Abstract

Provided are a light concentrating film (10) and manufacturing method thereof, backlight module and liquid crystal display panel, capable of improving light source utilization ratio and reducing the diffusion angle of the light incident to the liquid crystal display panel, thus improving the brightness of the liquid crystal display panel; the light concentrating film (10) comprises a panel formed by alternately laminating at least one layer of first material (11) and at least one layer of second material (12); the first layer of material (11) is an anisotropic material; and in at least one direction of the panel plane, the refractive index of the at least one layer of first material (11) is equal to that of the at least one layer of second material (12); and in the direction perpendicular to the panel, the refractive index of the at least one layer of first material (11) is not equal to that of the at least one layer of second material (12).

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a light-gathering film, a backlight module and a liquid crystal display panel. Background technique [0002] The backlight module of the liquid crystal display panel in the prior art is usually composed of a light source, a light guide plate, an optical film and other parts. In order to ensure the quality of the display picture, the backlight module should have the properties of high brightness, uniform light emission, large lighting angle, light weight and thin thickness. [0003] In the backlight module in the prior art, the optical film is usually designed in many ways to ensure the performance of the backlight module, such as setting a prism film on the light guide plate, and the prism film is used to gather the light of the backlight at a smaller angle Inject within the range, or use reflective polarized brightness enhancement film, which uses two kinds of ma...
