Spliced Display Panel Layout for High-Resolution Seam Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in eliminating seams during the splicing of high-resolution display screens, particularly in micro LED spliced screens, which affect visual quality.
Innovation Solution
A display panel design with a first and second display area, each containing pixel groups with driving and light-emitting assemblies arranged in a symmetrical configuration, allowing for increased negative tolerance and seamless splicing by utilizing the space between light-emitting assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If small-sized LED lamp beads with negative tolerance area are used to reduce seams, then splicing margin is increased, but resolution is reduced and the solution is only suitable for low-resolution spliced screens
Solution Approach 1:
The patent transitions from a single-row driving assembly layout to a multi-row driving assembly layout, utilizing the space dimension between light-emitting assemblies. By arranging driving assemblies in multiple rows and connecting them through signal lines, the patent achieves both seamless splicing and high resolution without relying on negative tolerance areas that would compromise display quality.
2Manufacturing precision
If driving assembly width is compressed to create negative tolerance area, then splicing seam is reduced, but device complexity increases and space is compressed
Solution Approach 1:
The patent segments the driving function across multiple driving assemblies arranged in different rows, rather than compressing a single driving assembly. Each driving assembly maintains its full width and functionality, while the segmented arrangement allows for proper spacing and signal distribution, reducing overall system complexity compared to compressed single-row designs.
Solution Approach 2:
The patent utilizes the vertical space dimension between light-emitting assemblies to position multiple driving assemblies, transforming a horizontal compression problem into a vertical distribution solution. This multi-row arrangement in the vertical dimension eliminates the need for horizontal compression and associated complexity.
3Area of stationary object
If light-emitting assemblies are positioned at outermost parts of display panel, then negative tolerance is increased, but seam elimination is not fully achieved
Solution Approach 1:
The patent introduces signal lines as intermediaries that extend beyond the outermost light-emitting assemblies to connect with adjacent display panels. These signal lines act as mediators that bridge the gap between panels, enabling seamless splicing while maintaining proper spacing and electrical connections without requiring excessive negative tolerance areas.

AI summary
A display panel, a spliced display module, and a method of manufacturing the spliced display module are provided. The display panel includes a first display area and a second display area located at a periphery of the first display area at least in a first direction. A first pixel group is arranged in the second display area and includes a first light-emitting assembly, a first driving assembly, a second driving assembly, and a second light-emitting assembly that are sequentially arranged in the first direction.
