Graphene light emitting display and method of manufacturing the same

A method of manufacturing a graphene light emitting display, comprising the following steps:

• coating evenly a graphene oxide dispersion on a surface of the substrate with a thin film transistor formed thereon to form the graphene oxide thin film;
• providing a photomask to correspond to the graphene oxide thin film, so that light is radiated to the graphene oxide thin film through the photomask, to form a source electrode, a drain electrode and a graphene quantum dot layer of a graphene light emitting transistor;
• and
• forming an insulating layer and a water and oxygen isolating layer sequentially on a surface of a substrate with the graphene light emitting transistor formed thereon;
• wherein the photomask includes:
• a complete transparent part corresponding to the region in which the source electrode and the drain electrode are located;
• a light blocking part corresponding to the region in which the thin film transistor is located;
• and
• a semitransparent part corresponding to the region in which the graphene quantum dot layer is located.
