技术领域

背景技术
有机发光二极管(Organic Light Emitting Display，OLED)显示面板因具有自发光、反应快、视角广、亮度高、色彩艳、轻薄等优点而得到人们的广泛重视。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。并且在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互组合。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的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。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。
需要注意的是，附图中各图形的尺寸和形状不反映真实比例，目的只是示意说明本公开内容。并且自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。
图1为相关技术中一种显示面板的俯视结构示意图，如图1所示，该显示面板可以包括多个子像素P，为了实现彩色显示，显示面板中的多个子像素P可以分为：红色子像素P_R、绿色子像素P_G及蓝色子像素P_B。图2为图1中虚线aa’处的剖视结构示意图，结合图1和图2，该显示面板可以包括：基板01，位于基板01上的驱动膜层02，位于驱动膜层02背离基板01一侧的阳极03，位于阳极03背离基板01一侧的阴极07，位于阳极03与阴极07 之间的发光功能层，位于阴极07背离基板01一侧的彩膜层08，以及位于彩膜层08背离基板01一侧的封装层09，其中，发光功能层可以包括：位于阳极03上的空穴注入层04，位于空穴注入层04上的发光层05，位于发光层05上的电子传输层06。其中，彩膜层08可以包括：红色(R)滤光部、绿色(G)滤光部及蓝色滤光部(图2中未示出)，发光功能层可以发出白色光线，发光层出射的光线经彩膜层08后，可以发出不同颜色的光线，从而实现彩色显示。由于显示面板中的各子像素共用发光功能层，即发光功能层为整层设置，并且，发光功能层中的有些有机层中的载流子较多，容易出现子像素之间的横向串扰，例如图2中，需点亮红色子像素P_R，而绿色子像素P_G无需点亮，由于空穴注入层04中载流子q较多，较多的载流子q极有可能沿空穴注入层04移动至相邻的绿色子像素P_G中，即引起横向导电，导致不该发光的绿色子像素P_G被点亮，引起颜色串扰，从而影响显示面板的显示效果。
鉴于此，本公开实施例提供了一种显示面板、其驱动方法及显示装置，图3为本公开实施例提供的显示面板的剖视结构示意图，如图3所示，该显示面板可以包括：
衬底基板10；在具体实施过程中，衬底基板10可以是硅基板，也可以是玻璃基板，本领域技术人员可以根据实际需要来选择相应材质的衬底基板10，在此不做限定。
多个发光器件20，位于衬底基板10之上；发光器件20可以包括：层叠设置的第一电极201、第二电极202，以及位于第一电极201和第二电极202之间的发光功能层203；在本公开实施例中，第一电极为阳极，第二电极为阴极；或者，第一电极为阴极，第二电极为阳极，此处不做限定。其中，发光功能层203可以包括空穴注入层、空穴传输层、发光层和电子传输层等有机层，或者，也可以包括其他有机层，此处不做限定。
阻隔结构30，位于发光功能层203与衬底基板10之间的膜层；阻隔结构30在衬底基板10上的正投影，位于相邻的发光器件20在衬底基板10上的正投影之间；
其中，阻隔结构30被配置为在电信号的控制下产生垂直于衬底基板10的电场。
在本公开实施例中，该显示面板可以包括多个子像素，多个子像素可以分为红色子像素、绿色子像素及蓝色子像素，每一个子像素中设有一个发光器件20。该显示面板中的各发光器件20可以共用发光功能层203，发光功能层203中的各有机层均为整层设置。在具体实施时，可以在发光功能层203的出光侧设置彩膜层，发光功能层可以发出白色光线，发光层出射的光线经彩膜层后，可以发出不同颜色的光线，从而实现彩色显示。
