Curved Display Extending Area Without Increasing Device Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with flat screens face challenges in increasing display area without compromising portability, as enlarging the screen size leads to increased device size and reduced portability, especially in mobile devices.
Innovation Solution
A mobile electronic device design featuring a curved display area with a flat surface and a curved surface extending from it, incorporating an external transparent protective layer, an opaque area at the edge of the curved surface, and a panel module with display and non-display areas, where the opaque area is positioned to obscure the non-display area from view, maintaining a compact size while extending the display area.

Engineering Contradiction Analysis
1Area of stationary object
If the size of a flat display area is increased to extend the display area, then the display area is extended, but the overall size of the electronic device increases, degrading portability
Solution Approach 1:
The patent applies curvature to the display surface by extending the display area along a curved surface rather than a flat plane. The curved surface allows the display to wrap around edges or corners of the device, effectively increasing the display area without proportionally increasing the device's overall volume. This curvature principle enables the display to utilize three-dimensional space more efficiently.
Solution Approach 2:
The patent transitions from a two-dimensional flat display to a three-dimensional curved display that extends along the surface of the device. By utilizing the third dimension (depth/curvature), the display area is extended without requiring a proportional increase in the device's footprint or volume, thus maintaining portability while achieving larger display area.
2Area of stationary object
If a curved display is implemented to extend display area, then display area is extended, but the structural complexity increases
Solution Approach 1:
The patent divides the display structure into multiple components: a curved surface support structure, a curved surface part, and a flat surface part. This segmentation allows each component to be optimized independently and assembled together to form the complete curved display, reducing the overall structural complexity compared to a monolithic curved display design.
Solution Approach 2:
The patent employs a nested structure where the curved surface support structure provides the foundational framework, the curved surface part is positioned on and supported by this framework, and the flat surface part connects to the curved surface part. This nesting approach allows multiple functional layers to be integrated in a compact arrangement, managing structural complexity through hierarchical organization.
