具体实施方式
下面将结合本公开一些实施例中的附图，对本公开一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的一些实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开一些实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。“上/上方”、“下/下方”、等指示的方位或位置关系的术语为基于附图所示的方位或位置关系，仅是为了便于说明本公开一些实施例中技术方案的简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。
在全彩化的OLED显示器中，OLED显示面板内通常呈阵列状设置有多个像素，其中，每个像素包括一红色子像素R、一绿色子像素G、一蓝色子像素B和一白色子像素W。
在一些示例中，每个像素所包括的红色子像素R、绿色子像素G和蓝色子像素B分别由WOLED叠加对应颜色的滤光层构成，白色子像素W由WOLED叠加透明绝缘层构成。各子像素中的WOLED的发光层连接为一整层，可便于制作OLED显示面板。然而，每一白色子像素W与相邻的一彩色子像素(例如红色子像素R)之间通常设置有两条信号线(例如SD线)，尽管每条信号线的线径很小，且所述两条信号线之间的间隔很小，但所述两条信号线之间的间隔处容易因对应的发光层的部分发出的白光而漏光，使得OLED显示面板出现色偏问题，从而影响OLED显示器的显示效果。
基于此，请参阅图1-图4，本公开一些实施例提供了一种显示面板100，该显示面板100具有呈阵列状排布的多个像素区域10a；每个像素区域10a包括多个子像素区域，多个子像素区域中的一个子像素区域为白色子像素区域W(例如图1中所示)，其余子像素区域为彩色子像素区域(例如图1中所示的P 1、P 2、P 3)。该显示面板100包括：位于至少一个白色子像素区域W与相邻的一个彩色子像素区域(例如为P 3)之间的两条信号线20，所述两条信号线20之间具有间隔D；以及，至少一个滤光组3，其中，每个滤光组3包括层叠设置的第一滤光块31和第二滤光块32，且第一滤光块31和第二滤光块32的交叠部分30覆盖一个所述间隔D，第一滤光块31的透光波段与第二滤光块32的透光波段无重叠。
此处，像素区域为由对应像素的边界所界定的空间区域，子像素区域为由对应子像素的边界所界定的空间区域。第一滤光块31的透光波段为第一滤光块31允许透过的光的波长范围，第二滤光块32的透光波段为第二滤光块32允许透过的光的波长范围。此外，第一滤光块31和第二滤光块32二者的透光波段，取决于二者的颜色。例如，第一滤光块31的颜色为蓝色，其透光波段即为蓝光波段；第二滤光块32的颜色为红色，其透光波段即为红光波段。本公开一些实施例对第一滤光块31和第二滤光块32的颜色不作限定，只要满足第一滤光块31的透光波段与第二滤光块32的透光波段无重叠，从而使得白光无法从交叠的第一滤光块31与第二滤光块32透过即可。
请参阅图1和图2，显示面板100还包括：设置有多条信号线20和至少一个滤光组3的基板10。前述每个滤光组3中第一滤光块31和第二滤光块32层叠设置，表现为第二滤光块32设置于基板10表面，第一滤光块31设置于第二滤光块32远离基板10的一侧，如图2所示；或者，第一滤光块31设置于基板10表面，第二滤光块32设置于第一滤光块31远离基板10的一侧，如图4所示。
在一些示例中，如图1所示，每个滤光组3中的第二滤光块32设置于第一滤光块31远离基板10的一侧，在此情况下，显示面板100中，第二滤光块32位于第一滤光块31远离基板10的一侧，即第一滤光块31被第二滤光块32所遮挡住，故上述图1中未示意出第一滤光块31的附图标记“31”。
