▎ 摘　　要

NOVELTY - The device has a substrate formed with a cathode electrode. Graphene pieces (30a, 30b) are fixed in the substrate. Insulating layers (40a, 40b) are formed at an upper part of the graphene pieces. A source electrode is formed at the upper part of the graphene pieces. Gate electrodes are formed in a drain electrode. A silicon layer (21) is formed in the substrate. A silicon dioxide layer (22) is formed in the silicon layer. Metal electrode layers (50a, 50b) are made of aluminum, copper, gold or silver. The insulating layers are made of metal oxide or teflon group heat polymer. USE - Graphene variable energy visible light emission penetration optical device for a field emission display and an organic light-emitting display. ADVANTAGE - The device controls the luminous energy, provides excellent visible light, manufactures the visible light emission device with large size in a simple manner, and reduces the manufacturing cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing a graphene variable energy visible light emission penetration optical device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a graphene variable energy visible light emission penetration optical device.
