Description

像素单元及显示装置
本申请要求享有2016年7月18日提交的名称为“像素单元及显示装置”的中国专利申请CN201610563495.8的优先权，其全部内容通过引用并入本文中。
技术领域
本发明涉及显示技术领域，具体的说，涉及一种像素单元及显示装置。
背景技术
随着显示技术的发展，有机发光二极管(Organic Light-Emitting Diode，简称OLED)显示器的技术日见成熟，已经越来越多的应用在各个显示领域。
OLED显示器通过薄膜晶体管(Thin Film Transistor，简称TFT)对各个子像素进行驱动。具体来说，每个子像素都配置有一个薄膜晶体管，使得每一个子像素可以独立的运作，且不易受到其他子像素的影响。
如图1所示，传统的OLED显示器中，每个像素单元由红色(R)、绿色(G)、蓝色(B)三个子像素10组成，像素单元阵列组成了整个显示区域。如图2所示，在另一种OLED显示器中，每个像素单元由四个子像素10组成，四个子像素10的颜色分别是红色(R)、绿色(G)、蓝色(B)、白色(W)，其中白色子像素主要起到调节像素单元亮度的作用。
从图1和图2中可以看出，阵列式排布的子像素10并不是紧密排列的，在子像素10的间隙都填充有黑矩阵(Black Matrix，简称BM)20，用于防止漏光，以及避免相邻的子像素的颜色互相干扰。随着当前对OLED显示器的分辨率的要求越来越高，子像素也越来越密集，但由于工艺的限制，黑矩阵的宽度不能减小，造成OLED显示器的开口率较低的技术问题。
发明内容
本发明的目的在于提供一种像素单元及显示装置，以解决现有的OLED显示器的开口率较低的技术问题。
本发明提供一种像素单元，包括两个不同颜色的子像素；
每个所述子像素均呈正六边形，且两个所述子像素共用一条边。
优选的是，两个所述子像素的颜色分别为红色和绿色；
或者两个所述子像素的颜色分别为蓝色和白色；
或者两个所述子像素的颜色分别为红色和白色；
或者两个所述子像素的颜色分别为蓝色和绿色。
本发明还提供一种显示装置，包括两种上述的像素单元，且两种所述像素单元中包含红色、绿色、蓝色、白色四种不同颜色的子像素。
进一步的是，一种像素单元中的两个子像素的颜色为红色和绿色，另一种像素单元中的两个子像素的颜色为蓝色和白色；
或者，一种像素单元中的两个子像素的颜色为红色和白色，另一种像素单元中的两个子像素的颜色为蓝色和绿色。
优选的是，所有像素单元中的两个子像素都沿相同的方向排列。
在一种实施方式中，在一个像素单元中的两个子像素的排列方向上，相邻的两个像素单元中具有不同颜色的子像素。
进一步的是，沿数据线延伸的列方向，同一列中的子像素颜色相同，且均由同一条数据线控制。
在另一种实施方式中，在一个像素单元中的两个子像素的排列方向上，相邻的两个像素单元中具有相同颜色的子像素。
进一步的是，沿数据线延伸的列方向，同一列中包括间隔排列的两种颜色不同的子像素，且分别由两条数据线控制。
优选的是，所述显示装置为有机发光二极管显示装置。
本发明带来了以下有益效果：本发明提供的像素单元由两个正六边形的子像素组成，而本发明提供的显示装置由上述像素单元组成，且包含四种不同颜色的子像素。由于每个子像素的形状都是正六边形，所以在显示装置的显示区域中，多个子像素可以呈蜂窝状排布。呈蜂窝状排布的正六边形子像素，在相同数量的子像素中，能够减少黑矩阵的总长度，因此在黑矩阵的宽度不变的情况下，减少了黑矩阵的面积，从而提高了显示装置的开口率，解决了现有技术中开口率较低的技术问题。
本发明的其它特征和优点将在随后的说明书中阐述，并且，部分的从说明书中变得显而易见，或者通过实施本发明而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
附图说明
为了更清楚的说明本发明实施例中的技术方案，下面将对实施例描述中所需要的附图做简单的介绍：
图1是现有的OLED显示器的像素排布的示意图；
图2是另一种现有的OLED显示器的像素排布的示意图；
图3是本发明实施例一提供的像素单元的示意图；
图4是本发明实施例二提供的显示装置中像素单元排布的示意图；
图5是本发明实施例二提供的显示装置中像素单元驱动的示意图；
图6是本发明实施例三提供的显示装置中像素单元排布的示意图；
图7是本发明实施例三提供的显示装置中像素单元驱动的示意图。
具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式，借此对本发明如何应用技术手段来解决技术问题，并达成技术效果的实现过程能充分理解并据以实施。需要说明的是，只要不构成冲突，本发明中的各个实施例以及各实施例中的各个特征可以相互结合，所形成的技术方案均在本发明的保护范围之内。
实施例一：
如图3所示，本发明实施例提供一种像素单元，包括两个不同颜色的子像素1。每个子像素1均呈正六边形，且两个子像素1共用一条边，即两个子像素1的一边相邻。
