Solution Overview
Problem
Existing vehicular display devices face issues with imaging quality and occupant perception due to limitations in emitting near-infrared light with upper-bound visible wavelengths, leading to potential degradation in imaging quality and complex impressions for vehicle occupants.
Innovation Solution
A vehicular display device that incorporates a near-infrared irradiation portion and a disguise portion to emit near-infrared light including upper-bound visible wavelengths while disguising these wavelengths, preventing distinct recognition by occupants and maintaining imaging quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If near-infrared light including upper-bound visible wavelengths is emitted to the viewing side, then imaging quality is improved, but occupants may distinctly recognize the light causing complex impressions
Solution Approach 1:
The light emission is segmented into different wavelength components. The near-infrared light including upper-bound visible wavelengths is separated and treated differently from other wavelengths. A disguise portion selectively masks only the upper-bound visible wavelengths while allowing other wavelengths to pass through, thus maintaining imaging quality without causing complex impressions to occupants.
Solution Approach 2:
A disguise portion acts as an intermediary element between the near-infrared light source and the occupants. This intermediary selectively interacts with the light, disguising the upper-bound visible wavelengths to prevent distinct recognition by occupants while permitting the light to continue serving its imaging function.
2Illumination intensity
If visible light is emitted for display, then information visibility is improved, but imaging quality degrades due to interference with near-infrared imaging
Solution Approach 1:
Different regions of the display device have different optical properties. The disguise portion has specific wavelength-selective properties that allow it to transmit visible light for display purposes while blocking or disguising upper-bound visible wavelengths that would interfere with near-infrared imaging. This local quality differentiation resolves the contradiction between visibility and imaging quality.
Solution Approach 2:
The disguise portion utilizes wavelength-selective optical properties to differentially transmit or mask different wavelength components of light. By changing the effective 'color' or wavelength composition of transmitted light in different regions, the system achieves both good visible light transmission for display and suppression of interfering wavelengths for imaging.
