Abstract

The invention relates to a quantum dot thin film, a manufacturing method thereof and electronic equipment. The quantum dot thin film comprises a quantum dot material layer and multiple shielding pieces which are at least arranged at the edge of the quantum dot material layer and are vertical to the quantum dot material layer. According to a technical scheme of the invention, by arranging the shielding pieces at the edge of the quantum dot material layer, light, which is obliquely irradiated into the quantum dot material layer at a larger angle, of light rays coming from light sources can be shielded by the shielding pieces when the light is irradiated to the shielding pieces, so that the light cannot be irradiated out from the edge of the quantum dot material layer; only the light which is vertically irradiated into the quantum dot material layer can be successfully irradiated out, so that the light in corresponding color with the light sources can be prevented from being leaked from the edge of the quantum dot thin film, and a good viewing effect is ensured.

Description

technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a quantum dot film, a display device, a method for manufacturing a quantum dot film, and an electronic device. Background technique [0002] At present, in order to improve the color gamut of LCD screens, manufacturers generally use blue LEDs and quantum dot films as backlights. The blue light emitted by blue LEDs shines on the quantum dot film, exciting the quantum dots to emit light of different colors, making it into the display panel. mixed into white light. [0003] However, there are still some problems in the current quantum dot film. During use, the quantum dot film will be oxidized in contact with the air in the environment, and will be heated during the working process of the display screen, thereby accelerating the oxidation rate. Oxidation will lead to the failure of the quantum dot material in the quantum dot film. The invalid quantum dot material no ...
