Solution Overview
Problem
Current transparent display devices face challenges in minimizing diffraction phenomena and improving transparency, leading to reduced clarity and readability due to external light interference and manufacturing processes that generate greenhouse gases.
Innovation Solution
A transparent display panel design featuring a transmissive area with a first optical pattern at its center and second optical patterns at the border, optimized to enhance light concentration and reduce diffraction, along with an encapsulation layer and optical insulating layer to improve transparency and readability, while also incorporating a black matrix to reduce manufacturing-related greenhouse gas emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transmissive area is provided to allow external light to pass through, then transparency and visibility of background scenes are improved, but diffraction phenomenon and haze increase reducing clarity and readability
Solution Approach 1:
The transmissive area is divided into multiple sub-areas, each containing a lens structure. This segmentation allows light to be focused through multiple controlled points rather than passing through a single large opening, reducing diffraction effects while maintaining transparency.
Solution Approach 2:
Lens structures with curved surfaces are introduced in the transmissive area. These curved surfaces refract and focus external light, reducing diffraction phenomenon and haze while improving clarity and readability through the transparent display panel.
2Illumination intensity
If a transmissive area is provided to allow external light to pass through, then transparency and visibility of background scenes are improved, but external light interference increases reducing readability
Solution Approach 1:
The transmissive area is divided into multiple sub-areas with lens structures that focus light to specific regions. This segmentation controls light paths and reduces unwanted external light interference in the display area while maintaining transparency for background viewing.
Solution Approach 2:
Lens structures with curved surfaces are introduced in the transmissive area. These curved surfaces refract and focus external light, reducing diffraction phenomenon and haze while improving clarity and readability through the transparent display panel.
3Ease of manufacture
If manufacturing processes are used to produce display devices, then display devices can be manufactured, but greenhouse gas emissions increase
Solution Approach 1:
The patent extends the lifespan of display devices through improved optical structures (lens patterns in transmissive areas), which reduces the frequency of manufacturing and replacement. This parameter change in device durability indirectly reduces greenhouse gas emissions from manufacturing processes.
