Display Panel Threaded Alignment Assembly for Minimal Step Difference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies, such as LCD and AMOLED, face challenges with response time, flexibility, lifespan, and yield, while semiconductor LEDs offer advantages like long lifespan and low power consumption but require improved assembly methods to minimize step differences between display panels.
Innovation Solution
A display assembly system using a display panel with a nut, frame, outer adjusting member, and inner fixing member, where the outer adjusting member and inner fixing member are threaded to align and space the display panels, minimizing step differences through a sensing mechanism and adjustable assembly height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional assembly methods are used for display panels, then assembly is simpler, but step differences between panels increase
Solution Approach 1:
The outer adjusting member includes a rotating body that can rotate around the fastening hole, enabling dynamic adjustment of the display panel's position. This rotation mechanism allows for real-time correction of step differences and alignment issues during assembly, transforming a static assembly process into a dynamic one that adapts to manufacturing variations.
Solution Approach 2:
The assembly structure is divided into multiple independent components: the frame, the outer adjusting member (with hollow portion and rotating body), the inner fixing member, and the nut. This segmentation allows each component to perform its specific function independently, making the overall system more manageable and precise in controlling panel alignment.
2Manufacturing precision
If multiple assembly steps are used to adjust panel alignment, then alignment precision improves, but assembly time increases
Solution Approach 1:
The outer adjusting member is pre-assembled with the frame before the display panel is installed. This preliminary preparation allows the adjustment mechanism to be in place and ready for immediate use, eliminating the need for complex post-installation adjustments and reducing overall assembly time.
Solution Approach 2:
The rotating body can be adjusted during the assembly process itself, allowing for real-time alignment correction without requiring separate adjustment steps. This dynamic adjustment capability integrates alignment correction into the primary assembly operation, reducing total assembly time.
3Area of stationary object
If display panels are assembled closely together, then device size is reduced, but step differences between panels become more noticeable
Solution Approach 1:
The outer adjusting member provides dynamic adjustment capability that allows panels to be positioned precisely relative to each other even when closely spaced. The rotation mechanism enables fine-tuning of panel positions to eliminate visible step differences while maintaining compact device dimensions.
Solution Approach 2:
The adjustment mechanism is localized at each fastening position, allowing individual panels to be adjusted independently. This local adjustment capability ensures that each panel can be precisely aligned with its neighbors, maintaining flatness across the entire display surface while keeping the device compact.

AI summary
Discussed is a display that can include a display panel, a nut fixed to a rear surface of the display panel, a frame including a female thread formed in a fastening hole facing the nut, an outer adjusting member including a hollow portion formed therein having a male thread that is screwed with the female thread of the fastening hole, and an outer head portion protruding out of the hollow portion. An inner fixing member can be further included and can include a thread portion passing through the hollow portion and screwed with the nut, and an inner head portion seated on the outer head portion or the hollow portion.
