▎ 摘　　要

NOVELTY - Conductive ink comprises conductive nano-metal and a graphene dispersion liquid including a graphene, where a lateral size of the graphene is between approximately 0.1 micron and approximately 1 micron, and the graphene has a weight percentage with respect to the conductive ink ranging from approximately 0.2 wt.% to approximately 0.5 wt.%. USE - Conductive ink. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for forming a pattern, which involves printing ink droplets of the conductive ink to-be-patterned region of a substrate, adjacent ink droplets at least partially overlapping with each other, controlling solvent in the ink droplets to evaporate to turn the ink droplets into annular conductive rings to form an initial electrode pattern in the to-be-patterned region, adjacent conductive rings intersecting each other and drying the initial electrode pattern to form a final electrode pattern; and (2) a display substrate, which comprises a final electrode pattern including a multiple of conductive rings intersecting each other, where a material of the conductive rings includes a nano-metal and a graphene, and line widths of the conductive rings are between approximately 2 mu m and approximately 7 mu m.
