经本案的发明人研究发现，相关技术中，当COE结构的OLED显示面板处于暗态即屏幕在息屏状态时，外界环境光被OLED显示面板内部结构反射后从彩色滤光膜层射出时，因反射光色相偏差以及屏幕出现明显的色分离现象，导致屏幕无法形成暗态纯黑画面的问题。
有鉴于此，为了解决上述技术问题，本公开实施例提供了一种彩膜排布结构，如图3和图4所示，包括两两互不交叠的第一彩膜51、第二彩膜52和第三彩膜53，第一彩膜51覆盖除第二彩膜52和第三彩膜53之间间隙之外的至少部分相邻第二彩膜52之间的区域。
本公开实施例提供的上述彩膜排布结构，通过设置两两互不交叠的第一彩膜51、第二彩膜52和第三彩膜53，且第一彩膜51覆盖除第二彩膜52和第三彩膜53之间间隙之外的至少部分相邻第二彩膜52之间的区域，这样当该彩膜排布结构作为高分辨率的COE结构的显示面板的彩膜层时，可以实现第一彩膜51与第二彩膜52和第三彩膜53不搭接，并且尽可能的提升第一彩膜51的填充面积，可优化产品暗态色相，使显示面板在息屏状态时，减少绿色反射光，使屏幕更趋近于黑色，从而可以解决现有技术中因反射光色相偏差导致屏幕无法形成暗态纯黑画面的问题。
在具体实施时，在本公开实施例提供的上述彩膜排布结构中，如图3和图4所示，第一彩膜51的形状可以为多边形，多边形的拐角为向远离多边形的中心位置一侧凸起的第一圆弧形，这样第一彩膜51的圆弧形拐角设计，可以减弱尖角处的尺寸突变，减弱外界环境光经显示面板后产生的反射光的衍射效应，从而减弱色分离现象；多边形的至少一条边朝向多边形的中心位置凹陷，可选地，如图3所示，多边形(第一彩膜51)的每一条边均为向多边形中心位置一侧凹陷的第二圆弧形；如图4所示，多边形(第一彩膜51)的其中六条边为向多边形中心位置一侧凹陷的第二圆弧形；这样相比于常规显示面板中的彩膜的各拐角位置处均为尖角形，本公开实施例中的圆弧形拐角设计，可以减弱尖角处的尺寸突变，减弱外界环境光经显示面板后产生的反 射光的衍射效应，从而减弱色分离现象。
在具体实施时，在本公开实施例提供的上述彩膜排布结构中，如图3和图4所示，第二彩膜52的形状包括圆形或椭圆形，第三彩膜53的形状包括圆形或椭圆形；本公开实施例以第二彩膜52的形状为圆形，第三彩膜53的形状为椭圆形为例，圆形或椭圆形的彩膜相较于常规显示面板中的彩膜在拐角位置处具有尖角的设计，本公开实施例中的第二彩膜52和第三彩膜53为圆形或椭圆形设计，可以减弱尖角处的尺寸突变，减弱外界环境光经显示面板后产生的反射光的衍射效应，从而减弱色分离现象；
第二彩膜52和第三彩膜53交替设置在第一彩膜51的各条边的一侧，这样可以使得第一彩膜51、第二彩膜52和第三彩膜53紧密排列，从而可以实现高分辨率的COE结构的显示面板。
在具体实施时，在本公开实施例提供的上述彩膜排布结构中，彩膜排布结构可以包括第一区域(对应显示面板的常规显示区)，如图3所示，图3示意出第一区域的部分彩膜结构，第一区域的各第一彩膜51覆盖除第二彩膜52和第三彩膜53之间间隙之外的区域，这样一方面可以避免目前高分辨率显示面板在制作第一彩膜51时，由于第二彩膜52和第三彩膜53之间间隙的距离无法满足第一彩膜51填充在此间隙处，因此本公开实施例的第一彩膜51不覆盖该间隙，可以避免第一彩膜51与第二彩膜52和第三彩膜53交叠，从而避免在暗态色分离出现反射杂光；另一方面可以提高第一彩膜51的制作面积，使得显示面板在暗态时的色相较优；且第一区域的各第一彩膜51的每一条边均朝向多边形的中心位置凹陷，这样相比于常规显示面板中的彩膜的各拐角位置处均为尖角形，本公开实施例中的圆弧形拐角设计，可以减弱尖角处的尺寸突变，减弱外界环境光经显示面板的常规显示区后产生的反射光的衍射效应，从而减弱常规显示区产生色分离的现象。