显示面板100还包括：至少覆盖每个第二滤光块32的透明绝缘层50。此处，透明绝缘层50至少覆盖每个第二滤光块32，是指透明绝缘层50包括覆盖每个第二滤光块32的部分，以及位于每个第二滤光块32外其他区域的部分，该其他区域例如为至少一个白色子像素区域W或与所述至少一个白色子像素区域W相邻的至少一个彩色子像素区域。
请继续参阅图1和图2，显示面板100还包括：位于透明绝缘层50远离基板10的一侧、且位于每个子像素区域内的多个白光有机发光二极管8，其中，每个白光有机发光二极管8的光发射方向朝向基板10(如图2和图4中箭头所指方向)。此处，白光有机发光二极管8通常包括依次远离基板10设置的透明阳极81、发光层82和反射阴极83。
在一些示例中，每相邻两个白光有机发光二极管8的发光层82相连接，也即各白光有机发光二极管8的发光层82制作为一整层，有利于简化显示面板100的制作工艺。
请继续参阅图1和图2，显示面板100还包括与每个白光有机发光二极管8连接的驱动晶体管60，所述驱动晶体管60被配置为驱动对应的白光有机发光二极管8发光。这里，驱动晶体管60包括薄膜晶体管(Thin Film Transistor，简称TFT)，显示面板100为有源矩阵有机发光二极管(Active-matrix organic light emitting diode，简称AMOLED)显示面板。
在一些示例中，每个驱动晶体管60的输出端通常与对应白光有机发光二极管8的阳极连接，各驱动晶体管60设置于透明绝缘层50的靠近基板10的一侧。当然，本公开一些实施例对各驱动晶体管60的设置位 置不作限定，例如，各驱动晶体管60设置于透明绝缘层50的背离基板10的一侧，也是允许的。
此外，显示面板100中的多个像素区域10a呈阵列状设置，与每个像素区域10a对应的像素的显示需要通过至少一条数据线和至少一条栅线进行驱动。例如，每个驱动晶体管60的栅极连接一条栅线，每个驱动晶体管60的源极连接一条数据线。当然，不同驱动晶体管60的栅极连接同一条栅线，或不同驱动晶体管60的栅极连接不同的栅线，均是允许的。同理，不同驱动晶体管60的源极连接同一条数据线，或不同驱动晶体管60的源极连接不同的数据线，也均是允许的。
在一些示例中，请参阅图1，信号线20为数据线，显示面板100还包括多条栅线70。各驱动晶体管60在基板10上的正投影位于其对应连接的栅线70在基板10上的正投影内，有利于提高各子像素区域的开口率，也即各像素的开口率，从而提高显示面板100的出光率。在另一些示例中，请继续参阅图1，信号线20为栅线，显示面板100还包括多条数据线70。可见，前述一些实施例中的信号线20为栅线或数据线，均可。
在每个像素区域10a中，当发光层82发出的白光在照射至所述像素区域10a内每两条信号线20之间的间隔D处时，所述白光先照射至对应的滤光组3中，这样便可以利用该滤光组3中的第一滤光块31和第二滤光块32分别对所述白光进行过滤。由于每个滤光组3中的第一滤光块31的透光波段与第二滤光块32的透光波段无重叠，也即第一滤光块31允许透过的光无法从第二滤光块32透过，或第二滤光块32允许透过的光无法从第一滤光块31透过，因此，利用各滤光组3可以防止前述白光从所述像素区域10a内每两条信号线20之间的间隔D处射出，从而避免所述像素区域10a内每两条信号线20之间的间隔D处漏光，进而避免显示面板100出现色偏问题，有利于提升显示面板100的显示效果。
