Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital signage systems are limited to two-dimensional information display, reducing their applicability and immersion level, and lack the ability to actively respond to events such as movement of display devices.
Innovation Solution
A digital signage system comprising multiple display devices with a server that includes a communication unit, sensor unit, and controller to control the display devices based on movement data, applying techniques like light shielding, split-depth effects, and luminance control to create stereoscopic content and enhance immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display devices are arranged horizontally to increase display area, then the available area is increased, but the information presentation remains limited to two-dimensional and immersion level is reduced
Solution Approach 1:
The patent applies dimensionality change by transitioning from traditional horizontal 2D arrangement to a vertical stacked configuration with transparent displays. Multiple display devices are arranged in the depth dimension (z-axis) rather than only in the horizontal plane, enabling 3D stereoscopic content presentation while maximizing the use of limited spatial area. This resolves the contradiction by adding a new dimension for information presentation.
Solution Approach 2:
The patent implements nesting by placing display devices within each other's spatial footprint through transparent display technology. The first, second, and third display devices are stacked vertically with each device positioned in front of the previous one, creating a nested configuration where multiple displays occupy the same horizontal space but differ in depth positioning, thereby increasing display area without expanding horizontal footprint.
2Device complexity
If display devices are arranged in a fixed configuration, then the system structure is simple, but the system cannot actively respond to events such as movement of display devices
Solution Approach 1:
The patent applies dynamics by introducing movement detection capability through sensors that monitor the positions and movements of display devices. The system transitions from a static fixed configuration to a dynamic system that can detect and respond to changes in device positioning, enabling active response to events while maintaining relatively simple system structure through sensor-based monitoring.
Solution Approach 2:
The patent implements feedback by using sensors to detect the positions and movements of display devices and feeding this information back to the control system. This feedback mechanism enables the system to actively respond to events such as device movement by adjusting content presentation accordingly, while keeping the overall system structure relatively simple through sensor-based monitoring and automatic adjustment.
3Device complexity
If all display devices display the same content simultaneously, then the system control is simple, but the immersion level and stereoscopic effect are reduced
Solution Approach 1:
The patent applies local quality by assigning different content or different perspectives of the same content to different display devices based on their positional characteristics. Each display device presents content tailored to its specific location in the stacked configuration, with the first, second, and third devices displaying different layers or perspectives of 3D content, thereby enhancing stereoscopic effects while maintaining manageable system control through position-based content differentiation.

AI summary
A digital signage system and a data processing method in the same are disclosed. The digital signage system comprises a plurality of display devices displaying a signage content; and a server including a communication unit for transmitting signage content data to each display device, a sensor unit for sensing movement of the plurality of display devices, and a controller for controlling the display devices of which display areas are overlapped, differently from each other on the basis of the sensed movement data of the display devices, if display areas of at least two of the plurality of display devices are overlapped with each other at a predetermined threshold value or more.
