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.

Abstract: The present application relates to a quantum dot lens and a manufacturing method thereof, wherein the quantum dot comprises a lens body in the form of a rotator, a light incident surface and a light exit surface are formed on the lens body, the centers of the light incident surface and the light exit surface are located in the center axis of the lens body; and quantum dot materials are filled inside the lens body. The quantum dot lens can be used with a single LED. Since the light excited from the quantum dot materials can directly meet the need of increasing the light emitting angle, the quantum dot lens has no need to be used with a second lens for light distribution; the quality of the backlight used in the backlight illumination can be improved; and the high gamut in the direct type backlight can be achieved.
