Abstract

The invention discloses a quantum dot complex, a three-dimensional display element and a processing method of the quantum dot complex. The processing method of the quantum dot complex comprises the steps of: arranging a first transparent conducting layer, a quantum dot coating layer and a second transparent conducting layer sequentially on one side of a transparent substrate to form quantum dot units; bonding the plurality of quantum dot units; and finishing the bonded quantum dot units to obtain the quantum dot complex. According to the processing technology provided by the invention, the uniformity of all layers of light-emitting surfaces of a bulk material for three-dimensional display can be obviously improved, the light-emitting contrast, the transparency of the material and the depth resolution are improved, and the viewing angle of a three-dimensional image is increased.
