Curved Display Panels for Seamless Vertical Blind
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vertical blind display devices suffer from diminished display quality due to bezel areas or borders between display panels, which appear as black lines and can cause luminance and color differences between independently controlled panels.
Innovation Solution
The implementation of curved display panels with integrated driver ICs and contact units for image control signal sharing, along with a supporting mechanism that allows panels to rotate and connect seamlessly, eliminating visible bezels and enabling uniform luminance control across panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are arranged to form a large screen, then the display size is increased, but bezel areas appear as black lines diminishing display quality
Solution Approach 1:
The patent applies curvature to the display panels, specifically using flexible OLED technology to create curved display surfaces. This curvature allows panels to be arranged in a circular or arc formation where the edges naturally blend together, eliminating the straight bezel borders that create visible black lines. The curved geometry enables seamless transitions between panels, transforming the harmful straight-edge appearance into an aesthetically pleasing continuous display surface.
2Ease of operation
If display panels are controlled independently, then each panel can be managed separately, but luminance difference and color difference exist between panels diminishing display quality
Solution Approach 1:
The patent merges the control functions by implementing a unified control system that manages all display panels as an integrated unit. The control system includes a controller that generates master control signals and distributes them to multiple display panels, ensuring synchronized operation. This unified approach allows the system to maintain independent panel management capabilities while achieving uniform luminance and color across all panels through centralized coordination and real-time adjustment of control parameters.
3Object-affected harmful factors
If curved display panels are used to eliminate bezels, then display quality is improved, but device complexity increases due to integrated driver ICs and contact units
Solution Approach 1:
The patent implements multi-functionality by designing the bezel area to serve multiple purposes simultaneously. The bezel is not merely a structural border but is integrated with driver ICs for panel control, contact units for signal transmission between panels, and communication circuits for coordinated operation. This universal design allows the same physical structure to perform display control, electrical connection, and data communication functions, reducing the need for separate components and thereby managing complexity through functional integration.
4Manufacturing precision
If multiple display panels are arranged in a fixed configuration, then display consistency is maintained, but portability is reduced due to fixed size and volume
Solution Approach 1:
The patent applies dynamics by making the display panel arrangement adjustable rather than fixed. The support structure incorporates movable and rotatable components that allow panels to be repositioned, reconfigured, or collapsed. This dynamic design enables the display system to maintain consistent visual output when assembled while reducing to a compact form for portability. The rotatable support structure specifically allows panels to rotate into different positions, enabling both expanded display configuration and compact storage position.

AI summary
A blind display device includes a plurality of curved display panels, a support, and a plurality of rotators. Each of the curved display panels includes a curved display area between a flat display area and a bezel area. The support guides movement of the curved display panels. The rotators couple corresponding ones of the curved display panels to the support and rotate corresponding ones of the curved display panels.
