  • Patent number: 9977175
    Abstract: The present disclosure provides a backlight module and a display apparatus. The backlight module comprises a light guide plate, a light source located at one side of the light guide plate at the light incident surface, a lampshade accommodating the light source and being provided with an opening structure with an adjustable size and/or position, and a control device for adjustment of the size and/or position of the opening structure on the lampshade. The amount of light which is irradiated by the backlight module to the light incident surface of the light guide plate may be varied by providing the lampshade which accommodates the light source and disposing the opening structure with an adjustable size and/or position on the lampshade, to achieve an adjustment of the brightness of a display without requiring for adjustment of the current flowing through the light source in the backlight module, thereby causing no impact on the life of the light source.

  • Patent number: 9971080
    Abstract: Disclosed is a backlight module, which includes: a light guide plate having a light incident surface; a light source disposed as facing to the light incident surface and configured for emitting a first wave-band light. The backlight module further includes: a quantum film disposed between the light source and the light guide plate. The quantum film is configured for being excited by the first wave-band light emitted from the light source and emitting a second wave-band light.
