Curved Display Extending Area Without Increasing Device Size
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with flat screens face a trade-off between increasing display area and maintaining portability, as enlarging the display size often results in increased device size, compromising portability, especially in mobile devices.
Innovation Solution
A mobile electronic device design featuring a curved display area that extends from a flat surface, with a smaller curved surface area than the flat area, and a case that protrudes over the edge, incorporating an external protective layer, opaque areas, and a panel module with display and non-display areas, where the non-display area is covered by an opaque layer to extend the display area without increasing the device's overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving 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 bending the flat display area along one or more sides to form a curved display area. This allows the display to extend into the curved region without increasing the overall device footprint, as the curved portion utilizes the vertical/bending dimension rather than expanding horizontally. The curved display area is formed by bending the flat display area, creating an extended display region that maintains device portability.
2Area of moving object
If the display area is extended using a curved surface, then the display area is extended without increasing device size, but the structural complexity increases due to additional components like opaque layers and support structures
Solution Approach 1:
The patent implements nesting by placing an opaque layer within the curved display area structure, specifically positioning it between the curved display area and the non-display area. This nested arrangement allows the opaque layer to serve multiple functions: it defines the boundary between display and non-display regions, provides structural support for the curved configuration, and prevents light leakage, all while being integrated within the existing display stack rather than adding external complexity.
Solution Approach 2:
The patent applies local quality by positioning the opaque layer specifically in the curved display area where it is needed to define the boundary and provide support, rather than applying it uniformly across the entire display. This localized approach allows the curved display area to have different optical and structural properties compared to the flat display area, optimizing each region for its specific function while minimizing overall structural complexity.
