Display Device Curling Support for Narrow-Bezel Bend Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in implementing a stable narrow bezel due to the lack of a structure that reinforces the stiffness of the bent area, leading to deformation and potential damage from external forces.
Innovation Solution
A display device design that incorporates a bending support with a curling shape to minimize deformation and enhance the rigidity of the panel bent area, using a first and second support plate with a bending support between them, where the outer surface of the curling shape contacts the inner curved surface of the bent panel area.

Engineering Contradiction Analysis
1Reliability
If a back frame is used to protect the display panel, then protection from external damage is improved, but deformation of the bent area occurs under impact
Solution Approach 1:
The support structure is divided into multiple segments: a first support plate, a second support plate, and a bending support positioned between them. This segmentation allows each component to perform its specific function - the first and second support plates provide overall support while the bending support specifically reinforces the bent area, preventing deformation under impact while maintaining protection.
Solution Approach 2:
The bending support is specifically positioned at the bent area of the display panel to provide localized reinforcement. This local quality approach ensures that the critical bent area, which is most susceptible to deformation, receives enhanced support without requiring the entire back frame to be overly rigid or complex.
2Ease of operation
If the bezel area is made thin to increase user immersion, then user immersion is improved, but the bent area becomes more susceptible to deformation
Solution Approach 1:
The bending support provides localized reinforcement specifically at the bent area, allowing the bezel to remain thin overall while the critical bent area receives enhanced support. This enables thin bezel design for user immersion without compromising the structural stability of the bent area.
Solution Approach 2:
The bending support is pre-installed in the support structure before the display panel is assembled, positioning it in advance to provide reinforcement at the bent area. This preliminary action ensures that the bent area is protected from deformation before any external impact occurs, enabling thin bezel design without compromising stability.
3Stability of the object's composition
If additional support structures are added to reinforce the bent area, then stability of the bent area is improved, but device complexity increases
Solution Approach 1:
The support structure is segmented into a first support plate, a second support plate, and a bending support. This segmentation allows the bending support to be a separate, focused component that provides targeted reinforcement at the bent area without requiring a complete redesign of the entire support structure, thus limiting the increase in complexity.
Solution Approach 2:
The bending support is positioned only at the bent area where reinforcement is needed, rather than adding support structures throughout the entire device. This local quality approach provides the necessary stability improvement while minimizing the overall increase in device complexity by focusing the additional structure only where required.

AI summary
A display device includes a display panel including a first area, a second area and a bent area. The device includes a first support plate disposed under the display panel and supporting the first area and the bent area of the display panel as well as a second support plate disposed on the display panel and supporting the second area of the display panel. The device further includes a bending support disposed between the first support plate and the second support plate, and supporting a bent portion of the bent area of the display panel. The bending support has a curling shape in the bent area of the display panel and an outermost surface of curved form of the curling shape is in contact with a curved inner surface of the bent portion of the display panel.