在具体实施时，在本公开实施例提供的上述彩膜排布结构中，如图3所示，与第二彩膜52和第三彩膜53对应设置的凹陷(第一彩膜51的各条边)表面为第二圆弧形，第二圆弧形与相邻的第二彩膜52的边缘形状可以相同， 第二圆弧形与相邻的第三彩膜53的边缘形状可以相同，实现第一彩膜51与第二彩膜52和第三彩膜53图形互补。
在具体实施时，在本公开实施例提供的上述彩膜排布结构中，彩膜排布结构还包括第二区域(对应显示面板的透光显示区)，如图4所示，图4示意出第二区域的部分彩膜结构，位于第二区域的第一彩膜51覆盖除第二彩膜52和第三彩膜53之间间隙之外的至少部分相邻第二彩膜52之间的区域；
第二区域包括多个透光孔V，透光孔V位于第一彩膜51未覆盖的相邻第二彩膜52之间间隙的区域；由于显示面板中的像素界定层和黑矩阵层无法透光，因此可以在第一彩膜未覆盖的相邻第二彩膜之间间隙的区域对像素界定层和黑矩阵层做挖孔设计，以实现在该挖孔区域透光。
在具体实施时，在本公开实施例提供的上述彩膜排布结构中，如图4所示，第二区域的第一彩膜51的每一条边均朝向多边形的中心位置凹陷，这样可以减弱外界环境光经显示面板的透光显示区A2后产生的反射光的衍射效应，从而减弱透光显示区A2产生色分离的现象；与透光孔V对应设置的凹陷表面为第三圆弧形，透光孔V的形状可以为异形多边形，且透光孔V与相邻凹陷的图形大致互补,这样采用异形多边形结构的透光孔V设计，可以提高透光孔V的面积，从而提高透光显示区A2的透过率，提高环境光调节传感器的灵敏度。
在具体实施时，在本公开实施例提供的上述彩膜排布结构中，如图3和图4所示，第一彩膜可以为红色彩膜(R)，第二彩膜可以为绿色彩膜(G)，第三彩膜可以为蓝色彩膜(B)。
需要说明的是，第一彩膜、第二彩膜、第三彩膜和透光孔的详细描述可以参见下文一种显示面板中的描述。
基于同一发明构思，本公开实施例还提供了一种显示面板，如图1-图4所示，图1为显示面板的平面示意图，图2为图3和图4中在CC’方向的截面示意图，图3为图1中虚线框BB区域内的平面示意图，图4为图1中A2区域内的平面示意图，该显示面板包括：

黑矩阵层4，位于封装层3背离衬底基板1的一侧，黑矩阵层4具有与第一开口(21、22和23)一一对应设置的多个第二开口(41、42和43)；
彩膜层5，位于黑矩阵层4背离衬底基板1的一侧，彩膜层5具有与第二开口(41、42和43)一一对应设置的第一彩膜51、第二彩膜52和第三彩膜53，第一彩膜51、第二彩膜52和第三彩膜53两两互不交叠；具体地，第一开口21、第二开口41和第一彩膜51三者对应设置，第一开口22、第二开口42和第二彩膜52三者对应设置，第一开口23、第二开口43和第三彩膜53三者对应设置，即第一开口21出射红色光线，第一开口22出射绿色光线，第一开口23出射蓝色光线；
其中，第一彩膜51覆盖除第二彩膜52和第三彩膜53之间间隙之外的至少部分相邻第二彩膜52之间的区域。
本公开实施例提供的上述显示面板，通过设置两两互不交叠的第一彩膜51、第二彩膜52和第三彩膜53，且第一彩膜51覆盖除第二彩膜52和第三彩膜53之间间隙之外的至少部分相邻第二彩膜52之间的区域，这样对于高分辨率的显示面板，可以实现第一彩膜51与第二彩膜52和第三彩膜53不搭接，并且尽可能的提升第一彩膜51的填充面积，可优化产品暗态色相，使显示面板在息屏状态时，减少绿色反射光，使屏幕更趋近于黑色，从而可以解决现有技术中因反射光色相偏差导致屏幕无法形成暗态纯黑画面的问题。
