图1是本发明实施例提供的液晶显示器的结构示意图。
图2是本发明实施例提供的液晶面板的结构示意图。
为了使本发明的目的、技术方案以及优点更加清楚明白,下面将结合附图用实施例对本发明做进一步说明。
如图1所示,本实施例提供的液晶显示器,包括液晶面板100及背光模组200,所述液晶面板100与所述背光模组200相对设置,所述背光模组200提供显示光源给所述液晶面板100,以使所述液晶面板100显示影像。

例如,若所需显示的画面中同一行的第1和第2个蓝色子像素需要输入的灰阶值为B1和B2,对应的亮度值分别为LvB1和LvB2,则按照公式:重新设定前述第1和第2个蓝色子像素的亮度值分别为LvB;然后再根据亮度曲线确定亮度值LvB对应的灰阶值B,则原来需要输入到第1和第2个蓝色子像素的灰阶值B1和B2均替换为B。按照此方式,整个液晶面板的蓝色子像素均重新计算其灰阶值,建立重新计算后的显示查找表LUT,再根据该
显示查找表LUT向像素单元提供数据信号以显示画面。
其中,在重新设定的蓝色子像素的数据参数时,红色子像素和绿色子像素的数据信号保持不变。
综上所述,相比于现有技术,本实施例提供的液晶面板中,每两个相邻列的像素单元中的蓝色子像素连接到同一条数据线,使得连接到整个液晶面板的蓝色子像素的数据线用量减少了一半。在改变面板结构的同时,通过改变驱动方式,使得同一行的像素单元中,共用一条数据线的两个蓝色子像素具有相同的亮度参数,以使液晶面板保持良好的显示效果。该液晶面板及其驱动方法减少了数据线的数量,减小了液晶面板的功耗,降低了液晶面板的设计以及制作工艺的难度,节省了制造成本。
