Embodiment 1

[0027] figure 1 is a schematic structural diagram of a backlight module provided by an embodiment of the present invention, such as figure 1 As shown, the backlight module includes a color conversion layer 10 and a light source 20. The light source 20 is a monochromatic light source. In this embodiment, the light source 20 emits blue light. The anti-reflection composite film 30 is arranged on the side of the color conversion layer 10 away from the light source 20; the anti-reflection and anti-reflection composite film 30 is configured to perform anti-reflection on the light entering the anti-reflection and anti-reflection composite film 30 in the first preset angle range , and / or enhance and reflect the light entering the anti-reflection and anti-reflection composite film 30 in the second preset angle range.

[0028] Wherein, the color conversion layer 10 can be used to convert a monochromatic light source into white light obtained by mixing red light, green light and blue li...

Abstract

Embodiments of the present invention provide a backlight module and a display device, which relate to the field of display technology. Wherein, the backlight module includes: a color conversion layer and a light source, and the backlight module also includes: an anti-reflection and anti-reflection composite film, and the anti-reflection and anti-reflection composite film is arranged on a side of the color conversion layer far away from the light source side; the anti-reflection and anti-reflection composite film is configured to perform anti-reflection on the light incident on the anti-reflection and anti-reflection composite film in the first preset angle range, and / or for the light incident in the second preset angle range The light of the antireflection and antireflection composite film is enhanced and reflected. In the present invention, on the one hand, the anti-reflection and anti-reflection composite film can reduce the blue light conversion rate of light entering the anti-reflection and anti-reflection composite film in the first preset angle range, and improve the yellowish phenomenon that occurs when the screen is displayed; on the other hand The blue light conversion rate of light entering the anti-reflection and anti-reflection composite film in the second preset angle range can be improved, and the bluish phenomenon that occurs when the picture is displayed is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] At present, a display device usually includes a backlight module, and the backlight module is used to supply sufficient brightness and a light source with uniform distribution, so that the display device can normally display images. [0003] Generally, the color conversion layer in the backlight module can perform color conversion on the blue light emitted from the light source, so as to obtain white light which is mixed with red light, green light and blue light. Among them, since the corresponding optical path of the blue light emitted from the light source passing through the color conversion layer obliquely is smaller than the corresponding optical path when passing through the color conversion layer vertically, the blue light entering the color conversion layer at a large angle will be more color...