本公开实施例提供的显示面板中，通过在相邻的发光器件20之间设置阻隔结构30，阻隔结构30接收电信号后能够产生垂直于衬底基板10所在平面的方向的电场，该电场的方向可以是指向发光器件20的发光面方向，如图3中箭头X所示的方向，也可以是与图3中箭头X所示的方向相反的方向。通过控制阻隔结构30产生的垂直于衬底基板10所在平面的方向的电场，可以使发光功能层203中沿与衬底基板10所在平面平行的方向Y传导的载流子，在该电场的电场力作用下沿X方向(或与Z相反的方向)移动，从而使得相邻发光器件20之间的发光功能层203中的载流子处于耗尽状态，对应区域的发光功能层203处于高阻态，从而阻断了发光功能层203中的载流子沿Y方向移动，避免了对相邻发光器件的串扰，从而提高了显示面板的显示效果。
本公开实施例提供的显示面板中，在相邻的发光器件20之间设置阻隔结构30，且该阻隔结构30位于发光功能层203和衬底基板10之间的膜层，通过向阻隔结构30加载电信号，可以在垂直于衬底基板10所在平面的方向产生电场，在电场作用下，发光功能层203中的载流子将沿垂直于衬底基板10所在平面的方向运动，从而阻断了发光功能层203中的载流子沿平行于衬底基板10所在平面的方向运动，降低了该发光功能层203的横向导电能力，避免了横向串扰的发生，提高了显示面板的显示效果。
图4为本公开实施例提供的显示面板的另一剖视结构示意图，如图3和图4所示，上述阻隔结构30可以包括：层叠设置的介质层301和导电层302， 其中，介质层301位于导电层302和发光功能层203之间。通过在导电层302和发光功能层203之间设置介质层301，而该介质层301的相对介电常数往往大于1，能够提高导电层302和发光功能层203之间的电场强度，从而能够将阻隔结构30对应位置的发光功能层203中的载流子最大限度地耗尽，避免了横向串扰的发生，提高了显示效果。
继续参照图4，以第一电极201为阳极为例，发光功能层203中靠近第一电极201的有机膜层中，大部分载流子为空穴，例如，空穴传输层中的大部分载流子为空穴，通过向导电层302施加电信号，产生电场方向与图中X方向相反的电场，可以驱动空穴向介质层301移动，空穴移动到介质层301的表面处，可以被介质层301表面处的缺陷俘获，从而使相邻发光器件20之间的位置处的发光功能层203中的载流子耗尽，阻断载流子的横向传输。
在具体实施过程中，介电层301可以是由无机材料制成的，比如，介质层301的材料可以包括二氧化硅和氮化硅中的至少一种，即介质层301可以是由二氧化硅SiO 2制成的，也可以是由氮化硅SiN制成的，或者可以是由SiO 2和SiN掺杂制成的，在此不做限定。此外，由无机材料制成的介质层301通过制作工艺可以制作相对较薄的膜层，进而保证了显示面板的轻薄化设计。
在具体实施时，本公开实施例提供的上述显示面板中，如图3和图4所示，各发光器件20的第一电极201分立设置，也就是说，相邻的第一电极201之间间隔预设距离，在实际应用过程中，可以通过向不同的第一电极201分别施加电压，来驱动不同的发光器件20发光，并且，为了便于控制，各发光器件20可以共用第二电极202，即第二电极202可以为整层设置。
导电层302与第一电极201中的至少一个膜层同层设置，这样，在制作过程中，可以将导电层302与第一电极201中的至少一个膜层采用同一构图工艺制作，节省制作步骤，从而节约制作成本。阻隔结构30在衬底基板10上的正投影，与第一电极201在衬底基板10的正投影互不交叠，这样，可以避免阻隔结构30与第一电极201出现短接。
在具体实施过程中，可以是在全部相邻两个第一电极201之间均设置阻 隔结构30，也可以是在至少部分相邻两个第一电极201之间设置阻隔结构30，当然，可以根据对发光功能层203中载流子的传导能力的实际应用要求采用其它方式来设置阻隔结构30，在此不再一一详述。
