▎ 摘 要
NOVELTY - The electrode (10) has a main portion which is provided with a graphene layer (101) and a doped layer (102). The doped layer is made of aluminum or zinc iodide. USE - Composite electrode of array substrate used for display device (all claimed). ADVANTAGE - The transmission speed of the carrier can be increased. The picture quality of the display device can be improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) an array substrate; (2) a display device; and (3) composite electrode preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of the composite electrode. Composite electrode (10) Graphene layer (101) Doped layer (102)
