▎ 摘　　要

NOVELTY - The baseplate has a first organic film layer (110) comprising a first graphene structure (111) and a first conductive structure (210) arranged on one side of the first organic film layer. The first conductive structure is electrically connected with first graphene structure. USE - Baseplate in an electronic device (device). ADVANTAGE - The substrate is prepared without film layer punching, simplifies the process flow, and improves the reliability of the device package. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing baseplate. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the baseplate. 110First organic film layer 111First graphene structure 210First conductive structure
