Abstract
A graphene display is provided. The graphene display includes a first graphene light-emitting unit and a second graphene light-emitting unit, which are stacked and overlapped, and a metal shield layer disposed between the first graphene light-emitting unit and the second graphene light-emitting unit. The graphene display is simple in structure, and the colors of the emitted light at the two sides will not change because of the electric field of the gate electrode pattern so as to have more stable color and color reproduction.
Claims1
A graphene display comprising:
- a first transparent substrate and a second transparent substrate, which are disposed oppositely;
- a first graphene light-emitting unit and a second graphene light-emitting unit, which are disposed in overlapping between the first transparent substrate and the second transparent substrate;
- and
- a first insulation layer, a metal shield layer and a second insulation layer, which are disposed in overlapping and located between the first graphene light-emitting unit and the second graphene light-emitting unit;
- wherein the first graphene light-emitting unit includes a first source electrode pattern and a first drain electrode pattern, which are disposed on the first transparent substrate and disposed separately with each other, a first graphene light-emitting pattern electrically connected with the first source electrode pattern and the first drain electrode pattern and located between the first source electrode pattern and the first drain electrode pattern, a third insulation layer set on and covering the first graphene light-emitting pattern, and a first gate electrode pattern disposed at a side of the third insulation layer away from the first transparent substrate;
- wherein the second graphene light-emitting unit includes a second source electrode pattern and a second drain electrode pattern, which are disposed on the second transparent substrate and disposed separately with each other, a second graphene light-emitting pattern electrically connected with the second source electrode pattern and the second drain electrode pattern and located between the second source electrode pattern and the second drain electrode pattern, a fourth insulation layer set on and covering the second graphene light-emitting pattern, and a second gate electrode pattern disposed at a side of the fourth insulation layer away from the second transparent substrate;
