Abstract

The invention discloses a quantum dot film layer, a preparation method thereof and a display device. The quantum dot film layer comprises quantum dots, liquid crystal molecules and a chiral agent, andthe chiral agent enables the liquid crystal molecules to be arranged in a spiral array. The invention provides a quantum dot film layer, a preparation method thereof and a display device. Liquid crystal molecules and a chiral agent are doped into the quantum dot ink, liquid crystal molecules in a photopolymerized quantum dot film layer form a spiral structure by utilizing the optical rotation characteristic of a chiral agent, and quantum dot emergent light and a circular polarizer have the same polarization direction by utilizing the Bragg reflection characteristic of the spiral structure, sothat the quantum dot emergent light is prevented from being absorbed by the circular polarizer, and the luminous efficiency of the quantum dot display device is improved.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a quantum dot film layer, a preparation method thereof, and a display device. Background technique [0002] Quantum Dot (QD) is a semiconductor material that can realize light conversion, and is expected to play an important role in future display technology. QD-OLED technology, which combines the self-luminous characteristics of OLED devices and the characteristics of wide color gamut of quantum dots, is considered to be the next-generation display technology due to its advantages of thinness, flexibility, and high color gamut. QD-OLED devices generally have a double-layer structure, one side of which is a blue OLED, which acts as a backlight source, and the other side is a color film substrate containing quantum dot materials, which plays the role of light conversion. [0003] In order to reduce the reflection on the surface of the OLED display device, it is u...
