Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prolonged exposure to blue light from electronic devices can cause macular degeneration and vision loss, and existing solutions like blue-light blocking glasses require frequent lens replacements and can distort color perception.
Innovation Solution
A yellow backlight system that emits yellow light between 570 nm and 590 nm, using refraction, reflection, or a combination of both, to neutralize and reduce the intensity of blue light emitted by display devices, eliminating the need for glasses and preventing color misjudgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If blue-light blocking glasses are worn to reduce blue light intensity, then the harmful effect on visual cells is reduced, but color perception accuracy deteriorates
Solution Approach 1:
The patent introduces yellow backlight lighting that converts the harmful blue light effect into a beneficial yellow light environment. The yellow light (570-590nm) is positioned adjacent to blue light on the visible spectrum, allowing it to neutralize blue light's harmful effects while maintaining accurate color perception, thus converting a harmful situation into a beneficial one
Solution Approach 2:
The patent changes the spectral parameter of the lighting environment by introducing yellow light with specific wavelength (570-590nm). This parameter change allows the lighting to counteract blue light's harmful effects while preserving color accuracy, avoiding the color distortion caused by blue-light blocking glasses
2Object-affected harmful factors
If blue-light blocking glasses are used to filter blue light, then blue light intensity entering eyes is reduced, but device complexity increases due to lens replacement requirements
Solution Approach 1:
The patent introduces yellow backlight lighting as an intermediary solution between the blue light source and the user's eyes. Instead of modifying the user's glasses, the system adds a yellow light component that neutralizes blue light's harmful effects, eliminating the need for blue-light blocking lenses and their associated maintenance
Solution Approach 2:
The patent replaces the mechanical solution of blue-light blocking glasses (lenses that require cleaning, replacement, and maintenance) with an optical solution of yellow backlight lighting. This substitution eliminates the mechanical complexity of lens maintenance while achieving the same protective effect
3Object-affected harmful factors
If yellow light with wavelength between 570 nm and 590 nm is emitted to neutralize blue light, then blue light intensity is reduced, but energy consumption increases
Solution Approach 1:
The patent applies yellow backlight lighting locally around the display device rather than illuminating the entire environment. By positioning yellow light sources (210, 220) at specific locations (front and back of the display), the system reduces blue light neutralization to only where needed, minimizing unnecessary energy consumption while maintaining effectiveness
Solution Approach 2:
The patent uses partial action by introducing yellow light only in the specific regions where blue light emission occurs (front and back of the display). This partial illumination approach reduces overall energy consumption compared to full-room yellow lighting, while still achieving sufficient blue light neutralization at the critical areas