图5为本公开实施例提供的显示面板的另一剖视结构示意图，如图5所示，第一电极201包括依次远离衬底基板10的第一导电电极2011、金属反射层2010和第二导电电极2012，导电层302与第一导电电极2011同层设置。这样，在制作过程中，可以将导电层302与第一导电电极2011采用同一构图工艺制作，节省制作步骤，从而节约制作成本，比如，在衬底基板10上形成一层导电膜层，然后利用一次构图工艺形成第一导电电极2011和导电层302的图案。在具体实施时，上述金属反射层2010可以为金属薄膜，例如可以为银薄膜或镁薄膜等。
此外，由于相邻的第一电极201之间间隔的预设距离较小，为了避免第一电极201与导电层302短接，也可以将导电层302与第一电极201异层设置，例如，可以将导电层302设置在第一电极201靠近衬底基板10的一侧，并且，为了节省工艺成本，也可以将导电层302设置为与第一电极201靠近衬底基板10一侧的其他导电膜层位于同一膜层。
在本公开实施例中，同样参照图5，介质层301靠近发光功能层203一侧的表面存在表面缺陷。具体可以是将介质层301的表面进行粗糙化处理，增加介质层301表面的表面比，从而增加介质层301的缺陷量，从而提高介质层301俘获载流子的能力，增强阻隔结构30对载流子的阻隔效果，从而提高显示面板的显示效果。
在本公开实施例中，上述显示面板还可以包括：电源信号线；电源信号线与导电层耦接，被配置为向导电层提供电信号。在具体实施时，可以将电源信号线设置为一端与导电层耦接，另一端延伸至显示面板的边缘，并与驱动芯片耦接，通过驱动芯片向电源信号线提供电信号。也就是说，导电层可以通过电源信号线与驱动芯片耦接，并接收来自驱动芯片的电信号。具体来讲，可以通过驱动芯片控制导电层所接收到的电信号的具体情况，比如，可 以是驱动芯片输出高电平信号至导电层，也可以是驱动芯片输出低电平信号至导电层，在此不做限定。仍结合图3所示，在导电层302接收到来自驱动芯片的低电平信号时，阻隔结构30将产生与箭头X所示方向相反的电场。在导电层302接收到来自驱动芯片的高电平信号时，阻隔结构30将产生如箭头X所示方向的电场。
图6为本公开实施例提供的显示面板的俯视结构示意图，如图6所示，阻隔结构30为围绕发光器件20的环状结构。例如图6中，每一个阻隔结构30围绕一个发光器件20，显示面板中的各发光器件20的周围均围绕一个阻隔结构30，当然，也可以仅在部分发光器件20的周围设置阻隔结构30，此处不做限定，或者，也可以将阻隔结构30设置为围绕两个或两个以上的发光器件20，此处不对阻隔结构30围绕的发光器件20的数量进行限定。在实际应用中，可以根据发光功能层在不同区域处载流子的分布情况，来对应地设置阻隔结构30，在此不做限定。另外，图6中以阻隔结构30为环状结构为例进行示意，在具体实施时，阻隔结构30也可以设置为条状或半包围状等非环状结构，此处不做限定。
图7为本公开实施例提供的显示面板另一俯视结构示意图，如图7所示，在本公开实施例中，多个发光器件20沿第一方向Z1和第二方向Z2呈阵列排布，第一方向Z1与第二方向Z2相互交叉；在第一方向Z1上，相邻的两个阻隔结构30至少间隔一个发光器件20。通过在发光器件20周围设置阻隔结构30，可以防止该发光器件20与相邻的发光器件20出现横向串扰现象，因而，在相邻的两个发光器件20中的一个发光器件20的周围设置阻隔结构30，就可以防止这两个发光器件20之间出现横向串扰现象，因此，本公开实施例中，在第一方向Z1上，相邻的两个阻隔结构20之间至少间隔一个发光器件20，可以在有效避免发光器件20之间出现横向串扰的情况下，减少显示面板中阻隔结构30的数量。
其中，本公开实施例中的显示面板还可以包括多条数据线和多条栅线，其中，数据线的延伸方向与栅线的延伸方向相互交叉，第一方向Z1可以是沿 数据线延伸的方向，第二方向Z2可以是沿栅线延伸的方向。
