技术领域
本公开文本涉及显示技术领域，尤其涉及一种像素结构和显示装置。
背景技术
OLED，即有机发光二极管(Organic Light-Emitting Diode)，又称为有机电激光显示(Organic Electroluminesence Display，OELD)。OLED具有自发光的特性，采用非常薄的有机材料涂层和玻璃基板，当电流通过时，有机材料就会发光，而且OLED显示屏幕可视角度大，可以实现柔性化，并且能够显著节省电能，因此OLED显示屏幕具备了许多LCD(Liquid Crystal Display，液晶显示器)不可比拟的优势。
传统的应用于OLED显示屏幕上的是平行排布的矩形像素结构，如图1A所示，每个像素单元包括从左至右依次排列的矩形的红色亚像素R、绿色亚像素G和蓝色亚像素B，红色亚像素R和绿色亚像素G之间有一个邻接边，绿色亚像素G和蓝色亚像素B之间有一个邻接边，但是红色亚像素R和蓝色亚像素B之间并不相邻设置，因此传统的平行排布的矩形像素结构的每个像素单元中的各个亚像素之间的混光效果不好，导致OLED显示屏幕上的画面画质较低。图1B是该矩形像素结构包括的像素单元的阵列布线示意图，GL指示的是为红色亚像素R、绿色亚像素G和蓝色亚像素B提供扫描信号的栅线，DL1指示的是为红色亚像素R提供数据的第一数据线，DL2指示的是为绿色亚像素G提供数据的第二数据线，DL3指示的是为蓝色亚像素B提供数据的第三数据线。

具体实施方式
本公开文本实施例所述的像素结构包括多个像素单元，每一个像素单元包括：
第一颜色的第一亚像素，具有第一长度的第一邻接边和第二长度的第二邻接边；
第二颜色的第二亚像素，具有第一长度的第一邻接边和第三长度的第二邻接边；
以及，第三颜色的第三亚像素，具有第二长度的第一邻接边和第三长度的第二邻接边；
在每一个像素单元中，所述第一亚像素的第一邻接边和所述第二亚像素的第一邻接边相邻设置，所述第一亚像素的第二邻接边和所述第三亚像素的第一邻接边相邻设置，所述第二亚像素的第二邻接边和所述第三亚像素的第二邻接边相邻设置。
与现有的排布规律性高的平行排布的矩形像素结构相比，本公开文本实施例所述的像素结构中像素单元的每两个亚像素之间都有邻接边，从而提高了每个像素单元内部各个亚像素之间的混光效果，从而提高显示画面的画质。
优选的，在本公开文本实施例所述的像素结构中，每一个像素单元包括的至少一个亚像素与至少4个与该亚像素颜色不同的亚像素具有部分或全部相邻设置的邻接边，相对于现有的平行排布的矩形像素结构的每个亚像素只与两个与其颜色不同的亚像素具有相邻设置的邻接边，本公开文本实施例所述的像素结构提高了整个像素结构内部的各个亚像素之间的混光效果，进一步提高了显示画面的画质。
具体的，本公开文本实施例所述的像素结构应用于OLED显示装置，所述第一亚像素为绿色亚像素G，所述第二亚像素为红色亚像素R，所述第三亚像素为蓝色亚像素B；
所述绿色亚像素G的面积小于所述红色亚像素R的面积和所述蓝色亚像素B的面积。
在现有的OLED显示装置中，蓝色亚像素的发光效率较低，红色亚像素的光通量衰减较为强烈，绿色亚像素的发光效率较高，人眼对绿色亚像素的感知度较高，但是由于现有的像素结构的蓝色亚像素的面积与红色亚像素的面积和绿色亚像素的面积相等，因此只能通过调节信号对比度的方法，对色偏进行校正，但此种信号补偿的方法局限性较大。同时由于红色亚像素的光通量衰减较为强烈，因此也需要对红光亮度进行补偿，而绿色亚像素的发光效率较高，人眼对绿色亚像素的感知度较高。针对上述问题，本公开文本实 施例所述的像素结构通过调整红色亚像素的面积和蓝色亚像素的面积大于绿色亚像素的面积，通过增大红光亚像素和蓝光亚像素的面积比例，可以更为直接简便的校正色偏，同时也提高了通过调节信号来调节色偏的可调节范围。
