Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floating image generation devices require backlights to display images, leading to images vanishing when lights are extinguished, which limits user experience.
Innovation Solution
A floating image generation device comprising a light source, first and second image forming units, and a transflective layer that allows for the generation of floating images using a first light from the light source and flat images using ambient light reflected by a transflective layer, enabling image display without continuous backlighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If back lights are used to display floating images, then image visibility is improved, but energy consumption increases and images vanish when lights are extinguished
Solution Approach 1:
The transflective layer serves dual functions: it transmits light from the backlight unit to form floating images during active display, and reflects ambient light to form flat images when the backlight is off. This multi-functionality allows the device to maintain image display capability across different power states, reducing energy consumption while preserving visibility options.
Solution Approach 2:
When the backlight is extinguished, the system uses ambient light reflected by the transflective layer to generate flat images without requiring additional power input. The device serves itself by utilizing environmental light resources, eliminating the need for continuous backlight operation and reducing energy consumption.
2Illumination intensity
If back lights are continuously on to maintain image visibility, then image display capability is improved, but device complexity and heat generation increase
Solution Approach 1:
The transflective layer enables the display system to operate in two modes using the same optical path: transmitting backlight for floating images and reflecting ambient light for flat images. This eliminates the need for separate display systems for different modes, reducing device complexity.
3Adaptability or versatility
If conventional floating image generation is used, then floating image capability is achieved, but adaptability to different lighting conditions is limited
Solution Approach 1:
The display device can adapt to different lighting conditions by switching between two image generation modes: using transmitted backlight for floating images in various lighting environments, and using reflected ambient light for flat images when backlight is off. This enhances versatility across different operational scenarios.
Solution Approach 2:
In dark conditions or when power is reduced, the system automatically utilizes ambient light reflection through the transflective layer to maintain image display capability without requiring additional power input, adapting to the available lighting environment.
