具体实施方式
下面将结合附图，对本公开实施例中的技术方案进行清楚、完整地描述参考在附图中示出并在以下描述中详述的非限制性示例实施例，更加全面地说明 本公开的示例实施例和它们的多种特征及有利细节。应注意的是，图中示出的特征不是必须按照比例绘制。本公开省略了已知材料、组件和工艺技术的描述，从而不使本公开的示例实施例模糊。所给出的示例仅旨在有利于理解本公开示例实施例的实施，以及进一步使本领域技术人员能够实施示例实施例。因而，这些示例不应被理解为对本公开的实施例的范围的限制。
除非另外特别定义，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。此外，在本公开各个实施例中，相同或类似的参考标号表示相同或类似的构件。
有机发光二极管(Organic Light-Emitting Diode,OLED)显示面板可由逐行扫描方式驱动，这种驱动方法在提高刷新频率时，可能造成像素单元的充电时间不足，进而导致画面质量较差，阻碍了大尺寸、高分辨率OLED显示产品的发展。
OLED显示面板也可以采用双行扫描的方式，即任何时刻都有两行像素单元处于充电状态，可为每个像素单元提供两倍于原有逐行扫描驱动方式的充电时间，保证了画面质量，尤其适合于大尺寸、高分辨率的OLED显示产品。
另一方面，在OLED显示面板中，各个像素单元中的驱动晶体管的阈值电压由于制备工艺可能彼此之间存在差异，而且由于例如温度变化的影响，驱动晶体管的阈值电压也会产生漂移的现象。因此，各个驱动晶体管的阈值电压的不同也可能会导致显示面板显示不均匀。因此，需要对驱动晶体管的阈值电压进行补偿。
本公开至少一实施例提供的显示面板中的像素单元可以通过感测发光元件的发光电流或发光电压实现像素单元中驱动晶体管的阈值补偿。当采用上述补偿方式时，需要设置感测线，感测线与其它线路(例如栅线)之间会产生寄生电容，从而增大了电路的RC负载，降低了感测速度，进而容易导致感测时间不足。
本公开至少一实施例提供的显示面板、显示设备和补偿方法可以通过双行扫描及共用感测线提升像素单元的开口率，进一步地还可以为像素单元提供更充足的充电时间以及加快感测速度。
例如，本公开至少一实施例提供的显示面板、显示设备和补偿方法可提升 像素单元的开口率至50％以上、增加一倍的充电时间、降低30％寄生电容。
本公开至少一实施例提供一种显示面板，包括至少一个像素单元组、至少一条感测线、多条栅线、多条第一数据线和多条第二数据线，每个像素单元组包括位于两行和多列中的多个像素单元，每个像素单元组中的像素单元与同一条栅线连接，以接收相同的栅极信号，每个像素单元组中每列两个像素单元中的一个与其对应的一条第一数据线连接，每个像素单元组中每列两个像素单元中的另一个与其对应的一条第二数据线连接，每个像素单元组中的像素单元与同一条感测线连接，像素单元包括发光元件，感测线用于感测发光元件的发光电流或发光电压。

例如，如图5所示，在本公开实施例提供的显示面板10中，感测控制电路120包括第三晶体管T3。第三晶体管T3的第一极与第二节点N2连接，第三晶体管T3的栅极与感测控制线SC连接以接收感测控制信号，第三晶体管T3的第二极与感测线S连接。
例如，有机发光二极管OLED的阳极与第二节点N2连接，有机发光二极管OLED的阴极与第二电源线VSS连接以接收第二电源电压。
需要说明的是，本公开的实施例中采用的晶体管均可以为薄膜晶体管或场效应晶体管或其他特性相同的开关器件。这里采用的晶体管的源极、漏极在结构上可以是对称的，所以其源极、漏极在结构上可以是没有区别的。在本公开 的实施例中，为了区分晶体管除栅极之外的两极，直接描述了其中一极为第一极，另一极为第二极，所以本公开实施例中全部或部分晶体管的第一极和第二极根据需要是可以互换的。例如，本公开实施例所述的晶体管的第一极可以为源极，第二极可以为漏极；或者，晶体管的第一极为漏极，第二极为源极。此外，按照晶体管的特性区分可以将晶体管分为N型和P型晶体管，本公开的实施例对晶体管的类型不作限定，本领域技术人员可以根据实际需要利用N型和/或P型晶体管实现本公开中的实施例。
需要说明的是，本公开的实施例包括但不局限于图4或图5所示的像素单元，也可以是其它结构的像素单元。例如，感测控制电路120不局限于连接在第二节点N2的位置，也可以连接在其它可以感测有机发光二极管OLED的发光电流或发光电压的位置。又例如，像素单元还可以包括其它电路，例如用于对第一晶体管的栅极进行复位的复位电路，用于控制有机发光二极管OLED发光的发光控制电路等。
