1. A dual plate Organic Light-Emitting Field-Effect Transistor (OLET) display device comprising:
a first plate device comprising:
a first substrate;
a gate layer adjacent to the first substrate; and
a dielectric layer adjacent to the gate layer;
a second plate device connected to the first plate device, wherein the second plate device comprises:
a second substrate;
a source/drain layer adjacent to the second substrate; and
a stacked active organic layer adjacent to the source/drain layer,
wherein the first plate device and the second plate device are to be independently fabricated and joined together to position the stacked active organic layer adjacent to the dielectric layer, and
wherein the source/drain layer comprises:
a first side comprising a first planar surface contacting the second substrate; and
a second side opposite to the first side, wherein an entirety of the second side comprises a second planar surface contacting the stacked active organic layer.