在具体实施时，在本公开实施例提供的上述显示面板中，如图2-图4所 示，第一彩膜51可以为红色彩膜(R)，第二彩膜52可以为绿色彩膜(G)，第三彩膜53可以为蓝色彩膜(B)。
在具体实施时，在本公开实施例提供的显示面板中，如图2所示，还包括多个发光器件，每一发光器件包括层叠设置的阳极(未示出)、发光层6和阴极(未示出)，各阳极在像素界定层2之前制作，像素界定层2的第一开口(21、22和23)露出阳极，并且像素界定层2覆盖阳极的边缘区域；各发光层6设置在对应的第一开口(21、22和23)内，例如第一开口21内设置出射红光的发光层6，第一开口22内设置出射绿光的发光层6，第一开口23内设置出射蓝光的发光层6；阴极可以为整面设置的结构。
在具体实施时，在本公开实施例提供的上述显示面板中，如2所示，还包括位于衬底基板1和像素界定层2之间的薄膜晶体管阵列层(未示出)，薄膜晶体管阵列层具体可以包括有源层、栅极绝缘层、栅极层、源漏极导电层和平坦化层，薄膜晶体管阵列层的漏极与阳极电连接，通过薄膜晶体管驱动发光器件发光。
需要说明的是，本公开实施例中的发光器件可以包括：OLED器件或量子点发光二极管(Quantum Dot Light Emitting Diodes，QLED)器件等，对此不作具体限定。
在具体实施时，在本公开实施例提供的上述显示面板中，如2所示，还包括位于彩膜层5背离衬底基板1一侧的保护层7，该保护层7具体可以为光学胶层，以对彩膜层5以及黑矩阵层4进行保护。
在具体实施时，在本公开实施例提供的上述显示面板中，如2所示，在保护层7背离彩膜层5的一侧还设置有盖板(图中未示出)或覆盖膜层(图中未示出)。盖板具体可以为玻璃盖板。
可以理解的是，如图2所示，本公开实施例中的显示面板可以不包括圆偏光片，通过使用本公开实施方式中提供的黑矩阵层4和彩膜层5，在需要进行显示的位置，也即各发光层6所在的位置，发光层6出射的光经过第二开口(41、42和43)进行出射，不影响显示；而对于发光层6以外的位置，可 以由黑矩阵层4进行遮挡，外界环境光无法进入，进而可以起到圆偏光片防止外界光反射的作用。
在具体实施时，如图2所示，第一彩膜51、第二彩膜52和第三彩膜53不仅能够对出射的光线进行过滤处理，提高出射光线的色纯度，还能够对外界光线起到过滤作用，可以减少进入显示面板内的环境光，进而减少显示面板对环境光的反射，提高用户体验。
在具体实施时，COE结构的显示面板在暗态时一般绿色反射光最强、红色反射光最弱，导致暗态时屏幕无法形成纯黑画面，因此在本公开实施例提供的上述显示面板中，如图3和图4所示，第一彩膜51的面积大于第三彩膜53的面积，第三彩膜53的面积大于第二彩膜52的面积。这样在显示面板处于息屏状态时，可以减少绿色反射光，使屏幕更趋近于纯黑画面。
在具体实施时，在本公开实施例提供的上述显示面板中，如图3和图4所示，第一彩膜51外围具有围绕第一彩膜51且交替设置的第二彩膜52和第三彩膜53。具体地，第一彩膜51的形状可以为多边形，围绕第一彩膜51且交替设置的第二彩膜52和第三彩膜53分别位于多边形的各条边的一侧，这样可以使得第一彩膜51、第二彩膜52和第三彩膜53紧密排列，从而可以实现高分辨率的显示面板。
具体地，本公开实施例是以第一彩膜51的主体形状近似为八边形为例，当然不限于此。
