Transparent Display Color Matching for Rear-Surface Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with transparent displays unintentionally expose sensitive information on their rear surfaces due to similar color and brightness, compromising the visibility of information on the front surface.
Innovation Solution
The device identifies the position and size of content requiring security on the front surface, adjusts the color and brightness of an object on the rear surface to match, thereby reducing visibility on the rear while maintaining visibility on the front.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rear surface is overlaid with the same color and brightness as the information to protect security, then the visibility of information requiring security is improved, but the visibility of the information on the front surface is decreased
Solution Approach 1:
The patent applies different color and brightness characteristics to different regions of the display. The rear surface overlay is applied only to specific regions corresponding to sensitive information, while other regions maintain their original appearance. This localized approach allows security protection where needed without compromising overall visibility.
Solution Approach 2:
The patent dynamically changes the color and brightness properties of the rear surface overlay based on the content being displayed. By adjusting these optical properties in response to detected content characteristics, the system can protect sensitive information while maintaining visibility of important information on the front surface.
2Reliability
If the rear surface is overlaid with the same color and brightness as the information to protect security, then the visibility on the rear surface is decreased, but the resource consumption for brightness adjustment increases
Solution Approach 1:
Instead of applying full brightness adjustment across the entire display, the patent applies brightness changes only to the specific regions where sensitive information is detected. This partial action approach reduces the overall resource consumption while still providing effective protection where needed.
Solution Approach 2:
The patent optimizes brightness adjustment by detecting content characteristics and applying appropriate brightness levels selectively. By changing parameters based on content analysis rather than applying uniform adjustments, the system achieves effective information protection with reduced computational and energy resources.

AI summary
An electronic device is provided. The electronic device includes a transparent display capable of displaying content on a front surface part and a rear surface part, and at least one processor operatively connected to the transparent display, wherein the at least one processor can be configured to identify the position and size of content, for which security is required, in a screen image displayed on the front surface part, identify the color and/or the brightness of an object corresponding to the content, and display the object having the identified color and brightness on a region of the rear surface part determined based on the position and the size of the content.
