Abstract

The invention relates to a quantum rod film for a backlight module of a liquid crystal display. The quantum rod film comprises a quantum rod layer containing a plurality of quantum rods with long axles arrayed in one direction, a prism micro-structural layer having first refraction rate and a plurality of stripped prisms arrayed in a parallel way, and a double-refraction layer covering the prism micro-structural layer having abnormal light refraction rate or normal refraction rate, wherein the prism micro-structural layer is arranged on a light-incident side of the quantum rod layer; and due to the difference between the first refraction rate of the prism micro-structural layer and the abnormal light refraction rate or normal refraction rate of the double-refraction layer, light-incident light of the long axle direction of the plurality of quantum rods are selectively paralleled and light-incident lights perpendicular to the long axle direction of the plurality of quantum rods are reflected and recovered to strengthen back light source utilization rate.

Description

technical field [0001] The invention relates to a quantum rod film used in a backlight module of a liquid crystal display, so that the liquid crystal display has better color gamut and light source utilization rate. Background technique [0002] The polarizer used in conventional liquid crystal displays generally adopts the absorbing polarizer. When the non-polarized light emitted by the backlight passes through the polarizer, the component in the direction of the absorption axis of the polarizer will be absorbed and cannot pass through. Therefore, the transmittance of the polarizer to the backlight source can only reach below 50% in theory, and after the light passes through the electrode layer of the liquid crystal panel, the color filter, the liquid crystal layer and the glass substrate, the user can actually see the brightness of the display , then only 10% or less of what is emitted by the backlight is left, so the utilization rate of the backlight is quite low, resulti...
