具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚,下面将结合附图及具体实施例进行详细描述。
本发明的实施例提供一种双模液晶显示装置,包括:彩膜基板10,与所述彩膜基板10对盒的阵列基板20,以及设置于所述彩膜基板10与所述阵列基板20之间的液晶层30,所述阵列基板20的像素区域包括红、绿、蓝以及白色子像素;其中,所述彩膜基板10上或者所述阵列基板20上对应于所述白色子像素的位置设置有荧光层12。
如图1和图2所示,为上述双模液晶显示装置的第一具体实施例结构示意图,如图1和图2所示,所述彩膜基板10的上偏光片11外表面对应于所述白色子像素的投影位置于设置有荧光层12。所述彩膜基板10的靠近液晶层的表面对应于所述红、绿、蓝子像素的位置,设置有相应颜色的滤光膜14、15、16。
该第一实施例中,双模液晶显示装置还包括:设置于所述阵列基板20的下方的背光源23及导光板22,所述背光源23包括:白色光源和紫外波段光源,所述白色光源和所述紫外波段光源由相互独立的开关分别控制。另外,所述阵列基板20靠近所述背光源23及导光板22的表面还设置有下偏光片21。
具体的,上述双模液晶显示装置实现明亮环境的显示和黑暗环境的显示过程如下:
如图1所示,为明亮环境显示的示意图,将背光源打开,正常模式或明亮环境模式下,关闭紫外波段光源,开启白色光源,可实现正常红绿蓝白的显示,如图1中所示,为光线通过并实现显示的示意图。
如图2所示,为黑暗环境显示的示意图,在荧光模式或暗环境模式下,关闭白色背光源,开启紫外波段光源,紫外光照射到荧光层后,可发出荧光可实现荧光显示。从而实现了双模液晶显示的目的,满足使用者需求。
如图3和图4所示,为本发明的双模液晶显示装置的第二实施例结构示意图,该第二实施例中,所述阵列基板20上对应于所述白色子像素的TFT像素区,设置有荧光层12;即将荧光层设置于LCD(液晶显示装置)内部,也同样能实现黑暗环境的荧光显示。
该实施例中,上述双模液晶显示装置还可以包括:设置于所述阵列基板20的下方的背光源23及导光板22,所述背光源23包括:白色光源和紫外波段光源,所述白色光源和所述紫外波段光源由相互独立的开关分别控制。
进一步的,所述阵列基板20靠近所述背光源23及导光板22的表面还设置有下偏光片21。
如图3所示,将荧光层制作于TFT基板,将白色子像素对应位置的TFT像素区涂覆荧光材料的滤光膜。紫外光经过下偏光片21形成偏振紫外光,偏振紫外光激发荧光材料发射出的固定偏振方向的可见光,则通过像素加载电压和盒内液晶的作用可实现荧光显示输出。
另外,需要说明的是,在上述第一实施例和第二实施例中,所述红、绿、蓝以及白色子像素平行排列或者矩阵排列。
图6示出了本发明的上述实施例的红、绿、蓝以及白色子像素矩阵排列的平面示意图;

图8为图6所示双模液晶显示装置在黑暗环境模式下显示的示意图;
图5为本发明的上述实施列的立体结构示意图,其中,红、绿、蓝以及白色子像素也以矩阵排列。
本发明的上述实施例通过在红、绿、蓝子像素对应的彩膜基板上涂覆有相应颜色的滤光膜,白色子像素位置无滤光膜。但彩膜基板上在白色子像素投影位置外侧贴敷荧光层,或者在阵列基板对应白色子像素位置有荧光材料;且上述荧光层可以曝光的方式形成在于之对应的子像素位置,背光光源除白色可见光波段的光源外,还包括紫外光波段的光源,并可以分别独立控制白色光源和紫外光源。在日光下和明亮环境中使用正常的彩色LCD显示模式,在黑暗环境中则切换成UV(紫外光)背光方式,紫外光透过的白色子像素照射到荧光层后,可使荧光层实现荧光显示。
另外,在背光源的设计中,可以在LED灯条中增加UVLED灯,添加比例以确保UV能够激发荧光层为目标设定。UVLED灯可以是独立于正常LED灯条外,独立进行配置。可以考虑配置在LED灯条上下两侧。另外,本发明的上述用于激发荧光层发光的背光源为UVLED灯,但并不限于是UVLED灯,其它可以用于激发荧光层发光的光源均适用于本发明的上述双模液晶显示装置。
另外,再如图1和图2所示,本发明的实施例还提供一种彩膜基板10,所述彩膜基板10的靠近液晶层的表面包括红、绿、蓝以及白色子像素的滤光区域14、15、16和13;所述彩膜基板上对应于所述白色子像素13的位置设置有荧光层12。
其中,所述彩膜基板的上偏光片11外表面对应于所述白色子像素13的投影位置设置有荧光层12。
其中,所述彩膜基板的靠近液晶层的表面对应于所述红、绿、蓝子像素的滤光区域位置,设置有相应颜色的滤光膜14、15、16。
