可以理解,尽管第一、第二等这些术语可以在这里使用来描述各种元件、组件、区域、层和/或部分,但这些元件、组件、区域、层和/或部分不应仅限于这些术语。这些术语只是被用来区分元件、组件、区域、层和/或部分与另外的元件、组件、区域、层和/或部分。因此,只要不脱离本发明的教导,下面所讨论的第一部分、组件、区域、层和/或部分可以被称为第二元件、组件、区域、层和/或部分。
这里所用的专有名词仅用于描述特定的实施例而并非意图限定本发明。如这里所用的,单数形式“一”、“一个”和“该”也意图涵盖复数形式,除非上下文清楚指明是其它情况。还应该理解,当在说明书中使用术语“包含”、“包括”时,指明了所述特征、整体、步骤、操作、元件和/或部件的存在,但是不排除一个或多个其它特征、整体、步骤、操作、元件和/或部件的存在。
这里参考剖面图描述本发明的实施例,这些剖面图是本发明理想化的实施例(和中间构造)的示意图。因而,由于制造工艺和/或公差而导致的图示的形状不同是可以预见的。因此,本发明的实施例不应解释为限于这里图示的区域的特定形状,而应包括例如由于制造而产生的形状的偏差。图中所示的区域本身仅是示意性的,它们的形状并非用于图示装置的实际形状,并且并非用于限制本发明的范围。
除非另外定义,这里所使用的所有术语(包括技术和科学术语)具有与本发明所述领域的普通技术人员所通常理解的含义相同的含义。还应当理解,比如在通用的辞典中所定义的那些的术语,应解释为具有与它们在相关领域的环境中的含义相一致的含义,而不应以过度理想化或过度正式的含义来解释,除非在本文中明确地定义。
第一实施例
请参阅图1所示的本发明第一实施例的显示面板100。所述显示面板100大致成矩形,其定义有多个红色子像素11、多个绿色子像素12、多个蓝色子像素13和多个白色子像素14。其中,该显示面板100中所述红色子像素11和所述绿色子像素12的个数相等,且所述蓝色子像素13和所述白色子像素14的个数均少于所述红色子像素11或所述绿色子像素12的个数,且大致为所述红色子像素11或所述绿色子像素12的个数的一半。所述多个红色子像素11呈多列(列沿图1所示的D1方向)排布,红色子像素11所在的列中无其它颜色子像素,每一列红色子像素11中的多个红色子像素11沿第一方向D1依次邻接排布。所述多个绿色子像素12呈多列(列沿图1所示的D 1方向)排布,绿色子像素12所在的列中无其它颜色子像素,每一列绿色子像素12中的多个绿色子像素12沿第一方向D 1依次邻接排布。所述多个蓝色子像素13和多个白色子像素14则混合排布在相同的多列(列沿图1所示的D 1方向)中,且在同一列中蓝色子像素13和白色子像素14沿第一方向D1交替排布,在所述蓝色子像素和白色子像素的混合列中无红色子像素11和绿色子像素12。沿第二方向D2(与第一方向D 1交叉,本实施例中为垂直于第一方向D 1),所述红色子像素的列、所述绿色子像素的列、所述蓝色子像素和白色子像素的混合列为依次交替、周期性排布。
本实施例中,每个红色子像素11、每个绿色子像素12、每个蓝色子像素13和每个白色子像素14均大致呈矩形,且形状、尺寸大小大致相当。在其他实施例中,每个颜色的子像素的形状、尺寸可不限于此。
沿图1所示的D2方向,所述完整的红色子像素11和完整的绿色子像素12排布成多行(沿第二方向D2)。具有完整的红色子像素11和完整的绿色子像素12的行中,还设置有多个1/2个蓝色子像素13和多个1/2个白色子像素14。具有完整的红色子像素11和完整的绿色子像素12的行中,红色子像素11和绿色子像素12为沿第二方向D2交替排布,每一个红色子像素11与一个绿色子像素12为相邻的且沿第一方向D1为上下对齐设置;具有完整的红色子像素11和完整的绿色子像素12的行中,每一个绿色子像素12不与其相邻的蓝色子像素13或白色子像素14沿第一方向D1上下对齐,每一个绿色子像素12紧邻且对应1/2个蓝色子像素13和1/2个白色子像素14。每一具有红色子像素11和绿色子像素12的行中,红色子像素11、绿色子像素12、沿第一方向D1相邻的1/2个蓝色子像素13和1/2个白色子像素14的总和为沿第二方向D2依次交替、周期性排布。