优选的，所述红色亚像素的面积和所述绿色亚像素的面积之比为1.4至1.6；所述蓝色亚像素的面积和所述绿色亚像素的面积之比为1.4至1.6，采用如上的面积比例可以使得OLED显示装置的色偏校正效果较好。
下面通过三个实施例来具体介绍本公开文本所述的像素结构。
实施例一
如图2A所示，所述像素单元包括红色亚像素R、绿色亚像素G和蓝色亚像素B，其中，
所述绿色亚像素G为正方形；
所述红色亚像素R和所述蓝色亚像素B为直角梯形；所述红色亚像素R的大小和所述蓝色亚像素B的大小相同；
所述红色亚像素R的第一邻接边为该红色亚像素R的上底边，所述红色亚像素R的第二邻接边为该红色亚像素R的斜边；
所述蓝色亚像素B的第一邻接边为该蓝色亚像素B的上底边，所述蓝色亚像素B的第二邻接边为该蓝色亚像素B的斜边；
红色亚像素R、绿色亚像素G和蓝色亚像素B组成的所述像素单元为正方形；
所述绿色亚像素G的面积、所述红色亚像素R的面积和所述蓝色亚像素B的面积的比例为1∶1.5∶1.5。
在具体实施时，所述绿色亚像素G的面积、所述红色亚像素R的面积和所述蓝色亚像素B的面积也可以被设置为1∶1.6∶1.6，基于对现有的红色亚像素R的光通量衰减程度、蓝色亚像素B的发光效率以及绿色亚像素G的发光效率，采用这样的亚像素面积比例也可以使得色偏校正的效果较好。
在如图2A所示的像素单元中，绿色亚像素G与红色亚像素R之间的邻接边的长度为L1，绿色亚像素G与蓝色亚像素B之间的邻接边的长度为L3，红色亚像素R与蓝色亚像素B之间的邻接边的长度为L2，在实际操作时，亚像素之间采用黑矩阵隔离，因此本公开文本该实施例所述的像素结构的每个 像素单元中的黑色矩阵的长度L为L1+L2+L3，该长度L小于现有的平行排列的矩形像素结构中的每个像素单元中的黑色矩阵长度，因此本公开文本该实施例的像素结构的像素单元的开口率大于现有的平行排列的矩形像素结构的像素单元的开口率。
对如图2A所示的本公开文本该实施例所述的像素结构包括的像素单元和如图1A所示的现有的像素单元进行光学模拟的结果如下：
在本公开文本该实施例所述的像素结构包括的像素单元中，像素单元的边长为a，亚像素之间的黑矩阵区域的宽度为0.04a(该黑矩阵区域不透光)，边界区域的宽度为0.02a(该边界区域的透光率为50％)，其他的区域发光均匀，经过光学模拟后得到该像素单元的开口率为67.48％；
在现有的像素结构包括的像素单元中，像素单元的边长为a，亚像素之间的黑矩阵区域的宽度为0.04a(该黑矩阵区域不透光)，边界区域的宽度为0.02a(该边界区域的透光率为50％)，其他的区域发光均匀，经过光学模拟后得到该像素单元的开口率为65.154％；
由上可知，本公开文本该实施例的像素结构的像素单元的开口率大于现有的平行排列的矩形像素结构的像素单元的开口率。
并且，相对于现有的可以使得人眼能够清晰的辨析出的亚像素规律排布的平行排列的矩形像素结构，本公开文本如图2A所示的像素结构的实施例中的亚像素的排布具有更高的无序性，从而可以降低人眼分辨亚像素的能力，从而提高显示画面的画质。
并且，在如图2A所示的实施例中，各个亚像素的形状更趋于正方形，因此亚像素的主发光区域相较现有的像素结构的矩形亚像素的主发光区域更大，该实施例的亚像素的区域中心比较现有的矩形亚像素的区域中心更远离边界发光区域，因此发光效率更高，发光层的蒸镀可以更均匀(在OLED的发光层的制作过程中，往往无法使得每一个亚像素的每一块面积都可以均匀的发光，通常是亚像素中心区域的发光效果较好、发光效率较高，而周边的边界区域往往发光效率较低，因此提高了中心的主发光区域的面积，而缩小了边界发光区域的面积)。