在一些实施例中，每个像素区域10a中白色子像素区域W以外的其 余子像素区域包括用于显示至少一种颜色的至少一个彩色子像素区域。显示面板100还包括位于每个彩色子像素区域内的彩色滤光膜。在每个滤光组3中，第一滤光块31和第二滤光块32中一者的材料与相邻的彩色滤光膜的材料相同。这样，在制作每个滤光组3的过程中，与相邻的彩色滤光膜的材料相同的第一滤光块31或第二滤光块32可以和该彩色滤光膜通过一次构图工艺形成，以减少制作滤光组3的工序，从而提高显示面板的生产效率。此处，构图工艺是对任意膜层(由一层或多层薄膜)进行处理以形成具有特定图案膜层的工艺。例如，光掩膜(Mask)工艺。
在一些示例中，每个第一滤光块31的材料与相邻的彩色滤光膜的材料相同，且每个第一滤光块31与相邻的彩色滤光膜相连接。示例的，每个彩色滤光膜配置为与相邻第一滤光块31连接的部分覆盖在对应两条信号线20中靠近所述彩色滤光膜的一条信号线20上；或，每个第一滤光块31的配置为与相邻彩色滤光膜连接的部分覆盖在对应两条信号线20中靠近所述彩色滤光膜的一条信号线20上。这样，每个第一滤光块31与相邻的彩色滤光膜不仅可以通过一次构图工艺形成，还可以在对各第一滤光块31和各彩色滤光膜进行构图形成的过程中，减小构图设计的复杂程度，从而简化对应掩膜板的设计制作以及显示面板的制作，有利于提高显示面板的生产效率。
示例性的，如图1所示，每个像素区域10a中白色子像素区域W以外的其余子像素区域包括一个第一颜色子像素区域P 1、一个第二颜色子像素区域P 2和一个第三颜色子像素区域P 3。显示面板还包括：位于每个第一颜色子像素区域P 1内的第一颜色滤光膜41，位于每个第二颜色子像素区域P 2内的第二颜色滤光膜42，位于每个第三颜色子像素区域P 3内的第三颜色滤光膜43；其中，第一颜色滤光膜41、第二颜色滤光膜42和第三颜色滤光膜43的颜色互不相同。
本公开一些实施例对上述的第一颜色滤光膜41、第二颜色滤光膜 42、第三颜色滤光膜43各自的颜色不进行限定，三种颜色的滤光膜的颜色可与三原色红、绿、蓝任意对应，只要三种颜色的滤光膜的颜色互不相同即可。例如：第一颜色滤光膜41、第二颜色滤光膜42和第三颜色滤光膜43的颜色分别为红/绿/蓝、或分别为绿/红/蓝、或分别为蓝/绿/红、或分别为绿/蓝/红、或分别为红/蓝/绿、或分别为蓝/红/绿。
示例的，第一颜色滤光膜41为红色滤光膜，第二颜色滤光膜42为绿色滤光膜，第三颜色滤光膜43为蓝色滤光膜。
在一些实施例中，第一滤光块31的材料与第一颜色滤光膜41、第二颜色滤光膜42、第三颜色滤光膜43三者中的任一者的材料相同；第二滤光块32的材料与第一颜色滤光膜41、第二颜色滤光膜42、第三颜色滤光膜43三者中的任一者材料相同，且第二滤光块32的材料与第一滤光块31的材料不相同。这样，每个第一滤光块31可以和与该第一滤光块31材料相同的滤光膜在同一构图工艺中一道形成，简化了上述显示面板100的制备工艺；同样的，每个第二滤光块32也可以和与该第二滤光块32材料相同的滤光膜在同一构图工艺中一道形成，进一步简化上述显示面板100的制备工艺。
示例性的，与每个白色子像素区域W相邻的一个彩色子像素区域为第三颜色子像素区域P 3，每个第一滤光块31的材料与相邻的第三颜色滤光膜43的材料相同。基于此，每个第一滤光块31与相邻的第三颜色滤光膜43相连接。例如，每个第三颜色滤光膜43的配置为与相邻第一滤光块31连接的部分覆盖在对应两条信号线20中靠近第三颜色子像素区域P 3的一条信号线20上；或，每个第一滤光块31的配置为与相邻第三颜色滤光膜43连接的部分覆盖在对应两条信号线20中靠近第三颜色子像素区域P 3的一条信号线20上。这样，每个第一滤光块31与相邻的第三颜色滤光膜43不仅可以通过一次构图工艺形成，还可以在对各第一滤光块31和各第三颜色滤光膜43进行构图形成的过程中，减小构图设计的复杂程度，从而简化对应掩膜板的设计制作以及显示面板的制作，有 利于提高显示面板的生产效率。
