Description
【技术领域】
本发明涉及显示技术领域,特别是涉及一种显示面板及电子装置。
【背景技术】
为了改善观看视角,显示面板的像素结构由4个显示畴转向8个显示畴,而如何改善大视角色偏成了研究的热点。
为了改善大视角色偏,每个像素划分为主像素区和子像素区,通常需要在8显示畴像素中单独制作分享电极,分享薄膜晶体管的漏极与分享电极连接,从而通过分享电极对子像素区的电荷进行分享,以改变子像素区和主像素区的亮度,改善大视角色偏问题。但是现有的分享电极位于开口区内,因此降低了开口率。
因此,有必要提供一种显示面板及电子装置,以解决现有技术所存在的问题。
【发明内容】
本发明的目的在于提供一种显示面板及电子装置,能够提高开口率。
为解决上述技术问题,本发明提供一种显示面板,所述显示面板包括多条数据线和多条扫描线以及由所述数据线和所述扫描线限定的多个像素;所述像素包括:
主像素区,包括公共电极部和第一像素电极;所述公共电极部包括分享电极;所述分享电极的电压为固定值;
子像素区,包括第二公共电极和第二像素电极,所述子像素区还包括子驱动薄膜晶体管和分享薄膜晶体管,所述分享薄膜晶体管的漏极与所述分享电极连接,所述分享薄膜晶体管的源极与所述子驱动薄膜晶体管的漏极连接,以使所述子像素区的电压和所述主像素区的电压不同。
本发明还提供一种电子装置,其包括上述显示面板。
本发明的显示面板及电子装置,包括像素,像素包括主像素区,包括公共电极部和第一像素电极;所述公共电极部包括分享电极;所述分享电极的电压为固定值;子像素区,包括第二公共电极和第二像素电极,所述子像素区还包括子驱动薄膜晶体管和分享薄膜晶体管,所述分享薄膜晶体管的漏极与所述分享电极连接,所述分享薄膜晶体管的源极与所述子驱动薄膜晶体管的漏极连接,以使所述子像素区的电压和所述主像素区的电压不同;由于对现有的第一公共电极进行改进形成分享电极,从而使得分享电极位于非开口区,提高了开口率。
【附图说明】
图1为现有显示面板的第一种结构示意图;
图2为现有显示面板的第二种结构示意图;
图3为本发明实施例一的显示面板的结构示意图;
图4为本发明实施例二的显示面板的结构示意图。
【具体实施方式】
以下各实施例的说明是参考附加的图式,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本发明,而非用以限制本发明。在图中,结构相似的单元是以相同标号表示。
如图1所示,现有的显示面板包括数据线11和扫描线12以及由数据线11和扫描线12限定形成的像素。像素包括主像素区101和子像素区102,主像素区101包括第一公共电极13和第一像素电极14,主像素区101还包括主驱动薄膜晶体管T1,子像素区102包括第二公共电极15和第二像素电极16,子像素区102还包括子驱动薄膜晶体管T2和分享薄膜晶体管T3,主驱动薄膜晶体管T1的栅极和子驱动薄膜晶体管T2的栅极以及分享薄膜晶体管T3的栅极与扫描线12连接,所述主驱动薄膜晶体管T1的源极和所述子驱动薄膜晶体管T2的源极均与所述数据线11连接;所述子驱动薄膜晶体管T2的漏极分别与第二像素电极16以及所述分享薄膜晶体管T3的源极连接,所述分享薄膜晶体管T3的漏极与分享电极17连接。
随着解析度不断地提高,受面板尺寸的限制,像素大小得到了限制,在面板像素设计中无法引入分享电极。比如在85英寸的8K(7680*4320)的解析度下,亚像素的横向达到81um,有足够的空间在第一金属层中引入分享电极;但是如图2所示,比如在75英寸的8K显示面板中,亚像素尺寸只有71um左右,由于制程和材料的限制,没法在第一金属层中单独引入分享电极,只能将第三薄膜晶体管的漏极连接至公共电极。虽然这种设计可以改善视角,但是由于公共电极的电压出现波动,导致存储电容的电荷出现波动,从而导致显示面板出现串扰,影响了显示画质。当然在65英寸以及更小尺寸的8K面板中,将面临同样的问题。
请参照图3和4,本发明实施例一的显示面板的结构示意图。
如图3所示,本实施例的显示面板包括多条数据线11和多条扫描线12以及由所述数据线11和所述扫描线12限定的多个像素;图3以单个像素为例进行说明。
所述像素包括:主像素区101和子像素区102。
主像素区101包括公共电极部20和第一像素电极14。所述公共电极部20包括第一公共电极21和分享电极22。所述第一公共电极21与所述分享电极22之间间隔设置。
在一实施方式中,为了简化制程工艺,提高生产效率,所述分享电极22靠近所述子像素区102,所述第一公共电极21位于所述分享电极22上,此外由于分享电极靠近子像素区,还可以减小分享薄膜晶体管与分享电极之间的连接线的长度,避免电压损耗较大,进而提高了显示质量。
