Seamless Multi-Panel LCD Splicing via Non-Display Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional large-scale LCD displays suffer from segmented images due to gaps between spliced panels, resulting in poor display performance.
Innovation Solution
A multi-panel display device is designed with first and second liquid crystal panels spaced apart, featuring non-display portions that extend from the edges of the display portions and are fixed together to eliminate gaps, along with a backlight module that includes transparent supporting pillars and light beam enhanced components for uniform lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple LCD panels are spliced together to create large-scale displays, then the display area is increased, but gaps appear between panels causing segmented images and poor display performance
Solution Approach 1:
The invention divides the display system into multiple LCD panels with extended non-display portions that overlap. Each panel is a separate unit that can be manufactured independently, yet when assembled, the extended non-display portions create overlapping regions that fill the gaps between panels, achieving seamless splicing while maintaining the benefits of modular manufacturing.
2Strength
If LCD panels are arranged with borders to protect the display area, then panel durability is improved, but gaps appear between adjacent panels
Solution Approach 1:
The invention extends the non-display portions beyond the traditional border area into the gap region between panels. This dimensional extension allows the non-display portions to serve dual purposes: maintaining panel structural integrity and simultaneously filling the visual gaps between panels, thereby eliminating display segmentation without compromising durability.
3Illumination intensity
If uniform lighting is provided across the entire display area, then display quality is improved, but the backlight module becomes more complex
Solution Approach 1:
The invention merges the backlight modules of adjacent panels within the overlapping non-display regions. By positioning backlight modules so that they illuminate both the display area and the extended non-display portions, the system achieves uniform lighting across the entire display surface while reducing the total number of separate backlight modules required, thereby simplifying the overall structure.

AI summary
A seamless splicing multi-panel display device includes a plurality of first liquid crystal panels being spaced apart, at least one second liquid crystal panel between every two the first liquid crystal panels, and a backlight module opposite to the first liquid crystal panel and the second liquid crystal panel. The first liquid crystal panel includes a first display portion and first non-display portions extending from edges of the first display portion. The second liquid crystal panel includes a second display portion and second non-display portions extending from edges of the second display portion. The second non-display portion is fixed on an area between the first display portion and the first non-display portion. In this way, the multi-panel display device realizes the seamless splicing display so as to enhance the display performance.