在具体实施时，在本公开实施例提供的上述显示面板中，第二彩膜的形状可以包括圆形或椭圆形，第三彩膜的形状可以包括圆形或椭圆形。可选地，如图3和图4所示，本公开实施例以第二彩膜的形状为圆形，第三彩膜的形状为椭圆形为例，圆形或椭圆形的彩膜相较于常规显示面板中的彩膜在拐角位置处具有尖角的设计，本公开实施例中的第二彩膜和第三彩膜为圆形或椭圆形设计，可以减弱尖角处的尺寸突变，减弱外界环境光经显示面板后产生的反射光的衍射效应，从而减弱色分离现象。
需要说明的是，本公开实施例中公开的第二彩膜和第三彩膜的形状为圆 形或椭圆形，是指近似为圆形或椭圆形，可以理解的是，由于制作工艺等原因，制作得到的第二彩膜和第三彩膜的形状不一定为标准的圆形或椭圆形，可以存在一定的误差。
在具体实施时，在本公开实施例提供的上述显示面板中，如图3和图4所示，多边形(第一彩膜51)的拐角为向远离多边形的中心位置一侧凸起的第一圆弧形，这样第一彩膜51的圆弧形拐角设计，相比于常规显示面板中的彩膜的各拐角位置处均为尖角形，本公开实施例中的圆弧形拐角设计，可以减弱尖角处的尺寸突变，减弱外界环境光经显示面板后产生的反射光的衍射效应，从而减弱色分离现象。
在具体实施时，在本公开实施例提供的上述显示面板中，如图5和图6所示，图5为图3中的局部放大示意图，图6为图4中的局部放大示意图，第一圆弧形的半径R1可以在3.5μm～4μm部之间，这样可以保证CD工艺将第一彩膜51的图形稳定的曝光出来，提高工艺稳定性以减小片间差异。
在具体实施时，在本公开实施例提供的上述显示面板中，如图3-图6所示，多边形(第一彩膜51)的至少一条边朝向多边形的中心位置凹陷。可选地，如图3和图5所示，多边形(第一彩膜51)的每一条边均朝向多边形的中心位置凹陷；如图4和图6所示，多边形(第一彩膜51)的其中六条边朝向多边形的中心位置凹陷；这样相比于常规显示面板中的彩膜的各条边均为直线，本公开实施例中的各条边凹陷设计，可以减弱外界环境光经显示面板后产生的反射光的衍射效应，从而减弱色分离现象。
在具体实施时，在本公开实施例提供的上述显示面板中，如图3-图6所示，与第二彩膜52和第三彩膜53对应设置的凹陷表面可以为第二圆弧形，第二圆弧形与相邻的第二彩膜52的边缘形状可以相同，第二圆弧形与相邻的第三彩膜53的边缘形状可以相同，实现第一彩膜51与第二彩膜52和第三彩膜53图形互补。
在具体实施时，在本公开实施例提供的上述显示面板中，如图5和图6所示，相邻第一彩膜51和第二彩膜52之间的间隙宽度d1在1μm～1.5μm之 间，相邻第一彩膜51和第三彩膜53之间的间隙宽度d2在1μm～1.5μm之间，相邻第二彩膜52和第三彩膜53之间的间隙宽度d3大于或等于1μm。这样一方面可以防止第一彩膜51、第二彩膜52和第三彩膜53两两之间发生交叠，另一方面可以提高第一彩膜51的填充面积，使得显示面板在暗态时的色相较优。
在具体实施时，在本公开实施例提供的上述显示面板中，如图1和图3所示，显示面板具有常规显示区A1，位于常规显示区A1的第一彩膜51覆盖除第二彩膜52和第三彩膜53之间间隙之外的区域。这样一方面可以避免目前高分辨率显示面板在制作第一彩膜51时，由于第二彩膜52和第三彩膜53之间间隙的距离无法满足第一彩膜51填充在此间隙处，因此本公开实施例的第一彩膜51不覆盖该间隙，可以避免第一彩膜51与第二彩膜52和第三彩膜53交叠，从而避免在暗态色分离出现反射杂光；另一方面可以提高第一彩膜51的制作面积，使得显示面板在暗态时的色相较优。
