具体实施方式
下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。
本发明实施例提供的一种液晶显示模组,如图1所示,该液晶显示模组包括液晶面板和背光源,所述液晶面板包括阵列基板104,所述背光源包括多个雾化透镜头101、多个光导管102和光源103,所述雾化透镜头101一侧设有一雾化面,每个雾化透镜头101与所述雾化面相对一端连接到所述光导管102一端,光导管102的另一端连接到光源103,雾化透镜头101通过对应的光导管102连接到光源103。光源103通过光导管102将光传送到各个雾化透镜头101,雾化透镜头101用于将经过光导管102的光进行雾化。
优选地,雾化透镜头101可以由外壳106包裹,光导管102穿过外壳106连接到光源103。相应的,光源103可以设置于外壳106的内部,也可以设置于外壳106外部。
图2为本发明实施例提供的雾化透镜头的示意图。雾化透镜头的正面示意图如图2a所示,雾化透镜头的正面为雾化面107,用于提供雾化光线功能;雾化透镜头的背面示意图如图2b所示,雾化透镜头的背面为光导管输出端108,即雾化透镜头背面连接光导管102的位置;雾化透镜头的侧面示意图如图2c所示,从侧面示意图中也可以看到雾化透镜头的雾化面107和光导管输出端108。
其中,优选地,光源103包括至少一个发光二极管(LED,Light EmittingDiode),且每个发光二极管连接至少一个所述雾化透镜头101。LED光源103的正面示意图如图3a所示,侧面示意图如图3b所示,LED光源103由LED110、LED灯罩111和设于LED灯罩111上的光导管输入端109组成,光导管输入端109用于将LED发出的光以点光源的形式引导出来,光导管输入端109是LED光源103上与光导管进行连接的位置。
另外,再参见图1,液晶面板的阵列基板104包括多个像素单元,雾化透镜头101阵列排布在阵列基板与像素单元相对的另一侧,即阵列基板104衬底的另一侧,且雾化透镜头101的雾化面107一侧与阵列基板接触。
较佳地,如图1所示,阵列基板104与雾化透镜头101接触的位置设有遮光部件105,即阵列基板与雾化透镜头101的雾化面107之间设有遮光部件105。
较佳的,该遮光部件105可以采用掩膜形成在阵列基板与像素单元相对的另一侧,再参见图4所示的雾化透镜头,可以清楚看见雾化透镜头表面的遮光部件105的结构,在雾化面与阵列基板接触的位置设置遮光部件105,可以防止漏光,遮光部件105也可采用与雾化透镜头一体形成。
本发明实施例提供的一种阵列基板的示意图如图5所示,所述阵列基板包括多个像素单元,每个像素单元包括R(红)、G(绿)、B(蓝)三个亚像素单元。
本发明实施例中的每个雾化透镜头可以只对应阵列基板中的一个像素单元,当然,也可以对应阵列基板中的多个像素单元,具体应用时,由于像素单元的尺寸很小,为了方便制作,雾化透镜头的尺寸可以设计的较大,只要能保证光的利用率即可。
需要说明的是,一个背光源对应的发光二极管可以只有一个,也可以有多个,可以根据显示装置的大小进行设置;一个发光二极管可以只连接一个雾化透镜头,即一个发光二极管只作为一个雾化透镜头的光源,但是发光二极管需要做的足够小,发光二极管发出的光可以通过光导管全部传输到雾化透镜头,当然一个发光二极管也可以连接多个雾化透镜头,即一个发光二极管作为多个雾化透镜头的光源。单个LED光源103连接多个雾化透镜头的示意图如图6所示。
本发明实施例中的光导管与雾化透镜头之间可以采用插入式连接方式。
其中,雾化透镜头的结构比较复杂,可以采用在阵列基板与像素单元相对的另一侧掩模刻蚀形成,但工艺很复杂,也可以采用单独制作形成,然后采用粘接或套接等其他方式将雾化透镜头与液晶面板固定在一起,只要能实现其雾化功能即可,雾化面可以采用光刻、化学刻蚀或机械打磨方式实现,当然,雾化透镜头的雾化面也可利用阵列基板的衬底,在阵列基板与像素单元相对的衬底上形成雾化面的结构,这样雾化透镜头可以不需要雾化面,只要把经过光导管的光引到阵列基板上即可。
优选的,本发明实施例所采用的光导管可以选择柔性光导管。
本发明实施例的光导管传输光线及雾化透镜头雾化光线的示意图如图7所示,通过将LED光源的光源以点光源的形式引导出来,利用一系列的光导管将光线导引到液晶显示的每一个雾化透镜头,并通过雾化透镜头的雾化光线功能,能够降低光源损失,提高光线利用效率。
本发明实施例还提供一种采用上述液晶显示模组的显示装置。
综上所述,本发明实施例通过使用光导管和雾化透镜头实现为液晶显示面板提供光源,去除了导光板、反射片、增亮膜等结构,不仅简化了液晶显示模组结构、减轻了液晶显示模组重量,满足液晶显示模组薄型化的需求,还能够有效的、动态的利用光源,满足液晶显示高对比度和动态亮度调制的需求,同时实现降低液晶显示模组功耗的目的。
以上所述,仅为本发明的较佳实施例而已,并非用于限定本发明的保护范围。
