Light emitting device, electronic apparatus, control apparatus, and light emitting control method

A method for controlling a light emitting device, comprising:

• applying a voltage to a first electrode layer in the light emitting device, wherein the light emitting device comprising:
• a first electrode layer;
• an electroluminescent layer;
• and
• a nano antenna layer disposed in sequence, wherein the first electrode layer is configured to enable the electroluminescent layer to generate photons, and
• the nano antenna layer is configured to:
• when the photons are emitted to a surface of the nano antenna layer and close to the electroluminescent layer, generate a surface plasmon on the surface,
• wherein the nano antenna layer comprises a plurality of nano antenna units arranged in sequence, two adjacent nano antenna units are in contact with each other, and the plurality of nano antenna units comprise a tunable nano antenna unit, and
• the light emitting device further comprises a second electrode layer disposed on a side of the tunable nano antenna unit and far away from the electroluminescent layer.

A control apparatus, comprising:

• a processor, and
• a memory coupled to the processor to store instructions, which when executed by the processor, cause the processor to perform operations, the operations comprising:
• applying a voltage to a first electrode layer in a light emitting device, wherein the light emitting device comprising:
• a first electrode layer;
• an electroluminescent layer;
• and
• a nano antenna layer disposed in sequence, wherein the first electrode layer is configured to enable the electroluminescent layer to generate photons, and
• the nano antenna layer is configured to:
• when the photons are emitted to a surface of the nano antenna layer and close to the electroluminescent layer, generate a surface plasmon on the surface,
• wherein the nano antenna layer comprises a plurality of nano antenna units arranged in sequence, two adjacent nano antenna units are in contact with each other, and the plurality of nano antenna units comprise a tunable nano antenna unit, and
• the light emitting device further comprises a second electrode layer disposed on a side of the tunable nano antenna unit and far away from the electroluminescent layer.
