图1为一种OLED显示器件的结构示意图，如图1所示，在垂直于OLED显示器件的方向，该OLED显示器件可以包括：衬底基板10、设置在衬底基板10上的像素驱动电路11以及设置在像素驱动电路11的远离衬底基板10 的一侧的像素结构。例如，像素驱动电路11可以包括多个像素电路，分别被配置为驱动后续形成的像素结构中的多个发光元件12。像素电路的电路结构及布局可以根据实际情况进行设计，本公开实施例对此不作限定。为了清晰和简洁，图1中仅示意性地示出了像素驱动电路11中每一个像素电路中的一个晶体管T1，该晶体管T1被配置为与后续形成的发光元件12耦接。例如，像素驱动电路11还可以包括扫描信号线和数据信号线等多种走线，本公开实施例对此不作限定。例如，衬底基板10可以为硅基衬底基板，如单晶硅衬底基板，但不限于此。
在一种示例性实施例中，如图1所示，以晶体管T1为例，像素驱动电路11中的晶体管T1可以包括栅电极G、源电极S和漏电极D。例如，该三个电极分别与三个电极连接部电连接，例如通过钨金属填充的过孔(即钨过孔，W-via)进行电连接；进而，该三个电极可以分别通过对应的电极连接部与其他电学结构(例如，晶体管、走线或者发光元件等)进行电连接。
在一种示例性实施例中，如图1所示，在垂直于OLED显示器件的方向，该OLED显示器件可以包括：形成在像素驱动电路11之上的多个发光元件12。例如，发光元件12可以包括依次叠设的第一电极121(例如，作为阳极)、有机发光功能层122和第二电极123(例如，作为阴极)。例如，第一电极121可以通过钨过孔与对应的晶体管T1的源电极S电连接(经由源电极S对应的连接部)，这里，源电极S和漏电极D的位置可以互换，即第一电极121可以换成与漏电极D电连接。例如，有机发光功能层122可以包括发光(Emitted-Light，EL)层，还可以包括电子注入层、电子传输层、空穴注入层和空穴传输层中的一种或多种。例如，第二电极123可以为透明电极。例如，第二电极123可以为公共电极，即像素结构中的多个发光元件12可以共用一整面的第二电极123。
在一种示例性实施例中，如图1所示，在垂直于OLED显示器件的方向，该OLED显示器件还可以包括：依次设置在多个发光元件12之上的第一封装层13、彩色滤光层15和第二封装层14。例如，彩色滤光层15可以包括：多个彩色滤光片(Color Filter，CF)151以及位于相邻的彩色滤光片151之间的黑矩阵(Black Matric，BM)152，其中，多个彩色滤光片151与像素结 构中的多个发光元件相对应，被配置为使发光元件发出的光透过，一个彩色滤光片151与对应的一个发光元件可以划分为一个子像素。例如，彩色滤光片151可以包括红色(R)滤光单元、绿色(G)滤光单元和蓝色(B)滤光单元。其中，红色(R)滤光单元、绿色(G)滤光单元和蓝色(B)滤光单元可以分别对应于红色(R)子像素、绿色(G)子像素和蓝色(B)子像素。例如，彩色滤光片151的材料可以为彩色光刻胶(或者，可简称为彩胶)，但不限于此。例如，第一封装层13和第二封装层14可以为聚合物和陶瓷薄膜封装(Thin Film Encapsulation，TFE)层中的任意一种或多种，但不限于此。
在一种示例性实施例中，该OLED显示器件还可以包括：设置在第二封装层14的远离衬底基板10的一侧的盖板16。例如，盖板16可以为玻璃盖板，但不限于此。
在一种示例性实施例中，以第一封装层13和第二封装层14为TFE层为例，因OLED材料及阴极(Cathode，一般材料为Mg/Ag)材料对水(H2O)和氧气(O2)敏感(即易被氧化)，TFE层可对OLED显示器件进行保护。如此，使用薄膜封装技术隔绝水氧，可起到保护OLED显示器件的效果。
一方面，如图1所示，一些OLED显示器件(例如，Micro OLED显示器件)通常是采用发射白光的发光层加上CF 151来实现彩色显示的。其中，CF 151是通过对特定波长的光进行吸收，来实现“单色光”透过的(例如，实现单色红光、单色蓝光或者单色绿光通过)，因此，OLED显示器件中白光的发光层发出的白光透过CF 151后，亮度会大幅度下降。目前的一些OLED显示器件(例如，Micro OLED显示器件)中所使用的低温CF 151的透过率约在18％至30％之间，有效显示区(Active Area，AA)区中阳极(Anode)的开口率(Aperture Ratio，AR)约在60％至70％之间，那么，根据如下公式(1)可以计算得知，目前的一些OLED显示器件(例如，Micro OLED显示器件)中的发光层所发出的白光中大约只有1/4得到有效利用。因此，CF 151的低透过率是导致一些OLED显示器件(例如，Micro OLED显示器件)发光亮度较低和功耗较大的一大制约因素。
