Side-entry backlight module

The embodiments of the invention propose a side-entry backlight module and a terminal device. The side-entry backlight module comprises a light guiding plate and a plurality of light emitting diode LED lights. The LED lights are arranged on the side face of the light emitting plate. The light entry face of the light guiding plate comprises a plurality of sub-light entry faces. Each sub-light entry face is a non-planar face, and each sub-light entry face is provided with a first axle wire; and each sub-light entry face is symmetrical according to its own first axle wire. Each sub-light entry face is provided with at least two LED lights; and the LED lights on the sub-light entry face are symmetrically arranged according to the axle wire of the sub-light entry face. The invention is used to increase the brightness scope of the side-entry backlight module. 本发明实施例提供种侧入式背光模组和终端设备，侧入式背光模组中包括导光板和多个发光二极管LED灯，LED灯设置在导光板的侧面，其中，所述导光板的入光面包括多个子入光面，每个子入光面为非平面，每个子入光面具有第中轴线，每个子入光面相对于其自身的第中轴线对称；每个子入光面上设置有至少两个LED灯，所述子入光面上的LED灯
