随着随着人们节能减排的意识逐步增强，RGBW技术的节能优势在液晶面板的发展中日益突出和显现。市场对应用RGBW技术的面板需求也随之越来越强烈。在RGBW技术给消费者带来白画面下高亮度、高对比度的同时，也可以降低背光的亮度，使整个液晶面板的能耗降低，达到节能的作用。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合 附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不设置为限定本申请。
本申请提供的显示面板，可以应设置为液晶显示装置或者液晶显示设备之中，例如，液晶显示屏、液晶电视等等。本申请的面板可以是扭曲向列型(Twisted Nematic，TN)面板、平面转换(In-PaneSwitcing，IPS)面板、多象限垂直配向技术(Multi-domain Vertica Aignment，VA)面板。当然，也可以是其他类型的面板，适用即可。
如图1以及图2所示，在一个实施例中，提供了一种显示面板，包括多条扫描线100、多条数据线200、数据驱动(未标号)以及多个像素行(未标号)
多条扫描线100，沿第一方向(例如水平方向)延伸，设置为逐行提供扫描信号。
多条数据线200，沿第二方向(例如竖直方向)延伸且与扫描线100交叉排列，设置为提供数据信号。数据信号包括多个子信号。扫描线100提供一个扫描信号时，数据线200提供一个子信号。
数据驱动连接数据线200，设置为控制数据信号的输出。
像素行包括多个像素组300。像素组300包括偶数个像素单元310。像素单元310包括第一子像素311、第二子像素312、第三子像素313以及第四子像素314。第一子像素311、第二子像素312、第三子像素313以及第四子像素314均连接数据线200与扫描线100且在一帧时间内各自接受一个子信号。且第一子像素311、第二子像素312、 第三子像素313以及第四子像素314均在扫描线100上的扫描信号的作用下打开，在数据线200的数据信号作用下充电。
本申请实施例中，在一帧时间内，一个像素组300内，第一子像素311、第二子像素312、第三子像素313以及第四子像素314所接受到的处于正极性的子信号的数量与处于负极性的子信号的数量相同。因此，可以在单颜色显示时，在一帧时间内，有效预防公共电极因为数据信号的耦合作用而产生电压偏移。进而可以在上下帧数据信号极性反转的情况下，有效改善画面闪烁的问题。
同时，本申请的多个像素行的第一子像素311、第二子像素312、第三子像素313以及第四子像素314排列成多个像素列。同一像素列所接受到的数据信号包括处于正极性的子信号，也包括处于负极性的子信号，进而可使得同一列像素列上接受到的数据信号的极性不完全相同，防止该列由于对应的公共电极因耦合作用而产生电压偏移，进而防止该列在上下帧数据信号极性反转的情况下，产生竖纹。进而进一步提高显示性能。
本申请具体实施例中，可以设置像素行包括多个像素组300，像素组300包括偶数个像素单元310。此时，可以设置像素组300包括两个像素单元310，且像素组300内的数据信号极性分布可以为+、-、+、-、-、+、-、+。当然本申请并不以此为限制。
在一个实施例中，同一像素列所接受到的数据信号分为多个信号组。一个信号组内的数据信号包括偶数个子信号。且偶数个子信号中，处于正极性的子信号的数量与处于负极性的子信号的数量相同。因此， 有利于使得正极性的子信号与负极性的子信号对公共电极的耦合作用相互抵消，进而有效地防止竖纹的产生。为了使得显示更加均匀，可以设置各个信号组内包括的子信号的数量相同。
同一列像素列上的数据信号越规律，越便于设置。并且每个信号组包括的子信号数量越少，信号组的组数越多，越有利于使得各像素列各处性质比较均匀。因此，可以设置信号组的组数为多组，且多组信号组周期性排列，形成若干信号周期。信号周期性排列即循环往复排列，因此，使得各像素列各处性质更加均匀。当然，本申请实施例中，在设置数据信号的组数为多组时，各组数据信号也可以不周期性排列，每个信号组内包括的子信号数量的数量可以相同，也可以不同。
在一个实施例中，设置信号组的组数为多组，且多组信号组周期性排列的同时，为了进一步增强同一列像素列上的数据信号的规律性，可以设置一个信号周期包括一个信号组。前半个信号周期内的各子信号的极性相同，后半个信号周期内各子信号的极性相同。且前半个信号周期内的子信号的极性与后半个信号周期内的子信号的极性相反。这样使得数据信号施加更有规律，进而便于数据信号的输出设置。当然，一个信号周期也可以包括一个以上信号组，本申请对比不做限制。
更具体地，在一个实施例中，可以设置前半个信号周期具有一个子信号，后半个信号周期具有一个子信号，前半个信号周期内的子信号与后半个信号周期内的子信号极性相反。此时，同一列像素列上的数据信号的极性正负交替，可有效防相互抵消对公共电极的耦合作用。
