Abstract

The invention discloses a backlight module. The backlight module comprises at least one light source, a light guide plate and a refractive medium. A light incidence surface of the light guide plate is adjacent to the light source, the refractive medium is adhered to the light incidence surface and an air gap is formed between the refractive medium and the light incidence surface, the refractive index of the refractive medium is smaller than the refractive index of the light guide plate, and the light beams which are emitted by the light source pass through the air gap and the refractive medium sequentially and then enter the light guide plate through the light incidence surface. The backlight module can effectively improve the light utilization rate, and can keep the air gap between the light guide plate and the light source.

Description

【Technical field】 [0001] The invention relates to a backlight module. 【Background technique】 [0002] figure 1 It is a schematic diagram of a conventional backlight module. Such as figure 1 As shown, in the backlight module 100 , the LED strip 102 is separated from the light incident surface 104 a of the light guide plate 104 by an air layer G. Such as figure 1 As shown by the dotted line path of , a light beam I emitted by the LED light bar 102 first passes through the air layer G to generate the first refraction, and then passes through the light incident surface 104a of the light guide plate 104 after the second refraction, and then passes through the light guide plate 104 The interior travels to provide a large-area luminous effect. However, when the light beam I passes through the light incident surface 104a of the light guide plate 104 from the air layer G, part of the light beam IR (such as figure 1 (shown by the solid line) will be reflected by the light incide...
