Description

阵列基板、显示面板及显示装置 技术领域
本发明的实施例一般地涉及显示技术领域,尤其涉及一种阵列基板、显示面板及显示装置。
背景技术
液晶显示器因具有体积小、功耗低、无辐射等特点,现已占据了平面显示领域的主导地位。由于液晶显示器的尺寸越来越大,因此对液晶显示器的显示视角范围有了更高的要求。
传统的液晶显示器中,通常由像素电极和公共电极线之间的垂直电场驱动液晶分子偏转,如果在液晶显示器的侧面观看,就会存在对比度低、色彩失真的问题,即存在可视角度狭窄的问题。为解决上述问题,现有一种液晶显示器,该液晶显示器的阵列基板包括多条数据线和多条栅线,相邻的数据线定义一列像素单元,每一个像素单元包括两个子像素电极和一个存储电容,其中一个子像素电极通过存储电容放电,使得两个子像素电极的电压不同,从而使得两个子像素电极分别对应的区域内的液晶分子的倾斜角度不同,进而提高了液晶显示器的显示视角。
但是,由于两个子像素电极的电量均会有损耗,当两个子像素电极的电量损耗不同时,两个子像素电极之间的压差可能减小,使得两个子像素电极分别对应的区域内的液晶分子的倾斜角度的差异较小,从而使得显示装置的显示角度的提高不明显,也就是说,现有的显示装置仍存在显示角度较窄的问题。
发明内容
本发明的目的在于提供一种阵列基板,用于提高显示装置的显示视角。
为了实现上述目的,本发明提供如下技术方案:
一种阵列基板,包括:相互交叉设置的多条数据线和多条栅线,相邻的所述数据线之间设置有一列像素单元,至少一个像素单元中的每个像素单元包括至少两个子像素电极、被配置成为该像素单元的至少一个子像素电极充电的电压补偿单元和被配置成使该像素单元的其余子像素电极中的至少一个的电压降低的分压单元。
本发明提供的阵列基板中,通过对像素单元的子像素电极设置可以为子像素电极充电的电压补偿单元和可以使子像素电极的电压降低的分压单元,调节电压补偿单元和分压单元以使各子像素电极的电压各不完全相同,从而使得与子像素电极分别对应的区域内的液晶分子的倾斜角度不同,从而实现显示装置的宽视角显示。
本发明的另一目的在于提供一种显示面板,用于提高显示装置的显示视角。所述显示面板包括上述技术方案提供的阵列基板。所述显示面板与上述阵列基板相对于现有技术所具有的优势相同,在此不再赘述。
本发明的另一目的在于提供一种显示视角提高的显示装置。所述显示装置包括上述技术方案提供的显示面板。所述显示装置与上述显示面板相对于现有技术所具有的优势相同,在此不再赘述。

请参阅图1,本发明实施例提供了一种阵列基板,包括:相互交叉设置的多条数据线20和多条栅线10,相邻数据线20之间设置有一列像素单元,至少一个像素单元中的每个像素单元包括相互独立的至少两个子像素电极,以及控制对应的子像素电极充放电的第一薄膜晶体管;例如:第一薄膜晶体管41,第 一薄膜晶体管41包括:栅极411,漏极412,和源极413;所述至少一个像素单元中的每个像素单元还包括:被配置成为该像素单元的至少一个子像素电极充电的电压补偿单元51和被配置成使该像素单元的其余子像素电极中的至少一个的电压降低的分压单元52。
本发明实施例提供的阵列基板中,通过为像素单元设置可以为子像素电极充电的电压补偿单元51和可以使子像素电极的电压降低的分压单元52,调节电压补偿单元51和分压单元52以使各子像素电极的电压各不完全相同,从而使得与子像素电极分别对应的区域内的液晶分子的倾斜角度不同,从而实现显示装置的宽视角显示。
上述像素单元中的子像素电极的数量可以为两个或多个,下面以像素单元包括两个子像素电极为例,对本发明的一种示例性实施方式进行描述。请参阅图1、图2和图3,至少一部分像素单元中的每一个包括两个子像素电极,分别为第一子像素电极31和第二子像素电极32;像素单元还可以包括公共电极线61,公共电极线61设置于阵列基板的栅极绝缘层81和衬底基板82之间,电压补偿单元51分别与第一子像素电极31和第二子像素电极32电性连接,分压单元52分别与第一子像素单元31和公共电极线61电性连接。