Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with overlapping display panels face challenges in achieving accurate alignment, leading to degraded display quality due to insufficient alignment accuracy caused by gaps between panels and guides.
Innovation Solution
A display device with a frame system that includes reference and position adjustment spacers, where the spacers are designed to securely attach to the frame unit, allowing for precise positioning and adjustment of display panels to enhance alignment accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an L-shaped guide is used to mount the display panel on a frame, then the display panel can be mounted, but a gap is generated between the display panel and the guide, resulting in insufficient alignment accuracy
Solution Approach 1:
The patent introduces spacers as intermediary elements between the frame and display panels. These spacers act as mediators that precisely position the panels while eliminating gaps. The spacers include reference spacers for positioning and adjustment spacers for fine-tuning, thereby achieving high alignment accuracy without complex mounting structures.
Solution Approach 2:
The mounting structure is segmented into distinct functional components: reference spacers for initial positioning, adjustment spacers for fine-tuning, and fixing mechanisms. This segmentation allows each component to perform its specific function optimally, with reference spacers providing stable positioning and adjustment spacers enabling precise alignment, thereby solving the gap problem without overall structural complexity.
2Manufacturing precision
If pixels of the front-side display panel deviate from corresponding pixels of the rear-side display panel, then the device structure becomes simpler, but display quality degrades
Solution Approach 1:
The patent incorporates adjustment spacers that enable feedback-based alignment. The spacers can be adjusted to compensate for deviations between front-side and rear-side display panel pixels. By providing mechanical feedback through the adjustment mechanism, the system achieves precise pixel alignment, ensuring high display quality while maintaining a relatively simple overall structure.
Solution Approach 2:
The mounting structure transitions from a static fixed-position design to a dynamic adjustable design. The adjustment spacers allow the display panels to be positioned dynamically during assembly and potentially adjusted later. This dynamic capability ensures that pixel alignment accuracy is achieved even if initial positioning has deviations, thereby maintaining high display quality.

AI summary
A display device, in which a plurality of display panels overlap each other and an image is displayed on each of the display panels, comprises a first frame supporting the plurality of display panels. The first frame includes a frame-shaped frame unit on which the plurality of display panels are placed, and a plurality of spacers attached to the frame unit. The plurality of spacers include at least one reference spacer fixed to the frame unit and at least one position adjustment spacer adjustably attached to the frame unit. An outer peripheral end of each of the plurality of display panels is fixed while pushed against the reference spacer and the position adjustment spacer.
