Abstract

The invention relates to the technical field of optical thin film, in particular to a reflecting film applied in a backlight system with a liquid-crystal display as well as a manufacturing method thereof. In order to solve the problems of low brightness and low stiffness in the existing optical thin film, the invention provides a laminated composite reflecting film and a manufacturing method thereof. The reflecting film is of an ABA-type three-layer co-extrusion structure, wherein the layer B is provided with several stratified structures. Moreover, the layer A is prepared from, by weight, 78%-98.9% of matrix resin, 1%-20% of inorganic particle and 0.1%-2% of antistatic agent, meanwhile, the layer B is prepared from, by weight, 70%-90% of matrix resin, 5%-20% of incompatible resin and 5%-10% of white inorganic stuffing. The laminated composite reflecting film has the advantages of great brightness, good stiffness and less production cost due to less content of white inorganic pigments.

Description

technical field

[0001] The invention relates to the technical field of optical thin films, in particular to a high-efficiency reflective film applied to a liquid crystal display backlight source system and a manufacturing method thereof. Background technique

[0002] The reflective film is a part of the material of the LCD backlight module. It is located at the bottom of the backlight module and under the light guide plate. Its function is to reflect the light leaked through the light guide plate and return to the panel side. , to reduce light loss and increase brightness.

[0003] Liquid crystal display technology (LCD) is one of the most widely used display technologies at present, and will occupy the mainstream technology position in the field of flat panel display for a period of time. The liquid crystal molecule itself does not emit light. The image or character it displays is the result of its modulation of the light emitted by the backlight. The backlight is an impor...
