Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-peeping technologies, such as light control films, have fixed anti-peeping angles and cannot be adjusted or switched in real time to meet different display needs.
Innovation Solution
An electronic device with a light-adjustable control panel that includes a plurality of light control units, allowing it to switch between different displaying modes by altering the transparent and non-transparent states of these units, thereby adjusting the anti-peeping angle or switching the displaying mode in real time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a light control film is attached to the display for anti-peeping, then the anti-peeping effect is improved, but the anti-peeping angle becomes fixed and cannot be adjusted in real time
Solution Approach 1:
The patent applies the dynamics principle by replacing the static light control film with a dynamic light control panel comprising multiple independently controllable light control units. These units can dynamically adjust their transparent and non-transparent states in real-time, enabling the anti-peeping angle to be adjusted according to different viewing requirements while maintaining the anti-peeping effect.
Solution Approach 2:
The patent implements parameter changes by controlling the optical parameters (transparent/non-transparent state) of each light control unit individually. By changing the optical parameters of different light control units, the system can adjust the anti-peeping angle and switching between display modes (transparent mode, anti-peeping mode, reflective mode) in real-time to meet varying display needs.
2Object-affected harmful factors
If a light control film is used for anti-peeping, then light with large emitting angle is filtered, but the displaying mode cannot be switched for different needs in real time
Solution Approach 1:
The patent applies segmentation by dividing the light control panel into multiple independent light control units, each capable of being controlled independently. This segmentation enables different regions of the display to be configured in different modes (transparent, anti-peeping, reflective) simultaneously or sequentially, providing flexible mode switching capability while maintaining effective light filtering for anti-peeping.
Solution Approach 2:
The patent implements dynamics by enabling real-time switching between different displaying modes through dynamic control of the light control units' states. The system can switch between transparent mode (all units transparent), anti-peeping mode (alternating transparent and non-transparent units), and reflective mode (all units non-transparent), adapting to different display needs in real-time.
3Ease of manufacture
If the anti-peeping angle is fixed after manufacture, then the manufacturing process is simple, but the application scope is restrained
Solution Approach 1:
The patent implements universality by designing a light control panel that can perform multiple functions: transparent display mode, anti-peeping mode with adjustable angles, and reflective mode. This multi-functional design expands the application scope to cover various scenarios (privacy protection, public display, energy saving) while maintaining a relatively simple manufacturing process based on existing light control unit technologies.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The electronic device achieves an anti-peeping effect by directing the image display in a specific direction, making it difficult for unauthorized individuals to view, while also allowing for real-time adjustments to meet varying display requirements.

AI summary
The present disclosure provides an electronic device including a display and a light-adjustable control panel including a plurality of light control units. The light-adjustable control panel includes a first substrate, a second substrate, and a display medium sandwiched between the first substrate and the second substrate. In a first displaying mode, the light control units form a plurality of first transparent regions and a plurality of non-transparent regions alternately arranged, and in a second displaying mode, the control units form a second transparent region. A ratio of a total area of the first transparent regions to a total area of the light control units is different from a ratio of an area of the second transparent region to the total area of the light control units.
