Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic displays struggle with visibility issues due to ambient lighting conditions, requiring manual adjustment or relocation by users, which is inconvenient, especially in vehicles where important information is difficult to view.
Innovation Solution
A dynamically adjustable display system using a flexible cold-bent glass substrate that can bend reversibly in response to ambient lighting conditions, controlled by a control unit and adjustable support mechanism to optimize visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a fixed rigid display is used, then manufacturing is simple and structure is stable, but visibility is poor under bright ambient light conditions
Solution Approach 1:
The display transitions from a fixed rigid structure to a dynamically adjustable structure that can change its orientation angle in response to ambient lighting conditions. The flexible substrate and support mechanism enable the display to dynamically adapt its position to optimize visibility under varying light conditions.
Solution Approach 2:
The display system changes the orientation angle parameter of the display panel in response to ambient lighting conditions. By adjusting this geometric parameter, the system optimizes the display's visibility and reduces glare from direct or reflected light sources.
2Ease of operation
If manual adjustment of display position is required, then device structure is simple, but ease of operation deteriorates due to user intervention needed
Solution Approach 1:
The display system performs self-adjustment by automatically detecting ambient lighting conditions and changing its orientation angle without user intervention. The photodetector, control unit, and support mechanism work together to enable the display to serve itself in optimizing visibility.
Solution Approach 2:
The system incorporates a feedback loop where photodetectors continuously monitor ambient lighting conditions, the control unit processes this information, and the support mechanism adjusts the display angle accordingly. This closed-loop feedback system enables automatic adaptation to changing light conditions.
3Adaptability or versatility
If display is fixed in vehicle, then installation is simple, but adaptability to different lighting conditions during driving is poor
Solution Approach 1:
The display system serves multiple functions: it displays information, automatically adjusts its orientation angle, and adapts to various ambient lighting conditions encountered during driving. This multi-functionality makes the display universally applicable to different driving scenarios without requiring separate adjustment mechanisms for each condition.

AI summary
Dynamically adjustable display systems for adjusting the position of a flexible display in response to ambient light. The display system includes a flexible display that is capable of reversibly bending along one or more bending axes. The display system further includes an adjustable support on which the flexible display is mounted, the adjustable support being able to selectively bend the flexible display. The display system includes photodetectors for detecting ambient light. The photodetectors may be positioned about a perimeter of the flexible display. A control unit in communication with the adjustable support and the plurality of photodetectors may cause the adjustable support to bend the flexible display in response to ambient light detected at the plurality of photodetectors.
