Description

背光模组结构 技术领域
本发明涉及显示技术领域，尤其涉及一种背光模组结构。
背景技术
液晶显示装置(Liquid Crystal Display，LCD)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用，如：移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕等。
现有市场上的液晶显示装置大部分为背光型液晶显示装置，其包括壳体、设于壳体内的液晶面板及设于壳体内的背光模组(Backlight module)。由于液晶面板本身不发光，需要借由背光模组提供的光源来正常显示影像。
因此，背光模组成为液晶显示装置的关键组件之一。背光模组依照光源入射位置的不同分成侧入式背光模组与直下式背光模组。直下式背光模组是将发光光源(例如阴极萤光灯管(Cold Cathode Fluorescent Lamp，CCFL)或发光二极管(Light Emitting Diode，LED))设置在液晶面板后方，直接形成面光源提供给液晶面板。而侧入式背光模组是将背光源LED灯条(Light bar)设于液晶面板侧后方的背板边缘处，LED灯条发出的光线从导光板(Light Guide Plate，LGP)一侧的入光面进入导光板，经反射和扩散后从导光板出光面射出，再经由光学膜片组，以形成面光源提供给液晶面板。对于传统的背光模组而言，当背光模组组装完成之后，便无法再改变背光模组的色度与亮度，如果在使用过程中背光模组的色度改变或亮度衰减，无法再满足用户的需求，此时只能够通过将背光模组拆开，对其中的光源模块进行更换，才能够调整背光模组的色度与亮度。因此有必要提出一种新的背光模组，在背光模块组装完成以后，不需要拆开背光模组，依然可以对背光模组的色度与亮度进行调节，方便使用，并且提高了背光模组的品质。

请同时参阅图1-4，本发明提供一种背光模组结构，包括背板6、设于 所述背板6内部且位于背板6边缘的光源模块1、设于所述背板6内部的导光板5，以及设于所述导光板5上的其他光学膜片组(未示出)。所述光源模块1与所述导光板5之间设有垂直于所述背板6底面的滤光模块组4，所述滤光模块组4包括与所述光源模块1相邻的色度滤光组2、及与所述色度滤光组2相邻的亮度滤光组3。
具体的，所述色度滤光组2由数片平行设置的不同颜色的彩色滤光片组成，所述亮度滤光组3由数片平行设置的透光能力不同的亮度滤光片组成，并且在所述背光模组结构组装完成后，可以对所述色度滤光组中的彩色滤光片的数量和种类进行选择使用，使得所述色度滤光组具有不同的色度调节能力，也可以对所述亮度滤光组中的亮度滤光片的种类和数量进行选择使用，使得所述亮度滤光组具有不同的亮度调节能力，从而实现对所述背光模组的色度与亮度进行动态调节。
优选的，所述色度滤光组2可以为一蓝色滤光片21或一黄色滤光片22，也可以为一蓝色滤光片21与一黄色滤光片22的组合。根据需要，选择使用一种或数种彩色滤光片，可以对背光模组的色度进行动态调节。
所述亮度滤光组3为第一亮度滤光片31、第二亮度滤光片32、第三亮度滤光片33和第四亮度滤光片34中任意1～4片的组合。优选的，所述第一亮度滤光片31、第二亮度滤光片32、第三亮度滤光片33和第四亮度滤光片34的滤光能力比为1:2:4:8。根据需要从上述4片亮度滤光片中选择1～4片进行组合，可以得到滤光能力介于1～15之间的亮度滤光组3，从而对背光模组的亮度进行动态调节。
以下对所述色度滤光组2和亮度滤光组3的具体调节方式进行详述：
如图2所示，所述色度滤光组2中的每一片彩色滤光片与所述亮度滤光组3中的每一片亮度滤光片的两端分别设有拨片41，优选的，所述拨片41分别位于所述每一片彩色滤光片与亮度滤光片两端的中间位置。
所述背板6的两侧板对应所述彩色滤光片与亮度滤光片两端的位置分别设有数个通孔61，所述彩色滤光片与亮度滤光片上的拨片41分别穿过所述通孔61延伸至所述背板6外部。
具体的，所述每一通孔61呈倒“L”形，包括位于竖直方向的偏移部611、及连通所述偏移部611的顶端且位于水平方向的卡合部612，且所述卡合部612位于所述偏移部611顶端的右侧。
当不需要使用某一片彩色滤光片或亮度滤光片时，可以拨动位于其两端的拨片41在通孔61的偏移部611中向上移动至所述偏移部611的顶端后，向右偏移至卡合部612中，此时，被移动的彩色滤光片或亮度滤光片 位于所述滤光模块组4的正上方和光源模块1的相对上方，与光源模块1相互错开，不参与滤光；当重新需要使用该彩色滤光片或亮度滤光片时，可以将位于卡合部612中的拨片41向左移动至偏移部611的竖直通道中，并向下拨动拨片41至最下端，此时，被移动的彩色滤光片或亮度滤光片位于光源模块1的正前方，并与所述滤光模块组4中的其它彩色滤光片或亮度滤光片位于相同的水平位置，参与滤光。
因此，通过手动上下拨动每一片彩色滤光片两端的拨片41，可以实现所述色度滤光组2在蓝色滤光片21、黄色滤光片22、或蓝色滤光片21和黄色滤光片22的组合这3种技术方案之间进行切换，从而使得所述色度滤光组2可以通过不同的彩色滤光片组合起到不同的色度调节作用；
通过手动上下拨动每一片亮度滤光片两端的拨片41，可以实现所述亮度滤光组3在所述第一亮度滤光片31、第二亮度滤光片32、第三亮度滤光片33和第四亮度滤光片34中任意1～4片所构成的技术方案的组合中进行选择，从而所述亮度滤光组3可以通过不同的亮度滤光片组合起到不同的亮度调节作用。
光源模块1发出的光经由调整后的滤光模块组4滤光后进入导光板5，并在所述导光板5上的其他光学膜片组的作用下，得到色度和亮度均匀的平面光源，从而实现对所述背光模组的色度与亮度进行动态调节，提高背光模组的品质。
优选的，所述光源模块1包括数个均匀分布的白光LED灯11。
综上所述，本发明提供的一种背光模组结构，在光源模块与导光板之间设置滤光模块组，所述滤光模块组包括由数片彩色滤光片组成的色度滤光组与由数片亮度滤光片所组成的亮度滤光组，其中所述彩色滤光片与亮度滤光片的两端分别设置拨片，通过使拨片在背板两侧的通孔中移动，使需要使用的彩色滤光片与亮度滤光片位于光源模块与导光板之间，参与滤光，使不需要使用的彩色滤光片与亮度滤光片位于光源模块的相对上方，与光源模块相互错开，不参与滤光，从而使所述色度滤光组与亮度滤光组具有不同的色度调节能力和亮度调节能力，从而实现了对所述背光模组的色度与亮度进行动态调节，提高了背光模组的品质，且结构简单，操作方便。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
