Foldable Display Privacy Shielding via Translucent Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible display devices, such as foldable smartphones, face the issue of increased information leakage when transitioning from a closed to an open state, as larger screens reveal sensitive information to third parties, potentially exposing personal or secret data.
Innovation Solution
An information processing device with a processor-controlled display mechanism that overlays a translucent shielding image on the primary display when transitioning from a folded to an unfolded state, reducing visibility and mitigating information leakage by setting conditions based on location, time, app type, and communication type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display mechanism is unfolded to display information on a large screen, then the display area is increased, but the risk of information leakage to third parties is increased
Solution Approach 1:
The system detects the unfolded state in advance and proactively displays a shielding image before the user can be harmed by information leakage. This preliminary action prevents the harmful effect from occurring in the first place, rather than reacting after the damage is done.
Solution Approach 2:
A translucent shielding image is introduced as an intermediary element between the displayed information and potential third-party observers. This mediator reduces the visibility of sensitive information while still allowing the user to see and interact with the content on the unfolded screen.
2Object-affected harmful factors
If a translucent shielding image is displayed to reduce information leakage, then the visibility of sensitive information is lowered, but the user's ability to see and operate the screen is reduced
Solution Approach 1:
The shielding image's transparency parameter is carefully adjusted to achieve the optimal balance. By changing the transparency parameter, the system reduces information leakage risk while maintaining sufficient visibility for the user to see and operate the screen effectively.
Solution Approach 2:
The shielding effect is applied selectively rather than uniformly across the entire screen. The translucent shielding image allows different regions to have different levels of transparency, maintaining ease of operation for interactive elements while protecting sensitive information areas.
3Area of stationary object
If the display mechanism transitions from closed to open state, then the screen size increases, but the sudden display of large images increases peeping risk
Solution Approach 1:
The system detects the transition to unfolded state in advance and immediately displays the shielding image before the full-screen content becomes visible to third parties. This preliminary protective action prevents peeping risk during the critical transition moment.
Solution Approach 2:
The shielding image is displayed in advance as a countermeasure against the potential harm of peeping. This preliminary anti-action neutralizes the increased peeping risk that would otherwise result from the sudden expansion to a large unfolded screen.

AI summary
An information processing device includes an openable display mechanism that displays a first screen in a first display region in a closed state and displays a second screen in a second display region having a larger area than the first display region in an open state, and a processor configured to execute a display process of lowering a visibility of the second screen when the display mechanism in the closed state changes to the open state.
