Abstract

The embodiment of the invention provides a backlight module and a display device. According to the backlight module provided by the embodiment of the invention, the plurality of first microstructures are arranged on the surface of the primary lens of the light-emitting device, and / or the primary lens is arranged to comprise the plurality of second light-transmitting film layers with different refractive indexes, so that light diffusion can be realized by utilizing the first microstructures and / or the plurality of second light-transmitting film layers with different refractive indexes, light emitted by the light-emitting device is more uniform, and when the light emitted by the light-emitting device is more uniform, the backlight module can realize light emitting uniformity under a smaller light mixing distance, and thus the thickness of the backlight module can be reduced, and the light and thin design of the display device is realized.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and a display device. Background technique [0002] With the continuous development of display technology, display devices are gradually developing in the direction of thinner and lighter. Existing display devices generally include a housing, a display panel fixedly accommodated in the housing, a middle frame, a backlight module, etc., and the thickness of the backlight module is one of the key factors determining the thickness of the display device. [0003] In order to obtain a more uniform light output effect, the existing backlight module is usually provided with a longer light mixing distance, which will result in a larger thickness of the backlight module, which is not conducive to the thinner and lighter design of the display device. Contents of the invention [0004] Embodiments of the present application provide a backlight module and a d...
