Description
本申请涉及显示技术领域,尤其涉及一种多畴像素结构的显示面板。
3T像素中,8Domain的3T架构中,像素被一分为主像素区和次像素区,由于主像素区和次像素区在同一时间段(同灰阶/某一画面时),与上玻璃板(CF基板)的压差不一致,一般主像素区的压差较大,而次像素区的压差较小。实际点亮发现,尤其在中低灰阶时,像素主要由主像素区贡献亮度。因此在3T像素中,由于分压比的存在,使得在中低灰阶时,主要由主像素区贡献亮度,次像素区处于很暗状态,甚至达不到液晶偏转的阈值电压。因此造成显示面板在中低灰阶时,精细画面的细腻度不足从而影响显示效果的技术问题。

为了更清楚地说明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单介绍,显而易见地,下面描述中的附图仅仅是申请的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

图2为本申请实施例一提供的一种显示面板的结构示意图;
图3为本申请实施例一提供的另一种显示面板的结构示意图;
图4为本申请实施例二提供的一种显示面板的结构示意图;

以下各实施例的说明是参考附加的图示,用以例示本申请可用以实施的特定实施例。本申请所提到的方向用语,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申请,而非用以限制本申请。在图中,结构相似的单元是用以相同标号表示。
本申请针对现有的多畴像素结构的显示面板,由于在中低灰阶显示时,画面的细腻度不足从而影响显示效果的技术问题,本实施例能够解决该缺陷。
本申请提供一种具有多畴像素结构的显示面板,其像素结构可以为二畴、四畴、八畴中的一种。本实施例仅以3T_8domain(八畴3晶体管)像素结构为例进行说明。
如图1所示,为本申请实施例提供的八畴像素结构示意图。在显示面板内阵列的设置有多个子像素,每个所述子像素均包括主像素区10和次像素区20。对应每一行子像素分别设置一条扫描线30,所述扫描线30位于所述主像素区10和所述次像素区20之间,对应每一列子像素分别设置一条数据线40。
所述子像素内还包括主区薄膜晶体管T1以及主区存储电容,次区薄膜晶体管T2以及次区存储电容,以及共享薄膜晶体管T3等。所述主区薄膜晶体管T1的栅极连接所述扫描线30,其源极/漏极连接所述数据线40,其漏极/源极连接对应所述主像素区10的主区像素电极11。所述次区薄膜晶体管T2的栅极连接所述扫描线30,其源极/漏极连接所述数据线40,其漏极/源极连接对应所述次像素区20的次区像素电极21。所述共享薄膜晶体管T3的栅极连接所述扫描线30,其源极和漏极分别连接所述次区薄膜晶体管T2的漏极/源极和共享电极。其中,所述主区像素电极11和所述次区像素电极21的形状均呈“米”字形。
其中,在本申请提供的所述显示面板上,有一部分所述子像素的所述主像素区10和所述次像素区20在位置上与另一部分所述子像素的所述主像素区10和所述次像素区20呈预设角度翻转设置,以增加所述主像素区10和所述次像素区20排列位置的无序度。其中,所述预设角度为10°~180°。也就是说,在本申请提供的所述显示面板上,同一行/列所述子像素的所述主像素区10或所述次像素区20的相对位置关系不相同,从而改善中低灰阶显示时画面的细腻度不足的问题。
如图2所示,为本申请实施例一提供的一种显示面板的结构示意图。所述显示面板1包括阵列分布的像素单元A,每一所述像素单元A至少包括三个子像素,如红色子像素R、绿色子像素G以及蓝色子像素B。每一所述子像素均包括所述主像素区10和所述次像素区20,所述主像素区10与所述次像素区20按预设面积比例设置,如所述主像素区10的面积占整个所述子像素开口率的25%~50%。其中,所述子像素的像素结构如图1中所示,此处不再赘述。
在本实施例中,同一所述像素单元A中的不同所述子像素的所述主像素区10和所述次像素区20的相对位置关系相同。相邻两所述像素单元A中的所述子像素的所述主像素区10和所述次像素区20在位置关系上呈180°翻转设置,从而增加发光位置(所述主像素区10)的无序度。
如图中所示,相邻的两个像素单元A中,其中的一个像素单元A的所述红色子像素R、所述绿色子像素G、所述蓝色子像素B的所述主像素区10均位于所述次像素区20的上方,另一个像素单元A的所述红色子像素R、所述绿色子像素G、所述蓝色子像素B的所述主像素区10均位于所述次像素区20的下方。
其中,相邻两所述像素单元A为在所述扫描线30和/或所述数据线40的延伸方向上的相邻关系。
在一种实施例中,所述主像素区10的面积占整个所述子像素开口率的40%~50%。此设计可以大大降低所述主像素区10或所述次像素区20位置翻转带来的栅极线和电极线等走线绕线的长度和复杂度。
在其他实施例中,所述像素单元A除了有上述RGB三种像素结构外,还可以包括白色子像素W,即像素单元包括RGBW四个子像素;或者是RGBG等像素结构。此外,此处不做限定。
