Display Panel Back Plate Grooves for Tighter Bending Radius
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels have a long bending radius, limiting the ability to achieve a narrow side frame, which is a challenge in the pursuit of thinner and more flexible display designs.
Innovation Solution
The implementation of a display panel with a buffer support structure comprising a first and second back plate, each with a groove, and a buffer support structure partially placed in the groove, reducing the distance between the plates and thus the bending radius.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the buffer support structure is placed between the first back plate and the second back plate without grooves, then the buffer effect is maintained, but the bending radius is too long and the side frame size is increased
Solution Approach 1:
The buffer support structure is nested into grooves formed on the first back plate and/or second back plate. This allows the buffer support structure to be partially or fully received within the grooves, reducing the overall distance between the back plates and minimizing the bending radius while maintaining structural integrity through the groove configuration.
Solution Approach 2:
The solution transitions from a linear arrangement where the buffer support structure spans the entire distance between back plates to a multi-dimensional configuration where the structure is recessed into grooves. This dimensional change allows the buffer support structure to occupy space within the back plates rather than only between them, effectively reducing the bending radius.
2Area of stationary object
If the distance between the first back plate and the second back plate is reduced to minimize bending radius, then the side frame size is reduced, but the buffer effect may be compromised
Solution Approach 1:
The grooves are strategically positioned and dimensioned to provide localized support for the buffer support structure. By configuring the grooves with specific depths and positions on the back plates, the buffer effect is maintained in critical areas while allowing overall compactness. The local quality of the groove structure ensures reliable buffering without requiring the entire buffer support structure to maintain a large distance from the back plates.

AI summary
Embodiments of the present disclosure are directed to a display panel and a display device. The display panel includes a display body, a first back plate, a second back plate and a buffer support structure. The buffer support structure is connected to the first back plate and the second back plate. At least one of the first back plate and the second back plate has a groove placed at one side facing the buffer support structure and the buffer support structure is partially placed in the groove. The distance between the first back plate and the second back plate is reduced and thus the bending radius of the bending part is reduced.