L CF＝τ×α×L    公式(1)；
在公式(1)中，τ表示OLED显示器件中CF的透过率，α表示OLED显示器件中AA区的开口率，L表示OLED显示器件发出白光的亮度，L CF表示OLED显示器件发出的白光透过CF后人眼可以感受到的亮度。
另一方面，一些OLED显示器件(例如，Micro OLED显示器件)中的像素排布会采用如图2A所示的由RGB(Red、Green、Blue，红、绿、蓝)三色子像素组成一个像素的像素结构设计，其中，根据是否采用子像素渲染，又可分为BV3排布和Delta RGB排布这两种像素排布。但是，这两种像素排布会使得大部分OLED显示器件存在功耗偏大和发光亮度偏低的问题，并且，如图2B所示，当视角较大时，会出现串色问题。
又一方面，一些OLED显示器件(例如，Micro OLED显示器件)中因BM的材料问题，一直未导入BM防止RGB间的串色问题，仅通过CF(例如，RGB彩胶)之间的叠加(Overlay)起到防止大视角串色的作用。但是，当视角较大时，RGB之间的CF Overlay几乎没有防止串色的作用。所以，一些OLED显示器件(例如，Micro OLED显示器件)会存在大视角串色严重的问题。而且，引入BM或CF Overlay会导致开口率减小，从而加剧了一些OLED显示器件的发光亮度较低的问题。
本公开实施例提供一种像素结构，该像素结构可以包括：多个像素行和多个像素列，每一个像素行可以包括：四种不同颜色的子像素，多个像素列可以包括：交替排布的多个第一像素列和多个第二像素列，每一个第一像素列可以包括：四种不同颜色中的三种颜色的子像素，每一个第二像素列可以包括：四种不同颜色中的三种颜色以外的另外一种颜色的子像素。如此，本公开实施例所提供的像素结构，通过在两列由三种颜色的子像素排布构成的第一像素列之间，引入了一列仅由除该三种颜色以外的另外一种颜色的子像素排布构成的第二像素列，可以在两列第一像素列之间，引入了除三种颜色以外的另外一种颜色的子像素，使得除三种颜色以外的另外一种颜色的子像素可以将该三种颜色的子像素隔开，这样，可以实现四种不同颜色均匀混合，可以提升混色效果，可以提高发光亮度。而且，当第一方向(即像素行的方向)视角产生偏移时，由于三种颜色的子像素的两侧均为除三种颜色以外的另外一种颜色的子像素，那么，三种颜色的子像素中发出的大角度光只会进 入该除三种颜色以外的另外一种颜色的子像素，而不会串到三种颜色的子像素中，可以避免出现严重串色问题，从而，可以避免设置BM或CF Overlay，避免减小开口率，可以提升器件的发光亮度，可以提高器件的透过率和光效。进而，可以提升显示画面的品质。
本公开实施例还提供一种像素结构，该像素结构可以包括：阵列排布的多个像素，每一个像素可以包括：四种不同颜色的子像素；每一个像素中，四种不同颜色的子像素的个数占比可以为1:1:1:3。如此，本公开实施例所提供的像素结构，将四种不同颜色的子像素划分为一个像素，可以提高每一个像素的亮度，可以实现四种不同颜色均匀混合，可以提升混色效果，可以提高发光亮度，可以提升显示画面的品质。这里，当像素结构的子像素的总个数不是6的整数倍时，本公开实施例中所描述的“每一个像素中四种不同颜色的子像素的个数占比可以为1:1:1:3”，可以是指每一个像素中四种不同颜色的子像素的个数占比近似为1:1:1:3。例如，当显示器件中AA区的周边存在虚拟像素(Dummy Pixel)时，此时，会出现个别像素无法满足四种不同颜色的子像素的个数占比为1:1:1:3的情况。
本公开实施例又提供一种像素结构，该像素结构可以包括：阵列排布的多个重复单元，每一个重复单元可以包括：并排设置的三个像素，每一个像素可以包括：四种不同颜色的子像素，三个像素中四种不同颜色的子像素的排布位置不相同。如此，本公开实施例所提供的像素结构，将四种不同颜色的子像素划分为一个像素，并将四种不同颜色的子像素排布不相同的三个像素划分为一个重复单元，可以提高每一个像素的亮度，可以实现四种不同颜色均匀混合，可以提升混色效果，可以提高发光亮度，可保证显示的均一性，可以提升显示画面的品质。
在一种示例性实施例中，四种不同颜色的子像素可以包括：红色(R)子像素、蓝色(B)子像素、绿色(G)子像素和白色(W)子像素，或者，四种不同颜色的子像素可以包括：红色(R)子像素、蓝色(B)子像素、绿色(G)子像素和黄色(Y)子像素，或者，四种不同颜色的子像素可以采用其它颜色搭配，这里，本公开实施例对此不做限定。
在一种示例性实施例中，四种不同颜色中的三种颜色以外的另外一种颜 色的子像素可以包括：白色(W)子像素、黄色(Y)子像素或者其它颜色的子像素，这里，本公开实施例对此不做限定。
