Abstract

本实用新型涉及手机导光板,于导光板入光侧设有锯齿,该锯齿为依次相邻的等腰梯形构成,等腰梯形的锐角为70°。本实用新型采用等腰梯形的锯齿结构,能够更加有利地将入射光发散,从而提高出光均匀度。

Description

手机导光板
技术领域
本实用新型涉及导光板,尤其涉及一种光线发散均匀的手机导光板。
背景技术
侧入光式导光板是在导光板的一侧放置光源,光源从导光板的一侧进入导光板,光线经导光板发散照亮显示屏。为是导光板光线发散均匀,业内通常会在导光板的入光侧设置锯齿,以加强光线发散,但普通的锯齿光线发散效果并不理想,未能有效提高出光均匀度。
实用新型内容
本实用新型针对现有技术的上述缺陷,提供一种手机导光板,以提高出光均匀度。
为了解决上述技术问题,本实用新型是通过以下技术方案实现的:
一种手机导光板,于导光板入光侧设有锯齿,该锯齿为依次相邻的等腰梯形构成。
优选地,上述等腰梯形的锐角为70°。
一种手机导光板,于导光板入光侧设有锯齿,该锯齿为依次相邻的等腰三角形构成。
优选地,上述等腰三角形的顶角为100-120°。
从以上技术方案可以看出,本实用新型采用等腰梯形或等腰三角形的锯齿结构,能够更加有利地将入射光发散,从而提高出光均匀度。
附图说明
图1为本实用新型实施例一结构示意图。
图2为本实用新型实施例二结构示意图。
具体实施方式
下面结合具体实施方式对本实用新型作进一步详细的说明。
参见图1所示,本实用新型手机导光板,于导光板入光侧设有锯齿,该锯齿为依次相邻的等腰梯形构成,等腰梯形的锐角为70°。
再参见图2所示,本实用新型手机导光板,于导光板入光侧设有锯齿,该锯齿为依次相邻的等腰三角形构成,等腰三角形的顶角为120°。在保证出光效果的可选的范围内,上述等腰三角形顶角角度可为100-120°。
上述之具体实施例是用来详细说明本实用新型之目的、特征及功效,对于熟悉此类技艺之人士而言,根据上述说明,可能对该具体实施例作部分变更及修改,其本质未脱离出本实用新型之精神范畴者,皆应包含在本案的申请专利范围中,宜先陈明。
