Splicing Display Panel with Accommodation Grooves for Seamless Alignment

The patent introduces a new spatial dimension by creating an accommodation groove that extends vertically into the first substrate. This groove provides a recessed space where the third sub-display panel can be positioned, allowing its outer surface to align with the outer surfaces of the first and second sub-display panels. By utilizing the vertical dimension through the groove structure, the height difference problem is resolved while maintaining the seamless splicing effect.

The third sub-display panel is nested within the accommodation groove of the first substrate. The groove acts as a receiving structure that accommodates the third panel, effectively integrating it into the overall display assembly. This nesting approach allows the third panel to be positioned at the correct height relative to the other panels, eliminating visual differences from side views while maintaining seamless splicing.

Instead of increasing height in the vertical dimension, the patent uses the accommodation groove to create a recessed structure that allows the third sub-display panel to be positioned at the same outer surface level as the other panels. This dimensional approach resolves the conflict between structural simplicity and display quality by eliminating the need for height excess while maintaining easy assembly.

The accommodation groove serves as an intermediary structure between the first substrate and the third sub-display panel. It provides a standardized receiving space that facilitates precise positioning and alignment, acting as a mediator that ensures the third panel integrates seamlessly with the other panels without requiring complex adjustment mechanisms.
