Display Panel Positioning Structure to Prevent Sliding Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-scale display devices experience issues with display panels slipping and being damaged due to insufficient bonding area or force of adhesive layers, particularly in rotatable devices with heavy and large display panels.
Innovation Solution
A display device design incorporating positioning members and buffering members to secure the display panel, where the panel edge is close to but not in contact with the buffering members, preventing excessive sliding and collision during transportation or flipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If adhesive layer or adhesive tape is used to attach display panel to cover panel and frame, then assembly is simple, but bonding force is insufficient causing display panel to slide and be damaged
Solution Approach 1:
The patent introduces positioning members as intermediary components between the display panel and the frame/cover panel. These positioning members include positioning portions that engage with the display panel edges and connecting portions that attach to the frame, providing mechanical reinforcement to the adhesive bonding and preventing sliding during movement or flipping of the display device.
2Ease of manufacture
If adhesive layer is used to attach display panel, then assembly process is simple, but bonding area is insufficient for large-scale display panels
Solution Approach 1:
The patent divides the bonding system into multiple segments: adhesive layers provide base bonding, while multiple positioning members are distributed around the perimeter of the display panel. Each positioning member creates additional localized bonding points, effectively increasing the total bonding area without requiring a single large adhesive application that would be difficult to assemble.
3Ease of manufacture
If gap is left between display panel edges and frame for assembly tolerance, then assembly is easier, but display panel has insufficient support and may collide with frame
Solution Approach 1:
The positioning members act as intermediary structures that span the gap between the display panel edges and the frame. The positioning portions contact the display panel while the connecting portions attach to the frame, providing support and preventing collision while maintaining the necessary assembly tolerance gap.
4Area of moving object
If display panel is large-scale and heavy for rotatable devices, then display quality is improved, but panel sliding and damage risk increases
Solution Approach 1:
The patent uses multiple positioning members distributed around the perimeter of the large display panel rather than a single central support. This segmentation provides distributed support points that collectively bear the weight and prevent sliding of heavy large-scale panels during rotation and movement, improving stability without compromising the large display area.

AI summary
A display device includes a front cover, a positioning member, a buffering member, a display panel, a frame, a backlight film, and a back plate. The positioning member is fixed to the front cover. The buffering member is in contact with the positioning member. A panel edge of the display panel is close to but not in contact with the buffering member. The frame is attached and fixed to the display panel and is in contact with the buffering member and the positioning member. The backlight film is attached and fixed to the frame. The back plate is fixed to the frame and leans against the backlight film. A back plate sidewall of the back plate is positioned between the frame and the positioning member. An assembling method of the display device is also provided.
