Abstract

The invention discloses a display panel and a preparation method thereof. The display panel includes: a substrate; blue light LEDs that are arranged on the substrate in an array manner, and a gap is formed between every two adjacent blue light LEDs; a passivation layer that is arranged on the substrate and is filled in the gap of the blue light LED; a first black light resistor that is arranged onthe passivation layer; a light conversion layer that is arranged on the same layer with the first black light resistor; a plurality of quantum dot photoresist units that are arranged in the light conversion layer, and each quantum dot photoresist unit is correspondingly arranged on one blue light LED; and a scattering particle layer that is arranged on the same layer with the light conversion layer, and the scattering particle layer is provided with a plurality of scattering particle units which are correspondingly arranged on a blue light LED.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel and a manufacturing method thereof. Background technique [0002] As the core of a micro-display technology, quantum dot materials have attracted widespread attention because of their low cost and excellent optical properties. Compared with organic light-emitting materials, the advantages of quantum dot materials include: they can be synthesized by solution method, simple to prepare, low in cost, easy to control the spectrum, and have higher color purity. Therefore, quantum dots can be used for color conversion, replacing traditional color filters. [0003] Inorganic micro-LED devices have great application potential in the field of display technology because of their advantages such as the stability of luminescent materials, high brightness and pixel size can be reduced to nanoscale. Compared with organic light-emitting diodes (Organic Light-Em...
