Abstract: The present disclosure provides a tunable backlight device, a display device and method of driving the display device. The tunable backlight device comprises: at least one backlight apparatus with high color gamut and low luminance; at least one backlight apparatus with low color gamut and high luminance; a storage configured to store a library of current feedback coefficients; a current feedback apparatus, configured to determine a first current feedback coefficient (K1) for the backlight apparatus with high color gamut and low luminance and a second current feedback coefficient (K2) for the backlight apparatus with low color gamut and high luminance, according to the requirements, respectively; a backlight driving apparatus configured to supply respective currents to both the backlight apparatuses to emit lights, based on the first and the second current feedback coefficients, respectively; and a light guide plate configured to mix the lights emitted from the both backlight apparatuses.

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.

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.