上述阵列基板工作时,在栅线10中通过扫描信号时,各第一薄膜晶体管41处于开态或导通状态,此时数据线20通过各第一薄膜晶体管41为对应的第一子像素电极31和第二子像素电极32充电,同时,第一子像素电极31的电量有部分流入分压单元52和电压补偿单元51。由于第一子像素电极31和第二子像素电极32的充电时间相同,因此充电完成后,第一子像素电极31的电压低于第二子像素电极32的电压,从而使得第一子像素电极31对应的区域内的液晶分子的倾斜角度,与第二子像素电极32对应的区域内的液晶分子的倾斜角度不同,进而提高了显示装置的显示视角;同时,即使第二子像素电极32的电量有所损耗,电压补偿单元51可为第二子像素电极32补充电量,使得第二子像素电极32的电压始终高于第一子像素电极31的电压,从而进一步提高了显示装置的 显示视角。
将会理解,根据不同显示视角的需求,可以为显示装置的一部分或全部像素单元提供上述电压补偿单元和分压单元,而具有电压补偿单元和分压单元的像素单元的子像素电极中的一部分或全部的电压可以彼此不同。
需要说明的是,附图1中,分压单元52和电压补偿单元51可以通过公用连接结构(例如图3中的第二薄膜晶体管42)分别与第一子像素电极31电性连接,因选取的视角限制,因此附图中未示出分压单元52和电压补偿单元51具体是如何通过公用连接结构分别与第一子像素电极31电性连接。当然,分压单元52和电压补偿单元51也可以通过相互独立的连接结构分别与第一子像素电极31电性连接。这同样适用于其它实施例。
为了控制第一子像素电极31流出的电量,分压单元52包括分压电容92和分压薄膜晶体管;电压补偿单元51包括电压补偿电容91和电压补偿薄膜晶体管。可通过调整分压薄膜晶体管的电学性能控制第一子像素电极31流入分压电容92的电量,和/或通过调整电压补偿薄膜晶体管的电学性能控制第一子像素电极31流入电压补偿电容91的电量,分压薄膜晶体管和/或电压补偿薄膜晶体管的电学性能包括迁移率,沟道宽长比等。在一个示例中:分压薄膜晶体管的沟道的宽长比小于第一薄膜晶体管41的沟道的宽长比;且电压补偿薄膜晶体管的沟道的宽长比小于第一薄膜晶体管41的沟道的宽长比。
上述分压单元52和电压补偿单元51可公用同一个薄膜晶体管,也就是说,上述分压薄膜晶体管与电压补偿薄膜晶体管可为同一个薄膜晶体管;当分压薄膜晶体管与电压补偿薄膜晶体管为同一个薄膜晶体管时,在图3中,该薄膜晶体管为第二薄膜晶体管42,第二薄膜晶体管42即为分压单元52和电压补偿单元51分别与第一子像素电极31电性连接的公用连接结构。第二薄膜晶体管42的源极423与第一子像素电极31电性连接,第二薄膜晶体管42的栅极421与栅线10电性连接,第二薄膜晶体管42的漏极422设置在阵列基板的钝化层83和栅极绝缘层81之间;分压电容92的一极与第二薄膜晶体管42的漏极422 电性连接,分压电容92的另一极与公共电极线61电性连接;电压补偿电容91的一极与第二薄膜晶体管42的漏极422电性连接,电压补偿电容91的另一极与第二子像素电极32电性连接。
上述阵列基板工作时,在栅线10中通过扫描信号时,各第一薄膜晶体管41处于开态或导通状态,此时数据线20通过各第一薄膜晶体管41为对应的第一子像素电极31和第二子像素电极32充电,同时,第一子像素电极31的电量有部分通过第二薄膜晶体管42分别流入分压电容92和电压补偿电容91,由于第一子像素电极31和第二子像素电极32的充电时间相同,因此充电完成后,第一子像素电极31的电压低于第二子像素电极32的电压,从而使得第一子像素电极31对应的区域内的液晶分子的倾斜角度,与第二子像素电极32对应的区域内的液晶分子的倾斜角度不同,进而提高了显示装置的显示视角;同时,当第二子像素电极32的电量有所损耗之后,电压补偿电容91为第二子像素电极32补充电量,使得第二子像素电极32与第一子像素电极31之间的压差增大,且第二子像素电极32的电压始终高于第一子像素电容31的电压,从而进一步提高了显示装置的显示视角。
上述第一薄膜晶体管41的栅极411和第二薄膜晶体管42的栅极421分别与同一条栅线电性连接,因此,第一薄膜晶体管41和第二薄膜晶体管42的处于开态的时间相同。