在一种示例性实施例中，以四种不同颜色的子像素可以包括：红色(R)子像素、蓝色(B)子像素、绿色(G)子像素和白色(W)子像素为例，四种不同颜色中的三种颜色的子像素可以包括：红色(R)子像素、蓝色(B)子像素和绿色(G)子像素，四种不同颜色中的三种颜色以外的另外一种颜色的子像素可以为白色(W)子像素。
图3为本公开示例性实施例中的像素结构的一种结构示意图，图4为本公开示例性实施例中的像素结构的另一种结构示意图。其中，在图3和图4中，以四种不同颜色中的三种颜色的子像素包括：红色(R)子像素、蓝色(B)子像素和绿色(G)子像素，四种不同颜色中的三种颜色以外的另外一种颜色的子像素为白色(W)子像素为例，示出了像素结构中的9个像素行33以及交替排布的6个第一像素列31和6个第二像素列32，并且示出了像素结构中的6个重复单元30，每一个重复单元30包括3个像素34，每一个像素34包括3个白色(W)子像素、1个红色(R)子像素、1个蓝色(B)子像素和1个绿色(G)子像素。这里，本公开实施例所提供的像素结构包括但不限于上述方式，例如，图3和图4所示的重复单元中的红色(R)子像素、蓝色(B)子像素和绿色(G)子像素的位置可以互换。例如，图3和图4所示的像素结构中的四种不同颜色的子像素的位置可以互换。例如，图3和图4所示的像素结构中的四种不同颜色的子像素的颜色可以互换。本公开示例性实施例对此不做限定。
下面结合图3和图4，对本公开实施例中的像素结构进行说明。
在一种示例性实施例中，如图3和图4所示，第一像素列31可以由红色(R)子像素、蓝色(B)子像素和绿色(G)子像素排布构成，第二像素列32可以仅由白色(W)子像素排布构成。这样，在像素结构中，沿第一方向(即行方向)，白色(W)子像素可以将红色(R)子像素、蓝色(B)子像素和绿色(G)子像素中任意两种不同颜色的子像素隔开(例如，在像素行33中，白色(W)子像素可以将红色(R)子像素与绿色(G)子像素分开，将绿色(G)子像与蓝色(B)子像素分开，并将蓝色(B)子像素与红色(R) 子像素分开)。如此，当在第一方向上视角产生偏移时，如图5所示，可以使得从红色(R)子像素、蓝色(B)子像素和绿色(G)子像素中任意一种发出的大角度光，只会进入到相邻的白色(W)子像素中，而不会串到其它子像素中，从而，可以避免出现串色问题。并且，可以提升混色效果，可以提高发光亮度，可以提升显示画面的品质。
在一种示例性实施例中，如图3和图4所示，每一个像素行33可以呈直线状。
在一种示例性实施例中，每一个像素行可以呈折线状。例如，如图3和图4所示，交替排布的第一像素列31和第二像素列32均呈折线状。
在一种示例性实施例中，每一个第一像素列中的三种颜色子像素的个数相等。例如，如图3和图4所示，第一像素列31中的红色(R)子像素、蓝色(B)子像素和绿色(G)子像素的个数相等。
在一种示例性实施例中，如图3和图4所示，第二像素列32的子像素的总个数和第一像素列31的子像素的总个数相等。
在一种示例性实施例中，每一个像素行中的四种不同颜色的子像素的个数占比可以为1：1：1：3。例如，如图3和图4所示，像素行33中红色(R)子像素、蓝色(B)子像素、绿色(G)子像素和白色(W)子像素的个数占比为1：1：1：3。这里，当像素结构的子像素的总个数不是6的整数倍时，本公开实施例中所描述的“每一个像素行中的四种不同颜色的子像素的个数占比为1：1：1：3”，可以是指每一个像素行中的四种不同颜色的子像素的个数占比近似为1：1：1：3。例如，当显示器件中AA区的周边存在虚拟像素(Dummy Pixel)时，此时，会出现像素行中四种不同颜色的子像素的个数占比可能不能满足该比例(即1:1:1:3)的情况。
在一种示例性实施例中，每一个像素行中的相邻的子像素的颜色不相同。例如，如图3和图4所示，白色(W)子像素可以将红色(R)子像素、蓝色(B)子像素和绿色(G)子像素中的任意两种不同颜色的子像素隔开，可以避免红色(R)子像素、蓝色(B)子像素和绿色(G)子像素中任意两种相邻。这样，当在第一方向(像素行的方向)上视角产生偏移时，如图5所示，由于红色(R)子像素、蓝色(B)子像素和绿色(G)子像素中任意一 种子像素的相邻子像素均为白色(W)子像素，可以使得从红色(R)子像素、蓝色(B)子像素和绿色(G)子像素中发出的大角度光，只会进入到相邻的白色(W)子像素中，而不会串到其它颜色的子像素中。如此，可以避免出现严重串色问题，可以提高混色效果，可以提高发光亮度，可以提升显示画面的品质。
在一种示例性实施例中，如图3和图4所示，第一像素列31可以包括以下排布中的一种或者多种：依次交替排布的红色(R)子像素、蓝色(B)子像素和绿色(G)子像素，依次交替排布的绿色(G)子像素、红色(R)子像素和蓝色(B)子像素，以及依次交替排布的蓝色(B)子像素、绿色(G)子像素和红色(R)子像素。例如，如图3和图4所示，像素结构包括：依次交替排布的上述三种排布方式的第一像素列31，这样，使得红色(R)子像素、蓝色(B)子像素和绿色(G)子像素在一个重复单元30中可以均匀排布，可以提升器件的发光亮度，可以提高器件的透过率和光效，可以提高混色效果，可以提升显示画面的品质。
