Dual-Projector Display Device for Non-Inverted Dual-Side Image Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies fail to effectively facilitate collaboration and communication between individuals by not allowing simultaneous, non-inverted image projection on both sides of a screen, and lack adaptive image display modes based on viewer presence and interest levels.
Innovation Solution
A display device with dual projectors and a controller that switches between projecting non-inverted images on both sides of a double-sided screen, using sensors to detect viewer presence and adjust image display states based on interest levels, allowing for adaptive and interactive communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single projector is used to project images, then device complexity is reduced, but the ability to display non-inverted images simultaneously on both sides of the screen is lost
Solution Approach 1:
The system divides the projection function into two separate projectors: a first projector for projecting images to the first surface and a second projector for projecting images to the second surface. This segmentation allows each projector to independently control image display on its designated surface, enabling simultaneous non-inverted image display on both sides without requiring a single complex projector to handle both surfaces.
2Adaptability or versatility
If images are projected on both surfaces of the screen, then adaptability for different viewing positions is improved, but device complexity increases due to requiring multiple projectors
Solution Approach 1:
The controller serves multiple functions by managing both the first and second projectors, controlling image projection to both surfaces, detecting viewer presence on either side of the screen, and switching between different projection modes. This multi-functionality allows the system to provide adaptability for different viewing positions while avoiding the need for separate control systems for each projector.
3Ease of operation
If the controller switches between first and second projectors, then seamless image transition is achieved, but switching control complexity increases
Solution Approach 1:
The system uses sensors to detect the presence of viewers on either side of the screen and provides feedback to the controller. Based on this feedback, the controller automatically switches between the first and second projectors to ensure that images are always displayed on the appropriate surface for the current viewer position. This feedback mechanism simplifies the switching control logic by making it responsive to actual usage conditions rather than requiring complex predetermined switching sequences.

AI summary
A display device includes a screen, first and second projectors, and a controller. The screen has first and second surfaces. The first projector projects a first horizontally non-inverted image as viewed from the first surface. The second projector projects a second horizontally non-inverted image as viewed from the second surface. The controller controls switching of an operation between the first and second projectors and also performs control so that the first horizontally non-inverted image projected on the first surface will be projected on the second surface and so that the second horizontally non-inverted image projected on the second surface will be projected on the first surface.
