AI Technical Summary
The luminous brightness and luminous efficiency of existing organic light-emitting transistors (OLEDs) are difficult to improve, and their high structural complexity makes it difficult to achieve mixed color luminous effects.
The light-emitting transistor adopts a dual-electrode layer and dual-emitting layer structure. The light-emitting current is controlled by the gate voltage. Combined with the design of light-transmitting materials and insulating layers, the two light-emitting layers can emit light independently or alternately, simplifying the structure and improving the luminous efficiency.
It improves the integration and energy utilization efficiency of light-emitting devices, reduces the exciton quenching probability, and achieves mixed light emission effects of multiple colors or increases the intensity of a single color light.
