Embodiment Construction

[0022] In the backlight module of the present invention, an optical control film and a light wavelength conversion film are sequentially arranged above the light source, and an optical film is arranged above and / or below the light wavelength conversion film. Alternatively, the backlight module of the present invention may be provided with a lens and a light wavelength conversion film in sequence above the light source, and an optical film may be arranged above and / or below the light wavelength conversion film. The light wavelength conversion film can convert the light emitted by the light source into another light having a different wavelength, and two lights of different wavelengths are mixed with each other and then emitted out of the backlight module. Thereby, the type and arrangement of the optical film above and / or below the light wavelength conversion film can be used to adjust the light output effect of the backlight module (for example, the uniformity of light color). T...

Abstract

A backlight module provided by the present invention comprises a light source, an optical wavelength conversion film, a first group of optical films and a second group of optical films. The light source is applicable to emit a first ray of light. The optical wavelength conversion film is applicable to convert the first ray of light to a second ray of light with different wavelengths. The first group of optical films is configured between the light source and the optical wavelength conversion film. The optical wavelength conversion film is located between the first group of optical films and the second group of optical films, wherein the ratio of the penetration rate of the second group of the optical films with respect to the second ray of light and the penetration rate of the first group of the optical films with respect to the first ray of light is not less than 45%. Thereby, the backlight module is provided with uniform glaring colors.

Description

【Technical Field】 [0001] The invention relates to a backlight module. 【Background technique】 [0002] In recent years, with the widespread use of electronic products, display panels for providing display functions in electronic products have become the focus of attention of designers. There are many types of display panels, which can be selected according to the design of electronic products. Among them, some types of display panels do not have a light-emitting function, and a backlight module (backlight module) needs to be provided below to provide a light source to achieve the display function. [0003] The backlight module usually includes an assembly frame, a light source, and a light guide plate. According to the relative relationship between the light source and the light guide plate, the backlight module can be divided into a direct type backlight module and an edge type backlight module. Taking the direct-lit backlight module as an example, the light source and the light...
