Abstract
A quantum dot film, a manufacturing method thereof, and a display panel are provided. In the quantum dot film, grooves are defined on a first protective layer and/or a second protective layer corresponding to each quantum dot region. Quantum dot layers are filled in the grooves to form protruding structures. Therefore, the quantum dot layers of each quantum dot region are made to have height differences to reduce optical path differences of different lights at different angles passing through the quantum dot layers to ease a problem of uneven display existing in display products.

A quantum dot film divided into a plurality of quantum dot regions, comprising:
- quantum dot layers, wherein quantum dots are disposed on the quantum dot layers;
- and
- a first protective layer and a second protective layer disposed on two opposite sides of the quantum dot layers;
- wherein the quantum dot layers of each of the quantum dot regions have height differences to reduce optical path differences between lights of different incident angles passing through the quantum dot layers.
A display panel, comprising a quantum dot film and a plurality of excited light sources, wherein the quantum dot film is divided into a plurality of quantum dot regions, each of the quantum dot regions corresponds to one of the excited light sources, and the quantum dot film comprises:
- quantum dot layers, wherein quantum dots are disposed on the quantum dot layers;
- and
- a first protective layer and a second protective layer disposed on two opposite sides of the quantum dot layers;
- wherein the quantum dot layers of each of the quantum dot regions have height differences to reduce optical path differences between lights of different incident angles passing through the quantum dot layers.
A manufacturing method of a quantum dot film, comprising:
- manufacturing a first protective layer, wherein manufacturing the first protective layer comprises providing a base material layer and manufacturing a barrier layer on the base material layer to form the first protective layer;
- patterning the first protective layer to form first grooves;
- manufacturing quantum dot layers, wherein manufacturing the quantum dot layers comprises manufacturing the quantum dot layers on the first protective layer and the first grooves to make the quantum dot layers form protruding structures;
- and
- manufacturing a second protective layer on the quantum dot layers to form the quantum dot film.
