Problems solved by technology

[0002] see figure 1 , shows an existing quantum dot film product, including two barrier films 1 and a quantum dot layer 2 formed between the two barrier films. This quantum dot film product is affected by the viscosity of the quantum dot coating and the thickness of the base film. Due to the influence of uniformity, uneven pressure is prone to occur during bonding, which makes the thickness of the quantum dot layer 2 difficult to control, which in turn causes uneven luminescence

Abstract

The invention provides a quantum dot film product which comprises a first barrier film, a second barrier film, a microstructure layer and a quantum dot layer, wherein the microstructure layer is of a prism structure formed by arranging a plurality of triangular prisms in parallel on the same plane; the height of the prism is between 5[mu]m and 150[mu]m; the vertex included angle is between 60 and 120 degrees. The microstructure layer produced on the barrier film is combined with the quantum dot layer, so that the thickness of the quantum dot layer can be effectively controlled, the microstructure layer can achieve a barrier effect, water vapor is prevented from permeating in from the periphery, and the durability is improved. Moreover, because the contact area of the quantum dot layer and the microstructure layer is enlarged, the adhesive power with the barrier film can be improved.

Description

technical field [0001] The invention relates to the technical field of conductive films, in particular to a quantum dot film product and a manufacturing method thereof. Background technique [0002] see figure 1 , shows an existing quantum dot film product, including two barrier films 1 and a quantum dot layer 2 formed between the two barrier films. This quantum dot film product is affected by the viscosity of the quantum dot coating and the thickness of the base film. Due to the influence of uniformity, uneven pressure is prone to occur during bonding, which makes it difficult to control the thickness of the quantum dot layer 2, and then causes uneven luminescence. Contents of the invention [0003] In view of the above, the present invention develops a quantum dot film product and a manufacturing method thereof that can effectively control the thickness of the quantum dot layer during production. [0004] A quantum dot film product, comprising a first barrier film, a s...
