• When viewing the mini‐LED display screen from a large angle, the seam appearing at the edge of the module can disrupt the uniformity of the entire screen's bright state. This paper studies the formation mechanism of bright and dark seam and color seam from the perspectives of spatial frequency and packaging structure, derives the formula for spatial frequency, analyzes the optical path at the splicing position, and designs a reasonable packaging film structure to solve the color seam. The formation of splicing seam is mainly related to spatial frequency changes and packaging structure. Calculate the spatial frequency and combine it with the contrast sensitivity function curve to determine the seam state. In the case of no spatial frequency changes, a reasonable packaging structure was designed to solve the color seam by analyzing the optical path.
