Description

彩色液晶显示模组结构及其背光模组 技术领域
本发明涉及显示技术领域，尤其涉及一种彩色液晶显示模组结构及其背光模组。
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：液晶电视、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、设于壳体内的液晶显示面板及设于壳体内的背光模组(Backlight Module)。
请参阅图1，目前常见的液晶显示面板的结构是由一彩色滤光片基板(Color Filter，CF)100、一薄膜晶体管阵列基板(Thin Film Transistor Array Substrate，TFT Array Substrate)200、以及一配置于两基板间的液晶层(Liquid Crystal Layer)300所构成，其工作原理是通过在两片玻璃基板上施加驱动电压来控制液晶层的液晶分子的旋转，将背光模组提供的光线折射出来产生图像。所述液晶显示面板具有数个呈阵列式排布的像素，每一像素又包括红、绿、蓝三个子像素，且该红、绿、蓝三个子像素分别对应于所述CF基板100的红色滤光单元101、绿色滤光单元103、或蓝色滤光单元105。
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两种。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，光线经扩散板均匀化后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。
随着显示技术的进步，实现高解析度、高色域成为显示装置的重要发展方向。针对液晶显示装置，现有技术中实现高色域的主要方式还是采用由蓝色发光芯片与红色、绿色荧光粉封装的LED作为背光源，配合增加彩色滤光片厚度的方式实现。但在蓝光芯片与红色、绿色荧光粉封装的LED 中，红色荧光粉除了吸收蓝光激发出红光外，还会少量吸收绿光，而绿光激发红光的效率很低，造成该蓝光芯片与红色、绿色荧光粉封装的LED亮度降低。

为了能更进一步了解本发明的特征以及技术内容，请参阅以下有关本发明的详细说明与附图，然而附图仅提供参考与说明用，并非用来对本发明加以限制。
附图说明
下面结合附图，通过对本发明的具体实施方式详细描述，将使本发明的技术方案及其它有益效果显而易见。
附图中，
图1为目前常见的液晶面板结构的剖面示意图；
图2为本发明彩色液晶显示模组结构、及背光模组的剖面示意图；
图3为本发明彩色液晶显示模组结构、及背光模组中LED光源、导光板、及光学混光部件的俯视示意图。
具体实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请参阅图2、图3，本发明首先提供一种彩色液晶显示模组结构。该彩 色液晶显示模组结构为双场时序彩色液晶显示模组(Two Filed Sequential Color Liquid Crystal Display，Two Filed FSC-LCD)结构。
所谓“场时序彩色液晶显示模组”是一种具有高分辨率和高色彩饱和度的液晶显示模组，其通过快速的把红、绿、蓝三色图像信息分时显示在液晶显示面板上，利用人眼的视觉暂留特性合成彩色图像，可在单位显示面积上实现更高的像素密度，即把一幅图像分成若干子色场，依次显示红色、绿色、蓝色等子图像，通过人眼视觉暂留，在视网膜上利用时间混色法将三基色累加、合并，从而呈现出彩色图像，能够大幅提高光线穿透率、增加像素开口率，以提高显示图像的分辨率和色彩饱和度。
本发明的彩色液晶显示模组结构，具有两个色场，通过该两个色场混合来实现全彩显示一幅图像。如图2所示，该彩色液晶显示模组结构包括背光模组1、及设于该背光模组1上方的液晶显示面板3。
所述液晶显示面板3包括一CF基板33，一设于所述CF基板33下方的TFT基板31、及配置于所述TFT基板31与CF基板33之间的液晶层35。
所述CF基板33包括数个交替排列的黄色滤光片单元(Yellow CF，YCF)331与蓝色滤光片单元(Blue CF，B CF)333；所述液晶显示面板3具有数个呈阵列式排布的像素，每一像素包括两个子像素，且每一子像素分别对应于所述黄色或蓝色滤光片单元331、333。由于本发明的彩色液晶显示模组结构的每一像素仅包括两个子像素，一方面使像素开口率更大、光线穿透率更高，达到提高液晶显示模组分辨率和色彩饱和度的目的，另一方面可简化液晶显示面板的制造流程，提高液晶显示模组的产能。