继续参照图7，在本公开实施例中，在第一方向Z1上，相邻的两个阻隔结构30至少间隔一个发光器件20，且在第二方向Z2上排列的一排发光器件20中，每一个发光器件20的周围均围绕一个阻隔结构30，图7中以在第一方向Z1上相邻的两个阻隔结构30间隔一个发光器件20为例，这样，可以避免每一个发光器件20与其他发光器件20出现横向串扰，并且，相比于图6所示的结构，可以使显示面板中阻隔结构30的数量减少一半。并且，在具体实施过程中，与第二方向Z2平行且靠近显示面板边缘的发光器件20周围不设置阻隔结构30，也有利于显示面板的窄边框设计。
图8为本公开实施例提供的显示面板另一俯视结构示意图，如图8所示，本公开实施例中，也可以设置为：在第二方向Z2上，相邻的阻隔结构30至少间隔一个发光器件20，且在第一方向Z1上排列的一排发光器件20中，每一个发光器件20的周围均围绕一个阻隔结构30，并且，在具体实施过程中，与第一方向Z1平行且靠近显示面板边缘的发光器件20周围也可以不设置阻隔结构30，有利于显示面板的窄边框设计。
图9为本公开实施例提供的显示面板另一俯视结构示意图，如图9所示，本公开实施例中，在第一方向Z1上，相邻的两个阻隔结构30至少间隔一个发光器件20，且在第二方向Z2上，相邻的两个阻隔结构30至少间隔一个发光器件20。这样，在有效减小各发光器件20之间的横向串扰的基础上，使显示面板中阻隔结构30的数量较少，并且，一般相邻的发光器件20之间的间隙的尺寸较小，这样设置可以防止同一间隙中设置两个间隔结构30，避免两个间隔结构30出现短接。
图9中，以在第一方向Z1上，相邻的两个阻隔结构30间隔两个发光器件20，在第二方向Z2上，相邻的两个阻隔结构30间隔两个发光器件20为例进行示意，在具体实施时，在第一方向Z1(或第二方向Z2)上，相邻的两个阻隔结构30间隔的发光器件20也可以为其他数量，此处不做限定。图10为本公开实施例提供的显示面板另一俯视结构示意图，例如图10中，在第一方 向Z1上，相邻的两个阻隔结构30间隔一个发光器件20，在第二方向Z2上，相邻的两个阻隔结构30间隔一个发光器件20。在具体实施过程中，图9和图10所示的结构中，分别沿第一方向Z1和第二方向Z2，每间隔一个(或两个)发光器件20设置一个阻隔结构30，一方面，可以降低制作工艺成本；另一方面，相邻两发光器件20共享同一阻隔结构30，保证了对显示面板中各个发光功能层中载流子的均匀去除，从而保证了对相邻两第一电极间的横向电场的充分阻断，提高了显示效果；此外，兼顾了显示面板的轻薄化设计。
当然，在具体实施过程中，阻隔结构的设置方式可以按照图6至图10任一所示的方式，但不限于上述方式，除了上述提供几种设置方式外，还可以根据实际应用需要采用其它设置方式来设置阻隔结构，在此不再一一赘述。
基于同样的发明构思，本公开实施例还提供了一种显示装置，图11为本公开实施例提供的显示装置的俯视结构示意图，如图11所示，该显示装置包括如本公开实施例提供的上述任一显示面板100。
在具体实施时，该显示装置可以为：手机(如图11所示)、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪、手表等任何具有显示功能的产品或部件。该显示装置的实施可以参见上述显示面板的实施例，重复之处不再赘述。
基于同样的公开构思，本公开实施例还提供了一种显示面板的驱动方法，图12为本公开实施例提供的显示面板的驱动方法的流程图，如图12所示，本公开实施例提供的驱动方法，可以包括：
S101：向阻隔结构加载电信号，以控制阻隔结构产生垂直于衬底基板所在平面的方向的电场，使发光功能层中的载流子在电场的作用下，沿垂直于衬底基板所在平面的方向运动。
在具体实施过程中，可以通过驱动芯片向电源信号线加载电信号，以向阻隔结构加载电信号，所加载的电信号可以是高电平信号，也可以是低电平信号，在此不做限定。相应地，阻隔结构所产生的电场为根据所加载的电信号的具体情况所形成的，该电场方向主要取决于所加载的电信号的具体数值， 其方向可以是指向显示面板的发光面方向，也可以是背离显示面板的发光面方向，在此不做限定。
在本公开实施例中，在阻隔结构所产生的电场作用下，驱动发光功能层中的载流子沿垂直于衬底基板所在平面的方向运动，从而阻断了发光功能层中的载流子的横向运动，避免了横向串扰，提高了显示面板的显示效果。
