附图说明
为了更清楚地说明本发明的技术方案，下面将对实施方式中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施方式，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以如这些附图获得其他的附图。
图1是本发明一种实施方式中的导光板示意图。
图2是本发明一种实施方式中的背光模组的截面示意图。
图3是图2所示的背光模组的另一方向的截面示意图。
具体实施方式
下面将结合本发明实施方式中的附图，对本发明实施方式中的技术方案进行清楚、完整地描述。
请参阅图1，本发明提供了一种导光板100，所述导光板100包括一体成型的板体20和一对挡墙40，所述板体20包括一对相对设置的第一边21和连接于所述对第一边21之间的第二边22，所述对挡墙40分别突设于所述对第一边21处，所述对挡墙40用于定位设于所述板体20上的光学膜片50(如图2和图3所示)，所述第二边22作为所述导光板100的入光边用于接触光源(未图示)。
本实施方式中，导光板100的板体20呈长方形片状结构，板体20与挡墙40之间形成收容空间，用于容置光学膜片50(如图2和图3所示)。光学膜片50可以为多种类型的层叠设置，例如扩散片、棱镜片、偏光片等。
本发明通过将所述导光板100设计成具有一体成型结构的板体20和一对挡墙40的结构，所述对挡墙40用于定位设于所述板体20上的光学膜片50，所述第二边22作为所述导光板100的入光边用于接触光源。通过在导光板100上一体成型的挡墙40结构来定位光学膜片50，使得背光模组及显示器无需边框，能够简化组装流程，降低成本。且使得使用所述导光板100的显示器具有窄边框的有益效果。
具体而言，每个所述挡墙40均包括至少两个彼此相互间隔设置的挡块42，相邻的两个所述挡块42之间形成缺口44，所述缺口44用于定位所述光学膜片50。每个挡墙40中的至少两个挡块42排列在同一条直线上。对应地，光学膜片50的边缘设有定位部，即在光学膜片边缘凸出设置的凸耳。组装时，将光学膜片50的定位部对准缺口44，然后将光学膜片50直接放置到导光板100上，使得光学膜片50的定位部落入缺口44内，实现了在水平面上的光学膜片50的定位。然后再通过安装显示面板在光学膜片50上方，使得光学膜片50夹设在显示面板和导光板100之间，以实现光学膜片50垂直方向的定位。缺口44的设置，使得在组装过程中，光学膜片50与导光板100之间能够快速定位。