例如，以下以一个像素单元组为例介绍显示面板的工作过程。例如，在有机发光二极管OLED的发光阶段，由感测控制线SC分别控制像素单元组20中每个像素单元100中的第三晶体管T3依次开启，从而用一条感测线S分别感测像素单元组20中多个有机发光二极管OLED的发光电流或发光电压。例如，感测线S感测到的发光电压为V1，该像素单元100预设的发光电压为V0，则补偿数据VC＝V1-V0。例如，感测线S感测到的发光电流为I1，该像素单元预设的发光电流为I0，则补偿电流IC＝I1-I0，补偿数据VC为补偿电流IC对应的补偿电压，补偿数据VC和补偿电流IC的关系可以通过试验建立函数关系或对应表，从该函数关系或对应表根据补偿电流IC可还原补偿数据VC。例如，用该像素单元100施加的原始数据信号Vdata0减去补偿数据VC得到更新数据信号Vdata，即更新数据信号Vdata＝Vdata0-VC。例如，得到更新数据信号Vdata后，可由数据驱动器11通过第一数据线D1或第二数据线D2向与该更新数据信号Vdata对应的像素单元100提供更新数据信号Vdata。这样即可实现像素单元100中第一晶体管T1的阈值电压补偿和沟道迁移率补偿，提高显示的准确性。
本公开的实施例还提供一种显示设备1，如图6所示，该显示设备1包括本公开任一实施例提供的显示面板10。
例如，本公开的实施例提供的显示设备1可以为：手机、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。
本公开的实施例还提供一种用于本公开任一实施例提供的显示面板的补偿方法，如图7所示，该补偿方法的一个示例可以包括如下操作：
S10：用一条感测线在一条栅线选通的不同时段分别感测栅线对应的像素单元组中多个有机发光二极管的发光电流或发光电压。
例如，本公开实施例提供的补偿方法还包括如下操作：
S20：根据感测线感测到的像素单元组中多个有机发光二极管的发光电流或发光电压生成补偿数据；以及
S30：根据补偿数据分别补偿像素单元组中多个像素单元被施加的数据信号。
例如，在操作S10中，用一条感测线在一条栅线选通的不同时段分别感测栅线对应的像素单元组中多个有机发光二极管的发光电流或发光电压，可以是在有机发光二极管的发光阶段，由感测控制线分别控制像素单元组中每个像素单元中的第三晶体管依次开启，从而用一条感测线分别感测像素单元组中多个有机发光二极管的发光电流或发光电压。
例如，在操作S20中，根据感测线感测到的像素单元组中多个有机发光二极管的发光电流或发光电压生成补偿数据，可以是用感测到的发光电流或发光电压减去该像素单元预设的发光电流或发光电压以得到补偿数据。例如，感测线感测到的发光电压为V1，该像素单元预设的发光电压为V0，则补偿数据VC＝V1-V0。例如，感测线感测到的发光电流为I1，该像素单元预设的发光电流为I0，则补偿电流IC＝I1-I0，补偿数据VC为补偿电流IC对应的补偿电压，补偿数据VC和补偿电流IC的关系可以通过试验建立函数关系或对应表，从该函数关系或对应表根据补偿电流IC可还原补偿数据VC。
例如，在操作S30中，根据补偿数据分别补偿像素单元组中多个像素单元被施加的数据信号，可以是用施加到该像素单元的原始数据信号Vdata0减去补偿数据VC得到更新数据信号Vdata，即更新数据信号Vdata＝Vdata0-VC。
例如，得到更新数据信号Vdata后，可由数据驱动器11通过第一数据线或第二数据线向与该更新数据信号Vdata对应的像素单元提供更新数据信号Vdata。这样即可实现像素单元中第一晶体管的阈值电压补偿和沟道迁移率补偿，提高显示的准确性。
本公开实施例提供的显示面板、显示设备和补偿方法可以通过双行扫描及共用感测线提升像素单元的开口率、为像素单元提供更充足的充电时间以及加快感测速度。
虽然上文中已经用一般性说明及具体实施方式，对本公开作了详尽的描述，但在本公开实施例基础上，可以对之作一些修改或改进，这对本领域技术人员而言是显而易见的。因此，在不偏离本公开精神的基础上所做的这些修改或改进，均属于本公开要求保护的范围。
本申请要求于2016年12月01日递交的中国专利申请第201611090721.1号的优先权，在此全文引用上述中国专利申请公开的内容以作为本申请的一部分。
