Foldable Display Assembly With Core Plate Coupling for Narrow Bezels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses face challenges in minimizing the bezel area while ensuring robust connections, as increasing the viewable area reduces the bezel area, leading to weaker connections prone to failure, especially in foldable and bendable displays.
Innovation Solution
A display apparatus design featuring a core plate that supports the back surface of the display panel and allows it to be bent, coupled with a rear cover that covers the back surface of the core plate, where the coupling structure between the core plate and the rear cover is modified to minimize the bezel area and ensure strong connections without the need for separate fastening devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the viewable area is increased to achieve a bezel-less design, then the aesthetic appeal and user immersion are improved, but the connection area between components is reduced leading to weaker connections
Solution Approach 1:
The patent merges the connection function directly into the cover glass structure by forming protrusions that extend into the display panel. This integration eliminates the need for separate connection components, allowing minimal bezel area while maintaining strong connections through the integrated protrusion- groove coupling mechanism.
Solution Approach 2:
The connection is achieved by extending protrusions from the cover glass into the display panel in the depth dimension, rather than relying on lateral bezel area. This vertical integration allows the connection to occur within the thickness of the display assembly, preserving front view aesthetics while ensuring mechanical strength.
2Area of stationary object
If manual assembly methods are used to accommodate reduced bezel area, then the bezel-less design is achieved, but assembly errors increase due to reduced working space
Solution Approach 1:
The cover glass protrusions and display panel grooves are designed with self-aligning geometric features that guide automatic assembly equipment. The complementary shapes of protrusions and grooves provide inherent positioning, enabling precise assembly through automation rather than manual intervention, thus maintaining manufacturing precision while achieving minimal bezel area.
3Reliability
If separate fastening devices are used to ensure robust connections, then connection strength is improved, but the device complexity and bezel area increase
Solution Approach 1:
The connection function is merged into the cover glass itself by forming protrusions as an integral part of the cover glass structure. This eliminates the need for separate fastening devices such as screws or adhesives, reducing device complexity while maintaining robust connections through the direct structural coupling of protrusions and grooves.

AI summary
A display apparatus includes a display panel, a decoration film and a cover glass disposed on a front surface of the display panel, a core plate supporting a rear surface of the display panel and attached to the rear surface of the display panel, and a rear cover coupled to a rear surface of the core plate. The core plate has a protruding portion protruding toward the cover glass, the rear cover has a coupling portion coupled to the protruding portion so as to cover at least a portion of the protruding portion, and resin is applied to at least a portion of the coupling portion with the rear cover adhered to the decoration film or the cover glass via the resin.
