摘要: | An organic semiconductor infrared distance sensing apparatus and an organic infrared emitting apparatus thereof are disclosed. The organic semiconductor infrared distance sensing apparatus comprises an organic infrared emitting apparatus and an organic infrared receiving apparatus. The organic infrared emitting apparatus has a positive electrode layer and a negative electrode layer to form an electric field, and organic light emitting molecules are sandwiched between the two layers and correspond to the positive electrode layer and the negative electrode layer. Under a positive bias, a plurality of electrons and holes are respectively injected from electrodes and recombine with each other to emit photons. An infrared organic conversion layer absorbs and transfers the energy to infrared emitting molecules to emit infrared light. The organic infrared receiving apparatus receives the infrared light reflected by an obstacle to generate photocurrent which varies with distance, thereby sensing the distance between the obstacle and the apparatus. |