可以理解的,所述子像素的排布不限于图1所示,还可进行调整,如将红色子像素11和绿色子像素12的位置进行互换;如将蓝色子像素13和白色子像素14的位置进行互换。
本实施例中,如去除掉所有红色子像素11和所有绿色子像素12来看,所有的白色子像素14间隔排布成多行(行沿图1所示的第二方向D2),所有的蓝色子像素13也间隔排布成多行(行沿图1所示的第二方向D2)。具有白色子像素14的行包含间隔排布的多个白色子像素14但不包含蓝色子像素13,具有蓝色子像素13的行包含间隔排布的多个蓝色子像素但不包含白色子像素14,且白色子像素14的行与蓝色子像素13的行为沿第一方向D 1依次交替、邻接排布。此外,具有完整的红色子像素11和完整的绿色子像素12的行与具有完整的白色子像素14的行为沿第一方向D 1上下不对齐;具有完整的红色子像素11和完整的绿色子像素12的行与具有完整的蓝色子像素13的行为沿第一方向D 1上下不对齐。
所述显示面板100定义有多个像素单元20,所述多个像素单元20成矩阵排布。如图1所示,每一个像素单元20(如虚线框所示)大致呈矩形,其包括位于同一行中相邻的一个红色子像素11和一个绿色子像素12,以及与该绿色子像素12或该红色子像素11相邻的1/2个蓝色子像素13和1/2个白色子像素14。即,所述每一个像素单元20与其沿第一方向D 1相邻的一个像素单元20共用一个蓝色子像素13,每一个像素单元20与其沿第一方向D 1相邻的另一个像素单元20共用一个白色子像素14。
可以理解的,图1中仅示意性的示出4×4矩阵排布的像素单元20,实际的显示面板包含的像素单元的行数和列数可能不限于此。
请参阅图2,所述显示面板100包括沿第一方向D 1延伸的多条数据线111及沿第二方向D2延伸的多条扫描线113。每相邻的两条数据线111与相邻的两条扫描线113相交定义出一个子像素区域30,所述多条数据线111及所述多条扫描线113相交定义出多个子像素区域30。沿第二方向D2相邻的三个子像素区域30构成上述的一个像素单元20。每一个每个红色子像素11对应一个子像素区域30,每个绿色子像素12对应一个子像素区域30、每1/2个蓝色子像素13与其相邻的1/2个白色子像素14共同对应一个子像素区域30。
如图2所示,该显示面板100还包括多个像素电极110。每一个像素电极110对应一个颜色的子像素,其中对应红色子像素11的像素电极110定义为红色像素电极110R,对应绿色子像素12的像素电极110定义为绿色像素电极110G,对应蓝色子像素13的像素电极110定义为蓝色像素电极110B,对应白色子像素14的像素电极110定义为白色像素电极110W。其中,每一个红色像素电极110R对应位于一个子像素区域30中,每一个绿色像素电极110G对应位于另一个子像素区域30中,每一个蓝色像素电极110B位于第一方向D 1相邻的两个子像素区域30中,每一个白色像素电极110W位于第一方向D 1相邻的两个子像素区域30中。由于像素电极110与子像素为一一对应的关系,所述多个像素电极110的排布与上述子像素的排布的方式、规律完全相同,由于上面已对子像素的排布进行了详细说明,此处就不再赘述。