在一种示例性实施例中，如图3和图4所示，每一个第一像素列31中的相邻的子像素的颜色不相同。
在一种示例性实施例中，像素结构中的多个像素列中的相邻的第一像素列中相邻的子像素的颜色不相同。例如，如图3和图4所示，第一个第一像素列31包括：依次交替排布的红色(R)子像素、蓝色(B)子像素和绿色(G)子像素，第二个第一像素列31包括：依次交替排布的绿色(G)子像素、红色(R)子像素和蓝色(B)子像素，如此，沿第一方向，第一个第一像素列31中的红色(R)子像素与第二个第一像素列31中的绿色(G)子像素相邻，第一个第一像素列31中的蓝色(B)子像素与第二个第一像素列31中的红色(R)子像素相邻，第一个第一像素列31中的绿色(G)子像素与第二个第一像素列31中的蓝色(B)子像素相邻。
在一种示例性实施例中，每一个子像素的形状可以为六边形，且六边形的六个内角均为120°。如此，可以使得像素结构中的多个子像素之间紧密排列，可以提升开口率，可以提高发光亮度，可以降低功耗。
在一种示例性实施例中，以每一个子像素的形状为六边形为例，六边形 的三组对边平行，且至少两组对边的长度相等。如此，可以使得像素结构中的多个子像素之间紧密排列，可以提升开口率，可以提高发光亮度，可以降低功耗。
例如，如图3所示，每一个子像素的形状可以为正六边形，正六边形的三组对边均平行，且六个边的长度均相等。又例如，如图4所示，每一个子像素的形状可以为平行六边形，平行六边形的三组对边均平行，且两组对边的长度相等。例如，如图6所示，该平行六边形可以包括：第一边(ab边)、第二边(bc边)、第三边(cd边)、第四边(de边)、第五边(ef边)和第六边(fa边)，其中，第一组对边包括：相互平行的第一边(ab边)和第四边(de边)，第二组对边包括：相互平行的第二边(bc边)和第五边(ef边)，第三组对边包括：相互平行的第三边(cd边)和第六边(fa边)，第一组对边和第三组对边的长度可以相等。其中，图6中以一个子像素为例进行示意。
在一种示例性实施例中，以6个子像素划分为一个像素，并排设置的三个像素划分为一个重复单元为例，如图3和图4所示，该像素结构可以包括：沿第一方向(行方向)和第二方向(列方向)阵列排布的多个重复单元30，每个重复单元30的每一行包括：1个红色(R)子像素、1个蓝色(B)子像素、1个绿色(G)子像素和3个白色(W)子像素，每一个重复单元30可以包括：并排设置的三个像素34，每一个重复单元30中三个像素34的子像素排布不同。每一个像素34可以包括：1个红色(R)子像素、1个蓝色(B)子像素、1个绿色(G)子像素和3个白色(W)子像素，每一个像素34的第一列包括：呈折线状排布的1个红色(R)子像素、1个蓝色(B)子像素和1个绿色(G)子像素，每一个像素34的第二列包括：呈折线状排布的3个白色(W)子像素，每一个子像素的形状为六边形，且六边形的六个内角均为120°。
如此，一方面，将1个红色(R)子像素、1个蓝色(B)子像素、1个绿色(G)子像素和3个白色(W)子像素划分为一个像素，可以提高每一个像素的亮度，可以实现多个颜色的子像素颜色均匀混合，提升显示画面的品质；另一方面，每个重复单元30的每一行包括：1个红色(R)子像素、1 个蓝色(B)子像素、1个绿色(G)子像素和3个白色(W)子像素，每一个重复单元30中三个像素34的子像素排布不同，并且每一个像素34可以包括：1个红色(R)子像素、1个蓝色(B)子像素、1个绿色(G)子像素和3个白色(W)子像素，每一个像素34的第一列包括：呈折线状排布的1个红色(R)子像素、1个蓝色(B)子像素和1个绿色(G)子像素，每一个像素34的第二列包括：呈折线状排布的3个白色(W)子像素，可以提高每一个重复单元的亮度，可以实现多个颜色的子像素颜色均匀混合，提升显示画面的品质；又一方面，由于每一个子像素的形状为六边形，且六边形的六个内角均为120°，可以使得像素结构中的多个子像素之间紧密排列，可以提升开口率，使得发光亮度更高，降低功耗。那么，将本公开示例性实施例中所提供的像素结构应用到显示产品中，可以提高显示产品的发光亮度，可以降低显示产品的功耗。从而，可以实现更大的动态显示范围。进而，可以应用于平视显示器(Head Up Display，HUD)领域、透明显示领域、增强现实(Augmented Reality，AR)显示领域或者虚拟现实(Virtual Reality，VR)显示领域等。其中，相较于图2A所示的像素结构，本公开示例性实施例中所提供的像素结构的发光亮度可以约提升1.5倍至2倍。
