Light Array Switching for Secret Digital Signage Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for digital signage struggle to attract attention from a general audience without specialized instruments, as they require synchronization with the display environment and may not effectively engage uninterested viewers.
Innovation Solution
A method using a light array that switches between information and concealment arrays at high speed, creating a cycle where the information array is invisible to casual viewers, and can be revealed by intermittent blocking of the visual field, allowing concealed information to be accessed without special instruments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If special information is displayed on digital signage using conventional methods, then specific people can receive targeted information, but the general public cannot access the information without specialized instruments
Solution Approach 1:
The patent uses color changes and luminance modulation to encode information. By alternating between information display and concealment display at high speed, the system enables information to be perceived through color or brightness changes without requiring specialized optical instruments, thus making the information accessible to the general public while maintaining security
Solution Approach 2:
The system employs periodic switching between information array and concealment array at high frequency. This periodic action allows the information to be temporarily visible and then concealed, creating a temporal coding mechanism that can be decoded by simple visual attention control without specialized equipment
2Loss of information
If information is displayed on digital signage to attract attention, then viewers can access information, but the information may be easily perceived by unintended viewers
Solution Approach 1:
The system switches between information array and concealment array at high frequency, creating a temporal pattern that allows intended viewers to access information through synchronized visual attention while preventing unintended viewers from perceving the information securely
Solution Approach 2:
The display dynamically transitions between information display and concealment states. This dynamic behavior allows the system to adapt to different viewing conditions and control information accessibility in real-time without requiring complex user interactions
3Productivity
If display contents are changed frequently to attract attention, then viewer engagement increases, but the information cannot be read properly
Solution Approach 1:
The system uses high-speed periodic switching between information array and concealment array, creating a temporal coding effect. This allows the display to change contents frequently for engagement while maintaining information integrity through synchronized viewing, resolving the contradiction between engagement and readability

AI summary
The present invention provides a method for providing information and an apparatus for providing information with which information can be secretly displayed, and further, a display technique with a lot of sense of fun can attract keen interest from people around a display such as digital signage.A method for providing information using an apparatus for providing information that displays information using a light array includes: switching and displaying an information array and a concealment array in a display cycle in which a person cannot sense an information display array of the information array using the apparatus for providing information. The information array includes the information display array concerning information to be provided, and the concealment array is generated so that the information display array becomes invisible when the concealment array overlaps with the information array. The information to be transmitted can be secretly included in a normally displayed array (such as an image or a panel) for display. Since appropriately and intermittently blocking light entering a person's eye is only required, the person can acquire the information to be transmitted without a special instrument.
