Bezel-less Flexible Display with Rounded Flat Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have a bezel area that limits their application and aesthetics, as they cannot fully utilize the screen real estate due to the presence of a non-display border.
Innovation Solution
A bezel-less display device design featuring a flexible display panel with a flat display area and flexible display areas extending from it, where the flat display area has a rounded vertex, and the flexible display areas are bent to form angles greater than 90 degrees and less than 150 degrees with the flat display area, allowing the device to be bent and eliminating the bezel when viewed from the front.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a conventional display device with a bezel area is used, then the display device provides structural support and protection, but the bezel area limits screen real estate and reduces aesthetic appeal
Solution Approach 1:
The patent extracts and removes the traditional bezel structure from the display device. The flexible display panel is configured to extend beyond the front area boundaries, eliminating the need for a separate bezel area. This extraction principle directly increases screen real estate by removing the non-display border that traditionally framed the display.
Solution Approach 2:
The patent transitions from a two-dimensional flat display with borders to a three-dimensional flexible display that wraps around the edges of the device. By bending the flexible display panel along curved surfaces and extending it to the side areas, the display utilizes the third dimension (depth/curvature) to eliminate the bezel while maintaining structural integrity.
2Area of stationary object
If the flexible display panel is extended to side areas and bent, then the bezel is eliminated and screen real estate is maximized, but the structural protection and stability may be compromised
Solution Approach 1:
The patent employs dynamic structural elements including bent portions and curved surfaces that allow the flexible display panel to adapt to different structural configurations. The display panel can be bent along curved surfaces and extended to side areas while maintaining flexibility and structural integrity, enabling the display to achieve both extended area and structural stability.
Solution Approach 2:
The patent utilizes composite material structures where the flexible display panel is integrated with support frameworks and curved surfaces. This composite approach combines the flexibility of the display material with the structural strength of supporting elements, allowing the display to extend to side areas while maintaining reliability and protection.
3Shape
If the flexible display panel is bent to form angles greater than 90 degrees and less than 150 degrees, then the bezel-less appearance is achieved, but the manufacturing precision and alignment difficulty increase
Solution Approach 1:
The patent divides the flexible display panel into distinct functional regions: a front area for primary display, side areas for extended display, and bent portions connecting them. This segmentation allows each region to be manufactured and aligned independently with specific angle requirements (greater than 90 degrees and less than 150 degrees), simplifying the overall manufacturing process while achieving the bezel-less configuration.

AI summary
A display device may include a window panel including a front area and side areas extended from the front area and a flexible display panel disposed under the window panel, the flexible display panel including a flat display area corresponding to the front area and flexible display areas extended from the flat display area. At least one vertex of the flat display area is rounded.
