Privacy Display Driver IC for Smartphone Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of smartphones face the risk of exposing personal information in public places due to the lack of effective privacy protection for displayed content, limiting their ability to view sensitive information outside of private settings.
Innovation Solution
An electronic device with a display, processor, and display driver IC that generates and applies a privacy effect to specific portions of images, allowing only the user in front of the device to view personal information while obscuring it from others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If personal information is displayed on the smartphone screen in public places, then the user can access and view the information, but the information becomes exposed to others and privacy is compromised
Solution Approach 1:
The patent applies different display qualities to different regions of the screen. The central region (where the user's face is positioned) displays clear, high-quality personal information, while the peripheral regions display blurred or obscured content. This spatial differentiation of display quality enables the user to view sensitive information clearly while preventing others from seeing it, thus resolving the contradiction between accessibility and privacy protection.
2Measurement precision
If the smartphone display shows content clearly to the user, then the user can read personal information easily, but others can also see the content and privacy is compromised
Solution Approach 1:
The display system dynamically adjusts the quality of content rendering based on the spatial position of the viewer. When the user's face is detected in the central region, that area receives high-clarity rendering suitable for reading personal information. Meanwhile, peripheral regions are rendered with reduced clarity or obscured content, ensuring that only the authorized user can view the information clearly while others see only blurred content.
3Object-affected harmful factors
If a privacy filter is applied to the entire display, then privacy is protected, but the user cannot clearly view the personal information
Solution Approach 1:
Rather than applying a uniform privacy filter across the entire display, the system selectively applies privacy protection only to specific regions. The central region corresponding to the user's face position maintains full clarity for reading personal information, while peripheral regions receive the privacy filter effect. This localized application of privacy protection resolves the contradiction by ensuring both readability for the user and privacy protection from others.
4Ease of operation
If the display shows all content uniformly, then the device is simple to operate, but privacy protection is not achieved in public places
Solution Approach 1:
The display system automatically detects the user's face position and dynamically adjusts the privacy protection regions without requiring manual configuration. The system self-adapts to different usage scenarios, automatically determining which areas of the screen should be protected based on the detected face position. This automated approach maintains ease of operation while effectively addressing privacy risks in public places.
