Splicing Display Light Spacing for Reduced Gap Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional splicing display devices exhibit a visually obvious splicing slit due to a greater gap, which affects the display quality.
Innovation Solution
A splicing display device with at least two light emission substrates spliced together, featuring a first light emission region adjacent to the splicing gap, where the first interval between light emission units is greater than the second interval, ensuring the brightness of the splicing gap matches the adjacent regions, making it less noticeable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional splicing display devices use uniform intervals between light emission units, then the structure is simple and easy to manufacture, but the splicing gap becomes visually obvious and affects display quality
Solution Approach 1:
The patent applies local quality by differentiating the interval between light emission units in the first light emission region (adjacent to splicing gap) from those in the second light emission region. Specifically, the first interval is set greater than the second interval, creating a local variation that compensates for the splicing gap and reduces its visual prominence, thereby improving display quality without requiring complete structural redesign
2Manufacturing precision
If the first interval between light emission units in the first light emission region is increased to match the splicing gap brightness, then the splicing gap becomes less noticeable, but the overall display resolution may be affected
Solution Approach 1:
The patent implements local quality by creating a first light emission region with enlarged intervals adjacent to the splicing gap, while maintaining normal intervals in the second light emission region. This localized adjustment allows brightness matching at the splicing gap without compromising the overall display resolution, as only a specific local area is modified rather than the entire display structure

AI summary
The present application discloses a splicing display device including a first light emission region disposed adjacent to a splicing gap. The first light emission region is located between a second light emission region and the splicing gap. Along a first direction, a first interval is defined between adjacent two of the light emission units disposed in first light emission region, and a second interval is defined between adjacent two of the light emission units disposed in the second light emission region. The first interval is greater than second interval.