两个子像素的颜色优选为图3中所示的四种组合：两个子像素的颜色分别为红色和绿色，或者分别为蓝色和白色，或者分别为红色和白色，或者分别为蓝色和绿色。此外，每个子像素周边都形成有黑矩阵2。
本发明实施例提供的像素单元中的子像素为正六边形，所以多个子像素可以呈蜂窝状排布。呈蜂窝状排布的正六边形子像素，在相同数量的子像素中，能够减少黑矩阵的总长度，因此在黑矩阵的宽度不变的情况下，减少了黑矩阵的面积，从而提高了显示装置的开 口率，解决了现有技术中开口率较低的技术问题。
实施例二：
本发明实施例提供一种显示装置，优选为OLED显示装置。该显示装置包括两种上述实施例一提供的像素单元，且两种像素单元中包含红色、绿色、蓝色、白色四种不同颜色的子像素。
如图4所示，本实施例中，其中一种像素单元11中的两个子像素的颜色为红色和绿色，另一种像素单元12中的两个子像素的颜色为蓝色和白色。所有像素单元11、12中的两个子像素都沿相同的方向排列，从图4中可以看出，每个像素单元11、12中的两个子像素都是沿与竖直方向呈30°角的左下、右上位置排列。
本实施例中，在一个像素单元11、12中的两个子像素的排列方向上，即与竖直方向呈顺时针30°角的方向上，相邻的两个像素单元中具有不同颜色的子像素。也就是在该方向上间隔排布这两种像素单元11、12，并且子像素呈蜂窝状排布。在相同数量的子像素中，呈蜂窝状排布的正六边形子像素能够减少黑矩阵13的总长度，因此在黑矩阵13的宽度不变的情况下，减少了黑矩阵13的面积，从而提高了显示装置的开口率，解决了现有技术中开口率较低的技术问题。
如图5所示，沿数据线D延伸的列方向(图中的竖直方向)，同一列中的子像素颜色相同，并且同一列中的子像素均由同一条数据线D控制。将颜色相同的子像素用同一条数据线D控制，便于数据信号的生成和输出。另一方面，用于驱动各个像素单元的扫描线Gt设置在两行子像素之间的，并且一条扫描线Gt能够控制两行子像素，因此本发明实施例中能够减少扫描线的数量。
本发明实施例提供的显示装置中，采用两种像素单元，且每种像素单元个字具有两种颜色的子像素，共同组成红、绿、蓝、白四种颜色的显示区域。这样更有利于在显示中进行波瓦形(Pentile)算法，也就是一个像素单元会借用与其相邻的像素单元的另一种颜色，来构成三基色，从而提升了显示装置的虚拟分辨率，并且降低了显示装置的制造难度。
应当说明的是，本发明实施例提供的技术方案，并不仅限于应用在OLED显示装置中，也可以用于液晶显示器等其他类型的显示装置。
实施例三：
本发明实施例提供一种显示装置，优选为OLED显示装置。该显示装置包括两种上述实施例一提供的像素单元，且两种像素单元中包含红色、绿色、蓝色、白色四种不同颜色的子像素。
如图6所示，本实施例中，其中一种像素单元21中的两个子像素的颜色为红色和白色，另一种像素单元22中的两个子像素的颜色为蓝色和绿色。所有像素单元21、22中的两个子像素都沿相同的方向排列，从图4中可以看出，每个像素单元21、22中的两个子像素都是沿与竖直方向呈30°角的左下、右上位置排列。
本实施例中，在一个像素单元21、22中的两个子像素的排列方向上，即与竖直方向呈顺时针30°角的方向上，相邻的两个像素单元中具有相同颜色的子像素。也就是在该方向上排布的都有同一种像素单元21或像素单元22，并且子像素呈蜂窝状排布。在相同数量的子像素中，呈蜂窝状排布的正六边形子像素能够减少黑矩阵23的总长度，因此在黑矩阵23的宽度不变的情况下，减少了黑矩阵23的面积，从而提高了显示装置的开口率，解决了现有技术中开口率较低的技术问题。
如图7所示，沿数据线D延伸的列方向(图中的竖直方向)，同一列中包括间隔排列的两种颜色不同的子像素，并且同一列中的两种颜色的子像素分别由两条数据线D控制，也就是由两条数据线D分别控制同一列中的两种子像素。将颜色相同的子像素用同一条数据线D控制，便于数据信号的生成和输出。另一方面，用于驱动各个子像素单元的扫描线Gt设置在两行子像素之间的，并且一条扫描线Gt能够控制两行子像素，因此本发明实施例中能够减少扫描线的数量。
本发明实施例提供的显示装置中，采用两种像素单元，且每种像素单元个字具有两种颜色的子像素，共同组成红、绿、蓝、白四种颜色的显示区域。这样更有利于在显示中进行波瓦形(Pentile)算法，也就是一个像素单元会借用与其相邻的像素单元的另一种颜色，来构成三基色，从而提升了显示装置的虚拟分辨率，并且降低了显示装置的制造难度。
应当说明的是，本发明实施例提供的技术方案，并不仅限于应用在OLED显示装置中，也可以用于液晶显示器等其他类型的显示装置。
虽然本发明所公开的实施方式如上，但所述的内容只是为了便于理解本发明而采用的实施方式，并非用以限定本发明。任何本发明所属技术领域内的技术人员，在不脱离本发明所公开的精神和范围的前提下，可以在实施的形式上及细节上作任何的修改与变化，但本发明的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