在一实施方式中,为了进一步提高显示质量,所述分享电极22位于所述第一像素电极14的周缘中的其中一侧,所述第一公共电极21位于所述第一像素电极14的周缘中的其余侧。比如分享电极22位于所述第一像素电极14的下侧,所述第一公共电极21位于所述第一像素电极14的左右侧和上侧。
其中所述分享电极22的电压为固定值,或者说所述分享电极22的电压是恒定的,优选地分享电极22持续接入恒定的电压。比如可以在通过外界的恒压电源单独给分享电极22供电。
所述主像素区101还可包括主驱动薄膜晶体管T1,所述主驱动薄膜晶体管T1的漏极与第一像素电极14连接。
子像素区102包括第二公共电极15和第二像素电极16,其中第二公共电极15围绕在第二像素电极16的周缘,在一实施方式中,为了避免影响开口率,所述第二公共电极15包括第三子部151,所述第三子部151覆盖所述子驱动薄膜晶体管T2的漏极以及所述分享薄膜晶体管T3的源极。第三子部151为位于第二像素电极16上方的部分。所述第二公共电极15还包括第四子部(图中未示出),第四子部位于第二像素电极16的左右侧和下侧。可以理解的,第一像素电极14和第二像素电极16的形状都可以为“米”字形,当然还可为其他形状。
所述子像素区102还包括子驱动薄膜晶体管T2和分享薄膜晶体管T3,所述分享薄膜晶体管T3的漏极与所述分享电极22连接,所述分享薄膜晶体管T3的源极与所述子驱动薄膜晶体管T2的漏极连接,以使所述子像素区102的电压和所述主像素区101的电压不同,从而使得两者的亮度不同,从而避免大视角色偏。
所述主驱动薄膜晶体管T1的栅极、所述子驱动薄膜晶体管T2的栅极以及所述分享薄膜晶体管T3的栅极均与所述扫描线12连接;
所述主驱动薄膜晶体管T1的源极和所述子驱动薄膜晶体管T2的源极均与所述数据线11连接;
所述子驱动薄膜晶体管T2的漏极分别与第二像素电极16以及所述分享薄膜晶体管T3的源极连接。
其中,所述公共电极部20与所述主驱动薄膜晶体管T1的栅极、所述子驱动薄膜晶体管T2的栅极以及所述分享薄膜晶体管T3的栅极位于同一金属层。比如,所述主驱动薄膜晶体管T1的栅极、所述子驱动薄膜晶体管T2的栅极以及所述分享薄膜晶体管T3的栅极均位于第一金属层,所述公共电极部20也位于第一金属层,从而简化制程工艺,此外还可减小显示面板的厚度。
为了提高连接的可靠性以及避免影响开口率,所述分享电极22覆盖所述主驱动薄膜晶体管T1的漏极以及所述分享薄膜晶体管T3的漏极。
由于对现有的第一公共电极进行分割,形成分享电极和主像素区的公共电极,从而使得分享电极位于非开口区,因此提高了开口率,此外可以避免公共电极与分享薄膜晶体管连接,从而避免公共电极的电压出现波动,防止存储电容的电荷出现波动,避免显示面板出现串扰,提高了显示画质。
请参照图4,图4为本发明实施例二的显示面板的结构示意图。
如图4所示,本实施例的显示面板与上一实施例的区别在于:本实施例的公共电极部仅包括所述分享电极22。
具体地,所述分享电极22包括第一子部221和第二子部222,所述第一子部221靠近所述子像素区102;所述第二子部222位于所述第一子部221的两侧。比如所述第一子部221位于第一像素电极14的下方,所述第二子部222位于第一像素电极14的左右两侧。可以理解的,本实施例的主像素区的存储电容由分享电极22与第一像素电极14形成得到。
其中,所述第一子部221可沿第一方向排布,所述第二子部222沿第二方向排布,所述第一方向与所述第二方向垂直。比如所述第一子部221沿水平方向排布,所述第二子部222沿竖直方向排布。
由于对现有的第一公共电极进行改进,形成分享电极,从而使得分享电极位于非开口区,因此提高了开口率;此外由于分享电极持续接入恒定的电压,因此电荷分享对分享电极的电压影响较小,能够避免存储电容的电荷出现波动,进而避免显示面板出现串扰,提高了显示画质。
本发明还提供一种电子装置,其包括上述任意一种显示面板,该电子装置可以为手机、平板电脑等设备。
本发明的显示面板及电子装置,包括像素,像素包括主像素区,包括公共电极部和第一像素电极;所述公共电极部包括分享电极;所述分享电极的电压为固定值;子像素区,包括第二公共电极和第二像素电极,所述子像素区还包括子驱动薄膜晶体管和分享薄膜晶体管,所述分享薄膜晶体管的漏极与所述分享电极连接,所述分享薄膜晶体管的源极与所述子驱动薄膜晶体管的漏极连接,以使所述子像素区的电压和所述主像素区的电压不同;由于对现有的第一公共电极进行改进,形成分享电极,从而使得分享电极位于非开口区,提高了开口率。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