如图3所示,为本申请实施例一提供的另一种显示面板的结构示意图。图3与图2的区别在于:所述显示面板1中至少有两个所述像素单元A形成一像素组B,相邻两个所述像素组B中的所述子像素的所述主像素区10和所述次像素区20在位置关系上呈180°翻转设置。
换句话说就是,所述显示面板1包括多个所述像素组B,每一所述像素组B包括至少两所述像素单元A,每一所述像素组B内所有的所述子像素的所述主像素区10与所述次像素区20的相对位置关系相同。相邻的两个像素组B中,其中一个像素组B所有的所述子像素的所述主像素区10均位于所述次像素区20的上方,另一个像素组B所有的所述子像素的所述主像素区10均位于所述次像素区20的下方。
其中,相邻两所述像素组B为在所述扫描线30和/或所述数据线40的延伸方向上的相邻关系。
现有显示面板一般所有子像素的主像素区均位于次像素区的一侧,使得同一行子像素中的主像素区和次像素区呈直线条状间隔分布,固定统一的主像素区发光可能使得部分画面颗粒感增加,从而引起在中低灰阶显示时精细画面的细腻度不足等问题。而本实施例通过将部分所述像素单元A的所述主像素区10和所述次像素区20的位置按照一定顺序翻转,有利于在中低灰阶图像显示下所述次像素区20发光微弱甚至无法亮起时,通过增加发光位置(所述主像素区10)的无序度,达到提高发光面均匀度等目的,从而提高画面的细腻度。
如图4所示,为本申请实施例二提供的一种显示面板的结构示意图。所述显示面板1包括阵列分布的像素单元A,每一所述像素单元A包括红色子像素R、绿色子像素G以及蓝色子像素B。每一所述子像素均包括所述主像素区10和所述次像素区20,在同一所述像素单元A中,相邻两所述子像素的所述主像素区10和所述次像素区20在位置关系上呈180°翻转设置。
如图中所示,其中一所述像素单元A的红色子像素R的所述主像素区10位于所述次像素区20的上方,绿色子像素G的所述主像素区10位于所述次像素区20的下方,蓝色子像素B的所述主像素区10位于所述次像素区20的上方,或者是与此设计相反的方式。在所述显示面板1上所述像素单元A以此种像素结构阵列的分布。其中,所述子像素的像素结构如图1中所示,此处不再赘述。
其中,相邻两所述子像素为在所述扫描线30和/或所述数据线40的延伸方向上的相邻关系。
如图5所示,为本申请实施例二提供的另一种显示面板的结构示意图。图5与图4的区别在于:所述显示面板1包括多个子像素组C,每一所述子像素组C包括至少两个子像素,每一所述子像素组C内所有的所述子像素的所述主像素区10与所述次像素区20的相对位置关系相同。相邻的两个子像素组C中,其中一个子像素组C所有的所述子像素的所述主像素区10均位于所述次像素区20的上方,另一个子像素组C所有的所述子像素的所述主像素区10均位于所述次像素区20的下方。即相邻两个所述子像素组C中的所述主像素区10和所述次像素区20在位置关系上呈180°翻转设置,从而增加所述主像素区10的无序度。
其中,相邻两所述子像素组C为在所述扫描线30和/或所述数据线40的延伸方向上的相邻关系。
如图6所示,为本申请实施例二提供的又一种显示面板的结构示意图。图6与图4相比,其区别在于:所述显示面板1包括阵列分布的所述子像素,相邻两所述子像素的所述主像素区10和所述次像素区20在位置关系上呈180°翻转设置。
也就是说,除了同一所述像素单元A内相邻两所述子像素的所述主像素区10和所述次像素区20在位置关系上不同之外,相邻两个所述像素单元A内同种子像素的所述主像素区10和所述次像素区20在位置关系上也不同。
如图中所示,相邻的两个像素单元A中,其中的一个像素单元A的所述红色子像素R的所述主像素区10位于所述次像素区20的上方,则另一个像素单元A中所述红色子像素R的所述主像素区10位于所述次像素区20的下方。相邻两所述像素单元A中所述绿色子像素G、所述蓝色子像素B的设计与所述红色子像素R的设计类似,此处不再赘述。
通过此设计,使得不管在所述扫描线30的延伸方向上,还是在所述数据线40的延伸方向上,相邻两所述子像素的所述主像素区10和所述次像素区20在位置关系上呈180°翻转设置。从而最大程度上增加所述主像素区10的无序度,在中低灰阶显示下所述次像素区20发光微弱甚至无法亮起时,可以最大程度上达到提高发光面均匀度的目的,进而提高画面的细腻度。
综上所述,本申请提供的多畴像素结构的显示面板,通过将部分像素的主像素区和次像素区在位置上按照一定顺序翻转,有利于在中低灰阶次像素区发光微弱甚至无法亮起时,增加发光位置(主像素区)的无序度,从而达到提高显示面板发光均匀度的目的,进而提高画面的细腻度。
综上所述,虽然本申请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申请,本领域的普通技术人员,在不脱离本申请的精神和范围内,均可作各种更动与润饰,因此本申请的保护范围以权利要求界定的范围为准。
