Abstract
A light conversion film for a backlight module, a backlight module and a display device are disclosed. The backlight module includes a light source that emits at least a first light; a light conversion film that receives the first light, converts the first light into a second light and emits the second light such that a light emission angle of the backlight module is greater than 120 degrees and a color temperature is less than 15000. The present invention can increase a brightness viewing angle to reach 120 degrees. Besides, the light conversion film has a higher light excitation efficiency, capable of decreasing the color temperature of the backlight module, and enhances the display effect.
