Wallpaper Display System with Projected Content Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content display systems using projectors lack the ability to create background display content that maintains correlation with projected content, apply three-dimensional effects, and easily interchange display content items on wallpaper backgrounds.
Innovation Solution
A content display system and method that involves creating first and second display content layers, storing them, and projecting the second content onto the first to maintain visual relationship, applying three-dimensional effects by combining image layers, and allowing for easy interchange of content items using a creation processing unit, storage unit, and display processing unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple image content items are combined and projected, then visual richness is improved, but system complexity increases
Solution Approach 1:
The system segments display content into multiple independent image layers (first image layer, second image layer, third image layer) that can be selectively combined. Each layer represents a distinct content item that can be independently controlled, stored, and projected, allowing visual richness without overwhelming system complexity through modular design.
Solution Approach 2:
The system dynamically selects and combines different image layers based on control signals. The display processing unit can interchange which image layers are projected at different times, enabling flexible composition of multiple content items. This dynamic control allows the system to present rich visual content while maintaining manageable complexity through programmable selection rather than permanent fixed combinations.
2Productivity
If image content items are interchanged at regular time intervals, then display dynamics are improved, but control complexity increases
Solution Approach 1:
The system implements periodic interchange of image content items at predetermined time intervals. The display processing unit automatically cycles through different combinations of image layers based on timing signals, providing dynamic display changes without requiring complex real-time control decisions. This periodic operation simplifies the control logic while maintaining display vitality.
Solution Approach 2:
Multiple image layers are pre-prepared and stored in advance in the storage unit before projection. The creation processing unit generates these image layers beforehand, and the display processing unit simply retrieves and projects them according to the predetermined schedule. This preliminary preparation reduces runtime control complexity while enabling dynamic display interchange.
3Stability of the object's composition
If background image and projected image are integrated, then visual unity is improved, but edge visibility becomes problematic
Solution Approach 1:
The system applies different processing to different regions of the display. The first image layer serves as a background with specific visual characteristics, while the second and third image layers are projected in specific regions with controlled transparency. This local differentiation allows the background and projected content to integrate visually while maintaining distinguishable boundaries where needed.
Solution Approach 2:
The system utilizes transparency and color properties of image layers to achieve integration. By controlling the transparency of the first image layer and the color characteristics of projected layers, the system creates visual unity between background and foreground content. The edge visibility issue is addressed through careful control of layer transparency and color matching rather than sharp boundaries.

AI summary
Wallpaper serving as a screen and display content such as an image to be projected onto the wallpaper are created while maintaining their correlation. The created display content is projected on the wallpaper. The content display system creates a background image, which is a first image serving as a screen, and a second image for a predetermined area on the first image while maintaining their visual relationship, and forms a composite image of the second image on the first image by projecting the second image from a projector onto the predetermined area of the first image.