在一种示例性实施例中，如图3和图4所示，每一个重复单元30可以包括：沿第一方向依次排列的第一像素、第二像素和第三像素，第一像素的第一行可以包括：沿第一方向依次排列的红色(R)子像素和白色(W)子像素，第一像素的第二行可以包括：沿第一方向依次排列的蓝色(B)子像素和白色(W)子像素，第一像素的第三行可以包括：沿第一方向依次排列的绿色(G)子像素和白色(W)子像素；第二像素的第一行可以包括：沿第一方向依次排列的绿色(G)子像素和白色(W)子像素，第二像素的第二行可以包括：沿第一方向依次排列的红色(R)子像素和白色(W)子像素，第二像素的第三行可以包括：沿第一方向依次排列的蓝色(B)子像素和白色(W)子像素；第三像素的第一行可以包括：沿第一方向依次排列的蓝色(B)子像素和白色(W)子像素，第三像素的第二行可以包括：沿第一方向依次排列的绿色(G)子像素和白色(W)子像素，第三像素的第三行可以包括：沿第一方向依次排列的红色(R)子像素和白色(W)子像素。如此，在重复单元的每一行上均有相同数量的红色(R)子像素、蓝色(B)子 像素和绿色(G)子像素，并且每一个红色(R)子像素、每一个蓝色(B)子像素和每一个绿色(G)子像素均可以与白色(W)子像素相邻，因此，可以提升器件的发光亮度，可以提高器件的透过率和光效，能够保证混色非常均匀，可以提升显示画面的品质，并且可以使得从红色(R)子像素、蓝色(B)子像素和绿色(G)子像素中任意一种发出的大角度光，只会进入到相邻的白色(W)子像素中，而不会串到其它子像素中，可以避免出现串色的问题，使得混色效果更佳，显示画面的品质更佳，发光亮度更高。
在一种示例性实施例中，图3和图4所示的像素结构中的第一像素、第二像素和第三像素这三个像素的排序位置可以互换，例如，图3中的每一个重复单元30可以包括：沿第一方向依次排列的第二像素、第一像素和第三像素等，这里，本公开实施例对此不做限定。
在一种示例性实施例中，在每一个重复单元中，相同颜色的多个子像素的尺寸相同。例如，如图3和图4所示，在每一个重复单元30中，三个红色(R)子像素的尺寸相同，或者，三个蓝色(B)子像素的尺寸相同，或者，三个绿色(G)子像素的尺寸相同，或者，九个白色(W)子像素的尺寸相同。如此，可保证显示的均一性。
在一种示例性实施例中，在每一个重复单元中，所有子像素的形状、尺寸和摆放角度均相同。例如，如图3和图4所示，在每一个重复单元30中，18个子像素的形状、尺寸和摆放角度均相同。如此，可保证显示的均一性。
在一种示例性实施例中，由于不同颜色的子像素的发光效率和寿命不相同，因此，在一个重复单元中，可以根据不同颜色的子像素的发光效率和寿命，来设置不同颜色的子像素所对应的面积，以提升产品亮度和寿命。
例如，可以根据亮度提升比例设计要求和寿命(Lifetime)设计要求对红色(R)子像素、蓝色(B)子像素、绿色(G)子像素和白色(W)子像素这四种子像素在一个重复单元中的面积占比进行灵活调整。
例如，由于蓝色(B)子像素在同等电流强度下的发光效率低于绿色(G)子像素在同等电流强度下的发光效率和红色(R)子像素在同等电流强度下的发光效率，而且在一个重复单元中红色(R)子像素、绿色(G)子像素和蓝色(B)子像素的个数占比为1:1:1，因此，可以增加蓝色(B)子像素的 面积，即可以设置蓝色(B)子像素大于红色(R)子像素的面积，并大于绿色(G)子像素的面积。如此，可以提高像素结构的亮度和使用寿命。
例如，RBG三色子像素在白光下对亮度贡献值分别为：红色(R)子像素约占20％至25％，绿色(G)子像素约占50％至60％，蓝色(B)子像素约占20％至25％。RGB三色的有机材料的寿命为：红色(R)子像素的寿命约为17000小时至18000小时，绿色(G)子像素的寿命约为26000小时至27000小时，蓝色(B)子像素的寿命约为6000小时至7000小时，因此，可以设置红色(R)子像素、绿色(G)子像素和蓝色(B)子像素在一个重复单元中的面积占比约为1:1:2。
在一种示例性实施例中，以每一个子像素的形状为三组对边平行，且至少两组对边的长度相等，且六个内角均为120°的六边形为例，每一个重复单元的长度为每一个重复单元的宽度的3倍。例如，如图7所示，每一个重复单元的长度可以是指在第一方向上的等效长度(Pitch_H)，每一个重复单元的宽度可以是指重复单元在第二方向上的等效长度(Pitch_V)。这里，图7中以一个重复单元为例进行示意。
在一种示例性实施例中，如图7和图8所示，任意相邻的两个子像素之间的最小距离Space可以相等。这里，相邻两个子像素之间的最小距离Space可以表示BM或者CF Overlay的宽度。
