Description

新型全彩液晶显示装置
技术领域
本实用新型涉及非主动式发光的液晶显示装置，特别是涉及一种新型全彩液晶显示装置。
背景技术
目前，平面显示器例如应用的液晶显示装置多采用TFT（薄膜场效应晶体管）-LCD技术。TFT-LCD为非主动式发光显示，通常由白光背光模组（Backlight Module）作为光源，提供均匀的系统亮度，再透过TFT-LCD液晶面板的彩色滤光膜（Color Filter）获得丰富的色彩显示。这种液晶显示装置存在以下缺点：一、现行白光背光模组应用的白光LED主要是通过蓝光LED芯片封装黄光荧光粉，点亮后发出白光，其色域只为70%左右；二、液晶面板中设有彩色滤光膜，彩色滤光膜的成本占到液晶显示装置成本的24%，且工艺制程复杂；三，彩色滤光膜的穿透率只有33%，大大降低光源的利用率。
同时，目前LED全彩显示主要针对户外大型广告屏幕应用，主要是通过大量三原色LED与每一个像素一一对应来实现全彩显示，因为每个像素都需设置一个LED灯和一个驱动，所以该方法成本昂贵，且难以在液晶电视、监控器等多像素、高画质要求的液晶显示设备上实现。
发明内容
为了克服现有技术的不足，本实用新型的目的在于提供一种以三原色LED为光源，成本低，实现全彩显示的新型全彩液晶显示装置。
本实用新型新型全彩液晶显示装置，其包括三原色LED光源、导光模块和无彩色滤光膜的液晶面板，导光模块包括导光体、光导入端和出光面，三原色LED光源设置于导光模块的光导入端，液晶面板设置于导光模块的出光面上方，出光面设有出光格，出光格与液晶面板上的子像素一一对应，三原色LED光源的光线从光导入端进入，经导光体从出光面的出光格进入液晶面板。
所述三原色LED光源嵌入或外置导光模块的光导入端，当三原色LED光源外置导光模块的光导入端时，三原色LED光源与导光模块间设有外部光缆。
所述三原色LED光源为三种不同颜色的单色LED灯，其包括红光R LED、绿光G LED和蓝光B LED。
所述导光体为光纤模组模组，光纤模组模组一端为光导入端，另一端为出光格。
所述光纤模组中包含红光、蓝光、绿光光纤，其三种颜色的光纤的排布顺序与液晶面板的子像素的排布顺序一致。每一个出光格对应一根红光、蓝光或绿光光纤构成一个子像素，即由红、绿、蓝三原色光源直接组成像素。
采用本实用新型的技术方案，通过导光模块中的光纤模组导光将三原色LED光源输出的单色光线分量传导至液晶面板的每一个对应子像素，实现以三原色光直接作为全彩显示的像素，液晶面板上无需设置彩色滤光片，降低了产品的生产成本，提高了光源利用率。以三原色LED光源作为光源，其色域可达95%左右，提高了色域。
附图说明
下面结合附图和具体实施方式对本实用新型作进一步详细的说明：
图1是本实用新型新型全彩液晶显示装置的结构示意图；
图2是本实用新型导光模块中光纤模组有序排列的结构示意图；
图3是本实用新型三原色LED光源嵌入式与导光模块连接的结构示意图。
具体实施方式
如图1-3之一所示，本实用新型包括三原色LED光源1、导光模块2和无彩色滤光膜的液晶面板3，导光模块2包括导光体21、光导入端22和出光面23，三原色LED光源1设置于导光模块2的光导入端22，液晶面板3设置于导光模块2的出光面23上方，出光面23设有出光格，出光格与液晶面板3上的子像素4一一对应，三原色LED光源1的光线从光导入端22进入，经导光体21从出光面23的出光格进入液晶面板3。
如图1或图3所示，所述三原色LED光源1嵌入或外置导光模块2的光导入端22，当三原色LED光源1外置导光模块2的光导入端22时，三原色LED光源1与导光模块2间设有外部光缆。三原色LED光源1由外部光缆导入导光模块2的光导入端22，再通过导光模块2内部光纤模组进行分光和导光，这样三原色LED光源1与导光模块2相对位置不受限制。
所述三原色LED光源1为三种不同颜色的单色LED灯，其包括红光R LED、绿光G LED和蓝光B LED。
所述导光体21为光纤模组，光纤模组一端为光导入端22，另一端为出光格23。光纤模组21通过有序缠绕实现光源从光导入端22进入，从出光格23导出。
如图2所示，所述光纤模组21包括红光、蓝光、绿光光纤，其三种颜色的光纤的排布顺序与液晶面板3的子像素4的排布顺序一致。每一个出光格对应一根红光、蓝光或绿光光纤构成一个子像素4，即由红、绿、蓝三原色光源直接组成像素。
采用本实用新型的结构，三原色LED光源1的光线从导光模块2的光导入端22进入，经导光模块2内部对应的光纤模组21分光和导光，从导光模块2出光面23的出光格导出，由于出光格与液晶面板3中的子像素4一一对应，所以液晶面板3上无需设置彩色滤光膜，这样即可在液晶面板3上实现LED全彩显示。
