Abstract

The present disclosure relates to a backlight module as well as a display panel and an electronic device comprising the same. The backlight module includes: a light guide plate; a first low refractive plating layer; a diffusion plating layer; a high refractive plating layer; a second low refractive plating layer; a Bragg reflective plating layer; and a light source. Further, in the backlight module, refractive indexes of the first low refractive plating layer and the second low refractive plating layer are lower than that of the light guide plate, and a refractive index of the high refractive plating layer is higher than that of the light guide plate.