在一种示例性实施例中，如图8所示，任意相邻的两个子像素之间的最小距离Space可以等于0，即Space＝0，表示无BM或CF Overlay。或者，如图7所示，任意相邻的两个子像素之间的最小距离可以大于0，即Space＝Xμm(微米)，(X≠0，且X>0)，表示BM或CF Overlay的宽度为Xμm。例如，如图9所示，任意相邻的两个子像素之间的最小距离Space可以完全一致，即任意两个六边形子像素的六边之间的间距均可以为Xμm。例如，同一个重复单元内的任意相邻的两个子像素之间的最小距离Space可以约为0.6μm。
在一种示例性实施例中，如图8所示，以在每一个重复单元中，所有子像素的形状、尺寸和摆放角度均可以相同，任意相邻的两个子像素之间的最小距离Space等于0为例，并以子像素的形状为平行六边形为例，如图6所 示，子像素的宽度R1可以是指子像素的第二边(bc边)和第五边(ef边)在第一方向上的最小距离，子像素的等效长度R2可以是指子像素的顶点d与顶点f在第二方向上的最小距离，子像素的长度R3可以是指子像素的顶点d与顶点a在第二方向上的最小距离，从而，重复单元的长度和重复单元的宽度可以如公式(2)和公式(3)所示：重复单元的长度Pitch_H可以为子像素的宽度R1的6倍，重复单元的宽度Pitch_V可以为子像素的等效长度R2的2倍与子像素的长度R3之和。
Pitch_H＝6×R1   公式(2)；
Pitch_V＝2×R2+R3   公式(3)；
其中，Pitch_H表示重复单元的长度，Pitch_V表示重复单元的宽度，R1表示子像素的宽度，R2表示子像素的等效长度，R3表示子像素的长度。
在一种示例性实施例中，如图7所示，以在每一个重复单元中，所有子像素的形状、尺寸和摆放角度均可以相同，且任意相邻的两个子像素之间的最小距离Space大于0为例，并以子像素的形状为平行六边形为例，如图6所示，子像素的宽度R1可以是指子像素的第二边(bc边)和第五边(ef边)在第一方向上的最小距离，子像素的等效长度R2可以是指子像素的顶点d与顶点f在第二方向上的最小距离，子像素的长度R3可以是指子像素的顶点d与顶点a在第二方向上的最小距离，从而，重复单元的长度和重复单元的宽度可以如公式(4)和公式(5)所示。
Pitch_H＝3×W R1+R R1+G R1+B R1+6×Space  公式(4)；
Pitch_V＝R R3+G R2+B R3+Space×sqrt(3)  公式(5)；
其中，Pitch_H表示重复单元的长度(即重复单元在第一方向上的等效距离)，W R1表示白色(W)子像素的宽度，R R1表示红色(R)子像素的宽度，G R1表示绿色(G)子像素的宽度，B R1表示蓝色(B)子像素的宽度，Space表示任意相邻的两个子像素之间的最小距离，Pitch_V表示重复单元的宽度(即重复单元在第二方向上的等效距离)，R R3表示红色(R)子像素的长度，G R2表示白色(W)子像素的等效长度，B R3表示蓝色(B)子像素的长度，sqrt(3)表示3的平方根。
在一种示例性实施例中，可以设置像素结构满足下述五个条件中的一个或多个：1、Pitch_V＝Pixel_Pitch，Pitch_H＝3×Pixel_Pitch，即每一个重复单元的长度Pitch_H为每一个重复单元的宽度Pitch_V的3倍，其中，Pixel_Pitch表示两个像素的间距；2、在一个重复单元中红色(R)子像素、绿色(G)子像素、蓝色(B)子像素以及白色(W)子像素这四种子像素的尺寸均一致，即一个最小重复单元中18个子像素的尺寸均相同；3、任意相邻的两个子像素之间的最小距离Space＝0，即无BM或CF Overlay；4、满足公式(2)和公式(3)，即重复单元的长度Pitch_H为子像素的宽度R1的6倍，重复单元的宽度Pitch_V可以为子像素的等效长度R2的2倍与子像素的长度R3之和；5、每一个子像素的形状为六边形，且六边形的六个内角均为120°。如此，可以提高开口率。例如，可以设置像素结构同时满足上述五个条件，那么，与同可密排的四边形、三角形和其余六边形的像素排布设计相比较，根据上述五个条件所计算出的子像素的尺寸，可以使得本公开示例性实施例所提供的像素结构具有更大的开口率。从而，使得发光亮度更亮。
在一种示例性实施例中，并排设置的三个像素可以组成一个重复单元，在重复单元的基础上，通过排布重复单元阵列，可以实现不同分辨率的像素结构排布。例如，设置FHD(Full High Definition，全高清)显示，分辨率达到1920×1080，那么，可以在第一方向(即水平方向)上设置1920/3＝640列重复单元，并在在第二方向(即竖直方向)上设置1080行重复单元，即可实现FHD 1920×1080的分辨率。
