Abstract

本发明公开了一种同时显示白红绿的背光源结构，包括安装在显示屏上端的导光板，所述导光板上端开设有四个通槽，所述通槽靠近导光板两端的槽口处分别安装有白色LED灯和红绿双色LED灯，所述白色LED灯和红绿双色LED灯之间安装有柔性电路板。本发明白色LED灯和红绿双色LED灯的排布方式改变为垂直排布，同时导光板和柔性电路板配套的组装方式做出调整，使白色LED灯和红绿双色LED灯水平位置保持在同一位置，这样白色LED灯和红绿双色LED灯发光之后整体效果左右差异就可消除，且垂直方向无差异。

Description

一种同时显示白红绿的背光源结构
技术领域
本发明涉及背光源技术领域，尤其涉及一种同时显示白红绿的背光源结构。
背景技术
背光源是位于液晶显示器背后的一种光源，它的发光效果将直接影响到液晶显示模块视觉效果，液晶显示器本身并不发光，它显示图形或是它对光线调制的结果。
目前的背光源要是同时拥有白色、红色、绿色的显示效果的话，常规的导光板灯槽的设计方式会导致背光出现明显的左右颜色偏差，无法满足发光一致的要求，且目前的市场上无同时能发出白色、红色、绿色的侧面发光的LED灯，只能通过单粒的白色LED灯、红绿双色LED灯来组合发光满足颜色要求，并且组合后的LED灯成一字型排列后就会导致发光时出现左右效果差异。
基于此，本发明提出一种同时显示白红绿的背光源结构。
发明内容
本发明的目的是为了解决现有技术中存在的缺点，而提出的一种同时显示白红绿的背光源结构。
为了实现上述目的，本发明采用了如下技术方案：
一种同时显示白红绿的背光源结构，包括安装在显示屏上端的导光板，所述导光板上端开设有四个通槽，所述通槽靠近导光板两端的槽口处分别安装有白色LED灯和红绿双色LED灯，所述白色LED灯和红绿双色LED灯之间安装有柔性电路板。
优选地，所述导光板的厚度大于等于白色LED灯和红绿双色LED灯的厚度之和。
优选地，所述白色LED灯和红绿双色LED灯位置处于垂直方向。
优选地，所述柔性电路板以对折的方式装配到导光板上并形成半包状态。
本发明具有以下有益效果：
本发明白色LED灯和红绿双色LED灯的排布方式改变为垂直排布，同时导光板和柔性电路板配套的组装方式做出调整，使白色LED灯和红绿双色LED灯水平位置保持在同一位置，这样白色LED灯和红绿双色LED灯发光之后整体效果左右差异就可消除，且垂直方向无差异。
附图说明

图2为本发明提出的一种同时显示白红绿的背光源结构的俯视结构示意图。
图中：1显示屏、2导光板、3通槽、4白色LED灯、5红绿双色LED灯、6柔性电路板。
具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本发明。但是本发明能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本发明内涵的情况下做类似改进，因此本发明不受下面公开的具体实施的限制。
参照图1-2，一种同时显示白红绿的背光源结构，包括安装在显示屏1上端的导光板2，导光板2上端开设有四个通槽3，通槽3靠近导光板2两端的槽口处分别安装有白色LED灯4和红绿双色LED灯5，白色LED灯4和红绿双色LED灯5之间安装有柔性电路板6。
导光板2的厚度大于等于白色LED灯4和红绿双色LED灯5的厚度之和，确保白色LED灯4和红绿双色LED灯5能够完全装配进去。
白色LED灯4和红绿双色LED灯5位置处于垂直方向。
柔性电路板6以对折的方式装配到导光板2上并形成半包状态，此时白色LED灯4和红绿双色LED灯5正好处于垂直对齐状态，这样当背光组装完毕之后点亮时发光就不会存在左右效果差异。
本发明中，在通槽3中分别放置白色LED灯4和红绿双色LED灯5，并且白色LED灯4和红绿双色LED灯5位置处于垂直方向，在柔性电路板6以对折的方式装配到导光板2上并形成半包状态后，此时白色LED灯4和红绿双色LED灯5正好处于垂直对齐状态，这样当背光组装完毕之后点亮时发光就不会存在左右效果差异。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
