Backlight module with blue light blocking and reflecting film and liquid crystal display panel

Abstract

The invention discloses a backlight module with a blue light blocking and reflecting film and a liquid crystal display panel, and relates to the technical field of liquid crystal display, the module comprises a blue light preventing reflecting film which comprises a reflecting film base material and a blue light preventing coating which is fixed to the surface of one side of the reflecting film base material and has the inhibiting effect on light with the wavelength ranging from 380 nm to 500 nm. The blue light preventing coating on the reflecting film in the backlight module can effectively inhibit high-energy blue light with the wavelength of 380-500 nm in the light source, and harm of the blue light to human eyes is greatly reduced. Meanwhile, the reflecting film only suppresses 20 to 30 percent of leaked light, the visual effect of the display screen is not obviously influenced, the color gamut can be improved, the red quality can be improved, the basic function of the reflecting film is not influenced, and therefore the hidden danger that blue light generated in the light emitting process of an electronic screen or a light source harms human eyes in an existing backlight module containing a common reflecting film is fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a liquid crystal display panel containing a blue light blocking reflective film. Background technique [0002] The backlight module is one of the key components of the LCD panel. Its function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. The backlight module mainly includes a light source, a light guide plate, and an optical film, and the optical film mainly includes three types: a reflective film, a diffusion film, and a brightness enhancement film. [0003] The main function of the reflective film is to increase the reflectivity of the optical surface, reflect the light leaking out of the light guide plate efficiently and without loss, thereby reducing light loss, reducing power consumption, and improving the light saturation of the liquid crystal display surface. At present,...

Problems solved by technology

Under blue light, the retina will produce free radicals, which will lead to the decline of retinal pigment epithelial cells, which will lead to the lack of nutrients in light-sensitive cells, resulting in visual damage and visual damage, and these damages are irreversible

The backlight module with ordinary reflective film has no protection measures for the blue light generated by the electronic screen or the light source, exposing the human eye to the high-energy short-wave blue light, which poses a great hidden danger to human eye health

[0005] At present, although there are some protective devices such as anti-blue light eyes developed for the blue light in electronic screens or light sources on the market, they cannot block or suppress blue light in all directions, and have not fundamentally solved the damage caused by blue light to human eyes.