如图2所示,所述蓝色像素电极110B被扫描线113于蓝色像素电极110B的投影贯穿并分成两相等的部分分别属于相邻的两个像素单元20;所述白色像素电极110W被扫描线113于白色像素电极110W的投影贯穿并分成两相等的部分分别属于相邻的两个像素单元20。
请继续参阅图2,每一个子像素区域30中设置有一个薄膜晶体管(TFT)120,每一个TFT120具有一个栅极121、一个源极123和一个漏极125。每一个TFT120的栅极121电性连接一条扫描线113,每一个TFT120的源极123电性连接一条数据线111,每一个TFT120的漏极125电性连接一个颜色的像素电极110。每一个红色像素电极110R电性连接一个TFT120(如过孔连接TFT120的漏极125),每一个绿色像素电极110G电性连接一个TFT120(如过孔连接TFT120的漏极125)。由于同一蓝色子像素13被相邻的两个像素单元20共用(位于最外边缘的蓝色子像素13除外),因此同一蓝色像素电极110B也被相邻的两个像素单元20共用。被相邻的两个像素单元20共用的一蓝色像素电极110B电性连接同一TFT120(如过孔连接TFT120的漏极125),且采用同一电极材料块制成,也即一个蓝色像素电极110B电性连接同一TFT120。由于同一白色子像素14被相邻的两个像素单元20共用(位于最外边缘的白色子像素14除外),因此同一白色像素电极110W也被相邻的两个像素单元20共用。被相邻的两个像素单元20共用的一白色像素电极110W电性连接同一TFT120(如过孔连接TFT120的漏极125),且采用同一电极材料块制成,也即一个白色像素电极110W电性连接同一TFT120。
第二实施例
请参阅图3,本发明第二实施例的显示面板200包括多个红色子像素11、多个绿色子像素12、多个蓝色子像素13和多个白色子像素14。本发明第二实施例的子像素的结构、排布情况与第一实施方式的子像素的结构、排布情况相似,唯一的区别在于:第一实施例中,沿第二方向D2,具有完整的白色子像素14的行不包含蓝色子像素13,具有完整的蓝色子像素13的行不包含白色子像素14;而第二实施例中,沿第二方向D2,具有完整的白色子像素14的行包含蓝色子像素13,且蓝色子像素13和白色子像素14为依次交替排布。
即,本实施例中,假如去除掉所有红色子像素11和所有绿色子像素12来看,所有的白色子像素14和所有的蓝色子像素13混合排布成多行(行沿图3所示的第二方向D2)和多列(行沿图1所示的第一方向D1)。具有完整的白色子像素14和完整的蓝色子像素13的混合列中,白色子像素14和蓝色子像素13依次交替、邻接排布。具有完整的白色子像素14和完整的蓝色子像素13的混合行中,白色子像素14和蓝色子像素13依次交替且间隔排布。
可以理解的,所述子像素的排布不限于图3所示,还可进行调整,如将红色子像素和绿色子像素的位置进行互换;如将白色子像素和蓝色子像素的位置进行互换。
所述显示面板200定义有多个像素单元20。每一个像素单元20(如虚线框所示)大致呈矩形,其包括位于同一行中相邻的一个红色子像素11和一个绿色子像素12,以及与该绿色子像素12相邻的1/2个蓝色子像素13和1/2个白色子像素14。即,所述每一个像素单元20与其沿第一方向D 1相邻的一个像素单元20共用一个蓝色子像素13,每一个像素单元20与其沿第一方向D 1相邻的另一个像素单元20共用一个白色子像素14。
请参阅图4,所述显示面板200包括沿第一方向D 1延伸的多条数据线111及沿第二方向D2延伸的多条扫描线113。每相邻的两条数据线111与相邻的两条扫描线113相交定义出一个子像素区域30,所述多条数据线111及所述多条扫描线113相交定义出多个子像素区域30。沿第二方向D2相邻的三个子像素区域30构成上述的一个像素单元20。每一个每个红色子像素11对应一个子像素区域30,每个绿色子像素12对应一个子像素区域30、每1/2个蓝色子像素13与其相邻的1/2个白色子像素14对应一个子像素区域30。
