Curved Display Panel Guide Unit Bezel Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with curved portions tend to become flat due to restoration forces, and existing designs often have a significant bezel size that obstructs image display areas.
Innovation Solution
A display device comprising a curved display panel with a guide unit and a casing unit, where the guide unit, made of materials like metal, plastic, or organic/inorganic composite materials, supports the curved panel to maintain its shape, and the casing unit covers at least a portion of the curved area, reducing the bezel size by allowing image display in uncovered areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a curved display panel is used to improve aesthetic appeal and reduce bezel size, then the display area is increased and design flexibility is improved, but the curved portion tends to become flat due to restoration forces
Solution Approach 1:
The guide unit is pre-formed with a curved shape that matches the desired display panel curvature. This preliminary curved structure is positioned against the display panel before final assembly, providing immediate structural support that prevents the panel from returning to a flat state. The guide unit's pre-established geometry acts as a mechanical constraint that maintains the curved configuration.
Solution Approach 2:
The guide unit serves as an intermediary component between the display panel and the casing unit. It mediates the structural support function by transferring loads and constraints from the casing to the display panel, thereby maintaining the curved shape without requiring the display panel itself to have sufficient rigidity to resist restoration forces.
2Stability of the object's composition
If the casing unit covers the entire curved area to maintain shape, then structural support is improved, but the bezel size increases and display area is reduced
Solution Approach 1:
The guide unit provides localized structural support specifically at the curved portion of the display panel where shape maintenance is critical. The casing unit is designed to cover only specific regions rather than the entire curved area, allowing display content to be shown in previously bezel-covered regions while the guide unit locally maintains the curved geometry through targeted support.
Solution Approach 2:
The support structure is segmented into distinct functional components: the guide unit that specifically maintains the curved shape, and the casing unit that provides partial coverage and additional support. This segmentation allows each component to perform its specific function optimally without the need for complete coverage, thereby maximizing display area while maintaining structural integrity.

AI summary
A display device includes a display panel having a curved area and a substantially flat area, a guide unit including a curved area and a first area, and a casing unit. The first area of the display panel extends from a first end of the curved area of the display panel. The curved area of the guide unit supports the curved area of the display panel. The first area of the guide unit supports the first area of the display panel. The casing unit covers at least a portion of the curved area of the display panel.