为更精确控制第二薄膜晶体管42处于开态或导通状态的时间,如图4所示,在另一种实施方式中,像素单元还可以包括辅助栅线11,第二薄膜晶体管42的栅极421与辅助栅线11电性连接,第二薄膜晶体管42的源极423与第一子像素电极31电性连接。例如:辅助栅线可位于第一子像素电极31和第二子像素电极32之间,第二薄膜晶体管42的漏极422设置在钝化层83和栅极绝缘层81之间;分压电容92的一极与第二薄膜晶体管42的漏极422电性连接,分压电容92的另一极与公共电极线61电性连接;电压补偿电容91的一极与第二薄膜晶体管42的漏极422电性连接,电压补偿电容91的另一极与第二子 像素电极32电性连接。
如此设计,栅线10控制各第一薄膜晶体管41的开关状态,以为对应的第二子像素电极32和第一子像素电极31充电,辅助栅线11控制第二薄膜晶体管42的开关状态,以使第一子像素电极31的电压降低,从而使得第一薄膜晶体管41和第二薄膜晶体管42处于开态的时间可以不同,也就是说,可以通过辅助栅线11控制第二薄膜晶体管42处于开态的时间,从而控制第一子像素电极31和第二子像素电极32之间的压差。举例来说,当第一薄膜晶体管41的沟道的宽长比与第二薄膜晶体管42的宽长比相同时,为保证第一子像素电极31的电量不会全部流出,第二薄膜晶体管42处于开态的时间需要小于第一薄膜晶体管41处于开态的时间;在合理的时间内,第二薄膜晶体管42处于开态的时间越长,第一子像素电极31的电压越低,从而使得第一子像素电极31与第二子像素电极32的压差越大,进而进一步提高了显示装置的显示视角。
值得一提的是,辅助栅线11还可以设置在如图4中第一子像素电极31的上方,或设置在如图4中第二子像素电极32的下方。
在上述各像素单元中,分压电容92的一极与公共电极线61可以直接电性连接,或者,请参阅图5,分压电容92的一极与还可以通过辅助电极62与公共电极线61电性连接,此时,每个像素单元还包括辅助电极62,辅助电极62通过辅助过孔73与公共电极线61电性连接,分压电容92的一极与辅助电极62电性连接。例如:辅助电极62位于公共电极线61与第二薄膜晶体管42的漏极422之间,辅助电极62通过辅助过孔73与公共电极线61电性连接,分压电容92的一极与辅助电极62电性连接。由于辅助电极62的设置位置决定了辅助电极62与第二薄膜晶体管42的漏极之间在阵列基板的厚度方向上的距离,因此当辅助电极62与第二薄膜晶体管42的漏极之间在该厚度方向上的距离小于公共电极线61与第二薄膜晶体管42的漏极之间在该厚度方向上的距离时,分压电容92的两极之间在该厚度方向上的距离变小,分压电容92的电容量增加,第一子像素电极31与第二子像素电极32之间的压差变大,从而进一 步提高了显示装置的显示视角。
上述各像素单元中,辅助电极62可以与第二子像素电极32为不同种材料制成,在制备阵列基板时,辅助电极62和第二子像素电极32需要分别制备;优选地,辅助电极62与第二子像素电极32为同种材料制成,且辅助电极62与第二子像素电极32同层设置,如此设计,使得在制备阵列基板的过程中,辅助电极62和第二子像素电极32可在同一组制备过程中同时形成,从而简化了制备阵列基板的过程,减少了制备阵列基板的时间,从而提高了制备阵列基板的效率。
为了进一步提高制备阵列基板的效率,在一种优选实施方式中,分压电容92的一极与第二薄膜晶体管42的漏极为一体结构,分压电容92的另一极与公共电极线61为一体结构;电压补偿电容91的一极与第二薄膜晶体管42的漏极为一体结构,电压补偿电容91的另一极与第二子像素电极32为一体结构。如此设计,使得在制备阵列基板的过程中,分压电容92的一极与第二薄膜晶体管42的漏极可在同一组制备过程中同时形成,分压电容92的另一极与公共电极线61可在同一组制备过程中同时形成,电压补偿电容91的一极与第二薄膜晶体管42的漏极可在同一组制备过程中同时形成,电压补偿电容91的另一极与第二子像素电极42可在同一组制备过程中同时形成,从而简化了制备过程,减少了制备阵列基板的时间,从而进一步提高了制备阵列基板的效率。
