多个弹性体(13、14、15、16)设置于导光板11的四个角落处以支撑导光板11。下面以多个弹性体(13、14、15、16)中的一弹性体13为例进行说明描述。反射片12设置于导光板11的朝向弹性体13的一面。弹性体13朝向反射片12的表面至少设置有一插槽130,反射片12的边缘对应插槽130的位置至少设置有一折片120,反射片12的折片120插设于弹性体13的插槽130中而与弹性体13相对定位。其中,反射片12与其折片120之间设置有骑缝线以方便折片120的折弯。反射片12与折片120之间的角度可为近似90度或稍大一点的钝角。插槽130可设置为矩形插槽,并且插槽130垂直于导光板11朝向反射片12的一面,插槽130也可设置为其他形状的插槽,此处不作过多限制。在其他实施方式中,也可不在多个弹性体(13、14、15、16)中的一弹性体13上设置插槽130,而在其他弹性体(14、15、16)中的任意一个上设置插槽130,其他弹性体(14、15、16)插槽130的结构设置与上述一弹性体13的结构设置一致,此处不再赘述。反射片12的边缘对应插槽130位置设置折片120。

可以理解,本发明背光模组10实施方式通过多个弹性体(13、14、15、16)朝向反射片12的表面至少设置一插槽130,反射片12的边缘对应插槽130的位置至少设置一折片120,反射片12的折片120对应插设于多个弹性体(13、14、15、16)的插槽130中而与多个弹性体(13、14、15、16)相对定位,通过上述方式,能够提高背光模组中反射片定位的可靠性,提高光的利用率,适合于窄边框设计。
