Abstract

The invention discloses a quantum dot film with high luminous efficiency and a preparation process thereof. The preparation process of the quantum dot film with high luminous efficiency comprises the following steps: in parts by weight, providing 80-150 parts of adhesive, 1-10 parts of inorganic particles, 1-10 parts of quantum dot concentrate and 0.1-5 parts of photoinitiator Parts, mixed and configured as a quantum dot layer coating solution; the first barrier film and the second barrier film are provided, and the quantum dot layer coating solution is coated between the first barrier film and the second barrier film to obtain a quantum dot film Preform: performing multi-stage curing treatment on the quantum dot film preform to obtain the quantum dot film. The present invention adopts the matching method of photoinitiator and multi-stage curing process, optimizes the curing process of quantum dot film, improves the curing efficiency and reduces the impact on quantum dots, and finally improves the stability of the optical properties of the quantum dot film and the stability of the product production process. yield.

Description

technical field [0001] The invention relates to the technical field of quantum dot film preparation, in particular to a quantum dot film with high luminous efficiency and a preparation process thereof. Background technique [0002] With the development of semiconductor technology, various new materials are developing rapidly in various fields. As a typical existence of new nanomaterials, quantum dots play an increasingly important role in the field of optics and develop faster and faster [0003] Conventional LCD devices are equipped with a backlight unit that together converts the white backlight into the desired target display color. The colored light emitted by this traditional light-emitting device has limited performance and low luminous efficiency; while the traditional LCD device is equipped with a quantum dot film and combined with a blue light source, a display with high purity, high luminous efficiency, and high color gamut can be obtained. Improve the color disp...
