Abstract
The present application discloses a backlight module and a display device, the backlight module including a light source for emitting at least a first light; at least two sheets of light conversion films, wherein at least one sheet of light conversion films receives the first light and converts the light into at least a second light to emit, and makes the light emitting angle of the backlight module matching the wide viewing angle display requirements. It can increase the light emitting angle of the backlight module and achieve the wide viewing angle effect. By having at least two sheets of light conversion films at the same time, a part of the light is reflected back while the light is scattered and emitted at the same time, and the light is excited and emitted again, to improve the light utilization rate, enhance the brightness to have a better performance of display.
