Abstract

本实用新型涉及电子零配件领域,尤其是一种笔记本导光板。其包括出光面、入光面和底面,出光面位于底面上部,与底面平行,入光面与出光面及底面垂直相交,出光面上设有凸块。凸块为金字塔状。底面上分布有半球体。在导光板的出光面上设置凸块,可使出射光线变窄、提高出光辉度,在底面上设置半球体,可提高漫反射效果,不需要另外设置扩散片和棱镜片便可达到聚光的功效,从而大大减小导光板的整体体积,降低生产成本。

Description

笔记本导光板
技术领域
本实用新型涉及电子零配件领域,尤其是一种笔记本导光板。
背景技术
导光板主要应用在电子产品的液晶显示器中,如笔记本电脑、液晶电视、数码相机等,现有的导光板由网点、板体、扩散片和棱镜片组成,此结构不但增大了导光板的体积,而且大大增加了生产成本。
发明内容
为了克服现有的导光板体积大,生产成本高的不足,本实用新型提供了一种笔记本导光板。
本实用新型解决其技术问题所采用的技术方案是:一种笔记本导光板,包括出光面、入光面和底面,出光面位于底面上部,与底面平行,入光面与出光面及底面垂直相交,出光面上设有凸块。
凸块为金字塔状。
底面上分布有半球体。
本实用新型的有益效果是,在导光板的出光面上设置凸块,可使出射光线变窄、提高出光辉度,在底面上设置半球体,可提高漫反射效果,不需要另外设置扩散片和棱镜片便可达到聚光的功效,从而大大减小导光板的整体体积,降低生产成本。
附图说明
下面结合附图和实施例对本实用新型进一步说明。
图1是本实用新型的示意图;
图2是本实用新型的俯视图。
图中1. 出光面,2. 入光面,3. 底面,4. 凸块,5. 半球体。
具体实施方式
如图1是本实用新型的示意图,一种笔记本导光板,包括出光面1、入光面2和底面3,出光面1位于底面3上部,与底面3平行,入光面2与出光面1及底面3垂直相交,出光面1上设有凸块4。凸块4为金字塔状。底面3上分布有半球体5。
出光面1上设有凸块4,凸块4为金字塔状,是由相互垂直的横向三棱条与纵向三棱条交叉而成,可使出射光线变窄、提高出光辉度,底面3上分布有半球体5,可破坏光束在导光板内部传输的全反射条件,且使其散射,以提高导光板出射光束的均匀性。

Claims (3)
