Curved Display Frame with Adjustable Hemming Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies, particularly OLED displays, face challenges in securely fixing and aligning curved display assemblies due to differences in deformation capacities between the display panel and the backplate, leading to misalignment issues during bending.
Innovation Solution
A frame design incorporating a support assembly, hemming brackets, and detachable fixing structures allows for adjustable positioning of the hemming brackets relative to the support assembly, enabling precise alignment and secure fixation of the curved display assembly, thereby minimizing misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display panel and backplate are fixed together during bending, then the curved display assembly can be formed, but misalignment occurs due to different deformation capacities
Solution Approach 1:
The frame is divided into multiple independent components: support assembly, hemming brackets, and detachable fixing structures. This segmentation allows each component to be optimized independently and assembled with adjustable positioning to accommodate differential deformation between the display panel and backplate during bending, preventing misalignment.
Solution Approach 2:
The detachable fixing structures enable dynamic adjustment of the frame's rigidity. During the bending process, the fixing structures can be detached or adjusted to allow differential deformation between the display panel and backplate, then resecured in the curved configuration to maintain precise alignment in the final assembled state.
2Stability of the object's composition
If the hemming brackets are rigidly fixed to the support assembly, then structural stability is improved, but alignment adjustment capability is lost
Solution Approach 1:
The detachable fixing structures provide a dynamic connection between the hemming brackets and support assembly. They can be detached to allow position adjustment during assembly and curvature adaptation, then secured to provide rigid structural stability in the final assembled state, achieving both adjustability and stability.
Solution Approach 2:
The fixing structures allow change in the connection state between hemming brackets and support assembly - from detached (allowing position adjustment) to secured (providing structural stability). This parameter change enables the frame to adapt to different assembly stages and maintain both adjustability and stability as needed.

AI summary
A display apparatus includes a frame and a display assembly. The frame includes a support assembly extending in a first direction, at least two hemming brackets, and at least two detachable fixing structures. The at least two hemming brackets are respectively disposed at both sides of the support assembly in the first direction, and each of the both sides is provided with at least one of the at least two hemming brackets. Each hemming bracket extends in a second direction. An end of the hemming bracket away from the support assembly is a flanged portion. The hemming bracket is fixed to a corresponding end of the support assembly through at least one detachable fixing structure. The display assembly includes a display panel and a backplate disposed on the support assembly. The at least two hemming brackets are located at two edges of the display assembly in the first direction.