所述背光模组1包括导光板11、设于该导光板11上表面的光学膜片组19、设于该导光板11下表面的底反射片17，及设于该导光板11一侧的所述LED光源13。
如图3所示，所述LED光源13包括数个交替排列的第一LED灯131与第二LED灯133，所述第一LED灯131采用蓝光芯片与绿色荧光粉封装(B+G荧光粉)，所述第二LED灯133采用蓝光芯片与红色荧光粉封装(B+R荧光粉)。所述数个第一LED灯131、与第二LED灯133能够避免将红、绿荧光粉混合封装于同一颗LED灯中，由于红色荧光粉吸收绿光而造成的效率下降问题，且所述第一、第二LED灯131、133均采用蓝光芯片，不存在各个LED灯驱动电压不一致、寿命衰减不一致的问题。
具体的，每个第一LED灯131和与其相邻的第二LED灯133之间的间距L小于或等于12mm。
所述数个第一LED灯131与第二LED灯133可交替点亮。
当所述第一LED灯131点亮、第二LED灯133关闭时，透过所述黄色、蓝色滤光片单元331、333的光分别为绿光、蓝光，构成第一色场。当所述第二LED灯133点亮、第一LED灯131关闭时，透过所述黄色、蓝色滤光片单元331、333的光分别为红光、蓝光，构成第二色场。所述第一、第二色场混合，快速的把蓝、绿、红三色图像信息分时显示在液晶显示面板3上，通过人眼视觉暂留，在视网膜上利用时间混色法将三基色累加、合并，实现全彩显示一幅图像。
值得一提的是，所述背光模组1还包括一光学混光部件15，该光学混光部件15设置于所述导光板11与LED光源13之间。由于所述第一、第二LED灯131、133的点亮或关闭均需要一短暂的响应时间，当所述第一LED灯131点亮、第二LED灯133关闭的瞬间，或所述第二LED灯133点亮、第一LED灯131关闭的瞬间，存在第一、第二LED灯131、133都开启的情况。所述光学混光部件15能够使得所述第一、第二LED灯131、133都开启的短暂瞬间所发出的光混合成白光。
在上述彩色液晶显示模组结构的基础上，本发明还提供一种背光模组。请同时参阅图2、图3，该背光模组1包括导光板11、设于该导光板11上表面的光学膜片组19、设于该导光板11下表面的底反射片17，及设于该导光板11一侧的所述LED光源13。
重点的，所述LED光源13包括数个交替排列的第一LED灯131与第二LED灯133，所述第一LED灯131采用蓝光芯片与绿色荧光粉封装(B+G荧光粉)，所述第二LED灯133采用蓝光芯片与红色荧光粉封装(B+R荧光粉)。所述数个第一LED灯131、与第二LED灯133能够避免将红、绿荧光粉混合封装于同一颗LED灯中，由于红色荧光粉吸收绿光而造成的效率下降问题，且所述第一、第二LED灯131、133均采用蓝光芯片，不存在各个LED灯驱动电压不一致、寿命衰减不一致的问题。
所述数个第一LED灯131与第二LED灯133可交替点亮，能够使彩色液晶显示模组实现双场时序显示。
具体的，每个第一LED灯131和与其相邻的第二LED灯133之间的间距L小于或等于12mm。
所述背光模组1还包括一光学混光部件15，该光学混光部件15设置于所述导光板11与LED光源13之间，能够使得所述第一、第二LED灯131、133都开启的短暂瞬间所发出的光混合成白光。
综上所述，本发明的一种彩色液晶显示模组结构，其每一像素包括两个子像素，每一子像素分别对应于CF基板的黄色或蓝色滤光片单元，且 LED光源包括数个交替排列的第一LED灯与第二LED灯，使得第一LED灯点亮、第二LED灯关闭时，透出绿光、蓝光，构成第一色场；第二LED灯点亮、第一LED灯关闭时，透出红光、蓝光，构成第二色场，所述第一、第二色场混合，能够实现全彩显示一幅图像，且开口率更大、光线穿透率更高，能够使得液晶显示模组具有高解析度、高色域及高效率，并可以提高液晶显示模组的产能。本发明的背光模组，其LED光源包括数个交替排列的采用蓝光芯片与绿色荧光粉封装的第一LED灯与采用蓝光芯片与红色荧光粉封装的第二LED灯，且第一、第二LED灯交替点亮，能够使彩色液晶显示模组实现双场时序显示，提高LED灯的效率，避免LED灯驱动电压不一致、寿命衰减不一致的问题。
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。