此外，如图2或图4所示，每个第二滤光块32的部分还覆盖在对应两条信号线20中靠近白色子像素区域W的另一条信号线20上，以降低光刻形成各第二滤光块32时所需曝光的精度和难度，例如可以减小曝光时光照度的关键尺寸(Critical Dimension，简称CD)偏差。
在一些示例中，基于第一滤光块31的材料与相邻第三颜色滤光膜43的材料相同，第二滤光块32的材料与第一颜色滤光膜41或第二颜色滤光膜42的材料相同，这样每个第二滤光块32可以和与其颜色相同的第一颜色滤光膜41或第二颜色滤光膜42在同一构图工艺下一次形成，从而进一步简化各滤光组3的制作工艺。
本公开一些实施例对多个像素区域10a，以及每个像素区域10a中各子像素区域的数量和排布方式不作限定。示例的，参考图1和图3所示，沿所述多个像素区域10a排列的行方向或列方向，每个像素区域10a中的多个子像素区域沿按照第一颜色子像素区域P 1、第二颜色子像素区域P 2、白色子像素区域W和第三颜色子像素区域P 3的顺序设置。
基于此，每个像素区域10a中，在第一颜色子像素区域P 1与第二颜色子像素区域P 2之间设有两条信号线20(例如图1和图3所示)，且所述两条信号线20之间也具有间隔的情况下,所述两条信号线20之间的间隔处对应设置如上一些实施例所述的滤光组3，也即，此处滤光组3的结构、设置方式以及其所能实现的技术效果均可参见前述的一些实施例，不再详述。
当然，每个第一颜色子像素区域P 1与相邻第二颜色子像素区域P 2之间两条信号线20的间隔处不设置滤光组3，采用其他的遮光方式，也是允许的。示例的，每个第一颜色子像素区域P 1内的第一颜色滤光膜41覆盖在靠近其的一条信号线20上，并延伸至另一条信号线20；相邻第二颜色子像素区域P 2内的第二颜色滤光膜42覆盖在靠近其的一条信号线20上，并延伸至另一条信号线20。如此，每个像素区域10a内的第 一颜色滤光膜41与第二颜色滤光膜42会在对应的两条信号线20之间产生交叠部分30，以避免所述第一颜色滤光膜41与相邻的第二颜色滤光膜42之间产生混光。此处，第一颜色滤光膜41与第二颜色滤光膜42在两条信号线20之间产生交叠部分30的先后顺序不作限定，图1中仅以第一颜色滤光膜41交叠在第二颜色滤光膜42之上为例进行说明。
此外，上述显示面板100还包括：位于每个第二颜色子像素区域P 2与相邻白色子像素区域W之间的公共电源线21。公共电源线21的线宽通常较信号线20的线宽较宽，且公共电源线21是由不透光的金属材料构成，可以阻挡每个第二颜色子像素区域P 2与相邻白色子像素区域W之间的漏光。示例的，每个第二颜色滤光膜42覆盖在对应公共电源线21的远离基板10的部分表面，以降低光刻形成各第二颜色滤光膜42时所需曝光的精度和难度，有利于简化显示面板100的制作工艺。
请继续参阅图1和图2，在每个像素区域10a包括第一颜色子像素区域P 1、第二颜色子像素区域P 2、白色子像素区域W和第三颜色子像素区域P 3的情况下，透明绝缘层50位于每个第一颜色子像素区域P 1内的部分覆盖对应的第一颜色滤光膜41，透明绝缘膜50位于每个第二颜色子像素区域P 2的部分覆盖对应的第二颜色滤光膜42，透明绝缘膜50位于每个第三颜色子像素区域P 3内的部分覆盖对应的第三颜色滤光膜43，透明绝缘膜50位于每个白色子像素区域W的部分直接形成在基板10上。各白色子像素区域W内无需设置滤光膜。本公开一些实施例利用透明绝缘层50位于各白色子像素区域W内的部分作为透明色阻，可以确保各白色子像素区域W内白光有机发光二极管8发出的白光在穿过透明绝缘层50射出后显示为白光，并满足各白色子像素区域W的显示需求。
在上述实施方式的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限 于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