在具体实施时，在本公开实施例提供的上述显示面板中，如图1和图3所示，位于常规显示区A1的第一彩膜51的每一条边均朝向多边形(第一彩膜51)的中心位置凹陷。这样相比于常规显示面板中的彩膜的各条边位置为直线，本公开实施例中的各条边圆弧形设计，可以减弱外界环境光经显示面板的常规显示区A1后产生的反射光的衍射效应，从而减弱常规显示区A1产生色分离的现象。
在具体实施时，在本公开实施例提供的上述显示面板中，如图1和图3所示，位于常规显示区A1的第一彩膜51可以为中心对称图形。当然，不限于此，只要满足第一彩膜51的各拐角以及各条边均为圆弧形即可。
在具体实施时，为了调节显示面板的环境光亮度，在本公开实施例提供的上述显示面板中，如图1和图4所示，显示面板还具有透光显示区A2，透光显示区A2靠近显示面板的边缘；位于透光显示区A2的第一彩膜51覆盖除第二彩膜52和第三彩膜53之间间隙之外的至少部分相邻第二彩膜52之间的区域；
如图4所示，透光显示区A2包括多个透光孔V，透光孔V位于第一彩膜51未覆盖的相邻第二彩膜52之间间隙的区域；由于像素界定层2和黑矩阵层4无法透光，因此可以在第一彩膜51未覆盖的相邻第二彩膜52之间间隙的区域对像素界定层2和黑矩阵层4做挖孔设计，以实现在该挖孔区域透光。
可选地，透光显示区A2可以位于常规显示区A1内部，例如透光显示区A2可以位于显示面板的左上角或右上角，本公开实施例以透光显示区A2位于显示面板的左上角为例，透光显示区A2的开孔大小可以为数毫米不等。
具体地，在显示面板的透光显示区A2的背面一般设置环境光调节传感器，以调节显示面板的环境光亮度，提高显示效果。
在具体实施时，在本公开实施例提供的上述显示面板中，如图4所示，位于透光显示区A2的第一彩膜51仅有六条边朝向多边形的中心位置凹陷。为了进一步减弱色分离现象，在具体实施时，在本公开实施例提供的上述显示面板中，如图7所示，图7为图1中透光显示区A2的局部放大示意图，位于透光显示区A2的第一彩膜51的每一条边均朝向多边形的中心位置凹陷。这样可以减弱外界环境光经显示面板的透光显示区A2后产生的反射光的衍射效应，从而减弱透光显示区A2产生色分离的现象。
在具体实施时，在本公开实施例提供的上述显示面板中，如图7所示，与透光孔V对应设置的凹陷(第一彩膜51的边)表面为第三圆弧形，透光孔V的形状可以为异形多边形，且透光孔V与相邻凹陷的图形大致互补。这样采用异形多边形结构的透光孔V设计，可以提高透光孔V的面积，从而提高透光显示区A2的透过率，提高环境光调节传感器的灵敏度。
可选地，透光孔V的形状可以为异形五边形、异形七边形、异形十边形等，在此不做限定。本公开实施例是以透光显示区A2内包括不同形状的透光孔V为例，当然，各透光孔V的形状也可以相同，根据实际情况进行制作，并且尽可能的使透光孔V的面积最大化，以提高透光显示区A2的透过率。
具体地，图4仅示意出在透光显示区A2内4*4像素循环单元下的像素界 定层、黑矩阵层及彩膜层设计Layout(版图)示意图，与常规显示区A1不同的是，在透光显示区A2，需要进行像素界定层2和黑矩阵层4的挖孔设计，以保证环境光(例如550nm)的透过率，确保环境光调节传感器的识别性能。透光孔V位于相邻第二彩膜52之间，在显示面板的厚度方向上，透光孔V为贯穿像素界定层和黑矩阵层的套孔结构，这样每个像素单元(包括红色子像素R、绿色子像素G、蓝色子像素B)可以有一个透光孔V，同时为保证开口率最大化，可以压缩子像素的像素电路面积，并将透光孔V进行异形多边形设计。
在具体实施时，在本公开实施例提供的上述显示面板中，如1、图7-图9所示，图8和图9分别为图1中透光显示区A2内的另外两种局部放大示意图；
