer.
2Object-generated harmful factors
If pixel light isolation structure is arranged between adjacent pixel units, then light directionality is improved, but device complexity increases
Solution Approach 1:
The patent employs thin film-based pixel light isolation structures that can be integrated into the existing display layer structure. These thin film isolation layers provide effective light blocking without adding significant structural complexity or thickness, maintaining the flexibility and simplicity of the overall device while achieving the desired light isolation effect.
Solution Approach 2:
The patent optimizes the parameters of the pixel light isolation structures, such as their thickness, material composition, and geometric configuration, to achieve effective light isolation with minimal structural complexity. By carefully controlling these parameters, the isolation structures can be made compact and integrated seamlessly into the existing display architecture, reducing the overall device complexity.