图2B是该实施例所述的像素结构包括的像素单元的阵列布线示意图，从 图2B可以看出，该实施例所述的像素结构采用和现有的像素结构相近似的阵列布线方式，但图2B中的栅线GL的位置较传统结构更高(从三个亚像素共有区域经过)。在图2B中，GL指示的是为红色亚像素R、绿色亚像素G和蓝色亚像素B提供扫描信号的栅线，DL1指示的是为红色亚像素R提供数据的第一数据线，DL2指示的是为绿色亚像素G提供数据的第二数据线，DL3指示的是为蓝色亚像素B提供数据的第三数据线。
图2C是由如图2A所示的像素单元组成的像素阵列，在该像素阵列中，每一个像素单元包括的至少一个亚像素与至少4个与该亚像素颜色不同的亚像素具有部分或全部相邻设置的邻接边，提高了像素阵列中各个亚像素之间的混光效果，进一步提高了显示画面的画质。
实施例二
如图3A所示，所述像素单元包括红色亚像素R、绿色亚像素G和蓝色亚像素B，其中，
所述绿色亚像素G为正方形；所述红色亚像素R和所述蓝色亚像素B为具有三个直角的五边形；所述红色亚像素R的大小和所述蓝色亚像素B的大小相同；
所述红色亚像素R的第一边为该红色亚像素R的第一邻接边，所述红色亚像素R的第二边为该红色亚像素R的第二邻接边，该第一边的第一端与该第二边的第一端连接，该第一边与该第二边的夹角为135度；所述红色亚像素R的第三边的第一端与该第二边的第二端连接，该第三边和该第二边的夹角为135度；所述红色亚像素R的第四边的第一端与该第一边的第二端连接，该第四边的长度与该第一边的长度相等；
所述蓝色亚像素B的第一边为该蓝色亚像素B的第一邻接边，所述蓝色亚像素B的第二边为该蓝色亚像素B的第二邻接边，该第一边的第一端与该第二边的第一端连接，该第一边与该第二边的夹角为135度；所述蓝色亚像素B的第三边的第一端与该第二边的第二端连接，该第三边和该第二边的夹角为135度；所述蓝色亚像素B的第四边的第一端与该第一边的第二端连接，该第四边的长度与该第一边的长度相等；
所述绿色亚像素G的面积、所述红色亚像素R的面积和所述蓝色亚像素 B的面积的比例为1∶1.4∶1.4。
实施例二与实施例一相比，区别仅在于去除了红色亚像素R和蓝色亚像素B的发光效率低的尖角结构，从而提升了像素单元整体的发光效率，由于蓝色亚像素B发光效率低，红色亚像素R的光通量衰减较强烈而人眼对绿色亚像素G的感知度高，因此为了兼顾色偏校正的效果，在实施例二中，将所述绿色亚像素G的面积、所述红色亚像素R的面积和所述蓝色亚像素B的面积的比例设置为1∶1.4∶1.4。
图3B是实施例二所述的像素结构包括的像素单元的阵列布线示意图，从图3B可以看出，该实施例所述的像素结构采用和现有的像素结构相近似的阵列布线方式，但图3B中的栅线GL的位置较传统结构更高(从三个亚像素共有区域经过)。在图3B中，GL指示的是为红色亚像素R、绿色亚像素G和蓝色亚像素B提供扫描信号的栅线，DL1指示的是为红色亚像素R提供数据的第一数据线，DL2指示的是为绿色亚像素G提供数据的第二数据线，DL3指示的是为蓝色亚像素B提供数据的第三数据线。
图3C是由如图3A所示的像素单元组成的像素阵列，在该像素阵列中，每一个像素单元包括的至少一个亚像素与至少4个与该亚像素颜色不同的亚像素具有部分或全部相邻设置的邻接边，提高了像素阵列中各个亚像素之间的混光效果，进一步提高了显示画面的画质。
在实际操作时，显示面板的像素显示区的边界区域采用黑矩阵进行填充。
实施例三
如图4A所示，所述像素单元包括红色亚像素R、绿色亚像素G和蓝色亚像素B，其中，
所述绿色亚像素G为正方形；所述红色亚像素R和所述蓝色亚像素B为具有三个直角的五边形；所述红色亚像素R的大小和所述蓝色亚像素B的大小相同；所述第一长度、所述第二长度和所述第三长度相等；