为了提高上述各像素单元的开口率,请参阅图6,优选地,在像素单元中,分压电容92与公共电极线61相连的一极,和电压补偿电容91与第二子像素电极32相连的一极在阵列基板的厚度方向上相对设置,即在阵列基板的表面上的正投影彼此至少部分地重叠(如图6中的虚线圈所示)。如此设计,当分压电容92的两极的面积和电压补偿电容91的两极的面积均不变的情况下,使得显示装置中,用于遮挡分压电容92和电压补偿电容91的遮挡物的面积减小,从而提高了各像素单元的开口率。
以上均是以像素单元中的子像素电极的数量为两个为例进行说明,当像素 单元中子像素电极的数量为两个以上时,可采用如下设置方式:像素单元包括至少一个被配置成为子像素电极充电的电压补偿单元51和至少一个被配置成使子像素电极的电压降低的分压单元52。举例来说,请参阅图7,当像素单元中子像素电极的数量为四个,分别为第一子像素电31、第二子像素电极32、第三子像素电极33和第四子像素电极34时,该像素单元还包括四个第一薄膜晶体管41、三个第二薄膜晶体管42、三个电压补偿电容91,三个分压电容92、以及公共电极线61。各第一薄膜晶体管41的沟道的宽长比相同,各第二薄膜晶体管42的沟道的宽长比各不相同,且各第二薄膜晶体管42的沟道的宽长比均小于各第一薄膜晶体管41的沟道的宽长比。
上述各像素单元中,各第一薄膜晶体管41的栅极411均与栅线10电性连接,各第一薄膜晶体管41的源极413均与数据线20电性连接,各第一薄膜晶体管41的漏极412各自对应与一个子像素电极电性连接;三个第二薄膜晶体管42中,其中一个第二薄膜晶体管42的源极423与第一子像素电极31电性连接,该第二薄膜晶体管42的栅极421与栅线10电性连接,该第二薄膜晶体管42的漏极422设置在阵列基板的钝化层83和栅极绝缘层81之间;其中一个电压补偿电容91的一极与该第二薄膜晶体管42的漏极422电性连接,另一极与第二子像素电极32电性连接;其中一个分压电容92的一极与该第二薄膜晶体管42的漏极422电性连接,另一极与公共电极线61电性连接;余下的两个第二薄膜晶体管42的源极423各自对应与余下的两个子像素电极电性连接,上述余下的两个第二薄膜晶体管42的栅极421分别与栅线10电性连接,上述余下的两个第二薄膜晶体管42的漏极422均设置在阵列基板的钝化层83和栅极绝缘层81之间;余下的两个电压补偿电容91的一极分别对应与上述余下的两个第二薄膜晶体管42的漏极422电性连接,上述余下的两个电压补偿电容91中一个电压补偿电容91的另一极与第二子像素电极32电性连接,另一个电压补偿电容91的另一极与第四子像素电极34电性连接。余下的两个分压电容92的一极分别对应与上述余下的两个第二薄膜晶体管42的漏极422电性连接, 上述余下的两个分压电容92的另一极分别与公共电极线61电性连接。
上述阵列基板工作时,栅线10通过各第一薄膜晶体管41为对应的四个子像素电极充电,同时,第一子像素电极31、第三子像素电极33和第四子像素电极34的部分电量分别流入各自对应的分压电容92,且由于三个第二薄膜晶体管42的沟道的宽长比各不相同,因此,从第一子像素电极31、第三子像素电极33和第四子像素电极34中流出的电量不同,从而使得第一子像素电极31、第三子像素电极33和第四子像素电极34的电压均小于第二子像素电极32的电压,且第一子像素电极31、第三子像素电极33和第四子像素电极34的电压各不相同,从而使得第一子像素电极31、第二子像素电极32、第三子像素电极33和第四子像素电极34各自对应的区域内的液晶分子的倾斜角度各不相同,进而提高了显示装置的显示视角;同时,当第二子像素电极32、第三子像素电极33和第四子像素电极34的电量有所损耗之后,三个电压补偿电容91分别为第二子像素电极32、第三子像素电极33和第四子像素电极34补充电量,使得第二子像素电极32、第三子像素电极33和第四子像素电极34的电压始终高于第一子像素电极的电压,且可控制各电压补偿电容92,使各电压补偿电容92为第二子像素电极32、第三子像素电极33和第四子像素电极34补充电量相等,以使第二子像素电极32、第三子像素电极33和第四子像素电极34的电压始终不同,从而进一步提高了显示装置的显示视角。
