Display System with Micro-Louver Film and Mirror Array for Floating Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems fail to effectively present a three-dimensional appearance or floating images, which is desirable for aesthetic and functional reasons in various applications, such as automotive displays, where it can reduce driver recognition time and improve image clarity and privacy.
Innovation Solution
A display system comprising a display unit with a micro-louver film and a mirror array plate that emits light orthogonally and reflects it to create a floating viewing plane, with the micro-louver film controlling light dispersion to improve image quality and prevent stray light from reaching unintended areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If light is emitted directly from the display unit without control, then the display can be simple in structure, but light dispersion occurs causing reduced image clarity and increased stray light
Solution Approach 1:
A micro-louver film is introduced as an intermediary component between the display unit and the mirror array plate. This film controls light dispersion by allowing light to pass through only in specific directions, thereby improving image clarity and reducing stray light without requiring complex optical systems
Solution Approach 2:
The light control function is segmented into multiple components: the micro-louver film handles directional light control, while the mirror array plate handles light reflection and focusing. This segmentation allows each component to be optimized independently for its specific function
2Object-affected harmful factors
If the viewing angle is not limited, then more viewers can see the display, but privacy is reduced and stray light increases
Solution Approach 1:
The micro-louver film provides different light transmission properties in different directions. It allows light to pass through effectively in the intended viewing direction while blocking light in other directions, thereby providing privacy and reducing stray light without completely limiting viewing accessibility
3Manufacturing precision
If the mirror array plate is used without light dispersion control, then the floating image effect can be achieved, but image quality deteriorates due to light dispersion outside the viewing angle
Solution Approach 1:
The micro-louver film performs preliminary light direction control before light reaches the mirror array plate. By pre-aligning light rays within the appropriate viewing angle range, the film ensures that subsequent reflection and focusing by the mirror array plate produces high-quality images with proper light concentration
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves a clear and aesthetically pleasing three-dimensional image presentation by focusing light at specific viewing planes, enhancing image clarity and reducing glare on vehicle windshields, while also providing privacy by limiting the viewing angle.
Implementation Method 1
The mirror array plate is operable to reflect the emitted light from the display unit along a viewing path, and toward a viewing location
Implementation Method 2
The mirror array plate is also operable to focus the reflected light at a viewing plane positioned between the mirror array plate and the viewing location
Implementation Method 3
The micro-louver film is operable to control light dispersion of the emitted light from the first display unit relative to the light path

AI summary
A display system includes at least one display unit, and a mirror array plate. The mirror array plate reflects light emitted from the display unit along a viewing path, and focuses the reflected light at a floating viewing plane positioned between the mirror array plate and a viewing location. The display system may include a micro-louver film disposed adjacent to the display unit that controls light dispersion of the emitted light from the display unit. The display system may include multiple display units arranged relative to the mirror array plate to present respective images on respective floating viewing planes to provide a three dimensional image.
