Abstract

The invention provides a light emitting diode display and a preparation method thereof, and relates to the technical field of display. The light emitting diode display comprises a substrate, a first electrode, a first transmission layer, a luminescent layer, a second transmission layer, and a second electrode, wherein the first electrode is arranged above the substrate; the first transmission layer is arranged at one side, away from the substrate, of the first electrode; the first transmission layer covers the first electrode; the luminescent layer is arranged at one side, away from the substrate, of the first transmission layer; the luminescent layer covers the first transmission layer; the second transmission layer is arranged at one side, away from the substrate, of the luminescent layer; the second transmission layer covers or is tiled on the luminescent layer; and the second electrode is arranged at one side, away from the substrate, of the second transmission layer. The light emitting diode display and the preparation method thereof can improve the resolution of the display, and can guarantee uniformity of film thickness while preventing signal crosstalk.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a light emitting diode display and a preparation method thereof. Background technique [0002] With the rapid development of organic materials and quantum dot materials, organic electroluminescent devices (Organic Light Emitting Diode, OLED) and quantum dot electroluminescent devices (Quantum Dot Light Emitting Diode, QLED) also show a trend of rapid development. [0003] On the one hand, Active Matrix Organic Light Emitting Diode (AMOLED) has been recognized as a new generation display that is expected to replace Liquid Crystal Display (LCD), which usually adopts vacuum evaporation or printing technology to prepare. At present, the small molecule vacuum evaporation technology is relatively mature and industrialized, but the equipment investment and maintenance costs of this technology are high, and the material waste is serious. With the development of high-resolutio...
