Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges with viewing angle control and luminance characteristics, particularly in preventing the collapse of light blocking films and ensuring efficient manufacturing processes.
Innovation Solution
A display device is designed with a light control layer that includes a plurality of light blocking films spaced apart, a light transmitting film, and bridges connecting the light blocking films, which helps in improving viewing angle control and preventing film collapse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If light blocking films are disposed spaced apart to improve viewing angle control, then viewing angle characteristics are improved, but the light blocking films may collapse during manufacturing
Solution Approach 1:
A bridge structure is introduced as an intermediary element between the light blocking films. The bridge physically connects adjacent light blocking films, providing mechanical support and preventing collapse during manufacturing while maintaining the spaced-apart configuration needed for viewing angle control.
Solution Approach 2:
The light control layer is segmented into multiple functional components: light blocking films for viewing angle control, bridges for structural support, and light transmitting films for light passage. This segmentation allows each component to perform its specific function without interfering with others.
2Manufacturing precision
If multiple light blocking films are added to improve viewing angle control, then viewing angle characteristics are improved, but device complexity increases
Solution Approach 1:
Multiple functions are merged into a single light control layer: light blocking films for viewing angle control, bridges for structural support, and light transmitting films for light passage. This integration reduces overall device complexity compared to having separate components for each function.
Solution Approach 2:
The light control layer serves multiple purposes simultaneously: controlling viewing angles through spaced light blocking films, providing structural stability through bridges, and allowing light transmission through the light transmitting film. This multi-functionality reduces the need for additional separate components.
3Reliability
If light blocking films are made taller to prevent collapse, then film stability is improved, but manufacturing precision deteriorates due to collapse during processing
Solution Approach 1:
The bridge structure is formed beforehand to provide preliminary mechanical support to the light blocking films. This preliminary action prevents collapse during subsequent manufacturing processes, allowing tall light blocking films to be formed with high precision without deformation.
Solution Approach 2:
The bridge acts as a cushioning support structure that prevents mechanical failure of the light blocking films during manufacturing. By providing this protective support in advance, the light blocking films can maintain their intended dimensions and positioning throughout the manufacturing process.
