Splicing Display Device With Vacuum-Fixed Second Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The flatness of the splicing position in large-size display screens is affected by the arrangement of light-emitting diode strips on liquid crystal display panels, which impacts the display performance.
Innovation Solution
A splicing display device with vacuum suction components and a vacuuming unit is used to attach a second display unit to the non-display areas of adjacent first display units, ensuring a flat and secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If light-emitting diode strips are fixed directly on the liquid crystal display panel, then the splicing position can be connected and spliced, but the flatness of the splicing position deteriorates
Solution Approach 1:
The backlight module is divided into separate components: a backplane with side plates forming a cavity, and a light-emitting diode strip. This segmentation allows the light-emitting diode strip to be positioned within the cavity rather than directly on the display panel, resolving the conflict between splicing connection and flatness.
Solution Approach 2:
The side plate and cavity structure act as an intermediary between the light-emitting diode strip and the liquid crystal display panel. The cavity receives and positions the light-emitting diode strip, while the side plate provides structural support and maintains flatness at the splicing position, eliminating direct contact between the LED strip and the display panel surface.
2Manufacturing precision
If the second display unit is attached to the splicing position, then display performance is improved, but the structural complexity increases
Solution Approach 1:
The fixing component is merged with the backplane structure of the backlight module. The side plate forms an integrated cavity that both holds the light-emitting diode strip and provides the fixing function for the second display unit, eliminating the need for separate fixing structures and reducing overall device complexity.
Solution Approach 2:
The side plate serves multiple functions: it forms the cavity to hold the light-emitting diode strip, provides structural support for the backlight module, and acts as the fixing component for the second display unit. This multi-functionality reduces the number of separate components needed while maintaining display performance.

AI summary
A splicing display device is provided. The splicing display device includes at least two first display units and a second display unit. The first display units are spliced and connected. Each of the first display units includes a non-display area. The second display unit is disposed on a light-emitting side of the first display units, and attached and fixed to a splicing position of the non-display areas of the two adjacent first display units.
