Patent number: 10784458Abstract: An organic light-emitting diode including an anode, a cathode, and a luminescent layered structure disposed between the anode and the cathode. The luminescent layered structure has a luminescent layer, a sensitizer layer and a guiding material. The luminescent-layer singlet state is two times higher than the luminescent-layer triplet state. The sensitizer layer has a sensitizer-layer triplet state between the luminescent-layer singlet state and the luminescent-layer triplet state. The guiding material has a guiding-material triplet state between the sensitizer-layer singlet state and the sensitizer-layer triplet state. The energy of molecules at the sensitizer-layer singlet state is transferred to the guiding-material triplet state and then to the sensitizer-layer triplet state, which is then transferred to the luminescent-layer triplet state and triggers triplet-triplet annihilation upconversion in the luminescent layer such that the luminescent layer emits light of a first color.Type: GrantFiled: March 15, 2019Date of Patent: September 22, 2020Assignees: YUAN ZE UNIVERSITY, NICHEM FINE TECHNOLOGY CO., LTD., WISECHIP SEMICONDUCTOR INC., TETRAHEDRON TECHNOLOGY CORPORATION, SHINE MATERIALS TECHNOLOGY CO., LTD.Inventors: Jiun-Haw Lee, Tien-Lung Chiu, Chia-Hsun Chen, Pei-Hsi Lee

Patent number: 10700303Abstract: An organic light-emitting diode including an anode, a cathode, and a luminescent layered structure is provided. The luminescent layered structure is disposed between the anode and the cathode. The luminescent layered structure has a luminescent layer and a sensitizer layer. The luminescent layer has a luminescent-layer ground state, a luminescent-layer singlet state and a luminescent-layer triplet state, in which two times of the luminescent-layer triplet state is higher than the luminescent-layer singlet state. The sensitizer layer has a sensitizer-layer triplet state, which is between the luminescent-layer singlet state and the luminescent-layer triplet state. The molecules of the sensitizer layer at the sensitizer layer triplet layer transfers energy to the molecules of the luminescent layer at the luminescent-layer triplet state and triggers triplet-triplet annihilation upconversion in the luminescent layer such that the luminescent layer emits light of a first color.Type: GrantFiled: March 14, 2019Date of Patent: June 30, 2020Assignees: YUAN ZE UNIVERSITY, NICHEM FINE TECHNOLOGY CO, LTD., WISECHIP SEMICONDUCTOR INC., TETRAHEDRON TECHNOLOGY CORPORATION, SHINE MATERIALS TECHNOLOGY CO., LTD.Inventors: Jiun-Haw Lee, Tien-Lung Chiu, Chia-Hsun Chen, Pei-Hsi Lee
