Spliced Display Panel Layout for Minimal Micro-LED Seams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spliced Micro-LED display devices face the challenge of larger seams due to the need for connecting terminals on both the top and bottom sides of the display panel, leading to issues like dark lines and increased seam size during display.
Innovation Solution
The solution involves integrating gate driving units within the pixel units of each display panel, allowing data and scan terminals to be placed on the same side, eliminating the need for binding scan chips and reducing side wirings, and arranging the terminal area of one panel to correspond with the display area of another to minimize seams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connecting terminals are set on both the top and bottom sides of the display panel to conduct front signals to the back, then the driving circuit can be connected to the display area, but the seam size at splicing joints increases
Solution Approach 1:
The patent merges the data terminals and scan terminals onto the same side of the display panel (both top or both bottom), consolidating what were previously separated terminal areas. This allows both types of connections to be made at one location rather than requiring separate terminal areas on opposite sides, thereby reducing the overall seam size while maintaining reliable electrical connections to the display area.
2Reliability
If terminal areas are set on both sides of the display panel, then electrical connections can be established, but the border width increases preventing seamless splicing
Solution Approach 1:
The patent combines both data terminals and scan terminals on the same side of the display panel, merging what were previously separate terminal areas into a single consolidated region. This reduces the total border area required while ensuring that all necessary electrical connections are established through this unified terminal area, enabling seamless splicing of multiple display panels.
3Ease of manufacture
If gate connecting terminals and data connecting terminals are placed on adjacent sides, then manufacturing is simplified, but signal interference occurs between terminals at the junction
Solution Approach 1:
The patent merges gate connecting terminals and data connecting terminals onto the same side of the display panel rather than placing them on adjacent sides. This consolidation maintains manufacturing simplicity while increasing the distance between terminals of different types, thereby reducing electromagnetic signal interference at the junction while still allowing for straightforward assembly processes.

AI summary
A spliced display screen and a spliced display device are provided. The spliced display screen includes gate driving units arranged within pixel units to drive these pixel units, eliminating the need for binding scan chips. This approach can reduce the number of side wirings and binding terminals, thereby improving the yield of the spliced display screen. Additionally, by placing both scan terminals and data terminals on the same side of the display area, the display panel is designed with connecting terminals on only one side, effectively eliminating a border on one side of a display panel. Moreover, a terminal area of one display panel is arranged corresponding to the display area of another display panel, and therefore, a splicing seam is minimized or even eliminated.
