Touch-Defined Privacy Display With Local Viewing Angle Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices lack the ability to dynamically adjust privacy regions based on user-defined requirements, as different users need varying privacy settings for different types of content displayed.
Innovation Solution
A display device with a processing unit and a light control unit that allows users to define privacy regions through touch input, controlling the emitting light angle to restrict visibility to a specific area, ensuring privacy by limiting the light emission to a narrow angle range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display uses a fixed privacy region setting, then the anti-peep function is achieved for a specific scenario, but it cannot adapt to different user needs and content types
Solution Approach 1:
The privacy region is transformed from a fixed static setting to a dynamic adjustable region. Users can interact with the display to define different privacy regions based on their needs, and the system can automatically adjust the privacy region based on detected user position and content type. This dynamic adaptation resolves the contradiction by enabling versatility without requiring complex manual configuration for each scenario.
Solution Approach 2:
The system incorporates automatic detection of user position and content type, then autonomously adjusts the privacy region settings without requiring manual user input for each adjustment. The display device serves itself by using sensors and processing units to automatically determine appropriate privacy regions, reducing the operational complexity while maintaining high adaptability.
2Reliability
If the privacy region covers the entire display, then maximum privacy protection is achieved, but the usability and accessibility of the display are reduced
Solution Approach 1:
Instead of applying uniform privacy protection across the entire display, the system identifies and protects only specific local regions where privacy is needed. Users can define privacy regions corresponding to specific content areas, and the system applies privacy controls (such as limiting viewing angles) only to those regions while maintaining normal accessibility to other areas. This localized approach resolves the contradiction by providing targeted privacy protection rather than blanket restrictions.

AI summary
A display device for controlling a privacy region is provided. The display device includes a display unit configured to display images; a touch unit electrically connected to the display unit, wherein the privacy region is determined by the touch unit; and a light control unit electrically connected to the touch unit and configured to control an emitting light angle of the privacy region.
