Transparent Display Substrate Layout to Minimize Diffraction Distortion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic devices with transparent display substrates suffer from image distortion due to complex diffraction patterns when external light passes through, caused by the complex structure of sub-pixel groups, which affects the performance of photosensitive components like cameras.
Innovation Solution
A transparent display substrate design where each pixel unit includes sub-pixel groups with adjacent sub-pixels electrically connected by a first connecting portion and non-adjacent sub-pixels connected by a second connecting portion, both located in the same layer, reducing the number of pixel circuits and minimizing diffraction and superposition, thereby enhancing image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex structure of sub-pixel groups is used in transparent display substrate, then display functionality is achieved, but diffraction and superposition occur causing image distortion
Solution Approach 1:
The patent extracts and removes the pixel circuit structure from the transparent display substrate. By implementing the connecting portions directly in the transparent substrate layer without separate pixel circuits, the design eliminates the complex structure that causes diffraction and superposition, thereby removing the source of image distortion while preserving display functionality.
Solution Approach 2:
The patent merges the connecting portions with the transparent substrate structure itself. The first and second connecting portions are integrated directly into the transparent display substrate, combining the electrical connection function with the transparent structural layer, thus eliminating separate circuit elements that would cause diffraction.
2Ease of operation
If multiple pixel circuits are used to drive sub-pixels, then each sub-pixel can be controlled, but the number of pixel circuits increases causing more diffraction
Solution Approach 1:
The patent implements a universal connecting structure where the first and second connecting portions serve multiple functions simultaneously. These connecting portions provide electrical connections for multiple sub-pixels across different sub-pixel groups while maintaining transparency, eliminating the need for separate dedicated pixel circuits for each sub-pixel group.
Solution Approach 2:
The patent combines the electrical connection function with the transparent substrate structure. The connecting portions are integrated into the transparent display substrate itself, merging the circuit function with the structural layer, thereby reducing the number of separate pixel circuits needed while maintaining sub-pixel control capability.
3Reliability
If connecting portions are placed in different layers, then electrical connections can be made, but manufacturing process complexity increases
Solution Approach 1:
The patent merges both the first and second connecting portions into the same layer of the transparent display substrate. This integration allows electrical connections to be made within a single manufacturing step without requiring multiple layer deposition or alignment processes, thereby simplifying the manufacturing process while ensuring reliable electrical connections.
Solution Approach 2:
The patent designs the connecting portions to be formed in advance during the same manufacturing step. By planning the connecting portions to be created simultaneously in one procedure, the design eliminates the need for subsequent alignment and connection steps, reducing manufacturing complexity while ensuring connection reliability.
