Curved Display Panel Assembly for Higher Screen-to-Body Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to achieve a high screen-to-body ratio, particularly in bezel-less designs, limiting their aesthetic appeal and functional efficiency.
Innovation Solution
A display device with a curved display area and a fixing member that includes a flat and curved portion, attached to a connection region between a display panel and a window, enhancing the screen-to-body ratio by optimizing the utilization of internal space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a flat screen design is used, then the manufacturing process is simple, but the screen-to-body ratio is low
Solution Approach 1:
The patent applies curvature to the display panel, transforming it from a flat surface to a curved surface. This curvature allows the display area to extend further across the device body, increasing the screen-to-body ratio while maintaining a sleek, modern aesthetic that reduces the appearance of bezels and edges.
Solution Approach 2:
The patent introduces a curved surface dimension to the display panel, moving beyond the traditional two-dimensional flat plane. This dimensional change enables the display to wrap around or conform to the device body shape, maximizing the visible screen area relative to the device footprint.
2Area of moving object
If a curved display area is implemented, then the screen-to-body ratio increases, but the manufacturing precision requirements increase
Solution Approach 1:
The patent divides the display panel into distinct regions: a curved display area and a flat connection region. This segmentation allows each region to be manufactured and assembled separately with appropriate precision standards, reducing the overall manufacturing complexity compared to producing a fully curved display without such regional differentiation.
Solution Approach 2:
The patent introduces a connection region as an intermediary element between the curved display area and the flat housing or other components. This connection region serves as a transition zone that eases the integration of curved and flat elements, reducing the precision challenges at the interfaces between different structural components.
3Volume of moving object
If the connection region is positioned on the rear side of the display area, then internal space utilization increases, but the assembly complexity increases
Solution Approach 1:
The patent positions the connection region on the rear side of the display area, effectively nesting it within the device's internal volume rather than occupying external space. This nesting arrangement allows the connection region to be integrated into the device body's internal structure, maximizing space utilization while maintaining a compact overall form factor.
Solution Approach 2:
The patent designs the connection region to be pre-formed and pre-positioned on the rear side of the display panel during manufacturing. This preliminary positioning allows for simplified final assembly, where the connection region can be directly integrated with other device components without requiring complex real-time alignment or adjustment procedures.
