Bent Pad Area Reducing Bezel Width in Flexible Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices have a significant bezel area that limits the size of the display area and restricts design flexibility, particularly in electronic devices like mobile devices, where the bezel area width is not minimized effectively, affecting both the ergonomic grip and aesthetic design.
Innovation Solution
A flexible display panel with a cover window design where the pad area is bent under the display area, reducing the width of the bezel areas, especially the left and right bezel areas, and allowing for a more compact design by eliminating the need for the pad area to be covered by the lower bezel, thus enabling a wider display area and improved aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pad area is disposed at the bottom bezel area to cover mounting components, then the components can be securely mounted, but the width of the bottom bezel area increases
Solution Approach 1:
The pad area is bent from a planar configuration into a three-dimensional structure that extends downward beneath the display area. This dimensional change allows the pad area to cover mounting components at the bottom bezel without increasing the visible bezel width, as the pad area wraps around to the rear side of the display device.
Solution Approach 2:
The bent pad area is positioned within the space created by the display area extending over the bottom bezel area. The display area effectively nests over the bent pad area, allowing the pad area to cover mounting components while remaining concealed within the overall device structure.
2Area of stationary object
If the bezel area width is reduced to increase display area, then the display area size increases, but the components may interfere with the bent pad area
Solution Approach 1:
Mounting components are extracted from the display area region and repositioned to the bottom bezel area. This separation allows the display area to extend to the edges without interference, while the bent pad area provides a dedicated mounting zone at the bottom bezel where components can be securely installed.
Solution Approach 2:
The bent pad area serves as an intermediary structure between the display area and the mounting components. It provides a transition zone that allows components to be mounted at the bottom bezel while preventing direct interference with the display area, as the bent pad area absorbs the spatial conflict.
3Length of stationary object
If the pad area is bent under the display area, then the left and right bezel widths are reduced, but the pad area structure becomes more complex
Solution Approach 1:
The pad area is constructed as a flexible structure that can be bent into the required three-dimensional configuration. This flexibility allows the pad area to wrap around from the bottom edge of the display area and extend beneath it, creating the necessary structure to cover mounting components while maintaining a compact overall form.