如图4所示,该显示面板200还包括多个像素电极110。每一个像素电极110对应一个颜色的子像素,其中对应红色子像素11的像素电极110为红色像素电极110R,对应绿色子像素12的像素电极110为绿色像素电极110G,对应蓝色子像素13的像素电极110为蓝色像素电极110B,对应白色子像素14的像素电极110为白色像素电极110W。每一个红色像素电极110R对应位于一个子像素区域30中,每一个绿色像素电极110G对应位于另一个子像素区域中,每一个蓝色像素电极110B位于第一方向D 1相邻的两个子像素区域中,每一个白色像素电极110W位于第一方向D 1相邻的两个子像素区域中。所述多个像素电极的排布与上述子像素的排布的方式完全相同。由于像素电极110与子像素为一一对应的关系,所述多个像素电极110的排布与上述子像素的排布的方式、规律完全相同。由于上面已对子像素的排布进行了详细说明,此处就不再赘述。
如图4所示,所述蓝色像素电极110B被扫描线113于蓝色像素电极110B的投影贯穿;所述白色像素电极110W被扫描线113于白色像素电极110W的投影贯穿。
请参阅图4,每一个子像素区域30中设置有一个薄膜晶体管120,每一个薄膜晶体管120具有一个栅极121、一个源极123和一个漏极125。每一个薄膜晶体管120的栅极121电性连接一条扫描线113,每一个薄膜晶体管120的源极123电性连接一条数据线111,每一个薄膜晶体管120的漏极125电性连接一个颜色的像素电极110。如图4所示,每一个红色像素电极110R电性连接一个TFT120(如过孔连接TFT120的漏极125),每一个绿色像素电极110G电性连接一个TFT120(如过孔连接TFT120的漏极125)。由于同一蓝色子像素13被相邻的两个像素单元20共用(位于最外边缘的蓝色子像素13除外),因此同一蓝色像素电极110B也被相邻的两个像素单元20共用。被相邻的两个像素单元20共用的一蓝色像素电极110B电性连接同一TFT120(如过孔连接TFT120的漏极125),且采用同一电极材料块制成,也即一个蓝色像素电极110B电性连接同一TFT120。由于同一白色子像素14被相邻的两个像素单元20共用(位于最外边缘的白色子像素14除外),因此同一白色像素电极110W也被相邻的两个像素单元20共用。被相邻的两个像素单元20共用的一白色像素电极110W电性连接同一TFT120(如过孔连接TFT120的漏极125),且采用同一电极材料块制成,也即一个白色像素电极110W电性连接同一TFT120。
请参阅图5,本实施例中,所述显示面板100,200为液晶显示面板,所述显示面板包括TFT阵列基板101、与TFT阵列基板101相对设置的对向基板102、以及设置在所述TFT阵列基板101与所述对向基板102之间的液晶层103。
可以理解的,所述显示面板100,200不限于液晶显示面板,还可为其他的显示面板,只要保证显示面板的子像素的排布满足上述要求即可。
本发明对不同颜色的子像素的排布进行调整,使每一个像素单元均中具有蓝色子像素和白色子像素,且相邻像素单元中蓝色子像素和白色子像素的对称性较好,能够有效避免伪影(image artifact)的产生。
以上实施例仅用以说明本发明的技术方案而非限制,图示中出现的上、下、左及右方向仅为了方便理解,尽管参照较佳实施例对本发明进行了详细说明,本领域的普通技术人员应当理解,可以对本发明的技术方案进行修改或等同替换,而不脱离本发明技术方案的精神和范围。
