Curved Flexible Display Region for Surface Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible displays do not adequately utilize their curvature feature for enhanced image display, limiting the visual experience and functionality of curved substrates in display systems.
Innovation Solution
A display device with a flexible substrate featuring a first display region and a second display region, where the second region is curved and positioned to project images onto a surface, allowing for new visual effects and expanded viewing angles without direct visibility from the perpendicular direction, and incorporating features like lenticular lenses for 3D viewing and touch sensor functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display is curved to utilize its flexibility, then the display can be mounted on curved surfaces and provide new visual effects, but the image in the curved region cannot be directly seen from the perpendicular direction, reducing direct visibility
Solution Approach 1:
The patent transitions the display from a single-plane (2D) configuration to a multi-dimensional (3D) structure by curving the flexible substrate. The display region is bent along a curvature direction, allowing images to be projected onto surfaces in different spatial dimensions. This enables the display to mount on curved surfaces while maintaining image visibility through strategic positioning of the curved display region relative to the viewer's line of sight.
2Adaptability or versatility
If the second display region is positioned where images are not directly visible, then projection onto surfaces becomes possible, but the display complexity increases
Solution Approach 1:
The patent divides the display region into multiple segments: a first display region that displays images directly visible from the perpendicular direction, and a second display region that is curved and positioned to project images onto surfaces. This segmentation allows each region to serve its specific function independently, simplifying the overall system design by clearly defining the roles of different display areas rather than requiring complex control mechanisms for a single unified display.

AI summary
A display device in an embodiment according to the present invention includes a display region arranged above a flexible substrate, the display region including a first display region and a second display region continuing from the first display region, at least the second display region including a curved surface. The second display region is located at a position where an image displayed in the second display region is not seen directly when viewing the first display region from a perpendicular direction with respect to a center part of the first display region.
