Abstract
The invention discloses a reflector plate and a backlight module. The reflector plate comprises a base layer, a first metal layer, an adhesive layer, a second metal layer and a protective coating which are sequentially arranged in a stacked mode; the first metal layer is arranged on the end face, away from the incident side of the reflector plate, of the base layer, and the second metal layer is connected with the first metal layer in an adhesive mode through the adhesive layer; the thickness of the base layer is 38-38.5 [mu]m; the thickness of the first metal layer is 10-20nm, and the first metal layer is used for transmitting and reflecting incident light; the thickness of the adhesive layer is 3-8 microns, and the refractive index of the adhesive layer is n, n being greater than or equal to 1.337 and less than or equal to 1.48; the thickness of the second metal layer is 50-80nm, and the second metal layer is at least used for reflecting light penetrating through the first metal layer and the adhesive layer; and the thickness of the protective coating is 2-3 microns, and the protective coating is used for protecting the second metal layer. The reflector plate provided by the invention has high brightness and a good reflection effect.
Description
technical field [0001] The invention relates to the technical field of optical films, in particular to a reflection sheet and a backlight module. Background technique [0002] A backlight module is an important component of a liquid crystal display device. After the light source of the backlight module enters the light guide plate, the light source is provided upward to the LCD module, and the downward light enters the reflector, and then bounces back to the LCD module through the light guide plate, so it affects its quality and quality in the backlight module. A very important factor is the utilization rate of light reflection, that is, the brightness of the reflective film of the backlight module. [0003] In the related art, the reflective sheet using the metal layer as the reflective layer / reflective film is popular in the market because of its good reflection effect and high brightness of the reflective sheet. However, in the existing reflective sheet using a metal re...
