Abstract
The present invention provides a side-edge backlight module, which includes a backplane, a light guide plate arranged inside the backplane, a backlight source arranged inside the backplane, and a photo coupler arranged between the light guide plate and the backlight source, whereby light emitting from the backlight source is subjected to light mixing by the photo coupler and then enters the light guide plate so as to improve homogeneity of light illumination of the light guide plate at a location close to a backlight source. The side-edge backlight module arranges a photo coupler between a light incidence surface of a light guide plate and LED lights of a backlight source in order to make lights emitting from the backlight source incident to the light guide plate in a uniform manner thereby providing the light guide plate with homogeneous light illumination.
