Description

technical field [0001] The invention belongs to the field of optoelectronic technology, and in particular relates to a light emitting device, a display device, a manufacturing method of the display device and a power generating device. Background technique [0002] As a luminescent material, colloidal quantum dots (Quantum dots, QDs) have incomparable advantages over other luminescent materials, such as continuously adjustable luminous wavelength, ultra-high internal quantum efficiency, and excellent color purity. It has great application prospect. Due to the optical properties of the material, quantum dots are used in LCD panels to enhance the color gamut. At the same time, with the deepening of quantum dot electroluminescence (quantum dot light-emitting diode, QLED) research, more and more progress has been made in the industrialization process. [0003] At present, the quantum dot display technology on the market mainly uses the principle of quantum dot photoluminescenc...
