Adjustable Micro-Louvers for Selective Screen Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen privacy solutions, such as films, are not adjustable and dim the display, as they do not allow for selective control of viewing angles or direction, and are not transparent enough, limiting user flexibility in public settings.
Innovation Solution
A system with adjustable micro-louvers adjacent to pixels that can extend, retract, or telescope to dynamically control viewing angles in various directions, allowing users to manually or automatically adjust privacy settings based on content or detected viewers, without dimming the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a fixed viewing angle film is placed over the screen, then viewing angle privacy is improved, but display brightness is reduced due to light absorption
Solution Approach 1:
The patent replaces fixed viewing angle films with dynamic micro-louvers that can adjust their orientation and position in real-time. Each micro-louver is independently controllable to block light from specific angles while allowing light from other angles to pass through, providing adaptive privacy control without permanently dimming the display.
Solution Approach 2:
The patent changes the physical state and orientation parameters of the micro-louvers to control viewing angles dynamically. By adjusting the tilt angle and position of each micro-louver, the system can selectively block or allow light transmission in different directions, replacing the static parameter of traditional films with dynamic adjustable parameters.
2Object-affected harmful factors
If a fixed viewing angle film is used, then privacy control in one direction is improved, but flexibility to adjust viewing angles in multiple directions is lost
Solution Approach 1:
The patent divides the screen into multiple zones with independent micro-louvers for each direction (up, down, left, right). Each segment can be controlled independently to provide different viewing angle restrictions in different directions, allowing flexible privacy control tailored to specific viewing scenarios.
Solution Approach 2:
The system transitions from static fixed-angle films to dynamic adjustable micro-louvers that can change their orientation in real-time. This allows the viewing angle control to adapt to different user positions and privacy requirements in multiple directions simultaneously.
3Object-affected harmful factors
If traditional privacy films are used, then viewing angle limitation is improved, but user control over selective privacy settings is lost
Solution Approach 1:
The system incorporates automatic detection of viewer positions and content type to autonomously adjust micro-louver configurations. The system can self-regulate privacy settings based on detected conditions, reducing the need for manual user intervention while maintaining flexibility when users do provide input.
Solution Approach 2:
The patent implements dynamic control mechanisms that allow real-time adjustment of viewing angles based on user input, detected viewer positions, or content characteristics. This replaces the static, non-adjustable nature of traditional films with an interactive, adaptable system that responds to changing conditions.

AI summary
A system and method adjusts the viewing angle of a display based on user input and/or automatically based on content and/or detected viewers. The viewing angle changes may be limited to certain portions of the display or the whole display. The system and method may change viewing angles in different direction separately and independently.
