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. By disposing the quantum film in the backlight module, the color gamut of LCD is improved.
