Abstract
An edge backlight module, a display apparatus and a backlight controlling method thereof are provided. Each light guide plate (LGP) is divided into longitudinal region(s) in the same direction. The LGPs are arranged in a stacked manner. Each two adjacent LGPs are arranged as upper LGP being completely overlapped with the longitudinal region(s) of lower LGP. The longitudinal region overlapped with adjacent upper LGP is defined as a reflecting region. The longitudinal region not overlapped with adjacent upper LGP is defined as an emitting region. Each LGP has one emitting region. Each reflecting film is sandwiched between two adjacent LGPs. Light from a light emitting device is emitted from the emitting region. Combing with lighting control at lateral region(s) separately, an array region is formed. The light emitting device further includes a high saturation light emitter to render an effect with a high dynamic range and high saturation.