所述红色亚像素R的第一边为该红色亚像素R的第一邻接边，所述红色亚像素R的第二边为该红色亚像素R的第二邻接边，该第一边的第一端与该第二边的第一端连接，该第一边与该第二边的夹角为135度；该第二边的第二端与所述红色亚像素R的第三边的第一端连接，该第三边和该第二边之间 的夹角为直角；该第三边的第二端与所述红色亚像素R的第四边的第一端连接，该第四边与该第三边之间的夹角为直角；该第四边的第二端与所述红色亚像素R的第五边的第一端连接，该第五边与该第四边的夹角为135度；
所述蓝色亚像素B的第一边为该蓝色亚像素B的第一邻接边，所述蓝色亚像素B的第二边为该蓝色亚像素B的第二邻接边，该第一边的第一端与该第二边的第一端连接，该第一边与该第二边的夹角为135度；该第二边的第二端与所述蓝色亚像素B的第三边的第一端连接，该第三边和该第二边之间的夹角为直角；该第三边的第二端与所述蓝色亚像素B的第四边的第一端连接，该第四边与该第三边之间的夹角为直角；该第四边的第二端与所述蓝色亚像素B的第五边的第一端连接，该第五边与该第四边的夹角为135度；
所述红色亚像素R、所述绿色亚像素G和所述蓝色亚像素B组成的像素单元为带两个倒角的三角形；
所述绿色亚像素G的面积、所述红色亚像素R的面积和所述蓝色亚像素B的面积的比例为1∶1.4∶1.4。
在如图4A所示的像素单元中，绿色亚像素G与红色亚像素R之间的邻接边的长度为L1，绿色亚像素G与蓝色亚像素B之间的邻接边的长度为L3，红色亚像素R与蓝色亚像素B之间的邻接边的长度为L2，在实际操作时，亚像素之间采用黑矩阵隔离，因此本公开文本该实施例所述的像素结构的每个像素单元中的黑色矩阵的长度L为L1+L2+L3，该长度L小于现有的平行排列的矩形像素结构中的每个像素单元中的黑色矩阵长度，因此本公开文本该实施例的像素结构的像素单元的开口率大于现有的平行排列的矩形像素结构的像素单元的开口率。
在实施例三中，各个亚像素的形状更趋于正方形，因此亚像素的主发光区域相较现有的像素结构的矩形亚像素的主发光区域更大，该实施例的亚像素的区域中心比较现有的矩形亚像素的区域中心更远离边界发光区域，因此发光效率更高，发光层的蒸镀可以更均匀(在OLED的发光层的制作过程中，往往无法使得每一个亚像素的每一块面积都可以均匀的发光，通常是亚像素中心区域的发光效果较好、发光效率较高，而周边的边界区域往往发光效果较低，因此提高了中心的主发光区域的面积，而缩小了边界发光区域的面积)
图4B是该实施例所述的像素结构包括的像素单元的阵列布线示意图，从图4B可以看出，该实施例所述的像素结构采用和现有的像素结构相近似的阵列布线方式，但图4B中的栅线GL的位置较传统结构更高(从三个亚像素共有区域经过)。在图4B中，GL指示的是为红色亚像素R、绿色亚像素G和蓝色亚像素B提供扫描信号的栅线，DL1指示的是为红色亚像素R提供数据的第一数据线，DL2指示的是为绿色亚像素G提供数据的第二数据线，DL3指示的是为蓝色亚像素B提供数据的第三数据线。
图4C是由如图4A所示的像素单元组成的像素阵列，在该像素阵列中，每一个像素单元包括的至少一个亚像素与至少4个与该亚像素颜色不同的亚像素具有部分或全部相邻设置的邻接边，提高了像素阵列中各个亚像素之间的混光效果，进一步提高了显示画面的画质。
实施例三去除了红色亚像素R和蓝色亚像素B的发光效率低的尖角结构，从而提升了像素单元的发光效率，由于蓝色亚像素B发光效率低，红色亚像素R的光通量衰减较强烈而人眼对绿色亚像素G的感知度高，因此为了兼顾色偏校正的效果，在实施例三中，将所述绿色亚像素G的面积、所述红色亚像素R的面积和所述蓝色亚像素B的面积的比例设置为1∶1.4∶1.4。
本公开文本还提供了一种显示装置，包括上述的像素结构。优选的，所述显示装置可以为OLED显示装置。
以上所述是本公开文本的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本公开文本所述原理的前提下，还可以作出若干改进和润饰，这些改进和润饰也应视为本公开文本的保护范围。