在一种示例性实施例中，在排布重复单元阵列时，使用的尺寸可以根据显示器件的AA区和分辨率来确定。例如，以本公开实施例中的像素结构应用到0.71英寸(inch)的全高清(FHD)显示器件中为例，由于显示屏的大小为0.71英寸，分辨率为FHD 1920×1080，经计算得到两个像素之间的间距Pixel_Pitch可以为8.1μm，那么，根据公式(2)和公式(3)可计算得到每一个重复单元的长度Pitch_H可以为8.1μm×3＝24.3μm，每一个重复单元的宽度Pitch_V可以为8.1μm，如此，对重复单元进行阵列排布时，可满足每一个重复单元的长度Pitch_H可以为每一个重复单元的宽度Pitch_V的3倍。
在一种示例性实施例中，像素结构还可以包括：多条数据信号线(Source  Line)，其中，每一个第二像素列通过一条数据信号线控制，每一个第一像素列通过两条数据信号线控制。如此，该像素结构可减少一条数据信号线。
在一种示例性实施例中，像素结构还可以包括：多条数据信号线，其中，每一个像素中的四种不同颜色中的三种颜色的子像素通过两条数据信号线控制，每一个像素中的四种不同颜色中的三种颜色以外的另外一种颜色的子像素通过同一条数据信号线控制。如此，该像素结构可减少一条数据信号线。
在一种示例性实施例中，当像素结构处于第一显示模式时，像素结构可以以相邻的两个像素行所组成的像素行组为单位进行显示；或者，当像素结构处于第二显示模式时，像素结构可以以一个第一像素列和一个第二像素列所组成的像素列组为单位进行显示；或者，当像素结构处于第三显示模式时，像素结构可以以每一个像素为单位进行显示。
图10为本公开示例性实施例中的像素结构的一种显示示意图，图11为本公开示例性实施例中的像素结构的另一种显示示意图，图12为本公开示例性实施例中的像素结构的又一种显示示意图。下面结合图10、图11和图12对本公开实施例所提供的像素结构的显示方式进行说明。其中，图10、图11和图12均以图3所示的像素结构为例进行示意。
在一种示例性实施例中，当像素结构处于第一显示模式时，像素结构可以以相邻的两个像素行所组成的像素行组为单位进行显示，其中，每个像素行包括：白色(W)子像素、红色(R)子像素、蓝色(B)子像素和绿色(G)子像素，且白色(W)子像素将红色(R)子像素、蓝色(B)子像素和绿色(G)子像素中的任意两个隔开。例如，通过重复单元阵列实现的RGBW像素排布显示水平黑白线时，可通过如图10所示的四条黑白线的方式实现。由图10可以看出，当显示水平黑白线时，一条黑线或一条白线不是通过如图10所示像素点构成的，而是由两行子像素来实现，这样，在显示黑白线时，会具有更高的分辨率，而且水平线的分辨率可以提高1/3。这里，图10中以显示两条白线和两条黑线为例进行示意。
在一种示例性实施例中，当像素结构处于第二显示模式时，像素结构可以以一个第一像素列和一个第二像素列所组成的像素列组为单位进行显示，其中，每个像素列组中的第一像素列包括：红色(R)子像素、绿色(G)子 像素和蓝色(B)子像素，每个像素列组中的第二像素列仅包括白色(W)子像素。例如，通过重复单元阵列实现的RGBW像素排布显示竖直黑白线时，可通过如图11所示的竖直黑白线显示方式实现。由图11可以看出，一条白线或一条黑线在水平方向包括两个子像素，这两个子像素中可包括一个白色(W)子像素，这样，可以提升发光亮度，并避免串色问题；第一像素列中包括红色(R)子像素、绿色(G)子像素和蓝色(B)子像素三色子像素，可以对应彩色线条的显示。这里，图11中以显示三条白线和三条黑线为例进行示意。例如，如图11所示，每个像素列组中的第一像素列中的红色(R)子像素、绿色(G)子像素和蓝色(B)子像素可以通过两条数据信号线给不同的显示信号，每个像素列组中的第二像素列中的所有白色(W)子像素以通过同一条数据信号线给相同的显示信号，如此，该像素结构可节省一条数据信号线。
在一种示例性实施例中，当像素结构处于第三显示模式时，像素结构可以以每一个像素为单位进行显示，其中，每一个像素可以包括3个白色(W)子像素、1个红色(R)子像素、1个蓝色(B)子像素和1个绿色(G)子像素。例如，如图12所示，通过重复单元阵列实现的RGBW像素排布显示一个像素点(Dot)时，可通过如图12所示的3个像素点的方式实现。这里，图12中以点亮了3个像素点为例进行示意。例如，如图12所示，每一个像素中的所有白色(W)子像素可以通过同一条数据信号线给相同的显示信号，每一个像素中的红色(R)子像素、绿色(G)子像素和蓝色(B)子像素可以通过两条数据信号线给不同的显示信号，如此，该像素结构可节省一条数据信号线。
本公开实施例还提供了一种像素结构的驱动方法，该像素结构可以为上述一个或多个示例性实施例中的像素结构。
图13为本公开示例性实施例中的像素结构的驱动方法的流程示意图，如图13所示，该驱动方法可以包括：
