具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
请一并参阅图1、图2及图3,图1为本发明一较佳实施方式的阵列基板的俯视图;图2为图1中一个像素区域及形成所述像素区域的第一栅极线、第二栅极线及数据线的放大结构示意图;图3为图2中沿II-II线的剖面结构示意图。所述阵列基板10包括基板110及设置在所述基板110同侧的多个第一栅极线120a、多个第二栅极线120b及多个数据线130。所述基板110包括第一表面110a,所述多个第一栅极线120a设置在所述第一表面110a上,且所述 多个第一栅极线120a向第一方向D1延伸且沿第二方向D2间隔排布。所述多个第二栅极线120b设置在所述第一表面110a上,且所述多个第二栅极线120b向所述第一方向D1延伸且沿所述第二方向D2间隔排布,且每个第二栅极线120b设置在相邻的两个第一栅极线120a之间。所述阵列基板10还包括多个公共电极线140,所述多个公共电极线140设置在所述第一表面110a上,且每个公共电极线140设置在相邻的一条第一栅极线120a及一条第二栅极线120b之间。相邻的一条第一栅极线120a及一条第二栅极线120b及相邻的两条数据线130之间限定一个像素区域。因此,在所述阵列基板10上,所述多个第一栅极线120a、所述多个第二栅极线120b及所述多个数据线130形成呈阵列分布的多个像素区域。对于一个像素区域而言,所述阵列基板10还包括设置在所述像素区域内的第一像素电极170a、第二像素电极170b、第一薄膜晶体管150及第二薄膜晶体管160。所述第一像素电极170a与所述公共电极140之间通过第一绝缘层180a绝缘,所述第二像素电极170b与所述第一像素电极之间通过第二绝缘层180b绝缘。所述第二像素电极170b的显示畴的数目大于所述第一像素电极170a的显示畴的数目。所述第一薄膜晶体管150邻近形成所述像素区域的第一栅极线120a设置,所述第一薄膜晶体管150包括第一栅区151及第一源区154。所述第一栅区151电连接形成所述像素区域的第一栅极线120a,所述第一源区154电连接所述第一像素电极170a。所述第二薄膜晶体管160邻近形成所述像素区域的第二栅极线120b设置,所述第二薄膜晶体管160包括第二栅区161及第二漏区165。所述第二栅区161电连接所述形成所述像素区域的第二栅极线120b,所述第二漏区165电连接所述第二像素电极170b。当从所述第一栅极线120a接收扫描信号切换至所述第二栅极线120b接收所述扫描信号时,所述阵列基板10从第一视角模式切换至第二视角模式,当从所述第二栅极线120b接收所述扫描信号切换至所述第一栅极线120a接收所述扫描信号时,所述阵列基板10从第二视角模式切换至第一视角模式,其中,所述第一视角模式的视角小于所述第二模式的视角。其中,所述第一方向D1可以为X轴方向,所述第二方向D2可以为Y轴方向。
具体地,当所述第一栅极线120a接收所述扫描信号时,由于所述第一薄膜晶体管150的第一栅区151电连接所述第一栅极线120a,且所述第一薄膜 晶体管150的第一漏区155连接所述第一像素电极170a,因此,所述扫描信号通过所述第一薄膜晶体管150加载在所述第一像素电极170a上,此时,所述第一像素电极170a与所述公共电极140之间形成第一电场。当把同样的扫描信号加载在所述第二栅极线120b上时,即,当所述第二栅极线120b接收所述扫描信号时,由于所述第二薄膜晶体管160的第二栅区161电连接所述第二栅极线120b,且所述第二薄膜晶体管160的第二漏区166连接所述第二像素电极170b,因此,所述扫描信号通过所述第二薄膜晶体管160加载在所述第二像素电极170b上,此时,所述第二像素电极170b与所述公共电极140之间形成第二电场。由于所述第二像素电极170b的显示畴的数目大于所述第一像素电极170a的显示畴的数目,因此,当所述第二电场比第一电场分布得更加发散,发散的第二电场能够使得所述阵列基板10应用在液晶显示装置中时,控制液晶显示装置中的液晶分子的转向的角度更广,从而使得所述第二视角模式中的视角大于所述第一视角模式的视角。通常情况下,所述第一视角模式也称为窄视角模式,所述第二视角模式也称为宽视角模式。当从所述第一栅极线120a接收扫描信号切换至所述第二栅极线120b接收所述扫描信号时,所述阵列基板10从窄视角模式切换至宽视角模式,此时,所述阵列基板10的视角变宽。当从所述第二栅极线120b接收所述扫描信号切换至所述第一栅极线120a接收所述扫描信号时,所述阵列基板10从宽视角模式切换至窄视角模式,此时,所述阵列基板10的视角变窄。
