Abstract

The invention relates to the technical field of photoelectric devices, and particularly provides a light emitting device, a display device and a method of manufacturing the display device. The light emitting device comprises a light source, a substrate and a light emitting unit, wherein the substrate is arranged between the light source and the light emitting unit, the light emitting unit comprises an anode, a light emitting layer and a cathode, and the light emitting layer is arranged between the anode and the cathode; and a first transmission layer is arranged between the light emitting layer and the cathode. The light emitting device provided by the invention can realize effective adjustment of light emitting brightness so as to obtain light emitting effects with different brightness requirements. According to the light emitting display device based on the light emitting device, the brightness of each pixel unit can be adjusted, so that effective light emitting display is formed, and the structure and application of the light emitting display device are greatly expanded.

Description

technical field [0001] The invention belongs to the technical field of optoelectronic devices, and in particular relates to a light emitting device, a display device and a manufacturing method of the display 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 photoluminescence. The quantum dot m...
