Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable display devices lack the ability to effectively display stereoscopic images and enhance three-dimensional effects, while also improving visibility and luminance in transparent display panels.
Innovation Solution
A foldable display device incorporating a transparent display panel and a floating screen connected to a non-transparent display panel, utilizing a gap maintaining unit and a floating screen with asymmetric concave portions to increase mounting angle and enhance three-dimensional effects, along with a slidable back plate to minimize luminance differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a floating screen is added to enhance three-dimensional effect, then the three-dimensional effect is improved, but the device complexity increases
Solution Approach 1:
The floating screen is integrated within the display panel structure, nesting the additional three-dimensional component inside the existing device framework rather than adding it as an external attachment, thus enhancing 3D effect while minimizing complexity increase
Solution Approach 2:
The floating screen function is merged with the display panel assembly, combining multiple functions (display and 3D effect generation) into a single integrated structure, reducing the number of separate components and simplifying the overall device
2Shape
If the mounting angle of floating screen is increased to enhance three-dimensional effect, then the three-dimensional effect is improved, but the available area of display panel is reduced
Solution Approach 1:
The floating screen is positioned at an optimized angle that utilizes the third dimension (depth) rather than merely occupying horizontal display area, allowing three-dimensional effect enhancement without proportionally reducing the two-dimensional display area
Solution Approach 2:
The mounting angle of the floating screen is designed to be adjustable or optimized based on viewing conditions, allowing the system to dynamically balance between three-dimensional effect and available display area rather than being fixed at a suboptimal angle
3Area of stationary object
If a transparent display panel is used to increase available area, then the available area is improved, but the visibility and luminance are reduced
Solution Approach 1:
The display panel employs different transparency characteristics in different regions or layers, with the transparent portion allowing light transmission for increased area while incorporating optical enhancement features in specific zones to maintain visibility and luminance where needed
Solution Approach 2:
The transparent display panel utilizes composite material structures combining transparent substrates with optical enhancement layers or coatings that improve luminance and visibility while preserving the transparency-induced area benefits

AI summary
A foldable display device includes a display panel in which at least a partial area includes a transparent display panel; and a floating screen connected to the display panel and reflecting an image displayed on the display panel. Therefore, a foldable display device which uses a floating screen and a display panel to display an image has more three-dimensional effect.
