Abstract

The invention discloses a backlight source module, a liquid-crystal display device and a mobile terminal. The backlight source module comprises a light source, a light guide plate, a light reflecting plate and a shading band, wherein the light guide plate comprises a side incidence plane, an emergence plane adjacently connected with the side incidence plane and a bottom face adjacently connected with the side incidence plane and opposite to the emergence plane. The light source is arranged on the side incidence plane of the light guide plate. The light reflecting plate is arranged under the bottom face, the shading band is arranged above the light guide plate, a gap exists in the light guide plate, and the shading band is a curved surface and is used for reflecting light refracted out of the gap onto the light guide plate again so as to emit the refracted light of the light out of an AA area side face after multiple times of reflection. The light can be prevented from emerging from the side face of the gap, the phenomenon of light leakage of an AA area is not produced, and the usage experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a backlight source module, a liquid crystal display device and a mobile terminal. Background technique [0002] With the continuous improvement of LED light efficiency, the market share of LED backlight is also increasing day by day. At present, the backlight module mainly adopts two methods of direct-type or side-type. figure 1 It is a schematic diagram of the structure of the side-entry backlight module in the prior art. figure 1 It can be seen that the side-entry backlight module includes: a light source, a light guide plate, a reflector and a shading belt, wherein the light source is set on the side of the light guide plate to provide light, and the light guide plate is set on the back cover to emit light. The light from the area is converted to an area light. The light-shielding strip is arranged above the light guide plate. [0003] In the side-type backlight module, a...
