Backlight module and liquid crystal display

A backlight module, comprising:

• a light guide plate, which comprises a light incident surface, a light emission surface, and a first reflection surface, the light incident surface and the first reflection surface being respectively connected to two adjacent side edges of the light emission surface, the light incident surface comprising a first light incident section and a second light incident section, the first light incident section being located between the second light incident section and the first reflection surface, the first light incident section and the first reflection surface defining therebetween a first acute angle;
• a light bar, which comprises a first light source and a second light source, the first light source being arranged to exactly correspond to the first light incident section so that light from the first light source is allowed to enter the light guide plate to be reflected by the first reflection surface for subsequent outward emission from the light emission surface, the second light source being arranged to exactly correspond to the second light incident section so that light from the second light source is allowed to enter the light guide plate for subsequent outward emission from the light emission surface;
• and
• a control circuit, which is electrically connected to the first light source and the second light source to control ON/OFF states of the first light source and the second light source.
