A flexible display module with a dual-layer optical control system comprising a first and second light control layer, each with specific light-shielding and transmission properties, to control light angles and prevent projections on windshields, combined with a stress buffer layer for durability and a texture coating for visual integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display module is attached to the curved surface in the dashboard, then the display screen can be integrated into the dashboard surface, but the displayed image forms a projection on the windshield, interfering with the sight of the driver and passengers
Solution Approach 1:
The optical control layer is divided into multiple light control layers, each with different dimming rates and light control characteristics. This segmentation allows precise control of light transmission at different angles, enabling the display to adapt to the curved dashboard surface while preventing projection on the windshield by selectively blocking light at specific angles.
Solution Approach 2:
Different regions of the optical control layer have different light control properties. The light control layers are configured with varying dimming rates to control light transmission in different directions - allowing light transmission toward the viewer while blocking light that would project onto the windshield, thus creating local quality variations to solve the projection problem.
2Adaptability or versatility
If a planar display screen is embedded in the interior panel of the dashboard, then the display can be integrated into the dashboard, but the size and installation angle are greatly limited due to dashboard space constraints
Solution Approach 1:
The display module is designed with a flexible curved surface that can conform to the dashboard's curved geometry. This curvature allows the display to wrap around the dashboard surface, effectively utilizing the available space and enabling larger display areas without being constrained by the dashboard's physical dimensions, thus resolving the contradiction between integration and size.
Solution Approach 2:
The flexible display module can dynamically adjust its curvature and conform to different dashboard surfaces. This dynamic adaptability allows the display to optimize its size and shape based on the specific installation environment, enabling larger display areas while maintaining proper integration with the dashboard structure.
3Loss of information
If multiple display screens are added to the automobile, then information presentation capability is improved, but potential safety hazards increase due to excessive screens
Solution Approach 1:
Multiple display functions are merged into a single flexible curved display module. By integrating multiple information presentation areas into one unified curved surface, the system provides comprehensive information display capability while occupying less space and reducing the number of separate screen components, thereby maintaining safety by avoiding excessive screens.
Solution Approach 2:
The flexible curved display module serves multiple functions simultaneously - it can display different types of information (navigation, entertainment, vehicle status) across its curved surface, replacing multiple specialized screens with one universal display system that provides all necessary information without creating safety hazards from excessive screens.