如图7所示，在透光显示区A2，第一彩膜51包括沿第一方向Y延伸的长轴和沿第二方向X延伸的短轴，透光孔V位于短轴的两端；其中，第一方向Y和第二方向Y交叉设置；
或，如图8所示，在透光显示区A2，第一彩膜51包括沿第一方向Y延伸的短轴和沿第二方向X延伸的长轴，透光孔V位于短轴的两端；
或，如图9所示，在透光显示区A2，一部分第一彩膜51包括沿第一方向Y延伸的长轴和沿第二方向X延伸的短轴，另一部分第一彩膜51包括沿第一方向Y延伸的短轴和沿第二方向X延伸的长轴，透光孔V位于短轴的两端。这样可以尽可能多的设置透光孔V的数量，进一步提高透光显示区A2的透过率。
在具体实施时，在本公开实施例提供的上述显示面板中，如1、图7-图9所示，该显示面板包括交叉设置的数据线(未示出)和栅线(未示出)，例如栅线沿第二方向X延伸，数据线沿第一方向Y延伸。
在具体实施时，为保证透光孔的透光性，在本公开实施例提供的上述显示面板中，如6所示，透光孔V与第一彩膜51之间的间隙宽度d4大于或等于1μm，透光孔V与第三彩膜53之间的间隙宽度d5大于或等于1μm。这样可以保证彩膜层不覆盖透光孔V。
可选地，d4和d5设计值的差异主要为第一彩膜51和第三彩膜53的CD Bias(关键尺寸偏置)的差异，第一彩膜51的CD Bias是指其目标尺寸与实际尺寸的偏差，第三彩膜53的CD Bias是指其目标尺寸与实际尺寸的偏差，例如d4和d5的目标值可以均为1.5μm，避免第一彩膜51、第三彩膜53覆盖透光孔V。
在具体实施时，在本公开实施例提供的上述显示面板中，如2-图4所示，第二开口(41、42和43)的面积大于第一开口(21、22和23)的面积。这样可以提高出射光的出光效率。
在具体实施时，在本公开实施例提供的上述显示面板中，如2-图4所示，第一彩膜51的面积、第二彩膜52的面积和第三彩膜53的面积分别大于各自对应的第二开口的面积，例如第一彩膜51的面积大于第二开口41的面积，第二彩膜52的面积大于第二开口42的面积，第三彩膜53的面积大于第二开口43的面积，这样可以使得显示面板在暗态时减弱色分离的现象以获得较优的色相。
在具体实施时，在本公开实施例提供的上述显示面板中，如3和图4所示，第一开口(21、22和23)的形状可以包括圆形或椭圆形，第二开口(41、42和43)的形状可以包括圆形或椭圆形。
在具体实施时，在本公开实施例提供的上述显示面板中，如1所示，还包括屏下摄像头区A3，屏下摄像头区A3靠近显示面板的边缘。具体地，屏下摄像头区A3可以位于常规显示区A1内，通过在常规显示区A1挖孔设计形成屏下摄像头区A3，可以实现在屏下摄像头区A3背面设置摄像头等感光器件，可以实现显示面板的窄边框设计。
基于同一发明构思，本公开实施例还提供了一种显示装置，包括本公开实施例提供的上述显示面板。该显示装置解决问题的原理与前述显示面板相似，因此该显示装置的实施可以参见前述显示面板的实施，重复之处在此不再赘述。
在具体实施时，本公开实施例提供的上述显示装置可以为全面屏显示装 置，或者也可以为柔性显示装置等，在此不作限定。
在具体实施时，本公开实施例提供的上述显示装置可以为如图10所示的全面屏的手机。当然，本公开实施例提供的上述显示装置也可以为平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。对于该显示装置的其它必不可少的组成部分均为本领域的普通技术人员应该理解具有的，在此不做赘述，也不应作为对本公开的限制。