步骤1301：获得每帧中每一个像素对应的原始信号；其中，原始信号包括：四种不同颜色中的三种颜色的子像素对应的原始亮度值；
步骤1302：将每一个像素对应的原始信号转化为每一个像素对应的目标信号；其中，目标信号包括：四种不同颜色的子像素对应的目标亮度值；
步骤1303：输出每一个像素对应的目标信号。
例如，以四种不同颜色中的三种颜色的子像素包括：红色(R)子像素、蓝色(B)子像素和绿色(G)子像素，四种不同颜色中的三种颜色以外的另外一种颜色的子像素为白色(W)子像素为例，一般来说，标准的每帧视频信号或图像信号中，每一个像素对应的原始信号中一般只包含R信号(即每一个像素中的红色(R)子像素的原始亮度值)、G信号(即每一个像素中的绿色(G)子像素的原始亮度值)和B信号(即每一个像素中的蓝色(B)子像素的原始亮度值)，并不包含W信号(即白色(W)子像素的原始亮度值)，那么，在驱动本公开实施例所提供的RGBW像素排布的像素结构来说，在接收到每帧视频或图像中每一个像素对应的原始信号之后，可以将接收到的每帧视频或图像中每一个像素对应的原始信号转换为每一个像素对应的目标信号，再将转换后的每一个像素对应的目标信号输出给像素结构，可以实现正确的图像显示，其中，每一个像素对应的目标信号可以包括R信号(即每一个像素中的红色(R)子像素的总亮度值)、G信号(即每一个像素中的绿色(G)子像素的总亮度值)、B信号(即每一个像素中的蓝色(B)子像素的总亮度值)以及W信号(即每一个像素中的白色(W)子像素的总亮度值)。如此，采用与像素结构的排布方式相匹配的驱动方法，可精确地进行彩色显示。
在一种示例性实施例中，步骤1302可以包括以下步骤1401至步骤1402：
步骤1401：确定每一个像素对应的原始信号的最大值和最小值；
步骤1402：基于每一个像素对应的原始信号的最大值和最小值，确定每一个像素对应的目标信号。
这里，每一个像素对应的原始信号的最大值可以是指每一个像素对应的原始信号中四种不同颜色中的三种颜色的子像素对应的原始亮度值中的最大值。每一个像素对应的原始信号的最小值可以是指每一个像素对应的原始信号中四种不同颜色中的三种颜色的子像素对应的原始亮度值中的最小值。
例如，以每一个像素对应的原始信号中一般只包含R信号(即每一个像素中的红色(R)子像素的原始亮度值)、G信号(即每一个像素中的绿色(G)子像素的原始亮度值)和B信号(即每一个像素中的蓝色(B)子像素的原始亮度值)，并不包含W信号(即白色(W)子像素的原始亮度值)为例，每一个像素对应的原始信号的最大值可以是指每一个像素对应的原始信号中红色(R)子像素的原始亮度值、蓝色(B)子像素的原始亮度值和绿色(G)子像素的原始亮度值中的最大值；每一个像素对应的原始信号的最小值可以是指每一个像素对应的原始信号中红色(R)子像素的原始亮度值、蓝色(B)子像素的原始亮度值和绿色(G)子像素的原始亮度值中的最小值。
在一种示例性实施例中，步骤1402可以包括：按照以下公式，基于每一个像素对应的原始信号的最大值和最小值，确定每一个像素对应的目标信号：
W 1＝min(R 0,G 0,B 0)    公式(6)；
Figure PCTCN2021090111-appb-000001
Figure PCTCN2021090111-appb-000002
其中，R 0为原始信号中红色(R)子像素的总亮度值，B 0为原始信号中蓝色(B)子像素的总亮度值，G 0为原始信号中绿色(G)子像素的总亮度值，min(R 0,G 0,B 0)为原始信号的最小值，max(R 0,G 0,B 0)为原始信号的最大值，W 1为目标信号中白色(W)子像素的总亮度值，gain为增益系数，R 1为目标信号中红色(R)子像素的总亮度值，B 1为目标信号中蓝色(B)子像素的总亮度值，G 1为目标信号中绿色(G)子像素的总亮度值。
在一种示例性实施例中，以像素结构中每一个像素包括：1个红色(R)子像素、1个蓝色(B)子像素和1个绿色(G)子像素和3个白色(W)子像素为例，可以将W 1进行均分得到3个白色(W)子像素分别对应的亮度值，此时，一个像素中的3个白色(W)子像素的亮度值相等。或者，可以考虑像素寿命等因素来针对不同位置的白色(W)子像素分配不同的亮度值。例如，可以给在一个像素中，与蓝色(B)子像素相邻的白色(W)子像素分 配较大的亮度值。例如，与红色(R)子像素相邻的白色(W)子像素、与绿色(G)子像素相邻的白色(W)子像素和与蓝色(B)子像素相邻的白色(W)子像素的亮度值占比可以为1:1:2，即与蓝色(B)子像素相邻的白色(W)子像素的亮度值可以为0.5W 1，与红色(R)子像素相邻的白色(W)子像素的亮度值可以为0.25W 1，与绿色(G)子像素相邻的白色(W)子像素可以为0.25W 1。这里，本公开实施例对此不做限定。
