Transparent Screen Tinting for Glare Relief Without View Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light management systems that adjust transparency to mitigate bright light sources often obstruct the view and are intrusive, failing to provide effective relief from blinding light while maintaining optimal visibility.
Innovation Solution
A light management system with a sensor unit and control unit that dynamically tints specific portions of a transparent screen based on light intensity and position relative to the user's eyes, using cameras and light sensors to determine and predict viewing directions and light source positions, allowing for adjustable transparency levels and personalized adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional systems adjust transparency of windows to mitigate bright light sources, then relief from blinding light is provided, but the view of the surrounding environment is greatly limited
Solution Approach 1:
The patent divides the transparent screen into multiple independently controllable zones or pixels. Each segment can be individually tinted based on the position and intensity of light sources relative to the user's eye, allowing only the necessary portions to be darkened while keeping other areas transparent. This segmentation enables selective light blocking without globally obscuring the view.
Solution Approach 2:
The system applies different transparency properties to different regions of the transparent screen based on local lighting conditions and user gaze direction. Areas where light sources intersect with the user's line of sight are tinted, while other regions maintain full transparency. This local quality approach ensures that transparency is optimized for each specific region rather than applying a uniform setting across the entire screen.
2Object-affected harmful factors
If the transparent screen is tinted to prevent blinding, then protection from light sources is achieved, but the system becomes intrusive and disturbs the user
Solution Approach 1:
The system automatically detects light sources, determines the user's gaze direction using eye tracking sensors, and dynamically adjusts transparency without requiring manual user input. The transparent screen serves itself by responding autonomously to environmental conditions and user behavior, eliminating the intrusiveness of manual operation while providing timely protection from blinding light.
Solution Approach 2:
The transparency of the screen is dynamically adjusted in real-time based on changing light conditions and user gaze direction. Rather than being static or requiring manual activation, the system continuously adapts its transparency level to match current conditions, providing seamless and natural protection that enhances user comfort rather than disturbing it.
3Object-affected harmful factors
If the entire transparent screen is tinted to block light, then complete protection is provided, but visibility of the environment is obstructed
Solution Approach 1:
The transparent screen is divided into multiple independently controllable segments or pixels that can be selectively tinted. Only the specific segments where light sources intersect with the user's line of sight are darkened, while all other segments remain transparent. This segmentation allows the system to provide targeted light protection without globally reducing visibility of the surrounding environment.
Solution Approach 2:
Different transparency properties are applied to different regions of the screen based on local lighting conditions and gaze direction. Regions requiring light blocking have reduced transparency, while other regions maintain full transparency to preserve environmental visibility. This local quality approach optimizes the balance between protection and visibility for each specific area of the screen.

Data Source
AI summary
A light management system comprises a sensor unit and a control unit, wherein the sensor unit is configured to determine an intensity of a light source on a first side of a transparent screen, the sensor unit is further configured to, if the intensity of the light source is greater than a defined threshold, determine a position of the light source with respect to the eyes of a person located on a second side of the transparent screen, if, based on the position of the light source with respect to the eyes of the person, it is determined by the control unit that the light source may be blinding the person, the control unit is configured to tint at least a portion of the transparent screen to prevent the person from being blinded by the light source.