在一个实施例中，各像素列所接受到的相邻的子信号的极性相反， 进而在像素列实现在列方向上的正负极性的数据信号可及时相互抵消对公共电极的耦合作用。同时还可设置各像素单元内所接受到的相邻的子信号的极性相反，进而在像素单元内的正负极性的数据信号可及时相互抵消对公共电极的耦合作用。同一像素组的相邻像素单元接受到的相邻的子信号极性相同，进而便于实现同一像素行上的相同颜色的子像素(第一子像素311或第二子像素312或第三子像素313或第四子像素314)接受到的处于正极性的子信号的数量与处于负极性的子信号的数量相同。
当然，在第一子像素311、第二子像素312、第三子像素313以及第四子像素314排列顺序合理的情况下，也可设置各像素组300内所接受到的相邻的子信号的极性相反。例如，第一子像素311、第二子像素312、第三子像素313以及第四子像素314在一个像素组300内的排列顺序为，第一子像素311、第二子像素312、第三子像素313、第四子像素314、第二子像素312、第三子像素313、第四子像素314、第一子像素311，则该像素组300内的接收到的子信号极性分布可以为+、-、+、-、+、-、+、-。
在一个实施例中，同一像素行内的各像素组300周期性排列，即相同的像素组300循环往复排列，可有效提高像素行上显示均匀性。相同的像素组300表示像素组中的第一子像素311、第二子像素312、第三子像素313、第四子像素314的排列方式相同，像素组内接受到的子信号极性分布情况也相同。
本申请实施例中，同一像素行内的各像素组300也可不周期排布， 本申请对此不做限制。例如，同一像素行内的各像素组中的第一子像素311、第二子像素312、第三子像素313、第四子像素314的排列方式相同，同一像素行的各像素组300内接受到的子信号极性分布情况不同。或者，同一像素行的各像素组300内接受到的子信号极性分布情况相同，而同一像素行的各像素组300中的第一子像素311、第二子像素312、第三子像素313、第四子像素314的排列方式不同。或者，同一像素行的各像素组300内接受到的子信号极性分布情况不同，同一像素行的各像素组中的第一子像素311、第二子像素312、第三子像素313、第四子像素314的排列方式也不同。
本申请实施例中，第一子像素311可以为红色子像素R，第二子像素312可以为绿色子像素G，第三子像素313可以为蓝色子像素B，第四子像素314可以白色子像素W。或者第一子像素、第二子像素312、第三子像素313、第四子像素314也可以是其他颜色子像素，本申请对此不作过多限制。但是，第一子像素311、第二子像素312、第三子像素313、第四子像素314由于是不同颜色的子像素，其性能不同。
因此，在一个实施例中，同一像素组300的各像素单元310内的第一子像素311、第二子像素312、第三子像素313、第四子像素314按照相同的顺序排列，进而可以各像素单元性能的一致性。
进一步地，可设置在同一像素行内的各像素组300周期性排列的同时，同一像素行的各像素单元310内的第一子像素311、第二子像素312、第三子像素313及第四子像素314按照相同的顺序排列，进 而便于设计。
当然，本申请对此不做限制，同一像素组300的各像素单元310内的第一子像素311、第二子像素312、第三子像素313、第四子像素314也可按照不同的顺序排列。或者，也可以同一像素组300的各像素单元310内的第一子像素311、第二子像素312、第三子像素313、第四子像素314按照相同的顺序排列，但是同一像素行内的不同的像素组300内的第一子像素311、第二子像素312、第三子像素313、第四子像素314可以按照不同的顺序排列。
具体地，在一个实施例中，所有像素行的像素单元310内的第一子像素311、第二子像素312、第三子像素313、第四子像素314均按照相同的顺序排列，例如按照第一子像素311、第二子像素312、第三子像素313、第四子像素314的顺序排列，进而使得布局简单。
在另一个实施例中，奇数行像素行的像素单元内的第一子像素311、第二子像素312、第三子像素313、第四子像素314均按照第一种排列方式排列，例如按照第一子像素311、第二子像素312、第三子像素313、第四子像素314的顺序排列。偶数行像素行的像素单元内的第一子像素311、第二子像素312、第三子像素313、第四子像素314均按照第二种排列方式排列，例如按照第三子像素313、第四子像素314、第一子像素311、第二子像素312的顺序排列，进而使得显示面板在各处亮度均匀。
第四子像素314可以为提亮子像素(例如白色子像素)。因此， 该实施例中提亮子像素不位于同一像素列，进而使得显示面板在各处均匀提亮。
当然，本申请实施例中，各像素行的像素单元310内的第一子像素311、第二子像素312、第三子像素313、第四子像素314的排列顺序也可与上述两个实施例不同。本申请对此不做限制。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
