Abstract

The invention provides a preparation method of a nanoparticle film, the nanoparticle film and a display panel. According to the preparation method of the nano particle film, by utilizing the electrical characteristics of nano particles, a composite film structure is prepared through co-deposition of multiple nano materials with the same electrical properties, or a multi-layer film structure is obtained through sequential processing of the multiple nano materials with the same electrical properties; and by adjusting the electric field intensity, the stacking density of the nano material film can be adjusted, the thickness of the film can be accurately adjusted, then the conductivity, the refractive index and other performance of the film are affected, the light emitting performance of the display panel is enhanced, the technological process is reduced, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a preparation method of a nanoparticle film, a nanoparticle film and a display panel. Background technique [0002] Quantum dots (Quantum Dots, referred to as QD) are a typical class of nanomaterials, which have the characteristics of small size and high energy conversion efficiency, and are widely used in lighting, display technology, solar cells, optical switches, sensing and detection, etc. Very important application prospect. In addition, QD also has the characteristics of high brightness, narrow emission, adjustable luminous color, and good stability. Potential of new materials for display technology. [0003] At present, the QD patterning technologies mainly include inkjet printing and photolithography. The heating and UV curing of the photolithography process, as well as the flushing of the developer, will affect the stability of quantum dots; Mature and stable materia...
