Abstract

The invention relates to the technical field of display, in particular to a polarizer and a preparation method and a display device thereof. The polarizer comprises a transparent substrate, and an alignment film layer, a quantum rod layer and a protective layer which are formed on the surface on one side of the transparent substrate in sequence, wherein the quantum rod layer comprises a pluralityof quantum rods which are uniformly distributed and fixed on the alignment film layer. The polarizer is high in light transmittance, the power consumption of a backlight source can be reduced, the color gamut of the display device is improved, and the problem that the conventional backlight source is low in light utilization rate can be solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a polarizer, a preparation method thereof, and a display device. Background technique [0002] At present, in the TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) industry, the polarizers used for liquid crystal displays are usually absorbing polarizers, and the light emitted by the backlight will lose 1 / 2. After passing through the liquid crystal cell and the upper polarizer, the actual final transmittance is lower than 10%, which leads to the problem of low light utilization efficiency of the existing backlight source. Contents of the invention [0003] The invention provides a polarizer, a preparation method thereof, and a display device. The polarizer has high light transmittance, can reduce the power consumption of a backlight source and improve the color gamut of a display device, and can solve the problem of existing ba...
