Transparent Display Glare Shielding via Eye and Light Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems and external monitoring systems are affected by strong light sources, leading to glare that compromises driver safety and comfort, as well as image quality in outdoor settings.
Innovation Solution
A transparent display system that includes a transparent display unit positioned between image acquiring units and external light sources, with position determination units for both, a projective coordinate calculation unit to identify areas needing adjustment, and a control unit to generate display control signals for shielding or adjusting the display state of these areas to mitigate glare.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transparent display unit is used to display information, then visibility and transparency are improved, but glare from external light sources affects driver safety and comfort
Solution Approach 1:
The display area of the transparent display unit is segmented into multiple independent pixel regions, allowing selective control of each pixel's transparency and brightness. This enables the system to block glare in specific areas while maintaining visibility in other areas, resolving the contradiction between display visibility and glare prevention.
Solution Approach 2:
The transparent display unit dynamically adjusts the transparency and brightness of each pixel in real-time based on the position of external light sources and the driver's line of sight. This dynamic adaptation allows the display to maintain visibility while actively preventing glare from affecting driver safety and comfort.
2Object-affected harmful factors
If the transparent display unit blocks external light sources, then glare is reduced, but the transparency and view through the display are compromised
Solution Approach 1:
Different regions of the transparent display unit have different transparency properties. Pixels that would cause glare are made opaque or less transparent, while other pixels maintain full transparency. This local differentiation allows glare reduction in specific areas without compromising overall transparency and view quality.
3Ease of operation
If the display adjusts to block light in certain areas, then driver comfort is improved, but the display complexity and control requirements increase
Solution Approach 1:
The system uses position determination units to detect the location of external light sources and the driver's eyes, then feeds this information back to the control unit. The control unit processes this feedback and adjusts each pixel's transparency accordingly, creating a closed-loop system that automatically maintains driver comfort without requiring manual intervention.
Solution Approach 2:
The transparent display unit autonomously adjusts its transparency and brightness characteristics based on real-time detection of light source positions and driver eye position. The system serves itself by automatically adapting to changing conditions without requiring external control, thereby improving driver comfort while managing complexity through automation.

AI summary
The embodiment of the present disclosure provides transparent display system and vehicle equipment provided with the same. The transparent display system may comprise: a transparent display unit positioned between user's eyes and an external light source; a position determination unit for the user's eyes configured to determine a position of user's eyes; a position determination unit for the light source configured to determine a position of the external light source; a projective coordinate calculation unit configured to calculate coordinate distribution of a projective area based on the position of the user's eyes and the position of the external light source, the projective area being a region through which the user watches and suffers from blaring so as to be shielded; and a control unit configured to generate a display control signal based on the coordinate distribution information of the projective area; the shielding is along the viewing direction of the user so as to display based on the display control signal to implement appropriate shielding in the projective area.
